I'm assuming you already know how to get your popup video working, and you want to know how to make sure only people who aren't logged in see the video. You can add this to your template file (footer.php is probably best):
```
<?php
if (is_front_page() && !is_user_logged_in()) {
//video popup content
}
?>
```

Your loop on `page.php` doesn't loop through all the pages on the site. It loops though all the pages returned by the main query and stored in the `$wp_query` global variable, which is how all of the primary WordPress "pages" work including the post archive pages, category, tag pages, etc. For any one "page" only one page will be in the `$wp_query` global so you only see one.
While the details can get complicated, what happens with a page load in WordPress is that the `WP_Query` class gets instantiated fairly early and it parses the url being loaded and works out what posts to query. That information is shoved into the `wp_query` global variable and is accessed by numerous bits of code thereafter (which is why you don't really ever want to alter that variable manually or via `query_posts()`). It is a wildly complicated mechanism which you can see here: <https://core.trac.wordpress.org/browser/tags/4.3.1/src/wp-includes/query.php#L1448>

Your question and answer comes down to template hierarchy and how it works, and it is really really useful to know the basics here.
I'm not going to go into details as I will need to write a short story, but here are the basics:
* Wordpress uses a very strict hierarchy for loading templates on a specific page request. This hierarchy is known as the [template hierarchy](https://developer.wordpress.org/themes/basics/template-hierarchy/) which you will **have to** work through at your own pace. This hierarchy remains constant and never change, except if the core developers changes it in newer versions (*like the introduction of some new extra templates in versions 4.3 and 4.4*), or if it is changes via one of the template filters.
* Wordpress is coded in such a way that the only template you will ever need to display any page on is `index.php`. This template is the ultimate fallback template for any page request and is the template lowest in any given hierarchy. This will in all probability never change.
* The template highest in the hierarchy will be loaded first, if found, otherwise, the first available template lower down in the hierarchy will be loaded. As it goes, if no special template is found, Wordpress will always load `index.php`. Any other custom template can however be used in stead of these through the specific template filters provided
* Any other template in a specific hierarchy, except `index.php` (*which is a must-have template*), is the nice-to-have templates. They are only there for convenience and their usage are optional. These template only serves to create a specific look and feel on the front end of the site for a specific page request through special functions or CSS and/or JS effects.
To put everything in perspective, lets look at your specific case. Lets look at the [template hierarchy for single posts](https://developer.wordpress.org/themes/basics/template-hierarchy/#single-post)
>
> The single post template file is used to render a single post.
> WordPress uses the following path:
>
>
> 1. **`single-{post-type}-{slug}.php`** β (Since 4.4) First, WordPress looks for
> a template for the specific post. For example, if post type is product
> and the post slug is dmc-12, WordPress would look for
> single-product-dmc-12.php.
> 2. **`single-{post-type}.php`** β If the post type

> 3. **`single.php`** β
> WordPress then falls back to single.php.
> 4. **`singular.php`** β Then it falls
> back to singular.php.
> 5. **`index.php`** β Finally, as mentioned above,
> WordPress ultimately falls back to index.php.
>
>
>
As you can see, in the above hierarchy, `single.php` is a higher ranking template than `index.php`, and since `single.php` exist in your theme, Wordpress will always load `single.php`, and never `index.php` (*or even `singular.php`*) for a single post page (*except if this behavior is interfered with through the `single_template` filter*).

* Wordpress is coded in such a way that the only template you will ever need to display any page on is `index.php`. This template is the ultimate fallback template for any page request and is the template lowest in any given hierarchy. This will in all probability never change.
* The template highest in the hierarchy will be loaded first, if found, otherwise, the first available template lower down in the hierarchy will be loaded. As it goes, if no special template is found, Wordpress will always load `index.php`. Any other custom template can however be used in stead of these through the specific template filters provided
* Any other template in a specific hierarchy, except `index.php` (*which is a must-have template*), is the nice-to-have templates. They are only there for convenience and their usage are optional. These template only serves to create a specific look and feel on the front end of the site for a specific page request through special functions or CSS and/or JS effects.
To put everything in perspective, lets look at your specific case. Lets look at the [template hierarchy for single posts](https://developer.wordpress.org/themes/basics/template-hierarchy/#single-post)
>
> The single post template file is used to render a single post.
> WordPress uses the following path:
>
>
> 1. **`single-{post-type}-{slug}.php`** β (Since 4.4) First, WordPress looks for
> a template for the specific post. For example, if post type is product
> and the post slug is dmc-12, WordPress would look for
> single-product-dmc-12.php.
> 2. **`single-{post-type}.php`** β If the post type
> is product, WordPress would look for single-product.php.
> 3. **`single.php`** β
> WordPress then falls back to single.php.
> 4. **`singular.php`** β Then it falls
> back to singular.php.
> 5. **`index.php`** β Finally, as mentioned above,
> WordPress ultimately falls back to index.php.
>
>
>
As you can see, in the above hierarchy, `single.php` is a higher ranking template than `index.php`, and since `single.php` exist in your theme, Wordpress will always load `single.php`, and never `index.php` (*or even `singular.php`*) for a single post page (*except if this behavior is interfered with through the `single_template` filter*).

*FYI: This has been also posted [here](https://stackoverflow.com/questions/33202955/which-ways-can-be-used-to-log-in-to-wordpress) since I'm fairly new to this website and didn't know that the Wordpress part existed. Sorry for the repost.*
I'm currently trying to tighten the security for a website which is running on [wordpress](/questions/tagged/wordpress "show questions tagged 'wordpress'") (seperate installation, not on wordpress.org / .com). I have installed [Wordfence](https://wordpress.org/plugins/wordfence/) which blocks all IPs which try to use a invalid user name instantly which works quite well (some 200+ blocked IPs / day).
Since our ISP is giving out hostnames like
```
www-xxx-yyy-zzz.my.isp.tld
```
and there are no users which need log in besides me I thought I would add some way to further prevent brute-force attacks.
The WP Codex has a [section about preventing access to wp-login.php](https://wordpress.org/support/article/brute-force-attacks/#deny-access-to-no-referrer-requests) for anyone who's not submitting it the form. In my eyes this should get rid of any scripts which try to brute force their way in like:
```
www.mydomain.tld/wp-admin.php?log=admin&pwd=alex
```
Now for anyone submitting the form this wouldn't work, so I added a part to the top of `wp-login.php` which would check for the host name and then re-direct if it doesn't match our ISP:
```
<?PHP
if (strpos(gethostbyaddr($_SERVER['REMOTE_ADDR']),'my.isp.tld') == false) {
header('Location: http://www.google.com/');
}
?>
```
I checked it and this piece is working fine as well, when I try to access `wp-login.php` over my mobile it throws me back to Google, additionally I get an e-mail when somebody tries this. So far it's only been 3-4 login attempts I prevented using this method.
Now from my perspective I've taken care of all things, but Wordfence will still send me notifications about blocked log-in attempts.
To see if it helps, I've added the following to the [.htaccess](/questions/tagged/.htaccess "show questions tagged '.htaccess'") file which is in the main Wordpress folder, which, to my understanding, should deny all access except when coming from my ISP:
```
<Files "wp-login.php">
order deny,allow
allow from my.isp.tld
</Files>
```
Still the e-mails come flying in. Now the question is:
Is there any other way to call `wp-login.php` in order to try to login which I haven't tought of? It seems that there are still ways which can be used which are not part of the scenarios mentioned above.
As commented in the other question: The IPs with the failed attempts are not spoofed to fit mine.

The answer to my question about other login possibilities was given in [the question posted by birgire](https://wordpress.stackexchange.com/questions/204485/brute-force-attack-even-though-it-is-limited-by-ip).
It turns out that after disabling any remote access to `xmlrpc.php` the attacks went down to zero.
However this might have [serious consequences](https://wordpress.org/support/topic/disabling-xml-rpc-may-damage-jetpack) on your website since it's used by e.g. [jetpack](/questions/tagged/jetpack "show questions tagged 'jetpack'") amongst others and I therefor not recommend it.
As mentioned by Mark Kaplun there are probably other, more serious attacks out there and from analyzing my logs these brute force attacks I've encountered are very basic and wouldn't stand a chance when you did the following:
* Change the admin user name to anything else than "admin"
* Use proper passwords

I tried to add PHP code after the post title in single post pages by adding a filter to `functions.php`, but this did not work:
```
function theme_slug_filter_the_content( $content ) {

$custom_content .= $content;

}
add_filter( 'the_content', 'theme_slug_filter_the_content' );

You need to use `the_title` filter, not `the_content`.
Also make sure you have `the_title()` function somewhere in your single post page.
Here is the code:
```
function theme_slug_filter_the_content( $title ) {
$custom_title = 'MY CODES';
$custom_title .= $title ;
return $custom_title ;
}
add_filter( 'the_title', 'theme_slug_filter_the_content' );

<p>because it doesn't fit my need, I have to add the logout link as a dropdown menu not as parent menu and also will show up in certain pages only. I can hel these things if anyone can show me the way how to fetch the <code>wp_logout_url()</code> data within the wp menu creation page.</p>

Add submenu with a custom link, `/wp-login?action=logout`, like the image below:
[](https://i.stack.imgur.com/Aw4k3.png)
Add code like below in `functions.php`:
```
function wpa_remove_menu_item( $items, $menu, $args ) {
if ( is_admin() || ! is_user_logged_in() )
return $items;
foreach ( $items as $key => $item ) {
if ( 'Login / Register' == $item->title )
unset( $items[$key] );
if ( 'Logout' == $item->title ) {
$items[$key]->url = wp_logout_url();
}
}
return $items;
}
add_filter( 'wp_get_nav_menu_items', 'wpa_remove_menu_item', 10, 3 );

"text": "<p>This is a really tricky and long question, there is no easy way to do this, as I guess you want to override this core WordPress function from within your theme.</p>\n\n<p>The way to go is a particular case of something <a href=\"https://wordpress.stackexchange.com/questions/33207/modify-a-output-of-a-widget\">explained here</a>, so you can do the following in your <code>functions.php</code>.</p>\n\n<p>Create a new class by copying the code from the <a href=\"https://core.trac.wordpress.org/browser/tags/4.3.1/src/wp-includes/default-widgets.php#L0\" rel=\"nofollow noreferrer\">original source</a>.

IΒ΄m having some difficulty override to default category widgets in my wordpress theme. I created the theme from scratch.
I want to remove the `<ul><li></li></ul>` from categories in the lists. I want to add my own style using `<a href=""></a>` instead
```
<div class="list-group">
<a href="#" class="list-group-item">LifeStyle</a>
<a href="#" class="list-group-item">SmartPhones</a>
<a href="#" class="list-group-item">Business</a>
<a href="#" class="list-group-item">Graphic Design</a>
<a href="#" class="list-group-item">Agriculture</a>
<a href="#" class="list-group-item">Music</a>
<a href="#" class="list-group-item">Travel</a>
```
I can override it?
|
This is a really tricky and long question, there is no easy way to do this, as I guess you want to override this core WordPress function from within your theme.
The way to go is a particular case of something [explained here](https://wordpress.stackexchange.com/questions/33207/modify-a-output-of-a-widget), so you can do the following in your `functions.php`.
Create a new class by copying the code from the [original source](https://core.trac.wordpress.org/browser/tags/4.3.1/src/wp-includes/default-widgets.php#L0). Give it a new name (in this example I will be using `WP_Widget_Categories_Modified`), and start modifying it.
After that you need to *unregister* the original Widget and *register* the new one (so, again, assuming your new class is named `WP_Widget_Categories_Modified`):
```
function replace_default_wp_widgets() {
unregister_widget( 'WP_Widget_Categories' );
register_widget( 'WP_Widget_Categories_Modified' );
}
add_action( 'widgets_init', 'replace_default_wp_widgets', 1 );
```
Now, you have replaced the default class with the new one, which is exactly the same as the original. So you need to start modifying the new class you created.
First of all, delete the `<ul>` and `</ul>` before and after `wp_list_categories` in your new Class (remember you copied the original code).
Since the WordPress original class calls to `wp_list_categories`, which includes the code, the best choice is to add a custom 'walker' to the function.
To do so, also add in your `functions.php` the walker, for instance:
```
class Walker_Categories_Plain extends Walker {
var $db_fields = array( 'parent' => 'parent_id', 'id' => 'object_id' );
function start_el( &$output, $item, $depth = 0, $args = array() ) {
$output .= "\n<a href='" . get_term_link( $item ) . "'>" . $item->name . "</a>\n";
}
}
```
Then, you need to pass this walker to `wp_list_categories`. To do this, add this argument as this, **before** the call to `wp_list_categories()`:
```
$cat_args['walker'] = new Walker_Categories_Plain;
```
That's it, it should work if I did not forget anything!
The walker can be modified to change the output until you reach your desired code (check the `$output` string).
Now, your theme:
1. Hides the default Category Widget
2. Registers its own Category Widget (which is only used to delete the `<ul>` and to pass the new Walker by default)
3. Creates its custom Walker (may be used anywhere else to modify `wp_list_categories`)

<p>As you can see in the post title at <a href="http://fosit.staging.wpengine.com/" rel="nofollow">http://fosit.staging.wpengine.com/</a>, when the post title gets to the margin it doesn't continue on a new line; it continues on the <em>same</em> line.</p>
<p>I don't know if this problem is native to twenty twelve or if it's due a change I made to the child theme (like when I moved the date of the post from after the post to under the title).</p>
<p>Any ideas?</p>

The issue is due to addition of following line in your child theme. There should be some line height to show header properly.
```
.entry-header .entry-title {
font-size: 1.6000rem; /* was 1.42857rem; */
font-weight: normal;
line-height: 0; /* changed from 1.2 */
}

<p>I came across vagrant, will it be useful? Also, how can I do version control?</p>
<p>I have decided to go with sub-domain development environment, as I am not expecting my freelancers to install whole website on local. Our website is too big with multisite setup, we have three teams at different location, one for design and other two for development. Also we are expanding our team now and then. So installing on local would not be suitable. I am going to use git and bitbucket. Can I create my master git repository directly from sub-domain development environment? How git setup would be ideally? Where should be my master repository and how many branches I should create?</p>

<?php
$meta = get_post_meta( get_the_ID(), 'Story' );
if( !empty($meta) ) {
echo $meta[0];
}?>
```
|
Try this:
```
if ( ! function_exists( 'customField' ) ) :
function customField($name, $id=false, $single=false){
global $post_type, $post;
$name=trim($name);
$prefix=''; // only if you need this
$data=NULL;
if($id!==false && !empty($id) && $id > 0)
$getMeta=get_post_meta((int)$id, $prefix.$name, $single);
else if(isset($post->ID) && $post->ID > 0)
$getMeta=get_post_meta($post->ID,$prefix.$name, $single);
else if('page' == get_option( 'show_on_front' ))
$getMeta=get_post_meta(get_option( 'page_for_posts' ),$prefix.$name, $single);
else if(is_home() || is_front_page() || get_queried_object_id() > 0)
$getMeta=get_post_meta(get_queried_object_id(),$prefix.$name, $single);
else
$getMeta=get_post_meta(get_the_id(),$prefix.$name, $single);
if(isset($getMeta[0])) $data=$getMeta[0];
if($data===false || !is_numeric($data) && (empty($data) || is_null($data))) return NULL;
$return = preg_replace(array('%<p>(<img .*?/>)</p>%i','%<p> </p>%i','/^\s*(?:<br\s*\/?>\s*)*/i'), array('$1','',''),$data);
return (!empty($return)?$return:NULL);
}
endif;
echo customField("story"); // Default
echo customField("story", 55); // With custom page ID
```
This code work great becouse I build this for my works. If return empty, in place where you setup pharameters, you not save your data. Also be careful about prefix of your metabox if you use it.

Adding below code to `wp-config.php` file will solve your problem:
```
if(is_admin()) {
add_filter('filesystem_method', create_function('$a', 'return "direct";' ));
define( 'FS_CHMOD_DIR', 0751 );
}
```
Above is quick fix I found on Wordpress support but problem is with permissions.
[For details please follow link](https://wordpress.org/support/topic/unable-to-locate-wordpress-content-directory-wp-content?replies=15)
Please check you permissions:
All FILES should have permissions set to 644
All DIRECTORIES (i.e. folders) should have permissions set to 755

|
There is a simple way using a default argument...
```
/*
* You need to get the IDs for the Categories you wish to include
*/
$args = array(
'category__and' => array( 1, 3 )
);
$the_query = new WP_Query( $args );
if ( $the_query->have_posts() )
{
// Do something to display your posts
...
} else
{
// no posts
}
wp_reset_postdata();
```

<p>I'm trying to create a category template in my theme that will display static content if the user is on the first page of the archive, and then display the posts in the category on the following pages. I'm basically trying to replicate the category behavior on Wired.com where <a href="http://www.wired.com/category/design">http://www.wired.com/category/design</a> is a landing page while /category/design/page/1 shows a reverse chronological listing of posts like you would expect on a category archive.</p>
<p>The key here is that I'm not showing any posts from the category archive on the first page, so I need the next page to start with the first post. I first tried doing this using <a href="https://codex.wordpress.org/Making_Custom_Queries_using_Offset_and_Pagination">offset and manual pagination</a> by setting the offset of the query to 0 if the 'paged' query var was 2. But offset is ignored when it's set to zero, so the best I can do is set the offset to 1 and start with the second post in the category.</p>
<p>This is what I added to functions.php:</p>
<pre><code>add_action('pre_get_posts', 'category_query_offset', 1 );
function category_query_offset(&$query) {
// Before anything else, make sure this is the right query
if (!$query->is_category('news')) {
return;
}
// Next, determine how many posts per page
$ppp = get_option('posts_per_page');
//Next, detect and handle pagination
if ($query->is_paged) {
// Manually determine page query offset
$page_offset = (($query->query_vars['paged']-1) * $ppp) - $ppp;
// Apply adjust page offset
$query->set('offset', $page_offset );
}
}
</code></pre>
<p>What would be better, and what it appears <em>Wired</em> does, is to use the default pagination so the posts start on page 1, but insert a page 0 for the static content. Hypothetically, this seems like it would be possible by displaying the static content if 'paged' is 0, and displaying the first page of posts if 'paged' is 1. The problem is that 'paged' is never 1 because Wordpress sets 'paged' to zero when the user requests the first page. That means 'paged' is 0 for both /category/news/page/1 and /category/news.</p>
<p>Is there a way to check if the user requested /category/news/page/1 as opposed to /category/news? Failing that, is there a way to display all the posts in the category starting on page 2?</p>

I'm trying to create a category template in my theme that will display static content if the user is on the first page of the archive, and then display the posts in the category on the following pages. I'm basically trying to replicate the category behavior on Wired.com where <http://www.wired.com/category/design> is a landing page while /category/design/page/1 shows a reverse chronological listing of posts like you would expect on a category archive.
The key here is that I'm not showing any posts from the category archive on the first page, so I need the next page to start with the first post. I first tried doing this using [offset and manual pagination](https://codex.wordpress.org/Making_Custom_Queries_using_Offset_and_Pagination) by setting the offset of the query to 0 if the 'paged' query var was 2. But offset is ignored when it's set to zero, so the best I can do is set the offset to 1 and start with the second post in the category.
This is what I added to functions.php:
```
add_action('pre_get_posts', 'category_query_offset', 1 );
function category_query_offset(&$query) {
// Before anything else, make sure this is the right query
if (!$query->is_category('news')) {
return;
}
// Next, determine how many posts per page
$ppp = get_option('posts_per_page');
//Next, detect and handle pagination
if ($query->is_paged) {
// Manually determine page query offset
$page_offset = (($query->query_vars['paged']-1) * $ppp) - $ppp;
// Apply adjust page offset
$query->set('offset', $page_offset );
}
}
```
What would be better, and what it appears *Wired* does, is to use the default pagination so the posts start on page 1, but insert a page 0 for the static content. Hypothetically, this seems like it would be possible by displaying the static content if 'paged' is 0, and displaying the first page of posts if 'paged' is 1. The problem is that 'paged' is never 1 because Wordpress sets 'paged' to zero when the user requests the first page. That means 'paged' is 0 for both /category/news/page/1 and /category/news.
Is there a way to check if the user requested /category/news/page/1 as opposed to /category/news? Failing that, is there a way to display all the posts in the category starting on page 2?

This is quite an interesting question (*which I have upvoted, specially for your approach and research*). The big curveball here is the first page of the query:
* You cannot set the query to return `0` posts on the first page
* By moving the page content of every page up by one page, you will loose the last page as the query will still only have the same amount of posts so the `$max_num_pages` property will still remain the same
We will need to somehow "trick" the `WP_Query` class to return our posts corectly with the offset of one page, and also get the correct number of pages in order not to loose the last page in the query
Lets look at the following idea and try to put everything in code. Before we do, I would however like to raise a few notes here
IMPORTANT NOTES:
----------------
* Everything is untested, so it might be buggy. Make sure to test this locally with debug turned on
* The code requires at least PHP 5.3, any version below 5.3 will cause a fatal error. Note, if are still using any version below PHP 5.5, you should have upgraded long time ago already
* Modify and abuse the code as you see fit to suit your exact needs
THE LIGHTBULB IDEA:
-------------------
**WHAT WE WILL NEED**
In order to make everything work, we will need the following:
* The current page number being viewed
* The `posts_per_page` option set in reading settings
* Custom `offset`
* Modify the `$found_posts` property of the query to correct the `$max_num_pages` property
Pagination is `WP_Query` comes down a very simple few lines of code
```
if ( empty($q['nopaging']) && !$this->is_singular ) {
$page = absint($q['paged']);
if ( !$page )
$page = 1;
// If 'offset' is provided, it takes precedence over 'paged'.
if ( isset( $q['offset'] ) && is_numeric( $q['offset'] ) ) {
$q['offset'] = absint( $q['offset'] );
$pgstrt = $q['offset'] . ', ';
} else {
$pgstrt = absint( ( $page - 1 ) * $q['posts_per_page'] ) . ', ';
}
$limits = 'LIMIT ' . $pgstrt . $q['posts_per_page'];
}
```
What basically happens, once an offset is explicitely set, the `paged` parameter is ignored. The first parameter of the SQL `LIMIT` clause is recalculated from the offset and will be the number of posts to be skipped in the generated SQL query.
From your question, apparently when setting `offset` to `0`, the offset query fails, which is strange, as the following check should return true
```
if ( isset( $q['offset'] ) && is_numeric( $q['offset'] ) )
```
`0`is a valid number and should return true. If this does not on your installation, you should debug the issue
To come back to the issue at hand, we will use the same kind of logic to calculate and set our offset to get post 1 on page 2 and from there paginate the query. For the first page, we will not alter anything, so the posts that is suppose to be on page 1 will still be on page as normal, we would just need to "hide" them later on so that we do not display them on page 1
```
add_action( 'pre_get_posts', function ( $q )
{
if ( !is_admin() // Only target the front end, VERY VERY IMPORTANT
&& $q->is_main_query() // Only target the main query, VERY VERY IMPORTANT
&& $q->is_cateory( 'news' ) // Only target the news category
) {
$current_page = $q->get( 'paged' ); // Get the current page number
// We will only need to run this from page 2 onwards
if ( $current_page != 0 ) { // You can also use if ( is_paged() ) {
// Get the amount of posts per page
$posts_per_page = get_option( 'posts_per_page' );
// Recalculate our offset
$offset = ( ( $current_page - 1) * $posts_per_page ) - $posts_per_page; // This should work on page 2 where it returns 0
// Set our offset
$q->set( 'offset', $offset );
}
}
});
```
You should be seeing the same posts from page 1 on page 2. As I previously stated, if this does not happen, either `is_numeric( 0 )` is returning false (*which it should not*) or you have another `pre_get_posts` action that is also trying to set an offset or you are using making use of the `posts_*` clause filters (*more specifically, the `post_limits` filter*). This would be something you would need to debug by yourself.
The next issue is to correct pagination, beacause as I previously stated, you will be a page short. For this, we will need to add the value of `get_option( 'posts_per_page' )` to the amount of posts found in the query as we are offsetting the query by that amount. by doing this, we are effectively adding `1` to the `$max_num_pages` property.
```
add_action( 'found_posts', function ( $found_posts, $q )
{
if ( !is_admin() // Only target the front end, VERY VERY IMPORTANT
&& $q->is_main_query() // Only target the main query, VERY VERY IMPORTANT
&& $q->is_cateory( 'news' ) // Only target the news category
) {
$found_posts = $found_posts + get_option( 'posts_per_page');
}
}, 10, 2 );
```
This should sort everything, except the first page.
ALL TOGETHER NOW (*and specially for @ialocin - [Yellow Submarine](http://www.youtube.com/watch?v=OkQA9OsJhPQ)*)
----------------------------------------------------------------------------------------------------------------
This should all go into `functions.php`
```
add_action( 'pre_get_posts', function ( $q )
{
if ( !is_admin() // Only target the front end, VERY VERY IMPORTANT
&& $q->is_main_query() // Only target the main query, VERY VERY IMPORTANT
&& $q->is_cateory( 'news' ) // Only target the news category
) {
$current_page = $q->get( 'paged' ); // Get the current page number
// We will only need to run this from page 2 onwards
if ( $current_page != 0 ) { // You can also use if ( is_paged() ) {
// Get the amount of posts per page
$posts_per_page = get_option( 'posts_per_page' );
// Recalculate our offset
$offset = ( ( $current_page - 1) * $posts_per_page ) - $posts_per_page; // This should work on page 2 where it returns 0
// Set our offset
$q->set( 'offset', $offset );
}
}
});
add_filter( 'found_posts', function ( $found_posts, $q )
{
if ( !is_admin() // Only target the front end, VERY VERY IMPORTANT
&& $q->is_main_query() // Only target the main query, VERY VERY IMPORTANT
&& $q->is_cateory( 'news' ) // Only target the news category
) {
$found_posts = $found_posts + get_option( 'posts_per_page');
}
return $found_posts;
}, 10, 2 );
```
FIRST PAGE OPTIONS
------------------
There are a few options here:
**OPTION 1**
I would most probably go for this option. What you would want to do here is to create a `category-news.php` (*if you haven't yet done this*). This will be the template that will be used whenever the `news` category is viewed. This template will be very simply
Example
```
<?php
get_header()
if ( !is_paged() ) { // This is the first page
get_template_part( 'news', 'special' );
} else { // This is not the first page
get_template_part( 'news', 'loop' );
}
get_sidebar();
get_footer();
```
As you can see, I have included two template parts, `news-special.php` and `news-loop.php`. Now, the basics of the two custom templates are:
* `news-special.php` -> This template part will be whatever you would want to display on the first page. Add all your custom static info here. Be very careful not to call the loop in this template as this would display the posts of the first page.
* `news-loop.php` -> This is the template where we will invoke the loop. This section will look something like this:
```
global $wp_query;
while ( have_posts() ) {
the_post();
// Your template tags and markup
}
```
OPTION 2
--------
Create a separate template with your static content and simply use the `category_template` filter to use this template when we view the first page of the `news` category. Also, be sure not to invoke the default loop in this template. Also, make sure that your naming convention here does not collide with template names within the template hierarchy
I hope this is useful. Feel free toleave comments with concerns
EDIT
----
Thanks to the OP, there is a definite bug in the `WP_Query` class, check the [trac ticket #34060](https://core.trac.wordpress.org/ticket/34060). The code I have posted is from Wordpress v4.4, and the bug is fixed in this version.
I went back to the source code of v4.3, where the bug is, and I can confirm that `0` is ignored when set as value to `offset` as the code simply checks whether the `offset` parameter is `empty`. `0` is taken as empty in PHP. I am not sure if this behavior (bug) is only found in v4.3 only or in all previous versions (according to the ticket, this bug is in v4.3), but there is a patch for this bug which you can check out in the trac ticket.

<p>I've created a custom taxonomy register as the code below, but it does not find the taxonomy-specialty.php nor archive.php templates (page not found error).</p>
<p>I did following (as recommended by other threads found on SE and the web):
- re-save the permalinks
- find the taxonomy settings page in wp-admin and when I hover over 'View' it points me to 'mysite.com/events/specialties/footology' for a 'Footology' taxonomy entry I created for a post of type 'event' - so the URL is as expected. However when visiting the link still get page not found error.</p>
<pre><code>$specialty_args = array(

'with_front' => false, // Don't display the category base before "/specialties/"
'hierarchical' => false

I've created a custom taxonomy register as the code below, but it does not find the taxonomy-specialty.php nor archive.php templates (page not found error).
I did following (as recommended by other threads found on SE and the web):
- re-save the permalinks
- find the taxonomy settings page in wp-admin and when I hover over 'View' it points me to 'mysite.com/events/specialties/footology' for a 'Footology' taxonomy entry I created for a post of type 'event' - so the URL is as expected. However when visiting the link still get page not found error.
```
$specialty_args = array(
'hierarchical' => false,
// This array of options controls the labels displayed in the WordPress Admin UI
'labels' => array(
'name' => 'Specialty',
'singular_name' => 'Specialty',
'search_items' => 'Search specialties',
'all_items' => 'All specialties',
'edit_item' => 'Edit specialty',
'update_item' => 'Update specialty',
'add_new_item' => 'Add new specialty',
'new_item_name' => 'New specialty name',
'menu_name' => 'Specialties',
),
'show_ui' => true,
'show_admin_column' => true,
'query_var' => 'specialty',
// Control the slugs used for this taxonomy
'rewrite' => array(
'slug' => 'events/specialties', // This controls the base slug that will display before each term
'with_front' => false, // Don't display the category base before "/specialties/"
'hierarchical' => false
),
);
register_taxonomy('specialty', 'event', $specialty_args);
register_taxonomy_for_object_type('specialty', 'event'); //says in https://codex.wordpress.org/Function_Reference/register_taxonomy under 'Usage' to do this
```
I don't know what is wrong. Help appreciated, thank you!

The page not found error doesn't mean that the template file is not found/used. Note that a URL returns a 404 status header (not found), then 404.php is used (or index.php if 404.php doesn't exist).
I think your real problem is that you have not flushed the rewrite rules after the taxonomy has been registered. To do it, follow these steps:
**Manually**: go to settings->permalinks and click the save button (you don't need to change anything, just click the save button).
**Auto**: in your plugin, use `flush_rewrite_rules()` during plugin activation hook (never use `flush_rewrite_rules()` on every page load). For example:
```
register_activation_hook( __FILE__, 'cyb_plugin_activation' );
function cyb_plugin_activation() {
cyb_register_taxonomy();
flush_rewrite_rules();
}
add_action( 'init', 'cyb_register_taxonomy' );
function cyb_register_taxonomy() {
$specialty_args = array(
'hierarchical' => false,
// This array of options controls the labels displayed in the WordPress Admin UI
'labels' => array(
'name' => 'Specialty',
'singular_name' => 'Specialty',
'search_items' => 'Search specialties',
'all_items' => 'All specialties',
'edit_item' => 'Edit specialty',
'update_item' => 'Update specialty',
'add_new_item' => 'Add new specialty',
'new_item_name' => 'New specialty name',
'menu_name' => 'Specialties',
),
'show_ui' => true,
'show_admin_column' => true,
'query_var' => 'specialty',
// Control the slugs used for this taxonomy
'rewrite' => array(
'slug' => 'events/specialty', // This controls the base slug that will display before each term (renamed to specialty from specialties)
'with_front' => false, // Don't display the category base before "/specialties/"
'hierarchical' => false
),
);
register_taxonomy('specialty', 'event', $specialty_args);
register_taxonomy_for_object_type('specialty', 'event');
}
register_deactivation_hook( __FILE__, 'cyb_plugin_deactivation' );
function cyb_plugin_deactivation() {
// Flush the rewrite rules also on deactivation
flush_rewrite_rules();
}
```

I'm not sure what you exactly need, but normally, by default, `get_terms` returns only terms that actually have posts assigned to them
```
$terms = get_terms( 'exhibition' );
var_dump( $terms );
```
Apart from this, I really do not know what you exactly need

The codex suggests using the function `get_stylesheet_directory()` in this instance as the `get_template_directory_uri()` can get overriden by child themes.
* [get\_template\_directory\_uri()](https://codex.wordpress.org/Function_Reference/get_stylesheet_directory_uri)
* [get\_stylesheet\_directory()](https://codex.wordpress.org/Function_Reference/get_stylesheet_directory)
In my experience WordPress can sometimes provide 2 or 3 similar functions.

I did the same thing a different way and now it's stacked like I want with a div wrapping the content.
This stacks the single product woocommerce output to be as follows:
1. Title
2. Price
3. Add to cart / attributes
4. Excerpt
5. Meta
6. Images
7. Price
8. Add to cart / attributes
9. Tabs
10. Upsell
11. Related
So now on large viewports we float the .product div.images to the left, float the .product div.summary to the right, clear the stuff after it. Hide the .footer-cart-section on large viewports and now the person on a mobile phone won't have to scroll the the entire height of the image to add to cart - if they wish.
In functions.php
```
if ( in_array( 'woocommerce/woocommerce.php', apply_filters( 'active_plugins', get_option( 'active_plugins' ) ) ) ) {
// ==== wrap in div
function output_opening_div() {
echo '<div class="footer-cart-section">';
}
function ouput_closing_div() {
echo '</div><!-- /.footer-cart-section -->';
}
// ==== put the excerpt below the add to cart and before the meta
remove_action('woocommerce_single_product_summary', 'woocommerce_template_single_excerpt',20);
add_action('woocommerce_single_product_summary', 'woocommerce_template_single_excerpt',35);
// ==== move images (with the thumbs) below the content
remove_action( 'woocommerce_before_single_product_summary', 'woocommerce_show_product_images', 20 );
add_action( 'woocommerce_after_single_product_summary', 'woocommerce_show_product_images', 50);
// ==== move all the content after images
remove_action( 'woocommerce_after_single_product_summary', 'woocommerce_output_product_data_tabs', 10 );
remove_action( 'woocommerce_after_single_product_summary', 'woocommerce_upsell_display', 15 );
remove_action( 'woocommerce_after_single_product_summary', 'woocommerce_output_related_products', 20 );

When adding arrays to post meta, using add\_post\_meta, new sub-arrays are added. I was wondering if there was a way to have those sub-arrays named.
so instead of ending up with
```
array([0](2,3), [1](4,5))
```
I would get
```
array ([meaningful_name](2,3),[meaningful_name2](4,5))
```
|
When multiple meta values are used for same meta key, WordPress store the values in different database rows. So every array, is stored in one row.
Initial Data
------------
Let's assume you have an array like this:
```
$family = [
'father' => [ 'John', 'Doe', 40 ],
'mother' => [ 'Jane', 'White', 39 ],
'child_1' => [ 'Luke', 'Doe', 5 ]
];
```
If you store each sub array as a different meta row, the only identifier for that row is the `meta_id` but it's not really meaningful and is hard to get using WordPress functions.
The *"map"* approach
====================
A workaround could be to store a map of values / meta IDs in another post meta.
That can be done thanks to the fact that both `update_post_meta()` and `add_post_meta()` return the meta ID just added.
### Store Data
So you can do something like this:
```
$map = [];
foreach( $family as $who => $person ) {
// update_post_meta returns the meta ID
$map[ $who ] = update_post_meta( $postId, 'family_member', $person );
}
// we store the map of family "role" to meta IDs in a separate meta
update_post_meta( $postId, 'family_members_map', $map );
```
### Retrieve Data
When you retrieve values, e.g.
```
$family = get_post_meta( $postId, 'family_member' );
```
you get a 2 dimensions unkeyed array like this:
```
[
[ 'John', 'Doe', 40 ],
[ 'Jane', 'White', 39 ],
[ 'Luke', 'Doe', 5 ],
]
```
In short you loose the sub array keys.
But you can use the map you stored and the function [`get_post_meta_by_id`](https://developer.wordpress.org/reference/functions/get_post_meta_by_id/) to recreate your original data:
```
$map = get_post_meta( $postId, 'family_members_map', true );
$family = array_combine( array_keys( $map ), array_map( 'get_post_meta_by_id', $map ) );
```
And family will be equal to the original data:
```
[
'father' => [ 'John Doe', 40 ],
'mother' => [ 'Jane White', 39 ],
'child_1' => [ 'Luke Doe', 5 ]
]
```
### Update Data
Update data, it's not very hard:
```
$justBorn = [ 'Anna', 'Doe', 0 ];
// current map
$map = get_post_meta( $postId, 'family_members_map', true);
// add both new sub array and new meta ID to map
$map['child_2'] = update_post_meta( $postId, 'family_member', $justBorn );
// update the map
update_post_meta( $postId, 'family_members_map', $map );
```
An alternative: the *"all in one place"* approach
=================================================
The approach above works, but it's not the easiest way.
In fact, would be easier to store the whole initial associative array (the `$family` array)
is a single meta instead of in different sub-arrays.
```
// store data
update_post_meta( $postId, 'family_members', $family );
// retrieve data (please note the `true` as 3rd argument)
$family = get_post_meta( $postId, 'family_members', true );
// update data
$family = get_post_meta( $postId, 'family_members', true );
$family['child_2'] = [ 'Anna', 'Doe', 0 ];
update_post_meta( $postId, 'family_members', $family );
```
To store, retrieve and update data is quite easy and there's no additional overhead.
Advantages of the *"map"* approach
==================================
In most of the cases, the *"all in one place"* approach is the most convenient.
But if there are hundreds or even thousands of sub arrays, using an unique meta value to store them all would result in a very large amount of memory used to fetch and parse data.
Using different rows and a modern PHP feature like [generators](http://php.net/manual/en/language.generators.overview.php), that amount of memory can be *drastically* reduced.
Moreover, when dealing with *existing* data (maybe inherited from old version of the website), this approach could be helpful to obtain meaningful information without conversion of old data.
Finally, having smaller and more characterized sub arrays stored in different DB rows, a query for posts using meta query and `LIKE` against the serialized array in the meta value *could* be easier and more reliable, even if the actual reliability depends a lot on the structure of the data.

<p>I have a custom query:</p>
<pre><code><?php
query_posts(array(
'post_type' => 'properties',
'meta_key' => 'pd_city',
'orderby' => 'meta_value',
'order' => 'ASC',
'posts_per_page' => 5,
'paged' => get_query_var('paged')
));
?>

I have a custom query:
```
<?php
query_posts(array(
'post_type' => 'properties',
'meta_key' => 'pd_city',
'orderby' => 'meta_value',
'order' => 'ASC',
'posts_per_page' => 5,
'paged' => get_query_var('paged')
));
?>
```
But it doesn't seem to be working. The posts on this page should be listed alphabetically by city (Burnaby, New Westminster, Richmond, Surrey), but they are listed in a random order (I'm not sure how they are being ordered).
Not sure what I'm missing. I created the 'properties' post\_type via the 'Post Meta' Wordpress plugin if that makes a difference.

Attempt using WP\_Query - Also **DOES NOT WORK**
```
<?php

$args = array(
'post_type' => 'properties',
'meta_key' => 'pd_city',
'orderby' => 'meta_value',
'order' => 'ASC',
'posts_per_page' => 5,
'paged' => $paged

$the_query = new WP_Query( $args );
?>
<?php if ($the_query->have_posts()) : while ($the_query->have_posts()) : $the_query->the_post(); ?>
```

Piter is right, don't use `query_posts`.
You could do something like:
```
$paged = ( get_query_var('paged') ) ? get_query_var('paged') : 1;
$args = array(
'post_type' => 'properties',
'meta_key' => 'pd_city',
'orderby' => 'meta_value',
'order' => 'ASC',
'posts_per_page' => 5,
'paged' => $paged
);
$query = new WP_Query( $args );
```
Just make sure you have the values right for your `post_type` and `meta_key` params. I.e, I use an underscore for all my meta keys: `_properties`.
I have a nearly identical query running on a client's project here: <http://centerpoint.com/properties/?pgd=1&v=list&filter=1&list_type=all&sortby=city>

Here is another way of doing it, specially if you need to work with the query object. The issue with merging queries is that you loose the correctness of the query object.
My idea here is to run two separate queries, one very lean one to get post ID's from the `date_query` query and then merging the two arrays of post ID's and then pass those ID's to proper `WP_Query` query.
(*NOTE: This code requires at least PHP 5.4*)
```
$highlights = [8308, 8315];
$args = [
'date_query' => [
[
'after' => '1 week ago'
]
],
'posts_per_page' => 13,
'meta_key' => 'post_views_count',
'orderby' => 'meta_value_num',
'order' => 'DESC',
'cat' => '-907,-908,-909',
'post__not_in' => $highlights,
'fields' => 'ids' // ONLY GET POST ID's, VERY LEAN QUERY
];
$q = get_posts( $args );
$merged_ids = array_merge( $highlights, $q );
```
Note now, the hightlights are in front of the query, and the posts from $q is ordered by date. If you need to retain this order, simply add `'orderby' => 'post__in',` to the arguments of the query below
```
if ( $merged_ids ) {
$args_final = [
'post__in' => $merged_ids,
'posts_per_page' => -1,
'orderby' => 'post__in',
'ignore_sticky_posts' => 1
];
$query_final = new WP_Query( $args_final );
// Run your loop
}
```

I want to sort the result of `get_users()` by last name, first name, user defined fields or whatever.
How can I achieve this while still using `get_users()`?
|
[`get_users()`](https://codex.wordpress.org/Function_Reference/get_users) does not allow you to directly sort by whatever you like, but there are ways around it.
The Codex for `get_users()` says:
>
> **orderby** - Sort by 'ID', 'login', 'nicename', 'email', 'url', 'registered', 'display\_name', 'post\_count', 'include', or 'meta\_value' (query must also contain a 'meta\_key' - see [WP\_User\_Query](https://codex.wordpress.org/Class_Reference/WP_User_Query)).
>
>
>
`meta_value` is a very powerful way to go here. If you choose it, you have to define the `meta_key` which will then define what to order by.
>
> **meta\_key** - The **meta\_key** in the [wp\_usermeta table](https://codex.wordpress.org/Database_Description#Table:_wp_usermeta) for the **meta\_value** to be returned. See [get\_userdata()](https://codex.wordpress.org/Function_Reference/get_userdata#Values_in_users_.26_user_meta_table) for the possible meta keys.
>
>
>
`get_userdata()` can [return quite a lot of values,](https://codex.wordpress.org/Function_Reference/get_userdata#Notes) possibly enough to order by.
---
**Examples**
So, if you want to order by the users last name for example, use `get_users()` like this:
```
$your_users = get_users('orderby=meta_value&meta_key=last_name');
```
Order by first name
```
$your_users = get_users('orderby=meta_value&meta_key=first_name');
```
Order by registration date
```
$your_users = get_users('orderby=meta_value&meta_key=user_registered');
```
You can of course use `order` to reverse the sorting order
```
// Sorting users by registration date - ascending (standard behaviour)
$your_users = get_users('orderby=meta_value&meta_key=user_registered');
// Sorting users by registration date - descending (add order=DESC)
$your_users = get_users('orderby=meta_value&meta_key=user_registered&order=DESC');
```
---
**One step further**
If you want to order by user-defined values, which `get_userdata()` wonΒ΄t deliver, you can pass another parameter to `get_users()`.
```
$your_users = get_users('fields=all_with_meta');
```
This will result in an array which contains all meta data that is linked to a user. You can then use a custom sort function ([via usort()](https://secure.php.net/manual/function.usort.php)) to order by a specific parameter.
```
$your_users = get_users('fields=all_with_meta');
// very basic comparison...
function compare($a, $b) { return ($a->special > $b->special) ? -1 : 1; }
usort($your_users, 'compare');
```

<p>I would like to use something to filter images within an ACF Gallery.

<p>Additionally, how would I echo the category assigned to the image in the div surrounding the image </p>
<p>My loop currently looks like this to output my gallery. </p>

<p>I have a site I'm building in wordpress that has ~80GB of high resolution images, and it's exceeding my managed host's storage space.

<p>Is there a way to hook into that method and modify it to not include the prefix?</p>

It might be a solution to string replace /wp-content/uploads with '' (empty) like for an example:
Lets say: wp\_get\_attachment\_image() returns = '/wp-content/uploads/myimage.png';
```
<?php
echo str_replace('/wp-content/uploads/', '', wp_get_attachment_image());
?>
```
This will result in echo: 'myimage.png'
Try this:
```
function alter_image_src($attr) {
$attr['src'] = str_replace('/wp-content/uploads/', '', $attr['src']);
return $attr;
}
add_filter( 'wp_get_attachment_image_attributes', 'alter_image_src');
```
In your functions page (of theme).

This is basic PHP. Just a note before I continue, never ever globalize variables. Wordpress has already done quite a crappy job regarding this. Globalization is evil, because anyone and anything, knowingly or unknowingly can change a global variable. This makes globals a nightmare to debug. So in short, **NEVER EVER** globalize.
Whenever you need to pass something outside a anonymous function to the function, you should use the `use()` keyword. As example, you can try
```
function () use( $the_query )
{
var_dump( $the_query );
}
```
EDIT:
-----
In your code, you can do the following
```
fluid_grid( function() use ( $the_query )
{
?>
// Here goes the markup that should be printed out later
<?php
} );
```

Is this possible in WordPress?
Like if I use a piece of code to display Post1 image+title and some more code to display six more posts in that category...
But then to do the next category I have to paste the whole code in again and change the category.
Can I just code "repeat, but change variable to \_\_\_ and variable to \_\_\_\_?
Thanks,
JH
```
---
<div class="category-container">
<div class="category-container-category-title" style="background-color:#004377;">
Cat 1
</div>
<div class="category-container-category-post" >
<?php $posts = get_posts( "cat='50'&numberposts=1" ); ?>
<?php if( $posts ) : ?>
<?php foreach( $posts as $post ) : setup_postdata( $post ); ?>
<a href="<?php echo get_permalink($post->ID); ?>" >
<div class="thumbnail-box" style="background-color:#004377;">
<?php if ( has_post_thumbnail()) : the_post_thumbnail('thumb-thumb'); endif; ?>
<h3><?php echo $post->post_title; ?></h3>
</div>
</a>
<?php endforeach; ?>
<?php endif; ?>
</div>
</div>
<div class="category-container-category-posts">
<?php
$args=array(
'cat' => '50',
'offset' => 1,
'showposts'=>6,
'caller_get_posts'=>1
);
$my_query = new WP_Query($args);
$offset = 3;
if( $my_query->have_posts() ) {
while ($my_query->have_posts()) : $my_query->the_post(); ?>
<a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>">
<div>
<h5 style="padding-bottom:25px;"><b>
<?php the_title(); ?></b>
</h5>
</div>
</a>
<?php
endwhile;
} //if ($my_query)
wp_reset_query(); // Restore global post data stomped by the_post().
?>
</div>

This is basic PHP. Just a note before I continue, never ever globalize variables. Wordpress has already done quite a crappy job regarding this. Globalization is evil, because anyone and anything, knowingly or unknowingly can change a global variable. This makes globals a nightmare to debug. So in short, **NEVER EVER** globalize.
Whenever you need to pass something outside a anonymous function to the function, you should use the `use()` keyword. As example, you can try
```
function () use( $the_query )
{
var_dump( $the_query );
}
```
EDIT:
-----
In your code, you can do the following
```
fluid_grid( function() use ( $the_query )
{
?>
// Here goes the markup that should be printed out later
<?php
} );
```

I want to disable the email notification if a user or an admin changes the password of a user.
After some Googling I came to find that I need to create a plugin and overwrite the `wp_password_change_notification` function found in `pluggable.php`.
This is the plugin and function:
```
<?php
/*
Plugin Name: Stop email change password
Description: Whatever
*/
if ( !function_exists( 'wp_password_change_notification' ) ) {
function wp_password_change_notification() {}
}
?>
```
I uploaded the file to my plugin folder and activated it in my admin panel!
This needs to be done with a plugin because the `pluggable.php` file is loaded before the `functions.php` file.
Anyway it doesn't seem to work for me.
The user still receives the email.
I disabled all plugins and run the plugin on a clean install so no interference
The `WP_DEBUG` doesn't show any errors as well!
Can anybody tell me what to change or how to fix it any other way (except core modifications :-))
M.

To disable user email notification, add this in a plugin or theme:
```
add_filter( 'send_password_change_email', '__return_false' );
```
FYI [`wp_password_change_notification()`](https://developer.wordpress.org/reference/functions/wp_password_change_notification/) controls admin email notification when a user changes their password

<p>I'm correctly developing my own theme and so far I got: index, header, footer, functions and style files. The list will go on as I'm progressing with my theme. But I'm considering to use more than one theme at this site with total different files and I'm thinking of using simply different names for files instead the original ones, so instead of header.php it would be blabla.php and so on. With different data inside them, of course.
So... therefor I have very important questions:</p>
<p>Would this method may make any conflict in WP core or something like this? </p>

You probably are over complicating things for yourself. You can use the [template\_include](https://codex.wordpress.org/Plugin_API/Filter_Reference/template_include) filter for that
```
add_filter( 'template_include', 'wpse_206394_template', 99 );
function wpse_206394_template( $template ) {
if ( template should be blabla ) {
$new_template = locate_template( array( str_replace('.php','-blabla.php',$template) ) );
if ( '' != $new_template ) {
return $new_template ;
}
}
return $template;
}
```
but most likely you can get the same effect with proper use of the template hierarchy.

<p>I moved over a development site to the client's hosting server using the WP Clone plugin. It seemed to work just fine, until I noticed a bunch of odd question marks where things like em-dashes and apostrophes should be.</p>
<p>It appears to be a unicode issue, but the only difference I can tell between the two servers is that the client-side is using utf8mb4_unicode_c and my development server is using utf8_unicode_ci.</p>
<p>If I copy and paste a page from the development side to the client side, it displays fine β but I'd rather not have to do that for the entire site (50-plus pages plus a few dozen posts).</p>
<p>I tried exporting the database table from the development site and importing it on the client side, but that led to a bunch of warning messages and everything on the client home page linked back to the development site. </p>
<p>Any ideas on how I can fix this, short of a manual cut-and-paste job?</p>

My args array:
```
$args = array (
'cat' => '1,3,7',
'posts_per_page' => '30'
);
```
How to define `posts_per_page`:
* category 1 : 7 posts,
* category 3 : 10 posts,
* category 7 : 13 posts,

You probably are over complicating things for yourself. You can use the [template\_include](https://codex.wordpress.org/Plugin_API/Filter_Reference/template_include) filter for that
```
add_filter( 'template_include', 'wpse_206394_template', 99 );
function wpse_206394_template( $template ) {
if ( template should be blabla ) {
$new_template = locate_template( array( str_replace('.php','-blabla.php',$template) ) );
if ( '' != $new_template ) {
return $new_template ;
}
}
return $template;
}
```
but most likely you can get the same effect with proper use of the template hierarchy.

<p>Im trying to convert the post title to an image.
i created a php file in the theme folder image.php
with the code
UPDATE: working code</p>
<pre><code>require_once($_SERVER['DOCUMENT_ROOT'] . '/wp-load.php');
$postid = $_GET["postid"];
$string = get_the_title($postid);
$im = imagecreate(100, 30);
$bg = imagecolorallocate($im, 255, 255, 255);
$textcolor = imagecolorallocate($im, 0, 0, 255);
imagestring($im, 5, 0, 0, $string, $textcolor);
header('Content-type: image/png');
imagepng($im);
imagedestroy($im);
</code></pre>
<p>and i call the file with</p>
<pre><code><img src="url/wp-content/themes/v2/image.php?postid=<?php echo $post->ID ?>" />
</code></pre>
<p>ok now to my problem: the image gets created but without the post title.
Do i need to include anything else to get the_title to execute?</p>

In General
----------
The problem here is that you're calling a WordPress function within a PHP file where WordPress isn't loaded.
Including WordPress in your `image.php` file might work if you include the post ID
```
<img src="/wp-content/themes/v2/image.php?post_id=123" />
```
But imagine if you have 100 images on a single page, then you would be running 101 instances of WordPress!
You might try to hook into WordPress and run only minimized version of WordPress, but then we are still running PHP for each of those images.
Another approach would be to avoid any WordPress calls in your `image.php` file and grab only the title text:
```
<img src="/wp-content/themes/v2/image.php?title=Hello+World!" />
```
But here the danger is that anyone could create an image with any kind of text. That's not good. You could add restrictions, like checking the referrer, but that might not be "watertight".
Better approach might be to create the image files when the post title is modified. Then we can simply call the image file with:
```
<img src="/wp-content/uploads/titles/image-123.png" />
```
but with things like browser caching, we might need a cache buster:
```
<img src="/wp-content/uploads/titles/image-123.png?last-modified=1445683693 " />
```
We might also use the post title in the image file name:
```
<img src="/wp-content/uploads/titles/image-hello-world.png" />
```
The only thing here is we would need to generate those images for old posts.
Let's take a closer look at the last mentioned approach.
Implementation
--------------
Let's assume we have the GD image package installed on our server. Then we could extend the `WP_Image_Editor_GD` class to our needs:
```
class WPSE_Image_Editor_GD extends WP_Image_Editor_GD
{
private $wpse_bgclr;
private $wpse_txtclr;
private $wpse_txt;
public function wpse_new( $width = 0, $height = 0 )
{
$this->image = imagecreate( $width, $height );
return $this;
}
protected function wpse_color( $red = 0, $green = 0, $blue = 0 )
{
return imagecolorallocate( $this->image, (int) $red, (int) $green, (int) $blue );
}
public function wpse_textcolor( $red = 0, $green = 0, $blue = 0 )
{
$this->wpse_txtclr = $this->wpse_color( (int) $red, (int) $green, (int) $blue );
return $this;
}
public function wpse_bgcolor( $red = 0, $green = 0, $blue = 0 )
{
$this->wpse_bgclr = $this->wpse_color( (int) $red, (int) $green, (int) $blue );
return $this;
}
public function wpse_text( $text )
{
$this->wpse_txt = imagestring( $this->image, 5, 0, 0, $text, $this->wpse_txtclr );
return $this;
}
}
```
Here we prefix our methods with `wpse_` to avoid possible name collisions in the future.
It's also handy to return `$this` for *chaining*.
We can get the current upload path with:
```
$upload_dir = wp_upload_dir();
```
and to set the upload path for the generated title *.png* files, we could use:
```
$file = sprintf( '%s/wpse_titles/image-%s.png',
$upload_dir['basedir'],
strtolower( sanitize_file_name( $post->post_title ) )
);
```
This would save the *Hello World* title to the file:
```
/wp-content/uploads/wpse_titles/image-hello-world.png
```
We could use the `save_post_{$post_type}` hook to target a specific post type updates.
But don't want to generate it on each update, so let's check if it's a file that already exists with:
```
if( is_file( $file ) )
return;
```
Now we can use our custom class and create an instance:
```
$o = new WPSE_Image_Editor_GD;
```
and create an empty image object, color it, add the post title string to it and then save it:
```
$result = $o
->wpse_new( 300, 60 ) // Width x height = 300 x 60
->wpse_bgcolor( 0, 0, 255 ) // Background color as Blue
->wpse_textcolor( 255, 255, 0 ) // Text color as Yellow
->wpse_text( $post->post_title ) // Hello World
->save( $file, 'image/png' ); // Save it to image-helloworld.png
```
Output Example
--------------
Here's an example how the *image-helloworld.png* image would look like:
[](https://i.stack.imgur.com/g337M.png)
Demo plugin
-----------
Here we add it all together in a demo plugin:
```
<?php
/**
* Plugin Name: WPSE Title Images
* Description: On post update, create a png file of the post title (/uploads/wpse-titles/)
* Plugin Author: Birgir Erlendsson (birgire)
* Plurin URI: http://wordpress.stackexchange.com/a/206433/26350
* Version: 0.0.2
*/
add_action( 'save_post_post', function( $post_id, $post )
{
// Ignore auto save or revisions
if ( wp_is_post_revision( $post_id ) || wp_is_post_autosave( $post_id ) )
return;
if( class_exists( 'WPSE_Image_Editor_GD' ) )
return;
// Get the current upload path
$upload_dir = wp_upload_dir();
// Generated file path
$file = sprintf(
'%s/wpse_titles/image-%s.png',
$upload_dir['basedir'],
sanitize_key( $post->post_title )
);
// Only create it once
if( is_file( $file ) )
return;
// Load the WP_Image_Editor and WP_Image_Editor_GD classes
require_once ABSPATH . WPINC . '/class-wp-image-editor.php';
require_once ABSPATH . WPINC . '/class-wp-image-editor-gd.php';
// Our custom extension
class WPSE_Image_Editor_GD extends WP_Image_Editor_GD
{
private $wpse_bgclr;
private $wpse_txtclr;
private $wpse_txt;
public function wpse_new( $width = 0, $height = 0 )
{
$this->image = imagecreate( $width, $height );
return $this;
}
protected function wpse_color( $red = 0, $green = 0, $blue = 0 )
{
return imagecolorallocate( $this->image, (int) $red, (int) $green, (int) $blue );
}
public function wpse_textcolor( $red = 0, $green = 0, $blue = 0 )
{
$this->wpse_txtclr = $this->wpse_color( (int) $red, (int) $green, (int) $blue );
return $this;
}
public function wpse_bgcolor( $red = 0, $green = 0, $blue = 0 )
{
$this->wpse_bgclr = $this->wpse_color( (int) $red, (int) $green, (int) $blue );
return $this;
}
public function wpse_text( $text )
{
$this->wpse_txt = imagestring( $this->image, 5, 0, 0, $text, $this->wpse_txtclr );
return $this;
}
} // end class
// Generate and save the title as a .png file
$o = new WPSE_Image_Editor_GD;
$result = $o
->wpse_new( 300, 60 ) // Width x height = 300 x 60
->wpse_bgcolor( 0, 0, 255 ) // Background color as Blue
->wpse_textcolor( 255, 255, 0 ) // Text color as Yellow
->wpse_text( $post->post_title ) // Hello World
->save( $file, 'image/png' ); // Save it to image-helloworld.png
}, 10, 3 );
```
We might then create our own template tag, to display the image for each post:
```
if( function_exists( 'wpse_title_image' ) )
wpse_title_image( $default_url = '' );
```
Here's an example, but in a proper plugin structure, we should be able to remove the duplicated code presented here:
```
/**
* Get the current post's title image
*
* @param string $default_url Default image url
* @return string $html Html for the title image
*/
function get_wpse_title_image( $default_url = '' )
{
$post = get_post();
$upload_dir = wp_upload_dir();
$dirname = 'wpse_titles';
$file = sprintf(
'image-%s.png',
strtolower( sanitize_file_name( $post->post_title ) )
);
$file_path = sprintf(
'%s/%s/%s',
$upload_dir['basedir'],
$dirname,
$file
);
$file_url = sprintf(
'%s/%s/%s',
$upload_dir['baseurl'],
$dirname,
$file
);
if( is_file( $file_path ) && is_readable( $file_path ) )
$url = $file_url;
else
$url = $default_url;
return sprintf(
'<img src="%s" alt="%s">',
esc_url( $url ),
esc_attr( $post->post_title )
);
}
```
Then you can define the following wrapper:
```
/**
* Display the current post's title image
*
* @uses get_wpse_title_image()
*
* @param string $default_url Default image url
* @return void
*/
function wpse_title_image( $default_url = '' )
{
echo get_wpse_title_image( $default_url );
}
```
Notes
-----
This demo could be extended further, like:
* take this into a proper plugin structure
* adjusting the handling of the *width* and *height* of each title image.
* auto generate images for all posts
* do this for other post types
* ... etc ...

<p>I am changing hosting + domain name for my WordPress site. For example now if its hosted on 201.0.0.1/mysite and now I want to upload it to mysite.com. This is what I did</p>
<p>exported database from my cpanel
got all files from server using filezilla (public_html folder that has Wordpress root folder as well)
set permalinks option to default and exported all content from existing site.
now planning to create a new database, setup wp-config.php and replace all files in public_html files.
My question is after doing all this will I face any issues regarding page / posts or any other links means it may not happen that I may get some broken links after doing all this. Is there any extra step required with all this mentioned above or is it okay?</p>

I am changing hosting + domain name for my WordPress site. For example now if its hosted on 201.0.0.1/mysite and now I want to upload it to mysite.com. This is what I did
exported database from my cpanel
got all files from server using filezilla (public\_html folder that has Wordpress root folder as well)
set permalinks option to default and exported all content from existing site.
now planning to create a new database, setup wp-config.php and replace all files in public\_html files.
My question is after doing all this will I face any issues regarding page / posts or any other links means it may not happen that I may get some broken links after doing all this. Is there any extra step required with all this mentioned above or is it okay?

In General
----------
The problem here is that you're calling a WordPress function within a PHP file where WordPress isn't loaded.
Including WordPress in your `image.php` file might work if you include the post ID
```
<img src="/wp-content/themes/v2/image.php?post_id=123" />
```
But imagine if you have 100 images on a single page, then you would be running 101 instances of WordPress!
You might try to hook into WordPress and run only minimized version of WordPress, but then we are still running PHP for each of those images.
Another approach would be to avoid any WordPress calls in your `image.php` file and grab only the title text:
```
<img src="/wp-content/themes/v2/image.php?title=Hello+World!" />
```
But here the danger is that anyone could create an image with any kind of text. That's not good. You could add restrictions, like checking the referrer, but that might not be "watertight".
Better approach might be to create the image files when the post title is modified. Then we can simply call the image file with:
```
<img src="/wp-content/uploads/titles/image-123.png" />
```
but with things like browser caching, we might need a cache buster:
```
<img src="/wp-content/uploads/titles/image-123.png?last-modified=1445683693 " />
```
We might also use the post title in the image file name:
```
<img src="/wp-content/uploads/titles/image-hello-world.png" />
```
The only thing here is we would need to generate those images for old posts.
Let's take a closer look at the last mentioned approach.
Implementation
--------------
Let's assume we have the GD image package installed on our server. Then we could extend the `WP_Image_Editor_GD` class to our needs:
```
class WPSE_Image_Editor_GD extends WP_Image_Editor_GD
{
private $wpse_bgclr;
private $wpse_txtclr;
private $wpse_txt;
public function wpse_new( $width = 0, $height = 0 )
{
$this->image = imagecreate( $width, $height );
return $this;
}
protected function wpse_color( $red = 0, $green = 0, $blue = 0 )
{
return imagecolorallocate( $this->image, (int) $red, (int) $green, (int) $blue );
}
public function wpse_textcolor( $red = 0, $green = 0, $blue = 0 )
{
$this->wpse_txtclr = $this->wpse_color( (int) $red, (int) $green, (int) $blue );
return $this;
}
public function wpse_bgcolor( $red = 0, $green = 0, $blue = 0 )
{
$this->wpse_bgclr = $this->wpse_color( (int) $red, (int) $green, (int) $blue );
return $this;
}
public function wpse_text( $text )
{
$this->wpse_txt = imagestring( $this->image, 5, 0, 0, $text, $this->wpse_txtclr );
return $this;
}
}
```
Here we prefix our methods with `wpse_` to avoid possible name collisions in the future.
It's also handy to return `$this` for *chaining*.
We can get the current upload path with:
```
$upload_dir = wp_upload_dir();
```
and to set the upload path for the generated title *.png* files, we could use:
```
$file = sprintf( '%s/wpse_titles/image-%s.png',
$upload_dir['basedir'],
strtolower( sanitize_file_name( $post->post_title ) )
);
```
This would save the *Hello World* title to the file:
```
/wp-content/uploads/wpse_titles/image-hello-world.png
```
We could use the `save_post_{$post_type}` hook to target a specific post type updates.
But don't want to generate it on each update, so let's check if it's a file that already exists with:
```
if( is_file( $file ) )
return;
```
Now we can use our custom class and create an instance:
```
$o = new WPSE_Image_Editor_GD;
```
and create an empty image object, color it, add the post title string to it and then save it:
```
$result = $o
->wpse_new( 300, 60 ) // Width x height = 300 x 60
->wpse_bgcolor( 0, 0, 255 ) // Background color as Blue
->wpse_textcolor( 255, 255, 0 ) // Text color as Yellow
->wpse_text( $post->post_title ) // Hello World
->save( $file, 'image/png' ); // Save it to image-helloworld.png
```
Output Example
--------------
Here's an example how the *image-helloworld.png* image would look like:
[](https://i.stack.imgur.com/g337M.png)
Demo plugin
-----------
Here we add it all together in a demo plugin:
```
<?php
/**
* Plugin Name: WPSE Title Images
* Description: On post update, create a png file of the post title (/uploads/wpse-titles/)
* Plugin Author: Birgir Erlendsson (birgire)
* Plurin URI: http://wordpress.stackexchange.com/a/206433/26350
* Version: 0.0.2
*/
add_action( 'save_post_post', function( $post_id, $post )
{
// Ignore auto save or revisions
if ( wp_is_post_revision( $post_id ) || wp_is_post_autosave( $post_id ) )
return;
if( class_exists( 'WPSE_Image_Editor_GD' ) )
return;
// Get the current upload path
$upload_dir = wp_upload_dir();
// Generated file path
$file = sprintf(
'%s/wpse_titles/image-%s.png',
$upload_dir['basedir'],
sanitize_key( $post->post_title )
);
// Only create it once
if( is_file( $file ) )
return;
// Load the WP_Image_Editor and WP_Image_Editor_GD classes
require_once ABSPATH . WPINC . '/class-wp-image-editor.php';
require_once ABSPATH . WPINC . '/class-wp-image-editor-gd.php';
// Our custom extension
class WPSE_Image_Editor_GD extends WP_Image_Editor_GD
{
private $wpse_bgclr;
private $wpse_txtclr;
private $wpse_txt;
public function wpse_new( $width = 0, $height = 0 )
{
$this->image = imagecreate( $width, $height );
return $this;
}
protected function wpse_color( $red = 0, $green = 0, $blue = 0 )
{
return imagecolorallocate( $this->image, (int) $red, (int) $green, (int) $blue );
}
public function wpse_textcolor( $red = 0, $green = 0, $blue = 0 )
{
$this->wpse_txtclr = $this->wpse_color( (int) $red, (int) $green, (int) $blue );
return $this;
}
public function wpse_bgcolor( $red = 0, $green = 0, $blue = 0 )
{
$this->wpse_bgclr = $this->wpse_color( (int) $red, (int) $green, (int) $blue );
return $this;
}
public function wpse_text( $text )
{
$this->wpse_txt = imagestring( $this->image, 5, 0, 0, $text, $this->wpse_txtclr );
return $this;
}
} // end class
// Generate and save the title as a .png file
$o = new WPSE_Image_Editor_GD;
$result = $o
->wpse_new( 300, 60 ) // Width x height = 300 x 60
->wpse_bgcolor( 0, 0, 255 ) // Background color as Blue
->wpse_textcolor( 255, 255, 0 ) // Text color as Yellow
->wpse_text( $post->post_title ) // Hello World
->save( $file, 'image/png' ); // Save it to image-helloworld.png
}, 10, 3 );
```
We might then create our own template tag, to display the image for each post:
```
if( function_exists( 'wpse_title_image' ) )
wpse_title_image( $default_url = '' );
```
Here's an example, but in a proper plugin structure, we should be able to remove the duplicated code presented here:
```
/**
* Get the current post's title image
*
* @param string $default_url Default image url
* @return string $html Html for the title image
*/
function get_wpse_title_image( $default_url = '' )
{
$post = get_post();
$upload_dir = wp_upload_dir();
$dirname = 'wpse_titles';
$file = sprintf(
'image-%s.png',
strtolower( sanitize_file_name( $post->post_title ) )
);
$file_path = sprintf(
'%s/%s/%s',
$upload_dir['basedir'],
$dirname,
$file
);
$file_url = sprintf(
'%s/%s/%s',
$upload_dir['baseurl'],
$dirname,
$file
);
if( is_file( $file_path ) && is_readable( $file_path ) )
$url = $file_url;
else
$url = $default_url;
return sprintf(
'<img src="%s" alt="%s">',
esc_url( $url ),
esc_attr( $post->post_title )
);
}
```
Then you can define the following wrapper:
```
/**
* Display the current post's title image
*
* @uses get_wpse_title_image()
*
* @param string $default_url Default image url
* @return void
*/
function wpse_title_image( $default_url = '' )
{
echo get_wpse_title_image( $default_url );
}
```
Notes
-----
This demo could be extended further, like:
* take this into a proper plugin structure
* adjusting the handling of the *width* and *height* of each title image.
* auto generate images for all posts
* do this for other post types
* ... etc ...

Below is the code I have. It creates a new user, but it isn't the notification email. I've checked that wp-mail() and php mail() are working correctly.
I'm not sure that this is the right direction. I feel there might be an easier way to do it. If this is the right direction, any pointers on why the notification is not being sent?
Thanks.
```
<?php
define( 'SHORTINIT', true );
require_once( '/var/www/html/mysite/wp-load.php' );
require_once ('/var/www/html/mysite/wp-includes/user.php');
require_once ('/var/www/html/mysite/wp-includes/formatting.php');
require_once ('/var/www/html/mysite/wp-includes/capabilities.php');

require_once ('/var/www/html/mysite/wp-includes/kses.php');
require_once ('/var/www/html/mysite/wp-includes/meta.php');
function __() {}
wp_create_user ( 'testuser8', 'apsswd', '[email protected]' );
wp_new_user_notification ( testuser8,null,'both' );
?>
```

You should [read the codex page re wp\_create\_user](https://codex.wordpress.org/Function_Reference/wp_create_user).
You don't describe the context in which your code runs.
You shouldn't need all those `require_once` calls.
Anyhow, in this line `wp_new_user_notification ( testuser8,null,'both' );` what is `testuser8` ? It's not a variable, it's not a string, it's just some text that probably throws an error.
Try:
```
$user_id = wp_create_user ( 'testuser8', 'apsswd', '[email protected]' );
if( is_wp_error( $user_id ) )
var_dump( $user_id );
else
wp_new_user_notification ( $user_id, null,'both' );
```

You are setting your `$description` to an empty string for any menu item except the top one:
```
if($depth != 0)
{
$description = $append = $prepend = "";
}
```
Thus, you get no output.

Here is a the code snippet:
```
add_action( 'admin_menu', 'travel_site' );
function travel_site(){
add_menu_page( 'Travel Site Menu', 'Travel Site', 'manage_options', 'travel-site-menu', 'ts_admin_main_page' );
add_submenu_page("travel-site-menu","View Travel Requests","View Travel Requests","manage_options","ts-view-travel-requests","ts_admin_vtr_page");

function ts_admin_main_page(){

echo '<p>Testing main travel site menu page</p>';
echo '</div>';
}
function ts_admin_vtr_page(){
echo '<div class="wrap">';
echo '<p>Testing view travel requests</p>';
echo '</div>';
}
```
The problem is when adding the sub menu, the name of the top level menu("Travel Site") creates itself as a sub-level menu. See image: [](https://i.stack.imgur.com/BZako.png)
Basically I don't want "Travel Site" sub-menu under the main menu "Travel Site", how do i remove the submenu "Travel Site"?

Effectively you can do this by adding a sublevel item with the same menu slug as the top level, while changing the submenu item title. This avoids the look of duplicate menu items, even though the destination of the top level, and the first sub menu item are the same.
You have to have at least two sub menu items, and one will be a duplicate destination as your top level menu item.
For example:
```
add_action( 'admin_menu', 'add_travel_menu' );
function add_travel_menu() {
add_menu_page('Travel Site Menu', 'Travel Site', 'manage_options', 'travel-site-menu', 'ts_admin_main_page');
add_submenu_page('travel-site-menu', 'Travel Site', 'View Travel Site', 'manage_options', 'travel-site-menu', 'ts_admin_main_page');
add_submenu_page('travel-site-menu', 'View Travel Requests', 'View Travel Requests', 'manage_options', 'ts-view-travel-requests', 'ts_admin_main_page');
}
function ts_admin_main_page() {
if ( !current_user_can( 'manage_options' ) ) {
wp_die( __( 'You do not have sufficient permissions to access this page.' ) );
}
echo '<div class="wrap">';
echo '<p>Here is where the form would go if I actually had options.</p>';
echo '</div>';
}
```
This would create the Following Menu:
* Travel Site -> travel-site-menu
+ View Travel Site -> travel-site-menu
+ View Travel Requests -> ts-view-travel-requests
[](https://i.stack.imgur.com/I33zc.jpg)
The function ts\_admin\_main\_page actually creates the page that will be the destination for "Travel Site" and "View Travel Site". You would need to create the the similar function "ts\_admin\_vtr\_page" that will create the sub page destination for "View Travel Requests".

I'm working on a contact form for a website using an jQuery Ajax call method that then uses WordPress's building in admin-ajax.php to submit the form's values, send them to an email address via wp\_mail and then, if successful, send back an array through json\_encode. The form works and the email sends but the success data isn't send after and the Ajax :success function doesn't initiate.
This has worked on other sites and I'm not sure why it's not working on this site. It send the email, just my jQuery method gets no success callback.
Here's what I've been using.
jQuery
```
(document).ready(function($){
$.validator.addMethod("lettersonly", function(value, element) {
return this.optional(element) || /^[a-z\s]+$/i.test(value);
}, "Only alphabetical characters");
$.validator.addMethod("phoneNum", function(value, element) {
return this.optional(element) || /^[0-9\-\s]+$/i.test(value);
}, "Phone number can only be number and dashes.");
$("#contact-form").validate({
rules: {
name: {
required:true,
lettersonly: true
},
email: {
required: true,
email: true
},
phone: {
phoneNum: true,
},
message: {
required:true
}
},
messages: {
name: {
required: "Please enter your name.",
lettersonly: "Needs to be letters, no numbers please."
},
email: {
required: "Please enter your email adress.",
email: "Please enter your valid email adress."
},
phone: {
},
message:{
required: "Please enter a message.",
}
},
submitHandler: function(form) {
$('#contact-msg').html('<p class="ajaxLoader">Sending Email...</p>');
$.ajax ({
type: 'POST',
url: ajax_object.ajax_url,
data: $('#contact-form').serialize(),
dataType: 'json',
success: function(response) {
if (response.status == 'success') {
$('#contact-form')[0].reset();
}
$('#contact-msg').html(response.errmessage);
}
});
}
});
});
```
Function.php
```
// CONTACT FORM SCRIPTS
function contactform_add_script() {
wp_enqueue_script( 'contactform-script', get_template_directory_uri().'/assets/js/contact_me.js', array('jquery') , null, true);
wp_localize_script( 'contactform-script', 'ajax_object', array( 'ajax_url' => admin_url( 'admin-ajax.php' ) ) );
}
add_action('wp_enqueue_scripts', 'contactform_add_script');
// CONTACT FORM PROCESSING
function ajax_contactform_action_callback() {
$error = '';
$status = 'error';
if (empty($_POST['name']) || empty($_POST['email']) || empty($_POST['message'])) {
$error = 'All fields are required to enter.';
} else {
$name = filter_var($_POST['name'], FILTER_SANITIZE_STRING, FILTER_FLAG_STRIP_LOW);
$email = filter_var($_POST['email'], FILTER_SANITIZE_EMAIL);
$number = filter_var($_POST['phone'], FILTER_SANITIZE_NUMBER_INT);
// $treatments = filter_var($_POST['treatments'], FILTER_SANITIZE_STRING, FILTER_FLAG_STRIP_LOW);
$subject = 'A message from St. Romain Interiors\'s contact form.';
$message .= PHP_EOL.'Sender\'s name: '.$name;
$message .= PHP_EOL.'Phone number: '.$number;
$message .= PHP_EOL.'E-mail address: '.$email;
$message .= PHP_EOL.'Message: '.stripslashes($_POST['message']);
$sendmsg = "Thanks for the message! We will respond as soon as possible.";
$to = '[email protected]'; // If you like change this email address
// replace "[email protected]" with your real email address
$header .= 'Reply-To: '.$email.PHP_EOL;
if ( wp_mail($to, $subject, $message, $header) ) {
$status = 'success';
$error = $sendmsg;
} else {
$error = 'Some errors occurred.';
}
}
$resp = array('status' => $status, 'errmessage' => $error);
header( "Content-Type: application/json" );
echo json_encode($resp);
die();
}
add_action( 'wp_ajax_contactform_action', 'ajax_contactform_action_callback' );
add_action( 'wp_ajax_nopriv_contactform_action', 'ajax_contactform_action_callback' );
```
UPDATE!
If I replace the submitHandler with this it returns the sentence, but now the email is never sent...
```
submitHandler: function(form) {
$('#contact-msg').html('<p class="ajaxLoader">Sending Email...</p>');
$.ajax ({
type: 'POST',
url: ajax_object.ajax_url,
data: { action: "contactform_action",
values: $('#contact-form').serialize() },
dataType: 'json',
success: function(response) {
$('#contact-msg').html('<p>Thanks for the message!</p>');
}
});
}
```
UPDATE #2
I replaced the success function with the original from the first post, but kept the data values you suggested and it's doing the same old thing, sending the email but not sending a success callback. On Mozilla Firebug I was able to find this information in the Response Headers panel.

Effectively you can do this by adding a sublevel item with the same menu slug as the top level, while changing the submenu item title. This avoids the look of duplicate menu items, even though the destination of the top level, and the first sub menu item are the same.
You have to have at least two sub menu items, and one will be a duplicate destination as your top level menu item.
For example:
```
add_action( 'admin_menu', 'add_travel_menu' );
function add_travel_menu() {
add_menu_page('Travel Site Menu', 'Travel Site', 'manage_options', 'travel-site-menu', 'ts_admin_main_page');
add_submenu_page('travel-site-menu', 'Travel Site', 'View Travel Site', 'manage_options', 'travel-site-menu', 'ts_admin_main_page');
add_submenu_page('travel-site-menu', 'View Travel Requests', 'View Travel Requests', 'manage_options', 'ts-view-travel-requests', 'ts_admin_main_page');
}
function ts_admin_main_page() {
if ( !current_user_can( 'manage_options' ) ) {
wp_die( __( 'You do not have sufficient permissions to access this page.' ) );
}
echo '<div class="wrap">';
echo '<p>Here is where the form would go if I actually had options.</p>';
echo '</div>';
}
```
This would create the Following Menu:
* Travel Site -> travel-site-menu
+ View Travel Site -> travel-site-menu
+ View Travel Requests -> ts-view-travel-requests
[](https://i.stack.imgur.com/I33zc.jpg)
The function ts\_admin\_main\_page actually creates the page that will be the destination for "Travel Site" and "View Travel Site". You would need to create the the similar function "ts\_admin\_vtr\_page" that will create the sub page destination for "View Travel Requests".

<p>Is there a standard way to get all the registered sizes of the featured images?
One can register different sizes with <code>add_image_size()</code>.
What I need, is to get all the sizes of a featured image of a post.
Something like this:</p>
<p>$sizes = get_post_feature_image_sizes($postid);</p>
<p>...which will return an array of objects like this (here in JSON format):</p>
<pre><code>[
{width: 200, height: 300, url: 'http://.........../wp-content/uploads/2015/10/file-200x300.jpg'},
{width: 300, height: 400, url: 'http://.........../wp-content/uploads/2015/10/file.jpg'},
]
</code></pre>
<p>Is there anything like this, or I will have to scan all the upload folder file names with regex?</p>

I don't remember a function that will do precisely that, but it is easily achieved with API overall:
1. Retrieve attachment ID with [`get_post_thumbnail_id()`](https://developer.wordpress.org/reference/functions/get_post_thumbnail_id/)
2. Retrieve available sizes with [`get_intermediate_image_sizes()`](https://developer.wordpress.org/reference/functions/get_intermediate_image_sizes/)
3. For each size use [`wp_get_attachment_image_src()`](https://developer.wordpress.org/reference/functions/wp_get_attachment_image_src/), which gives precisely data you need (URL and dimensions).

Add lines below to `.htaccess` file after the line, `#End WordPress`:

Is anything else I shoud do?
UPD. After this procedure iI have following:

namespacing a function, in WP land, just means prefixing it with something that makes it more unique and unlikely to conflict with anything else. Generally that means you do both a "vendor" and a "package". For instance, if I'm building a plugin, my function upload mimes function might be...
```
add_filter('upload_mimes', 'chrisguitarguy_pluginname_mimes');
function chrisguitarguy_pluginname_mimes($mimes)
{
// ...
}
```
Where `chrisguitarguy` is my "vendor" name and `pluginname` is the package. You can do this [PHP namespaces](https://wordpress.stackexchange.com/questions/63668/autoloading-namespaces-in-wordpress-plugins-themes-can-it-work) as well.
```
namespace Chrisguitarguy\PluginName;
add_action('upload_mimes', __NAMESPACE__.'\\mimes');
function mimes($mimes)
{
// ...
}
```
>
> Is anything else I shoud do?

Nope, what you have is perfect. You may want to specify that svgz is gzipped in your `.htaccess`.
```
AddType image/svg+xml .svg .svgz
// http://httpd.apache.org/docs/2.2/mod/mod_mime.html#addencoding
AddEncoding gzip svgz
```
Newer versions of apache might include this config by default?

I'm trying to remove current\_page\_parent class from the blog index menu item (I got a custom page to display all blog posts and it is in the menu) when navigating custom post type archive page and custom post type posts.
I've found similar questions but I can't figure out how to solve it. In addition, I don't have the current\_page\_parent when navigating the custom\_post\_type (I guess it is related).

You can use the [`nav_menu_css_class`](https://codex.wordpress.org/Plugin_API/Filter_Reference/nav_menu_css_class) filter to add or remove classes from menu items. Each individual menu item will have this filter applied. An array of classes and the menu item object will be passed to the function, and you will `return` an array of the classes you want the menu item to have.
PHP's [`array_diff`](http://php.net/manual/en/function.array-diff.php) can be used to remove classes, and adding items can be accomplished by appending class names to the array via `$classes[] = 'some-class-name'`. You can use the [`Conditional Tags`](https://codex.wordpress.org/Conditional_Tags) to check what sort of page is currently being viewed to determine what you need to add or remove.
Here's a quick example that checks if the page currently being viewed is either an archive or single post of the type `your-post-type`, and the menu item name is `Blog`. If those conditions are met, the `current_page_parent` class is removed from the array of classes for that menu item. You can add to or tweak this for your needs.
```
function wpdev_nav_classes( $classes, $item ) {
if( ( is_post_type_archive( 'your-post-type' ) || is_singular( 'your-post-type' ) )
&& $item->title == 'Blog' ){
$classes = array_diff( $classes, array( 'current_page_parent' ) );
}
return $classes;
}
add_filter( 'nav_menu_css_class', 'wpdev_nav_classes', 10, 2 );
```

<p>I am learning about shortcodes. I've made 2 shortcodes that makes an accordion with bootstrap. One shortode (accordionGroup) creates the body that contains one or more shortcodes to make the items and it's content (accordionItem).</p>

You could pass the variable via a `global` but it would be neater to trap it in a static variable:
```
function track_acc_id($new_id = false) {
static $id;
if (!empty($new_id)) {
$id = $new_id;
}
return $id;
}
//This is the accordion container
function accordionGroup( $atts, $content = null )
{
extract(shortcode_atts(array(
'id_container' => '',
), $atts));
track_acc_id($id_container);
return "<div class='panel-group' id=".$id_container." role='tablist' aria-multiselectable='true'>".do_shortcode($content)."</div>";
}
add_shortcode( 'accordion-group', 'accordionGroup');
//This is the accordion item. It's need a reference from the accordion ID
function accordionItem( $atts, $content = null)
{
extract(shortcode_atts(array(
'titulo' => '',
'id' => '',
), $atts));
$id = track_acc_id();
return "
<div class='panel panel-default'>
<div class='panel-heading' role='tab' id=".$id.">
<h4 class='panel-title'>
<a class='collapsed' role='button' data-toggle='collapse' data-parent='#the-reference-goes-here' href='#".$id."-collapse' aria-expanded='false' aria-controls=".$id."-collapse'>".$titulo."</a>
</h4>
</div>
<div id='".$id."-collapse' class='panel-collapse collapse' role='tabpanel' aria-labelledby=".$id.">
<div class='panel-body'>".$content."</div>
</div>
</div>";
}
add_shortcode( 'accordion-item', 'accordionItem');
echo do_shortcode('[accordion-group id_container="d00d"]');
echo do_shortcode('[accordion-item]');
```

The localizing functions have two variaties, one that echos the string value and the other one that returns it's string value.
Because you would want to display the string (*`echo` it*), you would want the correct function for the specific string which will echo the output. For easy simple strings (*`__('PLAYER POINTS AT A GLANCE.','gogreensoccer')`*) like you have above, the `__()` and `_e()` functions would work
* `__('PLAYER POINTS AT A GLANCE.','gogreensoccer')` would return the string value, useful if you need add a value to a variable and store for later use
* `_e('PLAYER POINTS AT A GLANCE.','gogreensoccer')` would be what you need. This will echo the string to screen
Both are valid in all plugins and themes

<p>The functions <a href="https://codex.wordpress.org/Function_Reference/get_bloginfo" rel="nofollow">get_bloginfo</a>() and bloginfo() both return information about the blog but accessing it each time seems unnecessary. Is there a function that will return the bloginfo as an object with properties? </p>
<p><strong>More Info:</strong><br>
I have tokens in my markup and I want to replace those tokens with the blog info. Since I'm replacing tokens over multiple posts I don't want to call <code>get_bloginfo("name");</code> multiple times. Instead I want to put it into an object I can reuse for each call. </p>

The functions [get\_bloginfo](https://codex.wordpress.org/Function_Reference/get_bloginfo)() and bloginfo() both return information about the blog but accessing it each time seems unnecessary. Is there a function that will return the bloginfo as an object with properties?
**More Info:**
I have tokens in my markup and I want to replace those tokens with the blog info. Since I'm replacing tokens over multiple posts I don't want to call `get_bloginfo("name");` multiple times. Instead I want to put it into an object I can reuse for each call.
|
Here is my workaround if one does not exist:
```
/**
* Get an object with blog info values
*/
function getBlogInfo() {
$info = new stdClass();
$info->name = get_bloginfo("name");
$info->description = get_bloginfo("description");
$info->wpurl = get_bloginfo("wpurl");
$info->url = get_bloginfo("url");
$info->admin_email = get_bloginfo("admin_email");
$info->charset = get_bloginfo("charset");
$info->version = get_bloginfo("version");
$info->html_type = get_bloginfo("html_type");
$info->text_direction = get_bloginfo("text_direction");
$info->language = get_bloginfo("language");
$info->stylesheet_url = get_bloginfo("stylesheet_url");
$info->stylesheet_directory = get_bloginfo("stylesheet_directory");
$info->template_url = get_bloginfo("template_url");
$info->template_directory = get_bloginfo("template_url");
$info->pingback_url = get_bloginfo("pingback_url");
$info->atom_url = get_bloginfo("atom_url");
$info->rdf_url = get_bloginfo("rdf_url");
$info->rss_url = get_bloginfo("rss_url");
$info->rss2_url = get_bloginfo("rss2_url");
$info->comments_atom_url = get_bloginfo("comments_atom_url");
$info->comments_rss2_url = get_bloginfo("comments_rss2_url");
$info->siteurl = home_url();
$info->home = home_url();
return $info;
}
// the following is pseudo code to give you example of what I'm doing
$info = getBlogInfo();
for ($i=0;i<count(posts);$i++) {
$post = $posts[i];
$value = $post->value.replace("{name}", $info->name);
$value = $post->value.replace("{description}", $info->description);
$postsArray.push($post);
}
```
The reason I chose this as an answer is because I need to access the properties of the object more than once. So once it's created subsequent calls are getting the values not calling the functions repeatedly which may or may not be expensive. I don't know.
Also, the question and answer is not asking "the best" way you can do things it's asking how to do a specific thing and this answer fits that specific thing mentioned in the question. I'm saying all this because people down vote all the time for not doing things the way they were taught or "the best" way.
*Update: I added a use case so you can see how I'm using the function and method. I don't always do this but I think it will explain things.*

<p>I'm a new WordPress developer and recently I've been having problems (on multiple sites) with <code>include_once</code> and <code>require_once</code> for PHP files. If I include <code>(get_theme_directory_uri() . 'subdir/file')</code> the specified file gets included (or required, which leads to fatal errors) but if any WordPress functions are called within 'file' I get something similar to: </p>
<blockquote>
<p>'<strong>Call to undefined function</strong> <code>add_action()</code> in /full/path/to/file'.</p>
</blockquote>
<p>The apparent solution I've found is to do: </p>
<pre><code>include(dirname(__FILE__) . "/subdir/filename");
</code></pre>
<p>Is this right or did I miss 'the WordPress way' to include files somewhere? </p>

I'm a new WordPress developer and recently I've been having problems (on multiple sites) with `include_once` and `require_once` for PHP files. If I include `(get_theme_directory_uri() . 'subdir/file')` the specified file gets included (or required, which leads to fatal errors) but if any WordPress functions are called within 'file' I get something similar to:
>
> '**Call to undefined function** `add_action()` in /full/path/to/file'.
>
>
>
The apparent solution I've found is to do:
```
include(dirname(__FILE__) . "/subdir/filename");
```
Is this right or did I miss 'the WordPress way' to include files somewhere?
|
If you check <https://codex.wordpress.org/Function_Reference/get_template_directory_uri>
You will see `get_template_directory_uri()` returns a uri, not a server path.
You should use instead the `get_template_directory()` function, which returns the path to the theme, without trailing slash:
```
include get_template_directory() . '/subdir/filename.php';
```
For a plugin you can use the `plugin_dir_path()` function:
```
include plugin_dir_path( __FILE__ ) . '/subdir/filename.php';
```

You are using PHP inside a single quote and a malformed one at that. That won't work. Step one is to get that string right:
```
_e( 'The page you are looking for is not here. Why donβt you try the <a href="'.esc_url( home_url( '/' ) ).'">homepage</a>?', 'braveandco' );
```
That is pure PHP. Check PHP's manual for [proper string construction](http://php.net/manual/en/language.types.string.php) and for the [concatenation operators](http://php.net/manual/en/language.operators.string.php).
Now, the [`_e()`](https://codex.wordpress.org/Function_Reference/_e) function is a language translation string. That means it is supposed to be replaceable by translations into other languages. Since you have a dynamic component, that translation could be tricky. In fact, what you are doing now [is exactly what the Codex instructs you not to do.](https://codex.wordpress.org/I18n_for_WordPress_Developers#Placeholders) What you want to do instead is provide a stable string for translation then switch in whatever dynamic components you need.
```
printf(

Of course it doesn't. When you remove `get_header()` you also remove the code that loads the CSS files, not to mention that you remove large blocks of necessary HTML markup. The template you've posted above is very, very broken.
You've also left out `get_footer()` which will most likely leave your markup broken as well.
Instead of leaving out [`get_header()`](https://codex.wordpress.org/Function_Reference/get_header) use it with an optional argument to load a truncated header file for your 404 page:
>
> Description
>
>
> Includes the header.php template file from your current theme's
> directory. If a name is specified then a specialised header
> header-{name}.php will be included.
>
>
> If the theme contains no header.php file then the header from the
> default theme wp-includes/theme-compat/header.php will be included.
>
>
>
For example (from the Codex):
```
if ( is_home() ) :
get_header( 'home' );
elseif ( is_404() ) :
get_header( '404' );
else :
get_header();
endif;
```
In your template, you only need `get_header( '404' );` plus a PHP file named `header-404.php` containing whatever you want to display.

The thing is that, contrary to popular belief, `pre_get_posts` does not work for single Page requests.[1](https://codex.wordpress.org/Plugin_API/Action_Reference/pre_get_posts) Not even for is\_front\_page().
As for `get posts()`, in order to work I needed to use a syntax like:
```
<?php global $post;
$myposts = get_posts();
foreach( $myposts as $post ) : setup_postdata($post); ?>
...
<?php endforeach;
wp_reset_postdata(); ?>
```

<?php get_posts(); while ( have_posts() ) : the_post(); ?>

<p>I have a rather silly situation.</p>
<p>I tried <a href="https://perishablepress.com/quickly-disable-or-enable-all-wordpress-plugins-via-the-database/" rel="nofollow">this query </a></p>
<pre><code>UPDATE wp_options SET option_value = 'a:0:{}' WHERE option_name = 'active_plugins';
</code></pre>
<p>which disabled all my plugins. I was testing some issues on my site and this was the only solution to disable them. I had no wp admin access.</p>
<p>The problem is that after I add the old code back in "active_plugins" and disabled or enabled any (random) plugins, the site crashes and the "active_plugins" entry becomes blank.</p>
<p>At the moment, the only solution that I see is to overwrite the wp_options table. Using a backup for the whole database is not a good solution due to the fact that the site is an active WooCommerce based site with daily orders. </p>
<p><strong>My question:</strong> Is there something important in wp_options that might get lost if I put an older version of it in the database?</p>

I have a rather silly situation.
I tried [this query](https://perishablepress.com/quickly-disable-or-enable-all-wordpress-plugins-via-the-database/)
```
UPDATE wp_options SET option_value = 'a:0:{}' WHERE option_name = 'active_plugins';
```
which disabled all my plugins. I was testing some issues on my site and this was the only solution to disable them. I had no wp admin access.
The problem is that after I add the old code back in "active\_plugins" and disabled or enabled any (random) plugins, the site crashes and the "active\_plugins" entry becomes blank.
At the moment, the only solution that I see is to overwrite the wp\_options table. Using a backup for the whole database is not a good solution due to the fact that the site is an active WooCommerce based site with daily orders.
**My question:** Is there something important in wp\_options that might get lost if I put an older version of it in the database?
|
The `wp_options` table holds a lot of information, whether you deem it important or not really depends on what plugins and information you have set up on your website and how important your website is to you.
For example as you've noticed it can hold the information for your active plugins, if you activate an important plugin and then rollback to a database from a week prior, you'll not have that plugin active and that could cause issues - think security plugins, or user enhancement plugins, they're important to you and your users. Even with 500 rows displayed per page in PHPMyAdmin I have 7 pages of data in `wp_options` I'd say for myself that it's all important for my website - it's security settings for the most part.
The table also holds some crutial information like your site url, home url etc. If you don't have these set up in your `wp-config.php` file then removing them *may* cause you some issues too. Also if you've changed the admin email through `wp_options` and rollback to an older database copy without this change well, it's not the end of the world you can edit it again but if you have plugins that utilise it then they may play up too. It's just unnecessary hassle I think to have to re-edit these things, not a disaster though.
It's better to always back up your database just prior to making changes, that way you can always rollback to a version that's same day to your editing.

<p>I would like to create a page template that will have two containers. Left one should be for text (it is a multilingual website so that is why I need a page template), and the right side should be for images which are the same for all languages.
My question is, what do I have to create so a client can insert and edit images as he pleases?
Do I have to create a post, a page or something else? It must not be indexed as itself. I am interested in "the right Wordpress way"</p>
<pre><code><div class="col-md-6">
<?php the_content(); ?>
</div>
<div class="col-md-6">
<?php // include images ?>

Also I need term slug, how do I can get the slug of the term if I know attribute key/attribute label/term value??
|
This is the output of the function:
```
array(
'pa_size' => array(
'label' => 'Size',
'value' => 'Medium',
)
)
```
You get the slug like this:
```
$terms = WC_Order_Item_Meta::get_formatted();
foreach($terms as $slug => $term){
}
```

*Here's just a demo test for fun, just to see if this might be possible:*
Demo
----
First we set the post's password, the usual way:
[](https://i.stack.imgur.com/1zKPe.jpg)
Then we create a *custom field* called `wpse_extra_passwords` that takes comma seperated passwords:
[](https://i.stack.imgur.com/lyZr6.jpg)
These are the extra passwords for that post.
Let's define the following helper function, based on the `post_password_required()` core function:
```
/**
* Helper function, check password + extra passwords
*/
function wpse_post_password_required( $post = null )
{
$post = get_post($post);
if ( empty( $post->post_password ) )
return false;
if ( ! isset( $_COOKIE['wp-postpass_' . COOKIEHASH] ) )
return true;
require_once ABSPATH . WPINC . '/class-phpass.php';
$hasher = new PasswordHash( 8, true );
$hash = wp_unslash( $_COOKIE[ 'wp-postpass_' . COOKIEHASH ] );
if ( 0 !== strpos( $hash, '$P$B' ) )
return true;
// Check the current password
if( $hasher->CheckPassword( $post->post_password, $hash ) )
return false;
// Fetch extra passwords
if( ! $extra_passwords = get_post_meta( $post->ID, 'wpse_extra_passwords', true ) )
return true;
// Check these extra passwords
$extra = explode( ',', $extra_passwords );
foreach( (array) $extra as $password )
{
$password = trim( $password );
if( ! empty( $password ) && $hasher->CheckPassword( $password, $hash ) )
return false;
}
return true;
}
```
Then we hook into the `the_password_form` filter and target the single post object in the main loop:
```
/**
* Support extra post passwords for single posts in the main loop
*/
add_filter( 'the_password_form', function( $output )
{
if( ! is_single() || ! in_the_loop() || did_action( 'the_password_form' ) )
return $output;
$post = get_post();
// Display password form if none of the passwords matches:
if( wpse_post_password_required( $post ) )
return $output;
// Get the current password
$password = $post->post_password;
// Temporary remove it
$post->post_password = '';
// Fetch the content
$content = get_the_content();
// Set the password back
$post->post_password = $password;
return $content;
} );
```
Hopefully you can test it and play with it further.
Notes
-----
You mentioned passwords like 2314. It's very easy to write a program that can guess simple passwords like that. So I used a little bit stronger passwords in this demo.

<p>I am trying to display Popular Posts on my website, selected by a mixture of Views and Comment Count. Since views are always way more than Comments, I am multiplying the Comment Count by X, but it doesnt seem to work how I was hoping it would. The Query Result is just ordered by the Meta Value "Views". I assume this is because I would need to calculate the Sum of Views + Comment Count * X and then order by it... But I am not sure how to accomplish this with using only get_posts(). Can somebody point me in the correct direction? :)</p>
<p>This is my Code</p>
<pre><code>$home_top_news = get_posts(
array(
'post_type' => array('post','reviews'),
'post_status' => 'publish',
'numberposts' => '15',
'meta_key' => 'views',
'orderby' => array(
'meta_value_num' => 'DESC',
'(comment_count * 10)' => 'DESC',
),
'date_query' => array(
array(
'after' => '12 days ago'

)
)

The question seems a bit vague, there a lot of steps creating an API, but I'll try to resume:
1. Create an interaction page (You can use the wp-ajax or a page template)
2. Code the function which will read parameters and execute the code
3. Output only the result to browser. You can output json with a code line like:
`echo json_encode( $result );`

<p>I am using get_post() to call a single Wordpress post using it's post ID. I have successfully managed to pull the content / title of the post but would like to also pull custom fields also.</p>
<p>The code below is how I declare custom fields in a standard wp_query:</p>
<pre><code>$customField = (get_post_meta($post->ID, "_mcf_customField", true));
</code></pre>
<p>And my get_post code below:</p>
<pre><code> $my_id = 401491;
$post_id = get_post($my_id);
$customField = get_post_meta($post_id, "_mcf_customField", true); // I do not think this is correct
$content = $post_id ->post_content;
echo $content;
echo $customField; // No output
</code></pre>
<p>I believe the customField variable above is declared incorrectly, cannot seem to find anything in the Codex that sheds any light though. Does anyone have experience using Custom fields with get_post?</p>

I am using get\_post() to call a single Wordpress post using it's post ID. I have successfully managed to pull the content / title of the post but would like to also pull custom fields also.
The code below is how I declare custom fields in a standard wp\_query:
```
$customField = (get_post_meta($post->ID, "_mcf_customField", true));
```
And my get\_post code below:
```
$my_id = 401491;
$post_id = get_post($my_id);
$customField = get_post_meta($post_id, "_mcf_customField", true); // I do not think this is correct
$content = $post_id ->post_content;
echo $content;
echo $customField; // No output
```
I believe the customField variable above is declared incorrectly, cannot seem to find anything in the Codex that sheds any light though. Does anyone have experience using Custom fields with get\_post?
|
You already know the ID, so just use it:
```
$customField = get_post_meta($my_id, "_mcf_customField", true);
```
But only for reference, if you want to get the ID from the object:
```
$customField = get_post_meta($post_id->ID, "_mcf_customField", true);
```

<p>The field <code>participantes</code> stores user ids separated by comma, like <code>345,1,34</code>.</p>
<p>This only works when the current user id is the first number in the list.</p>

```
'meta_query' => array(
array(
'key' => 'participantes',
'value' => $user_id,

The field `participantes` stores user ids separated by comma, like `345,1,34`.
This only works when the current user id is the first number in the list.
|
I believe, more robust solution would be to allow multiple values of custom field 'participants'. You can store like following
```
add_post_meta($post_id,'participants','value1');
add_post_meta($post_id,'participants','value2');
add_post_meta($post_id,'participants','value3');
add_post_meta($post_id,'participants','value4');
```
Deletion would be like
```
delete_post_meta($post_id,'participants','value1');
```
Query will then change to a simpler one.
```
'meta_query' => array(
array(
'key' => 'participants',
'value' => $user_id,
'compare' => '=',
),
)
```
In case you would like to go for an array implementation, you can store values as following
```
$array = array('value1','value2','value3');
update_post_meta($post_id,'participants',$array);
```
And search can be done like
```
'meta_query' => array(
array(
'key' => 'participants',
'value' => '"'.$userid.'"',
'compare' => 'LIKE',
),
)
```

<p>I have a function which checks if $_POST is set (a form which submits to the same page). I need to have it initialized before the page is loaded because the function will do a header <strong>redirect</strong> if the validation goes through without errors.</p>
<p>So the function is registered like this:</p>
<pre><code>add_action('init', 'signup_validate_insert');
</code></pre>
<p>And the function itself starts like this:</p>
<pre><code>function signup_validate_insert(){
$errors = false;
if (!empty($_POST['submit_msg'])) {
//validation and stuff
}
</code></pre>
<p>And if there are errors, it returns the errors array:</p>
<pre><code>return $errors;
</code></pre>
<p>When the submit button is pressed, the function registers it as it should, and goes through the validation. I have checked to see that the errors array is being filled in the function. But the variable is not returned! (although I have set "return $errors")</p>
<p>The variable is supposed to be returned to the template, where the errors can be displayed if $errors are not empty.</p>
<p>I have tried switching to <code>add_filter</code> instead, with the same result.</p>
<p>So the question is really how to be able to return this variable - hope you can help!</p>

I have a function which checks if $\_POST is set (a form which submits to the same page). I need to have it initialized before the page is loaded because the function will do a header **redirect** if the validation goes through without errors.
So the function is registered like this:
```
add_action('init', 'signup_validate_insert');
```
And the function itself starts like this:
```
function signup_validate_insert(){
$errors = false;
if (!empty($_POST['submit_msg'])) {
//validation and stuff
}
```
And if there are errors, it returns the errors array:
```
return $errors;
```
When the submit button is pressed, the function registers it as it should, and goes through the validation. I have checked to see that the errors array is being filled in the function. But the variable is not returned! (although I have set "return $errors")
The variable is supposed to be returned to the template, where the errors can be displayed if $errors are not empty.
I have tried switching to `add_filter` instead, with the same result.
So the question is really how to be able to return this variable - hope you can help!

actions do not "return" values. If you need to do some heavy computation that you want to avoid redoing at a later stage then you should store the value at a global variable (pure global, static or a field in an object depending on your favorite coding style).

I tried this code but this uses id :</p>
<pre><code><?php $post = get_post('5653'); //assuming $id has been initialized

I want to load products deatails on my custom page.Is there any way that i can use the `url key` like `http://localhost/mysite/product/samsung-1`.In this url `samsung-1` is the key for that product.I want to use this and get product details like name,description and attributes.Can i do this using `url key` or i have to use id for this.thanks
I tried this code but this uses id :
```
<?php $post = get_post('5653'); //assuming $id has been initialized
echo "<pre/>";
print_r($post);
wp_reset_postdata();?>
```

You simply can use the existing function [`get_page_by_path()`](https://codex.wordpress.org/Function_Reference/get_page_by_path) for this, which has a third parameter `$post_type` you can specify. In your case a post from the custom post type `product` is what you want.
Basic example:
```
$product_obj = get_page_by_path( $slug, OBJECT, 'product' );
```

<p>I am trying to get a list of my Wordpress categories to display on a Page, but haven't cracked this yet. </p>
<p>So far, I have been able to create a <strong>custom category page</strong> (category-categoryname.php), to display a list of Page Titles associated with a single category. The code I have used for this includes the following Loop:</p>
<pre><code>while ( have_posts() ) : the_post(); ?>
<h4><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></h4>
</code></pre>
<p>However, I am now trying to display a list of Category titles on a normal WP Page, using the plugin "Post Snippets" to insert the PHP.</p>
<p><strong>Q1:</strong> How do I change The Loop to display all Category titles, instead of Pages associated with a single category?</p>
<p><strong>Q2:</strong> Is there anything else I need to add, like some code to functions.php etc?</p>
<p><strong>Q3:</strong> Would it be easier to create a custom page template, instead of pasting into a regular page?</p>
<p>Note, I am not trying to filter out any categories from the list, like sub-categories or categories without associated pages/posts etc. Although filtering out 'Uncategorised' would be nice.</p>
<p>Thank you for reading</p>

I am trying to get a list of my Wordpress categories to display on a Page, but haven't cracked this yet.
So far, I have been able to create a **custom category page** (category-categoryname.php), to display a list of Page Titles associated with a single category. The code I have used for this includes the following Loop:
```
while ( have_posts() ) : the_post(); ?>
<h4><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></h4>
```
However, I am now trying to display a list of Category titles on a normal WP Page, using the plugin "Post Snippets" to insert the PHP.
**Q1:** How do I change The Loop to display all Category titles, instead of Pages associated with a single category?
**Q2:** Is there anything else I need to add, like some code to functions.php etc?
**Q3:** Would it be easier to create a custom page template, instead of pasting into a regular page?

<p>Just wanted some advice in relation to adding some custom code to my wordpress site. I am using <code>geoip</code> to check a users country code and redirect them to the relevant site when they land on my homepage.</p>
<p>Currently I include this block of <code>php</code> code at the very top of my themes <code>header.php</code> file. However I'm not sure that is the best way to go about it, would it be better off in the <code>functions.php</code> and if so is there a <code>hook</code> I can use to call this code when the homepage is about to be loaded and redirect accordingly? </p>
<pre><code>$url = $_SERVER['REQUEST_URI'];
require_once("geoip.inc");
$gi = geoip_open(dirname(__FILE__) . "/GeoIP.dat", GEOIP_STANDARD);
$country_code = geoip_country_code_by_addr($gi, $_SERVER['REMOTE_ADDR']);
geoip_close($gi);
if ($url === "/") {
//If IE go to /ie
if ($country_code === "IE") {
header("Location: http://www.wpmultisite.com/ie");
die();
}//If GB go to /uk
else if ($country_code === "GB") {
header("Location: http://www.wpmultisite.com/uk");
die();
}
}
</code></pre>
<p>I should point out I'm trying to set up a network of sites using the <code>Wordpress Multisite</code> functionality. </p>
<p>Many thanks in advance for any of your help.</p>

The answer depends on why are you moving the folder.
If you just need to folder to be moved but leave the URLs the same then you will need to adjust yout apache/nginx config files to point to the right directory when serving a request for a url of the type /wp-content/...
If you need to adjust the url as well then you need to also define appropriate `WP_CONTENT_URL`

<p>I'm building a multisite in which site admins have no "manage options" capability. The problem is that withut this cap they cannot see the "site identity" tab in the customizer, where they can change the site icon (favicon) as well as the site's name.</p>
<p>Is there a way to change the required capability to show this tab and save its contents? If not, is there a way to display the same fields as in this tab but in a custom tab in the customizer?</p>
<p>Thank you and have a nice day.</p>

**This is how I've interpreted from the wordpress [docs](https://codex.wordpress.org/Class_Reference/WP_Customize_Manager/get_setting) at least. Originally these settings were made with `add_setting` and it is where the capability was originally set. Fortunately, we can use `get_setting` to change that value. It seems to work very well for your case.**
```
function wpseo_206907_add_back_customizer_controls_for_not_admins( $wp_customize ) {
$wp_customize->get_setting( 'blogname' )->capability = 'edit_theme_options'; // or edit_posts or whatever capability your site owner has
}
add_action( 'customize_register', 'wpseo_206907_add_back_customizer_controls_for_not_admins', 1000 );
```
---
**If for some reason they don't have access to the customizer you need to give them the edit\_theme\_options capability first.**
```
function wpseo_206951_add_capability_for_non_admin() {
$roleObject = get_role( 'editor' ); // whoever should have access to theme changes
if (!$roleObject->has_cap( 'edit_theme_options' ) ) {
$roleObject->add_cap( 'edit_theme_options' );
}
}
add_action( 'admin_init', 'wpseo_206951_add_capability_for_non_admin');
```
**This will give them access to the following:**
Appearance > Widgets
Appearance > Menus
Appearance > Customize if they are supported by the current theme
Appearance > Background
Appearance > Header
**If you'd rather hide these pages all together do this:**
```
function wpseo_206907_remove_by_caps_admin_menu() {
if ( !current_user_can('manage_options') ) {
remove_menu_page('themes.php'); // Appearance Menu on Admin
remove_submenu_page( 'themes.php', 'widgets.php' );
remove_submenu_page( 'themes.php', 'nav-menus.php' );
remove_submenu_page( 'themes.php', 'theme-editor.php' );
}
}
add_action('admin_menu', 'wpseo_206907_remove_by_caps_admin_menu', 999);
```
**However, if you want them to have access to certain pages like widgets and menus, but not themes then do this instead:**
```
add_action( 'admin_init', 'wpseo_206907_lock_theme' );
function wpseo_206907_lock_theme() {
global $submenu, $userdata;
get_currentuserinfo();
if ( $userdata->ID != 1 ) {
unset( $submenu['themes.php'][5] );
unset( $submenu['themes.php'][15] );
}
}
```
**You'd also want to do this then to remove the theme change section section from the customizer:**
```
function wpseo_206951_remove_customizer_controls_all( $wp_customize ) {
if ( !current_user_can('manage_options') ) {
$wp_customize->remove_section("themes"); // Removes Themes section from backend
// To remove other sections, panels, controls look in html source code in chrome dev tools or firefox or whatever and it will tell you the id and whether it's a section or panel or control.
//Example below (uncomment to use)
// $wp_customize->remove_section("title_tagline");
// $wp_customize->remove_panel("nav_menus");
// $wp_customize->remove_panel("widgets");
// $wp_customize->remove_section("static_front_page");
}
}
add_action( 'customize_register', 'wpseo_206951_remove_customizer_controls_all', 999 );

<p>What will be best way to split large database on single site, not multi-site wp installation? <a href="https://wordpress.org/plugins/hyperdb/" rel="nofollow">HyperDB</a> is maybe for this (just, less than 10 webmasters managed to figure out how to install it, according to active installs).</p>
<p>Currently site has about 350k posts, it is on good VPS. Site is running quite fast in fronted, opening pages, browsings... But it slows down at back-end when publishing new posts, every day lots of new posts are added.</p>
<p>Site has this permalink structure:</p>
<p>sitename.com/year/month/day/postid/post-name
Practically just new posts are edited, and once published post are not changed. </p>
<p>Any idea how to speed up database writing, or better, to have published post in one database, and have new database for future posts?</p>
<hr>
<p><strong>Update:</strong></p>
<p><strong>First installation</strong>: Is installation in root of site with new database, without old, published posts, just for future posts. Permalink structure is as it was:</p>
<p>sitename.com/year/month/day/postid/post-name</p>
<p><strong>Second installation:</strong>
Created folder "2015" in root of site and installed WP in that folder with sql database of original WP installation from root, with all posts up to end of September, just permalink are changed to:</p>
<p>sitename.com/month/day/postid/post-name</p>
<p>and it will give the same URL structure as it was (because WP is in sub-folder "2015"):</p>
<p>sitename.com/year/month/day/postid/post-name</p>
<p>This approach is working when I need to split database once per year (for example for year 2014). For every past year I can have one folder named by past year and with WP installation in that folder with database with posts of that past year.</p>
<p>That way when visitor try to open URL for example:</p>
<p>sitename.com/2014/01/01/post-name-here</p>
<p>server will look first in sub-folder /2014/ and there is WP installation which will return that post.</p>
<p><strong>Problem:</strong>
When database is too big for current year I tried to split posts from current year into two databases, one have all published posts from this year up to end of September, and another will have future post.</p>
<p>I have this:</p>
<p>In root of site I have folder "2015" with WP installation with permalink structure:</p>
<p>sitename.com/month/day/postid/post-name</p>
<p>And in root WP installation with permalink structure:</p>
<p>sitename.com/year/month/day/postid/post-name</p>
<p>If I try to open URL:</p>
<p>sitename.com/2015/09/01/post-name-here</p>
<p>server will check in folder "2015" and WP installation from that folder will return post from 1st September, and it works fine.</p>
<p>If I publish new post today in WP installation in root of site it will have URL like this:
sitename.com/2015/10/29/post-name-here</p>
<p>And If I try to open it, server will look in WP installation inside of folder "2015", but that installation have posts just up to end of September, and I get 404. After that server will not look inside WP installation in root of site where that post is.</p>
<p><strong>Question:</strong></p>
<p><strong>How to make server look in WP installation inside sub folder "2015", and if there is no post in that installation to look for that post inside WP installation in root of site?</strong></p>

What will be best way to split large database on single site, not multi-site wp installation? [HyperDB](https://wordpress.org/plugins/hyperdb/) is maybe for this (just, less than 10 webmasters managed to figure out how to install it, according to active installs).
Currently site has about 350k posts, it is on good VPS. Site is running quite fast in fronted, opening pages, browsings... But it slows down at back-end when publishing new posts, every day lots of new posts are added.
Site has this permalink structure:
sitename.com/year/month/day/postid/post-name
Practically just new posts are edited, and once published post are not changed.
Any idea how to speed up database writing, or better, to have published post in one database, and have new database for future posts?
---
**Update:**
**First installation**: Is installation in root of site with new database, without old, published posts, just for future posts. Permalink structure is as it was:
sitename.com/year/month/day/postid/post-name
**Second installation:**
Created folder "2015" in root of site and installed WP in that folder with sql database of original WP installation from root, with all posts up to end of September, just permalink are changed to:
sitename.com/month/day/postid/post-name
and it will give the same URL structure as it was (because WP is in sub-folder "2015"):
sitename.com/year/month/day/postid/post-name
This approach is working when I need to split database once per year (for example for year 2014). For every past year I can have one folder named by past year and with WP installation in that folder with database with posts of that past year.
That way when visitor try to open URL for example:
sitename.com/2014/01/01/post-name-here
server will look first in sub-folder /2014/ and there is WP installation which will return that post.
**Problem:**
When database is too big for current year I tried to split posts from current year into two databases, one have all published posts from this year up to end of September, and another will have future post.
I have this:
In root of site I have folder "2015" with WP installation with permalink structure:
sitename.com/month/day/postid/post-name
And in root WP installation with permalink structure:
sitename.com/year/month/day/postid/post-name
If I try to open URL:
sitename.com/2015/09/01/post-name-here
server will check in folder "2015" and WP installation from that folder will return post from 1st September, and it works fine.
If I publish new post today in WP installation in root of site it will have URL like this:
sitename.com/2015/10/29/post-name-here
And If I try to open it, server will look in WP installation inside of folder "2015", but that installation have posts just up to end of September, and I get 404. After that server will not look inside WP installation in root of site where that post is.
**Question:**
**How to make server look in WP installation inside sub folder "2015", and if there is no post in that installation to look for that post inside WP installation in root of site?**
|
**This is how I've interpreted from the wordpress [docs](https://codex.wordpress.org/Class_Reference/WP_Customize_Manager/get_setting) at least. Originally these settings were made with `add_setting` and it is where the capability was originally set. Fortunately, we can use `get_setting` to change that value. It seems to work very well for your case.**
```
function wpseo_206907_add_back_customizer_controls_for_not_admins( $wp_customize ) {
$wp_customize->get_setting( 'blogname' )->capability = 'edit_theme_options'; // or edit_posts or whatever capability your site owner has
}
add_action( 'customize_register', 'wpseo_206907_add_back_customizer_controls_for_not_admins', 1000 );
```
---
**If for some reason they don't have access to the customizer you need to give them the edit\_theme\_options capability first.**
```
function wpseo_206951_add_capability_for_non_admin() {
$roleObject = get_role( 'editor' ); // whoever should have access to theme changes
if (!$roleObject->has_cap( 'edit_theme_options' ) ) {
$roleObject->add_cap( 'edit_theme_options' );
}
}
add_action( 'admin_init', 'wpseo_206951_add_capability_for_non_admin');
```
**This will give them access to the following:**
Appearance > Widgets
Appearance > Menus
Appearance > Customize if they are supported by the current theme
Appearance > Background
Appearance > Header
**If you'd rather hide these pages all together do this:**
```
function wpseo_206907_remove_by_caps_admin_menu() {
if ( !current_user_can('manage_options') ) {
remove_menu_page('themes.php'); // Appearance Menu on Admin
remove_submenu_page( 'themes.php', 'widgets.php' );
remove_submenu_page( 'themes.php', 'nav-menus.php' );
remove_submenu_page( 'themes.php', 'theme-editor.php' );
}
}
add_action('admin_menu', 'wpseo_206907_remove_by_caps_admin_menu', 999);
```
**However, if you want them to have access to certain pages like widgets and menus, but not themes then do this instead:**
```
add_action( 'admin_init', 'wpseo_206907_lock_theme' );
function wpseo_206907_lock_theme() {
global $submenu, $userdata;
get_currentuserinfo();
if ( $userdata->ID != 1 ) {
unset( $submenu['themes.php'][5] );
unset( $submenu['themes.php'][15] );
}
}
```
**You'd also want to do this then to remove the theme change section section from the customizer:**
```
function wpseo_206951_remove_customizer_controls_all( $wp_customize ) {
if ( !current_user_can('manage_options') ) {
$wp_customize->remove_section("themes"); // Removes Themes section from backend
// To remove other sections, panels, controls look in html source code in chrome dev tools or firefox or whatever and it will tell you the id and whether it's a section or panel or control.
//Example below (uncomment to use)
// $wp_customize->remove_section("title_tagline");
// $wp_customize->remove_panel("nav_menus");
// $wp_customize->remove_panel("widgets");
// $wp_customize->remove_section("static_front_page");
}
}
add_action( 'customize_register', 'wpseo_206951_remove_customizer_controls_all', 999 );
```

<p>I have some js scripts that are working on my site but I have found that some of the images are not showing up. I only have this issue with WordPress. So I have a pause button that shows as it's supposed to. When you press the button, it pauses the script as it's supposed to. When this happens, a new image is added to replace the pause button. The image gets inserted into the page. So it looks like this when it's playing</p>
<pre><code> <img id="pauseplay" src="http://www.example.com/wp-content/themes/theme/images/pause.png" alt="">
</code></pre>
<p>When I press the pause button, it changes to this</p>
<pre><code> <img id="pauseplay" src="images/play.png" alt="">
</code></pre>
<p>obviously this is a problem with absolute to relative links but I don't know how to fix it.
Why don't relative links work in WordPress?</p>

Relative URLs work nicely in wordpress, which is the reason for your failures. In general never use relative URLs for resources as they will most likely fail when a site is using "pretty permalinks".
Best thing for what you are doing is to "group" the graphical resources and styling in a CSS (in which resources are relative to the CSS file and not the HTML URL).
The JS alternative is to store the root of the site/theme/plugin in a JS variable and use it to construct the URL. Followin code is to take site root into consideration, but you most likely will want theme or plugin root.
```
<script>
var homeurl = '<?php echo home_url()?>';
.....
pauseImage = homeurl+"images/play.png"; // url to your play image
</script>
```

I have this code in `functions.php` that organize media upload according to its Custom Post Type (CPT).
So all images uploaded to a "Product" CPT will be inside `wp-content/uploads/product` directory.
```
add_filter("upload_dir", function ($args) {
$id = (isset($_REQUEST["post_id"]) ? $_REQUEST["post_id"] : "");
if($id) {
$newdir = "/" . get_post_type($id);
// remove default dir
$args["path"] = str_replace( $args["subdir"], "", $args["path"]);
$args["url"] = str_replace( $args["subdir"], "", $args["url"]);
// assign new dir
$args["subdir"] = $newdir;
$args["path"] .= $newdir;
$args["url"] .= $newdir;
return $args;
}
});
```
It works well, except when I delete the media, the file is still there (the database entry is deleted just fine).
I figured I need to **filter the media deletion** too, but can't seem to find the right way. Have anyone successfully set this up?
Thanks
**EDIT**
I tried adding conditional to use default folder when the post type is `post`.
```
if(get_post_type($id) === "post") {
return $args;
} else {
...
}
```
Deleting a Post's media also won't delete the file.

A small mistake, the `return` should be outside `if`
```
add_filter("upload_dir", function ($args) {
$id = (isset($_REQUEST["post_id"]) ? $_REQUEST["post_id"] : "");
if($id) {
$newdir = "/" . get_post_type($id);
...
}
return $args;

<p>I'm using WooCommerce.</p>
<p>When users go to the lost-password page, type in an email address and press "Reset password", the page just reloads. I'm not sure what wordpress normally does, but I would expect it to show a "email has been sent..." page or text.</p>
<p>The e-mail itself is sent just fine.</p>
<p>What could be wrong?</p>
<p>Similar, when the user creates a new password (by following the e-mail link), and click on "save password" the next page is the lost-password page again! That's a bit confusing.</p>

I just found another solution to my problem. The problem was that the messages just wasn't displayed properly. By adding this code to my custom CSS (under "Appearance"), the messages are now shown again:
```
.page-id-1154 .woocommerce-message, .page-id-10 .woocommerce-message {
display: block !important;
}

<p>I'm trying to create a feed where posts are pulled based off a set of authors, OR a set of categories, but I haven't had much luck. I've tried using <code>meta_query</code> and <code>tax_query</code>, but neither worked. Basically the query I'm trying to run is:</p>
<pre><code>"SELECT * FROM wp_posts WHERE author_id = $set_of_authors OR category = $set_of_categories"
</code></pre>
<p>I'm hoping to get a post object that I could just run through the loop normally, but I'll take what I can get. The only thing left I could think of was to run <code>get_results</code> with that query, but I know this is generally not the WordPress way. Is there a better way to get this query?</p>

I'm trying to create a feed where posts are pulled based off a set of authors, OR a set of categories, but I haven't had much luck. I've tried using `meta_query` and `tax_query`, but neither worked. Basically the query I'm trying to run is:
```
"SELECT * FROM wp_posts WHERE author_id = $set_of_authors OR category = $set_of_categories"
```
I'm hoping to get a post object that I could just run through the loop normally, but I'll take what I can get. The only thing left I could think of was to run `get_results` with that query, but I know this is generally not the WordPress way. Is there a better way to get this query?
|
Custom feed slug
----------------
To create a custom feed slug, e.g.
```
example.tld/billyfeed/
```
we can use the [`add_feed()`](https://codex.wordpress.org/Rewrite_API/add_feed) but we have to flush the rewrite rules to activate it. We can do that e.g. by visiting the *Permalinks* settings page in the backend.
To generate the feed we can use e.g. `do_feed_rss2()` or `do_feed_atom()`.
Here's an example:
```
add_action( 'init', function()
{
add_feed( 'billyfeed', function()
{
do_feed_rss2();
});
});
```
Modify the custom feed query
----------------------------
Next we need to modify our custom feed so that we either get the *authors* or *categories*.
Here's a workaround using the `posts_clauses` filter but without using string replacements with `str_replace()`.
```
/**
* Custom feed example.tld/billyfeed that queries authors or categories
* Supports pagination
*
* @link http://wordpress.stackexchange.com/a/207876/26350
*/
add_filter( 'posts_clauses', function( $clauses, \WP_Query $q )
{
//---------------------------------------
// Only target our custom feed
//---------------------------------------
if( ! $q->is_feed( 'billyfeed' ) || ! $q->is_main_query() )
return $clauses;
global $wpdb;
//---------------------------------------
// Input - we edit this to our needs
//---------------------------------------
$tax_query = [
[
'taxonomy' => 'category',
'field' => 'slug',
'terms' => [ 'red', 'green', 'blue' ]
]
];
$author__in = [ 1, 2, 3 ];
//---------------------------------------
// Generate the tax query SQL
//---------------------------------------
$qv = [ 'tax_query' => $tax_query, 'cat' => null, 'tag' => null ];
$q->parse_tax_query( $qv );
$tc = $q->tax_query->get_sql( $wpdb->posts, 'ID' );
//---------------------------------------
// Generate the author query SQL
//---------------------------------------
$csv = join( ',', wp_parse_id_list( (array) $author__in ) );
$authors = " {$wpdb->posts}.post_author IN ( $csv ) ";
//---------------------------------------
// Make sure the authors are set and
// the tax query is valid (doesn't contain 0 = 1)
//---------------------------------------
if( ! empty( $author__in ) && false === strpos ( $tc['where' ], ' 0 = 1' ) )
{
// Append to the current join/where parts
$clauses['join'] .= $tc['join'];
$clauses['where'] .= sprintf(
' AND ( %s OR ( 1=1 %s ) ) ', // The tax query SQL comes prepended with AND
$authors,
$tc['where']
);
}
return $clauses;
}, PHP_INT_MAX, 2 );
```
where we modify the `$tax_query` and `$author__in` to our needs.
This generates the following main 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)
WHERE
1=1
AND wp_posts.post_type = 'post'
AND (wp_posts.post_status = 'publish' OR wp_posts.post_status = 'private')
AND ( wp_posts.post_authors IN (1,2,3 ) OR ( 1=1 AND (
wp_term_relationships.term_taxonomy_id IN (1,43,120)
) ) )
ORDER BY wp_posts.post_date DESC
LIMIT 0, 10;
```
With this approach we can still paginate our feed:
```
example.tld/billyfeed/?paged=2
```

Custom feed slug
----------------
To create a custom feed slug, e.g.
```
example.tld/billyfeed/
```
we can use the [`add_feed()`](https://codex.wordpress.org/Rewrite_API/add_feed) but we have to flush the rewrite rules to activate it. We can do that e.g. by visiting the *Permalinks* settings page in the backend.
To generate the feed we can use e.g. `do_feed_rss2()` or `do_feed_atom()`.
Here's an example:
```
add_action( 'init', function()
{
add_feed( 'billyfeed', function()
{
do_feed_rss2();
});
});
```
Modify the custom feed query
----------------------------
Next we need to modify our custom feed so that we either get the *authors* or *categories*.
Here's a workaround using the `posts_clauses` filter but without using string replacements with `str_replace()`.
```
/**
* Custom feed example.tld/billyfeed that queries authors or categories
* Supports pagination
*
* @link http://wordpress.stackexchange.com/a/207876/26350
*/
add_filter( 'posts_clauses', function( $clauses, \WP_Query $q )
{
//---------------------------------------
// Only target our custom feed
//---------------------------------------
if( ! $q->is_feed( 'billyfeed' ) || ! $q->is_main_query() )
return $clauses;
global $wpdb;
//---------------------------------------
// Input - we edit this to our needs
//---------------------------------------
$tax_query = [
[
'taxonomy' => 'category',
'field' => 'slug',
'terms' => [ 'red', 'green', 'blue' ]
]
];
$author__in = [ 1, 2, 3 ];
//---------------------------------------
// Generate the tax query SQL
//---------------------------------------
$qv = [ 'tax_query' => $tax_query, 'cat' => null, 'tag' => null ];
$q->parse_tax_query( $qv );
$tc = $q->tax_query->get_sql( $wpdb->posts, 'ID' );
//---------------------------------------
// Generate the author query SQL
//---------------------------------------
$csv = join( ',', wp_parse_id_list( (array) $author__in ) );
$authors = " {$wpdb->posts}.post_author IN ( $csv ) ";
//---------------------------------------
// Make sure the authors are set and
// the tax query is valid (doesn't contain 0 = 1)
//---------------------------------------
if( ! empty( $author__in ) && false === strpos ( $tc['where' ], ' 0 = 1' ) )
{
// Append to the current join/where parts
$clauses['join'] .= $tc['join'];
$clauses['where'] .= sprintf(
' AND ( %s OR ( 1=1 %s ) ) ', // The tax query SQL comes prepended with AND
$authors,
$tc['where']
);
}
return $clauses;
}, PHP_INT_MAX, 2 );
```
where we modify the `$tax_query` and `$author__in` to our needs.
This generates the following main 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)
WHERE
1=1
AND wp_posts.post_type = 'post'
AND (wp_posts.post_status = 'publish' OR wp_posts.post_status = 'private')
AND ( wp_posts.post_authors IN (1,2,3 ) OR ( 1=1 AND (
wp_term_relationships.term_taxonomy_id IN (1,43,120)
) ) )
ORDER BY wp_posts.post_date DESC
LIMIT 0, 10;
```
With this approach we can still paginate our feed:
```
example.tld/billyfeed/?paged=2
```

<p>I duplicated my Wordpress installation to move to another server. Everything works find except one single file. I created a header-shop.php file to call a certain menu on my shop page. In the first server it was working. In the new one, it doesn't. It seems to me really crazy.</p>
<p>Here is the file:</p>
<pre><code><!doctype html>
<?php get_header(); ?>
<section class="grid wrapper shoptopmenu" id="content">
<div class="shop-menu">
<?php
$defaults = array(
'menu' => 'shop-top-menu',
'container' => 'nav',
'container_class' => 'grid wrapper',
'container_id' => 'shopmenue',
'menu_class' => 'unit full grid',
'menu_id' => '',
'echo' => true,
'fallback_cb' => 'wp_page_menu',
'before' => '',
'after' => '',
'link_before' => '',
'link_after' => '',
'items_wrap' => '<ul id="%1$s" class="%2$s">%3$s</ul>',
'depth' => 0,
'walker' => ''
);
wp_nav_menu( $defaults );
?>
</div>
</code></pre>
<p>In the first server, the HTML code is:</p>
<pre><code><section class="grid wrapper shoptopmenu" id="content">
<div class="shop-menu">
<nav id="shopmenue" class="grid wrapper">
<ul id="menu-shop-top-menu" class="unit full grid">
.....
</ul>
</nav>
</code></pre>
<p>In the new server, the HTML code is:</p>
<pre><code><section class="grid wrapper shoptopmenu" id="content">
<div class="shop-menu">
<div class="unit full grid">
<ul>
....
</ul>
</div>
</code></pre>
<p>You can see that the <code>nav</code> element and the id and class on the <code>ul</code> element are missing. Everything else is the same. Any idea before get crazy? :P</p>

I duplicated my Wordpress installation to move to another server. Everything works find except one single file. I created a header-shop.php file to call a certain menu on my shop page. In the first server it was working. In the new one, it doesn't. It seems to me really crazy.
Here is the file:
```
<!doctype html>
<?php get_header(); ?>
<section class="grid wrapper shoptopmenu" id="content">
<div class="shop-menu">
<?php
$defaults = array(
'menu' => 'shop-top-menu',
'container' => 'nav',
'container_class' => 'grid wrapper',
'container_id' => 'shopmenue',
'menu_class' => 'unit full grid',
'menu_id' => '',
'echo' => true,
'fallback_cb' => 'wp_page_menu',
'before' => '',
'after' => '',
'link_before' => '',
'link_after' => '',
'items_wrap' => '<ul id="%1$s" class="%2$s">%3$s</ul>',
'depth' => 0,
'walker' => ''
);
wp_nav_menu( $defaults );
?>
</div>
```
In the first server, the HTML code is:
```
<section class="grid wrapper shoptopmenu" id="content">
<div class="shop-menu">
<nav id="shopmenue" class="grid wrapper">
<ul id="menu-shop-top-menu" class="unit full grid">
.....
</ul>
</nav>
```
In the new server, the HTML code is:
```
<section class="grid wrapper shoptopmenu" id="content">
<div class="shop-menu">
<div class="unit full grid">
<ul>
....
</ul>
</div>
```
You can see that the `nav` element and the id and class on the `ul` element are missing. Everything else is the same. Any idea before get crazy? :P

Custom feed slug
----------------
To create a custom feed slug, e.g.
```
example.tld/billyfeed/
```
we can use the [`add_feed()`](https://codex.wordpress.org/Rewrite_API/add_feed) but we have to flush the rewrite rules to activate it. We can do that e.g. by visiting the *Permalinks* settings page in the backend.
To generate the feed we can use e.g. `do_feed_rss2()` or `do_feed_atom()`.
Here's an example:
```
add_action( 'init', function()
{
add_feed( 'billyfeed', function()
{
do_feed_rss2();
});
});
```
Modify the custom feed query
----------------------------
Next we need to modify our custom feed so that we either get the *authors* or *categories*.
Here's a workaround using the `posts_clauses` filter but without using string replacements with `str_replace()`.
```
/**
* Custom feed example.tld/billyfeed that queries authors or categories
* Supports pagination
*
* @link http://wordpress.stackexchange.com/a/207876/26350
*/
add_filter( 'posts_clauses', function( $clauses, \WP_Query $q )
{
//---------------------------------------
// Only target our custom feed
//---------------------------------------
if( ! $q->is_feed( 'billyfeed' ) || ! $q->is_main_query() )
return $clauses;
global $wpdb;
//---------------------------------------
// Input - we edit this to our needs
//---------------------------------------
$tax_query = [
[
'taxonomy' => 'category',
'field' => 'slug',
'terms' => [ 'red', 'green', 'blue' ]
]
];
$author__in = [ 1, 2, 3 ];
//---------------------------------------
// Generate the tax query SQL
//---------------------------------------
$qv = [ 'tax_query' => $tax_query, 'cat' => null, 'tag' => null ];
$q->parse_tax_query( $qv );
$tc = $q->tax_query->get_sql( $wpdb->posts, 'ID' );
//---------------------------------------
// Generate the author query SQL
//---------------------------------------
$csv = join( ',', wp_parse_id_list( (array) $author__in ) );
$authors = " {$wpdb->posts}.post_author IN ( $csv ) ";
//---------------------------------------
// Make sure the authors are set and
// the tax query is valid (doesn't contain 0 = 1)
//---------------------------------------
if( ! empty( $author__in ) && false === strpos ( $tc['where' ], ' 0 = 1' ) )
{
// Append to the current join/where parts
$clauses['join'] .= $tc['join'];
$clauses['where'] .= sprintf(
' AND ( %s OR ( 1=1 %s ) ) ', // The tax query SQL comes prepended with AND
$authors,
$tc['where']
);
}
return $clauses;
}, PHP_INT_MAX, 2 );
```
where we modify the `$tax_query` and `$author__in` to our needs.
This generates the following main 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)
WHERE
1=1
AND wp_posts.post_type = 'post'
AND (wp_posts.post_status = 'publish' OR wp_posts.post_status = 'private')
AND ( wp_posts.post_authors IN (1,2,3 ) OR ( 1=1 AND (
wp_term_relationships.term_taxonomy_id IN (1,43,120)
) ) )
ORDER BY wp_posts.post_date DESC
LIMIT 0, 10;
```
With this approach we can still paginate our feed:
```
example.tld/billyfeed/?paged=2
```

<p>I am trying to add some text to the <code>customer-order-processing</code> email from WooCommerce, and it should ONLY be added in this particular email and ONLY if chosen payment method is Paypal. I have come so far as the text is added, and only when Paypal is chosen as payment method, but the text is displayed in every email to the customer now, for example also in the <code>order-completed</code> email or <code>customer-note</code> email. I have the following:</p>
<pre><code>add_action( 'woocommerce_email_before_order_table', 'add_order_email_instructions', 0, 2 );
function add_order_email_instructions( $order, $sent_to_admin ) {
if ( 'paypal' == $order->payment_method && ! $sent_to_admin ) {
echo 'my text:';
}
}
</code></pre>
<p>I have tried with additional conditionals, like <code>! $order->has_status( 'processing' )</code>, but nothing is working.</p>

I've been trying to get post format to work for a while now, and for some reasons it is still not working the way it should.
I am creating a custom theme based on HTML5 Blank theme.
First thing I did was to add post\_formats to functions.php
```
function add_post_formats() {
add_theme_support( 'post-formats', array( 'gallery', 'quote', 'video', 'aside', 'image', 'link', 'audio' ) );}
```
Post formats are now called in wp-admin and I can see the box for choosing the post\_format in "Add new post".
I then added this code to my loop.php to set the post format to a specific post
```
<?php if (have_posts()): while (have_posts()) : the_post(); if(!get_post_format()) {
get_template_part('format', 'standard');
} else {
get_template_part('format', get_post_format());
} ?>
```
But something is still missing because each post has a format attached to it, but It does not change anything on the display. For example format-video or format-links looks exactly the same as a standard format.
In other words, embedded videos (for ex.) are not displayed on my article home page even though the post format is set and the video url is embedded in the content.

Post formats are not magic. Your theme needs to actually have a code to generate different HTML (or apply different CSS rules) for different format.
Having the theme "suuport" post formats is nice for future compatibility of the content, but by itself it doesn't do anything to how the content is displayed.

You should prefer the uninstall hook over the file if your main plugin doesn't have side effects (outputs html or writes to file/DB automatically when loaded). IMO there is too much risk (i.e. non zero) of doing the uninstall.php code wrong and open the file to direct execution from the outside.
This also help in having all the relevant code in one place.
uninstall.php, when exists, is being executed without loading the plugin code (that is the whole point of it) and therefor whatever is declared in the plugin code will not be available to uninstall.php.

<p>I'm using <code>wp_remove_get</code> to get the WordPress theme style content <strong>(style.css)</strong> and then get the theme version number. However I don't know exactly what regex I should use to get the version code:</p>
<pre><code><?php
$response = wp_remote_get( 'http://example.com/wp-content/themes/theme-name/style.css' );
if( is_array($response) ) {

?>
</code></pre>
<p>Also I'm going to get the version of about 20 themes (sites) on the same page, what I need to do to decrease the page load?</p>

The solution is simple: in the first loop, you are setting the `$amazon_link` like this:
```
$amazon_link = get_field('amazon_link', $image['ID']);
```
but in the second loop, you are setting a `$link`, like this:
```
$link = get_field('amazon_link', $image['ID']);
```
but you're still trying to echo `$amazon_link` variable later on, which has never been setup in the second loop, so it's value is still the value of the last book from the first loop.

It is faster and better.</p>\n\n<p>Example:</p>\n\n<pre><code>next_post_link( '<div class=\"nav-next\">%link</div>', 'Next project' ); \nprevious_post_link( '<div class=\"nav-previous\">%link</div>', 'Previous project' ); \n</code></pre>\n\n<p>Apart from what @s_ha_dum has said about setting the third parameter to <code>true</code>, you also need to set the fifth parameter to the taxonomy the terms belongs to if the terms does not belong to the build in taxonomy <code>category</code>. </p>\n\n<p>So, for the build in taxonomy <code>category</code>, you would do</p>\n\n<pre><code>next_post_link( '<div class=\"nav-next\">%link</div>', 'Next project', true ); \nprevious_post_link( '<div class=\"nav-previous\">%link</div>', 'Previous project', true );\n</code></pre>\n\n<p>and for a custom taxonomy, you would do</p>\n\n<pre><code>next_post_link( '<div class=\"nav-next\">%link</div>', 'Next project', true, '', 'MY_TAXONOMY' ); \nprevious_post_link( '<div class=\"nav-previous\">%link</div>', 'Previous project', true, '', 'MY_TAXONOMY' ); \n</code></pre>\n\n<p>where <code>MY_TAXONOMY</code> is the name of your custom taxonomy</p>\n"

I have this code to use with shortcode at my portfolio pages.
Everything is working fine, but I need that next and previous get the same category.
This is the code:
```
add_shortcode( 'prev', 'prev_shortcode' );
add_shortcode( 'next', 'next_shortcode' );
function next_shortcode($atts) {
global $post;
ob_start();
next_post_link( '<div class="nav-next">%link</div>', 'Next project' );
$result = ob_get_contents();
ob_end_clean();
return $result;
}
function prev_shortcode($atts) {
global $post;
ob_start();
previous_post_link( '<div class="nav-previous">%link</div>', 'Previous project' );
$result = ob_get_contents();
ob_end_clean();
return $result;
}
```
|
[`next_post_link()`](https://codex.wordpress.org/Function_Reference/next_post_link) accepts a third argument which will limit the links to the same category. There is an example of this usage in the Codex:
```
next_post_link( '%link', 'Next post in category', TRUE );
```
>
> in\_same\_term (*boolean*) (*optional*) Indicates whether
> next post must be within the same taxonomy term as the current post.
> If set to 'true', only posts from the current taxonomy term
> will be displayed. If the post is in both the parent and subcategory,
> or more than one term, the next post link will lead to the next post
> in any of those terms.
>
>
> * true
> * false
>
>
> Default: false
>
>
>
What you need, in short, is to add `, TRUE` to you function arguments:
```
next_post_link( '<div class="nav-next">%link</div>', 'Next project', TRUE );
```
And:
```
previous_post_link( '<div class="nav-previous">%link</div>', 'Previous project', True );
```

yesterday @jas helped to how to show archive by years in my nav. It works fine, but there is the second one little problem.
The @jas's solution filter me posts from all categories by year, I'd need to add filter to just one category.
The function which add me years to my navigation is:
```
add_filter( 'wp_nav_menu_objects', 'ravs_add_menu_parent_class' );
function ravs_add_menu_parent_class( $items ) {
foreach ( $items as $item ) {
//print_r($item);//print each menu item an get your parent menu item-id
// get your menu item ID use that ID in below code and you can remove this code after getting ID
}
GLOBAL $wpdb;
$years = $wpdb->get_results( "SELECT YEAR(post_date) AS year FROM wp_posts WHERE post_type = 'post' AND post_status = 'publish' GROUP BY year DESC" );
foreach($years as $year){
$link = array (
'title' => $year->year,
// 'title' =>($year->year == date('Y') ) ? 'News (Category)' : $year->year, // this is how you want to print latest year as "News (Category)"
'menu_item_parent' => '13', // my menu id is 13 ie: ID of menu name test under which years links are displayed
'ID' => '',
'db_id' => '',
'url' => '/'.$year->year // to create url of menu item
);
$items[] = (object) $link;
}
return $items;
}
```
Is there someone who helps me to extend it to category 'news' (if ID is needed, the cat's ID is '4').
Thanks for all.

If I understand you question clearly that we just need to get post in that submenus from only cat id = 4 , this will make your archive.php to work only for cat id = 4
Please add below code to **functions.php**:
```
function wpse75668_filter_pre_get_posts( $query ) {
if ( $query->is_main_query() && ! is_admin() ) {
if ( is_date() ) {
$query->set( 'cat', '4' );
}
}
}
add_action( 'pre_get_posts', 'wpse75668_filter_pre_get_posts' );
```
Thanks!

<p>I am trying to run the following query to access my WP cf7dbplugin_submits table but it keeps coming up empty. I have added my table into wp-db.php model as such:</p>
<pre><code>Added the contact form table- cf7dbplugin_submits to the following at about line 268:
var $tables = array('cf7dbplugin_submits','posts', . . .)
At around line 304 add the following:
/**
* WordPress cf7dbplugin_submits table
*/
public $cf7dbplugin_submits;
</code></pre>
<p>So the database function should find it (it has when used elsewhere in my code). But the following is consistently coming up empty for any $postid:</p>
<pre><code>function action_getpost($postid) {
global $wpdb, $out;
$out['post'] = array();
$out['uploads'] = array();
// wp_posts has one row for each submitted form.
// wp_nf_objectmeta includes a set of rows for each defined form.
$query =
"SELECT submit_time, form_name, field_value" .
"FROM $wpdb->cf7dbplugin_submits " .
"WHERE field_order = %d AND submit_time = %d ";
$queryp = $wpdb->prepare($query, array(9999, $postid));
if (empty($queryp)) {
$out['errmsg'] = "Internal error: \"$query\" \"$postid\"";
return;
}
$wpdb->show_errors( true );
$row = $wpdb->get_row($queryp, ARRAY_A);
if (empty($row)) {
$out['errmsg'] = "No rows matching: \"$postid\"";
return;
}
</code></pre>
<p>If I just run the following query in phpMyAdmin, where $postid = 1445125066.4375:</p>
<pre><code>SELECT submit_time, form_name, field_value
FROM wp_cf7dbplugin_submits
WHERE field_order = 9999 AND submit_time = 1445125066.4375
</code></pre>
<p>It produces the needed row </p>
<pre><code>submit_time form_name field_value
1445125066.4375 Demographics usernamehere
</code></pre>
<p>So why is the function returning my error of no rows matching 1445125066.4375? Any ideas?</p>

Added the contact form table- cf7dbplugin_submits to the following at about line 268:
var $tables = array('cf7dbplugin_submits','posts', . . .)
At around line 304 add the following:
/**
* WordPress cf7dbplugin_submits table
*/
public $cf7dbplugin_submits;
```
So the database function should find it (it has when used elsewhere in my code). But the following is consistently coming up empty for any $postid:
```
function action_getpost($postid) {
global $wpdb, $out;
$out['post'] = array();
$out['uploads'] = array();
// wp_posts has one row for each submitted form.
// wp_nf_objectmeta includes a set of rows for each defined form.
$query =
"SELECT submit_time, form_name, field_value" .
"FROM $wpdb->cf7dbplugin_submits " .
"WHERE field_order = %d AND submit_time = %d ";
$queryp = $wpdb->prepare($query, array(9999, $postid));
if (empty($queryp)) {
$out['errmsg'] = "Internal error: \"$query\" \"$postid\"";
return;
}
$wpdb->show_errors( true );
$row = $wpdb->get_row($queryp, ARRAY_A);
if (empty($row)) {
$out['errmsg'] = "No rows matching: \"$postid\"";
return;
}
```
If I just run the following query in phpMyAdmin, where $postid = 1445125066.4375:
```
SELECT submit_time, form_name, field_value
FROM wp_cf7dbplugin_submits
WHERE field_order = 9999 AND submit_time = 1445125066.4375
```
It produces the needed row
```
submit_time form_name field_value
1445125066.4375 Demographics usernamehere
```
So why is the function returning my error of no rows matching 1445125066.4375? Any ideas?

If I understand you question clearly that we just need to get post in that submenus from only cat id = 4 , this will make your archive.php to work only for cat id = 4
Please add below code to **functions.php**:
```
function wpse75668_filter_pre_get_posts( $query ) {
if ( $query->is_main_query() && ! is_admin() ) {
if ( is_date() ) {
$query->set( 'cat', '4' );
}
}
}
add_action( 'pre_get_posts', 'wpse75668_filter_pre_get_posts' );
```
Thanks!

<p>I was wondering if it's possible to convert this kind of shortcode:</p>
<pre><code>[card name="Muscle Band" set="XY" no="121" c="name"][/card]
</code></pre>
<p>Into this in Visual Mode (in blue-colored text):</p>
<blockquote>
<p>Muscle Band XY 121</p>
</blockquote>
<p>Basically, something that detects shortcode that's in the above format and changes it into the second format only when you look at it in Visual mode (the card name, set, and number).</p>
<p>Thank you!</p>
