"text": "<p>I didn't do this recently but in 2014, in a few WordPress projects that I need additional tables I used Laravel components. </p>\n\n<p>In WordPress, if you want to create your own tables by using wpdb and mysql queries.

When I started out with Wordpress I was anti-plugin. I wanted to add everything in my theme's `functions.php`. When I looked at the bigger picture it began making sense having and leaving some functionalities inside a plugin.
There are many write-ups on the subject of what should go into a plugin and what should go into a theme. I, for one, have done one or two posts on this subject, so do yourself the favor and read up on this. I believe it will be very helpful and insightful.
Functions in a plugin and functions in a theme's `functions.php` does exactly the same job, there is no difference. The only thing is, you cannot declare a function in plugin **and** redeclare it in your theme. This will throw a fatal error crashing the site
To answer your issue, yes, if you think logically about this, your functionality should go into a plugin as this gives functionality to your site, and not the theme. This is functionality that you would need when you switch themes. It is just easier in plugin as you don't need to write or copy this code over and over again into a new theme.

<p>I am trying to retrieve some custom post type from their specific parent category.</p>
<pre><code> <div class="tab-content">
<?php
$cat_menu = get_categories('taxonomy=menu_categorie&type=menus');
foreach($cat_menu as $menu) {
echo '<div role="tabpanel" class="tab-pane active fade" id="'.$menu->slug.'">';
$id = (int) $menu->cat_ID;
$args = array(
'post_type' => 'menus',

'cat' => $id
);
$recipes = new WP_Query($args);
if($recipes->have_posts()) : while($recipes->have_posts()) : $recipes->the_post();
echo the_title();
endwhile; endif;
echo '</div>';
}
?>
</div>
</code></pre>
<p>if I remove, in the array $args, the key 'cat', it will work but it will output ALL my menu. What I want is to be able to output my menu post type from the category_id, but I have nothing that shows up. So I guess $recipes have nothing in it, then fails. </p>
<p>Is there something I missed out to retrieve custom post type with a specific category id?</p>

Is there something I missed out to retrieve custom post type with a specific category id?

From what u have written so far it seems `menu_categorie` is the custom taxonomy. Make sure it is this only. I get a feeling that you have misses "s" from the end of `menu_categorie`
Anyways
The argument `'cat' => $id` you were using is used for default taxonomy i.e `category`.
But in your case you have custom taxonomy `menu_categorie`.
So you need to use the tax\_query.
So this is how your code will look.
```
<div class="tab-content">
<?php
$cat_menu = get_categories('taxonomy=menu_categorie&type=menus');
foreach($cat_menu as $menu) {
echo '<div role="tabpanel" class="tab-pane active fade" id="'.$menu->slug.'">';
$id = (int) $menu->cat_ID;
$args = array(
'post_type' => 'menus',
'post_status' => 'publish',
'tax_query' =>
array(
array(
'taxonomy' => 'menu_categorie',
'field' => 'id',
'terms' => $id
),
),
);
$recipes = new WP_Query($args);
if($recipes->have_posts()) : while($recipes->have_posts()) : $recipes->the_post();
echo the_title();
endwhile; endif;
echo '</div>';
}
?>
</div>
```
This should work . If it doesn't please let me know

i found this code wordpress.org . This code would work in author template.
```
<?php
global $wp_query;
$curauth = $wp_query->get_queried_object();
$post_count = $wpdb->get_var("SELECT COUNT(*) FROM $wpdb->posts WHERE post_author = '" . $curauth->ID . "' AND post_type = 'post' AND post_status = 'publish'");
?>
<h2>Post Count: <?php echo $post_count; ?></h2>
```
But if you wish to use it somewhere else then replace `$curauth->ID` with author id and `post` with the post type you want
it should work .
All the best

But if you wish to use it somewhere else then replace `$curauth->ID` with author id and `post` with the post type you want
it should work .

<p>I am new to wordpress and i am learning a lot. But i am making this intranet site and i need to make a form just like Facebook's update status where my logged in users will need to update their status or upload some images with a description on it. Then underneath that, i will need to have a comment section and like buttons.</p>
<p>I know i could use the create post form on the front page but the status won't be having a title. Attached is an image just to show what i am trying to achieve. Any ideas will be appreciated.<a href="https://i.stack.imgur.com/IPCr5.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/IPCr5.jpg" alt="This is a diagram of what i am trying to achieve"></a></p>

i found this code wordpress.org . This code would work in author template.
```
<?php
global $wp_query;
$curauth = $wp_query->get_queried_object();
$post_count = $wpdb->get_var("SELECT COUNT(*) FROM $wpdb->posts WHERE post_author = '" . $curauth->ID . "' AND post_type = 'post' AND post_status = 'publish'");
?>
<h2>Post Count: <?php echo $post_count; ?></h2>
```

it should work .

<p>I am trying to create a page that shows all users with a selection of details. One of those details is the user role it has. For each role I want to display a different string. In order to achieve this is have the following code:</p>
<pre><code>function smoelenboek_func(){
$users = get_users('orderby=nicename');
foreach ($users as $user) {
switch ($user->roles[0]) {
case 'administrator' :
echo 'Yes';
case 'member' :
echo 'No';
case 'oldmember' :
echo 'Maybe';
};
};
};
</code></pre>
<p>Now the strange thing that happens is, users with an administrator role get output "YesNoMaybe", a member role gets "NoMaybe" and oldmember gets "Maybe". Am I using the Switch-Case incorrectly? Is there something in the roles array that I'm misinterpreting? Any help is hugely appreciated. </p>

You missed break statement
This is how switch case works
```
switch ($i) {
case "apple":
echo "i is apple";
break;
case "bar":
echo "i is bar";
break;
case "cake":
echo "i is cake";
break;
}
```

I have written a function in `functions.php` that gets variables from a contact form and sends the inputs (and some other info like IP and location..) to my email.
I am starting to work on my first plugin and I want to store the parameters in a new table on the database.
How do I get the parameters from `function.php` right after the user clicks on the **send** button of the `contact form`?
|
There is three way to use `function.php` file variable into plugin file.
1. Using [global](https://codex.wordpress.org/Global_Variables). Make sure you globalize it first.
`global $my_variable;
echo $my_variable;`
2. I recommend is using WordPress built-in filter mechanism [add\_filter](https://developer.wordpress.org/reference/functions/add_filter/). You add the filter in your `functions.php` file and apply it where needed.
In `functions.php`:
```
add_filter( 'my_variable', 'return_my_variable' );
function return_my_variable( $arg = '' ) {
return '111221122';
}
```
Now you can use in your plugin files:
```
echo apply_filters( 'my_variable', '' );
```
3. Use an action hook [add\_action](https://developer.wordpress.org/reference/functions/add_action/)
In `functions.php`:
```
add_action( 'my_variable', 'echo_my_variable' );
function echo_my_variable() {
echo '888998899';
}
```
In your plugin files:
```
do_action( 'my_variable' );
```
Again, I recommend a filter because it can return a value. This is far more flexible than injecting echo calls in your plugin file. Whether you use an action hook or a filter is entirely up to you.

<p>I'm trying to get into wordpress theme development. I currently work at agency which uses Roots framework and piklist. </p>
<p>I created a custom post type into which i wanted to add an icon from font-awesome.
I wanted a more userfriendly approach in the select box inside the metabox container.</p>
<p>i was suggested this: <a href="https://github.com/tommusrhodus/FontAwesome-4.3.0-Class-Names/blob/master/array.php" rel="nofollow">https://github.com/tommusrhodus/FontAwesome-4.3.0-Class-Names/blob/master/array.php</a></p>
<p>Which I got to work somewhat, the select box has more user friendly names for the classes, however i have trouble outputing them. This is the code i use for outputing it:</p>
<pre><code> $font_awesome_icon = get_post_meta(get_the_ID(), 'font-awesome-icon');
<i class="fa <?php echo $font_awesome_icon; ?>"></i>
</code></pre>
<p>This is what i get in the output:</p>
<pre><code><i class="fa <br />
<b>Notice</b>: Array to string conversion in <b>/home/html/grg.sk/public_html/_sub/dusan/dummytest/wp- content/themes/theme/templates/blocks/block-aboutus.php</b> on line <b>19</b><br />
Array"></i>
</code></pre>
<p>However if i add array with any attributes (that don't even exist suddenly it works. I found this out by mistake when adding array to the wrong line of code... :)</p>
<pre><code>$font_awesome_icon = get_post_meta(get_the_ID(), 'font-awesome-icon',array('size' => 'whatever'));
</code></pre>
<p>So can please anyone explain to me why this doesn't work?</p>
<p>I could also include the thread from piklist, but i'm not sure if that's allowed.</p>

$font_awesome_icon = get_post_meta(get_the_ID(), 'font-awesome-icon',array('size' => 'whatever'));
```
So can please anyone explain to me why this doesn't work?
I could also include the thread from piklist, but i'm not sure if that's allowed.

There is three way to use `function.php` file variable into plugin file.
1. Using [global](https://codex.wordpress.org/Global_Variables). Make sure you globalize it first.
`global $my_variable;
echo $my_variable;`
2. I recommend is using WordPress built-in filter mechanism [add\_filter](https://developer.wordpress.org/reference/functions/add_filter/). You add the filter in your `functions.php` file and apply it where needed.
In `functions.php`:
```
add_filter( 'my_variable', 'return_my_variable' );
function return_my_variable( $arg = '' ) {
return '111221122';
}
```
Now you can use in your plugin files:
```
echo apply_filters( 'my_variable', '' );
```
3. Use an action hook [add\_action](https://developer.wordpress.org/reference/functions/add_action/)
In `functions.php`:
```
add_action( 'my_variable', 'echo_my_variable' );
function echo_my_variable() {
echo '888998899';
}
```
In your plugin files:
```
do_action( 'my_variable' );
```
Again, I recommend a filter because it can return a value. This is far more flexible than injecting echo calls in your plugin file. Whether you use an action hook or a filter is entirely up to you.

<p>I want to know the best use of adding custom <code>JS/CSS</code> to a theme.</p>
<p>I have built a small plugin which has a section to allow users to add <code>CSS/JS</code> to their theme. Now I am trying to figure out is which is the best way to do this:</p>
<blockquote>
<ol>
<li><p>Save all of the code inside an custom DB and load this as plain code inside the header/footer.</p></li>
<li><p>Save all of the code inside an custom js/css file(no DB) and add the file inside the /header/footer</p></li>
</ol>
</blockquote>
<p>Notice: these custom JS/CSS files are custom build by the users so the user can add the own rules inside the plugin.</p>
<p>Which is the better, most secure solution?</p>

I actually ran into a similar issue yesterday. A theme I was working with was adding 500+ lines of internal styles to the header which absolutely drives me nuts! I ended up finding a clever solution online to work around this which you could use for CSS. The JavaScript side I'll explain toward the bottom.
**--- :: CSS :: ---**
There's a few key points in how this code works. Since you need to handle variables in your CSS files we *need* to make sure the file given supports PHP **and** has access to WordPress functions so to get any presets. We cannot do this using a `.css` file alone so we need to fool the server into presenting our PHP file as CSS.
This is purely for testing purposes: Create a file called `customcss.php` with the following code, note the PHP [`header()`](http://php.net/manual/en/function.header.php) function needed to tell the server we're going to show `text/css`:
```
<?php
header( "Content-type: text/css; charset: UTF-8" );
$test = 'blue';
?>
body {color: <?php echo $test; ?>;}
```
Next, we need to load this file in the context of WordPress so that we still have access to functions such as `get_post_meta()` or any `global` variables. Let's include this "css" file using [WP AJAX](https://codex.wordpress.org/Plugin_API/Action_Reference/wp_ajax_(action)). Note, when including or requiring we need to use absolute paths. This will look for your plugin folder and into the `/css/` directory for your "css" php file.
```
function plugin_dynamicss() {
include_once( plugin_dir_path( __FILE__ ) . '/css/customcss.php' );
exit;
}
add_action( 'wp_ajax_plugin_dynamicss', 'plugin_dynamicss' );
add_action( 'wp_ajax_nopriv_plugin_dynamicss', 'plugin_dynamicss' );
```
Finally, we need to actually enqueue our CSS via [`wp_enqueue_scripts`](https://codex.wordpress.org/Plugin_API/Action_Reference/wp_enqueue_scripts) hook:
```
function plugin_enqueue_css() {
wp_enqueue_style(
'dynamicss', admin_url( 'admin-ajax.php' ) . '?action=plugin_dynamicss',
array(),
'',
'screen'
);
}
add_action( 'wp_enqueue_scripts', 'plugin_enqueue_css' );
```
---
**--- :: JavaScript :: ---**
Enqueueing JS with variables is much easier with [`wp_localize_script()`](https://codex.wordpress.org/Function_Reference/wp_localize_script). All you need to do is [register the script](https://codex.wordpress.org/Function_Reference/wp_register_script), [localize the script](https://codex.wordpress.org/Function_Reference/wp_localize_script) with data, and finally [enqueue the script](https://codex.wordpress.org/Function_Reference/wp_enqueue_script).
```
function plugin_enqueue_js() {
wp_register_script( 'plugin_js', plugin_dir_path( __FILE__ ) . '/js/customjs.js' );
$data = array( // Define Our Data
'robert' => 'bobbert',
'nine' => 'nein'
);
wp_localize_script( 'plugin_js', 'plugin_data', $data ); // Localize Our Data
wp_enqueue_script( 'plugin_js' );
}
add_action( 'wp_enqueue_scripts', 'plugin_enqueue_js' );
```
The 2nd parameter of `wp_localize_script()` actually defines our JS Object name. In our object if we want to get and use one of the values we can say: `alert( plugin_data.robert );` which will alert to the screen "bobbert".

<p>I thought I read that when you send in a post via email you can add the category tag with a short code. So I try this with something like </p>
<pre><code>[my-category-name]
</code></pre>
<p>But all that does is print the literal with brackets. </p>
<p>I must be missing something obvious. </p>
<p>Anyone know, offhand?</p>

What is the best approach in changing the existing table prefix within both DB and wp-config file to reflect new table prefix.
Actually, it's more the backend DB changes required.
Is there a decent plugin or can someone pls point me to the manual steps required. Just worried that I might cause issues with the DB.

You can use [phpMyAdmin](https://stackoverflow.com/questions/23960321/how-to-change-table-prefixes-in-phpmyadmin) or [MySQL Workbench](https://stackoverflow.com/questions/26888738/mysql-workbench-add-prefix-to-all-tabels) to change the prefix on all the tables at once, or you can do it one-at-a-time with a tool like SequelPro. If you need to run the SQL by hand, the syntax is…
```
RENAME TABLE `old_name` TO `new_name`;
```
Once all the table names are updated, you simply update the `$table_prefix` value in your `wp-config.php` to match the new prefix.

<p>I'm setting up a series of questions and based on the answers, I am trying to redirect to a specific page. For one example, the questions have to be answer correctly, they need to be male and 65 or older. For the other, correct questions, they need to be female and 55 or older. Here is the code I am using below. I am accessing the session variables and able to print them below the questions as I move through each question. </p>
<pre><code>add_filter( 'gform_confirmation_6', __NAMESPACE__ . '\\custom_confirmation', 10, 4 );
function custom_confirmation($confirmation, $form, $entry, $ajax) {
session_start();
if(isset($_SESSION['form'])) {
$result = array();
foreach($_SESSION['form'] as $row){
$result[] = $row;
}
if ($result[0] == 'Yes' && $result[1] == 'Male' && $result[2] >= 65 && $result[3] == 'No' && $result[5] == 'No' ) {
$confirmation = array('redirect' => esc_url(home_url('/welcome')));
}
elseif($result[0] == 'Yes' && $result[1] == 'Female' && $result[2] >= 55 && $result[3] == 'No' && $result[5] == 'No' ) {
$confirmation = array('redirect' => esc_url(home_url('/welcome')));
} else {
$confirmation = array('redirect' => esc_url(home_url('/sorry-you-do-not-qualify')));
}
return $confirmation;
}
}
</code></pre>
<p>What am I doing wrong here? The logic is not working correctly. </p>
<p>Any help would be much appreciated.</p>
<p>Thanks!</p>

If anyone runs into this problem, the answer lies in the fact that gform\_confirmation is fired after gform\_after\_submission. The logic is correct, however, the 5th session variable was not being stored before the confirmation was sent. Therefore, no variable ever equaled 'No' and it failed every time.
The solution is to call the $entry in the gform\_confirmation and use it below in the conditional logic:
```
$question6 = $entry['1'];
if(isset($_SESSION['form'])) {
$result = array();
foreach($_SESSION['form'] as $row){
$result[] = $row;
}
if ($result[0] === 'Yes' && $result[1] === 'Male' && $result[2] >= 65 && $result[3] === 'No' && $question6 === 'No' ) {
$confirmation = array('redirect' => esc_url(home_url('/welcome')));
}
```

<p>I'm looking to retrieve a specific meta value for users from the Wordpress types plugin. I know the value is stored in a wpcf-team-experience-member-type. This is a checkbox option and I'd like to retrieve a list of all selected values.</p>

<pre><code>var_dump(get_user_meta($user->ID, 'wpcf-team-experience-member-type'))

<p>I get something like this:</p>

</code></pre>
<p>wpcf seems to put all of its values inside of an array, and on top of that the checkbox values are stored in an array as well. In this case, the value I'm looking for is 'student' but that array might have multiple values.</p>
<p>How would I go about retrieving it? Thank you!</p>

As per the title, what I want to do is run a custom query that (using WP-Cron) will run once a day to check for users who registered exactly 360 days before the current date (don't need time, just date) and gather their `ID`. I have this:
```
global $wpdb;
$sql = $wpdb->prepare(
"SELECT * FROM {$wpdb->users}
WHERE {$wpdb->users}.user_registered = CURRENT-DATE-MINUS-360-DAYS";
);
$userdata = HOW-DO-I-GET-THE-RESULTS-IN-AN-ARRAY
```
Where the bit in caps represents the bit I have no idea what to do :) Any help much appreciated.

I [peeked](https://core.trac.wordpress.org/browser/tags/4.2.2/src/wp-includes/user.php#L794) into the `WP_User_Query` class and it supports a `WP_Date_Query` query on the user registration date.
So we could use:
```
$query = new WP_User_Query( $args );
```
or simply:
```
$users = get_users( $args );
```
where:
```
$args = [
'fields' => 'ID',
'number' => 8,
'date_query' => [
[ 'before' => '359 days ago midnight' ],
[ 'after' => '360 days ago midnight', 'inclusive' => true ],
]
];
```
This generates the following SQL query (*expanded view*):
```
SELECT wp_users.ID
FROM wp_users
WHERE 1=1
AND (
wp_users.user_registered >= '2014-08-10 00:00:00'
AND
wp_users.user_registered < '2014-08-11 00:00:00'
)
ORDER BY user_login ASC
LIMIT 10;
```
where today is `2015-08-05`.
It looks like we should update the Codex on [`get_users()`](https://codex.wordpress.org/Function_Reference/get_users) function, regarding the `date_query` argument.

<p>I'm having difficulty returning a list of posts. This file is contained in a plugin folder (ultimately I want to have a cron job just run the script here to delete posts with invalid urls in the given meta value). </p>
<p>I've tried using get_posts to return posts with no success. So I tried working and reworking a wp_query with still no success. </p>
<p>Also, the only way I can successfully get to the part where the array would be printed and the 'No items here' displays is if the post_status is set to inherit. Otherwise absolutely no output is generated. </p>
<p>Can anyone give me a hint to the fundamental I'm missing here? I've structured the pull correctly both when attempting the get_posts and wp_query because I recycled code structures I already successfully use in other areas of the site.

It seems that the OP have managed to solve his/her problem by doing this, which can be found at [Different menus for logged-in users](https://codex.wordpress.org/Function_Reference/wp_nav_menu#Different_menus_for_logged-in_users).
```
if ( is_user_logged_in() ) {
wp_nav_menu( array( 'theme_location' => 'logged-in-menu' ) );
} else {
wp_nav_menu( array( 'theme_location' => 'logged-out-menu' ) );
}
```
The more shorter way to achieve that is by doing this, which is [posted in new developer.wordpress.org](https://developer.wordpress.org/reference/functions/wp_nav_menu/#div-comment-208) version:
```
wp_nav_menu( array(
'theme_location' => is_user_logged_in() ? 'logged-in-menu' : 'logged-out-menu'
) );
```
The robust way to achieve that without creating two different menus, is to use a custom `'walker'` function:
1. Look for the custom walker class that your theme is using in its `wp_nav_menu()`:
```
wp_nav_menu( array(
// More arguments here..
'walker' => new Your_Theme_Custom_Nav_Walker(),
) );

2. Write a new class in your *"functions.php"*, extend `Your_Theme_Custom_Nav_Walker` class *(you can easily search its declaration by using an IDE)* or extend the `Walker_Nav_Menu` class if they're not using any custom walker, and copy the necessary function*(s)* to modify, mostly the `start_el()` function, of that walker class in their declaration. Here is the simple custom class that extends the `Walker_Nav_Menu` that I build to suit your needs:
```
class WP_Custom_Nav_Walker extends Walker_Nav_Menu {
/**

* @param string $output Passed by reference. Used to append additional content.

3. You can use that `WP_Custom_Nav_Walker` like this:
```
wp_nav_menu( array(
// More arguments here..
'walker' => new WP_Custom_Nav_Walker(),
) );
```
You can check [this answer](https://wordpress.stackexchange.com/a/196901/73330) for another example how to do that.

The simplest way is to use WordPress plugins. For example:
1. 301 SEO Redirection
2. 301 Redirects
Or use `.htaccess` file

EDIT:
As alluded to in Mark's answer below, the default `get_term_by()` returns an object. Quite why my code was getting caught up on the is-it-or-isnt-it-an-object thing, I don't know. Using `$term = get_term_by('slug', $cat_path, 'product_cat', ARRAY_A);` did the trick though, along with using array rather than object syntax to select the value I wanted.
As an aside, I realised that the above would return `false` if these product categories were nested, as there would be two (or more) slugs being returned; so I did a bit more cleaning up of the slug before attempting to get the term id from it.
Replacing:
```
$cat_path = str_replace(home_url().'/'.$cat_base.'/', '', $item->url);
```
With:
```
$path = parse_url($item->url, PHP_URL_PATH);
$path_trimmed = trim($path, '/');
$parts = explode('/', $path_trimmed);
$cat_path = end($parts);
```

Not sure why your object is returning the non-object notice, but you can set the output of `get_term_by` to `OBJECT`, `ARRAY_A`, or `ARRAY_N` - You'll want to use `ARRAY_A` and then access the term ID via `$term['term_id']`.

<p>I've created some custom columns to display my custom post types more attractively in the admin section - the columns are mostly custom fields. Mostly, this works absolutely fine, and I can sort by the custom field columns as expected.</p>
<p>However, one of the custom fields points to the post ID of a different post type. When displaying it, it looks fine, as I can grab the title of the associated post from its ID, rather than displaying the ID itself - all this is in my code below.</p>
<p>I can't figure out how to replicate this in the column sort though, or even if it's possible - I can only see how to sort by the meta-value, which is the ID of the linked post, rather than the title. </p>

I've created some custom columns to display my custom post types more attractively in the admin section - the columns are mostly custom fields. Mostly, this works absolutely fine, and I can sort by the custom field columns as expected.
However, one of the custom fields points to the post ID of a different post type. When displaying it, it looks fine, as I can grab the title of the associated post from its ID, rather than displaying the ID itself - all this is in my code below.
I can't figure out how to replicate this in the column sort though, or even if it's possible - I can only see how to sort by the meta-value, which is the ID of the linked post, rather than the title.
My code is working technically correctly, as in it's sorting by the meta value correctly, but I want to sort it alphabetically by the post title with that ID rather than the ID itself. Can this be done, and if so, how?
```
add_action( 'manage_posts_custom_column' , 'custom_columns', 10, 2 );
function custom_columns( $column, $post_id ) {
global $wpdb;
switch ( $column ) {
case 'extranet_client_area': // Extranet documents
$get_case_ID = get_post_meta( $post_id, 'extranet_client_area', true );
$get_case_name = $wpdb->get_results('SELECT post_title FROM `cn_bf_posts` WHERE `ID` = '.$get_case_ID);
echo '<a href="http://www.bishopfleminginsolvency.co.uk/wp-admin/post.php?post='.$get_case_ID.'&action=edit">'.$get_case_name[0]->post_title.'</a>';
break;
case 'extranet_document_type':
extranet_nice_document_type(get_post_meta( $post_id, 'extranet_document_type', true ));
break;
case 'extranet_document_date':
echo date('d/m/Y',strtotime(get_post_meta( $post_id, 'extranet_document_date', true )));
break;
case 'extranet_file':
echo '<a target="_blank" href="'.get_the_guid(get_post_meta( $post_id, 'extranet_file', true )).'">Download</a>';
break;
default:
break;
}
}
add_action( 'pre_get_posts', 'extranet_orderby' );
function extranet_orderby( $query ) {
if( ! is_admin() )
return;
$orderby = $query->get( 'orderby');
switch ( $orderby ) {
case 'extranet_sort_document_case':
$query->set('meta_key','extranet_client_area');
$query->set('orderby','meta_value');
break;
case 'extranet_sort_document_type':
$query->set('meta_key','extranet_document_type');
$query->set('orderby','meta_value_num');
break;
case 'extranet_sort_document_date':
$query->set('meta_key','extranet_document_date');
$query->set('orderby','meta_value');
break;
default:
break;
}
add_filter('manage_clientdocument_posts_columns','extranet_document_columns');
function extranet_document_columns($columns) {
$columns = array(
'cb'=>'<input type="checkbox" />',
'extranet_client_area' => __( 'Case Name' ),
'title' => __( 'Document Name' ),
'extranet_document_type' => __( 'Document Type' ),
'extranet_document_date' => __( 'Document Date' ),
'extranet_file' => __( 'Download link' )
);
return $columns;
}
add_filter( 'manage_edit-clientdocument_sortable_columns', 'my_sortable_clientdocuments_columns' );
function my_sortable_clientdocuments_columns( $columns ) {
$columns['extranet_client_area'] = 'extranet_sort_document_case';
$columns['extranet_document_type'] = 'extranet_sort_document_type';
$columns['extranet_document_date'] = 'extranet_sort_document_date';
return $columns;
}
```
|
Building on Phil's answer:
Made the following change to the switch:
```
case 'extranet_sort_document_case':
add_filter('posts_join', 'extranet_clientdocument_case_join');
add_filter('posts_fields', 'extranet_clientdocument_case_fields');
add_filter('posts_orderby', 'extranet_clientdocument_case_order');
break;
```
and wrote the following functions:
```
function extranet_clientdocument_case_join($join) {
global $wpdb;
$join .= " LEFT JOIN ".$wpdb->postmeta." AS case_ids ON (".$wpdb->posts.".ID = case_ids.post_id AND case_ids.meta_key = 'extranet_client_area')
LEFT JOIN ".$wpdb->posts." AS case_names ON (case_names.ID = case_ids.meta_value) ";
return $join;
}
function extranet_clientdocument_case_fields($fields) {
$fields.=", case_names.post_title";
return $fields;
}
function extranet_clientdocument_case_order($order_by) {
if(isset($_GET['order'])) $direction = $_GET['order'];
else $direction = 'ASC';
$order_by = 'case_names.post_title '.$direction;
return($order_by);
}
```
This worked in terms of making the column sortable by the post name of the related custom post, rather than by the metadata itself. However, it created a new problem in that the Title of the main post being listed, which is unusually the second column, now turned into the post title of the related post. I fixed this with the following additional code:
```
function restore_original_title($title) {
global $wpdb;
$post_id = get_the_ID();
$get_document_name = $wpdb->get_results('SELECT * FROM `wp_posts` WHERE `ID` = '.$post_id);
$title = $get_document_name[0]->post_title;
return $title;
}
```
and added the following additional filter:
```
add_filter( 'the_title', 'restore_original_title', 10, 2 );
```

You could always try using the `wp_login` action hook:
```
function custom_check_for_user($user_login, $user) {
if($user->ID == 123) { // Where 123 is the particular user's ID
// Do something here, eg. PHP mail() function
}
}
add_action('wp_login', 'custom_check_for_user', 10, 2);

I should look at caching plugins because it makes things faster, better and worked for you. The problem with that answer is that most caching plugins don’t do much for logged in users.
Most sites have is that non-logged in users should get pre-cached pages that load super fast, and logged-in users are the authors and admins who are working on the back-end, and don’t need the same level of performance. And for most sites, this works. But membership sites are a bit different.
The end user is a logged-in user. So you need a solution that works for logged-in users. Additionally, membership sites are often filled with user-specific data (like menus, sidebar widgets, content..etc) that needs to be current. So full page caching isn’t a solution – from a plugin or hosting provider.
Instead, what you need is part of page caching.
**1. Part of page caching:**
these kinds of approaches are neither in abundance, nor are they often talked about when you’re evaluating a membership plugin. I’m to blame too. There’s a great article explaining why it’s not great by [Austin Gunter of WP Engine](http://wpengine.com/2013/02/wordpress-transient-api/) on their blog. Suffice to say, if your options table is growing like crazy, you may be doing it wrong.
BTW, [garbage collection for transients](http://core.trac.wordpress.org/ticket/20316) (an issue raised in Austin’s article) may get added to WordPress in 3.7
**2. Fragment caching:**
You can use a little class created by Mark Jaquith. He calls it [fragment caching](http://markjaquith.wordpress.com/2013/04/26/fragment-caching-in-wordpress/),
but it’s not different from partial page caching. You’d want to check out this article that has the code in it, and read the comments.
I think this is a pretty powerful option for a lot of situations, but scaling a membership site is all about limiting the application processing side of things.
So finally there is one option that you need to try cache only database do not catch page data, browser data. I do not proposed to use [W3 Total Cache](https://wordpress.org/plugins/w3-total-cache/) but check it once this plugin may be your solution.

<p>We know that we can check if the particular post has a term by using this code: </p>

<p>I was wondering if there is a code to check if a particular post does not have a particular term.

```
longform_the_related_posts_child () {

'posts_per_page' => 4,
) );
}
```

I have gone through your code and found that the function `longform_the_related_posts` displays 8 related posts. This function is defined in functions.php of parent theme and called in single.php.
Thus, to override the function, follow below steps -
1. Create another function that displays 4 related posts in functions.php of child theme. (As you have already created function `longform_the_related_posts_change()` )
2. Copy the file `single.php` from parent to child theme and replace the line 47
From
```
echo longform_the_related_posts();
```
To
```
echo longform_the_related_posts_change();
```
This would call the function that display 4 posts.
Hope this helps.

I am developing a WP theme with MVC approach. It only have `index.php`, `functions.php` and `styles.css` on the parent directory. So, I do not want to place page templates on it rather then I want to programmatically provide them from View classes while functionality from edit screen stays the same.
Users need to have page templates select option on the edit screen. How do I successfully add Items to the template dropdown?
I tried to hook into [`theme_page_templates`](https://core.trac.wordpress.org/browser/trunk/src/wp-includes/class-wp-theme.php#L1022) filter.
**Example code:**
```
add_filter( 'theme_page_templates', function($templates){
$templates['my-page-template.php'] = "My Page Template";
return $templates;
});
```
This does not work because of the use of [`array_intersect_assoc()`](http://php.net/manual/en/function.array-intersect-assoc.php) on the filtered array, which removes the added page template item. I don't understand why this function is used. It seems you can only remove page template from the list but can not add a new one using the given filter.
Is there any other way around?

I thought I would provide you with another approach. It is also a bit hackish, but it is general purpose and allows you to simply register the filename and label that you want to use, like so:
```
if ( class_exists( 'WPSE_196995_Page_Templates' ) ) {
WPSE_196995_Page_Templates::register_page_template(
'My Page Template',
'my-page-template.php'
);
}
```
You could add the above code to your theme's `functions.php` file.
To enable the above to actually work I implemented a self-contained class that could be used as a plugin or just copied into `functions.php`:
```
<?php
/**
* Plugin Name: WPSE 196995 Page Templates
*
* Class WPSE_196995_Page_Templates
*
* Allows registering page templates via code.
*/
class WPSE_196995_Page_Templates {
static $registered_templates = array();
static function on_load() {
/**
* Add registered page templates to 'page_template' cache.
* @note This hook is called just before page templates are loaded
*/
add_action( 'default_page_template_title', array( __CLASS__, '_default_page_template_title' ) );
}
/**
* Register page templates
*
* @param string $label
* @param string $filename
*/
static function register_page_template( $label, $filename ) {
self::$registered_templates[ $filename ] = $label;
}
/**
* Add registered page templates to 'page_template' cache.
*
* @param string $title
*
* @return string mixed
*/
static function _default_page_template_title( $title ) {
/**
* @var WP_Theme $theme
*/
$theme = wp_get_theme();
/**

The class provides the `register_page_template()` method, of course, but to actually add your page template it updates the value for `'page_templates'` set in the object cache.
It is a bit hacky because WordPress made most methods and properties of the `WP_Theme` class `private`, but fortunately they used the publicly-accessible WordPress object cache to store the values. And by updating the object cache in the `'default_page_template_title'` hook, which is called just before the page templates dropdown is generated and sent to the browser, we can get WordPress to display your page template(s), as you desired.

<p>I've got a True/False value added to posts (Exclusive versus Curated) that was added via Advanced Custom Fields. How do I get that value to show up as a column on the Post list (/wp-admin/edit.php) to allow editors to quickly sort via that field?</p>
<p>I found this example (<a href="http://code.tutsplus.com/articles/add-a-custom-column-in-posts-and-custom-post-types-admin-screen--wp-24934" rel="nofollow">http://code.tutsplus.com/articles/add-a-custom-column-in-posts-and-custom-post-types-admin-screen--wp-24934</a>) for adding the post thumbnail, but do not know how to adjust to pull and ACF field in instead.</p>
<p>Field name is company_exclusive and type is True/False.</p>
<p>Any pointers would be appreciated.</p>

You've got your action/filter names slightly off:
```
// For registering the column
add_filter( 'manage_posts_columns', 'custom_posts_table_head' );
// For rendering the column
add_action( 'manage_posts_custom_column', 'custom_posts_table_content', 10, 2 );

how i can get posts via MYSQL from posts where language is 'en' and 'ru'
I have this query
```
$sql = "SELECT p1.*, wm2.meta_value
FROM wp_posts p1
LEFT JOIN wp_postmeta wm1 ON ( wm1.post_id = p1.ID
AND wm1.meta_value IS NOT NULL
AND wm1.meta_key = '_thumbnail_id' )
LEFT JOIN wp_postmeta wm2 ON ( wm1.meta_value = wm2.post_id
AND wm2.meta_key = '_wp_attached_file'
AND wm2.meta_value IS NOT NULL )
WHERE p1.post_status= 'publish' AND p1.post_type='post' ORDER BY p1.post_date DESC Limit 3";
```
I use WPML plugin.
|
I resolved creating SQL query:
```
SELECT posts.post_title, posts.post_content, trans.element_type,
trans.language_code
FROM wp_posts AS posts
INNER JOIN wp_icl_translations AS trans
ON posts.ID = trans.element_id
INNER JOIN wp_postmeta AS meta
ON posts.ID = meta.post_id
WHERE trans.element_type = 'post_product'
AND trans.language_code = 'de'
```
This is added only if you need something on post\_meta:
```
...
INNER JOIN wp_postmeta AS meta
ON posts.ID = meta.post_id
...
```
It was my solutions to get all post by language `trans.language_code = 'de'`, `trans.language_code = 'es'`, `trans.language_code = 'en'` ...

<p>I have a plugin that prepends an upvote box to <code>the_content</code> of a single post, sends data via AJAX back to the main plugin PHP file and calls a function to update a database value on success.</p>
<p>Here is the PHP callback from the AJAX:</p>
<pre><code>function update_parlay_points() {
//Update Parlay Points field on database with points from Post request.
//global $post;
//$post_id = $post->ID;
$post_id = get_the_ID();
$points = $_POST['score'];
$update_points = "UPDATE wp_posts
SET parlay_points = '$points'
WHERE id = $post_id";
var_dump( $post_id );
echo $update_points;
global $mysqli;
$mysqli->query( $update_points ) or die( "Query failed" );
wp_die();
}
</code></pre>
<p>In Chrome's Developer tools, this gives me:</p>
<blockquote>
<p>bool(false) UPDATE wp_posts SET parlay_points = '26' WHERE id = Query
failed</p>
</blockquote>
<p>As you can see, I tried declaring the <code>$post</code> variable as global to account for failures due to being outside of the Loop. The content that triggers the AJAX request is prepended to <code>the_content</code>, so I am not sure if I need to "enter" the Loop again somehow. I tried <code>if ( have_posts() )</code> and <code>if ( is_single() )</code> before <code>get_the_ID()</code> with no success. The Loop, in general, really confuses me. </p>
<p>I have also tried accessing <code>$post->ID</code> from the action hook <code>the_post</code>. Strangely enough, I am able to successfully echo the current post's ID but cannot store it in a globally scoped variable. </p>
<pre><code>$post_id = Null;

function wp_store_post_info() {

function update_parlay_points() {

<p>This does not work either:</p>

The problem is **not** that the post is *"outside of the loop"*, problem is that AJAX request is a completely separate HTTP request.
When you do an AJAX request, is just like you are opening a new window on browser and open the url in this separate window. It means that the script that handles the AJAX request knows **nothing** about the page that sent the request.
If you need to process a specific post in the AJAX request, you need to send the post ID to process as part of the AJAX request data.

<p>I'm overriding WooCommerce's default search query to include searching by SKU as well.</p>
<pre class="lang-php prettyprint-override"><code>// default search query
$query_default_search = new WP_Query(
array(
"post_type" => "product",
"s" => $search_query
)
);
// SKU query
$query_search_by_sku = new WP_Query(
array(
"post_type" => "product",
"meta_query" => array(
array(
"key" => "_sku",
"value" => $search_query,
"compare" => "LIKE"
)
)
)
);
</code></pre>
<p>If the default search query doesn't return any posts, I assume that an SKU has been entered and I run the SKU query. However, I want to merge both query arguments into one <code>WP_Query</code> call, rather than merging the results of both queries using <code>array_merge</code>.
If both queries had meta-query, I could use an OR relation, but this is different.</p>
<p>How can this be done?</p>

<p>There is one other post I've <a href="https://wordpress.stackexchange.com/questions/95836/list-of-all-existing-wordpress-plugins">found on StackOverflow</a> regarding this which recommends <a href="http://plugins.svn.wordpress.org/" rel="noreferrer">using the subversion repository.</a></p>
<p>I'd like to do something that organizes them by number of downloads.</p>
<p>I think this is probably possible using the WordPress.org API, but I'm not positive. My attempts thus far have failed. Any ideas?</p>

I'm looking for a way to get the list of all plugins listed in the [WordPress.org Plugin Directory](https://wordpress.org/plugins/).
There is one other post I've [found on StackOverflow](https://wordpress.stackexchange.com/questions/95836/list-of-all-existing-wordpress-plugins) regarding this which recommends [using the subversion repository.](http://plugins.svn.wordpress.org/)
I'd like to do something that organizes them by number of downloads.
I think this is probably possible using the WordPress.org API, but I'm not positive. My attempts thus far have failed. Any ideas?
|
You can start with something like this:
```
https://api.wordpress.org/plugins/info/1.2/?action=query_plugins&request[page]=1&request[per_page]=400
```
I think it's self-explanatory.

<p>My application has >10 <code>user_roles</code>, each able to perform completely different tasks, provided with an custom backend and no access to <code>wp-admin</code>. </p>
<p>The extra functionality each <code>user_role</code> gets to use is handled via multiple plugins. Each <code>user_role</code> interacts on the same data (posts, taxonomies etc.)</p>
<p>The idea I had is to use a single installation per one or more <code>user_roles</code> connected to a single database to share users, posts etc but with different plugins loaded, so simply a separate <code>wp_options</code> table. </p>
<p>The goal is to provide independent login areas(e.g subdomains, I don't want partners to use the same login as customers), easier routing (different permalinks and rewrites for each role) and less time checking for permissions of logged in users on protected sections of the site.

<p>My guess is, that a nice side effect would be a significant speed boost since the main site for customers is powered by <code>woocommerce</code> and I wouldn't need to activate <code>woocommerce</code> on other instances or vice versa... custom plugins would not be loaded in the installation powering the user/customer frontend.</p>

<p><strong>Update:</strong></p>
<p>The question how to keep the modified version of wpdb in case of updates, or how to use custom table names besides CUSTOM_USER_TABLE was answered in a wordpress support ticket.
The solution is to extend the wpdb-class, alter the table names in the <code>tables</code> function, save it as db.php to wp-content and use it as a drop-in. This way you can define custom names for all tables and avoid problems on updating core. (See: <a href="https://core.trac.wordpress.org/ticket/33320" rel="nofollow noreferrer">#33320</a>) </p>

Sounds like you are trying hard to shot yourself and you will likely succeed. Every framework has its own assumptions and limitation so if the assumptions of wordpress do not fit your needs then just don't use wordpress for the project.
If you (ok, probably the client) have decided that for reasons of cost, delivery time and maintainability wordpress should be used then you should strive to use the built-in wordpress tools instead of trying to go around them and re-inventing things just because if you were using framework X you would have done it that way. the more aligned you are with the wordpress core development practices the happier you will be (unless you are trying to ensure job security ;).
Sorry for the very meta answer but from your description it sounds like you don't want to do this project in wordpress although I didn't read here anything which might be problematic in wordpress and there is no need doing all the hacks that you think you should do.

During the vanilla WP core load the current user is being set up in `$wp-init()` which is after theme load and before `init` hook. This is in line with good practice of functionality getting hooked to `init` or later.
However it is also common practice to call related functions, such as `current_user_can()` *earlier* than that. It is by definition required for plugins that work with earlier stages of load process (my Toolbar Theme Switcher plugin would be an example).
Documentation makes no claims for or against this practice (that I could find).
However some plugins seem to hook into user–related functionality and expect the post–`init` state at all times.
For example bbPress throws following notice:
```
// If the current user is being setup before the "init" action has fired,
// strange (and difficult to debug) role/capability issues will occur.
if ( ! did_action( 'after_setup_theme' ) ) {
_doing_it_wrong( __FUNCTION__, __( 'The current user is being initialized without using $wp->init().', 'bbpress' ), '2.3' );
}
```
For quick demonstration throw this into core's definition of `current_user_can()`:
```
function current_user_can( $capability ) {
if ( ! did_action('after_setup_theme') ) {
echo wp_debug_backtrace_summary();
}
```
Who is “right” in this situation? Is there a canonical determination about allowed / forbidden usage of user–related functions before `init` ?
|
The only prerequisite for `current_user_can()` is an existing `wp_get_current_user()`. The latter is defined in `pluggable.php`, so you can use it after `plugins_loaded`.
The `_doing_it_wrong()` call you are citing in your question is wrong for itself. My guess is that you took that from BuddyPress or bbPress. Both are running into a recursion if they don't wait that long. There are other, better ways to prevent the recursion.
In some cases, like [changing the locale](https://github.com/inpsyde/multilingual-press/issues/88), you *have* to access the current user object earlier, so waiting for `after_setup_theme` isn't even an option.

function meta_val( $key = '', $type = 'post', $status = 'publish' ) {

There may not be a need for a custom query, but I'd recommend it rather than hitting the database:
- once for the WP\_Query
- once more for each post entry
And then manually working out the math in PHP. Do it all at once with one MySQL statement.
```
select sum(PM.meta_value) from wp_postmeta PM
join wp_posts P on P.ID = PM.post_id
where P.post_type='page'
and PM.meta_key='test'
```
With your code above, replace the `$r=...` line with this:
```
$r = $wpdb->get_results( $wpdb->prepare( "
SELECT SUM(pm.meta_value) FROM {$wpdb->postmeta} pm
LEFT JOIN {$wpdb->posts} p ON p.ID = pm.post_id
WHERE pm.meta_key = '%s'
AND p.post_status = '%s'
AND p.post_type = '%s'
", $key, $status, $type ) );
```
`$r[0]` should be your total. :)

<p>firstly i know i have to add some code explaining what i have done before.</p>
<p>But honestly i had tried more than ten tutorial concerning wordpress post slider based on flexslider or bxslider or other trics with jquery but seriously guys I don't where is the problem, i can't show slider the best thingi show is a list of post image and content vertically.</p>
<p>So my question is how to create a wordpress post slider?</p>
<p>PS. i had some linked jquery , those files could interrupt the slider. post</p>

firstly i know i have to add some code explaining what i have done before.
But honestly i had tried more than ten tutorial concerning wordpress post slider based on flexslider or bxslider or other trics with jquery but seriously guys I don't where is the problem, i can't show slider the best thingi show is a list of post image and content vertically.
So my question is how to create a wordpress post slider?
PS. i had some linked jquery , those files could interrupt the slider. post

There may not be a need for a custom query, but I'd recommend it rather than hitting the database:
- once for the WP\_Query
- once more for each post entry
And then manually working out the math in PHP. Do it all at once with one MySQL statement.
```
select sum(PM.meta_value) from wp_postmeta PM
join wp_posts P on P.ID = PM.post_id
where P.post_type='page'
and PM.meta_key='test'
```
With your code above, replace the `$r=...` line with this:
```
$r = $wpdb->get_results( $wpdb->prepare( "
SELECT SUM(pm.meta_value) FROM {$wpdb->postmeta} pm
LEFT JOIN {$wpdb->posts} p ON p.ID = pm.post_id
WHERE pm.meta_key = '%s'
AND p.post_status = '%s'
AND p.post_type = '%s'
", $key, $status, $type ) );
```
`$r[0]` should be your total. :)

<p>I have done this so many times but facing problems with meta boxes and wp_editor these days, lot of notices, errors and strange behaviour.</p>
<p>I have been able to solve problem with meta boxes notices and save . The main problem was nonce. The nonce i was using was for plugin usage. But my code is inside the theme so now i am unable to save the value in metabox and no more notices for metaboxes.</p>
<p>But now i get notice <code>Notice: Undefined variable: main_detail</code> in for wp_editor.

You forgot to declare the variable `$main_detail`. Since it's a meta field you need to retrieve it first before you add it.
```
$main_detail = get_post_meta($post->ID, '_main_detail', true);
```
Also, I can see that some errors in your code.
```
echo '<label >';?><?php _e( 'short description:' );?></label>
```
Should be..
```
echo '<label >' . _e( "short description:" ) . '</label>';
```
And, you also need to add the key `_main_detail` in your `$performer_meta` array in order to save it.

<p>I have a situation where i have about 5000 imported records in a custom post type (travel) with a taxonomy category (country). Since i import from several different locations and each source seems to use a different description for some countries i want to update the term reference of that post to a uniform description.</p>
<p>So say the taxonomy 'country' has, amongst others, these values:</p>
<pre><code>
+---------+-------------+
| term_id | name |
+---------+-------------+
| 1248 | Zuid Afrika |
+---------+-------------+
| 3845 | zuid-afrika |
+---------+-------------+
</code></pre>
<p>I want to update the term reference to 'country' that has a duplicate in each 'travel' post to a new defined id. </p>
<pre><code>
$terms = array(
'3845' => '1248'
);
$args = array(
'posts_per_page' => -1,
'post_type' => 'travel',
'post_status' => 'publish'
);
global $post;
$my_query = new WP_Query($args);
if($my_query->have_posts()){

/*

*/
if(in_array($post->term_id,$terms){
update term reference with value $terms[$post->term_id];
}
}
endwhile;
wp_reset_query();
}
</code></pre>
<p>Any help would be really appreciated because i'm pretty much stuck right now</p>
<p><strong>Edit:</strong>
I don't want to delete the taxonomy categories because this scripts will run after the imports so if the duplicates are deleted they will be imported straight back but with a different term id</p>

<p>I am using a custom post type that uses two taxonomies "colour" and "style". I have a script (<a href="https://stackoverflow.com/questions/31672345/sorting-custom-taxonomy-term-page-in-wordpress/">from this thread</a>) which groups them together so when you are on a colour taxonomy page they are grouped by style like this:</p>
<h2>Blue > Style 1</h2>
<ul>
<li>Product 1 </li>
<li>Product 2 </li>
<li>Product 3 </li>
<li>Product 4 </li>
<li>Product 5</li>
</ul>
<h2>Blue > Style 2</h2>
<ul>
<li>Product 1 </li>
<li>Product 2 </li>
<li>Product 3 </li>
<li>Product 4 </li>
<li>Product 5</li>
</ul>
<p>Now this all works great but it returns EVERY post. I want to limit it to the first three posts for each style. I know I can do something like the following but it limits posts for the whole page not per style. Any help? :)</p>
<pre><code>//limit to three per style
add_action('pre_get_posts', 'change_tax_num_of_posts' );
function change_tax_num_of_posts( $wp_query ) {
if( is_tax('colour') && is_main_query() ) {
$wp_query->set('posts_per_page', 3);
}
}
</code></pre>

I am using a custom post type that uses two taxonomies "colour" and "style". I have a script ([from this thread](https://stackoverflow.com/questions/31672345/sorting-custom-taxonomy-term-page-in-wordpress/)) which groups them together so when you are on a colour taxonomy page they are grouped by style like this:
Blue > Style 1
--------------
* Product 1
* Product 2
* Product 3
* Product 4
* Product 5
Blue > Style 2
--------------
* Product 1
* Product 2
* Product 3
* Product 4
* Product 5
Now this all works great but it returns EVERY post. I want to limit it to the first three posts for each style. I know I can do something like the following but it limits posts for the whole page not per style. Any help? :)
```
//limit to three per style
add_action('pre_get_posts', 'change_tax_num_of_posts' );
function change_tax_num_of_posts( $wp_query ) {
if( is_tax('colour') && is_main_query() ) {
$wp_query->set('posts_per_page', 3);
}
}
```

As I have stated in comments, this will take some work. In short, you will need the following:
* Get all the terms from the `style` taxonomy. Here we would only want the term ids
* Get the current `tax_query` from the `colour` taxonomy. Use each term from the `style` taxonomy and create a new `tax_query` to get posts from the current page's term and the term being looped over from the `style` taxonomy
* Run a custom query on each term from the `style` taxonomy to get an array of post ids from each term. Here you would want to add all your custom parameters. We will use the order from this custom queries as post order
* Pass the array of post ids to the main query. Here you would not want to add custom sorting etc. We will use the sequence of the post ids in the post id array for sorting
FEW NOTES BEFORE THE CODE:
--------------------------
* The code requires PHP 5.4+ due to the use of short array syntax (`[]`). You should also not be using any version older than PHP5.4. If you however do, just change the short array syntax to the old array syntax (`array()`). For example, `get_terms( $taxonomy, ['fields' => 'ids'] )` should become `get_terms( $taxonomy, array( 'fields' => 'ids' ) )`
* I have build in a transient system to reduce the extra strain coming from all the extra work that we need to do. This transient is set to expire in a week, you can adjust this to be longer or shorter. The transient will be automatically deleted when a new post is published, deleted, undeleted or updated
* I have commented the code very well so you can follow and make some kind of sense from what I was doing as I went along
* You can extend and modify as needed. Make sure to check out my comments
* With this new code, you can scrap my complete idea of sorting as described in [my linked answer on SO](https://stackoverflow.com/a/31705710/1908141). The code given in this answer should take care of this sorting. Any adjustments that you would want to make should be done in the custom queries and `get_terms` calls. Just remember to flush your transients after each modification, or better, uncomment the transient calls and return to normal once you are happy with all your modifications
THE CODE:
---------
As always, we will be using `pre_get_posts` to alter the main query as needed
```
add_action( 'pre_get_posts', function ( $q )
{
if ( !is_admin() // Targets only front end queries
&& $q->is_main_query() // Targets only main query
&& $q->is_tax( 'colour' ) // Targets only taxonomy pages
) {
/**
* To save on the extra work that we need to do to get our results,
* lets save everything in a transient. We will save the string of post ids
* in the transient.
*
* We will only delete and recreate this transient when a new post is published,
* deleted, undeleted or updated. This will save us a lot of extra hard work
* on every page load

*
* Note, this should NOT be longer that 45 characters else the transient will be regenerated
* on each page load. Transients are expensive to create, so don't want to recreate this on every

This will take care of everything except the flushing of the transients on post publish, delete, etc
The following code will take care of this. Everytime a post is updated, published, trashed or untrashed, the `transition_post_status` hook fires, so we will use that logic to delete all our transients which contains part of the `colourtax_` name
```
add_action( 'transition_post_status', function ()
{
global $wpdb;
$wpdb->query( "DELETE FROM $wpdb->options WHERE `option_name` LIKE ('_transient%_colourtax_%')" );
$wpdb->query( "DELETE FROM $wpdb->options WHERE `option_name` LIKE ('_transient_timeout%_colourtax_%')" );
});

For each post, I want to send an email once it has been published. The email address is stored in a custom field.
I have added a custom field . I have got `your_email` for the 'name'and the value is my email address (as a test).
I have got the following code in functions.php :
```
function ik_send_email($post_id){
$email_address = get_post_meta($post_id, 'your_email', true);
$subject = "Your Subject Here!";
$body = "Thank you for your submission! Your story has been approved!";
$headers = 'From: From Address <[email protected]>' . "\r\n";
if(wp_mail($email_address, $subject, $body, $headers)){
//mail sent!
} else {
//failure!
}
}
add_action('publish_post','ik_send_email');
```
So once I click 'published' it should send an email to the address entered in the custom field, but I'm not getting an email? Any tips someone can give please?

If I am on a product archive page then how can I get current product category ID in product archive page. I am using this but no result:
```
global $wp_query;
$category_name = $wp_query->query_vars['product_cat'];
$category_object = get_term_by('name', $category_name, 'product_cat');
$category_id = $category_object->term_id;
```
|
I solve This To get the current category ID.
```
$cate = get_queried_object();
$cateID = $cate->term_id;
echo $cateID;
```
and it works like a charm.

I'm not sure why EliasNS' answer is marked correct, as far as I'm aware (and from the [documentation](http://es1.php.net/manual/en/datetime.construct.php)), the second parameter of `DateTime::__construct()`, if provided, should be a `DateTimeZone` instance.
The problem then becomes, how we do we create a `DateTimeZone` instance. This is easy if the user has selected a city as their timezone, but we can work around it if they have set an offset by using the (deprecated) Etc/GMT timezones.
```
/**
* Returns the blog timezone
*
* Gets timezone settings from the db. If a timezone identifier is used just turns
* it into a DateTimeZone. If an offset is used, it tries to find a suitable timezone.
* If all else fails it uses UTC.
*
* @return DateTimeZone The blog timezone
*/
function wpse198435_get_blog_timezone() {
$tzstring = get_option( 'timezone_string' );
$offset = get_option( 'gmt_offset' );
//Manual offset...
//@see http://us.php.net/manual/en/timezones.others.php
//@see https://bugs.php.net/bug.php?id=45543
//@see https://bugs.php.net/bug.php?id=45528
//IANA timezone database that provides PHP's timezone support uses POSIX (i.e. reversed) style signs
if( empty( $tzstring ) && 0 != $offset && floor( $offset ) == $offset ){
$offset_st = $offset > 0 ? "-$offset" : '+'.absint( $offset );
$tzstring = 'Etc/GMT'.$offset_st;
}
//Issue with the timezone selected, set to 'UTC'
if( empty( $tzstring ) ){
$tzstring = 'UTC';
}
$timezone = new DateTimeZone( $tzstring );
return $timezone;
}
```
Then you can use it as follows:
```
$time = new DateTime( null, wpse198435_get_blog_timezone() );
```

It's actually pretty simple to change the title in content-product.php, but you won't be able to do it with a hook. Near the top of the file, you should see this line:
```
Override this template by copying it to yourtheme/woocommerce/content-product.php
```
All you have to do is copy the file to the above directory, replacing "yourtheme" with your theme's actual folder name, and make your desired edits to the new file.
**A little more background on hooks**
The title in the default content-product.php template file is outputted like this, which is defined in wc-template-functions.php if you search for woocommerce\_template\_loop\_product\_title() it echos the below title:
```
<h3><?php the_title(); ?></h3>
```
In order to change the title with a hook, you'd need to change the above line to this, but you can't do this without changing the wc-template-functions.php file. So what you can do is comment out the action in the content-product.php file:
```
//do_action( 'woocommerce_shop_loop_item_title' );
```
and then add the below line:
```
?><h3><?php echo apply_filters( 'my_filter_name', get_the_title() ); ?></h3><?php
```
so the saved version looks like this:
```
//do_action( 'woocommerce_shop_loop_item_title' );
?><h3><?php echo apply_filters( 'my_filter_name', get_the_title() ); ?></h3><?php
```
Then, you would need to add the following to your theme's functions.php file which will pass the contents of get\_the\_title() to the $title parameter, which you can then change any way you wish, but in the below case will change every title to say "Custom Title":
```
add_filter( 'my_filter_name', 'my_custom_function' );
function my_custom_function( $title ) {
return 'Custom Title';
}
```

What is the correct way of doing this in the event the plugin hasn't been enabled?
Should a check be made in every file where it's used within the theme directory to see if the class exists? Or should the error just be left as is and the user will know they have to enable the plugin based on the function name?

It's actually pretty simple to change the title in content-product.php, but you won't be able to do it with a hook. Near the top of the file, you should see this line:
```
Override this template by copying it to yourtheme/woocommerce/content-product.php
```

```
In order to change the title with a hook, you'd need to change the above line to this, but you can't do this without changing the wc-template-functions.php file. So what you can do is comment out the action in the content-product.php file:
```
//do_action( 'woocommerce_shop_loop_item_title' );
```
and then add the below line:
```
?><h3><?php echo apply_filters( 'my_filter_name', get_the_title() ); ?></h3><?php
```
so the saved version looks like this:
```
//do_action( 'woocommerce_shop_loop_item_title' );
?><h3><?php echo apply_filters( 'my_filter_name', get_the_title() ); ?></h3><?php
```
Then, you would need to add the following to your theme's functions.php file which will pass the contents of get\_the\_title() to the $title parameter, which you can then change any way you wish, but in the below case will change every title to say "Custom Title":
```
add_filter( 'my_filter_name', 'my_custom_function' );

<p>I've been trying around a lot to get this working, however every method I tried just didn't want to do as I wanted it to. So here I am.</p>
<p>I have a login-Mask that's only visible if the user is not logged in but it's permanently visible and covers some important areas. So here's my idea: hide it via toggle.</p>
<p>I know it's gonna take HTML, CSS and Javascript, so let's do this.</p>
<p>Here's a visual representation of where I'm at:
<a href="https://i.stack.imgur.com/WtGk6.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/WtGk6.jpg" alt="the framework"></a></p>
<p>Now I want the <strong>Login-Widget to only show AFTER you click the "Login" text</strong> up top.</p>
<ol>
<li>Div is hidden by default - CSS: display:none;</li>
<li>Text is <code><a></code>-Element with <code>href="#"</code></li>
</ol>
<p>So if you click the Text "Login", the Login-Mask appears and if you click it again, it disappears. Just normal toggle.</p>
<p>I guess the best idea is to use <code>div.toggleClass("open")</code> or something similar.</p>
<p><strong>Any help is appreciated!</strong></p>
<p><strong>edit01:</strong>
Here's my idea: functions.php</p>
<pre><code><script>
$( "a.toggle").click(function() {
$("div.log_forms").toggleClass( "open" );
});
</script>
</code></pre>
<p><strong>edit02:</strong></p>
<ol>
<li>jQuery is implemented as seen here
<a href="https://i.stack.imgur.com/uasY4.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/uasY4.png" alt="jQuery, check"></a></li>
<li>The site is loading JavaScript as seen in the other lines in the head-section</li>
<li>The code is correct as I've had it work on another site before (tried both # and .)</li>
<li>Heck, the script even gets loaded, as seen here

I've been trying around a lot to get this working, however every method I tried just didn't want to do as I wanted it to. So here I am.
I have a login-Mask that's only visible if the user is not logged in but it's permanently visible and covers some important areas. So here's my idea: hide it via toggle.
I know it's gonna take HTML, CSS and Javascript, so let's do this.
Here's a visual representation of where I'm at:
[](https://i.stack.imgur.com/WtGk6.jpg)
Now I want the **Login-Widget to only show AFTER you click the "Login" text** up top.
1. Div is hidden by default - CSS: display:none;
2. Text is `<a>`-Element with `href="#"`
So if you click the Text "Login", the Login-Mask appears and if you click it again, it disappears. Just normal toggle.
I guess the best idea is to use `div.toggleClass("open")` or something similar.
**Any help is appreciated!**
**edit01:**
Here's my idea: functions.php
```
<script>
$( "a.toggle").click(function() {
$("div.log_forms").toggleClass( "open" );
});
</script>
```
**edit02:**
1. jQuery is implemented as seen here
[](https://i.stack.imgur.com/uasY4.png)
2. The site is loading JavaScript as seen in the other lines in the head-section
3. The code is correct as I've had it work on another site before (tried both # and .)
4. Heck, the script even gets loaded, as seen here

You are calling jQuery wrong by the shorthand `$`. If you will look in your console you will see an error that `$` is not a function / undeclared etc (this is due to jQuery's conflict mode if I am not wrong).
Your code should look something like this:
```
<script type="text/javascript">
jQuery(function($) {
$( "a.toggle").click(function() {
$("#log_forms").toggleClass( "open" );
});
});
</script>
```

<p>I'm trying to make a query for users using <code>WP_User_Query()</code>
I need to filter users by role <code>shop_manager</code> and custom taxonomy called <code>shop-category</code> and current taxonomy term ID.</p>
<p>The code I have so far:</p>
<pre><code><?php
// WP_User_Query arguments
$args = array (
'role' => 'shop_manager',
'order' => 'DESC',
'orderby' => 'user_registered',
'tax_query' => array(
array('taxonomy' =>
'shop-category',
'field' => 'id',
'terms' => $term_id ) )
);
// The User Query
$user_query = new WP_User_Query( $args );
// The User Loop
if ( ! empty( $user_query->results ) ) {
foreach ( $user_query->results as $user ) {
echo '<li><span>' . esc_html( $user->shop_name ) . '</span></li>';
}
} else {
// no users found
}
?>
</code></pre>
<p>To get term ID I was using this code</p>
<pre><code><?php $queried_object = get_queried_object();
$term_id = $queried_object->term_id;
echo 'ID = '. $term_id;?>
</code></pre>
<p>Now it's showing all users with <code>shop_manager</code> role. Looks like taxonomy doesn't work.</p>

Apparently there is no core implementation of `'tax_query'` in `WP_User_Query` yet.
Check the ticket here for more info --> <https://core.trac.wordpress.org/ticket/31383>
Nevertheless there is an alternative way using `get_objects_in_term`
```
$taxonomy = 'shop-category';
$users = get_objects_in_term( $term_id, $taxonomy );
if(!empty($users)){
// WP_User_Query arguments
$args = array (

$user_query = new WP_User_Query( $args );

foreach ( $user_query->results as $user ) {
echo '<li><span>' . esc_html( $user->shop_name ) . '</span></li>';
}
}
else {
// no shop_manager found
}
}
else {
// no users found

You can set the `rewrite` `slug` when you [register your post type](https://codex.wordpress.org/Function_Reference/register_post_type):
```
$args = array(
'rewrite' => array( 'slug' => 'media/lajmet' )
// other args...
);

<p>I have a wierd problem.
If I inspect my WP pages using chrome element inspector I see two body tags thus:</p>
<pre><code><body cz-shortcut-listen="true">
<body>
</code></pre>
<p>This bit is to do with colorzilla (cz-shortcut-listen="true") in firebug it disappears. you have just 2 body tags with no classes.</p>
<p>The issue is not about the cz-shortcut-listen="true" bit coming from colorzilla. It is about the extra tag.</p>
<p>This duplication is causing styling and JS problems.
If I view source then just a single </p>
<pre><code><body>
</code></pre>
<p>is displayed with no classes.</p>
<p>No classes from body_class() are displayed in either view but I can echo them out into the source quite happily when they are not within this line in header.php </p>
<pre><code> <body <?php body_class();?>>
</code></pre>
<p>simply adding</p>
<pre><code><?php body_class();?>
</code></pre>
<p>above or below the line that renders the body tag displays all the body classes quite happily so they are being set.</p>
<p>If I comment out the line that renders the body tag in header.php using php commenting this body tag is still rendered </p>
<pre><code><body cz-shortcut-listen="true">
</code></pre>
<p>This happens with all themes and also to users outside of my local network and in chrome AND firefox so it seems not to be a theme or local browser issue. (See also UPDATE 2 below)</p>
<p>Has anyone any idea what it might be, it is a major headache and I'm quite stumped as to what it could be or how to even go about working out what the problem is.</p>

<p><strong>UPDATE 4</strong>
As per the answer below the issue does lies in the strange character present in the body tag however, deleting and replacing this line doesn't work.
The only thing that seems to work is surrounding the first line in html comments and having an identical uncommented line below, thus:</p>
<pre><code><!--<body <?php body_class(); ?>>-->

<p>If I remove the top commented line then the error re-occurs on the newly typed body tag.<br>
If I remove the body tag from the commented line but still have an empty comment thus:</p>

<p>Or I include the body_class function in the comment thus:</p>
<pre><code><!--<?php body_class(); ?>-->
<body <?php body_class(); ?>>-->
</code></pre>
<p>The behaviour reappears so the first body tag (even though commented) has to be present for the new one to render properly.</p>

This happens with all themes and also to users outside of my local network and in chrome AND firefox so it seems not to be a theme or local browser issue. (See also UPDATE 2 below)
Has anyone any idea what it might be, it is a major headache and I'm quite stumped as to what it could be or how to even go about working out what the problem is.

```
The behaviour reappears so the first body tag (even though commented) has to be present for the new one to render properly.
I have checked the Apache and php utf-8 encodings are in place. I checked in the browser that the page was seen as utf8 which it is. On the server
```
file -bi header.php
```
displays the file as ascii.
This gets wierder and wierder, I have a hack to get things working but not an understanding of what is happening.
Any thoughts on how to debug this would be very very gratefully received.

SOLUTION: see below. I added a separate answer for clarity.

I think this is the browser modifying the DOM due to a weird character you have in your body tag. When I view source in Firefox, I'm seeing the "character not recognized" box next to the body tag. This is also visible in Firefox inspector.
Modern browsers automatically fix issues in your HTML for you when rendering the page. For example, if you have a `<table>` without a `<tbody>`, the browser will add the `<tbody>` section for you, even though it isn't in your markup. What I think is happening here is that the browser is seeing a tag that is `<bodyX>` where `X` is a bad unicode character, and it's not recognizing it as a body tag, so it wraps the remainder of the content in a proper body tag, causing the duplication. This explains why it is not visible in view source (because view source is the literal source, not the modified source, which is visible in the inspector) and wget would produce the same behavior.
Try going into your theme's head file and deleting the body tag, then re-typing it, to remove any strange additional characters.
If that doesn't work, it is possible that there is something on the server that is incorrectly modifying the content of the body tag on the way out.

<p>I am looking to echo the most recent post in the loop of content. Only 1 post.</p>
<p>Do I need to put some sort of parameter on the following code:</p>

<p>Is there any way to style the message delivered by wp_debug?</p>
<p>Whenever I set WP_Debug to true, it pushes all my content down the page. While I admit it's easy to just set it back to false after using it, it can be somewhat tedious switching it on and off when it's needed.</p>
<p>Is there a way to style the message it creates, so that I'm then able to prevent it from moving content around?</p>

You could add following code (if not done already) in `wp-config.php` (please make a backup first of this file):
```
define('WP_DEBUG', true);
define( 'WP_DEBUG_LOG', true );
define( 'WP_DEBUG_DISPLAY', false );
```
This way `debug` is activated but the results (if have errors/notices) will not be shown but will be saved in a `logfile` which you can find then in `wp-content` folder. THe file which 'collects' all is `debug.log`.

Order by the last word in the post title
----------------------------------------
To order by the *speaker's last name*, you can use the following setup (PHP 5.4+):
```
// args
$args = [
'posts_per_page' => 10,
'post_type' => 'speaker',
'meta_key' => 'speaker-front-page',
'meta_value' => '1',
'orderby' => 'wpse_last_word', //<-- Our custom ordering!
'order' => 'ASC'
];
// query
$the_query = new WP_Query( $args );
```
where the `'wpse_last_word'` input is supported by the following:
```
/**
* Order posts by the last word in the post_title.
* Activated when orderby is 'wpse_last_word'
* @link https://wordpress.stackexchange.com/a/198624/26350
*/
add_filter( 'posts_orderby', function( $orderby, \WP_Query $q )
{
if( 'wpse_last_word' === $q->get( 'orderby' ) && $get_order = $q->get( 'order' ) )
{
if( in_array( strtoupper( $get_order ), ['ASC', 'DESC'] ) )
{
global $wpdb;
$orderby = " SUBSTRING_INDEX( {$wpdb->posts}.post_title, ' ', -1 ) " . $get_order;
}
}
return $orderby;
}, PHP_INT_MAX, 2 );
```
This is based on [my answer here](https://wordpress.stackexchange.com/questions/195034/taxonomy-terms-sort-by-last-name/195039#195039) on ordering terms by the last word.

I tried to add arrow down when the menu has a sub-menus. But the down arrow not showing up. Please help me.
Here's the link: <http://bit.ly/1UH4FlT>
Currently using this script that I found somewhere.
```
function add_menu_parent_class( $items ) {
$parents = array();
foreach ( $items as $item ) {
if ( $item->current_page_ancestor && $item-> current_page_ancestor> 0 ) {
$parents[] = $item->current_page_ancestor;
}
}
foreach ( $items as $item ) {
if ( in_array( $item->ID, $parents ) ) {
$item->classes[] = 'menu-item-has-children';
}
}
return $items;
}
add_filter( 'wp_nav_menu_objects', 'add_menu_parent_class' );
```
And I added this css
```
#site-navigation .menu > ul > li.menu-item-has-children > a:before {
color: #fff;
content: "\f107";
font-family:FontAwesome;
font-size: 10px;
vertical-align: 1px;
}
#site-navigation .menu > ul > li > li.menu-item-has-children > a:after {
color: #222;
content: ""\f105"";
font-family:FontAwesome;
font-size: 10px;
vertical-align: 1px;
}
```
|
Add below code
```
#site-navigation .menu > ul > li.menu-item-has-children > a::after {
content: '\f107';
font-family: FontAwesome;
font-size: 10px;
margin-left: 10px;
vertical-align: 1px;
}
#site-navigation .menu > ul > li > ul > li.menu-item-has-children > a::after {
color: rgb(34, 34, 34);
content: '\f105';
font-family: FontAwesome;

<p>I have a very simple WordPress plugin that shows a menu/admin page. The page contains Glyphicons - Font Awesome.</p>
<p>These glyphicons are never showing. I cannot figure out why because I know the font-awesome css file is being loaded correctly and I know that the admin pages HTML works fine outside of a wordpress plugin and shows the Glyphs.</p>
<p>What could possibly be going wrong?</p>

I want to automate updating plugin options. There are some things that I repeat a lot.
With [wp-cli](http://wp-cli.org) I know I can update simple options like this:
```
php wp-cli.phar option update blog_public 1
```
However, some plugin options save their options in a serialized string.
Example of serialized option\_value in wp\_options:
```
a:9:{s:4:"from";s:21:"[email protected]";s:8:"fromname";s:51:"xxx";s:4:"host";s:13:"smtp.xx.com";s:10:"smtpsecure";s:3:"ssl";s:4:"port";s:3:"465";s:8:"smtpauth";s:3:"yes";s:8:"username";s:21:"[email protected]";s:8:"password";s:13:"xxx";s:10:"deactivate";s:0:"";}
```
How to update those options?

WP-CLI is definitely the answer to this after the update to 1.4.0 which introduced the [pluck](https://developer.wordpress.org/cli/commands/option/pluck/) and [patch](https://developer.wordpress.org/cli/commands/option/patch/) commands for accessing serialized data in WordPress.
The pluck command takes this format for grabbing serialized values
```
wp option pluck <key> <key-name>
```
For example in the active\_plugins option you can grab first item
```
wp option pluck active_plugins 0
```
The patch command takes this format for inserting, updating or removing serialized values (the action)
```
wp option patch <action> <key> <key-name> <value>
```
Deleting the first active\_plugin would look like this
```
wp option patch delete active_plugins 0
```
The same pluck and patch were also added for other commands like postmeta, you can now use WP-CLI to do some cool loops for updating [WordPress serialized data programmatically](https://guides.wp-bullet.com/using-wp-cli-for-batch-updating-contact-form-7-postmeta-options/)

<p>I am trying to confirm if a filter I have applied has changed the wp_login_url to the correct address. I just want to print out the result of wp_login_url somewhere I can see it.</p>
<pre><code>if ( has_shortcode( $post->post_content, 'clean-login' ) ) {
add_filter('login_url', get_permalink( $post->ID ), 10, 2);
//$log_url = wp_login_url();
error_log(esc_url(wp_login_url($redirect)));
}
</code></pre>
<p>I have been playing round with printf echo and now error_log. Not a super experienced php guy and only just playing with the wp debug.log now. </p>
<p>Any help would be really appreciated.</p>

Note, the subcommand <a href=\"http://wp-cli.org/commands/option/get/\" rel=\"nofollow\"><code>get</code></a> should return you the option unserialized, because the Options API is used, which you then can save, modify and/or transfer/set-up on other/new installations.</p>\n"

I am trying to confirm if a filter I have applied has changed the wp\_login\_url to the correct address. I just want to print out the result of wp\_login\_url somewhere I can see it.
```
if ( has_shortcode( $post->post_content, 'clean-login' ) ) {
add_filter('login_url', get_permalink( $post->ID ), 10, 2);
//$log_url = wp_login_url();
error_log(esc_url(wp_login_url($redirect)));
}
```
I have been playing round with printf echo and now error\_log. Not a super experienced php guy and only just playing with the wp debug.log now.
Any help would be really appreciated.

WP-CLI is definitely the answer to this after the update to 1.4.0 which introduced the [pluck](https://developer.wordpress.org/cli/commands/option/pluck/) and [patch](https://developer.wordpress.org/cli/commands/option/patch/) commands for accessing serialized data in WordPress.
The pluck command takes this format for grabbing serialized values
```
wp option pluck <key> <key-name>
```
For example in the active\_plugins option you can grab first item
```
wp option pluck active_plugins 0
```
The patch command takes this format for inserting, updating or removing serialized values (the action)
```
wp option patch <action> <key> <key-name> <value>
```
Deleting the first active\_plugin would look like this
```
wp option patch delete active_plugins 0
```
The same pluck and patch were also added for other commands like postmeta, you can now use WP-CLI to do some cool loops for updating [WordPress serialized data programmatically](https://guides.wp-bullet.com/using-wp-cli-for-batch-updating-contact-form-7-postmeta-options/)

You need to listen for the `click` event (there is no such thing as a pre/before click) and do some work right then or figure out if you want to allow the `click` to "go through" or not based on some validation for example.
```
jQuery(function($) {
// We are binding to the body so that the code
// will work for future elements added to the DOM
$('body').on('click', '.widget-control-save', function(ev) {
var my_validation = true;
if ( my_validation ) {
console.log('widget save!');
} else {
ev.preventDefault();
ev.stopPropagation(); /* We are capturing the event so it won't bubble up. */
}
})
});
```

<p>So I have been reading through every WordPress front-end AJAX file upload tutorial I can fine. Nothing is working for me at the moment. The one that makes the most sense to me is this one: <a href="http://theaveragedev.com/wordpress-files-ajax/" rel="noreferrer">http://theaveragedev.com/wordpress-files-ajax/</a></p>
<p>Here is my code:</p>
<p>In my template file example.php</p>
<pre><code><script>var ajax_url = "<?php echo admin_url('admin-ajax.php'); ?>"</script>
<form id="file_form">
<?php wp_nonce_field('ajax_file_nonce', 'security'); ?>
<input type="hidden" name="action" value="my_file_upload">
<label for="file_upload">It's a file upload...</label>
<input type="file" name="file_upload">
<input type="submit" value="Go">
</form>
</code></pre>
<p>This is in ajax-file-upload.js</p>
<pre><code>jQuery(document).ready(function(){
var form_data = {};
$(this).find('input').each(function(){
form_data[this.name] = $(this).val();
});
$('#file_form').ajaxForm({
url: ajax_url, // there on the admin side, do-it-yourself on the front-end
data: form_data,
type: 'POST',
contentType: 'json',
success: function(response){
alert(response.message);
}
});
});
</code></pre>
<p>This is in my functions.php</p>
<pre><code>function q_scripts(){
$src = get_template_directory_uri().'/js/ajax-file-upload.js';
wp_enqueue_script('my_ajax_file_uploader_thing', $src, array('jquery', 'jquery-form'));
}
add_action('init', 'q_scripts');
function handle_file_upload(){
check_ajax_referer('ajax_file_nonce', 'security');
if(!(is_array($_POST) && is_array($_FILES) && defined('DOING_AJAX') && DOING_AJAX)){
return;
}
if(!function_exists('wp_handle_upload')){
require_once(ABSPATH . 'wp-admin/includes/file.php');
}
$upload_overrides = array('test_form' => false);
$response = array();
foreach($_FILES as $file){
$file_info = wp_handle_upload($file, $upload_overrides);
// do something with the file info...
$response['message'] = 'Done!';
}
echo json_encode($response);
die();
}
add_action('wp_ajax_my_file_upload', 'handle_file_upload');
</code></pre>
<p>I have tried adding the enctype to the form element and this didn't work. The error I keep getting is an alert saying 'undefined'. Does anyone know how I can correct this issue?</p>
<p><strong>EDIT</strong></p>
<p>The 'undefined' issue has now gone away as I editied the js file to have a click event and changed the selector for the form input loop:</p>
<pre><code>jQuery(document).ready(function($){
$('#file_form :submit').click(function() {
var form_data = {};
$('#file_form').find('input').each(function () {
form_data[this.name] = $(this).val();
});
console.log(form_data);
$('#file_form').ajaxForm({
url: ajax_url, // there on the admin side, do-it-yourself on the front-end
data: form_data,
type: 'POST',
contentType: 'json',
success: function (response) {
alert(response.message);
},
error: function (response) {
console.log('error');
}
});
return false;
});
});
</code></pre>
<p>The files still aren't being uploaded to the media folder. I also want to get the uploaded URL back once it has uploaded.</p>
<p>I am writing to the console the file object so I can see what is happening. Here is an example of it:</p>
<pre><code>Object {security: "e6db2a6eee", _wp_http_referer: "/chat?sessionappid=138", action: "my_file_upload", file_upload: "C:\fakepath\download.jpg", "": "Go"}
</code></pre>
<p>Is there something wrong with this and is that why it isn't uploading?</p>

In my template file example.php
```
<script>var ajax_url = "<?php echo admin_url('admin-ajax.php'); ?>"</script>
<form id="file_form">
<?php wp_nonce_field('ajax_file_nonce', 'security'); ?>
<input type="hidden" name="action" value="my_file_upload">
<label for="file_upload">It's a file upload...</label>
<input type="file" name="file_upload">
<input type="submit" value="Go">
</form>
```
This is in ajax-file-upload.js
```
jQuery(document).ready(function(){
var form_data = {};
$(this).find('input').each(function(){
form_data[this.name] = $(this).val();
});
$('#file_form').ajaxForm({
url: ajax_url, // there on the admin side, do-it-yourself on the front-end
data: form_data,
type: 'POST',
contentType: 'json',
success: function(response){
alert(response.message);
}
});
});
```
This is in my functions.php
```
function q_scripts(){
$src = get_template_directory_uri().'/js/ajax-file-upload.js';
wp_enqueue_script('my_ajax_file_uploader_thing', $src, array('jquery', 'jquery-form'));
}
add_action('init', 'q_scripts');
function handle_file_upload(){
check_ajax_referer('ajax_file_nonce', 'security');
if(!(is_array($_POST) && is_array($_FILES) && defined('DOING_AJAX') && DOING_AJAX)){
return;
}
if(!function_exists('wp_handle_upload')){
require_once(ABSPATH . 'wp-admin/includes/file.php');
}
$upload_overrides = array('test_form' => false);
$response = array();
foreach($_FILES as $file){
$file_info = wp_handle_upload($file, $upload_overrides);
// do something with the file info...
$response['message'] = 'Done!';
}
echo json_encode($response);
die();
}
add_action('wp_ajax_my_file_upload', 'handle_file_upload');
```
I have tried adding the enctype to the form element and this didn't work. The error I keep getting is an alert saying 'undefined'. Does anyone know how I can correct this issue?
**EDIT**
The 'undefined' issue has now gone away as I editied the js file to have a click event and changed the selector for the form input loop:
```
jQuery(document).ready(function($){
$('#file_form :submit').click(function() {
var form_data = {};
$('#file_form').find('input').each(function () {
form_data[this.name] = $(this).val();
});
console.log(form_data);
$('#file_form').ajaxForm({
url: ajax_url, // there on the admin side, do-it-yourself on the front-end
data: form_data,
type: 'POST',
contentType: 'json',
success: function (response) {
alert(response.message);
},
error: function (response) {
console.log('error');
}
});
return false;
});
});
```
The files still aren't being uploaded to the media folder. I also want to get the uploaded URL back once it has uploaded.
I am writing to the console the file object so I can see what is happening. Here is an example of it:
```
Object {security: "e6db2a6eee", _wp_http_referer: "/chat?sessionappid=138", action: "my_file_upload", file_upload: "C:\fakepath\download.jpg", "": "Go"}
```
Is there something wrong with this and is that why it isn't uploading?

Hi You have Use this COde For WordPress front-end AJAX file upload tutorial Code
Here is my code:
In my template file example.php
```
<form enctype="multipart/form-data">
<input type="text" name="support_title" class="support-title">
<input type="file" id="sortpicture" name="upload">
<input class="save-support" name="save_support" type="button" value="Save">
</form>
```
This is in ajax-file-upload.js
```
jQuery(document).on('click', '.save-support', function (e) {
var supporttitle = jQuery('.support-title').val();
var querytype = jQuery('.support-query').val();
var file_data = jQuery('#sortpicture').prop('files')[0];
var form_data = new FormData();
if (supporttitle == '') {
jQuery('.support-title').css({"border": "1px solid red"})
return false;
} else {
jQuery('.support-title').css({"border": "1px solid #e3ecf0"})
}
form_data.append('file', file_data);
form_data.append('action', 'md_support_save');
form_data.append('supporttitle', supporttitle);
jQuery.ajax({
url: '<?php echo admin_url('admin-ajax.php'); ?>',
type: 'post',
contentType: false,
processData: false,
data: form_data,
success: function (response) {
jQuery('.Success-div').html("Form Submit Successfully")
},
error: function (response) {
console.log('error');
}
});
});
});
```
This iS functions.php code
```
add_action( 'wp_ajax_md_support_save','md_support_save' );
add_action( 'wp_ajax_nopriv_md_support_save','md_support_save' );
function md_support_save(){
$support_title = !empty($_POST['supporttitle']) ?
$_POST['supporttitle'] : 'Support Title';
if (!function_exists('wp_handle_upload')) {
require_once(ABSPATH . 'wp-admin/includes/file.php');
}
// echo $_FILES["upload"]["name"];
$uploadedfile = $_FILES['file'];
$upload_overrides = array('test_form' => false);
$movefile = wp_handle_upload($uploadedfile, $upload_overrides);

I am trying to limit the files that are shown in the wordpress media library popup (from wp\_editor).
*Currently every single file that I have ever uploaded to my site is shown in the library but I would like to limit what users see to just files uploaded in the last 24 hours.*
It is possible to limit the media library by author using the following code; however I'm not even sure where to start to limit the media library popup to files uploaded in the last 24 hours.
```
add_action('pre_get_posts','users_own_attachments');
function users_own_attachments( $wp_query_obj ) {
global $current_user, $pagenow;
if( !is_a( $current_user, 'WP_User') )
return;
if( !in_array( $pagenow, array( 'upload.php', 'admin-ajax.php' ) )
return;
if( !current_user_can('delete_pages') )
$wp_query_obj->set('author', $current_user->ID );
return;
}
```
|
You can adjust the *attachment query* in the media library popup, through the `ajax_query_attachments_args` filter.
Here are two PHP 5.4+ examples:
**Example #1:**
Show only attachments that where uploaded during the last 24 hours:
```
/**
* Media Library popup
* - Only display attachments uploaded during the last 24 hours:
*/
add_filter( 'ajax_query_attachments_args', function( $args )
{
$args['date_query'] = [['after' => '24 hours ago', 'inclusive' => true ]];
return $args;
} );
```
**Example #2:**
Show only attachments that where uploaded during the last 24 hours by the current user:
```
/**
* Media Library popup
* - Only display attachments uploaded during the last 24 hours by the current user:
*/
add_filter( 'ajax_query_attachments_args', function( $args )
{
$args['author'] = get_current_user_id();
$args['date_query'] = [['after' => '24 hours ago', 'inclusive' => true ]];
return $args;
} );
```

I am trying to create custom menu nav walker. I added below code
```
function display_element( $element, &$children_elements, $max_depth, $depth=0, $args, &$output )
{
$id_field = $this->db_fields['id'];

}
return parent::display_element( $element, $children_elements, $max_depth, $depth, $args, $output );
}

I have the same issue. Some answers claim that you can use `$args->has_children` or `$args[0]->has_children`, but it's never added to $args. Sometimes, `has_children` is added under `$args->walker->has_children`, but it's always set to `false`, in other words, useless...
As a work around, the current template that I'm using adds a class to items that contain children (menu-item-has-children), so I searched for it under `$item->classes`.
```
function end_el( &$output, $item, $depth = 0, $args = array() ) {
if( !empty($item->classes) &&
is_array($item->classes) &&
in_array('menu-item-has-children', $item->classes) ){
// This guy has children
}
}
```
I guess, you could add a mark in your start\_el function and then search for it...
I hope this helps. If you have a better solutions, please share it.

You may not have configured Apache. Add this line in your `apache2.conf` file:
```
AddType application/x-httpd-php .php .htm .html
```
Evidently, you should make sure you actually have [installed and activated the PHP module](http://php.net/manual/en/install.unix.debian.php) first and foremost (the above Apache directive might not even be necessary in this case). In this regard, you can visit the `/etc/apache2/mods-enabled/` folder and look for the `php5.load`, `php5.conf` files.

<p>After my WordPress site was updated to 4.2.4, my PayPal buttons no longer work. I can SEE the buttons, but can't click on them and go to PayPal. Hovering over the button shows no web link. I've recopied the code from PayPal several times, to no avail. </p>
<p>I notice that the (form) command gets screwed up every time I save/update the page where the buttons are. It puts the (/form) BEFORE the table where I have price options, near the beginning of the code. I then cut it and put it at the END of the code, click "update" and when I go back into the text mode, it has moved the again! Very frustrating. </p>
<p>I posted this question on WordPress.org, but no answers as of yet. I also emailed PayPal, but no answers yet either. Any ideas?</p>
<h2>Thanks</h2>
<p><strong>UPDATE</strong>: I see that when I put the (form) command, it stripped it because it was HTML. So I've put parentheses on it now so it shows up.
The page on my website where I'm having the problem is:
<a href="http://sonomabodybalance.com/workshops/" rel="nofollow">www.sonomabodybalance.com/workshops/</a></p>
<p>You can see the PayPal button, but hovering or clicking does nothing.</p>
<p>I've pasted the CODE here, and I indented by 4 spaces, like the "How to Format" instructions say, but it's not working: (suggestions welcome...)

After my WordPress site was updated to 4.2.4, my PayPal buttons no longer work. I can SEE the buttons, but can't click on them and go to PayPal. Hovering over the button shows no web link. I've recopied the code from PayPal several times, to no avail.
I notice that the (form) command gets screwed up every time I save/update the page where the buttons are. It puts the (/form) BEFORE the table where I have price options, near the beginning of the code. I then cut it and put it at the END of the code, click "update" and when I go back into the text mode, it has moved the again! Very frustrating.
I posted this question on WordPress.org, but no answers as of yet. I also emailed PayPal, but no answers yet either. Any ideas?
Thanks
------
**UPDATE**: I see that when I put the (form) command, it stripped it because it was HTML. So I've put parentheses on it now so it shows up.
The page on my website where I'm having the problem is:
[www.sonomabodybalance.com/workshops/](http://sonomabodybalance.com/workshops/)
You can see the PayPal button, but hovering or clicking does nothing.
I've pasted the CODE here, and I indented by 4 spaces, like the "How to Format" instructions say, but it's not working: (suggestions welcome...)

You may not have configured Apache. Add this line in your `apache2.conf` file:
```
AddType application/x-httpd-php .php .htm .html
```
Evidently, you should make sure you actually have [installed and activated the PHP module](http://php.net/manual/en/install.unix.debian.php) first and foremost (the above Apache directive might not even be necessary in this case). In this regard, you can visit the `/etc/apache2/mods-enabled/` folder and look for the `php5.load`, `php5.conf` files.

WordPress already has a default URL for jQuery-WordPress application calls and it's well known as the `ajaxurl`. However, there are cases wherein one would need to enable **Cross-Origin Resource Sharing** (CORS) on it such that any hostname will be able to access using it.
My current solutions is by adding a line in `/wp-includes/http.php` with:
```
@header( 'Access-Control-Allow-Origin: *' );
```
Such that it will be:
http.php
--------
```
...

It works but editing the WordPress core is not a good solution.
Is there a better way to enable CORS for the `ajaxurl`?

Milo is correct.
For instance, go to your theme's functions.php file, and add the following:
```
add_filter( 'allowed_http_origins', 'add_allowed_origins' );
function add_allowed_origins( $origins ) {
$origins[] = 'https://site1.example.com';
$origins[] = 'https://site2.example.com';
return $origins;
}
```
Now an ajax call from <https://site1.example.com> to your site's ajax url will have the appropriate Access-Control-Allow-Origin header in the response. eg.
```
$.ajax({
url: 'https://site1.example.com/wp-admin/admin-ajax.php',
type: "POST",
data: {
...
},
success: function(doc) {
...
}
});
```

I've dumped all hooks using [this](http://www.rarst.net/wordpress/debug-wordpress-hooks/) (one logged in with subscriber, one with admin), but I find no considerable difference. [Case A](http://https://gist.githubusercontent.com/Thefirsh/3175b3aab22d3edb61ee/raw/197dfcf21f563ff10704f7e73f3ee00ef5407c6b/a.txt) / [Case B](https://gist.githubusercontent.com/Thefirsh/3175b3aab22d3edb61ee/raw/197dfcf21f563ff10704f7e73f3ee00ef5407c6b/b.txt).

Milo is correct.
For instance, go to your theme's functions.php file, and add the following:
```
add_filter( 'allowed_http_origins', 'add_allowed_origins' );
function add_allowed_origins( $origins ) {
$origins[] = 'https://site1.example.com';
$origins[] = 'https://site2.example.com';
return $origins;
}
```
Now an ajax call from <https://site1.example.com> to your site's ajax url will have the appropriate Access-Control-Allow-Origin header in the response. eg.
```
$.ajax({
url: 'https://site1.example.com/wp-admin/admin-ajax.php',
type: "POST",
data: {
...
},
success: function(doc) {
...
}
});
```

If you just want to list them you can use the get\_terms function:
```
$terms = get_terms( 'my_taxonomy' );
if ( ! empty( $terms ) && ! is_wp_error( $terms ) ){
echo '<ul>';
foreach ( $terms as $term ) {
echo '<li>' . $term->name . '</li>';
}

Read the codex, it has a lot of examples:

<p>I'm trying to return a custom field as soon as a post gets published. I'm using the <code>publish_post</code> (or <code>{status}_{post_type}</code>) action, but it looks like the custom fields are created after the hook.</p>
<p>My code in <code>functions.php</code>:</p>
<pre><code>function create_recurring_posts( $ID, $post ) {
logMe(print_r(get_post_custom($ID), true));
}
add_action( 'publish_profile', 'create_recurring_posts', 10, 2 );
</code></pre>
<p>The <code>logMe()</code> function just logs the output to a file for testing purposes. My problem is, when I create the profile post, the only custom fields that get returned are <code>_edit_last</code> and <code>_edit_lock</code>. But when I view the page afterwards, where I have the same <code>get_post_custom()</code> function being ran, I see the other custom field I need.</p>
<p>I'm using Advanced Custom Fields for the field creation. Any help is appreciated.</p>

I'm trying to return a custom field as soon as a post gets published. I'm using the `publish_post` (or `{status}_{post_type}`) action, but it looks like the custom fields are created after the hook.
My code in `functions.php`:
```
function create_recurring_posts( $ID, $post ) {
logMe(print_r(get_post_custom($ID), true));
}
add_action( 'publish_profile', 'create_recurring_posts', 10, 2 );
```
The `logMe()` function just logs the output to a file for testing purposes. My problem is, when I create the profile post, the only custom fields that get returned are `_edit_last` and `_edit_lock`. But when I view the page afterwards, where I have the same `get_post_custom()` function being ran, I see the other custom field I need.
I'm using Advanced Custom Fields for the field creation. Any help is appreciated.

Your action is triggered in `wp_transition_post_status()` which gets called by `wp_insert_post()` *before* the action `save_post` is triggered. `save_post` is the typical action to handle custom fields. ACF also works on this.
Basically you have to wait until ACF is done with its stuff, means you'll have to hook to `save_post` with a priority > 10 or better use `wp_insert_post` which runs right after `save_post`.
To track the post status transition, you can use a simple »log« like this:
```
<?php
namespace WPSE199070;
class PublishedTransitionLog {
/**
* @type array
*/
private $status_log = [];
/**
* logs a published post id
*
* @wp-hook publish_profile
*
* @param int $post_id
*/
public function published_post( $post_id ) {
$blog_id = get_current_blog_id();
if ( ! isset( $this->status_log[ $blog_id ] ) )
$this->status_log[ $blog_id ] = [];
if ( in_array( $post_id, $this->status_log[ $blog_id ] ) )
return;
$this->status_log[ $blog_id ][] = $post_id;
}
/**
* @param int $post_id
* @return bool
*/
public function post_published( $post_id ) {
$blog_id = get_current_blog_id();
if ( ! isset( $this->status_log[ $blog_id ] ) )
return FALSE;
return in_array( $post_id, $this->status_log[ $blog_id ] );
}
}
class PublishPostHandler {
/**
* @type PublishedTransitionLog
*/
private $log;
public function __construct( PublishedTransitionLog $log ) {
$this->log = $log;
}
/**
* @param int $post_id
* @param \WP_Post $post
* @param bool $updated
*/
public function update( $post_id, \WP_Post $post, $updated ) {
if ( ! $this->log->post_published( $post_id ) )
return;
// do your stuff here
}
}
$transition_log = new PublishedTransitionLog;
$handler = new PublisPostHandler( $transition_log );
add_action( 'publish_profile', array( $transition_log, 'published_post' ) );
add_action( 'wp_insert_post', array( $handler, 'update', 10, 3 ) );
```
Let me explain this. The first class, `PublishedTransitionLog` listens to the action `publish_profile` and stores each published post for each blog internally. It also provides a method to check if a post was published before.
The second class should provide your logic and depends on the first class. If the post was not published it does just nothing.
This way you can listen independently to tow different hooks.

<p>This error only happened this morning as I updated my wordpress site to version 4.3. Two other sites on the same hosting ( and all using CPanel as an admin portal for the hosting) are not having any problem. On this one problematic site company.com though on the wordpress admin portal and the live site there is an error repeating several times at the top of the page, that is:</p>
<p><a href="https://i.stack.imgur.com/OfHNk.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/OfHNk.png" alt="The error continues down the page like this 9 times."></a></p>
<p><a href="https://i.stack.imgur.com/X4nMM.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/X4nMM.png" alt="The error page is then finished off with this error/line."></a></p>
<p>I have read up today on this and it is perhaps to do with upgrading from PHP4 to PHP5, although there is no problem with the other WP sites on the same server. I also disabled all the plugins on the site to test and the problem was still there. Short of restoring from a backup (which is not easy to do and can cause errors of its own) is there anyone else having this issue today/recently? </p>
<p>It does not help that the error message appears to suggest a solution itself before it is cut off at the end with </p>
<blockquote>
<p>Use...". The error message begins "company/public_html/wp-includes/ ...". The second line is "constructor method for WP_Widget is deprecated since version 4.3.0. </p>
</blockquote>
<p>Version 4.3 is the version that WP was updated to today. It seemingly has caused this error but I do not know how to fix it. </p>
<p>Any other information needed to answer this I'll be more than happy to provide.</p>

The error isn't actually caused by your PHP version (PHP 4 constructors won't be removed until PHP 7) - it's a warning produced by WordPress in preparation for this. Each repetition of the error represents a plugin using the outdated code.
Until your plugins' authors update them, you can run the following shell command on a Linux system to find the old constructor calls:
```
grep -R "WP_Widget\(" /path/to/your/wp/install
```
This will give you a list of files that you can either modify on the command line, or use WP's plugin editor. Matched strings - mostly `parent::WP_Widget(args)` should be changed to `parent::__construct(args)`.

What is the best way to pass some information from `functions.php` to a plugin?
I need to give a user the ability to *pass* a piece of data *from* their `functions.php` file *to* my plugin. (It can be any data, just something that I can check for; it can be a variable's value, or even the fact that a variable was set or a function was defined.)
I tried the suggestion found here:
[Pass A Value From Outside To A Plugin Variable](https://wordpress.stackexchange.com/questions/169284/pass-a-value-from-outside-to-a-plugin-variable)
I plugged in that code verbatim:
*On your plugin :*
```
$value = 0;
$value = apply_filter('get_value_from_function', $value);
```
*Then on `functions.php`*
```
add_filter('get_value_from_function', 'my_special_value_treatment', 10, 1);
function my_special_value_treatment ($value){
return 1;
}
```
But that results in an error:
>
> Fatal error: Call to undefined function apply\_filter() in /pathtomyplugin/my-plugin-name/my-plugin-name.php on line 93
>
>
>
I don't understand why that fails. What is the best way to do this?
*Edited with this addition:*
After changing it to `apply_filters()`, this still happens... In my plugin:
```
$value = 0;
$value = apply_filters('get_value_from_function', $value);
if ($value===0) {
$test_info = 'not_passed';
} else {
$test_info = 'passed';
};
// $test_info is not_passed
```

Plugins are loaded before the theme which means that your `apply_filters` won't have any actual callbacks registered to it. Instead, you need to call your `apply_filters` sometime after the theme has been loaded. Something like this:
```
/* Your plugin's file: */
add_action( 'init', 'my_lovely_funky_filters' );
function my_lovely_funky_filters() {
/* Fire our callbacks */
$value = 0;
$value = apply_filters( 'get_value_from_function', $value );
/* Check your $value now */
/* echo "<pre>{$value}</pre>"; */
}
/* Your functions.php file */
add_filter( 'get_value_from_function', 'my_special_value_treatment', 10, 1 );
function my_special_value_treatment( $value ) {
/* A little more interesting */
return (int)$value + 1;

I have a custom post type that is an Event.
I'm trying to query those Events and only return Events that are in the current month or later. So the event could be in the past, but it has to be in the same month. The event date is a custom field.
So right now I would only want events that were in the month of August or later, and no events prior to August.
Here's my current query, ordered from oldest to newest:
```
$custom_post_type = 'event';
$args = array(
'post_type' => $custom_post_type,
'post_status' => 'publish',
'meta_key' => 'event_date_and_time',
'orderby' => 'meta_value_num',
'order' => 'ASC',
'posts_per_page' => -1
);
$events = get_posts($args);
```
|
You can use `meta_query`, if you date information is saved in custom field. Like this:
```
$args = array(
'post_type' => $custom_post_type,
'posts_per_page' => -1,
'meta_query' => array(
array(
'key' => 'event_date_and_time',
'value' => current_time('Ymd'),
'compare' => '>='
)
),
'orderby' => 'meta_value_num',
'order' => 'ASC'
);
```
This code suppose you date is saved in YYYYMMDD format (20150820). And it shows post from today to future, so you will have to change `value` to "first day of current month".

I have some problems to asign a class to tag with wp\_nav\_menu() instead of asign the class to the tag it creates a and asign the class to that one.
My register\_nav\_menu function:
```
function register_primary_menu() {
register_nav_menu('primary-menu', __('Primary Menu'));
}
add_action('init', 'register_primary_menu');
```
wp\_nav\_menu:
```
<?php
$defaults = array(
'theme_location' => 'primary-menu',
'menu' => '',
'container' => 'flase',
'container_class' => '',
'container_id' => '',
'menu_class' => 'nav navbar-nav',
'menu_id' => '',
'echo' => true,
'fallback_cb' => 'wp_page_menu',
'before' => '<li>',
'after' => '</li>',
'link_before' => '',
'link_after' => '',
'items_wrap' => '<ul id="%1$s" class="%2$s">%3$s</ul>',
'depth' => 0,
'walker' => ''
);
wp_nav_menu( $defaults );
?>
```
What I want is this:
```
<ul class="nav navbar-nav">
<li><a href="#">Home</a></li>
<li><a href="#">Page 1</a></li>
<li><a href="#">Page 2</a></li>
<li><a href="#">Page 3</a></li>
</ul>
```
And what I get is this:
```
<div class="nav navbar-nav">
<ul>
<li class="page_item page-item-56"><a href="[URL]">Page 1</a></li>
<li class="page_item page-item-58"><a href="[URL]">Page 2</a></li>
<li class="page_item page-item-60"><a href="[URL]">Page 3</a></li>
<li class="page_item page-item-2"><a href="[URL]">Sample Page</a></li>
</ul>
</div>
```

Make sure your menu does setup correctly in that location in Appearance / Menus, unless it wont display that class. After you set the theme location to Primary Menu, it should work fine. No idea why, guess its a bug in WordPress.
Also fix the typo: `'container' => false`

How do I query for a specific user role?
```
if (is_user_logged_in() && user_role == "user") {}
```
The part I'm unsure about is user\_role.
**Is there a way I can ask WordPress to check for a specific user role by name/string**?
|
You can check for specific user role using following code -
```
if (is_user_logged_in() && current_user_can('administrator')) {}
```
The function current\_user\_can() takes role name as parameter.

Im have a little issue querying a custom post type by category using the\_title();
The reason why im doing it like this is because the title is the same as the category name.
```
$args = array('post_type' => 'Testimonials', 'order' => 'ASC', 'category_name' =>the_title());
```
However with this im not getting a thing i have also tried this:
```
$title = the_title();
$args = array('post_type' => 'Testimonials', 'order' => 'ASC', 'category_name' =>$title);
```
Any help?

Look at the declaration of the function `the_title()`, it prints the title, if the third parameter `$echo` is set to `TRUE` which is the default:
```
/**
* Display or retrieve the current post title with optional content.
*
* @since 0.71
*
* @param string $before Optional. Content to prepend to the title.
* @param string $after Optional. Content to append to the title.
* @param bool $echo Optional, default to true.Whether to display or return.
* @return null|string Null on no title. String if $echo parameter is false.
*/
function the_title($before = '', $after = '', $echo = true) {
$title = get_the_title();
if ( strlen($title) == 0 )
return;
$title = $before . $title . $after;
if ( $echo )
echo $title;
else
return $title;
}
```
So either you use `the_title( '', '', FALSE )` or even better `get_the_title()` because it makes the code better readable:
```
$title = get_the_title();
$args = array(
'post_type' => 'Testimonials',
'order' => 'ASC',
'category_name' => $title
);
```

<p>I've a pretty basic problem that I'm surprised WP doesn't have a native solution for (unless I'm overlooking something, hopefully). </p>
<p>I've a WP site with <code>static page</code> set as front page in reading setting. In a plugin code, I'm trying to determine whether WP is displaying the front page and add a class to <code>$classes</code> array if so is true. I'm using following code to accomplish it </p>

```

```
I'm using both `is_front_page()` and `is_home()` in case the front page setting changes from static page to blog layout in future.
The issue I'm encountering is that this code adds `home-page` class to `body` even on `wp-signup.php` page.
Inspecting the code reveals that `is_front_page()` calls `WP_Query::is_front_page()` , which essentially returns results of `WP_Query::is_page(get_option('page_on_front'))`. So the root of the problem is that `wp-signup.php` qualifies as the page (id) returned by `get_option('page_on_front')` (*which returns `ID` of the static page set as front page in settings > reading*).
`WP_Query::is_page()` uses `WP_Query::get_queried_object()` internally to decide whether current page is the page present in method arguments. In `wp-signup.php` case, the code that sets the current queried object is as following
```
/*...other code... */

$this->queried_object = $this->post;
$this->queried_object_id = (int) $this->post->ID;
}
/*...other code... */
```
This shows that wordpress, for some reason, queries the front page in order to display `wp-signup.php` and raises following questions.
* Why `is_front_page()` is returning wrong results?
* AFAIK `wp-signup.php` can never be set as home page using Wordpress administrator setting then why wordpress code isn't bailing out just by checking `PHP_SELF` or `REQUEST_URI`?
* Why does WP\_Query have current home page in `$this->post` at this point?
I've ruled out *plugin issue* by removing the plugins (and mu-plugins) directory. It still qualifies `wp-signup.php` as front page where it doesn't for any other page.
Any help regarding this issue will be greatly appreciated.

Just speculation, but I wonder if you're running into an anonymous function problem. Anonymous functions are allowed in WP, and usually work fine (presuming updated PHP), but, if you search around you'll find reports of suspected bugs or at least of unexpected behavior.
For that matter, I'm not sure that I've ever seen an anonymous function used as an example in the WordPress Codex, and I can't recall ever running across one before in theme and plug-in code. Of course, I've not had my eye out for anon functions, but, still, I think the above function will almost always be written in some version of the more familiar two-part format - ie:
```
add_filter('body_class', 'ejay_add_home_class');
function ejay_add_home_class($classes) {
if (is_front_page() || is_home()) {
$classes[] = 'home-page';
}
return $classes;
}
```
So, as an experiment, I'd try the above more "conventional" format, and also try it with a designated priority higher or lower than 10. If attaching multiple anonymous functions to the same filter, I'd give them different priorities, or use an array (example here: <http://snippets.khromov.se/adding-multiple-actions-and-filters-using-anonymous-functions-in-wordpress/> ), or write each one of them as named two-parters, too.
In truth, I find the slightly lengthier 2-part way easier to read, track, and adjust anyway.

Just speculation, but I wonder if you're running into an anonymous function problem. Anonymous functions are allowed in WP, and usually work fine (presuming updated PHP), but, if you search around you'll find reports of suspected bugs or at least of unexpected behavior.
For that matter, I'm not sure that I've ever seen an anonymous function used as an example in the WordPress Codex, and I can't recall ever running across one before in theme and plug-in code. Of course, I've not had my eye out for anon functions, but, still, I think the above function will almost always be written in some version of the more familiar two-part format - ie:
```
add_filter('body_class', 'ejay_add_home_class');
function ejay_add_home_class($classes) {
if (is_front_page() || is_home()) {
$classes[] = 'home-page';
}
return $classes;
}
```
So, as an experiment, I'd try the above more "conventional" format, and also try it with a designated priority higher or lower than 10. If attaching multiple anonymous functions to the same filter, I'd give them different priorities, or use an array (example here: <http://snippets.khromov.se/adding-multiple-actions-and-filters-using-anonymous-functions-in-wordpress/> ), or write each one of them as named two-parters, too.
In truth, I find the slightly lengthier 2-part way easier to read, track, and adjust anyway.

I'm creating a template for archive-product.php page in WooCommerce.
I would like to have 3 boxes and link each to a different product category.
**How do I get dynamic link to each product category in `<a>` tag?**
For now I put static links, but I'm sure there is a way to make them dynamic in WordPress
Here's what my code looks like:
```
<ul class="shop-items">
<li class="fine-art">
<a href="http://url.com/product-category/categories/fine-art/">
<div>Fine Art
<span>Description</span>
</div>
</a>
</li>
<li class="dance-art">
<a href="http://url.com/product-category/categories/dance-art/">
<div>Dance Art
<span>Description</span>
</div>
</a>
</li>
<li class="history-art">
<a href="http://url.com/product-category/categories/history-art/">
<div>History Art
<span>Description</span>
</div>
</a>
</li>
</ul>
```

For this purpose there is `get_term_link` function ([documentation](https://codex.wordpress.org/Function_Reference/get_term_link)).
```
<a href="<?php echo get_term_link( 42 ,'product_cat') ?>">Fine Art ... etc.</a>
```
Product category is just WP taxonomy, so there is plenty of functions to work with. In this case you have to know your product category ID (taxonomy term ID, actually). When editing category, you will find it in URL: .../edit-tags.php?action=edit&taxonomy=product\_cat&tag\_ID=**42**&post\_type=product

This is wrong:
```
add_theme_page("Theme Panel", "Theme Panel", "manage_options", "theme-panel", "initialize_theme_options", null, 99);
```
The last two parameters shouldn't be there. Check this function in codex [here](https://codex.wordpress.org/Function_Reference/add_theme_page).
EDIT:
What's more, the last parameter (which should be there) `initialize_theme_options` is wrong too, because it should be a callback to a function which would output a content. So for example your `main_settings_callback` function.
SECOND EDIT:
It doesn't work you probably because in the call of `add_settings_section` function you pass in the last parameter `theme-panel` and this page probably doesn't exist. Am I right? Try to replace this parameter for example with `general` and it'll output at the main Setting page.

<p>I am planning to build a WordPress site in which I will setup WooCommerce to sell products. I have created a test site before in which I used my personal email account (gmail) as admin email. Then I tested selling from the site. The problem I faced is that the order confirmation emails were going to spam folder of test client email. And the reason of marking as spam is that The message may not have been sent by [email protected].</p>
<p>How can I prevent the problem in my actual site? Should I start off with an email address such as [email protected] ? Or can I start with my personal email address as the admin email and then later change the admin email? Or can I just use my personal email as admin email and in the WooCommerce email setting I should enter [email protected].</p>
<p>To those who have already built and running WooCommerce sites, What is the best possible option regarding using emails?</p>
<p>Any suggestion will be greatly appreciated.</p>
<p>Thanks.</p>

I am planning to build a WordPress site in which I will setup WooCommerce to sell products. I have created a test site before in which I used my personal email account (gmail) as admin email. Then I tested selling from the site. The problem I faced is that the order confirmation emails were going to spam folder of test client email. And the reason of marking as spam is that The message may not have been sent by \_\_\_\[email protected].
How can I prevent the problem in my actual site? Should I start off with an email address such as \_\_\_\[email protected] ? Or can I start with my personal email address as the admin email and then later change the admin email? Or can I just use my personal email as admin email and in the WooCommerce email setting I should enter [email protected].
To those who have already built and running WooCommerce sites, What is the best possible option regarding using emails?
Any suggestion will be greatly appreciated.
Thanks.

This is wrong:
```
add_theme_page("Theme Panel", "Theme Panel", "manage_options", "theme-panel", "initialize_theme_options", null, 99);
```
The last two parameters shouldn't be there. Check this function in codex [here](https://codex.wordpress.org/Function_Reference/add_theme_page).
EDIT:
What's more, the last parameter (which should be there) `initialize_theme_options` is wrong too, because it should be a callback to a function which would output a content. So for example your `main_settings_callback` function.
SECOND EDIT:
It doesn't work you probably because in the call of `add_settings_section` function you pass in the last parameter `theme-panel` and this page probably doesn't exist. Am I right? Try to replace this parameter for example with `general` and it'll output at the main Setting page.

<p>So, WordPress 4.3 has a new password system as we all know.
Unfortunately, this new system has done away with the ability to <strong>NOT</strong> send new users an email.</p>
<p>My client was using a system where he sent a custom email to his clients, manually registering their emails, and then sending them an email with the login info with a custom message. We are aware that this new system is trying to be more secure, but this isn't working for the amount of control he would like.</p>
<p>I've found the following code in my search for a solution to turn these emails off, but I think they only turn off the notification emails for if a user's email is CHANGED for previously registered users, not when it's first created:</p>
<pre><code>add_filter( 'send_password_change_email', '__return_false');
add_filter( 'send_email_change_email', '__return_false');
</code></pre>
<p>Does anyone know of any way to turn off these initial password emails sent after registration?</p>
<p>Thank you.</p>

You can intercept this email before it is sent using the [`phpmailer_init`](https://developer.wordpress.org/reference/hooks/phpmailer_init/) hook.
By default, this hook fires before any email is sent. In the function below, `$phpmailer` will be an instance of [PHPMailer](https://github.com/PHPMailer/PHPMailer), and you can use its methods to remove the default recipient and manipulate the email before it is sent.
```
add_action('phpmailer_init', 'wse199274_intercept_registration_email');
function wse199274_intercept_registration_email($phpmailer){
$admin_email = get_option( 'admin_email' );
# Intercept username and password email by checking subject line
if( strpos($phpmailer->Subject, 'Your username and password info') ){
# clear the recipient list
$phpmailer->ClearAllRecipients();
# optionally, send the email to the WordPress admin email
$phpmailer->AddAddress($admin_email);
}else{
#not intercepted
}
}
```

This is what I have used to create a custom order status called "Invoiced".
Add this to your theme's functions.php
```
// New order status AFTER woo 2.2
add_action( 'init', 'register_my_new_order_statuses' );
function register_my_new_order_statuses() {
register_post_status( 'wc-invoiced', array(
'label' => _x( 'Invoiced', 'Order status', 'woocommerce' ),
'public' => true,
'exclude_from_search' => false,
'show_in_admin_all_list' => true,
'show_in_admin_status_list' => true,
'label_count' => _n_noop( 'Invoiced <span class="count">(%s)</span>', 'Invoiced<span class="count">(%s)</span>', 'woocommerce' )
) );
}
add_filter( 'wc_order_statuses', 'my_new_wc_order_statuses' );
// Register in wc_order_statuses.
function my_new_wc_order_statuses( $order_statuses ) {
$order_statuses['wc-invoiced'] = _x( 'Invoiced', 'Order status', 'woocommerce' );
return $order_statuses;
}
```
In order to add your new status to the admin Bulk-edit dropdown you have to use javascript.
Add your function to the `admin_footer` action.
My function then looks something like this:
```
function custom_bulk_admin_footer() {
global $post_type;
if ( $post_type == 'shop_order' ) {
?>
<script type="text/javascript">
jQuery(document).ready(function() {
jQuery('<option>').val('mark_invoiced').text('<?php _e( 'Mark invoiced', 'textdomain' ); ?>').appendTo("select[name='action']");
jQuery('<option>').val('mark_invoiced').text('<?php _e( 'Mark invoiced', 'textdomain' ); ?>').appendTo("select[name='action2']");
});
</script>
<?php
}
}
```
The action is added two times because there are one bulk action at the top and another at the bottom of the order list.

I am using ACF (last version) with WordPress (last version too).
I need to modify the post\_object fields of ACF so I use this [`acf/fields/post_object/query`](http://www.advancedcustomfields.com/resources/acf-fields-post_object-query/) function.
All works fine but when I do a var\_dump in the function in the functions.php file, it's impossible to find the result anywhere :(
Does anybody know where I can find this?
My code in the functions.php
```
function member_relation($args, $field, $post) {
var_dump($post); // This var_dump ?
$args['post_parent'] = $post;
return $args;
}
add_filter('acf/fields/post_object/query/name=list_cases', 'member_relation', 10, 3);
```

Probably nowhere because it outputs too early. I recommend to use `error_log` function and turn on `WP_DEBUG_LOG`.
Just add to the `wp-config.php` file somewhere in front of this line:
```
require_once(ABSPATH . 'wp-settings.php');
```
these new lines:
```
define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );
```
Now create in `wp-content` folder a new file `debug.log` and set chmod to 640.
And this line in your code:
```
var_dump($post);
```
replace with this:
```
error_log( var_export( $post, true ) );
```
Now you will find content of the `$post` variable in the `debug.log` file.

<p>I have built an isotope portfolio Wordpress theme which so far is working perfectly:</p>
<p>Anything posted in the custom post type 'portfolio' shows on the homepage and is filterable by the 'portfolio-category' taxonomy using the Isotope JQuery plugin.</p>
<p>So far so good.</p>
<p>However, I wish to make a small improvement.</p>

I have built an isotope portfolio Wordpress theme which so far is working perfectly:
Anything posted in the custom post type 'portfolio' shows on the homepage and is filterable by the 'portfolio-category' taxonomy using the Isotope JQuery plugin.
So far so good.
However, I wish to make a small improvement.
**I only want FEATURED portfolio items to show on the homepage.** For example, only portfolio items with the taxonomy classification of 'featured'. This part I have achieved easily with a custom query (see code snippet below).
The problem I am having is displaying the filterable buttons. I don't want a filterable button to say 'Featured' (defies the point), nor do I want any taxonomies to appear which aren't applicable to any of the featured items (because if clicked, *all* the portfolio items being displayed will disappear).
Here is my current query to show the portfolio items. No problems here:
```
<?php
// Query the portfolio posts
$args = array(
'post_type' => 'portfolio',
'portfolio-category' => 'featured',
'posts_per_page' => -1 );
$loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post();
?>
<!-- PORTFOLIO ITEM -->
<?php endwhile; ?>
```
And here is the code I have currently which outputs the filterable taxonomies. This is what needs addressing.
```
<?php
$terms = get_terms('portfolio-category');
$count = count($terms);
echo '<li class="filtering"><a href="#" title="" data-filter="*" class="button-primary">All</a></li>';
if ( $count > 0 ){
foreach ( $terms as $term ) {
$termname = strtolower($term->name);
$termname = str_replace(' ', '-', $termname);
echo '<li class="filtering"><a href="#" title="" data-filter=".'.$termname.'">'.$term->name.'</a></li>';
}
}
?>
```
Many thanks!

Probably nowhere because it outputs too early. I recommend to use `error_log` function and turn on `WP_DEBUG_LOG`.
Just add to the `wp-config.php` file somewhere in front of this line:
```
require_once(ABSPATH . 'wp-settings.php');
```
these new lines:
```
define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );
```
Now create in `wp-content` folder a new file `debug.log` and set chmod to 640.
And this line in your code:
```
var_dump($post);
```
replace with this:
```
error_log( var_export( $post, true ) );
```
Now you will find content of the `$post` variable in the `debug.log` file.

What is the *keyboard shortcut* key for *updating* a page or post? It could save me a lot of time as rolling down a page draft is time consuming.
|
I was curious about this and checked the Codex on [keyboard shortcuts](https://codex.wordpress.org/Keyboard_Shortcuts), but didn't find it mentioned there.
I searched and found out that this seems to be already solved, e.g. [here](https://wordpress.org/plugins/save-with-keyboard/) and [here](https://github.com/johnbillion/wordpress-keyboard-shortcuts).
I haven't tested out these other plugins so I'm not sure how they solve it, but I decided to take on the challenge and see how this could be solved ;-)
So here's my hack for creating shortcuts for:
```
ctrl+s : Save Draft
ctrl+p : Publish / Update
```
with the following *test plugin* that runs within the [`after_wp_tiny_mce`](https://wordpress.stackexchange.com/a/112192/26350) hook:
```
/**
* Plugin Name: Testing ctrl+s and ctrl+p for saving and publishing posts.
* Plugin URI: https://wordpress.stackexchange.com/a/199411/26350
*/
add_action( 'after_wp_tiny_mce', function()
{?><script>
( function ( $ ) {
'use strict';
$( window ).load( function () {
wpse.init();
});
var wpse = {
keydown : function (e) {
if( e.ctrlKey && 83 === e.which ) {
// ctrl+s for "Save Draft"
e.preventDefault();
$( '#save-post' ).trigger( 'click' );
} else if ( e.ctrlKey && 80 === e.which ) {
// ctrl+p for "Publish" or "Update"
e.preventDefault();
$( '#publish' ).trigger( 'click' );
}
},
set_keydown_for_document : function() {
$(document).on( 'keydown', wpse.keydown );
},
set_keydown_for_tinymce : function() {
if( typeof tinymce == 'undefined' )
return;
for (var i = 0; i < tinymce.editors.length; i++)
tinymce.editors[i].on( 'keydown', wpse.keydown );
},
init : function() {
wpse.set_keydown_for_document();
wpse.set_keydown_for_tinymce();
}
}
} ( jQuery ) );
</script><?php });
```
I added the *wpse.keydown* event-callback to every *tinymce* editor on the page, so the shortcuts would be available from there too.
Note that I use the `after_wp_tiny_mce` hook, as a convinient test-hook on a **vanilla** install, since we're dealing with the *tinymce* javascript object.
When we ship such a plugin, we should enqueue it from a .js file, as usual.
We could also use the `SetupEditor` event of *tinymce*, as mentioned [here](https://wordpress.stackexchange.com/a/192931/26350) by @bonger, but here I've added an extra check to see if *tinymce* is defined, to avoid javascript error on pages where it's not defined:
```
// Keydown for tinymce
if( typeof tinymce != 'undefined' )
{
tinymce.on( 'SetupEditor', function (editor) {
wpse.set_keydown_for_tinymce();
});
}
// Keydown for document
wpse.set_keydown_for_document();
```
We could probably setup native *tinymce* shortcuts as well.
This might need some testing & adjustments, but it seems to work on my install.

I'm fine with `P` tags for most of the content, since it makes styling easier. However I'd like to have `span` `div` `iframe` and possibly other HTML tags to not be placed inside of a `p` for post.
I saw [this question](https://wordpress.stackexchange.com/questions/7090/stop-wordpress-wrapping-images-in-a-p-tag?rq=1) but it doesn't quite solve it. Also, I saw the [linked CSSTricks article](https://css-tricks.com/snippets/wordpress/remove-paragraph-tags-from-around-images/), and tried a sample code that used iFrame on it for my `spans`. Am I doing something wrong with the code? Or what should I do to remove the `p` tags from html tags in my post.
Here's my code that isn't working:
```
function filter_ptags_on_images($content) {
$content = preg_replace('/<p>\s*(<a .*>)?\s*(<img .* \/>)\s*(<\/a>)?\s*<\/p>/iU', '\1\2\3', $content);
return preg_replace('/<p>\s*(<span .*>*.<\/span>)\s*<\/p>/iU', '\1', $content);
} add_filter('the_content', 'filter_ptags_on_images');
```
|
To me you code looks good, I would recommend adding priority as high as 9999
Heres how :
```
add_filter('the_content', 'filter_ptags_on_images', '9999');
```
