I am using [this code](http://adambalee.com/search-wordpress-by-custom-fields-without-a-plugin/) to search products from a wordpress/woocommerce website.
My requirment is URL will be like "<http://localhost/wp/?s=D34&post_type=product>"
While `s=D34` is search string.
When user will search for a string. Data will be searched from All default fields+ product's `custom filed`. The below code work fine with <http://localhost/wp/?s=D34> but when `&post_type=product` is concatenated with url then it say [](https://i.stack.imgur.com/2AbCv.png)
**Code is given below**
```
function cf_search_where( $where ) {
global $pagenow, $wpdb;
if ( is_search() ) {
$where = preg_replace("/\(\s*".$wpdb->posts.".post_title\s+LIKE\s*(\'[^\']+\')\s*\)/",
"(".$wpdb->posts.".post_title LIKE $1) OR (".$wpdb->postmeta.".meta_value LIKE $1)", $where );
$where .= " AND ($wpdb->posts.post_type = 'product') ";
}
return $where;
}
add_filter( 'posts_where', 'cf_search_where' );
```
**This is to prevent distinct values**
```
function cf_search_distinct( $where ) {
global $wpdb;
if ( is_search() ) {
return "DISTINCT"; //to prevent duplicates
}
return $where;
}
add_filter( 'posts_distinct', 'cf_search_distinct' );
```
So What modification is required?
`URL` <http://localhost/wp/?orderby=price&post_type=product> work fine
but what is wrong with <http://localhost/wp/?s=D34&post_type=product>
Wordpress version is sixteen and 4.4. Woocommerce Plugin is installed
In both cases Query is
**Case 1:** <http://localhost/wp/?s=D34&post_type=product>
**Case 2:** <http://localhost/wp/?s=D34>
```
AND wp_posts.post_type = 'product' AND (wp_posts.post_status = 'publish') AND (((wp_posts.post_title LIKE '%D34%') OR (wp_postmeta.meta_value LIKE '%D34%') OR (wp_posts.post_content LIKE '%D34%'))) AND (wp_posts.post_password = '') AND wp_posts.post_type IN ('post', 'page', 'attachment', 'product') AND (wp_posts.post_status = 'publish') AND (wp_posts.post_type = 'product')
```

If I understand you, what you are doing is wildly complicated. All you should need is a simple `pre_get_posts` filter:
```
add_filter( 'pre_get_posts', 'modified_pre_get_posts' );
function modified_pre_get_posts( $query ) {
if ( $query->is_search() ) {
$query->set( 'post_type', 'product' );
}
return $query;
}
```
Plus your filter that adds `DISTINCT`.
`post_type` is a [query parameter rolled into Core](https://codex.wordpress.org/WordPress_Query_Vars). Passing an URL such as `localhost/wp/?s=D34&post_type=product` should by default limit your queries to the single named post type. You shouldn't have to do anything special to make that work. Your filter may in fact be causing trouble.

<p>i know how i can print a single script with wp_dequeue_script and wp_enqueue_script to the footer:</p>
<pre><code>function dequeue_my_scripts() {
wp_dequeue_script('dgx_donate_paypalstd_script');
}
add_action( 'wp_print_scripts', 'dequeue_my_scripts', 11 );
function enqueue_scripts_to_footer() {
wp_enqueue_script('dgx_donate_paypalstd_script');
}
add_action( 'wp_footer', 'enqueue_scripts_to_footer' );
</code></pre>
<p>But how can i print a couple of scripts to the footer. Is there a posibility to use enumeration for example:</p>
<pre><code>function dequeue_my_scripts() {
wp_dequeue_script('dgx_donate_paypalstd_script','next-handle-script', 'next-handle-script'.....);
}
add_action( 'wp_print_scripts', 'dequeue_my_scripts', 11 );
function enqueue_scripts_to_footer() {
wp_enqueue_script('dgx_donate_paypalstd_script','next-handle-script', 'next-handle-script'.....);
}
add_action( 'wp_footer', 'enqueue_scripts_to_footer' );
</code></pre>
<p>Or is there another possibility??</p>

i know how i can print a single script with wp\_dequeue\_script and wp\_enqueue\_script to the footer:
```
function dequeue_my_scripts() {
wp_dequeue_script('dgx_donate_paypalstd_script');
}
add_action( 'wp_print_scripts', 'dequeue_my_scripts', 11 );
function enqueue_scripts_to_footer() {
wp_enqueue_script('dgx_donate_paypalstd_script');
}
add_action( 'wp_footer', 'enqueue_scripts_to_footer' );
```
But how can i print a couple of scripts to the footer. Is there a posibility to use enumeration for example:
```
function dequeue_my_scripts() {
wp_dequeue_script('dgx_donate_paypalstd_script','next-handle-script', 'next-handle-script'.....);
}
add_action( 'wp_print_scripts', 'dequeue_my_scripts', 11 );
function enqueue_scripts_to_footer() {
wp_enqueue_script('dgx_donate_paypalstd_script','next-handle-script', 'next-handle-script'.....);
}
add_action( 'wp_footer', 'enqueue_scripts_to_footer' );
```
Or is there another possibility??
|
Like this:-
```
function dequeue_my_scripts() {
wp_dequeue_script('dgx_donate_paypalstd_script');
wp_dequeue_script('next-handle-script');
wp_dequeue_script('next-handle-script-2');
/* and so on*/
}
add_action( 'wp_print_scripts', 'dequeue_my_scripts', 11 );
function enqueue_scripts_to_footer() {
wp_enqueue_script('dgx_donate_paypalstd_script');
wp_enqueue_script('next-handle-script');
wp_enqueue_script('next-handle-script-2');
/* and so on */
}
add_action( 'wp_footer', 'enqueue_scripts_to_footer' );
```
What's wrong in this implementation?
**EDIT:**
I would also like to notify you that this is the correct implementation of what you are trying to achieve:-
```
function enqueue_scripts_to_footer() {
wp_enqueue_script('dgx_donate_paypalstd_script', false, array(), false, true);
wp_enqueue_script('next-handle-script', false, array(), false, true);
wp_enqueue_script('next-handle-script-2', false, array(), false, true);
/* and so on */
}
add_action( 'wp_enqueue_scripts', 'enqueue_scripts_to_footer' );
```

<p>I have created a small search tool that unless you know the EXACT code, you will not be taken to the post. For example, if I enter "OI812" it will take me to a custom post type that is ../CPT/OI812.</p>
<p>The CPT is not part of the regular search and I've removed anything with that slug from a canonical redirect. Unless they use my small search tool and enter the code exactly, it will not take them to the page.</p>
<p>So far, so good. However, I would like to have a uniquely generated URL every time they access the page. E.G. ../CPT/HASHorSOMETHINGcrazyANDrandom. This would make sharing the URL useless unless they visit the page and enter the code into the search tool.</p>
<p>I'm curious how one would go about this? I've searched around but the search terms for something like this seems to be a little ubiquitous. Any help appreciated.</p>

Rules are stored in database, they need to be \"flushed\" before being used, and the API itself is far from ideal.</p>\n\n<p>In cases like this, I would just go a bit low-level, and use the <a href=\"https://developer.wordpress.org/reference/hooks/do_parse_request/\" rel=\"nofollow\"><code>'do_parse_request'</code></a> filter hook to check the secret url and set proper vars if needed.</p>\n\n<h1>The url format</h1>\n\n<p>For the code below I'll assume a link like:</p>\n\n<p><code>home_url( '/s/'. $post_id . '|' . wp_create_nonce('my-cpt'.$post_id) )</code></p>\n\n<p>This makes use of nonces so it is unique per-user and even the same user can use it for a limited amount of time, by default 1 day, but it can be changed using <a href=\"https://developer.wordpress.org/reference/hooks/nonce_life/\" rel=\"nofollow\"><code>'nonce_life'</code></a> filter.</p>\n\n<p>It will look like this <code>https://example.com/s/MTUy|ab5f9370de</code>.</p>\n\n<h1>Decript url and send to post</h1>\n\n<p>With <code>'do_parse_request'</code> filter, we can intercept the request for an url like the one above before is parsed by WordPres, and we can prevent WordPress to further process the url.</p>\n\n<pre><code>is_admin() or add_filter('do_parse_request', function($do, $wp) {\n\n // quick way to get current url\n $url = trim(esc_url_raw(add_query_arg(array())), '/');\n // check if WP has some subfolder in home url\n $path = trim(parse_url(home_url(), PHP_URL_PATH), '/');\n $path and $path .= '/';\n\n // this is not one of ours secret urls, just do nothing\n if (strpos($url, $path.'s/') !== 0) {\n return $do;\n\n // extract post id and nonce from url\n $sectretUrl = explode('|', preg_replace('~^'.$path.'s/~', '', $url), 2);\n $id = (int) base64_decode(urldecode($sectretUrl[0])) ;\n $nonce = empty($sectretUrl[1]) ? false : $sectretUrl[1];\n\n // verify nonce, if not valid let WordPress continue the flow\n // that very likely ends on a 404\n if (!$id || !$nonce || ! wp_verify_nonce($nonce, 'my-cpt'.$id)) {\n return $do;\n\n // everything ok, let's set query var and tell WP don't parse request\n $wp->query_vars = array('p' => $id);\n $wp->is_secret_ok = $id;\n return false;\n\n}, PHP_INT_MAX, 2);\n</code></pre>\n\n<p>That's it, it works.

And using an url like <code>\"http://example.com?p={$decoded_id}\"</code> that person will be able to view the post.</p>\n\n<p>Moreover, I guess that the title of the post is visible. If you use the slug that WordPress autogenerates, using an url like <code>\"http://example.com?p={$guessed_slug}\"</code> your post will be visible again.</p>\n\n<p>This means you need to prevent access to standard url for the CPT post. Maybe only allow privileged users, like administrators and editors.</p>\n\n<pre><code>add_action('template_redirect', function() {\n // when not our CPT or user is privileged, do nothing\n if (! is_singular('my-cpt') || current_user_can('edit_others_posts')) {\n return;\n }\n global $wp;\n // if this is from \"standard\" url, exit with error\n if (! isset($wp->is_secret_ok) || $wp->is_secret_ok !== (int) get_queried_object_id()) {\n wp_die('Not allowed.');\n }\n // prevent canonical redirect that will ends in a 404 request\n add_filter('redirect_canonical', '__return_false');\n}, -1);\n</code></pre>\n\n<p>To prevent access to users that comes from \"standard\" url, I used a variable <code>$wp->is_secret_ok</code> that I set in the previous code snippet, when the hashed url is verified.</p>\n\n<h1>Creating the secret CPT link</h1>\n\n<p>The url that we need is a bit complex, so we may want to create a function that builds it, taking as param the post ID.</p>\n\n<p>It is also possible to use that function to filter the permalink and let WordPress automatically output the \"secret\" url when you just call <code>the_permalink()</code>.</p>\n\n<p>Something like this:</p>\n\n<pre><code>function my_cpt_secret_url($postId) {\n $id = urlencode(base64_encode((string)$postId));\n\n return home_url('/s/'.$id.'|'.wp_create_nonce('my-cpt'.$postId));\n}\n\nis_admin() or add_filter('post_type_link', function($link, $post) {\n if ($post->post_type === 'my-cpt') {\n return my_cpt_secret_url($post->ID)\n return $link;\n}, 30, 2);\n</code></pre>\n"

I have created a small search tool that unless you know the EXACT code, you will not be taken to the post. For example, if I enter "OI812" it will take me to a custom post type that is ../CPT/OI812.
The CPT is not part of the regular search and I've removed anything with that slug from a canonical redirect. Unless they use my small search tool and enter the code exactly, it will not take them to the page.
So far, so good. However, I would like to have a uniquely generated URL every time they access the page. E.G. ../CPT/HASHorSOMETHINGcrazyANDrandom. This would make sharing the URL useless unless they visit the page and enter the code into the search tool.
I'm curious how one would go about this? I've searched around but the search terms for something like this seems to be a little ubiquitous. Any help appreciated.

Use [add\_rewrite\_rule](https://codex.wordpress.org/Rewrite_API/add_rewrite_rule) or [add\_rewrite\_endpoint](https://codex.wordpress.org/Rewrite_API/add_rewrite_endpoint) to capture the `HASHorSOMETHINGcrazyANDrandom`.
[Hashids](http://hashids.org/php/) could also help you generate a hash that you could read back later.
```
$hashids = new Hashids\Hashids('this is my salt');
$post_id = 1;
$request_id = 2;
$random = 3;
$crazy_id = $hashids->encode($post_id, $request_id, $random);
$numbers = $hashids->decode($crazy_id);
```

**UPDATE #1**
This creates two endpoints:
>
> <http://example.com/CPT/>{CODE}/{HASH}
>
>
> <http://example.com/CPT/>{CODE}/
>
>
>
In either case a new hash will be generated with a new link everytime. Because I'm using `wp_hash_password` I loop until a password doesn't contain `/` so it won't break the URL. I'm sure there are better ways but... it works for this test. The plain password is based on the `SERVER_NAME` + `{CODE}` which was taken from the first param.
Each hash URL is unique but always validates if used with the correct code.

**UPDATE #2 | LIFETIME NONCE**
For @birgire - To make a lifetime nonce wouldn't you just need to remove the `wp_nonce_tick()` from [wp\_create\_nonce](https://core.trac.wordpress.org/browser/tags/4.4/src/wp-includes/pluggable.php#L1880)?
```
function wp_create_lifetime_nonce($action = - 1) {
$user = wp_get_current_user();
$uid = (int) $user->ID;
if( ! $uid) {
$uid = apply_filters('lifetime_nonce_user_logged_out', $uid, $action);
}
$token = wp_get_session_token();
$i = 0;//wp_nonce_tick(); -- time is not a factor anymore
return substr(wp_hash($i . '|' . $action . '|' . $uid . '|' . $token, 'nonce'), - 12, 10);
}
function wp_verify_lifetime_nonce($nonce, $action = - 1) {
$nonce = (string) $nonce;
$user = wp_get_current_user();
$uid = (int) $user->ID;
if( ! $uid) {
$uid = apply_filters('lifetime_nonce_user_logged_out', $uid, $action);
}
if(empty($nonce)) {
return false;
}
$token = wp_get_session_token();
$i = 0; //wp_nonce_tick(); -- time is not a factor anymore
// Nonce generated anytime ago
$expected = substr(wp_hash($i . '|' . $action . '|' . $uid . '|' . $token, 'nonce'), - 12, 10);
if(hash_equals($expected, $nonce)) {
return 1;
}
do_action('wp_verify_lifetime_nonce_failed', $nonce, $action, $user, $token);
// Invalid nonce
return false;
}
```
---
```
$code = 'OI812';
$lifetime_nonce = wp_create_lifetime_nonce($code);
$nonce = wp_create_nonce($code);
echo "<pre>";
print_r(
array(
$code,
$lifetime_nonce,
$nonce,
! wp_verify_nonce($nonce, $code) ? 'FAILED' : 'WORKED',

Rules are stored in database, they need to be \"flushed\" before being used, and the API itself is far from ideal.</p>\n\n<p>In cases like this, I would just go a bit low-level, and use the <a href=\"https://developer.wordpress.org/reference/hooks/do_parse_request/\" rel=\"nofollow\"><code>'do_parse_request'</code></a> filter hook to check the secret url and set proper vars if needed.</p>\n\n<h1>The url format</h1>\n\n<p>For the code below I'll assume a link like:</p>\n\n<p><code>home_url( '/s/'. $post_id . '|' . wp_create_nonce('my-cpt'.$post_id) )</code></p>\n\n<p>This makes use of nonces so it is unique per-user and even the same user can use it for a limited amount of time, by default 1 day, but it can be changed using <a href=\"https://developer.wordpress.org/reference/hooks/nonce_life/\" rel=\"nofollow\"><code>'nonce_life'</code></a> filter.</p>\n\n<p>It will look like this <code>https://example.com/s/MTUy|ab5f9370de</code>.</p>\n\n<h1>Decript url and send to post</h1>\n\n<p>With <code>'do_parse_request'</code> filter, we can intercept the request for an url like the one above before is parsed by WordPres, and we can prevent WordPress to further process the url.</p>\n\n<pre><code>is_admin() or add_filter('do_parse_request', function($do, $wp) {\n\n // quick way to get current url\n $url = trim(esc_url_raw(add_query_arg(array())), '/');\n // check if WP has some subfolder in home url\n $path = trim(parse_url(home_url(), PHP_URL_PATH), '/');\n $path and $path .= '/';\n\n // this is not one of ours secret urls, just do nothing\n if (strpos($url, $path.'s/') !== 0) {\n return $do;\n\n // extract post id and nonce from url\n $sectretUrl = explode('|', preg_replace('~^'.$path.'s/~', '', $url), 2);\n $id = (int) base64_decode(urldecode($sectretUrl[0])) ;\n $nonce = empty($sectretUrl[1]) ? false : $sectretUrl[1];\n\n // verify nonce, if not valid let WordPress continue the flow\n // that very likely ends on a 404\n if (!$id || !$nonce || ! wp_verify_nonce($nonce, 'my-cpt'.$id)) {\n return $do;\n\n // everything ok, let's set query var and tell WP don't parse request\n $wp->query_vars = array('p' => $id);\n $wp->is_secret_ok = $id;\n return false;\n\n}, PHP_INT_MAX, 2);\n</code></pre>\n\n<p>That's it, it works.

And using an url like <code>\"http://example.com?p={$decoded_id}\"</code> that person will be able to view the post.</p>\n\n<p>Moreover, I guess that the title of the post is visible. If you use the slug that WordPress autogenerates, using an url like <code>\"http://example.com?p={$guessed_slug}\"</code> your post will be visible again.</p>\n\n<p>This means you need to prevent access to standard url for the CPT post. Maybe only allow privileged users, like administrators and editors.</p>\n\n<pre><code>add_action('template_redirect', function() {\n // when not our CPT or user is privileged, do nothing\n if (! is_singular('my-cpt') || current_user_can('edit_others_posts')) {\n return;\n }\n global $wp;\n // if this is from \"standard\" url, exit with error\n if (! isset($wp->is_secret_ok) || $wp->is_secret_ok !== (int) get_queried_object_id()) {\n wp_die('Not allowed.');\n }\n // prevent canonical redirect that will ends in a 404 request\n add_filter('redirect_canonical', '__return_false');\n}, -1);\n</code></pre>\n\n<p>To prevent access to users that comes from \"standard\" url, I used a variable <code>$wp->is_secret_ok</code> that I set in the previous code snippet, when the hashed url is verified.</p>\n\n<h1>Creating the secret CPT link</h1>\n\n<p>The url that we need is a bit complex, so we may want to create a function that builds it, taking as param the post ID.</p>\n\n<p>It is also possible to use that function to filter the permalink and let WordPress automatically output the \"secret\" url when you just call <code>the_permalink()</code>.</p>\n\n<p>Something like this:</p>\n\n<pre><code>function my_cpt_secret_url($postId) {\n $id = urlencode(base64_encode((string)$postId));\n\n return home_url('/s/'.$id.'|'.wp_create_nonce('my-cpt'.$postId));\n}\n\nis_admin() or add_filter('post_type_link', function($link, $post) {\n if ($post->post_type === 'my-cpt') {\n return my_cpt_secret_url($post->ID)\n return $link;\n}, 30, 2);\n</code></pre>\n"

Assuming you write a plugin and hook into [activation / deactivation](https://developer.wordpress.org/plugins/the-basics/activation-deactivation-hooks/) to [register\_post\_type](https://codex.wordpress.org/Function_Reference/register_post_type) is that good enough? Or do you need to do it every [init](https://codex.wordpress.org/Plugin_API/Action_Reference/init)?
I'm looking for perf boosts and I want to reduce unnecessary calls.
[GenerateWP](https://generatewp.com/post-type/) uses `add_action( 'init', 'custom_post_type', 0 );` so that might be as early as I might want to register it.

Use [add\_rewrite\_rule](https://codex.wordpress.org/Rewrite_API/add_rewrite_rule) or [add\_rewrite\_endpoint](https://codex.wordpress.org/Rewrite_API/add_rewrite_endpoint) to capture the `HASHorSOMETHINGcrazyANDrandom`.
[Hashids](http://hashids.org/php/) could also help you generate a hash that you could read back later.
```
$hashids = new Hashids\Hashids('this is my salt');
$post_id = 1;
$request_id = 2;
$random = 3;
$crazy_id = $hashids->encode($post_id, $request_id, $random);
$numbers = $hashids->decode($crazy_id);
```

**UPDATE #1**
This creates two endpoints:
>
> <http://example.com/CPT/>{CODE}/{HASH}
>
>
> <http://example.com/CPT/>{CODE}/
>
>
>
In either case a new hash will be generated with a new link everytime. Because I'm using `wp_hash_password` I loop until a password doesn't contain `/` so it won't break the URL. I'm sure there are better ways but... it works for this test. The plain password is based on the `SERVER_NAME` + `{CODE}` which was taken from the first param.
Each hash URL is unique but always validates if used with the correct code.

**UPDATE #2 | LIFETIME NONCE**
For @birgire - To make a lifetime nonce wouldn't you just need to remove the `wp_nonce_tick()` from [wp\_create\_nonce](https://core.trac.wordpress.org/browser/tags/4.4/src/wp-includes/pluggable.php#L1880)?
```
function wp_create_lifetime_nonce($action = - 1) {
$user = wp_get_current_user();
$uid = (int) $user->ID;
if( ! $uid) {
$uid = apply_filters('lifetime_nonce_user_logged_out', $uid, $action);
}
$token = wp_get_session_token();
$i = 0;//wp_nonce_tick(); -- time is not a factor anymore
return substr(wp_hash($i . '|' . $action . '|' . $uid . '|' . $token, 'nonce'), - 12, 10);
}
function wp_verify_lifetime_nonce($nonce, $action = - 1) {
$nonce = (string) $nonce;
$user = wp_get_current_user();
$uid = (int) $user->ID;
if( ! $uid) {
$uid = apply_filters('lifetime_nonce_user_logged_out', $uid, $action);
}
if(empty($nonce)) {
return false;
}
$token = wp_get_session_token();
$i = 0; //wp_nonce_tick(); -- time is not a factor anymore
// Nonce generated anytime ago
$expected = substr(wp_hash($i . '|' . $action . '|' . $uid . '|' . $token, 'nonce'), - 12, 10);
if(hash_equals($expected, $nonce)) {
return 1;
}
do_action('wp_verify_lifetime_nonce_failed', $nonce, $action, $user, $token);
// Invalid nonce

Replace your code with this code:-
```
add_action('wp_footer', 'myCssCode', PHP_INT_MAX);
function myCssCode() {
?>
<style>

I am looking for an option where a custom meta value will be saved when user uploads an attachment.
Lets say I need a meta key \_example\_meta\_key and want to save meta value of this as ex087659bh *(It will be a randomly generated number, I can take care of this.)*
The problem is, I can't seem to find any filters to add custom meta value on upload.
There are some tutorials which shows the way to add fields in media edit form but I need this to be executed at the time of file upload.

Use `added_post_meta` and `update_post_meta` with the `$post_id`. For extended properties see this [post](https://wordpress.stackexchange.com/a/212390/84219) and [this](https://wordpress.stackexchange.com/a/1065/84219) for more image functions.
```
add_action('added_post_meta', 'wpse_20151218_after_post_meta', 10, 4);
function wpse_20151218_after_post_meta($meta_id, $post_id, $meta_key, $meta_value) {
// _wp_attachment_metadata added
if($meta_key === '_wp_attachment_metadata') {
// Add Custom Field
update_post_meta($post_id, '_example_meta_key', 'ex087659bh');
// _wp_attached_file
// _wp_attachment_metadata (serialized)
// _wp_attachment_image_alt
// _example_meta_key
$attachment_meta = get_post_meta($post_id);
}

If a user is not logged in then [admin\_head](https://codex.wordpress.org/Plugin_API/Action_Reference/admin_head) probably won't run. So let's just check their [capabilities](https://codex.wordpress.org/Roles_and_Capabilities).

This code is used after `<head>` and before `<body>` and is supposed to get current page's slug. It works great, however it will get the *slug of first blog post* when on *"general"* blog page.
Example:
* Blog url: `www.my-site.com/blog/ ->` slug in admin area is set to `blog`
* Blog post url: `www.my-site.com/post-1/ ->` slug in admin area is set to `post-1`
Code echoes `post-1` for both. **Any ideas?**

`$post` is going to be set to the first post in the Loop when the page loads. On "page" pages with only one post in the Loop that is going to be the page data you expect. On archive pages it will be the first post in the set of posts on the page. This is what appears to be happening. You can't trust `$post` explicitly like that-- that is, without understanding exactly when it is set to what. (Most loops, even secondary ones, will alter this variable as well)
To get the page data itself you need `get_queried_object()` but be careful with that too as it will be different on various types of pages-- sometimes a post object, sometimes a user object, sometimes `null`.

Adding ignore sticky line inside array should solve the issue :)
```
$args = array(
'post_type' => 'post',
'posts_per_page' => '6',
'ignore_sticky_posts' => 1,//this is the one :)
'paged' => $paged,
);
```

<p>I need get all comments of a post including of the meta value..
for eg. i need all comments fields + a meta value.</p>
<p>i tried the following code to get but.. its not working</p>
<pre><code>$args = array(
'status' => 'approve',
'type' => 'comment',
'post_id' => '99',
'post_type' => 'product',
//'count' => true,
'meta_query' => array(
array(
'key' => 'comment_rating_avg_key',
'compare' => 'EXISTS',
),
),
);
$comments_query = new WP_Comment_Query;
$comments = $comments_query->query( $args );
var_dump($comments);
</code></pre>
<p>Do i need to write a custom query to get it ?
or it can be done using default WP functions ?</p>

[`WP_Comment_Query`](https://codex.wordpress.org/Class_Reference/WP_Comment_Query) doesn't pull comment meta. You can search by comment meta but the query doesn't return that data. You could easily check this yourself by looking at the Codex.
You need to loop over the results and run [`get_comment_meta()`](https://codex.wordpress.org/Function_Reference/get_comment_meta), or essentially do the same via a filter on [`the_comments`](https://core.trac.wordpress.org/browser/tags/4.4/src/wp-includes/class-wp-comment-query.php#L438).
It is also possible to add to the data returned by [filtering the "fields" clauses](https://core.trac.wordpress.org/browser/tags/4.4/src/wp-includes/class-wp-comment-query.php#L810):
```
function add_cmeta_wpse_212423($clauses){
// var_dump($clauses);
global $wpdb;
$meta = "(SELECT meta_value
FROM {$wpdb->commentmeta}
WHERE (
comment_id = comment_ID
AND meta_key = 'test_comment_meta')
) as test_comment_meta";
$clauses['fields'] .= ', '.$meta;
return $clauses;
}
add_filter('comments_clauses','add_cmeta_wpse_212423');
```
I created a subquery. You could create a `JOIN` as well.

<pre><code><?php
$query = new WP_Query( array('post_type' => 'portfolio', 'posts_per_page' => 7, 'order' => ASC ) );
while ( $query->have_posts() ) : $query->the_post();

"text": "<p>I'm not going to discuss implementation of a slider, that is too broad. There are a couple of tutorials around which you can look at on how to implement simple sliders</p>\n\n<p>The real issue here is the query itself. Sorting a query by the terms a post belongs to is quite heavy operations, and if not done correctly (<em>no offense, as you have done in your answer</em>), it can be really really expensive. The overly-used method of getting all terms and then looping through them and running a query for each term can have you stuck at an operation making 100 db calls, and that is only on a small site with only a few terms and posts. Very large sites can pack the meat on db calls which can see your SEO rating stuck at minus and page load times deep in the red.</p>\n\n<p>I have done a <a href=\"https://wordpress.stackexchange.com/search?tab=newest&q=usort%20user%3A31545\">few posts on this specific subject</a>, so I actually wanted to mark this as duplicate, but I feel that this needs a fresh look with a different approach.</p>\n\n<p>What I have done in the passed is to do everything (<em>query all the posts, then sort the result and displaying them</em>) in one single operation. This complete query result was then stored in a transient. The setback here is that we store a tremendous amount of serialized data in the transient which again is not really what transients should do.</p>\n\n<p>What I will do here is to build a dynamic sorting script which will do all the hard work and will store only post ID's in a transient (<em>this will take care of not having to store huge amounts of serialized data which can be slow</em>). We will then use the sorted post ID's from the transient to get our posts that we will need. Because posts are saved in a cache, we do not hit the db hard to get our desired posts, we simply query and return the posts from the cache if they are already there</p>\n\n<h2>FEW IMPORTANT NOTES:</h2>\n\n<ul>\n<li><p>Although I have tested the code, it is not fully tested. On my install there are no obvious bugs at this stage. You should however test this fully with debug turned on on a local test install before moving this to production</p></li>\n<li><p>For what it is worth, the code need at least PHP5.4, but you are already on at least PHP5.6, or even better, PHP7 ;-)</p></li>\n<li><p>There are a few <code>orderby</code> parameters that is not excepted by the code. You can extend it if needed. Check the post search I have linked to.

I have a taxonomy called `portfolio_cat` with its categories.So now I need to create a slider with that categories as a title and their post items. How I can do that? What loop do I need to have so that I could put in a slider categories with their posts?
I dont know how to customize this loop to fit in
```
<?php
$query = new WP_Query( array('post_type' => 'portfolio', 'posts_per_page' => 7, 'order' => ASC ) );
while ( $query->have_posts() ) : $query->the_post();
?>
```

I'm not going to discuss implementation of a slider, that is too broad. There are a couple of tutorials around which you can look at on how to implement simple sliders
The real issue here is the query itself. Sorting a query by the terms a post belongs to is quite heavy operations, and if not done correctly (*no offense, as you have done in your answer*), it can be really really expensive. The overly-used method of getting all terms and then looping through them and running a query for each term can have you stuck at an operation making 100 db calls, and that is only on a small site with only a few terms and posts. Very large sites can pack the meat on db calls which can see your SEO rating stuck at minus and page load times deep in the red.
I have done a [few posts on this specific subject](https://wordpress.stackexchange.com/search?tab=newest&q=usort%20user%3A31545), so I actually wanted to mark this as duplicate, but I feel that this needs a fresh look with a different approach.
What I have done in the passed is to do everything (*query all the posts, then sort the result and displaying them*) in one single operation. This complete query result was then stored in a transient. The setback here is that we store a tremendous amount of serialized data in the transient which again is not really what transients should do.
What I will do here is to build a dynamic sorting script which will do all the hard work and will store only post ID's in a transient (*this will take care of not having to store huge amounts of serialized data which can be slow*). We will then use the sorted post ID's from the transient to get our posts that we will need. Because posts are saved in a cache, we do not hit the db hard to get our desired posts, we simply query and return the posts from the cache if they are already there
FEW IMPORTANT NOTES:
--------------------
* Although I have tested the code, it is not fully tested. On my install there are no obvious bugs at this stage. You should however test this fully with debug turned on on a local test install before moving this to production
* For what it is worth, the code need at least PHP5.4, but you are already on at least PHP5.6, or even better, PHP7 ;-)
* There are a few `orderby` parameters that is not excepted by the code. You can extend it if needed. Check the post search I have linked to. I have done a lot of different stuff with `usort()`
* The code uses the first term returned by `get_the_terms`, so posts with multiple terms might be sorted incorrectly due to the first term being used
THE SORTING SCRIPTS:
--------------------
What we will do is, we will get all the posts according to our needs, but we will only return the post object properties we need to save resources. We will then use `usort()` to sort the posts according to terms. Instead of creating something static that you will need to alter when needed, we will make this dynamic so you can reuse it as much as you like by only changing the values of the parameters passed

I have commented the code to make it easy to follow. A few notes on the parameters though
* `$taxonomy`. This is the taxonomy to get terms and posts from
* `$args`. An array of any valid argument that is acceptable in [`WP_Query`](https://codex.wordpress.org/Class_Reference/WP_Query). There are a few defaults set,
```
$defaults = [
'posts_per_page' => -1,
'order' => 'DESC',
'orderby' => 'date'
];
```
so you can use this parameter to set any extras like 'post\_type' and a `tax_query` if you need more specific posts
* `$term_args`. An array of parameters valid with `get_terms`. This is used to get more spefic terms from $taxonomy.
* `$sort` An array of arguments used to determine the sort order in `usort()`. Valid arguments are `order` and `orderby`
Remember, if you do not need to set a parameter and you need to set one adjacent, pass an empty array, except for `$taxonomy` which must be set to a valid taxonomy
EXAMPLE
-------
```
$taxonomy = 'my_taxonomy';
$args = [
'post_type' => 'my_post_type'
];
$term_args = [];
$sort = [
'order' => 'DESC'
];
$q = get_sorted_query_results( $taxonomy, $args, $term_args, $sort );
```
This, on my install runs 3 db queries in +/- 0.002 seconds.
We have save all the relevant sorted post ID's in a transient which expires every 30 days. We need to flush it as well when we publish a new post, update, delete or undelete a post. Very generically, you can make use of the `transition_post_status` hook to flush the transient on the above cases
```
add_action( 'transition_post_status', function ()
{
global $wpdb;
$wpdb->query( "DELETE FROM $wpdb->options WHERE `option_name` LIKE ('_transient%_pobt_%')" );
$wpdb->query( "DELETE FROM $wpdb->options WHERE `option_name` LIKE ('_transient_timeout%_pobt_%')" );
});
```
There are quite a [lot of examples on site with specific uses](https://wordpress.stackexchange.com/search?q=transition_post_status) to target specific post status changes. You also have the post object available, so you can target specific post types, authors, etc
Now that you have an array of sorted id's you can now query complete posts. Here we would use the `post__in` parameter and as `orderby` value to return the desired posts already sorted
From the above example, we would do
```
if ( $q ) { // Very important check to avoid undesired results if $q is empty
$query_args = [
'post__in' => $q,
'order' => 'ASC',
'orderby' => 'post__in',
// Any other parameters
];
$query = new WP_Query( $query_args );
// Run your loop, see code below
}
```
All we need to do now is to display the terms names as headings. This is quite simple, compare the current post term with the previous post's term, if they do not match, display term name, otherwise, display nothing
```
if ( $query->have_posts() ) {
// Define variable to hold previous post term name
$term_string = '';
while ( $query->have_posts() ) {
$query->the_post();
// Get the post terms. Use the first term's name
$term_name = get_the_terms( get_the_ID(), 'TAXONOMY_NAME_HERE' )[0]->name;
// Display the taxonomy name if previous and current post term name don't match
if ( $term_string != $term_name )
echo '<h2>' . $term_name . '</h2>'; // Add styling and tags to suite your needs
// Update the $term_string variable
$term_string = $term_name;
// REST OF YOUR LOOP
}
wp_reset_postdata();
}
```
Here is the complete query as I have run it on my install
```
$taxonomy = 'category';
$args = [
'post_type' => 'post'
];
$term_args = [];
$sort = [
'order' => 'DESC'
];
$q = get_sorted_query_results( $taxonomy, $args, $term_args, $sort );
if ( $q ) { // Very important check to avoid undesired results if $q is empty
$query_args = [
'posts_per_page' => count( $q ),
'post__in' => $q,
'order' => 'ASC',
'orderby' => 'post__in',
// Any other parameters
];
$query = new WP_Query( $query_args );
if ( $query->have_posts() ) {
// Define variable to hold previous post term name
$term_string = '';
while ( $query->have_posts() ) {
$query->the_post();
// Get the post terms. Use the first term's name
$term_name = get_the_terms( get_the_ID(), 'category' )[0]->name;
// Display the taxonomy name if previous and current post term name don't match
if ( $term_string != $term_name )
echo '<h2>' . $term_name . '</h2>'; // Add styling and tags to suite your needs
// Update the $term_string variable
$term_string = $term_name;
// REST OF YOUR LOOP
the_title();
}
wp_reset_postdata();
}
}
```
On test with 21 posts and 6 categories, the whole operation cost me 7 queries in 0.1 seconds
With the overly-used easy method
```
$terms= get_terms( 'category' );
foreach ( $terms as $term ) {
echo $term->name;
$args = [
'tax_query' => [
[
'taxonomy' => 'category',
'terms' => $term->term_id,
]
],
];
$query = new WP_Query( $args );
while ( $query->have_posts() ) {
$query->the_post();
the_title();
}
wp_reset_postdata();
}
```
I got **32** queries in 0.2 seconds. That is 25 queries (*5times more*) more, and that is only on 6 categories and 21 posts.

I recently had a system crash and had to reinstall WordPress with my backup files.
In the JavaScript log I began throwing errors pertaining to the domain and realized I was still using the remote servers URL. So, I read the *Changing the Site URL* article in the WP Codex and added the following two lines to my `config.php` file:
```
define('WP_SITEURL','http://localhost:3000');
define('WP_HOME','http://localhost:3000');
```
If I go to *localhost:3000* in my browser, it goes instead to *localhost* and loads the Apache server *It works!* page. However, I am using PHPs built in server. So please don't drag Apache into this.
I do have the ability to go to *localhost:3000/wp-admin* and login with admin credentials, however when I try to click any of the admin links, I get a 404 not found:

Instead of renaming, set up your local web server to handle requests to that domain and modify your local hosts file to associate the domain with ip 127.0.0.1.
Especially when debugging hard to find bugs you will want your enviroment to be as similar to the one of the live site.
(I can do it in a not very modern version of WAMP and therefor I assume you can do it with all similar web servers)

Am I missing something?

I'm not sure I fully understand your question, but to add some HTML (just *over* or *under* the submit field) that is visible to both *logged-in* and *logged-out* users, you can try the following:
```
add_filter( 'comment_form_submit_field', function( $submit_field )
{
//-----------------------------------
// Adjust the prepend to your needs
//-----------------------------------
$prepend = '<p> Prepend some HTML </p>';
//-----------------------------------
// Adjust the append to your needs
//-----------------------------------
$append = '<p> Append some HTML </p>';
return $prepend . $submit_field . $append;
} );
```
Other workarounds are possible, like the `comment_form` action.
There are some comment-form filters that are only available to *logged-out* users, like the
* `comment_form_before_fields`
* `comment_form_field_{$name}`
* `comment_form_after_fields`
So most likely you're trying to hook into those filters - but you haven't mentioned what filters you're using.

<p>I've used Advanced Custom Fields to create custom fields for Competition name, answers etc. I've made a custom post type for competitions as shown on the image and I used Wordpress functions.php to create the columns from my custom fields values. </p>
<p>I'm trying to get a "Filter by"-dropdown box with the competitions different names/labels like shown below, but I can only find solutions using taxonomies, which I rather not use <strong>if possible</strong> because I've only used custom fields for everything else.</p>
<p>Is it possible to make a custom "Filter by" dropdown using only custom fields?</p>

I've used Advanced Custom Fields to create custom fields for Competition name, answers etc. I've made a custom post type for competitions as shown on the image and I used Wordpress functions.php to create the columns from my custom fields values.
I'm trying to get a "Filter by"-dropdown box with the competitions different names/labels like shown below, but I can only find solutions using taxonomies, which I rather not use **if possible** because I've only used custom fields for everything else.
Is it possible to make a custom "Filter by" dropdown using only custom fields?
[](https://i.stack.imgur.com/2qP4Y.png)
|
And for displaying result for Filter then try this code
```
add_filter( 'parse_query', 'prefix_parse_filter' );
function prefix_parse_filter($query) {
global $pagenow;
$current_page = isset( $_GET['post_type'] ) ? $_GET['post_type'] : '';
if ( is_admin() &&
'competition' == $current_page &&
'edit.php' == $pagenow &&
isset( $_GET['competition-name'] ) &&
$_GET['competition-name'] != '' ) {
$competition_name = $_GET['competition-name'];
$query->query_vars['meta_key'] = 'competition_name';
$query->query_vars['meta_value'] = $competition_name;
$query->query_vars['meta_compare'] = '=';
}
}
```
Change the meta key and meta value as required.
I have taken "competition name as meta\_key and "competition-name" as select drop down name.

Hello there for a custom post type "organizations" I have about 5000 posts which have to be shown in a list with link within one page.
However WP\_Query just crashes (without PHP timeout just after 4 seconds on the server). Is this a WordPress problem? If so, why do they limit it? Or is it definitly a server problem?
```
$q = new WP_Query(array('post_type' => 'organization','posts_per_page' => 9999));
```

Querying this many posts is dangerous and you can ( and do ) take the site down. If you absolutely have to do this, you need to adjust your query to be more performant.
If you're just needing the link then add `'fields' => 'ids'` to your params - this will only return the post ID and not the whole Post object. You can then use the ID to get the permalink, title etc.
If you're not going to paginate, then use `'no_found_rows' => true` this will stop WordPress from running expensive SQL CALC queries to get the total number of posts that the query retrieves.
You should 100% cache the results of this query using the [Transient API](https://codex.wordpress.org/Transients_API) this will allow you to return cached HTML instead of rebuilding this query every time someone hits the page.

<p>I have 3 headers (header.php, header2.php, and header3.php). I want to always display header.php at the top. Below header.php, I want a second header to display depending on what category the post is. If the post is Grizzly Bears, I want header2. If the post is Peace Pipes, I want header3.</p>
<p>I understand displaying 2 headers with: </p>
<pre><code><?php
get_header();
get_header(header2);
?>
</code></pre>
<p>But how can I make the second header dependent on if a category is tagged (or tag is added, to make this question complete)? </p>
<p><strong>EDIT:</strong> <em>Due to the help of jgraup and karpstrucking, I see this question is not complete:</em></p>
<p>Using ...</p>
<pre><code>if ( has_category( 'Grizzly Bears' ) ) {
get_header( 'header2' );
} else if ( has_category( 'Peace Pipes' ) ) {
get_header( 'header3' );
}
</code></pre>
<p>... works only if the has_category is the child-most category. I would like to apply the condition to the parent-most category. This code fails for this. For example, I check parent category 'Grizzly Bears' and child category 'Grizzly Bears Fishing' and I can't use the code for 'Grizzly Bears'.</p>

You can use the [has\_category()](https://codex.wordpress.org/Function_Reference/has_category) function for this:
```
if ( has_category( 'Grizzly Bears' ) ) {
get_header( 'header2' );
} else if ( has_category( 'Peace Pipes' ) ) {
get_header( 'header3' );
}
```
You can add the [has\_tag](https://codex.wordpress.org/Function_Reference/has_tag) function as well. Both accept an array of term IDs, names or slugs if you want to check multiples at once.
Edit: changed `in_category` to `has_category` for consistency and potential future deprecation

How can I display the taxonomy terms the way they are hierarchical?
|
I solved it using simple PHP, and with the help of my colleague Mr. Afzal. My existing query was:
```
$all_terms = get_categories( array(
'taxonomy' => 'my_tax',
'show_count' => true,
'hide_empty' => false,
'orderby' => 'term_group', //bogus :p
) );
```
Instead of my existing query, I made it a `$wpdb` query for a better control:
```
global $wpdb;
$tax_query = $wpdb->get_results("SELECT t.*, tt.* FROM $wpdb->terms AS t
INNER JOIN $wpdb->term_taxonomy AS tt ON t.term_id = tt.term_id
WHERE tt.taxonomy IN ('my_tax')
ORDER BY tt.parent, t.name ASC
", ARRAY_A);
```
So that we now have *alphabetically* sorted array with some valuable information that I need for further proceedings:
* `term_id`
* `parent`
### Hierarchical Arrays
I made my tree-generating function using [this SO thread](https://stackoverflow.com/a/10332361/1743124), it's a recursive function:
```
function create_tax_tree( &$list, $parent ) {
$taxTree = array();
foreach( $parent as $ind => $val ) {
if( isset($list[$val['term_id']]) ) {
$val['children'] = create_tax_tree( $list, $list[$val['term_id']] );
}
$taxTree[] = $val;
}
return $taxTree;
}
```
And this function will make me an array with exact parent-child relationship. After my db Query, I did the following now:
```
if (count( $tax_query ) > 0) :
//Making my tree array
$taxs = array();
foreach( $tax_query as $tax ) {
$taxs[ $tax['parent'] ][] = $tax;
}
//that's my tree in array or arrays
$tax_tree = create_tax_tree( $taxs, $taxs[0] );
else :
_e('No term found', 'textdomain');
endif;
```
Now my tree is in `$tax_tree` variable. If I `var_dump($tax_tree)`, it's an array of arrays, which is full of exact parent-child relations.
### Final results
To get the final result, we need another recursive function, and here PHP5 provides a [nice bunch of classes](http://php.net/manual/en/spl.iterators.php), learned from [this SO thread](https://stackoverflow.com/a/5524267). I'm using two of them in the following way:
```
$tax_iterator = new RecursiveIteratorIterator(new RecursiveArrayIterator( $tax_tree ));
foreach( $tax_iterator as $key => $value ) {
$depth = get_tax_depth( $term_id, true ); //custom-made function
if( 'term_id' === $key )
$term_id = (int) $value; //having the term_id for further use
if( 'name' === $key ) {
echo '<p>';
$pad = str_repeat('---', $depth * 3); //for visual hierarchy
echo $pad .' '. $value; //the name of the tax term
echo '</p>';
}
}
```
And the output is:
```
Level 0
-- Level 1
--- Level 2
---- Level 3
--- Level 2
---- Level 3
---- Level 3
-- Level 1
--- Level 2
```

'wpautop' => true, // Default
'textarea_rows' => 15,
'tinymce' => array(

```
function foo() {
echo 'bar';

I'm aware of `_deprecate_function()` but would be grateful for an example showing all the steps I should take in order to remove the function from my plugin's core.
Ref: <https://developer.wordpress.org/reference/functions/_deprecated_function/>

In addition to the answer by @Welcher:
There are some good "*graveyard*" examples in the core, where "*[functions come to die](https://github.com/WordPress/WordPress/blob/c1976fff71ad8f56ffe1e22facb9668ea6b5082b/wp-includes/deprecated.php#L11-L13)*".
You could use them as guidelines, e.g. regarding the documentation.
Here's one such example for the `permalink_link()` under the [`wp-includes/deprecated.php`](https://github.com/WordPress/WordPress/blob/c1976fff71ad8f56ffe1e22facb9668ea6b5082b/wp-includes/deprecated.php#L835-L845)
```
/**
* Print the permalink of the current post in the loop.
*
* @since 0.71
* @deprecated 1.2.0 Use the_permalink()
* @see the_permalink()
*/
function permalink_link() {
_deprecated_function( __FUNCTION__, '1.2', 'the_permalink()' );
the_permalink();
}
```
Here's the inline documentation for the [`_deprecated_function`](https://github.com/WordPress/WordPress/blob/c1976fff71ad8f56ffe1e22facb9668ea6b5082b/wp-includes/functions.php#L3532) function that explains the input arguments:
```
/**
* Mark a function as deprecated and inform when it has been used.
*
* There is a hook deprecated_function_run that will be called that can be used
* to get the backtrace up to what file and function called the deprecated
* function.
*
* The current behavior is to trigger a user error if WP_DEBUG is true.
*
* This function is to be used in every function that is deprecated.
*
* @since 2.5.0
* @access private
*
* @param string $function The function that was called.
* @param string $version The version of WordPress that deprecated the function.
* @param string $replacement Optional. The function that should have been called.
* Default null.

In your second code block change
```

to
```

This should solve your problem :)

```

```
I want to replace id="menu-item-27" with id="nava".
Any help is much appreciated!

You could use the `nav_menu_item_id` filter like this:
```
add_filter( 'nav_menu_item_id', function( $menu_id, $item, $args, $depth )
{
if( 'menu-item-27' === $menu_id )
$menu_id = 'nava';
return $menu_id;
}, 10, 4 );
```
but I this is "unstable" regarding the menu ID, if you delete and re-insert menu items. You might also want to target a specific menu location.
A common method, that I like for it's flexibility, is to check for a specific CSS classes, that we can set within the navigational UI in the backend.
Here's an example where we check for the `set-id-nava` class. If it is set, then we override the CSS id with `nava`:
```
add_filter( 'nav_menu_item_id', function( $menu_id, $item, $args, $depth )
{
if( in_array( 'set-id-nava', (array) $item->classes ) )
$menu_id = 'nava';
return $menu_id;
}, 10, 4 );
```
We could also make this more dynamically and check for `set-id-???`.
We could even add an extra input field to set CSS id's for each menu item. But that would require more work.
If you don't want the `set-id-nava` as a CSS class, then you could remove it, e.g. via the `nav_menu_css_class` filter.

When I add a new user with a different email address, I get the error message: That username is currently reserved but may be available in a couple of days.
For me, I removed the row from the database in the table wp\_signups where user\_login equaled the username. Essentially:
```
delete from wp_signups where user_login = 'abc';
```
Then I was able to re-add the user.
Edit suggestion by @aubreypwd:
Additionally, admins (network admins only in an MU or network install) have the option to add users without sending an email. If you check that option, it avoids this process.

<p>I have a website hosted on ASP.NET server and using wordpress to build my site. I've extended its functionalities using PHP code. At which directory do I store secure files such as (passwords and certificate.pem)?</p>
<p>My server has the following structure:</p>
<pre><code>-/
-/mywebsite.com
-/data
-/logs
-/wwwroot
-/wp-admin
-/wp-content
-/wp-includes
</code></pre>
<p>I understand that ASP.NET has a file called web.config file that is secure and stored at <code>wwwroot</code>. What's something equivalent using PHP? It is also my understanding that Wordpress stored database password in wp-config.php located at <code>wwwroot</code> so I assume <code>wwwroot</code> is a secure directory?</p>
<p>I'm using a shared host btw.</p>
<p>Thanks.</p>

I have a website hosted on ASP.NET server and using wordpress to build my site. I've extended its functionalities using PHP code. At which directory do I store secure files such as (passwords and certificate.pem)?
My server has the following structure:
```
-/
-/mywebsite.com
-/data
-/logs
-/wwwroot
-/wp-admin
-/wp-content
-/wp-includes
```
I understand that ASP.NET has a file called web.config file that is secure and stored at `wwwroot`. What's something equivalent using PHP? It is also my understanding that Wordpress stored database password in wp-config.php located at `wwwroot` so I assume `wwwroot` is a secure directory?
I'm using a shared host btw.

<p>I have a function in functions.php which automatically generates a page. It doesn't check to see if there is already a page with the same title at the moment.</p>

`after_setup_theme` is not the hook you are looking for - you want [`after_switch_theme`](https://codex.wordpress.org/Plugin_API/Action_Reference/after_switch_theme) - this hook will only run once, when your theme is initally activated.

[`get_the_permalink()`](https://developer.wordpress.org/reference/functions/get_the_permalink/) doesn't `echo` anything. It just returns a string so that you can further manipulate it.
You need [`the_permalink()`](https://developer.wordpress.org/reference/functions/the_permalink/) instead, which will `echo` the link.
The difference used to be clear in the Codex but now, in the much inferior, "developer" code reference toward which WordPress is migrating it is not so clear.

<pre><code>global $wpdb;
$min_posts = 1;
$author_ids = $wpdb->get_col("SELECT `post_author` FROM
(SELECT `post_author`, COUNT(*) AS `count` FROM {$wpdb->posts}
WHERE `post_status`='publish' GROUP BY `post_author`) AS `stats`
WHERE `count` >= {$min_posts} ORDER BY `count` DESC;");
</code></pre>
<p>But I have two issues: how can I choose to display it on a particular page (I usually add snippets to functions.php) and how can I get the emails instead of the iDs ? </p>
<p>I probably have to use <code>get_the_author_meta( 'user_email' )</code> but I don't know how to implement it here. </p>
<p>Thanks for your time and help</p>

You can place following code in your functions.php file & use the shortcode `[myblogwriters min_posts="1"]` anywhere in the page/post content and can also change the min\_posts value :)
```
function show_min_one_post_writers($atts){
global $wpdb;
$attrs = shortcode_atts( array(
'min_posts' => ''
), $atts );
$min_posts = $attrs['min_posts'];
$authors = $wpdb->get_col("SELECT `post_author` FROM
(SELECT `post_author`, COUNT(*) AS `count` FROM {$wpdb->posts}
WHERE `post_status`='publish' GROUP BY `post_author`) AS `stats`
WHERE `count` >= {$min_posts} ORDER BY `count` DESC;");
$my_blog_writers = "";
if ( empty ($authors) ) {
return "<p>No one has contirbuted any post yet!</p>";
} else {
foreach ($authors as $author_id) {
$my_writer = get_userdata($author_id);
$my_blog_writers .= "<p>".$my_writer->first_name ." ".$my_writer->last_name ." : ". $my_writer->user_email."</p>";

<p>I am currently creating a post programmatically, with the <code>wp_insert_post</code> function but am having some difficulties when adding two variables into the content part of the array. I would like to add <code>$_POST['poll-description']</code> as well as the code I am currently using <code>'[poll id=' . $latest_pollid . ']'</code> to be the post content.</p>
<p>Is there any way I can use both of these in the following code?</p>
<pre><code>$post_id = wp_insert_post(
array(
'comment_status' => 'open',
'ping_status' => 'closed',
'post_author' => $current_user->ID,
'post_name' => $slug,
'post_title' => $pollq_question,
'post_status' => 'publish',
'post_type' => 'post',
'post_content' => '[poll id=' . $latest_pollid . ']'
)
);
</code></pre>
<p>Would this work?</p>
<pre><code>`post_content' => $_POST['poll-description'] '[poll id=' . $latest_pollid . ']'`

It can be done with a custom field and the CSS should be changed to `.php` file:
```
$image = get_post_meta( $post->ID, "ImagePathFromCustomField", true );
if ( $image != '' ) {
?>
<style type="text/css">
.bg-image {

I'm looking to add some client-side (JavaScript) events to the post edit screen of wp-admin (`post.php?action=edit`). I wish to fire events when the user selects a new featured image and a different event when they remove the featured image.
So far I've been able to find [this wordpress.se answer](https://wordpress.stackexchange.com/questions/175790/run-script-after-clicking-set-featured-image-in-media), which has allowed me to hook into the *"on featured image set"* event, however I'm at a loss as to how to hook into the *"on featued image removed"* event, as it pertains to the client.
I've dug into `wp.media.featuredImage.frame().states._events` a little bit using Chrome's WebInspector, but there doesn't seem to be an event registered that quite matches what I'm looking for...

So I was able to achieve what I wanted, albeit in a bit of a roundabout way. I'll share my solution here in case anyone stumbles across this post looking to do something similar.
Rather than adding an event listener to some unset event (that doesn't exist) on the object returned by `wp.media.featuredImage.frame()`, I instead added my own onclick event listener to the `#remove-post-thumbnail` link element. This feels a little hacky to me, since its not *directly* tied to the unset of a featured image, however since there's no prompt to verify removal, the user interaction is fairly seemless.
There is a caveat with this solution, however - there is already an `onclick` event bound to that link, so you need to avoid overriding that, or else you won't be able to actually remove the featured image. Originally I tried capturing that default onclick event and then calling it from within my own event that overrides it, like so:
**DO NOT DO THIS**
```
var ogCallback = document.getElementById('remove-post-thumbnail').onclick;
document.getElementById('remove-post-thumbnail').onclick = function(e) {
// My code - do some things
// ...
ogCallback(e);
}
```
But this made WordPress a little buggy when removing the featured image, likely due to some JavaScript scoping that I wasn't taking into account. Because I'm also leveraging jQuery (this is a judgment-free zone, right?) I was able to use jQuery's event binding system instead, and avoid overriding the default behaviour, allowing my custom code to run in tandem with WordPress' featured image removal logic:
**DO THIS**
```
$(document).on('click', '#remove-post-thumbnail', function(){
// Do stuff. Don't let your dreams be dreams

Don't ask why. Image below pretty much ask what I'm looking to achieve:
|
We could hook into the `after_wp_tiny_mce` with some CSS to hide it, if the `wplink` editor plugin is loaded.
**Example:**
```
add_action( 'after_wp_tiny_mce', function( $settings )
{
// Check for the 'wplink' editor plugin
if( isset( $settings['content']['plugins'] )
&& false !== strpos( $settings['content']['plugins'], 'wplink' )
)
echo '<style>
#link-selector > .howto, #link-selector > #search-panel { display:none; }
</style>';
} );
```

<p>I have an issue I can't solve. When my website loads it seems to be grabbing an old version of our customized CSS and using that to override all our new CSS. But that old version no longer exists. I have no idea where it's coming from.</p>
<p>If you look at our page source here: <a href="http://view-source:http://www.universaltheosophy.com/" rel="nofollow">view-source:http://www.universaltheosophy.com/</a> then scroll down and you'll see a bunch of css code, some of which I have no idea where it's coming from. After this:</p>
<pre><code>/*----------------------------------
* end review
----------------------------------*/
</code></pre>
<p>You'll see stuff like this:</p>
<pre><code>#navigation .inner {
width: 1250px !important;
}
</code></pre>
<p>I have no idea how to find out where this code is coming from. It's not in any of the CSS files under our theme's directory. I also tried turning off and disabling "wp supercache" after deleting the whole cache, thinking maybe the css was cached somewhere, but that did nothing. I've done a "string search" through the whole wordpress directory and can't find this css code anywhere!</p>
<p>The thing is, this css code <em>was</em> part of an old version of our customized CSS. We have a file called "custom-overrides-2.css" that is added to our theme's css files, which provides certain overrides. There was a previous version "custom-overrides-1.css", which I think contained the above css, but it's long since been deleted.</p>
<p>How can I find out where this code is coming from, and how do I get rid of it? It's completely f*ing up our mobile display, since our mobile "responsive.css" is being overridden by it.</p>
<p>Any help would be very much appreciated.</p>

<p>I have WordPress site 1 on domain1.com.</p>
<p>I copied WordPress site 1 to WordPress site 2 on domain2.com (database and files).</p>
<p>Both WordPress sites have their independent database names/usernames/passwords and separate FTP credentials/directories.</p>
<p>Both WordPress sites are on the same server (localhost).</p>
<p>When I delete a plugin/theme from WordPress site 2, that plugin/theme also gets deleted from WordPress site 1 (and vice versa)! Likewise, when I install a new plugin/theme on one of the sites, it also gets installed on the other site!</p>
<p>However, if I activate a plugin/theme on one site, it does not get activated on the other site. Also, if I add/delete a post/page/media file from one site, it does not get added/deleted to the other site.</p>
<p>Does anyone have any idea what is going on? I made sure there are no references in database 2 to database 1, and I even hardcoded the siteurl into wp-config.php</p>
<pre><code>define('WP_SITEURL', 'http://' . $_SERVER['HTTP_HOST']);
</code></pre>
<p>I'm still having this problem after three hours of deleting the database/files and re-uploading them. I even tried creating WordPress site 2 on entirely different FTP directories with new credentials (and likewise a new database and credentials) to no avail!</p>
<p>EDIT:</p>
<p>It gets even crazier. I completely deleted WordPress site 2's database and all files. I then did a completely NEW WordPress install, and when I click on Plugins, I see all the plugins that are on WordPress site 1 (likewise for themes)! The problem somehow still exists! Now I am completely stumped.</p>
<p>I'm on an Ubuntu server running Nginx.</p>

Still if its something like client requirement then below is somewhat **hack** sort of solution. Add this code to your `add_meta_box()` function. For the sake of understanding, below I have provided complete function but you will need to use selective code :-) Do let me know how it goes.
```
function myplugin_add_meta_box() {
$screens = array( 'post', 'page' );
foreach ( $screens as $screen ) {
add_meta_box(
'testdiv',
__( 'My Post Section Title', 'myplugin_textdomain' ),
'myplugin_meta_box_callback',
$screen,
'side'
);
}
/* Get the user details to find user id for whom this order should be shown. Ideally, I believe it will be admin user. Make sure you change the email id*/
$user = get_user_by( 'email', '[email protected]' );
$order = get_user_option("meta-box-order_post", $user->ID);
$current_order = array();
$current_order = explode(",",$order['side']);
for($i=0 ; $i <= count ($current_order) ; $i++){
$temp = $current_order[$i];
if ( $current_order[$i] == 'testdiv' && $i != 1) {
$current_order[$i] = $current_order[1];
$current_order[1] = $temp;
}
}
$order['side'] = implode(",",$current_order);
update_user_option($user->ID, "meta-box-order_page", $order, true);
update_user_option($user->ID, "meta-box-order_post", $order, true);
}
add_action( 'add_meta_boxes', 'myplugin_add_meta_box', 2 );

I am following [This tutorial](http://www.wpbeginner.com/wp-tutorials/how-to-install-and-setup-wordpress-multisite-network/) to Create a Network of WordPress Sites . After adding
```
/* Multisite */
define( 'WP_ALLOW_MULTISITE', true );
```
to my `wp-config.php` file and when I start to configure multisite network I got this error
```
ERROR: You cannot install a network of sites with your server address.
You cannot use port numbers such as :8080
```
I try to change
```
Listen 0.0.0.0:8080
Listen [::0]:8080
```
to
```
Listen 0.0.0.0:80
Listen [::0]:80
```
from `httpd.conf` of Apache but due to this wamp server remains orange .
How to solve this .I am a new to WordPress Any help would be highly appreciated .

**Warning: This is just a test for dev installs and not production sites**
I was curious to see if there was a workaround, for those who want to develope multisites on their dev installs but on different ports than `:80` and `:443`, e.g. `:8080`.
I only found this [blog post](http://benohead.com/wordpress-running-multisite-different-port/) by Henri Benoit. There he gives examples how to modify the 3.9.1 core, to get around the core restrictions.
Here's a *must-use* plugin `/wp-content/mu-plugins/wpse-ms-on-different-port.php` where we try to avoid core modifications:
```
<?php
/**

*
* Here we assume that the 'siteurl' and 'home' options contain the :8080 port

* WARNING: Not suited for production sites!
*/
/**

* strips out the semicolon (:) in the $domain string
* This means created sites with hostnames of

*/
add_filter( 'sanitize_user', function( $username, $raw_username, $strict )
{
// Edit the port to your needs
$port = 8080;
if( $strict // wpmu_create_blog uses strict mode
&& is_multisite() // multisite check
&& $port == parse_url( $raw_username, PHP_URL_PORT ) // raw domain has port
&& false === strpos( $username, ':' . $port ) // stripped domain is without correct port
)
$username = str_replace( $port, ':' . $port, $username ); // replace e.g. example.tld8080 to example.tld:8080
return $username;
}, 1, 3 );
/**

*/
add_action( 'load-network.php', function()
{
add_filter( 'option_active_plugins', function( $value )
{
add_filter( 'option_siteurl', function( $value )
{
// Edit the port to your needs

```

<p>I develop my custom widget with setting where I can set up custom color for the widget. I use this code to initialize <code>wpColorPicker</code> instead of default text input in <code>form()</code> method of Widget class:</p>
<pre><code>jQuery(document).ready(function($){
$('#<?php echo $this->get_field_id( 'bg_color_1' ); ?>').wpColorPicker();
});
</code></pre>
<p>All works great but if you are trying change the color in Theme Customizer after changing value nothing happens: the Save button still not active and site page not refreshing with the new color.</p>
<p>Previously trying for triggering <code>change</code> event, but not working:</p>
<pre><code>$('#<?php echo $this->get_field_id( 'bg_color_1' ); ?>').wpColorPicker({
change: function(event, ui) {
$('#<?php echo $this->get_field_id( 'bg_color_1' ); ?>').change();

<p>How to reload the page preview (trigger the event when value inside my input have been changed)?</p>

<p>On attachment page I would like to display all images belonging to the parent post, so there should a thumbnail gallery. Using... </p>
<pre><code>$parent = get_post_field( 'post_parent', get_the_ID() );
$gallery = get_post_gallery( $parent, false );
</code></pre>
<p>...gives this which is kinda weird to use. Why are ids seperatated from src?
How do I even get ID of that thumbnail to get the permalink? Even If I get this working by some complicated core, it feels dirty. Isn't there a better solution?</p>
<pre><code>array (size=3)
'columns' => string '4' (length=1)
'ids' => string '8844,8853,8498,8845,8846,8847,8848,8849,8852,8854,8843,8851,8855,8499,9672,9673' (length=79)
'src' =>
array (size=16)
0 => string 'http://localhost/biljke/wp-content/uploads/2015/05/uljana-repica-251-200x200.jpg' (length=80)
1 => string 'http://localhost/biljke/wp-content/uploads/2015/05/uljana-repica-33-200x200.jpg' (length=79)
2 => string 'http://localhost/biljke/wp-content/uploads/2015/05/uljana-repica-13-200x200.jpg' (length=79)
3 => string 'http://localhost/biljke/wp-content/uploads/2015/05/uljana-repica-26-200x200.jpg' (length=79)
</code></pre>
<p>I need something like this</p>
<pre><code><?php foreach($gallery as $img) : ?>
<a href="<?php echo get_permalink($img->ID); ?>">
<img src="<?php echo $img->src ?>" alt=" -<?php echo $img->title " />
</a>
<?php endforeach; ?>
</code></pre>
<p>There is also <code>get_post_gallery_images()</code> but it returns only thumbnail urls</p>

On attachment page I would like to display all images belonging to the parent post, so there should a thumbnail gallery. Using...
```
$parent = get_post_field( 'post_parent', get_the_ID() );
$gallery = get_post_gallery( $parent, false );
```
...gives this which is kinda weird to use. Why are ids seperatated from src?
How do I even get ID of that thumbnail to get the permalink? Even If I get this working by some complicated core, it feels dirty. Isn't there a better solution?
```
array (size=3)
'columns' => string '4' (length=1)
'ids' => string '8844,8853,8498,8845,8846,8847,8848,8849,8852,8854,8843,8851,8855,8499,9672,9673' (length=79)
'src' =>
array (size=16)
0 => string 'http://localhost/biljke/wp-content/uploads/2015/05/uljana-repica-251-200x200.jpg' (length=80)
1 => string 'http://localhost/biljke/wp-content/uploads/2015/05/uljana-repica-33-200x200.jpg' (length=79)
2 => string 'http://localhost/biljke/wp-content/uploads/2015/05/uljana-repica-13-200x200.jpg' (length=79)
3 => string 'http://localhost/biljke/wp-content/uploads/2015/05/uljana-repica-26-200x200.jpg' (length=79)
```
I need something like this
```
<?php foreach($gallery as $img) : ?>
<a href="<?php echo get_permalink($img->ID); ?>">
<img src="<?php echo $img->src ?>" alt=" -<?php echo $img->title " />
</a>
<?php endforeach; ?>
```
There is also `get_post_gallery_images()` but it returns only thumbnail urls

**Warning: This is just a test for dev installs and not production sites**
I was curious to see if there was a workaround, for those who want to develope multisites on their dev installs but on different ports than `:80` and `:443`, e.g. `:8080`.
I only found this [blog post](http://benohead.com/wordpress-running-multisite-different-port/) by Henri Benoit. There he gives examples how to modify the 3.9.1 core, to get around the core restrictions.
Here's a *must-use* plugin `/wp-content/mu-plugins/wpse-ms-on-different-port.php` where we try to avoid core modifications:
```
<?php
/**
* Test for multisite support on a different port than :80 and :443 (e.g. :8080)
*
* Here we assume that the 'siteurl' and 'home' options contain the :8080 port
*
* WARNING: Not suited for production sites!
*/
/**
* Get around the problem with wpmu_create_blog() where sanitize_user()
* strips out the semicolon (:) in the $domain string
* This means created sites with hostnames of
* e.g. example.tld8080 instead of example.tld:8080
*/
add_filter( 'sanitize_user', function( $username, $raw_username, $strict )
{
// Edit the port to your needs
$port = 8080;
if( $strict // wpmu_create_blog uses strict mode
&& is_multisite() // multisite check
&& $port == parse_url( $raw_username, PHP_URL_PORT ) // raw domain has port
&& false === strpos( $username, ':' . $port ) // stripped domain is without correct port
)
$username = str_replace( $port, ':' . $port, $username ); // replace e.g. example.tld8080 to example.tld:8080
return $username;
}, 1, 3 );
/**
* Temporarly change the port (e.g. :8080 ) to :80 to get around
* the core restriction in the network.php page.
*/
add_action( 'load-network.php', function()
{
add_filter( 'option_active_plugins', function( $value )
{
add_filter( 'option_siteurl', function( $value )
{
// Edit the port to your needs
$port = 8080;
// Network step 2
if( is_multisite() || network_domain_check() )
return $value;
// Network step 1
static $count = 0;
if( 0 === $count++ )
$value = str_replace( ':' . $port, ':80', $value );
return $value;
} );
return $value;
} );
} );
```
I just tested this on my dev install, but this might need more checks of course ;-)

<p>I am trying to use the WordPress Rest Api with authentication to get more data from the API. I have installed the Oauth plugin, rest-api plugin, and gotten API credentials from WP-CLI.</p>
<p>I have figured out how to access data without authorization. This works:</p>
<pre><code>// set our end point
$domain = "http://localhost/wp-api";
$endpoint = $domain."/wp-json/wp/v2/posts/";
$curl = curl_init($endpoint);
curl_setopt_array($curl, [
CURLOPT_RETURNTRANSFER => true,
CURLOPT_URL => $endpoint,
]);
$response = curl_exec($curl);
$decoderesponse = json_decode($response, true);
?>
<pre>
<?php print_r($decoderesponse); ?>
</pre>
</code></pre>
<p>But I can't figure out how to authenticate with credentials. Here is my attempt. I am not sure if "key" and "secret" are correct.</p>
<pre><code>// Oauth credentials from wp-cli
$ID = "4";
$Key = "l8XZD9lX89kb";
$Secret = "UUbcc8vjUkGjuDyvK1gRTts9sZp2N8k9tbIQaGjZ6SNOyR4d";
// set our end point
$domain = "http://localhost/wp-api";
$endpoint = $domain."/wp-json/wp/v2/posts/1/revisions";
$headers[] = "key=$Key";
$headers[] = "secret=$Secret";
$curl = curl_init($endpoint);
curl_setopt_array($curl, [
CURLOPT_HTTPHEADER => $headers,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_URL => $endpoint,
]);
$response = curl_exec($curl);
$decoderesponse = json_decode($response, true);
?>
<pre>
<?php print_r($decoderesponse); ?>
</pre>
</code></pre>
<p>The output is</p>
<pre><code>Array
(
[code] => rest_cannot_read
[message] => Sorry, you cannot view revisions of this post.
[data] => Array
(
[status] => 401
)
)
</code></pre>
<p>How can I get this to work? Thank you.</p>

"text": "<p>Let's go step by step here. Looks like you're trying to use OAuth just for authentication, <strong><em>but before you can do so you need to get the Access Token</em></strong> which will be used to authenticate when you make your API calls. </p>\n\n<p>Because this is using OAuth version 1, in order to obtain the <strong>Access Token</strong> you must do the following:</p>\n\n<ol>\n<li>First, setup an application, make a call to the site to obtain the <strong>Request Token</strong> (temp credentials) using the Client ID and Secret for the application</li>\n<li>Second, make a call to the site to Authorize the application with the <strong>Request Token</strong> from first step (user-facing, see below).</li>\n<li>Third, after authorization has been completed, you then make a call to the site to obtain the <strong>Access Token</strong> (now that application has been authorized)</li>\n</ol>\n\n<p>I recommend using Postman for the first few steps, because they only need to be completed once. Postman will also handle generating the <code>timestamp</code>, <code>nonce</code> and <code>oauth signature</code>, so if you're not using an OAuth library, then you should absolutely use Postman. Once you have your <strong>Access Token</strong> you can make the calls via CURL without any libraries.</p>\n\n<p><a href=\"https://www.getpostman.com/\" rel=\"noreferrer\">https://www.getpostman.com/</a></p>\n\n<h2>First Step (setup application)</h2>\n\n<p>Install WP OAuth 1 plugin, activate, then goto menu item under <strong><em>Users > Applications</em></strong>. Add new application, fill out name and description. For callback either the URL to redirect the user to (after authorizing), or <code>oop</code> for Out-of-Band flow which will redirect to an internal page which displays the verifier token (instead of redirecting).</p>\n\n<p><a href=\"https://github.com/WP-API/OAuth1/blob/master/docs/basics/Registering.md\" rel=\"noreferrer\">https://github.com/WP-API/OAuth1/blob/master/docs/basics/Registering.md</a></p>\n\n<p>To proceed to the second step a call needs to be made to your site, using the <strong>Client ID</strong> and <strong>Client Secret</strong> from the created application, to get temporary credentials (Request Token).</p>\n\n<p>Open up Postman, create a new call to <code>http://website.com/oauth1/request</code>, click on the Authorization tab, select OAuth 1.0 from dropdown, enter in the Client Key, Client Secret, set signature method to <code>HMAC-SHA1</code>, enable add params to header, <strong>encode oauth signature</strong>, then click <strong>Update Request</strong></p>\n\n<p><a href=\"https://i.stack.imgur.com/DjI4J.png\" rel=\"noreferrer\"><img src=\"https://i.stack.imgur.com/DjI4J.png\" alt=\"Postman OAuth1 Request\"></a></p>\n\n<p>Postman will auto generate the signature, nonce, and timestamp for you, and add them to the header (you can view under Headers tab).</p>\n\n<p>Click Send and you should get a response that includes <code>oauth_token</code> and <code>oauth_token_secret</code>:\n<a href=\"https://i.stack.imgur.com/Paf61.png\" rel=\"noreferrer\"><img src=\"https://i.stack.imgur.com/Paf61.png\" alt=\"Postman OAuth1 Request Response\"></a></p>\n\n<p>These values will be used in the next step to authorize the application under your WordPress user account.</p>\n\n<h2>Second Step (authorize application)</h2>\n\n<p>Authorization step only needs to be completed once, this step is user-facing, and the one that everyone is familiar with. This step is required because you're using OAuth1, and the application needs to be associated with a WordPress user account. Think of when a site allows you to login with Facebook ... they direct you to Facebook where you login and click \"Authorize\" ... this needs to be done, just through your WordPress site.</p>\n\n<p>I recommend using your Web Browser for this step, as you can easily just set the variables in URL, and this provides the \"Authorize\" page to authorize the application.</p>\n\n<p>Open your web browser and type in the URL to your site, like this:\n<code>http://website.com/oauth1/authorize</code></p>\n\n<p>Now add on to this URL, <code>oauth_consumer_key</code> (Client ID), <code>oauth_token</code> and <code>oauth_token_secret</code> (from previous step). In my example this is the full URL:</p>\n\n<pre><code>http://website.com/oauth1/authorize?oauth_consumer_key=TUPFNj1ZTd8u&oauth_token=J98cN81p01aqSdFd9rjkHZWI&oauth_token_secret=RkrMhw8YzXQljyh99BrNHmP7phryUvZgVObpmJtos3QExG1O\n</code></pre>\n\n<p><a href=\"https://i.stack.imgur.com/p752F.png\" rel=\"noreferrer\"><img src=\"https://i.stack.imgur.com/p752F.png\" alt=\"OAuth1 Authorize Application\"></a></p>\n\n<p>Once you click on Authorize, you will get another screen with the verification token. In my example this is the verification token returned <code>E0JnxjjYxc32fMr2AF0uWsZm</code></p>\n\n<h2>Third Step (get access token)</h2>\n\n<p>Now that we have authorized the application, we need to make one last call to get the Authorization Token which will be used to make all your API calls. Just like the first step i'm going to use Postman (because signature is required to be HMAC-SHA1), and it makes it 100x easier to complete these steps.</p>\n\n<p>Open up Postman again, and change the URL to <code>http://website.com/oauth1/access</code></p>\n\n<p>Make sure to add the Token, and Token Secret (values from the first step), then click on <strong>Params</strong> to show the boxes below the URL. On the left type in <strong>oauth_verifier</strong> and on the right, enter the code from the second step, the <strong>Verification Token</strong></p>\n\n<p><a href=\"https://i.stack.imgur.com/6WoIt.png\" rel=\"noreferrer\"><img src=\"https://i.stack.imgur.com/6WoIt.png\" alt=\"Postman OAuth1 Access Step\"></a></p>\n\n<p>Make sure to click Update Request, then click Send, and you should get a response back with <code>oauth_token</code> and <code>oauth_token_secret</code> ... this is what you need to make your API calls with! Discard the original ones from step 1, save these ones in your code or somewhere else safe.</p>\n\n<p><a href=\"https://i.stack.imgur.com/k1dRI.png\" rel=\"noreferrer\"><img src=\"https://i.stack.imgur.com/k1dRI.png\" alt=\"Postman OAuth1 Access Response\"></a></p>\n\n<p>You can then make an API call to your site, setting the headers with the returned token, and token secret.</p>\n\n<p>You can pass this multiple ways, via Authorization header, in GET parameters, or POST (if encoded as application/x-www-form-urlencoded). Keep in mind you MUST pass the signature, timestamp, and nonce. I didn't realize how long this reply would take me, so i'll update this tomorrow with example on doing that with your code.</p>\n\n<p>I strongly recommend installing Rest API log so you can view log of API calls, and see what was sent, returned, etc. This will help with debugging tremendously.</p>\n\n<p><a href=\"https://github.com/petenelson/wp-rest-api-log\" rel=\"noreferrer\">https://github.com/petenelson/wp-rest-api-log</a></p>\n"

I am trying to use the WordPress Rest Api with authentication to get more data from the API. I have installed the Oauth plugin, rest-api plugin, and gotten API credentials from WP-CLI.
I have figured out how to access data without authorization. This works:
```
// set our end point
$domain = "http://localhost/wp-api";
$endpoint = $domain."/wp-json/wp/v2/posts/";
$curl = curl_init($endpoint);
curl_setopt_array($curl, [
CURLOPT_RETURNTRANSFER => true,
CURLOPT_URL => $endpoint,
]);
$response = curl_exec($curl);
$decoderesponse = json_decode($response, true);
?>
<pre>
<?php print_r($decoderesponse); ?>
</pre>
```
But I can't figure out how to authenticate with credentials. Here is my attempt. I am not sure if "key" and "secret" are correct.
```
// Oauth credentials from wp-cli
$ID = "4";
$Key = "l8XZD9lX89kb";
$Secret = "UUbcc8vjUkGjuDyvK1gRTts9sZp2N8k9tbIQaGjZ6SNOyR4d";
// set our end point
$domain = "http://localhost/wp-api";
$endpoint = $domain."/wp-json/wp/v2/posts/1/revisions";
$headers[] = "key=$Key";
$headers[] = "secret=$Secret";
$curl = curl_init($endpoint);
curl_setopt_array($curl, [
CURLOPT_HTTPHEADER => $headers,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_URL => $endpoint,
]);
$response = curl_exec($curl);
$decoderesponse = json_decode($response, true);
?>
<pre>
<?php print_r($decoderesponse); ?>
</pre>
```
The output is
```
Array
(
[code] => rest_cannot_read
[message] => Sorry, you cannot view revisions of this post.
[data] => Array
(
[status] => 401
)
)
```
How can I get this to work? Thank you.

Let's go step by step here. Looks like you're trying to use OAuth just for authentication, ***but before you can do so you need to get the Access Token*** which will be used to authenticate when you make your API calls.
Because this is using OAuth version 1, in order to obtain the **Access Token** you must do the following:
1. First, setup an application, make a call to the site to obtain the **Request Token** (temp credentials) using the Client ID and Secret for the application
2. Second, make a call to the site to Authorize the application with the **Request Token** from first step (user-facing, see below).
3. Third, after authorization has been completed, you then make a call to the site to obtain the **Access Token** (now that application has been authorized)
I recommend using Postman for the first few steps, because they only need to be completed once. Postman will also handle generating the `timestamp`, `nonce` and `oauth signature`, so if you're not using an OAuth library, then you should absolutely use Postman. Once you have your **Access Token** you can make the calls via CURL without any libraries.
<https://www.getpostman.com/>
First Step (setup application)
------------------------------
Install WP OAuth 1 plugin, activate, then goto menu item under ***Users > Applications***. Add new application, fill out name and description. For callback either the URL to redirect the user to (after authorizing), or `oop` for Out-of-Band flow which will redirect to an internal page which displays the verifier token (instead of redirecting).
<https://github.com/WP-API/OAuth1/blob/master/docs/basics/Registering.md>
To proceed to the second step a call needs to be made to your site, using the **Client ID** and **Client Secret** from the created application, to get temporary credentials (Request Token).
Open up Postman, create a new call to `http://website.com/oauth1/request`, click on the Authorization tab, select OAuth 1.0 from dropdown, enter in the Client Key, Client Secret, set signature method to `HMAC-SHA1`, enable add params to header, **encode oauth signature**, then click **Update Request**
[](https://i.stack.imgur.com/DjI4J.png)
Postman will auto generate the signature, nonce, and timestamp for you, and add them to the header (you can view under Headers tab).
Click Send and you should get a response that includes `oauth_token` and `oauth_token_secret`:
[](https://i.stack.imgur.com/Paf61.png)
These values will be used in the next step to authorize the application under your WordPress user account.
Second Step (authorize application)
-----------------------------------
Authorization step only needs to be completed once, this step is user-facing, and the one that everyone is familiar with. This step is required because you're using OAuth1, and the application needs to be associated with a WordPress user account. Think of when a site allows you to login with Facebook ... they direct you to Facebook where you login and click "Authorize" ... this needs to be done, just through your WordPress site.
I recommend using your Web Browser for this step, as you can easily just set the variables in URL, and this provides the "Authorize" page to authorize the application.
Open your web browser and type in the URL to your site, like this:
`http://website.com/oauth1/authorize`
Now add on to this URL, `oauth_consumer_key` (Client ID), `oauth_token` and `oauth_token_secret` (from previous step). In my example this is the full URL:
```
http://website.com/oauth1/authorize?oauth_consumer_key=TUPFNj1ZTd8u&oauth_token=J98cN81p01aqSdFd9rjkHZWI&oauth_token_secret=RkrMhw8YzXQljyh99BrNHmP7phryUvZgVObpmJtos3QExG1O
```
[](https://i.stack.imgur.com/p752F.png)
Once you click on Authorize, you will get another screen with the verification token. In my example this is the verification token returned `E0JnxjjYxc32fMr2AF0uWsZm`
Third Step (get access token)
-----------------------------
Now that we have authorized the application, we need to make one last call to get the Authorization Token which will be used to make all your API calls. Just like the first step i'm going to use Postman (because signature is required to be HMAC-SHA1), and it makes it 100x easier to complete these steps.
Open up Postman again, and change the URL to `http://website.com/oauth1/access`
Make sure to add the Token, and Token Secret (values from the first step), then click on **Params** to show the boxes below the URL. On the left type in **oauth\_verifier** and on the right, enter the code from the second step, the **Verification Token**
[](https://i.stack.imgur.com/6WoIt.png)
Make sure to click Update Request, then click Send, and you should get a response back with `oauth_token` and `oauth_token_secret` ... this is what you need to make your API calls with! Discard the original ones from step 1, save these ones in your code or somewhere else safe.
[](https://i.stack.imgur.com/k1dRI.png)
You can then make an API call to your site, setting the headers with the returned token, and token secret.
You can pass this multiple ways, via Authorization header, in GET parameters, or POST (if encoded as application/x-www-form-urlencoded). Keep in mind you MUST pass the signature, timestamp, and nonce. I didn't realize how long this reply would take me, so i'll update this tomorrow with example on doing that with your code.
I strongly recommend installing Rest API log so you can view log of API calls, and see what was sent, returned, etc. This will help with debugging tremendously.

<p>I want to serve a specific Wordpress page for multiple urls. Basically I want to point all the urls in a specific format to a known page:</p>
<pre><code>/some-prefix-* => /target-page
</code></pre>
<p>And accessing <code>/some-prefix-and-here-something</code> it should load <code>/target-page</code>.</p>
<p>How to do this?</p>
<p>Note I do <em>not</em> want to redirect the user but to be able to serve an existing page to multiple urls.</p>
<p>The <code>.htaccess</code> looks like this:</p>
<pre><code># BEGIN s2Member GZIP exclusions
RewriteEngine On RewriteRule ^prefix-*$ some/path/to/directory-$1 [NC,L]
<IfModule rewrite_module>
RewriteEngine On
RewriteBase /
RewriteCond %{QUERY_STRING} (^|\?|&)s2member_file_download\=.+ [OR]
RewriteCond %{QUERY_STRING} (^|\?|&)no-gzip\=1
RewriteRule .* - [E=no-gzip:1]
</IfModule>
# END s2Member GZIP exclusions
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
DirectoryIndex index.php index.html
</code></pre>
<p>I thought by adding <code>RewriteEngine On RewriteRule ^prefix-*$ some/path/to/directory-$1 [NC,L]</code> will serve <code>/prefix-*</code> from <code>some/path/to/directory-$1</code>. For example: when accessing <code>example.com/prefix-foo</code> should be the same with <code>example.com/some/path/to/directory-foo</code> (which resolves to <code>example.com/some/path/to/directory-foo/index.html</code>).</p>
<p>Also, if there is already a Wordpress page with the name <code>prefix-bar</code>, <code>/prefix-bar</code> should <em>not</em> load <code>example.com/some/path/to/directory-bar/index.html</code>.</p>

I want to serve a specific Wordpress page for multiple urls. Basically I want to point all the urls in a specific format to a known page:
```
/some-prefix-* => /target-page
```
And accessing `/some-prefix-and-here-something` it should load `/target-page`.
How to do this?
Note I do *not* want to redirect the user but to be able to serve an existing page to multiple urls.
The `.htaccess` looks like this:
```
# BEGIN s2Member GZIP exclusions
RewriteEngine On RewriteRule ^prefix-*$ some/path/to/directory-$1 [NC,L]
<IfModule rewrite_module>
RewriteEngine On
RewriteBase /
RewriteCond %{QUERY_STRING} (^|\?|&)s2member_file_download\=.+ [OR]
RewriteCond %{QUERY_STRING} (^|\?|&)no-gzip\=1
RewriteRule .* - [E=no-gzip:1]
</IfModule>
# END s2Member GZIP exclusions
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
DirectoryIndex index.php index.html
```
I thought by adding `RewriteEngine On RewriteRule ^prefix-*$ some/path/to/directory-$1 [NC,L]` will serve `/prefix-*` from `some/path/to/directory-$1`. For example: when accessing `example.com/prefix-foo` should be the same with `example.com/some/path/to/directory-foo` (which resolves to `example.com/some/path/to/directory-foo/index.html`).
Also, if there is already a Wordpress page with the name `prefix-bar`, `/prefix-bar` should *not* load `example.com/some/path/to/directory-bar/index.html`.

You can use [`template_include`](https://codex.wordpress.org/Plugin_API/Filter_Reference/template_include), but before you hook to this filter you must do the following steps:
1. Create page template. e.g: `page-target.php`
```
<?php
/**
* Template Name: Page Target
*/
...
```
2. Manually query the contents of `target-page` on `page-target.php` template, because the global `$post` will be referencing to your `some-prefix-*` page.
3. (Optional): Edit and apply page template `Page Target` to your `/target-page` from the Page Attributes
Then add the following to your `functions.php` file
```
add_filter('template_include', function($template) {
global $post;
$prefix = 'some-prefix-'; // Your prefix
$prefixExist = strpos($post->post_name, $prefix) !== false;
if ($prefixExist) {
return locate_template('page-target.php'); //Your template
}
return $template;
});
```
Above filter will override the template with `page-target.php` if condition met, otherwise default
### Edit:
I think I have found a better way to resolve this using [`add_rewrite_rule`](https://codex.wordpress.org/Rewrite_API/add_rewrite_rule)
```
function custom_rewrite_basic() {
$page_id = 123; //Your serve page id
add_rewrite_rule('^some-prefix-.*', 'index.php?page_id=' . $page_id, 'top');
}
add_action('init', 'custom_rewrite_basic');
```

How to determine if the current file is loaded in a plugin or in a theme? A boolean PHP function.
|
**1. The function:**
```
function wp543_is_plugin(){
return strpos( str_replace("\\", "/", plugin_dir_path( $file ) ) , str_replace("\\", "/", WP_PLUGIN_DIR) ) !== false;
}
```
**2. Call the function:**
```
wp543_is_plugin();
```
Calling this function will return `true` if the current file is loaded in a plugin and `false` if it is loaded in a theme.
**Edit:** Since this answer has received many downvotes I've found the solution that should fix my previous mistake. *And I intentionally solved it with just one line of code.* :)
How this function works now:
1. Replaces all backslashes wit forward slashes.
2. `plugin_dir_path( __FILE__ )` will always return the full path to current file. No matter if thatfile is within a plugin or theme.
3. `WP_PLUGIN_DIR` will always return the plugins path, so we just check if that path is found in `plugin_dir_path( __FILE__ )`
4. If it is found than the current file is within a plugin and return `true` otherwise `false`.

<p>I just started to work with Wordpress (Theme Development) and due to awesome functions like bloginfo('description') and others my static homepage looks a lot like a regular site, but editable with the Wordpress Dashboard.</p>
<p>But now, I want to put more information on my homepage which I can edit through the dashboard. I guess this is really basic Wordpress and that a simple Wordpress function or MySQL-query should be enough, but I can't seem to find it. </p>
<p>This is my code right now: </p>
<pre><code> <div class="fp-container">
<div class="fp-border">
<h1 class="fp-description"><?php bloginfo('description'); ?></h1>
</div>
<div class="fp-text">
<p><?php bloginfo('description'); ?></p>
</div>
</code></pre>
<p>As you can see, between the '< p>' and '< /p>' I call the description for the second time, how can I call another string that can be entered through the Dashboard?</p>
<p>I've asked this question on stackoverflow.com, and the only answer I got was that I should use the_content(), but that only works once, and I will need multiple text boxes on my frontpage. How can I do this?</p>

I just started to work with Wordpress (Theme Development) and due to awesome functions like bloginfo('description') and others my static homepage looks a lot like a regular site, but editable with the Wordpress Dashboard.
But now, I want to put more information on my homepage which I can edit through the dashboard. I guess this is really basic Wordpress and that a simple Wordpress function or MySQL-query should be enough, but I can't seem to find it.
This is my code right now:
```
<div class="fp-container">
<div class="fp-border">
<h1 class="fp-description"><?php bloginfo('description'); ?></h1>
</div>
<div class="fp-text">
<p><?php bloginfo('description'); ?></p>
</div>
```
As you can see, between the '< p>' and '< /p>' I call the description for the second time, how can I call another string that can be entered through the Dashboard?
I've asked this question on stackoverflow.com, and the only answer I got was that I should use the\_content(), but that only works once, and I will need multiple text boxes on my frontpage. How can I do this?

**1. The function:**
```
function wp543_is_plugin(){
return strpos( str_replace("\\", "/", plugin_dir_path( $file ) ) , str_replace("\\", "/", WP_PLUGIN_DIR) ) !== false;
}
```
**2. Call the function:**
```
wp543_is_plugin();
```
Calling this function will return `true` if the current file is loaded in a plugin and `false` if it is loaded in a theme.
**Edit:** Since this answer has received many downvotes I've found the solution that should fix my previous mistake. *And I intentionally solved it with just one line of code.* :)
How this function works now:
1. Replaces all backslashes wit forward slashes.
2. `plugin_dir_path( __FILE__ )` will always return the full path to current file. No matter if thatfile is within a plugin or theme.
3. `WP_PLUGIN_DIR` will always return the plugins path, so we just check if that path is found in `plugin_dir_path( __FILE__ )`
4. If it is found than the current file is within a plugin and return `true` otherwise `false`.

You may need to regenerate your images. There are plugins to accomplish this or re-upload your image and see if the size doesn't take affect. It won't happen automatically to existing files.
First, check your uploads directory to see if the files exists that way you know they are being generated. Then try another function to output the results.
What do you end up with when you use:
```
$attachment_id = get_post_thumbnail_id( $post->ID );
$img_src = wp_get_attachment_image_url( $attachment_id, 'cover-size' );
$img_srcset = wp_get_attachment_image_srcset( $attachment_id, 'cover-size' );
```
Also if may be handy to output your meta data for that attachment - specifically to see the `size` information:
```
print_r ( wp_get_attachment_metadata( $attachment_id) );
```
The above `wp_get_attachment_image_srcset` requires WordPress 4.4 and you can find more information about [Responsive Images in WordPress 4.4](https://make.wordpress.org/core/2015/11/10/responsive-images-in-wordpress-4-4/).
Assuming the files exist:
* [the\_post\_thumbnail](https://codex.wordpress.org/Function_Reference/the_post_thumbnail) `( $size, $attr )`
* [get\_the\_post\_thumbnail](https://developer.wordpress.org/reference/functions/get_the_post_thumbnail/) `( int|WP_Post $post = null, string|array $size = 'post-thumbnail', string|array $attr = '' )`
Are you in a Loop or outside of it?
If you're inside try `the_post_thumbnail ('cover-size');`
otherwise `echo get_the_post_thumbnail ($post,'cover-size');`

<p>I have a filter for the Gallery Shortcode where I grab IDs for images used in a post and using the IDs I grab their meta data. Now I need a way to use the <code>$copyright</code> variable in a filter for grabbing <code>post_content</code> so I can echo the content of that variable.</p>
<p>Is there a way to reuse a variable in different filter or maybe there is a better way for what I am trying to accomplish?</p>
<pre><code>function wpse_get_full_size_gallery_images( $gallery, $post, $galleries ) {
$ids = explode( ',', $galleries['include'] );
$copyright = array();
foreach( $ids as $id )
$copyright[] = get_post_meta( $id, 'wiki_copyright', true );
return $gallery;
}
add_filter( 'shortcode_atts_gallery', 'wpse_get_full_size_gallery_images', 10, 3 );
function my_the_content_filter( $content ) {
//pass here the copyright array and append it at the end
$content .= $copyright;
return $content;
}
add_filter( 'the_content', 'my_the_content_filter', 20 );

Globalizing a variable is certainly not one of them and you should avoid doing that. Globalizing is an easy way out to solve any issue, but believe me you'll spend days debugging an issue which does not give you any debugging errors when something breaks your global. </p>\n\n<p>WordPress alreay made a huge mess with globals. Just go through questions and answers on this site and check how many are using the globals <code>$wp_query</code>, <code>$posts</code> and <code>$post</code> as local variables.</p>\n\n<p>I personally use <code>$copyright</code> as a variable to hold date info. If we globalize <code>$copyright</code> with a string of id's as in your case, either my variable is going to break the global or the global is going to break my variable. Worst is, I would not get any debug errors and I would not know where my values are changed. So never ever globalize variables, IMHO, it is really bad practice as there are many other options</p>\n\n<p>A quick option that comes to mind is storing your data with the Options API. It is easy and does not require huge overheads as options are cached, and they are save to use.</p>\n\n<p>Lets try the following: (<strong><em>NOTE:</strong> All code is untested so make sure to test this on local install first.

I have a filter for the Gallery Shortcode where I grab IDs for images used in a post and using the IDs I grab their meta data. Now I need a way to use the `$copyright` variable in a filter for grabbing `post_content` so I can echo the content of that variable.
Is there a way to reuse a variable in different filter or maybe there is a better way for what I am trying to accomplish?
```
function wpse_get_full_size_gallery_images( $gallery, $post, $galleries ) {
$ids = explode( ',', $galleries['include'] );
$copyright = array();
foreach( $ids as $id )
$copyright[] = get_post_meta( $id, 'wiki_copyright', true );
return $gallery;
}
add_filter( 'shortcode_atts_gallery', 'wpse_get_full_size_gallery_images', 10, 3 );
function my_the_content_filter( $content ) {
//pass here the copyright array and append it at the end
$content .= $copyright;
return $content;
}
add_filter( 'the_content', 'my_the_content_filter', 20 );
```
|
This is probably a good case for a global variable. Just make sure it is set to an array before you add to it and also when to attempt to output the content. Convert the array to a string before adding to content.
Also, make sure the meta data exists before adding to the array -- that way you're not adding empty copyright values.
**GLOBAL VERSION**
```
function wpse_get_full_size_gallery_images($gallery, $post, $galleries) {
// reference the global variable
global $copyright;
// make sure it's set
if( ! isset($copyright)) $copyright = array();
// grab the IDS
$ids = explode(',', $galleries[ 'include' ]);
foreach($ids as $id) {
// get the possible meta
$meta = get_post_meta($id, 'wiki_copyright', true);
// add them to the copyright array
// make sure to only add if it exists
if( !empty($meta)) $copyright[] = $meta;
}
return $gallery;
}
add_filter('shortcode_atts_gallery', 'wpse_get_full_size_gallery_images', 10, 3);
function my_the_content_filter($content) {
// reference the global variable
global $copyright;
// add copyright array converted to string if we have content
if( ! empty($copyright)) $content .= implode(',', $copyright);
return $content;
}
add_filter('the_content', 'my_the_content_filter', 20);
```
**STATIC VERSION**
If you don't like to use globals, *for whatever reason*, then consider a [static](http://php.net/manual/en/language.variables.scope.php#language.variables.scope.static) as an alternate [variable scope](http://php.net/manual/en/language.variables.scope.php) in PHP.
>
> Another important feature of variable scoping is the static variable. A static variable exists only in a local function scope, but it does not lose its value when program execution leaves this scope.
>
>
>
Since the persistent variable is tied to a single function scope we'll need to create the function outside any loops then reuse it for adding values in addition to retrieving those values.
*If you pass a new value; **add it**. If you don't pass a value; **get all values**.*
```
if( ! function_exists('copyrights')) {
function copyrights($value = '') {
// only this function has access to $_copyrights
static $_copyrights;
// expressions can't be assigned as defaults
// but we still want to initialize the value
if( ! isset($_copyrights)) {
$_copyrights = array();
}
// if we're passing new values then add them
if( ! empty($value)) {
$_copyrights[] = $value;
return true; // success
}
else {
// otherwise return uniques
$unique_list = array_unique($_copyrights);
// convert to string before they leave
return implode(", ", $unique_list);
}
}
}
add_filter('shortcode_atts_gallery', function($gallery, $post, $galleries) {
$ids = explode(',', $galleries[ 'include' ]);
foreach($ids as $id)
if( ! empty($meta = get_post_meta($id, 'wiki_copyright', true)))
copyrights($meta);
return $gallery;
}, 10, 3);
add_filter('the_content', function($content) {
return $content . copyrights();
}, 20);
```
TESTING
```
copyrights ( 123 );
copyrights ( 223 );
copyrights ( 333 );
copyrights ( 123 );
copyrights ( 111 );
copyrights ( 111 );
copyrights ( 111 );
echo ( copyrights() ); // 123, 223, 333, 111
```
**SINGLETON VERSION**
I actually never use globals because a [Singleton Pattern](http://www.phptherightway.com/pages/Design-Patterns.html#singleton) is my preferred method.
The idea is that you put all your methods on an instance of a class but only access it through a static method. By doing so, the class ensures there is only ever one single instance created.
```
if( ! class_exists('Copyrights')) {
class Copyrights {
private $copyrights;
private static $instance;
// PRIVATE CONSTRUCTOR
private function __construct() {
// initialize the array
$this->copyrights = array();
}
// STATIC SINGLETON
public static function getInstance() {
if(is_null(self::$instance)) {
self::$instance = new self();
}
return self::$instance;
}
// PUBLIC METHODS
public function toString() {
$unique_list = array_unique($this->copyrights);
return implode(", ", $unique_list);
}
public function add($value = '') {
if( ! empty($value)) {
$this->copyrights[] = $value;
}
}
}
}
add_filter('shortcode_atts_gallery', function($gallery, $post, $galleries) {
$ids = explode(',', $galleries[ 'include' ]);
foreach($ids as $id)
if( ! empty($meta = get_post_meta($id, 'wiki_copyright', true)))
Copyrights::getInstance()->add($meta);
return $gallery;
}, 10, 3);
add_filter('the_content', function($content) {
return $content . Copyrights::getInstance()->toString();
}, 20);
```
TESTING
```
Copyrights::getInstance()->add ( 123 );
Copyrights::getInstance()->add ( 223 );
Copyrights::getInstance()->add ( 333 );
Copyrights::getInstance()->add ( 123 );
Copyrights::getInstance()->add ( 111 );
Copyrights::getInstance()->add ( 111 );
Copyrights::getInstance()->add ( 111 );
echo Copyrights::getInstance()->toString(); // 123, 223, 333, 111
```
**SINGLETON PER POST VERSION**
Maybe the *single* most important aspect that has been overlooked in the debate of `global` vs. `the sky is falling` is the solution above (*and alternates proposed*) only cater to a single post. If you wanted to add your copyrights in a loop you would be screwed because all posts would be added to a single array.
With the singleton class, adding a per ID singleton is cake and arguably the best possible *option*.
```
if( ! class_exists('Copyrights')) {
class Copyrights {
private static $instance;
private $copyrights;
public $post_id;
// PRIVATE CONSTRUCTOR
private function __construct($post_id) {
// save the id
$this->post_id = $post_id;
// initialize the array
$this->copyrights = array();
}
// SINGLETON
public static function getInstance($post_id = 'NO ID') {
if(is_null(self::$instance)) self::$instance = array();
if(is_null(self::$instance[ $post_id ])) {
self::$instance[ $post_id ] = new self($post_id);
}
return self::$instance[ $post_id ];
}
// PUBLIC METHODS
public function toString() {
$unique_list = array_unique($this->copyrights);
return implode(", ", $unique_list);
}
public function add($value = '') {
if( ! empty($value)) {
$this->copyrights[] = $value;
}
}
}
}
add_filter('shortcode_atts_gallery', function($gallery, $post, $galleries) {
$ids = explode(',', $galleries[ 'include' ]);
foreach($ids as $id)
if( ! empty($meta = get_post_meta($id, 'wiki_copyright', true)))
Copyrights::getInstance($post->ID)->add($meta);
return $gallery;
}, 10, 3);
add_filter('the_content', function($content) {
global $post;
return $content . Copyrights::getInstance($post->ID)->toString();
}, 20);
```
TESTING
As you can see, having the the *option* to use `ID` as a key keeps things flexible.
```
Copyrights::getInstance( 1 )->add ( 123 );
Copyrights::getInstance( 1 )->add ( 223 );
Copyrights::getInstance( 2 )->add ( 333 );
Copyrights::getInstance( 2 )->add ( 123 );
Copyrights::getInstance( 2 )->add ( 111 );
Copyrights::getInstance( 2 )->add ( 111 );
Copyrights::getInstance( 2 )->add ( 111 );
Copyrights::getInstance()->add ( 111 );
Copyrights::getInstance()->add ( 444 );
Copyrights::getInstance()->add ( 555 );
Copyrights::getInstance()->add ( 888 );
echo Copyrights::getInstance( 1 )->toString(); // 123, 223
echo Copyrights::getInstance( 2 )->toString(); // 333, 123, 111
echo Copyrights::getInstance()->toString(); // 111, 444, 555, 888
```
At the point that someone thinks it's a good idea to store a temporary value in the [database](https://codex.wordpress.org/Options_API) because they don't understand PHP then it's a good time to rethink the problem.
---
**UPDATE**
I [solved](https://wordpress.stackexchange.com/a/213223/84219) the question using a [global](http://php.net/manual/en/language.variables.scope.php) variable but rethinking the issue you can do away with a lot of complexities by justing using [the content](https://codex.wordpress.org/Function_Reference/the_content) filter hook alone -- which keeps the issue localized.
In this case, when `the_content` runs, we check for [all galleries](https://codex.wordpress.org/Function_Reference/get_post_galleries) and output only the [relevant data](http://php.net/manual/en/function.array-filter.php).

add_filter('the_content', 'add_copyright_to_content');
function add_copyright_to_content($content) {
// pull all galleries from the post
$galleries = get_post_galleries(get_post(), false);
// no gallery? then let's get out of here
if(empty($galleries)) return $content;
$all = '';
// gather all ids
foreach($galleries as $gallery) $all .= $gallery[ 'ids' ] . ',';
// convert them to an array with unique ids
$all = array_unique(array_filter(explode(',', $all)));
// replace id for copyright info on the image meta
foreach($all as $key => $id) $all [ $key ] = get_post_meta($id, 'wiki_copyright', true);
// return non-empty values to the end of the content
return $content . implode(', ', array_filter($all));
}

This function uses `get_the_posts_pagination()` which uses the GLOBAL `$wp_query` to setup the `paginate_links()` function, so I believe that doesn't work for `get_posts`.
Try use the function `paginate_links()` by itself or the function `posts_nav_link()`

<p>I want to be able to login to wordpress through a customized function, no dashboard etc showing. I just want the user being logged in and then I want to handle stuff like customized forms, update stuff into db etc for a specific logged in user.</p>
<p>I thought <code>wp_signon</code>() looked like a good alternative, but it opens up the dashboard menu that I really didn't want it to. Is there a possible way not show dashboard-menu when logged in (basically show nothing, just being logged in with a cookie) as a client? When I log in as adminstrator (through /wp-admin) I want the "normal" functionality with dashboard etc.</p>
<p>Is this possible?</p>

I assume you're referring to the black bar that may run across the top of a web page. That's called the 'Toolbar'. However, an earlier version of it was called the 'Admin Bar', and that name is still used in the code.
To never display it, add this to `functions.php`
```
function my_function_admin_bar(){
return false;
}
add_filter( 'show_admin_bar' , 'my_function_admin_bar');
```
or to just show the bar for admins
```
function my_function_admin_bar($content) {
return ( current_user_can( 'administrator' ) ) ? $content : false;
}
add_filter( 'show_admin_bar' , 'my_function_admin_bar');
```
(Or similarly in a plugin.)
See [the Codex](https://codex.wordpress.org/Plugin_API/Filter_Reference/show_admin_bar).
(Also, you should be able to use `wp_signon()` if you wish.)

'SELECT * FROM language_skills'
);
foreach ($languages as $language){
//do some echo of html
}
?>
```
How can I achieve a result here? I now, echo waits for a string there. I thought about heredoc and a custom function, but I can't seem to achieve the result.
**UPDATE:**
I managed to get my data. It's in an array. How I can show all the array results in above situation?
My array goes something like this:
```
<option value="$value">$content</option>
```
It shows exactly what I want when I use:
```
[shortcode].$array[index].[/shortcode]
```
How can I add all the indexes? I tried for each but it doesn't work in between shortcodes
ANSWER:
I used implode to change array to a string and code now works as i want.

I assume you're referring to the black bar that may run across the top of a web page. That's called the 'Toolbar'. However, an earlier version of it was called the 'Admin Bar', and that name is still used in the code.
To never display it, add this to `functions.php`
```
function my_function_admin_bar(){
return false;
}
add_filter( 'show_admin_bar' , 'my_function_admin_bar');
```
or to just show the bar for admins
```
function my_function_admin_bar($content) {
return ( current_user_can( 'administrator' ) ) ? $content : false;
}
add_filter( 'show_admin_bar' , 'my_function_admin_bar');
```
(Or similarly in a plugin.)
See [the Codex](https://codex.wordpress.org/Plugin_API/Filter_Reference/show_admin_bar).
(Also, you should be able to use `wp_signon()` if you wish.)

Is your class `wpe_Main` file is the mail file of the plugin?
Because `__FILE__` should return main plugin file path. So if your `wpe_Main` class is in a sub directory then the register activation won't work.
If you want you can try like below to avoid `__FILE__` confusion
Plugin path: `wp-content/plugin/sampleplugin/sample.php`
Then the hook should be like below
```
register_activation_hook( 'sampleplugin/sample.php',
array($this,'create_wpe_enquiry_table'));
```
**Updated** after comments
If Your class in main plugin file then **for sure** the function is executing on plugin activation. Your table are not creating might be SQL error or typos. So please check the function responsible for creating table.
For simple testing on activation function try the below code
```
update_option('activation_test','its working');
```
then check the options, you can see that it should been updated or you can even send mail to test.
Testing the activation function is your conviniens. At the end `register_activation_hook` **will work on OOPS without any problem**. Check [Reference](https://codex.wordpress.org/Function_Reference/register_activation_hook#Examples)

<p>I have a Wordpress menu that I am using as a Hamburger menu for smaller mobile devices. Since there really isn't a "hover" event for touch devices, I have changed the main menu items to show their corresponding sub menus on "click" (or "touch"). The problem is that I can't make the main menu items clickable. Also, I don't see an option in "wp_nav_menu" to show the top level item on the submenu. That is how I would be inclined to use it. I need a workaround or something like that.</p>

You could solve this with other nasty hacks but here's *kind of* WordPress way:
**In your `header.php`**
```
<?php
// User is not using mobile
if( ! wp_is_mobile() ) {
wp_nav_menu(); // Your "original menu"
}
// User is using mobile
else if( wp_is_mobile() ) {
wp_nav_menu(); // Your another menu that only has top level items
}
?>
```
Keep in mind that `wp_is_mobile()` also considers tablets as mobile devices and you should always carefully think this through because if PC window is resized to small / narrow -> it obviously doesn't count it as mobile.
**And jQuery to disable your click event:**
```
var isMobile = false;
// Check if user is using mobile device
if (/Android|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera Mini/i.test(navigator.userAgent)) {
isMobile = true;
}
if( ! isMobile ) {
// Your usual click event
}
```

I have tried below script to load jQuery UI Autocomplete in theme. But it doesn't load their related scripts. How should I call it to work.
```
wp_enqueue_script('jquery-ui-autocomplete');
```
I think below scripts are jQuery UI related scripts for autocomplete but it's doesn't load.
```
<script type='text/javascript' src='http://localhost/wordpress/wp-includes/js/jquery/ui/jquery.ui.core.min.js?ver=1.10.2'></script>
<script type='text/javascript' src='http://localhost/wordpress/wp-includes/js/jquery/ui/jquery.ui.widget.min.js?ver=1.10.2'></script>
<script type='text/javascript' src='http://localhost/wordpress/wp-includes/js/jquery/ui/jquery.ui.position.min.js?ver=1.10.2'></script>
<script type='text/javascript' src='http://localhost/wordpress/wp-includes/js/jquery/ui/jquery.ui.menu.min.js?ver=1.10.2'></script>
<script type='text/javascript' src='http://localhost/wordpress/wp-includes/js/jquery/ui/jquery.ui.autocomplete.min.js?ver=1.10.2'></script>
```

You could solve this with other nasty hacks but here's *kind of* WordPress way:
**In your `header.php`**
```
<?php
// User is not using mobile
if( ! wp_is_mobile() ) {
wp_nav_menu(); // Your "original menu"
}
// User is using mobile
else if( wp_is_mobile() ) {
wp_nav_menu(); // Your another menu that only has top level items
}
?>
```
Keep in mind that `wp_is_mobile()` also considers tablets as mobile devices and you should always carefully think this through because if PC window is resized to small / narrow -> it obviously doesn't count it as mobile.
**And jQuery to disable your click event:**
```
var isMobile = false;
// Check if user is using mobile device
if (/Android|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera Mini/i.test(navigator.userAgent)) {
isMobile = true;
}
if( ! isMobile ) {
// Your usual click event
}
```

I'm trying to update the Advanced Custom Fields meta value associated with a custom taxonomy term
```
$term_status = wp_update_term( $rate_id, 'rate', $term_data );
$term_id = $term_status['term_taxonomy_id'];
update_field( 'field_56829855eebc9',$rate_daily,$term_id );
```
However, I'm not getting the field updated. I have tried the field name instead of the field key too.
|
I figured it out somehow..
Syntax of `update_field()`:
`update_field($field_key, $value, $post_id)`
MY MISTAKE:
I was using the wrong parameter for the `$post_id` which i thought was the Term Id of the custom taxonomy term.
CORRECT USAGE: rather than using term id (`$term_id` in my question), one should use a string with the taxonomy preppended to the $term\_id
ie `$post_id` = `$taxonomy.'_'.$term_id`
for eg: if your custom taxonomy is `foo` and the term id is `123`
then : `$post_id = foo_123`
Hope this is helpful for someone.
This is the first time I'm asking/answering a question here.

<p>I use the conditonal function <strong>is_singular($my_post_type)</strong> inside my plugin and it is very convenient.
The problem is that is doesn't work backend.</p>
<p>Is there an alternative that works frontend & backend ?
Thanks !</p>

Now I write an article attached a photo which is taken today and publish it today. I found that the URL of the photo was displayed as:

</a>
```
Why not `src="http://hwy.local/wp/wp-content/uploads/2016/01/scan-169x300.png"`?
1. The photo was taken today.
2. I upload it today.
3. The date on my OS is 2016-01-01.
Why is `uploads/2015/02/scan-169x300.png` in `src` not `uploads/2016/01/scan-169x300.png` in the `src`?

What date was/is the post published? Media uploads are added to the folder when the post/page was published, not the upload date. Was the post originally published in Feb 2015?

For example, this works:
```
'default' => '#ffffff'
```
But this does not:
```
$white = '#ffffff';
'default' => $white
```
How can I pass variables to key/value pairs?
Here is a more complete example for some context:
```
$white = '#ffffff';
$transport = 'refresh';
$wp_customize->add_setting('mytheme_text_color', array(
'default' => $white,
'transport' => $transport
));
```
In reply to jgraup:
This code works:
```
$wp_customize->add_setting('themeone_primary_nav_background_color', array(
'default' => '#181818',
'transport' => 'refresh'
));
```
This code doesn't:
```
$args = array('default' => '#181818', 'transport' => 'refresh');
$wp_customize->add_setting('themeone_primary_nav_background_color', $args);
```
When I customize my page colors in the admin section, I should see a "default" color button. In the former code, I see this button. In the latter code, I do not.

<p>There may be several aspects to my question but I feel in essence it's easy: how do you make sure changes to a child theme <code>style.css</code> are properly propagated across caches?</p>
<p>I read in a few places that WP should/would be placing the WP version in <code>nnn</code> when the resource is fetched as <code>http://host/wp-content/themes/theme-child/style.css?ver=nnn</code>. In my installation at <a href="http://frightanic.com/" rel="noreferrer">http://frightanic.com/</a> I see that the <em>parent theme</em> version is used instead.
I have W3 Total Cache and a CDN in place but even if they're disabled a resource like <code>wp-content/themes/frightanic/style.css?ver=3.0.7</code> is requested. <code>3.0.7</code> is the version of the <a href="https://wordpress.org/themes/decode/" rel="noreferrer">Decode</a> parent theme.</p>
<p>But be that as it may, if I update my child theme CSS without updating either WP or the parent theme at the same time how can I bust it from caches?</p>

@dalbaeb's comment eventually lead to insightful discussions and a feasible solution. Thanks a lot!
I believe the reason my child theme CSS was loaded using `'ver=<parent-theme-version>` was because I had followed the [WP Codex on child themes](http://codex.wordpress.org/Child_Themes) 1:1. My `functions.php` contained this:
```
add_action('wp_enqueue_scripts', 'theme_enqueue_styles');
function theme_enqueue_styles() {
wp_enqueue_style('parent-style', get_template_directory_uri() . '/style.css');
}
```
The code I ended up using was first mentioned in <https://wordpress.stackexchange.com/a/182023/30783> but numerous sites on the Internet copy-pasted it (without giving proper credit).
```
// Making sure your child theme has an independent version and can bust caches: https://wordpress.stackexchange.com/a/182023/30783
// Filter get_stylesheet_uri() to return the parent theme's stylesheet
add_filter('stylesheet_uri', 'use_parent_theme_stylesheet');
// Enqueue this theme's scripts and styles (after parent theme)
add_action('wp_enqueue_scripts', 'my_theme_styles', 20);
function use_parent_theme_stylesheet()
{
// Use the parent theme's stylesheet
return get_template_directory_uri() . '/style.css';
}
function my_theme_styles()
{
$themeVersion = wp_get_theme()->get('Version');
// Enqueue our style.css with our own version
wp_enqueue_style('child-theme-style', get_stylesheet_directory_uri() . '/style.css',
array(), $themeVersion);
}
```

What is the advantage of explicitly including a composer.json file in my plugin if potential users of my plugin can already get it as a package through WPackagist?
|
TL;DR
=====
If you want to support Composer, adding a `composer.json` is better then just let WPackagist create a package for you.
There are several reasons, no one is *really* important, but considering that to create a `composer.json` does not require much effort, it probably worth it.
`composer.json` Benefits
========================
Below a non-exhaustive list of benefits of using `composer.json`.
Developer friendly
------------------
When you require a package, Composer looks into *repositories* to find that specific package. Packagist and WPackagist are 2 repositories.
The difference is that Packagist is always parsed by Composer, while WPackagist have to be manually added to the project `composer.json`.
To require a plugin on Packagist you need a single line in `composer.json`:
```
"require": {
"your-name/your-plugin-name":"1.*",
}
```
To require a plugin on WPackagist you need to also configure repositories:
```
"repositories":[
{
"type":"composer",
"url":"http://wpackagist.org"
}
],
"require": {
"your-name/your-plugin-name":"1.*",
}
```
This is also relevant when using command line, see
```
composer create-project your-name/your-plugin-name
```
VS
```
composer create-project wpackagist-plugin/your-plugin-name --repository-url=http://wpackagist.org
```
Performance
-----------
When a project contains more repositories, Composer pings **all of them** to find information about packages.
So adding WPackagist repository, slows down installation. Also consider that all the servers can be down, for any reson. It happen to much bigger companies than the one behind WPackagist, so every repository you add, it is an additional possible point of failure.
Configuration
-------------
On of the advantages of having a `composer.json` is that you can configure the way Composer will fetch your plugin.
For example, you can use configure the package name in the [`name`](https://getcomposer.org/doc/04-schema.md#name) property, instead of letting WPackagist create the package name for you.
Moreover there are a lot of configuration that can be done in `composer.json`, just some few examples:
* you can use the [`branch-alias`](https://getcomposer.org/doc/articles/aliases.md#branch-alias) setting to improve the compatibility of development version of the plugin
* even if you have no dependencies, you can use the [`require`](https://getcomposer.org/doc/04-schema.md#require) setting to set a minimum PHP version,
* the [`conflict`](https://getcomposer.org/doc/04-schema.md#conflict) setting let you explicit inform about conflicting packages...
and so on.
Ownership awareness
-------------------
When you require a plugin from WPackagist the "vendor" part of the package name is always `wpackagist-plugin`.
So people will require you plugin like:
```
"require": {
"wpackagist-plugin/your-plugin-name":"1.*",
}
```
If you put the plugin on packagist, you can use your own vendor prefix, and I think is better for marketing:
```
"require": {
"your-name/your-plugin-name":"1.*",
}
```
Autoload
--------
Composer provide autoload for packages. If you decide to use Composer, you can benefit of it. However, considering that you are shipping your plugin to official repo you need to take into account that the majority of your user will probably install your plugin not using Composer. It means that you have to possibilities:
* ship the "vendor" folder (that contains the autoload) insider your plugin folder in the official repo
* make use of a custom autoloader or a manual loading mechanism in case the plugin is used without Composer.
The second possibility is mentioned only because your plugin has no dependencies handled by Composer, otherwise ship vendor folder is the only possibility to make your plugin work without Composer, but is not issue-free: when different plugins are installed with embedded vendor folder there is the possibility of version conflicts if different plugins ships different version of same package.
Explicit Composer support
-------------------------
By adding `composer.json` you make people know that you explicitly support Composer. For example, when I search for a plugin, to find a `composer.json` in the plugin folder is a big plus for me, as I tend to don't use plugins that don't do that.
Moreover, there are tools that target plugin explictly supporting Composer.
For example, I have a script that prevents automatic updates for plugin / themes that have a `composer.json`.

Place the following code in your `meta.php` template file immediately after the lines where it prints the categories and tags. Please note, the standard practice is that you shall copy the `meta.php` template file to your theme folder. So to override `meta.php`, copy: **woocommerce/templates/single-product/meta.php** from plugin folder to **yourtheme/woocommerce/templates/single-product/meta.php**
```
<?php
global $product;
$downloads = $product->get_files();
foreach( $downloads as $key => $each_download ) {
$info = pathinfo($each_download["file"]);
$ext = $info['extension'];
$formats .= $ext . ", ";
}
echo '<p> Formats: '. $formats .'</p>';

I have a `<form>` with about 20 inputs (mostly `select` and `number`) which each is an argument in `WP_Query` if filled.

I have read quite a few of your posts and it seems like your queries are really complex which either slows the page or simply crashes it.
Transients are definitely an option to store the results of such labor intensive queries. As @s\_ha\_dum mentioned, you'll need to look into what you will be saving.

You need to remember that transients are quite expensive to create, so that is something that you would not want to do every hour like you have said. A transient should be created with expiry times that would make them useful, like set the deletion time to something like days or month.
Once created, checking and getting data from a transients simply means 2 db calls in less than 0.002 seconds, so you definitely gain quite a lot on really expensive operations.
Space should never be an issue in the db as you would only want to store post ID's and not the complete object. We want to store as little data in our transient as possible. It is going to mean that you would need to run a second query to get the post objects, but this query will be much leaner. The big score here would be that the first expensive query is dealt with and eliminated. The first query should also be much leaner because we would query id's only.
You can and must in situations where input data is dynamic, use the input data to create a dynamic transient name. You need to remember, a transient's name can only be 45 characters long. A name longer than 45 characters make that the transient is not created, and every page load tries to create a transient. As I said, transients are expensive to create and you do not want to create a transient on every page load as this will add even more load on an already overloaded query. I always pass my input data to `md5()` (*which generate a 32 character key*) to create a unique hashed key and then have a transient name like `some_name_{md5()_result}`. Just remember to convert arrays with `json_encode()` first and then use that result to pass to `md5()`. You can look into some of [these posts](https://wordpress.stackexchange.com/search?q=md5%20user%3Ame) to see examples using `md5()`.
What might be an issue here is the amount of transients you are going to create. If you have a possible 1 million dynamic input combinations, you are going to create 1 million transients which can have effects when you delete the transients. This can again cause an issue with crashing the back end.
If the input is dynamic, you are going to save empty values as well for queries where no posts are returned, so you would need to take that into consideration.
What really is also a big factor here is, what is the possibility of two or ten or hundred users using the same exact input values in a week. I mean, there are no usefulness in creating a transient if only one or two people are ever going to use the same exact input values. As I said, creating transients are expensive, so you would not want to unnecessarily create a transient just for one or two people
At the end of day, you will need to take this info and decide how useful or useless a transient would be and then act on that.
Here is just an idea if you wish to have transients
```
// Here is your string of inputs
$args = 'value-1=value&value-2=250000';
// Create a unique hashed key from the arguments
$key = md5( $args );
//$key = md5( json_encode( $args ) ); // If $args is an array
// Set the transient name
$transient_name = 'custom_input_' . $key;
if ( false === ( $query = get_transient( $transient_name ) ) ) {
$query = get_posts( $args . '&fields=ids' ) // Only get post ids. Alter if $args is an array
// Set the transient only if we have results
if ( $query )
set_transient(
$transient_name, // Transient name
$query, // What should be saved
7 * DAY_IN_SECONDS // Lifespan of transient is 7 days
);
}
// Now run the second query to get the full objects. Just add 'post_type' if this is not 'post' posts
if ( $query ) {
$args = [
'post__in' => $query,
'posts_per_page' => count( $query ),
'order' => 'ASC',
'orderby' => 'post_in'
];
$q = new WP_Query( $args );
var_dump( $q );
}
```
We can then just flush all transients when we publish a new post, deletes it, undelete or update a post
```
add_action( 'transition_post_status', function ()
{
global $wpdb;
$wpdb->query( "DELETE FROM $wpdb->options WHERE `option_name` LIKE ('_transient%_custom_input_%')" );
$wpdb->query( "DELETE FROM $wpdb->options WHERE `option_name` LIKE ('_transient_timeout%_custom_input_%')" );
});
```

The `edit_others_posts` capability should allow users to set the author of a post.
At first glance you might reply that you don't want your authors to be able to edit one another's posts. The difference in ability is very subtle though: writing a post and then assigning it to another user isn't much different from being able to write or edit that other user's posts.

I have googled for this and, did not find any solution.
I am trying to add Birth date (datepicker) field in woocommerce registration page.
The registration form has been created as per guidance posted [here](https://support.woothemes.com/hc/en-us/articles/203182373-How-to-add-custom-fields-in-user-registration-on-the-My-Account-page)
I am using datepicker script available [here](http://glad.github.io/glDatePicker/)
According to DatePicker documentation we have to add below code in order to make it work.
```
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script src="glDatePicker.min.js"></script>
<script type="text/javascript">
$(window).load(function()
{
$('input').glDatePicker();
});
</script>
```
Problem is all other fields in the form start displaying calendar. This is because the javascript adds calendar to all the 'input' fields of the form.
How to solve this???
Code in functions.php ....
```
<p class="form-row form-row-wide">
<label for="reg_billing_birthdate"><?php _e( 'Birth Date', 'woocommerce' ); ?> <span class="required">*</span></label>
<input type="text" class="input-text" name="billing_birthdate" id="reg_billing_birthdate" gldp-id="mydate" value="<?php if ( ! empty( $_POST['billing_birthdate'] ) ) esc_attr_e( $_POST['billing_birthdate'] ); ?>" />
</p>
```
|
Don't include jquery from any other source, it will create conflict. Bcoz jQuery is pre bundled in wordpress by default.
For your question, add an `id` or `class` to the input element then add the datepicker based on the class. For example
```
<input type="text" class="da_test" value="" >
<script type="text/javascript">
$(window).load(function()
{
$('.da_test').glDatePicker();
});
</script>
```
This will avoid datepicker to appear in every input element.

There could be many approaches to this. Mine is given below ..
1. First you store the time on which the user was logged in so that you can display the successfull login popup for X number of minutes ..
```
function store_login_time($user_login, $user) {
$userID = $user->ID;
update_user_meta( $userID, '_login_time_', time() );
}
add_action('wp_login', 'store_login_time', 10, 2);
```
2. Then you use this code to display the code on the front page of the website for X number of minutes ( 1 minute in my sample ) using `wp_head` action ..
```
function myscript() {
$to_time = time();
$from_time = get_user_meta( get_current_user_id(), '_login_time_', true );
$diff = round(abs($to_time - $from_time) / 60,2);
// This will run till 1 minute after logging in ..
// For Seconds use 0.1 to 0.9
if ( is_front_page() && $diff < "1" ){
?>
<script type="text/javascript">
$( document ).ready(function() {
$('<div class="item login">Success! You\'re now signed in.</div>').appendTo('.pop-notice').delay(6000).queue(function() { $(this).remove(); });
});
</script>
<?php
}
}
add_action('wp_head', 'myscript');
```
You can add further options for user roles as per you needs.

After several headaches i managed to solve the issue based on Milo's answer.
But i need to add a check if the excerpt returned empty, and if it return empty i need to trim the entire content string to get the desired data.
Final code:
```
function pegarConteudoPost()
{
if( is_single() || is_page() )
{
$this_page = get_queried_object();
$excerpt = get_post_field( 'post_excerpt', $this_page->ID );
if ($excerpt === '')
{
$excerpt = wp_trim_words(get_post_field( 'post_content', $this_page->ID ), 55);
}
$texto = $excerpt;
}
else
{
$texto = get_bloginfo('description');
}
return $texto;
}
```

<h2>The Problem</h2>
<p>WP appears to remove the value of my query variable before it gets used to filter the list of users.</p>
<h2>My Code</h2>
<p>This function adds a custom column to my Users table on <code>/wp-admin/users.php</code>:</p>
<pre><code>function add_course_section_to_user_meta( $columns ) {
$columns['course_section'] = 'Section';
return $columns;
}
add_filter( 'manage_users_columns', 'add_course_section_to_user_meta' );
</code></pre>
<p>This function tells WP how to fill values in the column:</p>
<pre><code>function manage_users_course_section( $val, $col, $uid ) {
if ( 'course_section' === $col )
return get_the_author_meta( 'course_section', $uid );
}
add_filter( 'manage_users_custom_column', 'manage_users_course_section' );
</code></pre>
<p>This adds a dropdown and <code>Filter</code> button above the Users table:</p>
<pre><code>function add_course_section_filter() {
echo '<select name="course_section" style="float:none;">';
echo '<option value="">Course Section...</option>';
for ( $i = 1; $i <= 3; ++$i ) {
if ( $i == $_GET[ 'course_section' ] ) {
echo '<option value="'.$i.'" selected="selected">Section '.$i.'</option>';
} else {
echo '<option value="'.$i.'">Section '.$i.'</option>';
}
}
echo '<input id="post-query-submit" type="submit" class="button" value="Filter" name="">';
}
add_action( 'restrict_manage_users', 'add_course_section_filter' );
</code></pre>
<p>This function alters the user query to add my <code>meta_query</code>:</p>
<pre><code>function filter_users_by_course_section( $query ) {
global $pagenow;
if ( is_admin() &&
'users.php' == $pagenow &&
isset( $_GET[ 'course_section' ] ) &&
!empty( $_GET[ 'course_section' ] )
) {
$section = $_GET[ 'course_section' ];
$meta_query = array(
array(
'key' => 'course_section',
'value' => $section
)
);
$query->set( 'meta_key', 'course_section' );
$query->set( 'meta_query', $meta_query );
}
}
add_filter( 'pre_get_users', 'filter_users_by_course_section' );
</code></pre>
<h2>Other Information</h2>
<p>It creates my dropdown correctly. When I select a course section and click <code>Filter</code> the page refreshes and <code>course_section</code> shows up in the URL, but it has no value associated with it. If I check the HTTP requests, it shows that it gets submitted with the correct variable value, but then there's a <code>302 Redirect</code> that seems to strip out the value I selected.</p>
<p>If I submit the <code>course_section</code> variable by typing it directly into the URL, the filter works as expected.</p>
<p>My code is roughly based on <a href="http://www.davemccourt.com/wp-user-filtering/" rel="noreferrer">this code from Dave Court</a>.</p>
<p>I also tried whitelisting my query var using this code, but with no luck:</p>
<pre><code>function add_course_section_query_var( $qvars ) {
$qvars[] = 'course_section';
return $qvars;
}
add_filter( 'query_vars', 'add_course_section_query_var' );
</code></pre>
<p>I'm using WP 4.4. Any ideas why my filter is not working?</p>

However, your code works correctly in version 4.3.1! </p>\n\n<p>I think this is a Wordpress bug. I don't know if it's been reported yet. I think the reason behind the bug might be that the submit button is sending the query vars twice. If you look at the query vars, you will see that course_section is listed twice, once with the correct value and once empty. </p>\n\n<h1>Edit: This is the JavaScript Solution</h1>\n\n<p>Simply add this to your theme’s functions.php file and change the NAME_OF_YOUR_INPUT_FIELD to the name of your input field! Since WordPress automatically loads jQuery on the admin side, you do not have to enqueue any scripts. This snippet of code simply adds a change listener to the dropdown inputs and then automatically updates the other dropdown to match the same value. <a href=\"http://www.linsoftware.com/using-the-restrict_manage_users-action-hook-in-wordpress-4-4/\" rel=\"nofollow\">More explanation here.</a></p>\n\n<pre><code>add_action( 'in_admin_footer', function() {\n?>\n<script type=\"text/javascript\">\n var el = jQuery(\"[name='NAME_OF_YOUR_INPUT_FIELD']\");\n el.change(function() {\n el.val(jQuery(this).val());\n });\n</script>\n<?php\n} );\n</code></pre>\n\n<p>Hope this helps! </p>\n"

"text": "<h2>UPDATE 2018-06-28</h2>\n\n<p>While the code below mostly works fine, here is a rewrite of the code for WP >=4.6.0 (using PHP 7):</p>\n\n<pre><code>function add_course_section_filter( $which ) {\n\n // create sprintf templates for <select> and <option>s\n $st = '<select name=\"course_section_%s\" style=\"float:none;\"><option value=\"\">%s</option>%s</select>';\n $ot = '<option value=\"%s\" %s>Section %s</option>';\n\n // determine which filter button was clicked, if any and set section\n $button = key( array_filter( $_GET, function($v) { return __( 'Filter' ) === $v; } ) );\n $section = $_GET[ 'course_section_' . $button ] ?? -1;\n\n // generate <option> and <select> code\n $options = implode( '', array_map( function($i) use ( $ot, $section ) {\n return sprintf( $ot, $i, selected( $i, $section, false ), $i );\n }, range( 1, 3 ) ));\n $select = sprintf( $st, $which, __( 'Course Section...' ), $options );\n\n // output <select> and submit button\n echo $select;\n submit_button(__( 'Filter' ), null, $which, false);\n}\nadd_action('restrict_manage_users', 'add_course_section_filter');\n\nfunction filter_users_by_course_section($query)\n{\n global $pagenow;\n if (is_admin() && 'users.php' == $pagenow) {\n $button = key( array_filter( $_GET, function($v) { return __( 'Filter' ) === $v; } ) );\n if ($section = $_GET[ 'course_section_' . $button ]) {\n $meta_query = [['key' => 'courses','value' => $section, 'compare' => 'LIKE']];\n $query->set('meta_key', 'courses');\n $query->set('meta_query', $meta_query);\n }\n }\n}\nadd_filter('pre_get_users', 'filter_users_by_course_section');\n</code></pre>\n\n<p>I incorporated several ideas from @birgire and @cale_b who also offers solutions below that are worth reading. Specifically, I:</p>\n\n<ol>\n<li>Used the <code>$which</code> variable that was added in <code>v4.6.0</code></li>\n<li>Used best practice for i18n by using translatable strings, e.g. <code>__( 'Filter' )</code></li>\n<li>Exchanged loops for the (more fashionable?) <code>array_map()</code>, <code>array_filter()</code>, and <code>range()</code></li>\n<li>Used <code>sprintf()</code> for generating the markup templates</li>\n<li>Used the square bracket array notation instead of <code>array()</code></li>\n</ol>\n\n<p>Lastly, I discovered a bug in my earlier solutions. Those solutions always favor the TOP <code><select></code> over the BOTTOM <code><select></code>. So if you selected a filter option from the top dropdown, and then subsequently select one from the bottom dropdown, the filter will still only use whatever value was up top (if it's not blank). This new version corrects that bug.</p>\n\n<h2>UPDATE 2018-02-14</h2>\n\n<p>This <a href=\"https://core.trac.wordpress.org/ticket/35307\" rel=\"noreferrer\">issue has been patched since WP 4.6.0</a> and the <a href=\"https://developer.wordpress.org/reference/hooks/restrict_manage_users/\" rel=\"noreferrer\">changes are documented in the official docs</a>. The solution below still works, though.</p>\n\n<h2>What Caused the Problem (WP <4.6.0)</h2>\n\n<p>The problem was that the <code>restrict_manage_users</code> action gets called twice: once ABOVE the Users table, and once BELOW it. This means that TWO <code>select</code> dropdowns get created with the <strong>same name</strong>. When the <code>Filter</code> button is clicked, whatever value is in the second <code>select</code> element (i.e. the one BELOW the table) overrides the value in the first one, i.e. the one ABOVE the table.</p>\n\n<p>In case you want to dive into the WP source, the <code>restrict_manage_users</code> action is triggered from within <a href=\"https://developer.wordpress.org/reference/classes/wp_users_list_table/extra_tablenav/\" rel=\"noreferrer\"><code>WP_Users_List_Table::extra_tablenav($which)</code></a>, which is the function that creates the native dropdown to change a user's role. That function has the help of the <code>$which</code> variable that tells it whether it is creating the <code>select</code> above or below the form, and allows it to give the two dropdowns different <code>name</code> attributes. Unfortunately, the <code>$which</code> variable doesn't get passed to the <code>restrict_manage_users</code> action, so we have to come up with another way to differentiate our own custom elements.</p>\n\n<p>One way to do this, as <a href=\"/a/213582/9800\">@Linnea suggests</a>, would be to add some JavaScript to catch the <code>Filter</code> click and sync up the values of the two dropdowns. I chose a PHP-only solution that I'll describe now.</p>\n\n<h2>How to Fix It</h2>\n\n<p>You can take advantage of the ability to turn HTML inputs into arrays of values, and then filter the array to get rid of any undefined values. Here's the code:</p>\n\n<pre class=\"lang-php prettyprint-override\"><code> function add_course_section_filter() {\n if ( isset( $_GET[ 'course_section' ]) ) {\n $section = $_GET[ 'course_section' ];\n $section = !empty( $section[ 0 ] ) ? $section[ 0 ] : $section[ 1 ];\n } else {\n $section = -1;\n }\n echo ' <select name=\"course_section[]\" style=\"float:none;\"><option value=\"\">Course Section...</option>';\n for ( $i = 1; $i <= 3; ++$i ) {\n $selected = $i == $section ? ' selected=\"selected\"' : '';\n echo '<option value=\"' . $i . '\"' . $selected . '>Section ' . $i . '</option>';\n }\n echo '</select>';\n echo '<input type=\"submit\" class=\"button\" value=\"Filter\">';\n }\n add_action( 'restrict_manage_users', 'add_course_section_filter' );\n\n function filter_users_by_course_section( $query ) {\n global $pagenow;\n\n if ( is_admin() && \n 'users.php' == $pagenow && \n isset( $_GET[ 'course_section' ] ) && \n is_array( $_GET[ 'course_section' ] )\n ) {\n $section = $_GET[ 'course_section' ];\n $section = !empty( $section[ 0 ] ) ? $section[ 0 ] : $section[ 1 ];\n $meta_query = array(\n array(\n 'key' => 'course_section',\n 'value' => $section\n )\n );\n $query->set( 'meta_key', 'course_section' );\n $query->set( 'meta_query', $meta_query );\n }\n }\n add_filter( 'pre_get_users', 'filter_users_by_course_section' );\n</code></pre>\n\n<h2>Bonus: PHP 7 Refactor</h2>\n\n<p>Since I'm excited about PHP 7, in case you're running WP on a PHP 7 server, here's a shorter, sexier version using the <a href=\"http://php.net/manual/en/migration70.new-features.php#migration70.new-features.null-coalesce-op\" rel=\"noreferrer\">null coalescing operator <code>??</code></a>:</p>\n\n<pre><code>function add_course_section_filter() {\n $section = $_GET[ 'course_section' ][ 0 ] ?? $_GET[ 'course_section' ][ 1 ] ?? -1;\n echo ' <select name=\"course_section[]\" style=\"float:none;\"><option value=\"\">Course Section...</option>';\n for ( $i = 1; $i <= 3; ++$i ) {\n $selected = $i == $section ?

The Problem
-----------
WP appears to remove the value of my query variable before it gets used to filter the list of users.
My Code
-------
This function adds a custom column to my Users table on `/wp-admin/users.php`:
```
function add_course_section_to_user_meta( $columns ) {
$columns['course_section'] = 'Section';
return $columns;
}
add_filter( 'manage_users_columns', 'add_course_section_to_user_meta' );
```
This function tells WP how to fill values in the column:
```
function manage_users_course_section( $val, $col, $uid ) {
if ( 'course_section' === $col )
return get_the_author_meta( 'course_section', $uid );
}
add_filter( 'manage_users_custom_column', 'manage_users_course_section' );
```
This adds a dropdown and `Filter` button above the Users table:
```
function add_course_section_filter() {
echo '<select name="course_section" style="float:none;">';
echo '<option value="">Course Section...</option>';
for ( $i = 1; $i <= 3; ++$i ) {
if ( $i == $_GET[ 'course_section' ] ) {
echo '<option value="'.$i.'" selected="selected">Section '.$i.'</option>';
} else {
echo '<option value="'.$i.'">Section '.$i.'</option>';
}
}
echo '<input id="post-query-submit" type="submit" class="button" value="Filter" name="">';
}
add_action( 'restrict_manage_users', 'add_course_section_filter' );
```
This function alters the user query to add my `meta_query`:
```
function filter_users_by_course_section( $query ) {
global $pagenow;
if ( is_admin() &&
'users.php' == $pagenow &&
isset( $_GET[ 'course_section' ] ) &&
!empty( $_GET[ 'course_section' ] )
) {
$section = $_GET[ 'course_section' ];
$meta_query = array(
array(
'key' => 'course_section',
'value' => $section
)
);
$query->set( 'meta_key', 'course_section' );
$query->set( 'meta_query', $meta_query );
}
}
add_filter( 'pre_get_users', 'filter_users_by_course_section' );
```
Other Information
-----------------
It creates my dropdown correctly. When I select a course section and click `Filter` the page refreshes and `course_section` shows up in the URL, but it has no value associated with it. If I check the HTTP requests, it shows that it gets submitted with the correct variable value, but then there's a `302 Redirect` that seems to strip out the value I selected.
If I submit the `course_section` variable by typing it directly into the URL, the filter works as expected.
My code is roughly based on [this code from Dave Court](http://www.davemccourt.com/wp-user-filtering/).
I also tried whitelisting my query var using this code, but with no luck:
```
function add_course_section_query_var( $qvars ) {
$qvars[] = 'course_section';
return $qvars;
}
add_filter( 'query_vars', 'add_course_section_query_var' );
```
I'm using WP 4.4. Any ideas why my filter is not working?
|
UPDATE 2018-06-28
-----------------
While the code below mostly works fine, here is a rewrite of the code for WP >=4.6.0 (using PHP 7):
```
function add_course_section_filter( $which ) {
// create sprintf templates for <select> and <option>s
$st = '<select name="course_section_%s" style="float:none;"><option value="">%s</option>%s</select>';
$ot = '<option value="%s" %s>Section %s</option>';
// determine which filter button was clicked, if any and set section
$button = key( array_filter( $_GET, function($v) { return __( 'Filter' ) === $v; } ) );
$section = $_GET[ 'course_section_' . $button ] ?? -1;
// generate <option> and <select> code
$options = implode( '', array_map( function($i) use ( $ot, $section ) {
return sprintf( $ot, $i, selected( $i, $section, false ), $i );
}, range( 1, 3 ) ));
$select = sprintf( $st, $which, __( 'Course Section...' ), $options );
// output <select> and submit button
echo $select;
submit_button(__( 'Filter' ), null, $which, false);
}
add_action('restrict_manage_users', 'add_course_section_filter');
function filter_users_by_course_section($query)
{
global $pagenow;
if (is_admin() && 'users.php' == $pagenow) {
$button = key( array_filter( $_GET, function($v) { return __( 'Filter' ) === $v; } ) );
if ($section = $_GET[ 'course_section_' . $button ]) {
$meta_query = [['key' => 'courses','value' => $section, 'compare' => 'LIKE']];
$query->set('meta_key', 'courses');
$query->set('meta_query', $meta_query);
}
}
}
add_filter('pre_get_users', 'filter_users_by_course_section');
```
I incorporated several ideas from @birgire and @cale\_b who also offers solutions below that are worth reading. Specifically, I:
1. Used the `$which` variable that was added in `v4.6.0`
2. Used best practice for i18n by using translatable strings, e.g. `__( 'Filter' )`
3. Exchanged loops for the (more fashionable?) `array_map()`, `array_filter()`, and `range()`
4. Used `sprintf()` for generating the markup templates
5. Used the square bracket array notation instead of `array()`
Lastly, I discovered a bug in my earlier solutions. Those solutions always favor the TOP `<select>` over the BOTTOM `<select>`. So if you selected a filter option from the top dropdown, and then subsequently select one from the bottom dropdown, the filter will still only use whatever value was up top (if it's not blank). This new version corrects that bug.
UPDATE 2018-02-14
-----------------
This [issue has been patched since WP 4.6.0](https://core.trac.wordpress.org/ticket/35307) and the [changes are documented in the official docs](https://developer.wordpress.org/reference/hooks/restrict_manage_users/). The solution below still works, though.
What Caused the Problem (WP <4.6.0)
-----------------------------------
The problem was that the `restrict_manage_users` action gets called twice: once ABOVE the Users table, and once BELOW it. This means that TWO `select` dropdowns get created with the **same name**. When the `Filter` button is clicked, whatever value is in the second `select` element (i.e. the one BELOW the table) overrides the value in the first one, i.e. the one ABOVE the table.
In case you want to dive into the WP source, the `restrict_manage_users` action is triggered from within [`WP_Users_List_Table::extra_tablenav($which)`](https://developer.wordpress.org/reference/classes/wp_users_list_table/extra_tablenav/), which is the function that creates the native dropdown to change a user's role. That function has the help of the `$which` variable that tells it whether it is creating the `select` above or below the form, and allows it to give the two dropdowns different `name` attributes. Unfortunately, the `$which` variable doesn't get passed to the `restrict_manage_users` action, so we have to come up with another way to differentiate our own custom elements.
One way to do this, as [@Linnea suggests](/a/213582/9800), would be to add some JavaScript to catch the `Filter` click and sync up the values of the two dropdowns. I chose a PHP-only solution that I'll describe now.
How to Fix It
-------------
You can take advantage of the ability to turn HTML inputs into arrays of values, and then filter the array to get rid of any undefined values. Here's the code:
```php
function add_course_section_filter() {
if ( isset( $_GET[ 'course_section' ]) ) {
$section = $_GET[ 'course_section' ];
$section = !empty( $section[ 0 ] ) ? $section[ 0 ] : $section[ 1 ];
} else {
$section = -1;
}
echo ' <select name="course_section[]" style="float:none;"><option value="">Course Section...</option>';
for ( $i = 1; $i <= 3; ++$i ) {
$selected = $i == $section ? ' selected="selected"' : '';
echo '<option value="' . $i . '"' . $selected . '>Section ' . $i . '</option>';
}
echo '</select>';
echo '<input type="submit" class="button" value="Filter">';
}
add_action( 'restrict_manage_users', 'add_course_section_filter' );
function filter_users_by_course_section( $query ) {
global $pagenow;
if ( is_admin() &&
'users.php' == $pagenow &&
isset( $_GET[ 'course_section' ] ) &&
is_array( $_GET[ 'course_section' ] )
) {
$section = $_GET[ 'course_section' ];
$section = !empty( $section[ 0 ] ) ? $section[ 0 ] : $section[ 1 ];
$meta_query = array(
array(
'key' => 'course_section',
'value' => $section
)
);
$query->set( 'meta_key', 'course_section' );
$query->set( 'meta_query', $meta_query );
}
}
add_filter( 'pre_get_users', 'filter_users_by_course_section' );
```
Bonus: PHP 7 Refactor
---------------------
Since I'm excited about PHP 7, in case you're running WP on a PHP 7 server, here's a shorter, sexier version using the [null coalescing operator `??`](http://php.net/manual/en/migration70.new-features.php#migration70.new-features.null-coalesce-op):
```
function add_course_section_filter() {
$section = $_GET[ 'course_section' ][ 0 ] ?? $_GET[ 'course_section' ][ 1 ] ?? -1;
echo ' <select name="course_section[]" style="float:none;"><option value="">Course Section...</option>';
for ( $i = 1; $i <= 3; ++$i ) {
$selected = $i == $section ? ' selected="selected"' : '';
echo '<option value="' . $i . '"' . $selected . '>Section ' . $i . '</option>';
}
echo '</select>';
echo '<input type="submit" class="button" value="Filter">';
}
add_action( 'restrict_manage_users', 'add_course_section_filter' );
function filter_users_by_course_section( $query ) {
global $pagenow;
if ( is_admin() && 'users.php' == $pagenow) {
$section = $_GET[ 'course_section' ][ 0 ] ?? $_GET[ 'course_section' ][ 1 ] ?? null;
if ( null !== $section ) {
$meta_query = array(
array(
'key' => 'course_section',
'value' => $section
)
);
$query->set( 'meta_key', 'course_section' );
$query->set( 'meta_query', $meta_query );
}
}
}
add_filter( 'pre_get_users', 'filter_users_by_course_section' );
```
Enjoy!

<p>I am working on a website that uses a previously developed image slider plugin. I had it all working in my local environment but once I took it live it kicked the following error anywhere the image slider is located...</p>
<pre><code>Warning: Missing argument 2 for wpdb::prepare(), called in
/home/content/r/o/b/robertrhuspeak/html/desarch/wp
content/plugins/portfolio/fields.php on line 48 and defined in
/home/content/r/o/b/robertrhuspeak/html/desarch/wp-includes/wp-db.php on line 1246
</code></pre>
<p>The line of code it is referencing looks like this...</p>
<pre><code>$fields = $wpdb->get_results($wpdb->prepare("SELECT meta_key, meta_value,
meta_order IS NULL AS isnull FROM $wpdb->postmeta WHERE post_id=$postID ORDER BY
isnull ASC, ABS(meta_order) ASC, meta_id"));
</code></pre>
<p>My understanding is that wp-db.php is expecting two arguments and the above code is not written with two arguments.</p>
<p>BUT, I frankly have no idea how it should be written. And I have dug hard on the Internet to find something that will explain it to me clearly.</p>
<p>Any guidance would be greatly appreciated.</p>
<p>Thanks!</p>

I am working on a website that uses a previously developed image slider plugin. I had it all working in my local environment but once I took it live it kicked the following error anywhere the image slider is located...
```
Warning: Missing argument 2 for wpdb::prepare(), called in
/home/content/r/o/b/robertrhuspeak/html/desarch/wp
content/plugins/portfolio/fields.php on line 48 and defined in
/home/content/r/o/b/robertrhuspeak/html/desarch/wp-includes/wp-db.php on line 1246
```
The line of code it is referencing looks like this...
```
$fields = $wpdb->get_results($wpdb->prepare("SELECT meta_key, meta_value,
meta_order IS NULL AS isnull FROM $wpdb->postmeta WHERE post_id=$postID ORDER BY
isnull ASC, ABS(meta_order) ASC, meta_id"));
```
My understanding is that wp-db.php is expecting two arguments and the above code is not written with two arguments.
BUT, I frankly have no idea how it should be written. And I have dug hard on the Internet to find something that will explain it to me clearly.
Any guidance would be greatly appreciated.
Thanks!

UPDATE 2018-06-28
-----------------
While the code below mostly works fine, here is a rewrite of the code for WP >=4.6.0 (using PHP 7):
```
function add_course_section_filter( $which ) {
// create sprintf templates for <select> and <option>s
$st = '<select name="course_section_%s" style="float:none;"><option value="">%s</option>%s</select>';
$ot = '<option value="%s" %s>Section %s</option>';
// determine which filter button was clicked, if any and set section
$button = key( array_filter( $_GET, function($v) { return __( 'Filter' ) === $v; } ) );
$section = $_GET[ 'course_section_' . $button ] ?? -1;
// generate <option> and <select> code
$options = implode( '', array_map( function($i) use ( $ot, $section ) {
return sprintf( $ot, $i, selected( $i, $section, false ), $i );
}, range( 1, 3 ) ));
$select = sprintf( $st, $which, __( 'Course Section...' ), $options );
// output <select> and submit button
echo $select;
submit_button(__( 'Filter' ), null, $which, false);
}
add_action('restrict_manage_users', 'add_course_section_filter');
function filter_users_by_course_section($query)
{
global $pagenow;
if (is_admin() && 'users.php' == $pagenow) {
$button = key( array_filter( $_GET, function($v) { return __( 'Filter' ) === $v; } ) );
if ($section = $_GET[ 'course_section_' . $button ]) {
$meta_query = [['key' => 'courses','value' => $section, 'compare' => 'LIKE']];
$query->set('meta_key', 'courses');
$query->set('meta_query', $meta_query);
}
}
}
add_filter('pre_get_users', 'filter_users_by_course_section');
```
I incorporated several ideas from @birgire and @cale\_b who also offers solutions below that are worth reading. Specifically, I:
1. Used the `$which` variable that was added in `v4.6.0`
2. Used best practice for i18n by using translatable strings, e.g. `__( 'Filter' )`
3. Exchanged loops for the (more fashionable?) `array_map()`, `array_filter()`, and `range()`
4. Used `sprintf()` for generating the markup templates
5. Used the square bracket array notation instead of `array()`
Lastly, I discovered a bug in my earlier solutions. Those solutions always favor the TOP `<select>` over the BOTTOM `<select>`. So if you selected a filter option from the top dropdown, and then subsequently select one from the bottom dropdown, the filter will still only use whatever value was up top (if it's not blank). This new version corrects that bug.
UPDATE 2018-02-14
-----------------
This [issue has been patched since WP 4.6.0](https://core.trac.wordpress.org/ticket/35307) and the [changes are documented in the official docs](https://developer.wordpress.org/reference/hooks/restrict_manage_users/). The solution below still works, though.
What Caused the Problem (WP <4.6.0)
-----------------------------------
The problem was that the `restrict_manage_users` action gets called twice: once ABOVE the Users table, and once BELOW it. This means that TWO `select` dropdowns get created with the **same name**. When the `Filter` button is clicked, whatever value is in the second `select` element (i.e. the one BELOW the table) overrides the value in the first one, i.e. the one ABOVE the table.
In case you want to dive into the WP source, the `restrict_manage_users` action is triggered from within [`WP_Users_List_Table::extra_tablenav($which)`](https://developer.wordpress.org/reference/classes/wp_users_list_table/extra_tablenav/), which is the function that creates the native dropdown to change a user's role. That function has the help of the `$which` variable that tells it whether it is creating the `select` above or below the form, and allows it to give the two dropdowns different `name` attributes. Unfortunately, the `$which` variable doesn't get passed to the `restrict_manage_users` action, so we have to come up with another way to differentiate our own custom elements.
One way to do this, as [@Linnea suggests](/a/213582/9800), would be to add some JavaScript to catch the `Filter` click and sync up the values of the two dropdowns. I chose a PHP-only solution that I'll describe now.
How to Fix It
-------------
You can take advantage of the ability to turn HTML inputs into arrays of values, and then filter the array to get rid of any undefined values. Here's the code:
```php
function add_course_section_filter() {
if ( isset( $_GET[ 'course_section' ]) ) {
$section = $_GET[ 'course_section' ];
$section = !empty( $section[ 0 ] ) ? $section[ 0 ] : $section[ 1 ];
} else {
$section = -1;
}
echo ' <select name="course_section[]" style="float:none;"><option value="">Course Section...</option>';
for ( $i = 1; $i <= 3; ++$i ) {
$selected = $i == $section ? ' selected="selected"' : '';
echo '<option value="' . $i . '"' . $selected . '>Section ' . $i . '</option>';
}
echo '</select>';
echo '<input type="submit" class="button" value="Filter">';
}
add_action( 'restrict_manage_users', 'add_course_section_filter' );
function filter_users_by_course_section( $query ) {
global $pagenow;
if ( is_admin() &&
'users.php' == $pagenow &&
isset( $_GET[ 'course_section' ] ) &&
is_array( $_GET[ 'course_section' ] )
) {
$section = $_GET[ 'course_section' ];
$section = !empty( $section[ 0 ] ) ? $section[ 0 ] : $section[ 1 ];
$meta_query = array(
array(
'key' => 'course_section',
'value' => $section
)
);
$query->set( 'meta_key', 'course_section' );
$query->set( 'meta_query', $meta_query );
}
}
add_filter( 'pre_get_users', 'filter_users_by_course_section' );
```
Bonus: PHP 7 Refactor
---------------------
Since I'm excited about PHP 7, in case you're running WP on a PHP 7 server, here's a shorter, sexier version using the [null coalescing operator `??`](http://php.net/manual/en/migration70.new-features.php#migration70.new-features.null-coalesce-op):
```
function add_course_section_filter() {
$section = $_GET[ 'course_section' ][ 0 ] ?? $_GET[ 'course_section' ][ 1 ] ?? -1;
echo ' <select name="course_section[]" style="float:none;"><option value="">Course Section...</option>';
for ( $i = 1; $i <= 3; ++$i ) {
$selected = $i == $section ? ' selected="selected"' : '';
echo '<option value="' . $i . '"' . $selected . '>Section ' . $i . '</option>';
}
echo '</select>';
echo '<input type="submit" class="button" value="Filter">';
}
add_action( 'restrict_manage_users', 'add_course_section_filter' );
function filter_users_by_course_section( $query ) {
global $pagenow;
if ( is_admin() && 'users.php' == $pagenow) {
$section = $_GET[ 'course_section' ][ 0 ] ?? $_GET[ 'course_section' ][ 1 ] ?? null;
if ( null !== $section ) {
$meta_query = array(
array(
'key' => 'course_section',
'value' => $section
)
);
$query->set( 'meta_key', 'course_section' );
$query->set( 'meta_query', $meta_query );
}
}
}
add_filter( 'pre_get_users', 'filter_users_by_course_section' );
```
Enjoy!

You can get the WooCommerce my-account URL as below
```
<a href="<?php echo get_permalink( get_option('woocommerce_myaccount_page_id') ); ?>" title="<?php _e('My Account',''); ?>"><?php _e('My Account',''); ?></a>
```
Now you can insert this in completed order mail template too.
```

I need your help, am trying to add class `dropdown-submenu` to a `<li>` element which has children. Not sure if I was clear enough, so here is an example:
```
|-Home (Parent Item)
|-Services (Parent Item) *class='dropdown'*
|-Orthodontics (Child Item) *** class="dropdown-submenu" ***
|-Invisalign (Sub Child Item)
|-Inman Aligner (Sub Child Item)
```
The HTML format is:
```
<!-- Services -->
<li class="dropdown active">
<a href="javascript:void(0);" class="dropdown-toggle" data-toggle="dropdown">
Services
</a>
<ul class="dropdown-menu">
<!-- Service Orthodontics -->
<li class="dropdown-submenu active">
<a href="javascript:void(0);">Orthodontics</a>
<ul class="dropdown-menu">
<li><a href="invisalign.html">Invisalign</a></li>
<li><a href="inman_aligner.html">Inman Aligner</a></li>
</ul>
</li>
<!-- End Service Orthodontics -->
```
My walker-class gives all `<li>` elements which has `<ul>` class `dropdown`. It simply look if the element has child and if true it set the class name to `dropdown`. Here is the code of `walker.php`
```
class Main_Walker_Nav_Menu extends Walker_Nav_Menu {
function start_lvl( &$output, $depth ){ //ul
$indent = str_repeat("\t",$depth);
$submenu = ($depth > 0) ? ' dropdown-menu' : '';
$output .= "\n$indent<ul class=\"dropdown-menu$submenu depth_$depth\">\n"; }
function start_el( &$output, $item, $depth = 0, $args = array(), $id = 0 ){ //li a span
$indent = ( $depth ) ? str_repeat("\t",$depth) : '';
$li_attributes = '';
$class_names = $value = '';
$classes = empty( $item->classes ) ? array() : (array) $item->classes;
$classes[] = ($args->walker->has_children) ? 'dropdown' : '';
$classes[] = ($item->current || $item->current_item_anchestor) ? 'active' : '';
$classes[] = 'menu-item-' . $item->ID;
if( $depth && $args->walker->has_children ){
$classes[] = 'dropdown-submenu';
}
$class_names = join(' ', apply_filters('nav_menu_css_class', array_filter( $classes ), $item, $args ) );
$class_names = ' class="' . esc_attr($class_names) . '"';
$id = apply_filters('nav_menu_item_id', 'menu-item-'.$item->ID, $item, $args);
$id = strlen( $id ) ? ' id="' . esc_attr( $id ) . '"' : '';
$output .= $indent . '<li' . $id . $value . $class_names . $li_attributes . '>';
$attributes = ! empty( $item->attr_title ) ? ' title="' . esc_attr($item->attr_title) . '"' : '';
$attributes .= ! empty( $item->target ) ? ' target="' . esc_attr($item->target) . '"' : '';
$attributes .= ! empty( $item->xfn ) ? ' rel="' . esc_attr($item->xfn) . '"' : '';
$attributes .= ! empty( $item->url ) ? ' href="' . esc_attr($item->url) . '"' : '';
$attributes .= ( $args->walker->has_children ) ? ' class="dropdown-toggle" data-toggle="dropdown"' : '';
$item_output = $args->before;
$item_output .= '<a' . $attributes . '>';
$item_output .= $args->link_before . apply_filters( 'the_title', $item->title, $item->ID ) . $args->link_after;
$item_output .= ( $depth == 0 && $args->walker->has_children ) ? '</a>' : '</a>';
$item_output .= $args->after;
$output .= apply_filters ( 'walker_nav_menu_start_el', $item_output, $item, $depth, $args );
}
```
Thanks in advance.

You can get the WooCommerce my-account URL as below
```
<a href="<?php echo get_permalink( get_option('woocommerce_myaccount_page_id') ); ?>" title="<?php _e('My Account',''); ?>"><?php _e('My Account',''); ?></a>
```
Now you can insert this in completed order mail template too.
```
<h2> <a href="<?php echo get_permalink( get_option('woocommerce_myaccount_page_id') ); ?>" title="<?php _e('My Account',''); ?>">Go to your account page for review</a> </h2>

<p>I read on the WP docs, <a href="https://gist.github.com/wpscholar/4947518" rel="nofollow">which pointed to this gist</a> that the correct way to enqueue styles for IE is by using the <code>$wp_styles</code>. I'm guessing that this would be true then for scripts as well.</p>
<h2>Take these examples for instance...</h2>
<p><strong>Option One</strong> - Using <code>wp_scripts</code> </p>
<pre><code>add_action('wp_print_scripts', function() {
global $wp_scripts;
wp_enqueue_script( 'html5shiv', 'https://oss.maxcdn.com/html5shiv/3.7.2/html5shiv.min.js', array( 'bootstrap' ) );
$wp_scripts->add_data( 'html5shiv', 'conditional', 'lt IE 9' );
} );
</code></pre>
<p><strong>Option Two</strong> - Use <code>wp_scripts</code> along with <code>is_IE</code> </p>
<pre><code>add_action('wp_print_scripts', function() {
global $wp_scripts, $is_IE;
if($is_IE) {
wp_enqueue_script( 'html5shiv', 'https://oss.maxcdn.com/html5shiv/3.7.2/html5shiv.min.js', array( 'bootstrap' ) );
$wp_scripts->add_data( 'html5shiv', 'conditional', 'lt IE 9' );
}
} );
</code></pre>
<p><strong>Option Three</strong> - Just echo it in the head :</p>
<pre><code>add_action('wp_head', function(){
echo '<!--[if lt IE 9]><script src="https://oss.maxcdn.com/html5shiv/3.7.2/html5shiv.min.js"></script><![endif]-->' . "\n";
});
</code></pre>
<p><strong>Option Four</strong> - Enqueue it to the head :</p>
<pre><code>add_action('wp_print_scripts', function(){
wp_enqueue_script( 'html5shiv', 'https://oss.maxcdn.com/html5shiv/3.7.2/html5shiv.min.js', array( 'bootstrap' ) );
});
</code></pre>
<p>The second option. seems cool because it looks a little cleaner on non-IE browsers. But I'm not sure if it actually has any speed advantage or if the check alone slows it down more. Other than that I can't seem to figure out any reason why option one is better than option 3 or 4.</p>
<hr>
<h2>The reason for this question</h2>
<p>I'm using the Genesis framework and <a href="https://gist.github.com/bryanwillis/0892fcec0b32c3ca64f2" rel="nofollow">they include HTML5shiv</a> like the example below which just didn't seem right to me:</p>
<pre><code>add_action( 'wp_head', 'genesis_html5_ie_fix' );
/**
* Load the html5 shiv for IE8 and below. Can't enqueue with IE conditionals.
*/
function genesis_html5_ie_fix() {
if ( ! genesis_html5() )
return;
echo '<!--[if lt IE 9]><script src="//html5shiv.googlecode.com/svn/trunk/html5.js"></script><![endif]-->' . "\n";
}
</code></pre>

"text": "<p>To extend on <strong>@gmazzap</strong> suggestion on not using globals when you can use <code>wp_scripts()</code>, there is a shortcut for <code>wp_scripts()</code> for adding conditional comments called <code>wp_script_add_data</code> and likewise <code>wp_style_add_data</code> for conditional styles. </p>\n\n<h2>So the correct way to use conditionals as of Wordpress 4.2 is like this:</h2>\n\n<pre><code>/**\n * IE enqueue HTML5shiv with conditionals\n * @link http://tiny.cc/html5shiv\n */\nfunction wpse_213701_enqueue_html5shiv() {\n wp_enqueue_script( 'html5shiv',\n 'https://oss.maxcdn.com/html5shiv/3.7.2/html5shiv.min.js',\n array(),\n false,\n false\n );\n wp_script_add_data( 'html5shiv', 'conditional', 'lt IE 9' );\n}\nadd_action('wp_enqueue_scripts', 'wpse_213701_enqueue_html5shiv');\n</code></pre>\n\n<p>However, the example above is using <em>HTML5shiv</em> which is a unique situation. Since it <strong>has to</strong> be loaded in the head you could do something like this next example if you're worried about a plugin like <a href=\"https://github.com/roots/soil\" rel=\"nofollow noreferrer\">Roots Soil</a> removing all the scripts from the head.</p>\n\n<hr>\n\n<p>Most likely you won't run into a situation like this though. It's a very unstable thing to do since a lot of scripts are required to load in the head. Putting scripts in the footer should be done by setting <a href=\"https://codex.wordpress.org/Function_Reference/wp_enqueue_script\" rel=\"nofollow noreferrer\"><code>$in_footer</code></a> variable to true when enqueuing scripts. So if you do use roots or any cache plugin for that matter don't plan on everything working exactly how you want right out of the box. </p>\n\n<p><em>Here's an ugly example of what you can do:</em></p>\n\n<pre><code>add_action( 'wp_head', 'wpse_213701_check_html5shiv', 1 );\nfunction wpse_213701_check_html5shiv() {\n remove_action( 'wp_head', 'genesis_html5_ie_fix' );\n if ( !has_filter( 'wp_head', 'wp_enqueue_scripts' ) && !wp_script_is( 'html5shiv', 'done' ) ) {\n add_action('wp_head', 'wpse_213701_echo_html5shiv');\n wp_dequeue_script('html5shiv');\n }\n}\nfunction wpse_213701_echo_html5shiv() {\n echo '<!--[if lt IE 9]><script src=\"https://oss.maxcdn.com/html5shiv/3.7.2/html5shiv.min.js\"></script><![endif]-->' . \"\\n\";\n}\n</code></pre>\n\n<hr>\n\n<p>This is overkill though and it still isn't a guarantee that it will work. Over the past 4 years <em>html5shiv</em> has taken on many names which has caused it to be registered / enqueued with several different handles (html5, html5shiv, html5shim, themename-html5shiv, html5-ie-fix, and html5-polyfill just to name a few). Additionally, it's often <a href=\"https://github.com/Modernizr/Modernizr/wiki/HTML5-Cross-Browser-Polyfills\" rel=\"nofollow noreferrer\">bundled with modernizr</a>.

I read on the WP docs, [which pointed to this gist](https://gist.github.com/wpscholar/4947518) that the correct way to enqueue styles for IE is by using the `$wp_styles`. I'm guessing that this would be true then for scripts as well.
Take these examples for instance...
-----------------------------------
**Option One** - Using `wp_scripts`
```
add_action('wp_print_scripts', function() {
global $wp_scripts;
wp_enqueue_script( 'html5shiv', 'https://oss.maxcdn.com/html5shiv/3.7.2/html5shiv.min.js', array( 'bootstrap' ) );
$wp_scripts->add_data( 'html5shiv', 'conditional', 'lt IE 9' );
} );
```
**Option Two** - Use `wp_scripts` along with `is_IE`
```
add_action('wp_print_scripts', function() {
global $wp_scripts, $is_IE;
if($is_IE) {
wp_enqueue_script( 'html5shiv', 'https://oss.maxcdn.com/html5shiv/3.7.2/html5shiv.min.js', array( 'bootstrap' ) );
$wp_scripts->add_data( 'html5shiv', 'conditional', 'lt IE 9' );
}
} );
```
**Option Three** - Just echo it in the head :
```
add_action('wp_head', function(){
echo '<!--[if lt IE 9]><script src="https://oss.maxcdn.com/html5shiv/3.7.2/html5shiv.min.js"></script><![endif]-->' . "\n";
});
```
**Option Four** - Enqueue it to the head :
```
add_action('wp_print_scripts', function(){
wp_enqueue_script( 'html5shiv', 'https://oss.maxcdn.com/html5shiv/3.7.2/html5shiv.min.js', array( 'bootstrap' ) );
});
```
The second option. seems cool because it looks a little cleaner on non-IE browsers. But I'm not sure if it actually has any speed advantage or if the check alone slows it down more. Other than that I can't seem to figure out any reason why option one is better than option 3 or 4.
---
The reason for this question
----------------------------
I'm using the Genesis framework and [they include HTML5shiv](https://gist.github.com/bryanwillis/0892fcec0b32c3ca64f2) like the example below which just didn't seem right to me:
```
add_action( 'wp_head', 'genesis_html5_ie_fix' );
/**
* Load the html5 shiv for IE8 and below. Can't enqueue with IE conditionals.
*/
function genesis_html5_ie_fix() {
if ( ! genesis_html5() )
return;
echo '<!--[if lt IE 9]><script src="//html5shiv.googlecode.com/svn/trunk/html5.js"></script><![endif]-->' . "\n";
}
```
|
To extend on **@gmazzap** suggestion on not using globals when you can use `wp_scripts()`, there is a shortcut for `wp_scripts()` for adding conditional comments called `wp_script_add_data` and likewise `wp_style_add_data` for conditional styles.
So the correct way to use conditionals as of Wordpress 4.2 is like this:
------------------------------------------------------------------------
```
/**
* IE enqueue HTML5shiv with conditionals
* @link http://tiny.cc/html5shiv
*/
function wpse_213701_enqueue_html5shiv() {
wp_enqueue_script( 'html5shiv',
'https://oss.maxcdn.com/html5shiv/3.7.2/html5shiv.min.js',
array(),
false,
false
);
wp_script_add_data( 'html5shiv', 'conditional', 'lt IE 9' );
}
add_action('wp_enqueue_scripts', 'wpse_213701_enqueue_html5shiv');
```
However, the example above is using *HTML5shiv* which is a unique situation. Since it **has to** be loaded in the head you could do something like this next example if you're worried about a plugin like [Roots Soil](https://github.com/roots/soil) removing all the scripts from the head.
---
Most likely you won't run into a situation like this though. It's a very unstable thing to do since a lot of scripts are required to load in the head. Putting scripts in the footer should be done by setting [`$in_footer`](https://codex.wordpress.org/Function_Reference/wp_enqueue_script) variable to true when enqueuing scripts. So if you do use roots or any cache plugin for that matter don't plan on everything working exactly how you want right out of the box.
*Here's an ugly example of what you can do:*
```
add_action( 'wp_head', 'wpse_213701_check_html5shiv', 1 );
function wpse_213701_check_html5shiv() {
remove_action( 'wp_head', 'genesis_html5_ie_fix' );
if ( !has_filter( 'wp_head', 'wp_enqueue_scripts' ) && !wp_script_is( 'html5shiv', 'done' ) ) {
add_action('wp_head', 'wpse_213701_echo_html5shiv');
wp_dequeue_script('html5shiv');
}
}
function wpse_213701_echo_html5shiv() {
echo '<!--[if lt IE 9]><script src="https://oss.maxcdn.com/html5shiv/3.7.2/html5shiv.min.js"></script><![endif]-->' . "\n";
}
```
---
This is overkill though and it still isn't a guarantee that it will work. Over the past 4 years *html5shiv* has taken on many names which has caused it to be registered / enqueued with several different handles (html5, html5shiv, html5shim, themename-html5shiv, html5-ie-fix, and html5-polyfill just to name a few). Additionally, it's often [bundled with modernizr](https://github.com/Modernizr/Modernizr/wiki/HTML5-Cross-Browser-Polyfills). With that in mind, if you think the above example is ridiculous, you're just as well off adding the script to `wp_head` in your child theme since a plugins *html5shiv* handle will most likely named something else.
Update (Moving scripts to footer with this approach) :
------------------------------------------------------
This sparked some action on [Roots/Soil](https://github.com/roots/soil/issues/33) Github page. Here's probably the best way to do this ( as suggested by [@grappler](https://wordpress.stackexchange.com/users/17937/grappler) ) and still move scripts to the footer. A similar approach was posted on [**@kaiser's**](https://wordpress.stackexchange.com/users/385/kaiser) [blog](http://unserkaiser.com/blog/2013/10/08/how-to-move-wordpress-core-javascript-to-the-footer/) a few years back.
```
function grappler_move_js_to_footer()
$scripts = wp_scripts();
foreach( $scripts->registered as $script ) {
if ( 'html5' == $script->handle ) {
wp_script_add_data( $script->handle, 'group', 0 );
} else {
wp_script_add_data( $script->handle, 'group', 1 );
}
}
}
add_action( 'wp_enqueue_scripts', 'grappler_move_js_to_footer', 99 );
```
---
As for what Mark Kaplan suggested and what **[toscho mentioned here](https://wordpress.stackexchange.com/a/213822/43806)** , **you shouldn't be using option 2's $is\_IE method**. Apparently, if the HTTP header Vary: User-Agent doesn't get sent, you will send the wrong output to users behind a cache causing it to break for those users. In regards to browser side detection [here is a long thread of examples](https://gist.github.com/padolsey/527683) on how that might be done. Even client-side detection has it's pitfalls.
---
At the end of the day, maybe the best answer is don't use any of these methods and forget about legacy browsers since [Microsoft has dropped support for them as of January 12](https://www.microsoft.com/en-us/WindowsForBusiness/End-of-IE-support).

<p>On the checkout page, on the Billing Details section, I added two custom fields: Alpha and Beta.
During checkout these fields are edited by the user and then saved together with the rest of his address info.</p>
<p>On the dashboard, on the "Edit User" page I also added these two custom fields: Alpha and Beta.</p>
<p>On the dashboard when I create an order (Woocommerce > Orders > Add Order) I select a customer. His Billing Details are automatically loaded into the "Billing Details" area.</p>
<p>Now I have to load also the values of the Alpha and Beta custom fields for that specific customer, into the "Custom Fields" area of the "Add New Order" page.</p>
<p>1 - How can I get the ID of that selected customer?</p>
<p>2 - Then, having the user ID how can I get the values of his Alpha and Beta fields and display them into the "Custom Fields" area of the "Add New Order" page?</p>
<p>The Order is not saved yet!</p>
<p>Thank you</p>

I want to delete all posts of a specific post type (in this case "vfb\_entry") that are older than 60 days. The cron job should run once a day.
I have the following code but it's not working if I trigger the cron job. However, running only the query in phpMyAdmin returns the correct result. So there must be an issue with the fuction itself.
Can anyone please help?
```
// Cron Job to Delete VFB Entries older than 60 days
if(!wp_next_scheduled( 'remove_old_vfb_entries')){
wp_schedule_event(time(), 'daily', 'remove_old_vfb_entries');
}
add_action('remove_old_vfb_entries', 'myd_remove_old_vfb_entries');
// Build the function
function myd_remove_old_vfb_entries(){
global $wpdb;
// Set max post date and post_type name
$date = date("Y-m-d H:i:s", strtotime('-60 days'));
$post_type = 'vfb_entry';
// Build the query
// Only select VFB Entries from LFG or LFM Form
$query = "
SELECT $wpdb->posts.ID FROM $wpdb->posts
WHERE post_type = '$post_type'
AND post_status = 'publish'
AND post_date < '$date'
AND ($wpdb->posts.ID IN (SELECT entry_id FROM wp_postmeta_lfg4 WHERE post_id IS NOT NULL) OR $wpdb->posts.ID IN (SELECT entry_id FROM wp_postmeta_lfm3 WHERE post_id IS NOT NULL))
ORDER BY post_modified DESC
";
$results = $wpdb->get_results($query);
foreach($results as $post){
// Let the WordPress API clean up the entire post trails
wp_delete_post( $post->ID, true);
}
}
```
**Edit:** Solution without querying my views, just using wp\_posts and wp\_postmeta and an INNER JOIN below.

```
// add the schedule event if it has been removed
if( ! wp_next_scheduled( 'mg_remove_old_entries' ) ) {
wp_schedule_event( time(), 'daily', 'mg_remove_old_entries' ); //run the event daily
}
// action hooked to fired with wordpress cron job
add_action( 'mg_remove_old_entries', 'mg_remove_old_entries' );
function mg_remove_old_entries() {
$posts = get_posts( [
'numberposts' => -1,
'post_type' => 'vfb_entry',
'date_query' => [
// get all the posts from the database which are older than 60 days
'before' => date( "Y-m-d H:i:s", strtotime( '-60 days' ) ),
],
]);
if( !empty($posts) ) {
foreach( $posts as $post ) {
wp_delete_post( $post->ID ); //remove the post from the database
}
}
}
```
**Note:** There is no need to run any custom sql query. It would make the query slow and also it is not good for wordpress. Wordpress has already in built functions for everything.

<p>I am trying to get only <strong>one</strong> post and this needs to be <strong>the latest one</strong> so here is what I am doing:</p>
<pre><code>$basic_args = $wp_query->query_vars;
$basic_args['tax_query'] = $wp_query->tax_query;
$aditional_args = array(
'post__in' => get_option('sticky_posts'),
'ignore_sticky_posts' => 1,
'order' => 'desc',
'post_status' => 'publish',
'posts_per_page' => 1
);
$normal_args = array_merge($basic_args, $aditional_args);
$normal_query = new WP_Query($normal_args);
$prev_post_ids = array();
if (!$normal_query->have_posts()) {
$normal_args = array_merge($basic_args, array('posts_per_page' => 1));
$normal_query = new WP_Query($normal_args);
}
echo $normal_query->post_count; // returns 25
if ($normal_query->have_posts()) {
while ($normal_query->have_posts()) {
....
// here I got 25 results instead of just one
}
}
</code></pre>
<p>I know that <code>posts_per_page</code> should be limit how many post I will get but is not working for me and don't know why. As you can read I am getting 25 post on the loop instead of one. Can any give me some advice around this topic? I have read <a href="https://wordpress.stackexchange.com/questions/181541/how-to-limit-the-number-of-posts-that-wp-query-gets">this</a> and <a href="https://codex.wordpress.org/Class_Reference/WP_Query" rel="nofollow noreferrer">this</a> but isn't helping at all.</p>
<p><strong>Update1</strong></p>
<p>I debug the <code>$normal_query->request</code> as suggested by <strong>@pieter-goosen</strong> and I am getting this <em>wrong</em> SQL query:</p>
<pre><code>SELECT SQL_CALC_FOUND_ROWS wp_posts.ID FROM wp_posts INNER JOIN wp_term_relationships ON (wp_posts.ID = wp_term_relationships.object_id) INNER JOIN wp_term_relationships AS tt1 ON (wp_posts.ID = tt1.object_id) WHERE 1=1 AND ( wp_term_relationships.term_taxonomy_id IN (6) AND tt1.term_taxonomy_id IN (6) ) AND wp_posts.post_type IN ('opinion', 'post', 'especiales') AND ((wp_posts.post_status = 'publish')) GROUP BY wp_posts.ID ORDER BY wp_posts.post_date DESC LIMIT 0, 25
</code></pre>
<p>Where the <code>LIMIT</code> is modified?</p>
<p><strong>Update2</strong></p>
<p>I have debug also the <code>$basic_args</code> which have <code>$wp_query->query_vars</code> and also <code>$normal_args</code> and here is the result:</p>
<pre><code>echo '<pre>';
print_r($basic_args);
echo '</pre>';

</code></pre>
<p>As you can see <code>post_per_page</code> is set to <code>1</code> here so why it's taking those 25?</p>
<p><strong>Update 3</strong></p>
<p>Apparently this is the problematic code at <code>functions.php</code>:</p>
<pre><code>function change_wp_search_size($query)
{
if ($query->is_search) {
$query->query_vars['posts_per_page'] = 25;
} // Change 25 to the number of posts you would like to show
return $query; // Return our modified query variables
}
add_filter('pre_get_posts', 'change_wp_search_size');
</code></pre>
<p>Shouldn't this works for search only? Why is acting over all query_vars all the time?</p>

I am trying to get only **one** post and this needs to be **the latest one** so here is what I am doing:
```
$basic_args = $wp_query->query_vars;
$basic_args['tax_query'] = $wp_query->tax_query;
$aditional_args = array(
'post__in' => get_option('sticky_posts'),
'ignore_sticky_posts' => 1,
'order' => 'desc',
'post_status' => 'publish',
'posts_per_page' => 1
);
$normal_args = array_merge($basic_args, $aditional_args);
$normal_query = new WP_Query($normal_args);
$prev_post_ids = array();
if (!$normal_query->have_posts()) {
$normal_args = array_merge($basic_args, array('posts_per_page' => 1));
$normal_query = new WP_Query($normal_args);
}
echo $normal_query->post_count; // returns 25
if ($normal_query->have_posts()) {
while ($normal_query->have_posts()) {
....
// here I got 25 results instead of just one
}
}
```
I know that `posts_per_page` should be limit how many post I will get but is not working for me and don't know why. As you can read I am getting 25 post on the loop instead of one. Can any give me some advice around this topic? I have read [this](https://wordpress.stackexchange.com/questions/181541/how-to-limit-the-number-of-posts-that-wp-query-gets) and [this](https://codex.wordpress.org/Class_Reference/WP_Query) but isn't helping at all.
**Update1**
I debug the `$normal_query->request` as suggested by **@pieter-goosen** and I am getting this *wrong* SQL query:
```
SELECT SQL_CALC_FOUND_ROWS wp_posts.ID FROM wp_posts INNER JOIN wp_term_relationships ON (wp_posts.ID = wp_term_relationships.object_id) INNER JOIN wp_term_relationships AS tt1 ON (wp_posts.ID = tt1.object_id) WHERE 1=1 AND ( wp_term_relationships.term_taxonomy_id IN (6) AND tt1.term_taxonomy_id IN (6) ) AND wp_posts.post_type IN ('opinion', 'post', 'especiales') AND ((wp_posts.post_status = 'publish')) GROUP BY wp_posts.ID ORDER BY wp_posts.post_date DESC LIMIT 0, 25
```
Where the `LIMIT` is modified?
**Update2**
I have debug also the `$basic_args` which have `$wp_query->query_vars` and also `$normal_args` and here is the result:
```
echo '<pre>';
print_r($basic_args);
echo '</pre>';

As you can see `post_per_page` is set to `1` here so why it's taking those 25?
**Update 3**
Apparently this is the problematic code at `functions.php`:
```
function change_wp_search_size($query)
{
if ($query->is_search) {
$query->query_vars['posts_per_page'] = 25;
} // Change 25 to the number of posts you would like to show
return $query; // Return our modified query variables
}
add_filter('pre_get_posts', 'change_wp_search_size');
```
Shouldn't this works for search only? Why is acting over all query\_vars all the time?
|
`pre_get_posts` alters all queries, back end and front end regardless.
There are two very important checks that a large amount of people misses, that is the `!is_admin()` check which only targets the front end, and then the most important check, `is_main_query()` which will only alter the main query and not custom queries.
You statement should look something like the follwoing
```
if ( !is_admin()
&& $query->is_main_query()
&& $query->is_search()
) {
// Your arguments to set
}
```

<p>I am building my first WP plugin, it should load some JS and CSS files only on specific pages selected through a form available in the plugin Admin area. Once selected in the form, Page Title gets stored in the DB wp_options table, then the data is pulled back out in a variable named $page_selected.
To load JS and CSS files only in the pages selected in form, I wanted to use the is_page() function, passing the $page_selected variable as a parameter.</p>
<pre><code> function my_custom_tooltip() {
if ( is_page($page_selected) ) {
wp_enqueue_style( 'custom_tooltip_frontend_css', plugins_url('custom-image-tooltip/custom-image-tooltip.css') );

}
} add_action('wp_enqueue_scripts', 'my_custom_tooltip');
</code></pre>
<p>Unluckily In my case that conditional statement doesn't work correctly. Is there any way to achieve the same result, matching the page selected in the form by the user with the current Page being displayed?</p>

If `$page_selected` returns a string containing the page title, it should work fine. I have tested it and `is_page()` accepts page title, page ID and the slug.
If you are facing issues, it will be better to store page ID in the database and use it with `is_page()`
Please refer to <https://codex.wordpress.org/Function_Reference/is_page> for more details on the possible arguments that can be passed to this conditional statement.

to answer the question: this is not possible.
AFAIK, (HTMLwise) there's no way to add a placeholder to select tags.
A lot of devs I know however tend to use `disabled selected` combination for the option...
```html
<select>
<option value="" disabled selected>Select your option</option>
<option value="ydasdas">ydasdas</option>
<option value="dasda">dasda</option>
<option value="ydagfdsdas">ydagfdsdas</option>
<option value="ewefsdf">ewefsdf</option>
</select>
```
[demo](https://jsfiddle.net/9amo84jd/)
I have checked CF7's source code (version 4.3.1), and there's no easy way we can achieve this html format.
You can go the hard way by removing `wpcf7_add_shortcode_select` action on `wpcf7_init` and add yours instead.

<p>I just bought the Visual Composer plugin from wpbakery, my problem is that I'm making ajax calls to get the content of posts that have been edited with Visual Composer when I get the data it only show me the shortcodes of the plugin</p>
<p>As I see from the information that I have found on how to fix this problem is that ajax calls can't show shortcodes because of the admin ajax url that they dont have full access to wordpress enviornment but I want to know if someone has done it please it would help me a lot</p>
<p>basically this is how I print it, the ajax call is working fine it shows me what I saved but the elements doesnt show correctly it only shows shortcodes</p>
<p>this code is in a plugin I made</p>
<pre><code>function prefix_load_proyect () {

$content = apply_filters('the_content', $post->post_content);
$content = do_shortcode(get_post_field('post_content', $postid));
$html=$content;
endwhile;
wp_reset_postdata();
echo $html;
die();
}
</code></pre>
<p>then in the js file I just make the ajax call and put the html response with jquery into a container</p>
<pre><code> jQuery.ajax({

Since Visual Composer Version 4.9 you have to use WPBMap::addAllMappedShortcodes() before the apply\_filters('the\_content', ...) or do\_shortcode(). You don't need both by the way, because apply\_filters('the\_content', ...) executes do\_shortcode() anyway.
Your function would then be:
```
function prefix_load_proyect () {
$post_id = $_POST[ 'proyect' ];
$the_query = new WP_Query(array('p'=>$post_id, 'post_type' => 'home_portfolio'));
/* --- Necessary since Visual Compoer V 4.9 --- */
WPBMap::addAllMappedShortcodes();
while ( $the_query->have_posts() ) : $the_query->the_post();
$content .= apply_filters('the_content', $post->post_content);
endwhile;
echo $content;
wp_die(); // wp_die() instead of die() provides better integration with WordPress
}

How can I get a post's content by post id? I tried `get_page('ID');` to show content but it does not work.
|
You can do it multiple ways. Following are best two ways.
```
$post_id = 5// example post id
$post_content = get_post($post_id);
$content = $post_content->post_content;
echo do_shortcode( $content );//executing shortcodes
```
Another method
```
$content = get_post_field('post_content', $post_id);
echo do_shortcode( $content );//executing shortcodes
```
After Pieter Goosen suggestion on `apply_filters`.
You can use `apply_filters` if you wanted the content to be filtered by other plugins. So this eliminates the need to use `do_shortcode`
Example
```
$post_id = 5// example post id
$post_content = get_post($post_id);
$content = $post_content->post_content;
echo apply_filters('the_content',$content);
//no need to use do_shortcode, but content might be filtered by other plugins.
```
If you don't want to allow other plugins to filter this content and need shortcode function then go with `do_shortcode`.
If you don't want shortcode too then just play with the `post_content`.

How can I execute DB queries when theme installs and delete those tables on theme uninstall?
|
Yes, you can accomplish it by WP default functionality. Let me explain it.
**1. While switch theme:**
There is a `switch_theme` action that runs right after the theme is switched. switch\_theme is triggered when the blog's theme is changed. Specifically, it fires after the theme has been switched but before the next request. Theme developers should use this hook to do things when their theme is deactivated.
```
<?php add_action('switch_theme', 'theme_deactivation_function'); ?>
```
Theme functions attached to this hook are only triggered in the theme being deactivated. To do things when your theme is activated, use `after_switch_theme`.
Delete a theme's options after deactivation:
```
add_action('switch_theme', 'mytheme_setup_options');
function mytheme_setup_options () {
delete_option('mytheme_enable_features');
delete_option('mytheme_enable_catalog');
}
```
`switch_theme` will only be called when your theme is *de-activated*.
**2. After switch theme:**
Theme functions attached to this hook are only triggered in the theme (and/or child theme) being activated. To do things when your theme is deactivated, use `switch_theme`.
In other words, the after\_setup\_theme represents the point at which *WordPress* sets up the current Theme, not the point at which the administrator activates and/or configures the current Theme.
```
<?php add_action("after_switch_theme", "mytheme_do_something"); ?>
```
Add options for your theme and set them to their default values:
```
add_action('after_switch_theme', 'mytheme_setup_options');
function mytheme_setup_options () {
add_option('mytheme_enable_catalog', 0);
add_option('mytheme_enable_features', 0);
}
```
`after_switch_theme` only fire when your theme is being activated.
**Referance:** `switch_theme` and `after_switch_theme` actions hook are located in [wp-includes/theme.php](https://core.trac.wordpress.org/browser/tags/4.4/src/wp-includes/theme.php#L0)

**How can i get the values before and after the update?**

First off you are using the function wrong. The function is tied to an action within wordpress whenever you use the `add_action` function. In this case you have added it to the `post_updated` action.
Basically your check\_values function gets added to a queue which will then get called by the action when its time to do the action.
You can see where the action gets called here: <https://core.trac.wordpress.org/browser/tags/4.4/src/wp-includes/post.php#L3359>
See line 3359 of this file. There is a function called `do_action` and its going to call all the functions tied to the post\_updated action. This would include your check\_values function. This is where your function is getting called and as you can see it passes in the necessary parameters for your function to interact with.
Try updating or adding a post. You should see some output there because this is when wordpress is calling your function.
Then in order to check to see if there was a change compare the two titles from the two before and after post objects
```
<?php
function check_values($post_ID, $post_after, $post_before){
if( $post_after->post_title !== $post_before->post_title ) {
// do something
}
}
add_action( 'post_updated', 'check_values', 10, 3 );
?>

Use [get\_the\_post\_thumbnail( $id, $size )](https://developer.wordpress.org/reference/functions/get_the_post_thumbnail/)
if you're going to echo the result.
And make sure you have post thumbs enabled.

<p>I'm coding a theme where I want to display information in the footer that's only available on a template page. I have been using <code>get_page_by_title()</code> which works well if you know what the page will be called, but in my opinion it's not very dynamic, it's impossible to predict what a user will name a page in your theme.</p>
<p>In my research I found a function called <code>get_all_page_ids()</code> which returns a numerically indexed array of ids from the site. This function would be a lot cooler if it was an associative (or even a post object), but I digress.</p>
<p>I have considered using something like this:</p>
<pre><code>$all_page_ids = get_all_page_ids();
foreach ($all_page_ids as $id) {
// get_post() {@link https://developer.wordpress.org/reference/functions/get_post/}
$post_object = get_post($id);
// preg_match() {@link http://php.net/manual/en/function.preg-match.php}
if(preg_match("/\b(contact)\b/i", $post_object->post_title)) {
// do something here
} else {
// for readability
continue;
}
}
</code></pre>
<p>However, this still creates the problem of having to know that the user chose to have the word contact in their title. What if they created a page called "Get in Touch" that is their contact page? This would break.</p>
<p>So, in short, my question revolves around best practice for theme designers. Is <code>get_page_by_title()</code> the <em>best</em> way to get another page's ID, or is there a way to combine a few functions/variables to get another page's ID without knowing the title?</p>
<p>Or are there WordPress functions that do this kind of heavy lifting or is <code>get_page_by_title()</code> the only close one? My suspicion is there's a hackier, but better way to do this, I just don't have any ideas. Thanks for any help you're able to give on this.</p>

I'm coding a theme where I want to display information in the footer that's only available on a template page. I have been using `get_page_by_title()` which works well if you know what the page will be called, but in my opinion it's not very dynamic, it's impossible to predict what a user will name a page in your theme.
In my research I found a function called `get_all_page_ids()` which returns a numerically indexed array of ids from the site. This function would be a lot cooler if it was an associative (or even a post object), but I digress.
I have considered using something like this:
```
$all_page_ids = get_all_page_ids();
foreach ($all_page_ids as $id) {
// get_post() {@link https://developer.wordpress.org/reference/functions/get_post/}
$post_object = get_post($id);
// preg_match() {@link http://php.net/manual/en/function.preg-match.php}
if(preg_match("/\b(contact)\b/i", $post_object->post_title)) {
// do something here
} else {
// for readability
continue;
}
}
```
However, this still creates the problem of having to know that the user chose to have the word contact in their title. What if they created a page called "Get in Touch" that is their contact page? This would break.
So, in short, my question revolves around best practice for theme designers. Is `get_page_by_title()` the *best* way to get another page's ID, or is there a way to combine a few functions/variables to get another page's ID without knowing the title?
Or are there WordPress functions that do this kind of heavy lifting or is `get_page_by_title()` the only close one? My suspicion is there's a hackier, but better way to do this, I just don't have any ideas. Thanks for any help you're able to give on this.

If you don't force a title, and obviously do not know the id, the only way you can do it is by letting the user select which page to use, usually done in the theme's options page, but can be done in the costumizer, or even as part of page editing

The image is getting pulled from an repeatable file field with an entry with an id of slide\_image\_id. I am have been looking around and have notice to use wp\_get\_attachment\_image\_url but when I use it with my above code the image does not display. Is there something I am doing wrong?

Unfortunately, the `wp_get_attachment_image()` function is currently (as of WordPress 4.4.1) hard-coded to output the `width` and `height` `<img>` attributes (see [ticket #14110](https://core.trac.wordpress.org/ticket/14110)), so you'll need to build the image markup yourself. This can be done by taking cues from [`wp_get_attachment_image()`'s source](https://core.trac.wordpress.org/browser/tags/4.4/src/wp-includes/media.php#L800):
```
<?php
$attachment = get_post( $entry['slide_image_id'] );
if( $attachment ) {
$img_size_class = 'full';
$img_atts = array(
'src' => wp_get_attachment_image_url( $entry['slide_image_id'], $img_size_class, false ),
'class' => 'attachment-' . $img_size_class . ' size-' . $img_size_class,
'alt' => trim(strip_tags( get_post_meta( $entry['slide_image_id'], '_wp_attachment_image_alt', true) ) )
);
//If an 'alt' attribute was not specified, try to create one from attachment post data
if( empty( $img_atts[ 'alt' ] ) )
$img_atts[ 'alt' ] = trim(strip_tags( $attachment->post_excerpt ));
if( empty( $img_atts[ 'alt' ] ) )
$img_atts[ 'alt' ] = trim(strip_tags( $attachment->post_title ));
$img_atts = apply_filters( 'wp_get_attachment_image_attributes', $img_atts, $attachment, $img_size_class );
echo( '<img ' );
foreach( $img_atts as $name => $value ) {

<p>I have posts in two languages, managed by WPML.</p>
<p>In one post, I share multiple links which are updated in a regular basis. Updating the same links for both languages is not an option (for now I only added this post in one language).</p>
<p>Which is the best way to define links text and URL only once, and reuse them in both languages?</p>
<p>I could code a shortcode and manage the links by code, but I would like to know if there is any plugin or other approach to accomplish this (I already did my research with no luck).</p>

I have posts in two languages, managed by WPML.
In one post, I share multiple links which are updated in a regular basis. Updating the same links for both languages is not an option (for now I only added this post in one language).
Which is the best way to define links text and URL only once, and reuse them in both languages?
I could code a shortcode and manage the links by code, but I would like to know if there is any plugin or other approach to accomplish this (I already did my research with no luck).

Your arguments for both [`wp_get_attachment_image_url()`](https://developer.wordpress.org/reference/functions/wp_get_attachment_image_url/) and [`wp_get_attachment_image()`](https://codex.wordpress.org/Function_Reference/wp_get_attachment_image) are in the wrong order - check the linked documentation for details. Additionally, `wp_get_attachment_image_url()` returns a URL - not an actual image element.

Unfortunately, the `wp_get_attachment_image()` function is currently (as of WordPress 4.4.1) hard-coded to output the `width` and `height` `<img>` attributes (see [ticket #14110](https://core.trac.wordpress.org/ticket/14110)), so you'll need to build the image markup yourself. This can be done by taking cues from [`wp_get_attachment_image()`'s source](https://core.trac.wordpress.org/browser/tags/4.4/src/wp-includes/media.php#L800):
```
<?php
$attachment = get_post( $entry['slide_image_id'] );
if( $attachment ) {
$img_size_class = 'full';
$img_atts = array(
'src' => wp_get_attachment_image_url( $entry['slide_image_id'], $img_size_class, false ),
'class' => 'attachment-' . $img_size_class . ' size-' . $img_size_class,
'alt' => trim(strip_tags( get_post_meta( $entry['slide_image_id'], '_wp_attachment_image_alt', true) ) )
);
//If an 'alt' attribute was not specified, try to create one from attachment post data
if( empty( $img_atts[ 'alt' ] ) )
$img_atts[ 'alt' ] = trim(strip_tags( $attachment->post_excerpt ));
if( empty( $img_atts[ 'alt' ] ) )
$img_atts[ 'alt' ] = trim(strip_tags( $attachment->post_title ));
$img_atts = apply_filters( 'wp_get_attachment_image_attributes', $img_atts, $attachment, $img_size_class );
echo( '<img ' );
foreach( $img_atts as $name => $value ) {
echo( $name . '="' . $value . '" ';
}
echo( '/>' );
}
?>

You should BIND the codes into action (you can use `plugins_loaded` for earliest stage):
```
add_action('plugins_loaded', 'my_func');
function my_func(){
// ======== HERE YOUR CODES =========//
}
```
p.s. you have to include the file correctly!
```
include_once(ABSPATH.'wp-includes/user.php');
```

<pre><code>$pages = get_pages(array("echo" => 0));

<p>But for the blog page it returns the wrong ID. It should be 1 (the blog page is automatically 1 if I understand it correctly) but instead it returns the ID of the actual page. </p>
<p>I've also tried the is_page() function, but that doesn't seem to work on objects.</p>
<p>Is there any way arround this issue?</p>

Do you have mod\_rewrite enabled?
This sort of thing tends to happen when it's not. At which point, you only have access to ugly permalinks (?p=N) or "almost pretty" permalinks (/index.php/slug). The latter uses pathinfo to get you the page you're requesting instead.
So I'd suggest double checking whether mod\_rewrite is installed and enabled. If it turns out it isn't, enable it and restart Apache.

You can check for if a user is logged in or not by `is_user_logged_in()` if logged in then show the page if not then redirect them. Perfect hook to use for this `template_redirect`.
Example
```
function check_and_redirect(){
if( is_page( 45 ) && !is_user_logged_in() ) {
wp_redirect( wp_login_url() );
exit();
}
}
add_action('template_redirect', 'check_and_redirect');
```
`is_page()` is used to check for specific pages, you can use page title, slug.

I'm trying to create a metabox in a custom post type. When I attempt to insert information into the Listing Price box and update the post, the information is not saved and disappears once the page reloads. Please take a look at my code below and let me know if you see anything that could be causing this issue. Thanks!
EDIT: I figured it out. I'm still not sure why my previous method wouldn't work. I changed the input field value to ID, 'listing\_price', true ); ?> and now the box updates!
```
<?php
function cns_add_custom_metabox(){
add_meta_box(
'cns_meta',
__('ForesTree Listing'),
'cns_meta_callback',
'listing',
'normal',
'high'
);
}
add_action( 'add_meta_boxes', 'cns_add_custom_metabox' );
function cns_meta_callback( $post ){
wp_nonce_field( basename(__FILE__), 'cns_listing_nonce' );
$cns_stored_meta = get_post_meta( $post->ID );
?>
<div>
<div class="meta-row">
<div class="meta-th">
<label for="listing-price" class="cns-row-title">Listing Price</label>
</div>
<div class="meta-td">
<input type="number" name="listing_price" id="listing-price" value="<?php if ( ! empty ( $cns_stored_meta['listing_price'] ) ) { echo esc_attr( $cns_store_meta['listing_price'][0] ); } ?>"/>
</div>
</div>
<div class="meta-row">
<div class="meta-th">
<span>Listing Description</span>
</div>
</div>
<div class="meta-editor"></div>
<?php
$content = get_post_meta( $post->ID, 'listing_description', true );
$editor_id = 'listing_description';
$settings = array(
'textarea_rows' => 8,
'media_buttons' => false
);
wp_editor( $content, $editor_id, $settings );
?>
</div>
<?php
}
function cns_meta_save( $post_id ) {
// Checks save status
$is_autosave = wp_is_post_autosave( $post_id );
$is_revision = wp_is_post_revision( $post_id );
$is_valid_nonce = ( isset( $_POST[ 'cns_listing_nonce' ] ) && wp_verify_nonce( $_POST[ 'cns_listing_nonce' ], basename(__FILE__) ) ) ? 'true' : 'false';
// Exits script depending on save status
if( $is_autosave || $is_revision || !$is_valid_nonce ){
return;
}
if( isset( $_POST['listing_price'] ) ) {
update_post_meta( $post_id, 'listing_price', sanitize_text_field( $_POST[ 'listing_price' ] ) );
}
}
add_action( 'save_post', 'cns_meta_save' );
```

You can check for if a user is logged in or not by `is_user_logged_in()` if logged in then show the page if not then redirect them. Perfect hook to use for this `template_redirect`.
Example
```
function check_and_redirect(){
if( is_page( 45 ) && !is_user_logged_in() ) {
wp_redirect( wp_login_url() );
exit();
}
}
add_action('template_redirect', 'check_and_redirect');
```
`is_page()` is used to check for specific pages, you can use page title, slug.

<pre><code>get_terms($taxonomy, array('parent' => $parent));
</code></pre>
<p>This works for some parents and returns an empty array for others. I checked if a term with the parent ID exists and if the same ID is in the 'parent' field of the child term's taxonomy. Even copy-pasted directly from the database. Is there anything else? I don't see a difference between the parents that work and the ones that don't.</p>
<p>edit: All invisible terms appear the moment I add a new term via the dashboard. Turns out the problem was that there is a function <code>wp_insert_term()</code> for adding terms and I was using <code>$wpdb->insert</code> and manually inserting the term and the taxonomy, which makes a difference, somehow.</p>

Use [`wp_insert_term()`](https://codex.wordpress.org/Function_Reference/wp_insert_term) instead of `$wpdb->insert` for adding new terms.
