| I want to build a plugin to remove all posts by specific users from rest json output.
How can I add a **filter** or **hook** to do that? | If you're using WP 4.7+ you can filter the query using the [`rest_{$this->post_type}_query`](https://developer.wordpress.org/reference/hooks/rest_this-post_type_query/) hook `wp-includes/rest-api/endpoints/class-wp-rest-posts-controller.php:L267`
This is a working example that filters current query by given terms
```
$types = [
'post',
'page',
];
foreach ( $types as $type ) {
add_filter( 'rest_' . $type . '_query', 'filter_rest_query_by_zone', 10, 2 );
}
function filter_rest_query_by_zone( $args, $request ) {
$zones = [ 'term1', 'term2', 'term3' ];
$args['tax_query'] = array(
'relation' => 'AND',
array(
'taxonomy' => 'zones',
'field' => 'term_id',
'terms' => $zones
)
);
return $args;

296,442 | <p>We use SASS when building custom themes, and sometimes clients need a quick change made which is easier to do on the server rather than locally and pushing new changes. To that end, we've installed SASS on our server to watch for file changes. The problem is, if we use the WordPress Appearance Editor to edit SASS files, it defaults to tabs instead of spaces and we use spaces in the office. So SASS compiler (transpiler?) throws an error.</p>
<p>Is there any way to force the WordPress Appearance Editor to use Spaces instead of Tabs? I tried a quick search but everything seemed to be related to the WYSIWYG editor in pages/posts.</p>

Is there any way to force the WordPress Appearance Editor to use Spaces instead of Tabs? I tried a quick search but everything seemed to be related to the WYSIWYG editor in pages/posts. | The WordPress theme/plugin (file) editor uses [CodeMirror](http://codemirror.net/) for syntax highlighting, and with the hook [`wp_enqueue_code_editor`](https://developer.wordpress.org/reference/functions/wp_enqueue_code_editor/) (which is available starting from WordPress version 4.9.0), you can filter the default CodeMirror settings, as in the following example:
```
add_filter( 'wp_code_editor_settings', function( $settings ) {
$settings['codemirror']['indentUnit'] = 2;
$settings['codemirror']['indentWithTabs'] = false;
return $settings;
} );
```
See <http://codemirror.net/doc/manual.html#config> if you'd like to change other CodeMirror settings.
PS: You'd add the code above to the theme's *functions.php* file. |

// Add the rule to the top of the rewrite list
'top' );
}
```
But I still get the 404 page. What have I done wrong?
**Even if I access it with the direct address, I still get 404:**
<http://mywebsite.com/index.php?category_name=arts&paged=2>
Any ideas **why**? | The steps WordPress takes to serve a front end request are roughly-
1. The incoming URL is parsed and converted to query vars.
2. These query vars form the **Main Query**, which is sent to the database.
3. WordPress looks at the results and determines if the request was successful or not, which determines what status header to send- 200 OK, or 404 not found.
4. WordPress loads the template that corresponds to this type of request, for example, a category archive template in the case of your category request, or the 404 template, in the case the main query has no posts.
So the shortest answer to your question as to why you are seeing a 404, is that the main query has no posts.
The query you run in the template and whatever pagination it generates is irrelevant to the main query. This is why you need to *alter the main query* with `pre_get_posts` to customize the results of an archive page.
If you just want pages, you can set post type to just `page`:
```
add_action( 'pre_get_posts', function($q) {
if( !is_admin() && $q->is_main_query() && !$q->is_tax() ) {
$q->set ('post_type', array( 'page' ) );
}
});

Will renaming index.php to index.html and putting my html content will work ? | I **strongly** advise you to heed the advice already given. If your PHP is well structured and you take advantage of caching methods, it won't have a significant increase on your page load time. We've got pages with extremely complex queries that are hardly optimized, but using some clever caching methods, we're able to get those pages served in 500-900ms, or 2-3s for some of the much more complex pages.
It's a much better long term solution than using a static HTML page as your homepage.
*That said* - if you still wish to proceed with a static HTML homepage instead (again, please don't, **especially** if the only reason is "page speed", since there are so many other ways to decrease your page load time)
... Still reading?
Method 1: .htaccess
===================
The… … "generally accepted" way to do this is with a `.htaccess` rule that targets your homepage only, such as `RewriteRule ^$ http://example.com/path-to-html.html [L,R=301]`
Method 2: Page Template
=======================
Alternatively, to maintain *some* semblance to the WordPress ecosystem would be to set up a [Page Template](https://developer.wordpress.org/themes/template-files-section/page-template-files/)
* Add a `home.php` (yes, PHP file) to your active theme directory: `/wp-content/themes/CURRENT-THEME/home.php`.
* Place the following "Page Template Header" code in that file (leave a note to your future self/fellow devs that say where the file is so it's less confusing):
```
<?php
/*
* Template Name: My HTML Homepage
*/
?>
<!-- This page is generated outside of WP by: /wp-content/themes/CURRENT-THEME/home.php -->
<!-- Your HTML Code Here -->
```
* Add a new Page with **Pages** > **Add New** with a recognizable name, such as "My HTML Homepage"
* On the right hand side, in the **Template** selector, choose "My HTML Homepage" as the template.
* In **Settings** > **Reading** change "Your Homepage Displays:" to "A Static Page", and pick the "My HTML Homepage" page you just added.
Method 3: Move your WordPress Install
=====================================
You can also just install WordPress on a subdirectory, have `index.html` in the root directory, and use .htaccess to remove the /wp from your URLs.
Method 4: Don't.
================
Again, I **strongly** urge you to consider other methods:
* Taking advantaged of PHP 7.x and memcache/d
* Caching plugins like WP Super Cache/W3 Total Cache
* Optimizing your images (manually or with WP Smush)
+ Serve images from a CDN
* Optimizing Script/Style delivery (WP Hummingbird can help with this):
+ Combine files where appropriate/able
+ Minify those files
+ Serve those files from a CDN
* Remove unnecessary plugins from WP, optimize JS functions, remove unused CSS selectors, etc. |

In this case you try register a hook before wordpress even finished to "boot". This may work sometimes, but totally not an healthy idea. Use at least the 'init' hook (and even better the 'wp\_loaded' if you can), to trigger you initialization, and do not do anything before that unless you have a very good reason.

296,620 | <p>I'm writing a plugin which collects a pretty large feed. From each feed item a custom post will be created. The feed can also contain images for each item that is uploaded from the remote url. Processing the entire feed can take some time and since I would like to do the processing in the background I am looking into cron as a way to achieve this. Currently I'm doing something like this:</p>
<pre><code>class Cron_Task {
const DEFAULT_TASK_INTERVAL = 30;
public function __construct($taskName, $data) {
add_filter('cron_schedules', array($this, 'addSchedule'));
add_action('cron_task', 'Cron_Task::run');
if (!wp_next_scheduled('cron_task', array($taskName))) {
// Store data in cache.
set_transient($taskName, serialize($data));
wp_schedule_event(time(), $taskName, 'cron_task', array($taskName));
}
}
public static function processItem($data) {
// Execute long running task.
}
public function addSchedule($schedules) {
$schedules['crontask'] = array(
'interval' => self::DEFAULT_TASK_INTERVAL,
'display' => __('Cron_Task'),
);
return $schedules;
}
public static function run($taskName) {
// Get data from cache.
$data = unserialize(get_transient($taskName));
if ($data) {
$item = array_shift($data);
// Process one item.
self::processItem($item);
// Check if we have processed all items.
if (!count($data)) {
delete_transient($taskName);
wp_clear_scheduled_hook('cron_task', array($taskName));
} else {
// Update the items to process.
set_transient($taskName, serialize($data));
}
}
}
}
// When a feed is collected we create a cron_task to be run every 30 seconds.
if (get_feed()) {
$cronTask = new Cron_Task('testEvent', $feed);
}
</code></pre>
<p>The above sort of works, but I think there must be a better way of doing this kind of thing? For instance, since the configured cron tasks will only be run on page load, the task might not be run at the desired interval if there are no visitors.</p>

| I'm writing a plugin which collects a pretty large feed. From each feed item a custom post will be created. The feed can also contain images for each item that is uploaded from the remote url. Processing the entire feed can take some time and since I would like to do the processing in the background I am looking into cron as a way to achieve this. Currently I'm doing something like this:
```
class Cron_Task {
const DEFAULT_TASK_INTERVAL = 30;
public function __construct($taskName, $data) {
add_filter('cron_schedules', array($this, 'addSchedule'));
add_action('cron_task', 'Cron_Task::run');
if (!wp_next_scheduled('cron_task', array($taskName))) {
// Store data in cache.
set_transient($taskName, serialize($data));
wp_schedule_event(time(), $taskName, 'cron_task', array($taskName));
}
}
public static function processItem($data) {
// Execute long running task.
}
public function addSchedule($schedules) {
$schedules['crontask'] = array(
'interval' => self::DEFAULT_TASK_INTERVAL,
'display' => __('Cron_Task'),
);
return $schedules;
}
public static function run($taskName) {
// Get data from cache.
$data = unserialize(get_transient($taskName));
if ($data) {
$item = array_shift($data);
// Process one item.
self::processItem($item);
// Check if we have processed all items.
if (!count($data)) {
delete_transient($taskName);
wp_clear_scheduled_hook('cron_task', array($taskName));
} else {
// Update the items to process.
set_transient($taskName, serialize($data));
}
}
}
}
// When a feed is collected we create a cron_task to be run every 30 seconds.
if (get_feed()) {
$cronTask = new Cron_Task('testEvent', $feed);
}
```
The above sort of works, but I think there must be a better way of doing this kind of thing? For instance, since the configured cron tasks will only be run on page load, the task might not be run at the desired interval if there are no visitors. | The rule of thumb is to never do anything which is not triggered by action or filter.
In this case you try register a hook before wordpress even finished to "boot". This may work sometimes, but totally not an healthy idea. Use at least the 'init' hook (and even better the 'wp\_loaded' if you can), to trigger you initialization, and do not do anything before that unless you have a very good reason.
As for the activation hook, be very careful with trusting it being triggered as it will not be triggered on multisite install, and not when updates are done, so you might as well plan in advance and detect by yourself when DB initialization or updates are required. |

1. `%5B` and `%5D` are *percent-encoded*/URL-encoded version of the `[` (left square bracket) and `]` (right square bracket) characters, respectively. See [Percent-encoding reserved characters](https://en.wikipedia.org/wiki/Percent-encoding#Percent-encoding_reserved_characters) on Wikipedia.
2. You can "change" it using JavaScript, and here's an example of how you can do that without making major changes to the `form` markup that you currently have:
* The only change you need to do is add `alp-search-form` to the `class` attribute of the `form`. The rest can/should remain the same.
* This method works both with and without JavaScript; but of course, without JavaScript, you'll get the "ugly" URL having those URL-encoded square brackets.
**The JS Script**
```
jQuery( function( $ ) {
$( '.alp-search-form' ).on( 'submit', function( e ) {
e.preventDefault();
var url = $( this ).attr( 'action' ),
cat_ids = $( 'select[name="cat_s[]"]', this ).val() || [],
s = /\?[a-z0-9]+/i.test( url ) ? '&' : '?';
url += s + 'alp-search=true';
url += '&cat_s=' + cat_ids.join( ',' );
// "Submits" the form.
//location.href = url; // Uncomment after done testing.
alert( url ); // Remove this after done testing.
} );
} );
```
[Demo on JS Bin](https://jsbin.com/texigecoja/edit?html,js,output)
**Additional Note**
In the PHP script/`function` that processes the form data (or handle the search), you can use this snippet (which uses the [`wp_parse_id_list()`](https://developer.wordpress.org/reference/functions/wp_parse_id_list/) function in WordPress) to grab the selected category IDs:
```
// This variable will/should always be an array.
$cat_ids = isset( $_GET['cat_s'] ) ?
wp_parse_id_list( $_GET['cat_s'] ) : array();

1. `%5B` and `%5D` are *percent-encoded*/URL-encoded version of the `[` (left square bracket) and `]` (right square bracket) characters, respectively. See [Percent-encoding reserved characters](https://en.wikipedia.org/wiki/Percent-encoding#Percent-encoding_reserved_characters) on Wikipedia.
2. You can "change" it using JavaScript, and here's an example of how you can do that without making major changes to the `form` markup that you currently have:
* The only change you need to do is add `alp-search-form` to the `class` attribute of the `form`. The rest can/should remain the same.
* This method works both with and without JavaScript; but of course, without JavaScript, you'll get the "ugly" URL having those URL-encoded square brackets.
**The JS Script**
```
jQuery( function( $ ) {
$( '.alp-search-form' ).on( 'submit', function( e ) {
e.preventDefault();
var url = $( this ).attr( 'action' ),
cat_ids = $( 'select[name="cat_s[]"]', this ).val() || [],
s = /\?[a-z0-9]+/i.test( url ) ? '&' : '?';
url += s + 'alp-search=true';
url += '&cat_s=' + cat_ids.join( ',' );
// "Submits" the form.
//location.href = url; // Uncomment after done testing.
alert( url ); // Remove this after done testing.
} );
} );
```

**Additional Note**
In the PHP script/`function` that processes the form data (or handle the search), you can use this snippet (which uses the [`wp_parse_id_list()`](https://developer.wordpress.org/reference/functions/wp_parse_id_list/) function in WordPress) to grab the selected category IDs:
```
// This variable will/should always be an array.
$cat_ids = isset( $_GET['cat_s'] ) ?
wp_parse_id_list( $_GET['cat_s'] ) : array();

| Basically, I'm trying to override some files of the Uncode theme. But this is not a theme-specific question: it can be applied to any theme. The Uncode theme has a custom dir `'partials'` (`/uncode/partials/`) that contains some layout elements. On my child theme I created a 'partials' folder as well (`my-child-theme/partials`), but the inner files seem not to be overridden. Is it normal? WP docs say that any file of the same name should be overridable, but is seems that's not true. Am I doing something wrong? | It depends entirely on the parent theme. While WordPress will check the child theme for templates in the [Template Hierarchy](https://developer.wordpress.org/themes/basics/template-hierarchy/) and use those if they are present, it's up to theme authors to decide how much overwriting by child themes they want to support for any other files outside this hierarchy.
For example, when including template parts the theme author could use:
```
require 'partials/partial.php';
```
And this would work fine, but if the theme author wanted to support child theming they would use:
```
get_template_part( 'partials/partial' );
```
This is because `get_template_part()` will check the child theme for `partials/partial.php` and use that if it exists, otherwise it will fall back to the parent theme's copy of `partials/partial.php`.
Since 4.7.0, WordPress has added several functions that allow theme authors to support child theming for other files.
[`get_theme_file_uri()`](https://developer.wordpress.org/reference/functions/get_theme_file_uri/) will return a URL for a file in the child theme if it exists, otherwise it will use the parent themes'. This allows themes to support replacing CSS and JS files in child themes.
For example, if the parent theme enqueues a stylesheet like this:
```
wp_enqueue_style( 'custom-style', get_theme_file_uri( 'assets/custom.css' ) );
```
Then a child theme author can replace that stylesheet by just placing `assets/custom.css` in their child theme.
[`get_theme_file_path()`](https://developer.wordpress.org/reference/functions/get_theme_file_path/) will return the *path* for a file in the child theme if it exists, otherwise it will use the parent themes'. This can be used by parent themes to allow child themes to replace entire included PHP files.
For example, if the parent theme included a PHP file like this:
```
include get_theme_file_path( 'inc/template-tags.php' );
```
Then a child theme author could replace `template-tags.php` by just placing `inc/template-tags.php` in their child theme.
So the takeaway here is that WordPress *does* support child themes replacing arbitrary files from their parent theme, but the parent theme author needs to explicitly support it by using the correct functions.
Uncode is a paid theme, so I can't see the code, but I suspect it's not using `get_template_part()`, which is why you can't replace the files in your child theme. Paid themes are often not good 'WordPress citizens' and have pretty spotty support for functionality like this. |
296,778 | <p>So I'm working on a medical site that has a custom post type "doctors". Within this post type are custom taxonomies for "locations" and "procedures". I've created a custom taxonomy-locations.php file to control how my locations pages look, on this page is some general information like contact info, maps, related doctors. I also need to include a list of all procedures offered at each location. Since procedures are attached to each doctor, not to each location, I created a function containing a loop to run through all doctors tagged at the current location and output a comma separated list of all tagged procedures term ids. See below: </p>
<pre><code>// Get the doctors procedures
function location_doctors_procedure_loop() {
$tax_slug = get_query_var( 'locations' );
$args = array(
'posts_per_page' => -1,
'order' => 'DESC',
'post_type' => 'our_team',
'locations' => $tax_slug
);
// The Query
$the_query = new WP_Query( $args );
// The Loop
if ( $the_query->have_posts() ) {
while ( $the_query->have_posts() ) {
$the_query->the_post();
$terms = get_the_terms( $post, 'procedures' );
if ( !empty($terms) ) {
foreach( $terms as $term ) {
echo $term->term_id . ',';
}
}
}
wp_reset_postdata();
}
}
</code></pre>
<p>I then created a function that loops through all active procedure taxonomies and lists them hierarchically as parent, child, grandparent. See below:</p>
<pre><code>// Get the procedures
function tax_location_procedures() {
$doctor_procedures = location_doctors_procedure_loop();
$terms = get_terms( array(
'taxonomy' => 'procedures',
'hide_empty' => true,
'include' => array( $doctor_procedures ),
) );
echo '<h2 class="doctor-bio-procedure-condition-header">Procedures</h2>';
if ( !empty($terms) ) {
echo '<div class="doctor-bio-procedures">';
foreach( $terms as $term ) {
if( $term->parent == 0 ) {
?>
<p class="doctor-bio-procedure-condition-sub-header"><?php echo $term->name; ?></p>
<?php
echo '<ul>';
foreach( $terms as $childterm ) {
if($childterm->parent == $term->term_id) {
echo '<li>' . $childterm->name . '</li>';
echo '<ul>';
foreach( $terms as $grandchildterm ) {
if($grandchildterm->parent == $childterm->term_id) {
echo '<li>' . $grandchildterm->name . '</li>';
}
}
echo '</ul>';
}
}
echo '</ul>';
}
}
echo '</div>';
}
}
</code></pre>
<p>What I'm trying to do is use my first function "location_doctors_procedure_loop()" to populated the 'include' arguments array in "function tax_location_procedures()". The problem I'm having is that while "location_doctors_procedure_loop()" does echo out a comma separated list of the correct term IDs (e.g 231,229,) it does nothing for my 'include" argument because its echoing as a string rather than integers, so it's reading as</p>
<pre><code>'include' => array('231,229,')
</code></pre>
<p>rather than</p>
<pre><code>'include' => array(231,229,)
</code></pre>
<p>I'm stuck on this and have already spent the better part of a day trying to get this to work properly. Any help you guys can provide would be greatly appreciated.</p>

while ( $the_query->have_posts() ) {
$the_query->the_post();
$terms = get_the_terms( $post, 'procedures' );
if ( !empty($terms) ) {
foreach( $terms as $term ) {
echo $term->term_id . ',';
}
}
}
wp_reset_postdata();
}
}
```
I then created a function that loops through all active procedure taxonomies and lists them hierarchically as parent, child, grandparent. See below:
```
// Get the procedures
function tax_location_procedures() {
$doctor_procedures = location_doctors_procedure_loop();
$terms = get_terms( array(
'taxonomy' => 'procedures',
'hide_empty' => true,
'include' => array( $doctor_procedures ),
) );
echo '<h2 class="doctor-bio-procedure-condition-header">Procedures</h2>';
if ( !empty($terms) ) {
echo '<div class="doctor-bio-procedures">';
foreach( $terms as $term ) {
if( $term->parent == 0 ) {
?>
<p class="doctor-bio-procedure-condition-sub-header"><?php echo $term->name; ?></p>
<?php
echo '<ul>';
foreach( $terms as $childterm ) {
if($childterm->parent == $term->term_id) {
echo '<li>' . $childterm->name . '</li>';
echo '<ul>';
foreach( $terms as $grandchildterm ) {
if($grandchildterm->parent == $childterm->term_id) {
echo '<li>' . $grandchildterm->name . '</li>';
}
}
echo '</ul>';
}
}
echo '</ul>';
}
}
echo '</div>';
}
}
```
What I'm trying to do is use my first function "location\_doctors\_procedure\_loop()" to populated the 'include' arguments array in "function tax\_location\_procedures()". The problem I'm having is that while "location\_doctors\_procedure\_loop()" does echo out a comma separated list of the correct term IDs (e.g 231,229,) it does nothing for my 'include" argument because its echoing as a string rather than integers, so it's reading as
```
'include' => array('231,229,')
```
rather than
```
'include' => array(231,229,)
```
I'm stuck on this and have already spent the better part of a day trying to get this to work properly. Any help you guys can provide would be greatly appreciated. | You should be able to change these lines
```
if ( !empty($terms) ) {
foreach( $terms as $term ) {
echo $term->term_id . ',';
}
}
```
to this:
```
if ( !empty($terms) ) {
// create an empty array
$procedures_to_include = array();
foreach( $terms as $term ) {
// now instead of echoing, add each term to the array
$procedures_to_include[] = $term->term_id;
}
}
```
Basically instead of echoing manually, you're creating the array to begin with, and in your `get_terms` call you can just use `$procedures_to_include` directly:
```
$terms = get_terms( array(
'taxonomy' => 'procedures',
'hide_empty' => true,
'include' => $procedures_to_include
) );

296,805 | <p>I have thousands of posts that I am displaying on my home page. I want to control number of posts so for this I am using <code>posts_per_page</code>but it is not working for me. All other arguments works but <code>posts_per_page</code> is not working. I have pagination on this page and <code>posts_per_page</code> works for all other pages of pagination but not for first (main) page.
So for testing purpose i create a blank template that just have one simple WordPress loop and not have pagination or any thing else that is displaying just post title and in this template i have limit on number of posts again but <code>posts_per_page</code> is not working even on this page.
I have tried disabling all plugins but there was no effect so i think this issue is with theme that is setting <code>posts_per_page</code> value dynamically.
I am also resetting the query before this loop using <code>wp_reset_query();</code> and tried this code in <code>functions.php</code> as well.</p>
<pre><code>add_action( 'pre_get_posts', 'set_posts_per_page' );
function set_posts_per_page( $query ) {
global $wp_the_query;
$query->set( 'posts_per_page', 12 );
return $query;
}
</code></pre>
<p>But nothing working for me. I have tried to display query content using <code>var_dump($query->request)</code>and in the query limit was 12 but on page i am still seeing 100+ posts. On WordPress settings page on theme settings page the posts limit is 12 but on front end this limit is not working. Here is the result of this query.</p>
<pre><code>string(489) "SELECT SQL_CALC_FOUND_ROWS wp_mdw75t47kk_posts.ID FROM wp_mdw75t47kk_posts INNER JOIN wp_mdw75t47kk_postmeta ON ( wp_mdw75t47kk_posts.ID = wp_mdw75t47kk_postmeta.post_id ) WHERE 1=1 AND ( wp_mdw75t47kk_postmeta.meta_key = '_imwb_zonpress_post_ctr' ) AND wp_mdw75t47kk_posts.post_type = 'post' AND (wp_mdw75t47kk_posts.post_status = 'publish' OR wp_mdw75t47kk_posts.post_status = 'private') GROUP BY wp_mdw75t47kk_posts.ID ORDER BY wp_mdw75t47kk_postmeta.meta_value+0 DESC LIMIT 0, 12"
</code></pre>
<p>I am also sharing url of this testing page if anybody wants to see this.
<a href="http://ifyougiveagirlaleotard.com/test/" rel="nofollow noreferrer">Test Page link</a>
You will also be able to see this issue on main page as well. For me this is very strange issue because i have tried everything from google but nothing working for me. <BR>
I am using covert store builder theme. Any suggestion will be much appreciated.
Thank you!</p>
<p>Here is complete code for this loop.</p>
<pre><code>wp_reset_query();
$args = Array(
'posts_per_page' => 12
);
$query = new WP_Query( $args );
<?php while ( $query->have_posts() ) : $query->the_post(); ?>
</code></pre>
<p>Then there is some code to display image, title and excerpt and I think this should not effect number of posts. After this these lines are given</p>
<pre><code><?php
endwhile; ?>
</code></pre>
<p>But as i mention i have tried this code in a blank template without pagination but still posts_per_page was not working. So i think an external hook setting this value. I have tried to find out this in theme files but was not successful. I know this is just because of this theme.</p>

| So, I have a loop that works great.
But I need to count how many posts that loop has, and I need to do it via a query to the DB.
My loop looks like:
```
$adsArg = array(
'offset' => $offset,
'post_type' => 'ads',
'meta_key' => $metaKey,
'tax_query' => $taxQuery,
'meta_query' => $metaValue,
);
$adsQuery = new WP_Query($adsArg);
```
And the query I have so far looks like:
```
$wpdb->get_var($wpdb->prepare("SELECT COUNT(ID) FROM " . $table_name . " WHERE post_type = 'ads' AND post_status = 'publish' AND tax_query = " . $taxQuery . " AND meta_query = " . $metaValue . ", array() ) );
```
It's not working and I have no idea the proper way to do that.
The counter has to be done this way, with a direct query to the database. | To get the number of posts you can do it easily without a second query with
```
$adsQuery->post_count;
```
But if there's some reason (I'd love to know the context!) I can't grasp that the same query has to be run twice and to the database directly- to answer your question as to why it's not working:
* Has `$table_name` been defined? Are you using `{$wpdb->prefix}_posts` or `{$wpdb->posts}` in `$table_name`?
* You have no sql string value quotes around `$taxQuery` or `$metaValue` values, so that'll break the query, unless they integers
* Has `$wpdb` has been globally declared?
* Are you using `$wpdb->print_error()` to show the issue?
* If you echo'ed the string query instead of running it, do it look like you expect? whats missing? if you paste it in phpmyAdmin/sqlworkbench does it give you any indication of the problem?
* do you have any errors in your servers errors logs? mysql error logs?
---
I would suggest something like the following
```
<?php
global $wpdb;
$query = "
SELECT COUNT(ID)
FROM {$wpdb->posts}
WHERE post_type = 'ads'
AND post_status = 'publish'
AND tax_query = \"%s\"
AND meta_query = \"%s\"";
// show query
// echo "<pre>{$query}</pre>";
$count = $wpdb->get_var( $wpdb->prepare(
$query,
$taxQuery,
$metaValue
));
echo "<pre>";
if($wpdb->last_error !== '') {
echo " ERROR: ";
$wpdb->print_error();
} else {
echo "Count: {$count}";
}
echo "</pre>";

296,953 | <p>I'm working on a site that uses FacetWP for an events location page and one critical feature is not working. Last year, another dev set up a custom solution to list out FacetWP posts and have them sorted by the state they are in. They used a custom taxonomy for this, but since then, the plugin and is map add-on have had updates that broke that solution.</p>
<p>The dev behind FacetWP has been helping me a bit to rework the custom solution, but he's unavailable now, and I still need some help. He directed me to redo the query to cut out the custom taxonomy and use a custom field instead for the state names as that works better with the plugin. So the query for this template looks like this:</p>
<pre><code><?php
return array(
'post_type' => 'location',
'post_status' => 'publish',

| I'm working on a site that uses FacetWP for an events location page and one critical feature is not working. Last year, another dev set up a custom solution to list out FacetWP posts and have them sorted by the state they are in. They used a custom taxonomy for this, but since then, the plugin and is map add-on have had updates that broke that solution.
The dev behind FacetWP has been helping me a bit to rework the custom solution, but he's unavailable now, and I still need some help. He directed me to redo the query to cut out the custom taxonomy and use a custom field instead for the state names as that works better with the plugin. So the query for this template looks like this:
```
<?php
return array(
'post_type' => 'location',
'post_status' => 'publish',
'posts_per_page' => -1,
'order' => 'ASC',
'meta_key' => 'state',
'orderby' => array(
'meta_value' => 'ASC',
'title' => 'ASC',
),
);
```
This part works great and solved an earlier problem I had. I rebuilt the template's display code like this:
```
<?php
while ($query->have_posts()) {
$state = get_field('state');
$show_header = (empty($prev_state) || $state != $prev_state);
$prev_state = $state;
$query->the_post();
$post_id = get_the_ID();
$title = get_the_title($post_id);
$distance = facetwp_get_distance($post_id);
$distance = (false !== $distance) ? round($distance, 1) . ' miles away' : '';
$coords = get_post_meta($post_id, 'location', true);
$content = get_the_content();
?>
<?php if ($show_header): ?>
<h1 class="state-name"><?php echo esc_html($state); ?></h1>
<?php endif;?>
<div class="post-item" data-title="<?php echo esc_attr($title); ?>"
data-latitude="<?php echo $coords['lat']; ?>" data-longitude="<?php echo $coords['lng']; ?>"
data-distance="<?php echo $distance; ?>">
<div class="post-item-content">
<h2><?php echo $title; ?></h2>
<?php echo $content; ?>
</div>
</div>
<?php
}
wp_reset_query();
?>
```
You can see from [the staging server where I'm testing this](http://d2slive.staging.wpengine.com/locations/) that it's almost working, but not 100% correctly. The posts are not listing by state correctly, and the state title is incorrect above the listings.
It's been a long day and my brain is just not seeing what I need to do to correct this. I could definitely use a nudge in the right direction. | I finally fixed it:
```
<?php
$state_posts = array();
while ($query->have_posts()) {
$query->the_post();
$state = get_post_meta(get_the_ID(), 'state', true);
$state_posts[$state][] = $post;
}
wp_reset_query();
foreach ($state_posts as $state_post => $state_title) {
?>
<h1 class="state-name"><?php echo esc_html($state_post); ?></h1>
<?php
foreach ($state_title as $listing => $single_listing) {
setup_postdata($single_listing);
$post_id = $single_listing->ID;
$title = get_the_title($post_id);
$distance = facetwp_get_distance($post_id);
$distance = (false !== $distance) ? round($distance, 1) . ' miles away' : '';
$coords = get_post_meta($post_id, 'location', true);
$content = get_the_content();
?>
<div class="post-item" data-title="<?php echo esc_attr($title); ?>" data-latitude="<?php echo $coords['lat']; ?>" data-longitude="<?php echo $coords['lng']; ?>" data-distance="<?php echo $distance; ?>">
<div class="post-item-content">
<h2><?php echo $title; ?></h2>
<?php echo $content; ?>
</div>
</div>
<?php
}
wp_reset_postdata();
}
```
I had the post data like `the_title`, `the_content`, etc. in the `while` loop when I needed it in the very last `foreach` loop in order to apply those to only the individual posts. |

I don't think you can have ssl on localhost or an ip address, i guess you know it as you used devfoo.pro. SSL certificate could be generated only for fully qualified domain names.
So, you will need to **buy** a certificate to have things working, out of the box. **Easy and "secure"**.
Or you can self sign one for your self, following a tutorial :-). **Might be difficult** and you will need to accept it in your browser or os.
Or better (at least for me), use this [website](http://www.selfsignedcertificate.com/). It will self sign a certificate for a provided domain. |

| I'm working on a Wordpress theme for a website that makes heavy use of its default media player. In the process of styling its playlists, I found that a core file injects hardcoded characters that can't be made invisible just by using CSS, so I'm a bit clueless about how to hide/remove them.
These characters are injected on 3 different places on each playlist entry:
1. those entries are numbered, but the container is a div instead of an ol, so using list-style-type: none is not possible;
2. they add curly quotes to the song title, but not by using :before and :after;
3. and they add an em dash before the artist name, also not by using the :before pseudo-class.
On wordpress\wp-includes\js\media.php there's a function called **wp\_underscore\_playlist\_templates** which declares the following script:
```
<script type="text/html" id="tmpl-wp-playlist-item">
<div class="wp-playlist-item">
<a class="wp-playlist-caption" href="{{ data.src }}">
{{ data.index ? ( data.index + '. ' ) : '' }}
<# if ( data.caption ) { #>
{{ data.caption }}
<# } else { #>
<span class="wp-playlist-item-title"><?php
/* translators: playlist item title */
printf( _x( '“%s”', 'playlist item title' ), '{{{ data.title }}}' );
?></span>
<# if ( data.artists && data.meta.artist ) { #>
<span class="wp-playlist-item-artist"> — {{ data.meta.artist }}</span>
<# } #>
<# } #>
</a>
<# if ( data.meta.length_formatted ) { #>
<div class="wp-playlist-item-length">{{ data.meta.length_formatted }}</div>
<# } #>
</div>
</script>
```
Of course I could edit this core file, but I don't want to do that. So what should I do? Add a filter on functions.php? Make a JS file? | Inside the shortcode function for playlists, there is this line:
```
do_action( 'wp_playlist_scripts', $atts['type'], $atts['style'] );
```
Hooked into that is `wp_playlist_scripts()` which hooks the templates into the footer:
```
add_action( 'wp_footer', 'wp_underscore_playlist_templates', 0 );
add_action( 'admin_footer', 'wp_underscore_playlist_templates', 0 );
```
So if you want to replace the templates, you can hook into `wp_playlist_scripts` *after* those hooks have been added (so any priority greater than 10), remove the hooks, then hook in your own templates:
```
function wpse_296966_hook_new_playlist_templates() {
// Unhook default templates.
remove_action( 'wp_footer', 'wp_underscore_playlist_templates', 0 );
remove_action( 'admin_footer', 'wp_underscore_playlist_templates', 0 );
// Hook in new templates.
add_action( 'wp_footer', 'wpse_296966_underscore_playlist_templates', 0 );
add_action( 'admin_footer', 'wpse_296966_underscore_playlist_templates', 0 );
}
add_action( 'wp_playlist_scripts', 'wpse_296966_hook_new_playlist_templates', 20 );
```
Then you just need to copy the `wp_underscore_playlist_templates()` function, in its entirety, to a new function in your theme/plugin called `wpse_296966_underscore_playlist_templates()` (or whatever you want, just needs to match the `add_action()` call. Then make any modifications you want to the function to get the markup you wanted.
I would avoid doing anything *too* drastic though, since the scripts likely depend on specific classes, and the general structure. But removing these unwanted characters shouldn't be a problem. |

| I want to change heading tags from child theme but i can't figure out how to add filter to parent theme function.
Parent theme function that i want to change:
```
if(! class_exists('WpkPageHelper')) {
class WpkPageHelper
{
public static function zn_get_subheader( $args = array(), $is_pb_element = false )
{
$config = zn_get_pb_template_config();
self::render_sub_header( $args );
}
public static function render_sub_header( $args = array() )
{
$defaults = array(
'title_tag' => 'h2'
);
}
}
}
```
I want the default title\_tag value to be 'span'. | There is no filter. To filter a value the developer needs to create a filter by wrapping the filterable value in a call to `apply_filters()` with a name for that filter. They have not done that.
What they *have* done is make the `WpkPageHelper` class *pluggable*. This means that it's possible for a child theme to replace the entire class.
Before defining the `WpkPageHelper` class, the parent theme is checking `if(! class_exists('WpkPageHelper')) {`. This is checking if the class has been defined already and only defining the class if it hasn't been. Because child themes are loaded before parent themes this gives you an opportunity to define `WpkPageHelper` before the parent theme does. The parent theme will then use your version.
So all you need to do is copy the code for the `WpkPageHelper` class into your child theme's functions.php file (or another file included in your child theme's functions file) and make the change you want. Just leave out the `class_exists()` check:
```
class WpkPageHelper
{
public static function zn_get_subheader( $args = array(), $is_pb_element = false )
{
$config = zn_get_pb_template_config();
self::render_sub_header( $args );
}
public static function render_sub_header( $args = array() )
{
$defaults = array(
'title_tag' => 'span'
);
}
}
```
This is what WordPress and some themes and plugins are doing when they wrap class and function definitions in conditional statements. You'll occasionally see conditions like `if ( ! function_exists( 'function_name' ) ) {`. This is WordPress or the theme/plugin giving developers an opportunity to define their own versions of these functions or classes for WordPress or the theme/plugin to use instead of their own. |

"text": "<p>Based on your comment you appear to be using the REST API. There's no hook between uploading the file and creating the attachment post that could be used for this purpose in the API endpoint.</p>\n\n<p>The best you can do appears to be to use the <code>rest_insert_attachment</code> action. It provides callback functions with the <code>WP_Post</code> object for the attachment post, and the <code>WP_REST_Request</code> object representing the request. This action is called immediately after the attachment post is created, but before any metadata or sizes are generated. So you would hook into here, check the request for whatever flag you are using to identify media that shouldn't get saved as a post, get the path, then delete the attachment post.</p>\n\n<pre><code>function wpse_297026_rest_insert_attachment( $attachment, $request, $creating ) {\n // Only handle new attachments.\n if ( ! $creating ) {\n return;\n }\n\n // Check for parameter on request that tells us not to create an attachment post.\n if ( $request->get_param( 'flag' ) == true ) {\n // Get file path.\n $file = get_attached_file( $attachment->ID );\n\n // Do whatever you need to with the file path.\n\n // Delete attachment post.\n wp_delete_post( $attachment->ID );\n\n // Kill the request and send a 201 response.\n wp_die('', '', 201);\n }\n}\nadd_action( 'rest_insert_attachment', 'wpse_297026_rest_insert_attachment' )\n</code></pre>\n\n<p>I think it needs to be pointed out that if you're not creating attachments then you shouldn't be using the attachment endpoint. This is why we have to awkwardly kill the request in that code. Everything after <code>rest_insert_attachment</code> assumes the existence of an attachment post and most of the code for the controller for that endpoint is dedicated to creating and managing data that only makes sense for an attachment post. You should probably be creating your own endpoint for this sort of work.</p>\n"

| I need to hook after file uploaded to server, get the file path, and then prevent WordPress from saving the attachment post.
I found this filter `add_filter('attachment_fields_to_save', 'attachment_stuff');` but this is after the attachment post was created, I want to hook before the post save.
**Update 26.03.2018**
I ended up using a custom media endpoint to save the files without saving a attachment post. Full example below in [answer](https://wordpress.stackexchange.com/a/299006/62909) | Based on your comment you appear to be using the REST API. There's no hook between uploading the file and creating the attachment post that could be used for this purpose in the API endpoint.
The best you can do appears to be to use the `rest_insert_attachment` action. It provides callback functions with the `WP_Post` object for the attachment post, and the `WP_REST_Request` object representing the request. This action is called immediately after the attachment post is created, but before any metadata or sizes are generated. So you would hook into here, check the request for whatever flag you are using to identify media that shouldn't get saved as a post, get the path, then delete the attachment post.
```
function wpse_297026_rest_insert_attachment( $attachment, $request, $creating ) {
// Only handle new attachments.
if ( ! $creating ) {
return;
}
// Check for parameter on request that tells us not to create an attachment post.
if ( $request->get_param( 'flag' ) == true ) {
// Get file path.
$file = get_attached_file( $attachment->ID );
// Do whatever you need to with the file path.
// Delete attachment post.
wp_delete_post( $attachment->ID );
// Kill the request and send a 201 response.
wp_die('', '', 201);
}
}
add_action( 'rest_insert_attachment', 'wpse_297026_rest_insert_attachment' )
```
I think it needs to be pointed out that if you're not creating attachments then you shouldn't be using the attachment endpoint. This is why we have to awkwardly kill the request in that code. Everything after `rest_insert_attachment` assumes the existence of an attachment post and most of the code for the controller for that endpoint is dedicated to creating and managing data that only makes sense for an attachment post. You should probably be creating your own endpoint for this sort of work. |
297,041 | <p>Let me give you a scenario of what I'm trying to do. I have a custom post type "customer" and I can go in and "add new customer".

This isn't meant to be a page so I just redirect all of my <a href="http://website.com/customers/" rel="noreferrer">http://website.com/customers/</a>* to somewhere else so that no one goes to these pages (for now).</p>

THANKS! | OK, so there are some arguments of `register_post_type` that you should use.
The crucial arguments for you are:
* `public` - Controls how the type is visible to authors (`show_in_nav_menus`, `show_ui`) and readers (`exclude_from_search`, `publicly_queryable`). If it's false, then `exclude_from_search` will be true, `publicly_queryable` -
false, `show_in_nav_menus` - false, and `show_ui` - false. **So the CPT will be hidden all the way.**
* `exclude_from_search` - Whether to exclude posts with this post type from front end search results. Default: value of the opposite of `public` argument.
* `publicly_queryable` - Whether queries can be performed on the front end as part of parse\_request(). Default: value of `public` argument. **So we have to et it true.**
* show\_ui - Whether to generate a default UI for managing this post type in the admin. Default: value of `public` argument.
* `rewrite` - Triggers the handling of rewrites for this post type. To prevent rewrites, set to false. Default: true and use $post\_type as slug. **So we have to set it false.**
Below you can find the code:
```
$labels = array( /*removed for example*/ );
$args = array(
'labels' => $labels,
'description' => __( 'Description.', 'your-plugin-textdomain' ),
'public' => false,
'show_ui' => true,
'rewrite' => false,
'capability_type' => 'post',
'hierarchical' => false,
/* ... Any other arguments like menu_icon, and so on */
'supports' => array( /* list of supported fields */ )
);
register_post_type( 'customer', $args );
```
This generator maybe helpful, if you don't want to learn all the arguments:

And the list of all arguments, as always, you can find in Codex:

What am I doing wrong. How do I get `check_admin_referer()` to pass?
**Update**
Here is the JS:
```
jQuery(document).ready(function($){
data = {
action: 'hello'
}
$('#stupid_form').submit(function(){
$.post(ajaxurl, data, function(response){
$('#response').html(response);
});
return false;
});
});
``` | In the JS script, include the *nonce* in `data`, as in the following example:
```
jQuery(document).ready(function($){
data = {
action: 'hello',
token: $( '#token' ).val()
}
$('#stupid_form').submit(function(){
$.post(ajaxurl, data, function(response){
$('#response').html(response);
});
return false;
});
});
```
**Additional Note**
```
<?php wp_nonce_field('hello', 'token'); ?>
```
generates a hidden `input` with a markup similar to:
```
<input type="hidden" id="token" name="token" value="d9e3867a0e" />
```
i.e. the *nonce name* becomes the `name` as well as `id` of the `input`.
That explains the `token: $( '#token' ).val()` in the code I provided, where the format is `NONCE_NAME: $( '#NONCE_NAME' ).val()`.
However, you may also target the `name` like so: `token: $( 'input[name="token"]' ).val()` |

| I am creating a clothing store. The clothing are variable products based on size (xs, s, m, l, xl etc..). I am trying to create filters to display products that are in stock, based on a filter. So, clicking the "xs" filter should show products that both have the XS variation, and have that variation in stock.
So far, I've got something like this:
```
$query_args = array(
'post_type' => 'product', 'product_variation',
'posts_per_page' => 12,
'paged' => $paged,
'tax_query' => array(
array(
'taxonomy' => 'pa_sizes',
'field' => 'term_id',
'terms' => 'xs',
),
),
'meta_query' => array(
array(
'key' => '_stock_status',
'value' => 'outofstock',
'compare' => '='
),
)
);
$query = new WP_Query($query_args);
```
I know right now it's searching for "outofstock" but that was just a test, and not even this comes up with any products, even though I have created some products with some sizes out of stock. | In the JS script, include the *nonce* in `data`, as in the following example:
```
jQuery(document).ready(function($){
data = {
action: 'hello',
token: $( '#token' ).val()
}
$('#stupid_form').submit(function(){
$.post(ajaxurl, data, function(response){
$('#response').html(response);
});
return false;
});
});
```
**Additional Note**
```
<?php wp_nonce_field('hello', 'token'); ?>
```
generates a hidden `input` with a markup similar to:
```
<input type="hidden" id="token" name="token" value="d9e3867a0e" />
```
i.e. the *nonce name* becomes the `name` as well as `id` of the `input`.
That explains the `token: $( '#token' ).val()` in the code I provided, where the format is `NONCE_NAME: $( '#NONCE_NAME' ).val()`.
However, you may also target the `name` like so: `token: $( 'input[name="token"]' ).val()` |

First, you could sent an Ajax request to your server, sending only the `dataString` variable.
Then, you can use either `cURL` or [`wp_remote_get()`](https://codex.wordpress.org/Function_Reference/wp_remote_get) on the server to access the real API.

Thank you very much. | If you're using PHP > 5.3, then you can use a closure on the `the_content` filter. This filter needs to be added after the `$variable` has been defined and before the `the_content` filter has fired.
```

| I’m trying to add a custom field to image and gallery edit screen.
I’m aware there are similar questions here, although answers either don’t work with the current version or they add field only to **upload** screen while I need a field to be visible in all **edit** screens (see below).
For this, I believe, you’ll have to mess with *backbone.js* as `attachment_fields_to_edit` only adds to upload screen.
Adding field with attachment\_fields\_to\_edit
----------------------------------------------
[](https://i.stack.imgur.com/sb4otm.png)
↑ This is upload image screeen. Here **Style** is added with `attachment_fields_to_edit` filter, and my\_field is added with ACF plugin.
But they are missing in edit screen in the post
-----------------------------------------------
[](https://i.stack.imgur.com/XUyV9m.png)
↑ Click edit on the actual post
[](https://i.stack.imgur.com/wiJ43m.jpg)
↑ No style & my\_field fields!
The question
------------
How to add fields to still have them on the edit screen? Ideally answer will include adding fields to gallery edit screen if it’s a similar process
This question is really important for me so **I’ll be adding a 100 rep** bounty when it’s available.
Thanks! | Here is the working code (working fine for me), did you tried this? Just add to theme 'functions.php' and change the custom field names as needed.
```
//function to add custom media field
function custom_media_add_media_custom_field( $form_fields, $post ) {
$field_value = get_post_meta( $post->ID, 'custom_media_style', true );
$form_fields['custom_media_style'] = array(
'value' => $field_value ? $field_value : '',
'label' => __( 'Style' ),
'helps' => __( 'Enter your style' ),
'input' => 'textarea'
);
return $form_fields;
}
add_filter( 'attachment_fields_to_edit', 'custom_media_add_media_custom_field', null, 2 );
//save your custom media field
function custom_media_save_attachment( $attachment_id ) {
if ( isset( $_REQUEST['attachments'][ $attachment_id ]['custom_media_style'] ) ) {
$custom_media_style = $_REQUEST['attachments'][ $attachment_id ]['custom_media_style'];
update_post_meta( $attachment_id, 'custom_media_style', $custom_media_style );
}
}
add_action( 'edit_attachment', 'custom_media_save_attachment' );

For example, instead of a grid of thumbnails I'd like to show a slideshow of images. Is it possible? If so, how? Any help would be appreciated. | Ok, I've been playing with this for a little bit and have managed to change the output of the Gallery block, with the following caveats:
* The preview does not match the output. I think this is possible but appears to be a bit more involved.
* Certain classes and markup are required in the output for the block to be able to parse the content and keep it editable. These classes have front-end styles that will need to be dealt with. I'm not sure at this point if there is a way to filter how the block does this. If it were possible it might not even be a good idea if it means Gallery blocks are broken when a theme or plugin is deactivated. A totally new block would probably be the way to go for situations where this would be required.
* I'm not really sure how image sizes work at this stage.
* The method of JavaScript hooks used might not be relevant in the final release. Gutenberg uses [`@wordpress/hooks`](https://www.npmjs.com/package/@wordpress/hooks) while discussion about what hooks system to use in Core [is ongoing](https://core.trac.wordpress.org/ticket/21170).
* Since the output of Blocks is saved as HTML, not a shortcode or meta, it won't be possible to modify the output of existing Galleries without editing them.
The first thing we need to do is register a script. This is done with `wp_enqueue_scripts()`, but on the `enqueue_block_editor_assets` hook.
The script should have the `wp-blocks` script as a dependency. It is almost certainly already loaded in the editor, but making it a dependency presumably ensures it is loaded before our script.
```
function wpse_298225_enqueue_block_assets() {
wp_enqueue_script(
'wpse-298225-gallery-block',
get_theme_file_uri( 'block.js' ),
['wp-blocks']
);
}
add_action( 'enqueue_block_editor_assets', 'wpse_298225_enqueue_block_assets' );
```
The HTML for a block's output is handled by the `save()` method of the block. You can see the Gallery block's in [this file](https://github.com/WordPress/gutenberg/blob/master/blocks/library/gallery/index.js).
At this stage (March 2018) Gutenberg supports a filter on the save method of blocks, [`blocks.getSaveElement`](https://github.com/WordPress/gutenberg/blob/master/docs/extensibility.md#blocksgetsaveelement). We can add a hook to this in JavaScript like this:
```
wp.hooks.addFilter(
'blocks.getSaveElement',
'wpse-298225',
wpse298225GallerySaveElement
)
```
The first argument is the hook name, the 2nd argument is - I think - a namespace, and the last argument is the callback function.
Since we are replacing the `save()` method of the block, we need to return an new element. However, this is not a normal HTML element we need to return. We need to return a *React* element.
When you look at the original block’s `save()` method what you see is JSX. React, which Gutenberg uses under-the-hood, supports it for rendering elements. See [this article](https://reactjs.org/docs/introducing-jsx.html) for more on that.
JSX normally requires a build step, but since I'm not introducing a build step for this example, we need a way to create an element without JSX. React provides this with `createElement()`. WordPress provides a wrapper for this and other react functionality in the form of `wp.element`. So to use `createElement()` we use `wp.element.createElement()`.
In the callback function for `blocks.getSaveElement` we get:
* `element` The original Element created by the block.
* `blockType` An object representing the block being used.
* `attributes` The properties of the block instance. In our example this includes the images in gallery and settings like the number of columns.
So our callback function needs to:
* Return the original element for non-block galleries.
* Take the attributes, particularly the images, and create a new React element out of them representing the gallery.
Here is a complete example that simply outputs a `ul` with a class, `my-gallery`, and `li`s for each image with the class `my-gallery-item` and and `img` in each one with the `src` set to the image URL.
```
function wpse298225GallerySaveElement( element, blockType, attributes ) {
if ( blockType.name !== 'core/gallery' ) {
return element;
}
var newElement = wp.element.createElement(
'ul',
{
'className': 'wp-block-gallery my-gallery',
},
attributes.images.map(
function( image ) {
return wp.element.createElement(
'li',
{
'className': 'blocks-gallery-item my-gallery-item',
},
wp.element.createElement(
'img',
{
'src': image.url,
}
)
)
}
)
)
return newElement
}
```
Some things to take note of:
* The original gallery block finds images by looking for `ul.wp-block-gallery .blocks-gallery-item`, so this markup and those classes are required for editing the block to be possible. This markup is also used for the default styling.
* `attributes.images.map` is looping over each image and returning an array of child elements as the content for the main element. Inside these elements there is another child element for the image itself. |

| I want to check plugin version using following API
```
https://api.wordpress.org/stats/plugin/1.0/{slug}
```
For that how can I get Slug of All Active Plugins ? | Use option `active_plugins` to get all plugin init files. e.g.
```
$current = get_option( 'active_plugins', array() );
// print_r( $current );
```
Here, `htmlpress` is the plugin slug.

| I want to check latest version of plugin is available or not. For that I required current version of active plugins. How can I get current version of all active plugins programmatically ? | Problem Analysis
================
To get information about installed plugins, which provides plugin's version, we'll use `get_plugins()` function. Keep in mind, that this function is available in back end only, so our code must reside there. Data, returned from this function, does not tell us, which plugins are active. To filter out active plugins, we'll use `get_option('active_plugins')` function. It will return a simple array, consisting of keys to array returned by `get_plugins()` function.
Code
====
The best illustration for our method will be the actual code. We'll create a dashboard widget, displaying three-column table, showing active plugin's name, its current version, and its newest version in WordPress repository. Let's create `myDashboardWidget.php` file, and put the code below, in it.
```
<?php
if(is_admin()) { // make sure, the following code runs in back end
// returns version of the plugin represented by $slug, from repository
function getPluginVersionFromRepository($slug) {
$url = "https://api.wordpress.org/plugins/info/1.2/?action=plugin_information&request[slugs][]={$slug}";
$response = wp_remote_get($url); // WPOrg API call
$plugins = json_decode($response['body']);
// traverse $response object
foreach($plugins as $key => $plugin) {
$version = $plugin->version;
}
return $version;
}
// dashboard widget's callback
function activePluginsVersions() {
$allPlugins = get_plugins(); // associative array of all installed plugins
$activePlugins = get_option('active_plugins'); // simple array of active plugins
// building active plugins table
echo '<table width="100%">';
echo '<thead>';
echo '<tr>';
echo '<th width="50%" style="text-align:left">Plugin</th>';
echo '<th width="20%" style="text-align:left">currVer</th>';
echo '<th width="20%" style="text-align:left">repoVer</th>';
echo '</tr>';
echo '</thead>';
echo '<tbody>';
// traversing $allPlugins array
foreach($allPlugins as $key => $value) {
if(in_array($key, $activePlugins)) { // display active only
echo '<tr>';
echo "<td>{$value['Name']}</td>";
echo "<td>{$value['Version']}</td>";
$slug = explode('/',$key)[0]; // get active plugin's slug
// get newest version of active plugin from repository
$repoVersion = getPluginVersionFromRepository($slug);
echo "<td>{$repoVersion}</td>";
echo '</tr>';
}
}
echo '</tbody>';
echo '</table>';
}
// widget's registration
function fpwAddDashboardWidget() {
wp_add_dashboard_widget(
'active_plugins_versions', // widget's ID
'Active Plugins Versions', // widget's title
'activePluginsVersions' // widget's callback (content)
);
}
add_action('wp_dashboard_setup', 'fpwAddDashboardWidget');
}
```
Now, place this file in `/wp-content/mu-plugins/` directory.
Code Explained
==============
Read comments within `myDashboardWidget.php` file.
**Note:** if there is no version shown in third column of the table, the plugin is not in repository (either premium, or discontinued).
Code Efficiency
===============
Efficiency of this sample code can be much improved. The WPOrg API request is made for each plugin. `/plugins/info/1.2/` version of the API, allows getting info for all plugin slugs with one request only. |

| I'm trying to upload files using AJAX and I'm hooking in my functions so they get called within admin-ajax. I can't get it to work tough, and I didn't have any idea what was wrong or where to look at all. I narrowed it down, however, by modifying admin-ajax.php a little bit:

```
My AJAX request has dataType: 'json' in it, so my success function does get called(if I remove the $response declaration and the call to wp\_send\_json, the error one gets called, returning the entire page as a response with the statusText being "parsererror").
Anyway, here's my AJAX script:
```
$( '#user-file' ).change( function( event ) {
var formData = new FormData();
formData.append( "userfile", $(this)[0].files[0] );
formData.append( "action", "vibesoft_files_upload" );

success: function( data ) {
if ( data.error != 'none' ) {
console.log( 'Error: ' + data.error );
console.log( 'Request: ' + data.req );
return;
}
```
It's not the entire function, which is wrapped inside `(function($) { ... })(jQuery);` so I can use $ instead of jQuery. The `console.log( 'Request: ' + data.req );` outputs:
```
Request: array(
)
```
I also tried outputting the $\_POST and $\_FILES and they, too, are empty arrays. If I send them back using(instead of the JSON return):
```
var_dump( $_REQUEST );
exit;
```
I get `array(0) {}` back in the console.
So, yeah, I have no idea why am I getting an empty array... | Here's the problem:
```
var formData = new FormData();
formData.append( "userfile", $(this)[0].files[0] );
formData.append( "action", "vibesoft_files_upload" );
formData.append( "_wpnonce", vbsoft.nonce_upload );
console.log( formData );
$.ajax({
type: "post",
url: vbsoft.ajax_url,
data: formData,
```
Specifically:
```
var formData = new FormData();
```
Nowhere in the jQuery documentation does it say that `data` accepts a `FormData` object for the `data` parameter:

<https://api.jquery.com/jQuery.ajax/>
The solution is to instead use an object, e.g.:
```
var formData = {
"userfile": $(this)[0].files[0],
"action": "vibesoft_files_upload",
"_wpnonce": vbsoft.nonce_upload
};

[](https://i.stack.imgur.com/D2cW6.png) | You can add a metabox in the edit screen with
```
add_action( 'add_meta_boxes', function () {
add_meta_box(
'yourcustom_sectionid',
__( ' Custom Meta Box', 'yourtextdomain' ),
function ( $post ) {
wp_nonce_field( plugin_basename( __FILE__ ), 'yourcustom_noncename' );
$cstm = get_post_meta(get_the_ID(),'yourcustom_meta',true);
echo "<pre>".print_r($cstm,true)."</pre>";
},
'page'
);
} );
```
You can query posts with [`get_posts()`](https://codex.wordpress.org/Template_Tags/get_posts) and add some check boxes inside that metabox
```
$getPostsToSelect = get_posts('post_type=post&numberposts=-1');
foreach ($getPostsToSelect as $aPostsToSelect) {
?>
<label>
<input
type='checkbox'
name='yourcustom_meta[]'
class='postsToSelect'
value='<?php echo $aPostsToSelect->ID ?>'
/>
<?php echo $aPostsToSelect->post_title ?>
</label><br />
<?php
}
```
You'd than need some jQuery to restrict to only 2 selected. It'd be somthing like
```
var limit = 2;
jQuery('input.single-checkbox').on('change', function(evt) {
if(jQuery('input.single-checkbox:checked').length > limit) {
this.checked = false;
}
});
```
You'd save it all with somthing like :
```
add_action( 'save_post', function ( $post_id ) {
if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE )
return;
if ( !wp_verify_nonce( $_POST['yourcustom_noncename'], plugin_basename( __FILE__ ) ) )
return;
if ( 'page' == $_POST['post_type'] ) { // not the Post Type
if ( !current_user_can( 'edit_page', $post_id ) )
return;
} else {
if ( !current_user_can( 'edit_post', $post_id ) )
return;
}
update_post_meta($post_id,'yourcustom_meta',$_POST['yourcustom_meta']);
});
```
Then in your `single.php`, or wherever your loop is that you want them to show, you'd just call them up:
```
$cstm = get_post_meta(get_the_ID(),'yourcustom_meta',true);
foreach ($cstm as $aPostToDisplay) {
echo "<pre>{$aPostToDisplay->ID} - {$aPostToDisplay->post_title}</pre>";
}
```
Please note that I free handed this (not tested), so copy/paste will not work.. It's more of a logic guid.
I've assumed without double checking that `name='yourcustom_meta[]'` will pass only the checked ones to `$_POST['yourcustom_meta']`, but you might want to confirm that.
I've also used anonymous functions, which probably shouldn't be used if this is a for-public plugin/theme. |
298,445 | <p>I have created a new WordPress site in a folder inside of another WordPress site.</p>
<p>Example
- mainsite.com
- mainsite.com/secondsite</p>
<p>I have created a plugin and I use <code>$wpdb</code> to insert data to the database and the plugin inserts the data to the database of the first/parent site.</p>
<p>The code I use to include <code>$wpdb</code> is the following:</p>
<pre><code>$path = $_SERVER['DOCUMENT_ROOT'];
include $path . '/wp-load.php';
include $path . '/wp-config.php';
include $path . '/wp-includes/wp-db.php';
global $wpdb;

| I have created a new WordPress site in a folder inside of another WordPress site.
Example
- mainsite.com
- mainsite.com/secondsite
I have created a plugin and I use `$wpdb` to insert data to the database and the plugin inserts the data to the database of the first/parent site.
The code I use to include `$wpdb` is the following:
```
$path = $_SERVER['DOCUMENT_ROOT'];
include $path . '/wp-load.php';
include $path . '/wp-config.php';
include $path . '/wp-includes/wp-db.php';
global $wpdb;
```
How can I fix that? | `$_SERVER['DOCUMENT_ROOT'];` is not going to include `secondsite`. So all the files, including `wp-config.php` with the database details, are coming from the root public directory.
To get the current directory, including subdirectories, use any of these:
```
getcwd();
dirname(__FILE__);
basename(__DIR__);
```
But if your file is in a deeper folder, you can't find the `secondsite` directory without specifying it (or scanning directories to find a WordPress installation). So you need to manually specify it like so:
```
$path = $_SERVER['DOCUMENT_ROOT'] . '/secondsite';
```
But your problem is that you're doing AJAX wrong. You shouldn't be sending AJAX requests directly to a file in your plugin. You should be [using the AJAX hooks](https://developer.wordpress.org/plugins/javascript/ajax/) or [adding a custom endpoint to the REST API](https://developer.wordpress.org/rest-api/extending-the-rest-api/adding-custom-endpoints/). |

Please where am I missing it? | You need to change the data that you are sending in the ajax request.
For ajax to work in WordPress you need to send the **action** variable in ajax post request.
Change
```
data: {package: package},
```
to
```
data: {action: 'ajaxAutopopulate', package: package}
```
Also you can use the wordpress default function
```
wp_send_json( $response )
```
for encoding of data
and
```
admin_url( 'admin-ajax.php' )
```
for the ajax file url.
If you have your js code in a separate file , you may need to use
```
wp_localize_script
```
to pass the value to the js file |

To fix this, one can easily tell that you're calling `get_the_content` or `get_the_excerpt` outside the loop.

| I created my own contact form and I'm using `WP_List_Table` to display submitted forms in wp-admin. I edited [this](https://github.com/pmbaldha/WP-Custom-List-Table-With-Database-Example) example WP\_List\_Table from **github** and it works fine.
This is how I add my custom admin menu page:
```
function contact_form_create() {
add_menu_page('Contact Forms', 'Contact Forms', 'administrator', 'contact-form', 'contact_form_page_handler');
}
add_action('admin_menu', 'contact_form_create');
```
But now I want to make a notification. So when visitor submit a contact form, then my table shows me a notification in wp-admin like this:
 | OK, so it has nothing to do with WP\_List\_Table, to be precise. All you need to do is to add some additional info during registration of your custom admin page.
There are two classes used by WordPress to display these notification bubbles:
* update-plugins
* awaiting-mod
Your notifications have nothing to do with plugins, so it will be nicer to use the second class. You should change your function like this:
```
function contact_form_create() {
$notification_count = 2; // <- here you should get correct count of forms submitted since last visit
add_menu_page(
'Contact Forms',
$notification_count ? sprintf('Contact Forms <span class="awaiting-mod">%d</span>', $notification_count) : 'Contact Forms',
'administrator', // <- it would be nicer to use capability in here 'manage_options'
'contact-form',
'contact_form_page_handler'
);
}
add_action('admin_menu', 'contact_form_create');
```
So the main change is that if there are some notifications to show, then we add `<span class="awaiting-mod">%d</span>` to title of that page.
The only thing you'll have to do now is to get correct number of form submits since last visit. The easiest way to do this would be store last ID of submited form record in your custom DB table as some option and counting new records based on this ID. But it's hard to say exactly how to count them, since I have no info about how you store this submitted forms and so on, so I leave this part to you. |

I know this question is a little out of date and our question/issue is technically regarding an [Azure Wordpress Resource](https://azure.microsoft.com/en-us/blog/how-to-host-a-scalable-and-optimized-wordpress-for-azure-in-minutes/) not a hosted environment... but I thought it might be helpful to answer for future readers.
**Background/Issue**
We spun up an *Azure Worpress resource* and migrated our site to it using [updraft](https://updraftplus.com/). Once transferred and browsing the site we had the same issue:
`The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.`
**Solution**
[Tom](https://wordpress.stackexchange.com/users/736/tom-j-nowell) mentioned above that it's an Azure issue. And looking further in, it's more specifically it ended up being an IIS `web.config` issue. Here are steps we took to correct it:
**Getting to the web.config file**
1. In the Azure portal go to the wordpress resource and then to *Advanced Tools*:
[](https://i.stack.imgur.com/kdKul.png)
2. Once we got to the Kudu interface we navigated to the *Debug console* -> *PowerShell* (or *CMD* if you prefer). Then navigated to the root wordpress directory where the `web.config` lives:
[](https://i.stack.imgur.com/6Zex3.png)
**Editing the web.config file**
1. After opening it up the problem was pretty obvious. Somehow Azure spun up the wordpress resource without adding the correct rewrite rules. Or maybe our updraft transfer overwrote it...
[](https://i.stack.imgur.com/lZyF0.png)
2. So we just added the appropriate rewrite rules. (for an *azure wordpress resource*)
[](https://i.stack.imgur.com/ZG53E.png)

Lets assume this is term number 5, the result is:</p>\n\n<pre><code> $term = 5;\n if ( $term->parent == 'tradeshow' ) {\n</code></pre>\n\n<p>Which won't work. <code>$term</code> is a number, not an object, so you cant do <code>->parent</code> on it.</p>\n\n<p>The fix is to just use the queried object directly:</p>\n\n<pre><code> $term = get_queried_object();\n</code></pre>\n\n<p>Which leads us to the next problem:</p>\n\n<pre><code> if ( $term->parent == 'tradeshow' ) {\n</code></pre>\n\n<p>The parent isn't a string, it's a term ID. <code>0</code> if there is no parent, else it's the ID of the parent term, as shown if we look up <code>WP_Term</code>:</p>\n\n<pre><code>/**\n * ID of a term's parent term.\n *\n * @since 4.4.0\n * @var int\n */\npublic $parent = 0;\n</code></pre>\n\n<p>So you need to acquire the tradeshow term in advance to find out its ID. Usually, for these scenarios, developers will not hardcode the slug, but instead provide a setting that lists terms, and store the ID as an option to avoid this kind of lookup, and increase flexibility</p>\n\n<p>But in this case you can use the <code>get_term_by</code> function, e.g.</p>\n\n<pre><code>$tradeshow = get_term_by('slug', 'tradeshow', 'events')\n</code></pre>\n\n<p>Then using:</p>\n\n<pre><code>$tradeshow->term_id === $term->parent\n</code></pre>\n\n<h2>Problems and Advice</h2>\n\n<p>These are additional items I wanted to mention that are unrelated</p>\n\n<h3>Debugging</h3>\n\n<p>Using <code>var_dump</code>, a debugger, or some other tool to see what the contents of <code>$term</code> was would have revealed these problems.</p>\n\n<p>Additionally, PHP error logs will be full of warnings and notices pointing at the if statement for trying to do the equivalent of <code>5->parent</code> which makes no sense to PHP. Pay attention to error logs.

| I'm attempting to make an archive template that will apply only to subcategories of a particular term. My structure looks something like this:
* Events (main taxonomy)
+ Tradeshow
- Show subcat 1
- Show subcat 2
+ Other taxonomies
I want `Show subcat 1` and `Show subcat 2` (and any other subcategories) to all get the same archive template. This is one of my attempts at it, which is definitely not working. Here's the code from my `functions.php`.
```
add_filter( 'template_include', 'kd_event_subcategory_archive' );
function kd_event_subcategory_archive( $template ) {
$term = get_queried_object()->term_id;
if ( $term->parent == 'tradeshow' ) {
$event_subcat = locate_template( 'taxonomy-tradeshow-subcategory.php' );
return $event_subcat;
}
return $template;
}
```
I can't seem to figure out how to properly check if a term is the child of my `tradeshow` term. | There are two problems that have thwarted your check:
```
$term = get_queried_object()->term_id;
if ( $term->parent == 'tradeshow' ) {
```
Starting with:
```
$term = get_queried_object()->term_id;
```
Here `$term` contains the ID of a term, not a term object. Lets assume this is term number 5, the result is:
```
$term = 5;
if ( $term->parent == 'tradeshow' ) {
```
Which won't work. `$term` is a number, not an object, so you cant do `->parent` on it.
The fix is to just use the queried object directly:
```
$term = get_queried_object();
```
Which leads us to the next problem:
```
if ( $term->parent == 'tradeshow' ) {
```
The parent isn't a string, it's a term ID. `0` if there is no parent, else it's the ID of the parent term, as shown if we look up `WP_Term`:
```
/**
* ID of a term's parent term.
*
* @since 4.4.0
* @var int
*/
public $parent = 0;
```
So you need to acquire the tradeshow term in advance to find out its ID. Usually, for these scenarios, developers will not hardcode the slug, but instead provide a setting that lists terms, and store the ID as an option to avoid this kind of lookup, and increase flexibility
But in this case you can use the `get_term_by` function, e.g.
```
$tradeshow = get_term_by('slug', 'tradeshow', 'events')
```
Then using:
```
$tradeshow->term_id === $term->parent
```
Problems and Advice
-------------------
These are additional items I wanted to mention that are unrelated
### Debugging
Using `var_dump`, a debugger, or some other tool to see what the contents of `$term` was would have revealed these problems.
Additionally, PHP error logs will be full of warnings and notices pointing at the if statement for trying to do the equivalent of `5->parent` which makes no sense to PHP. Pay attention to error logs. I'd recommend using the query monitor plugin as an easy way to catch unexpected warnings
### The Queried object isn't always a term
This code will run on every page load:
```
add_filter( 'template_include', 'kd_event_subcategory_archive' );
function kd_event_subcategory_archive( $template ) {
$term = get_queried_object()->term_id;
if ( $term->parent == 'tradeshow' ) {
```
But what if the user visits a date archive or an author archive? Now the code runs anyway, generating errors. So this filter needs tests to check if the user is on a taxonomy archive, and that the taxonomy matches.
It may even be a singular post, and if the trade show term has a term ID of 5, and you're on the post or page with ID 5, then you'll get a post showing on a taxonomy archive.
I suspect though that it would be easier to use a separate taxonomy.

| I have a javascript snippet that I want to inject into the footer of the page. It's a tracking code, let's say similar to Google analytics. It has no dependencies, it's a standalone snippet.
I can do something like this
```
function render_tracking_code(){
wp_enqueue_script( 'depends-js', 'https://rdiv.com/dummy.js', array(), '0.01', true );
wp_add_inline_script( 'depends-js', 'aWholeBunchOfJavascriptCode' );
}
add_action( 'wp_enqueue_scripts', 'render_tracking_code' );
```
Seems a little stupid (dummy.js is a blank file), but works. Is there a way to skip the dependency? | `wp_add_inline_style()` - without dependency
--------------------------------------------
The `wp_add_inline_style()` can be used without a source file dependency.
Here's an [example](https://wordpress.stackexchange.com/a/282868/26350) from @Flix:
```
wp_register_style( 'dummy-handle', false );
wp_enqueue_style( 'dummy-handle' );
wp_add_inline_style( 'dummy-handle', '* { color: red; }' );
```
where we would hook this into the `wp_enqueue_scripts` action.
`wp_add_inline_script()` - without dependency
---------------------------------------------
According to ticket [#43565](https://core.trac.wordpress.org/ticket/44551), similar will be supported for `wp_add_inline_script()` in version `4.9.9` `5.0` (thanks to @MarcioDuarte, @dev101 and @DaveRomsey for the verification in comments):
```
wp_register_script( 'dummy-handle-header', '' );
wp_enqueue_script( 'dummy-handle-header' );
wp_add_inline_script( 'dummy-handle-header', 'console.log( "header" );' );
```
that will display the following in the *header*, i.e.between the `<head>...</head>` tags:
```
<script type='text/javascript'>
console.log( "header" );
</script>
```
To display it in the *footer*:
```
wp_register_script( 'dummy-handle-footer', '', [], '', true );
wp_enqueue_script( 'dummy-handle-footer' );
wp_add_inline_script( 'dummy-handle-footer', 'console.log( "footer" );' );
```
The default of `$position` input argument in `wp_add_inline_script()` is `'after'`. The `'before'` value prints it above `'after'`. |

Is there anyway to do the same, but with a variation sku? | I was stuck on a very similar problem. I couldn't find anything in the woocommerce code that would let you directly look up the parent product from the variation sku.
But, as product variations are stored in the `wp_posts` table with the type `product_variation`, and the SKUs are stored in the `wp_post_meta` table, it's easy to look up the product variation using a meta query with the `get_posts()` wordpress function.
```
$args = array(
'post_type' => 'product_variation',
'meta_query' => array(
array(
'key' => '_sku',
'value' => 'PRODUCT_SKU',
)
)
);
$posts = get_posts( $args);
```
This should return your matching `product_variation` custom post type.
Once you have this then you can look up the parent product using the column `post_parent` that WooCommerce uses to link a variation to the parent variable product.
Turning that into a function is pretty straight forward:
```
function wc_get_product_id_by_variation_sku($sku) {
$args = array(
'post_type' => 'product_variation',
'meta_query' => array(
array(
'key' => '_sku',
'value' => $sku,
)
)
);
// Get the posts for the sku
$posts = get_posts( $args);
if ($posts) {
return $posts[0]->post_parent;
} else {
return false;
}
}
```
I use this in my site and it works great. Hope that helps. |

When I go to <http://www.philenglish.com.cn/wp-login.php> I get a 404 error, which is something such plugins also do: they make the default login URLs unavailable in an attempt to make your site more secure.
If you don't know what the login URL is changed to, I would first disable any security plugins installed on the site. You mention you've already tried disabling plugins, but looking at your site's source code, I can see there are still plugins active. So I would double-check you've really disabled your plugins.
An easy way would be to connect to your site through FTP and navigate to your plugins folder. Normally you would find this here:
```
wp-content > plugins
```
Your can either look in your plugins folder and find the plugin that might cause this issue. And then disable it by temporarily renaming the folder.
Or you can disable all plugins at once by temporarily renaming the whole plugins folder.
As an aside: this is the quickest way to disable plugins, but you may lose some settings when you reactivate your plugins. You can also [quickly disable all plugins through phpmyadmin while retaining options](https://perishablepress.com/quickly-disable-or-enable-all-wordpress-plugins-via-the-database/).
I hope this helps you. Good luck! |

| I'm working on a custom theme. For my comment section, if the user role is administrator I want to display "Admin", if subscriber "Subscriber", etc.
The problem is, I will add this code and "Admin" shows beside all users even if not admin (I've tried changing the role, this is just an admin example):
```
if ( current_user_can( 'administrator' ) ) {
echo '<div class="admin-tag"></div>';
}
```
Here is another one I tried, did not work at all:
```
if( current_user_can( 'administrator' ) ) {
echo 'Admin';
} else if ( current_user_can( 'subscriber' ) ) {
echo 'Subscriber';
}
``` | You are passing a role name, `administrator`, to `current_user_can`. Looking at [the Codex page](https://codex.wordpress.org/Function_Reference/current_user_can) this is supported but not guaranteed to work, and should generally be avoided:
>
> Passing role names to current\_user\_can() is discouraged as this is not guaranteed to work correctly (see #22624).
>
>
>
Instead, you should use a capability:
```
if ( current_user_can( 'manage_options' ) ) {
echo 'Admin';
} else if ( current_user_can( 'edit_pages' ) ) {
echo 'Editor';
} else if ( current_user_can( 'publish_posts' ) ) {
echo 'Author';
} else if ( current_user_can( 'read' ) ) {
echo 'Subscriber';
}
```
You can find a list of capabilities and roles types [on the Codex](https://codex.wordpress.org/Roles_and_Capabilities#Capability_vs._Role_Table) as well.
**Updated** This addresses the case of looping over the users to display each user's role:
```
foreach ( $comment_users as $user_id ) {
wp23234_show_user_role( $user_id );
}
function wp23234_show_user_role( $user_id ) {
$data = get_userdata( $user_id );
$roles = $data->roles;
if ( in_array( $roles, 'administrator' ) ) {
echo 'Administrator';
} else if ( in_array( $roles, 'editor' ) ) {
echo 'Editor';
} else if ( in_array( $roles, 'author' ) ) {
echo 'Author';
} else if ( in_array ( $roles, 'subscriber' ) ) {
echo 'Subscriber';
}
}

This was assisted by the *wp-front* plugin that allows you to easily define user roles.

This new remote editor role is new and problematic as they would need to be able to see their own posts plus any posts created by other editors at the same company. They mustn’t be able to see everyone’s posts though.
Is this possible with wp-front or any other plugin or simply by some hand made solution outside of plugins ?
Ideally a solution would work by adding collections of users to groups of some kind but it doesn't have to. | Here's my approach. Bear in mind that it covers the basic needs you've described but could be easily expanded into more robust solution. Few steps to follow (all code goes to your `functions.php`):
1. Save company name as user meta
=================================
The first thing we need to do is assigning a company name to a user - i'd go with user meta to achieve that. You could add a metabox to edit user screen for easy management, I'm not including code for that here, but I'm sure you get the idea.
For testing you can just add meta to user with `update_user_meta( $user_id, 'company', 'Tyrell Corporation' );` ([codex](https://developer.wordpress.org/reference/functions/update_user_meta/))
So in this example I assume that we have a bunch of authors with `Tyrell Corporation` set as `company` user meta key and editor with exactly same meta.
2. Add Company meta to posts based on author's user meta
========================================================
To make things easier and cheaper, I'd keep the reference to Company name also in every post saved by any author with company assigned (that way we can get rid of at least one query to author meta table every time we're checking editor's rights to edit the post later on). To do that, I'm using `save_post` [hook](https://developer.wordpress.org/reference/hooks/save_post/):
```
function save_company_meta( $post_id, $post, $update ) {
// get author's company meta
$company = get_user_meta( $post->post_author, 'company', true );
if ( ! empty( $author_id ) ) {
// add meta data to the post
update_post_meta( $post_id, 'company', true );
}
}
add_action( 'save_post', 'save_company_meta', 10, 3 );
```
Now every time a user saves his/her draft, the company name that was assigned to this user is copied to post meta.
3. Map editor's edit\_post capability
=====================================
Finally we can simply [map](https://developer.wordpress.org/reference/functions/map_meta_cap/) editor's 'edit\_post' capability. If the post's `company` meta data is different than editor's `company` user meta, we take the capability to edit this particular post away from that particular editor. There are some additional conditions in the code below, for example we don't apply restrictions if the post has no `company` meta at all or is not a `post` post type. You can align that to your needs:
```
function restrict_access_to_company_posts( $caps, $cap, $user_id, $args ) {
/*
We're messing with capabilities only if 'edit_post'
is currently checked and the current user has editor role
but is not the administrator
*/
if ( ! in_array( $cap, [ 'edit_post' ], true ) ) {
return $caps;
}
if ( ! user_can( $user_id, 'editor' ) || user_can( $user_id, 'administrator' ) ) {
return $caps;
}
/*
$args[0] holds post ID. $args var is a bit enigmatic, it contains
different stuff depending on the context and there's almost
no documentation on that, you've got to trust me on this one :)
Anyways, if no post ID is set, we bail out and return default capabilities
*/
if ( empty( $args[0] ) ) {
return $caps;
}
/*
You can also make sure that you're restricting access
to posts only and not pages or other post types
*/
if ( 'post' !== get_post_type( $args[0] ) ) {
return $caps;
}
$post_company = get_post_meta( $args[0], 'company', true );
$editor_company = get_user_meta( $user_id, 'company', true );
/*
if no meta data is set or editor is assigned
to the same company as the post, we allow normal editing
*/
if ( empty( $post_company ) || $post_company === $editor_company ) {
return $caps;
}
// finally, in all other cases, we restrict access to this post
$caps = [ 'do_not_allow' ];
return $caps;
}
```
This wouldn't hide the posts completely from admin UI, you can still see them on the list, but editor cannot get into post's edit screen and change it nor see the draft (WordPress will automatically remove all "edit" links for you, also in admin bar on front-end).
Once the post is published, the Editor still wouldn't be able to edit posts content.
4. (Optionaly) Remove posts from admin list completely
=======================================================
If above still isn't enough, you can also hook into `pre_get_posts` ([codex](https://codex.wordpress.org/Plugin_API/Action_Reference/pre_get_posts)) to hide posts from admin list completely:
```
function query_company_posts_only( $query ) {
if ( ! is_admin() || empty( get_current_user_id() ) ) {
return $query;
}
$editor_company = get_user_meta( get_current_user_id(), 'company', true );
if ( empty( $editor_company ) ) {
return $query;
}
$query->set( 'meta_key', 'company' );
$query->set( 'meta_value', $editor_company );
}
add_action( 'pre_get_posts', 'query_company_posts_only', 10, 1 );
```
Hope that does the trick, just play around with it and add some improvements here and there. |

| currently I am developing a site using the Dokan multivendor plugin. I added a custom field in the registration form and
The below code is being used to add the custom field in the registration form
```
<p class="form-row form-group form-row-wide">
<label for="tskypeid"><?php _e( 'Skype ID', 'dokan-lite' ); ?> <span class="required">*</span></label>
<input type="text" class="input-text form-control" name="tskypeid" id="tskype-id" value="<?php if ( ! empty( $postdata['tskypeid'] ) ) echo esc_attr($postdata['tskypeid']); ?>" required="required" />
</p>
```
This is code that is being used to save the field data:
```
// save skype id after registration
function ms_dokan_on_create_seller( $user_id, $data ) {
if ( $data['role'] != 'seller' ) {
return;
}
$dokan_settings = array(
'tskypeid' => $_POST['tskypeid'],
);
update_user_meta( $user_id, 'dokan_profile_settings', $dokan_settings );
update_user_meta( $user_id, 'dokan_store_name', $dokan_settings['store_name'] );
do_action( 'dokan_new_seller_created', $user_id, $dokan_settings );
}
add_action( 'woocommerce_created_customer', 'ms_dokan_on_create_seller', 10, 2);
```
tried to access the value using the below code:
```
function wc_vendors_name_loop( $store_id ) {
$user_id = get_current_user_id();
$dokan_profile_settings = get_user_meta( $user_id )
['dokan_profile_settings'];
echo "<pre>";
var_dump( $dokan_profile_settings );
echo "</pre>";
}
add_action( 'wp_footer', 'wc_vendors_name_loop' );

Thank you in advance. | If you're asking how to get those meta keys via WordPress, you can use the `get_user_meta()` - <https://codex.wordpress.org/Function_Reference/get_user_meta>
`get_user_meta( $user_id, 'tskypeid', true )` |

However, if you're not reyling on the `get_header` action, you can just as well use [`get_template_part()`](https://developer.wordpress.org/reference/functions/get_template_part/), as these functions work very similar.
```
get_template_part('subdir/header', 'my');

| How can `$post_id` be used while echoing posts in single.php?
Is it a global variable? | No, `$post_id` is not a global variable. You can see a list of global variables WordPress creates here: <https://codex.wordpress.org/Global_Variables>
`$post_id` is just a common naming convention for a variable that contains a post ID. In tutorials and example code it shows that the value is expected to be a post ID, but you still need to have set its value somewhere else in the code.
If you are inside [The Loop](https://developer.wordpress.org/themes/basics/the-loop/) you can get the ID of the current page or post in the loop with `$post_id = get_the_ID()`. If you are outside The Loop and want to get the ID of the currently queried post or page you can use `$post_id = get_queried_object_id()`.
Another way you might get a post ID is in a hook callback. For example, in the [`post_thumbnail_size`](https://developer.wordpress.org/reference/hooks/post_thumbnail_size/) hook the callback receives a post ID as the 2nd argument:
```
function wpse_299132_post_thumbnail_size( $size, $post_id ) {
return $size;
}
add_filter( 'post_thumbnail_size', 'wpse_299132_post_thumbnail_size', 10, 2 );
```
But that's just the name used in the documentation to make it clear what the variable contains. You can call it anything you like. This is also valid, for example:
```
function wpse_299132_post_thumbnail_size( $size, $myPostId ) {
return $size;
}
add_filter( 'post_thumbnail_size', 'wpse_299132_post_thumbnail_size', 10, 2 );
```
`$myPostId` is the 2nd argument, so will contain a post ID. But what you call it doesn't matter. |

It's for data protection. | I don't have a ready to use solution. Howeder I think is not to heavy to build a custom plugin, that do that.
1. Update the comment data, use [`wp_update_comment()`](https://codex.wordpress.org/Function_Reference/wp_update_comment).
2. For anonymize the IP you can use [`wp_privacy_anonymize_ip()`](https://core.trac.wordpress.org/ticket/43545) *(currently not in core, open as ticket)*.
3. Use the wp cron to run this after 6 months and build a comparison with the comment date to anonymize the data of the comment.
Alternative to the wp function to anonymize the IP helps this small function, only an small idea.
```
function fb_cut_ip( $ip, $cut_end = true )
{
return str_replace(
( $cut_end ? strrchr( $ip, ':' ) : strstr( $ip, ':' ) ),
'',
$ip

| Is it possible to append `?ref=myref` to all external URLs?
If so I'm guessing I will also need to check if a `?` already exists and use `&` if so.
I'm a WP noob just coming from Joomla, any tips / help would be a very nice warm welcome. :)
Not sure if it can be done on page or `.htaccess`. | Inbound vs Outbound links:
==========================
I guess it'll be helpful to clarify these concepts:
**Inbound links** = links from another website to your own website.
**Outbound links** = links from your website to another website.
An [external link](https://moz.com/learn/seo/external-link) would be any link that points to any domain other than the domain the link exists on.
From your comments, I guess what you're trying to achieve is to modify all your outbound links.
As @MrWhite suggests, **you will not be able to change your outbound links by modifying your .htaccess file** (it would be helpful, though, if you had to modify your inbound links).
Now, a couple of solutions that can work for you:
Modify your links on the browser (using JavaScript)
===================================================
This should work (as long as JavaScript is enabled in the user's browser):
```
document.addEventListener( "DOMContentLoaded", modify_outbound_links);
function modify_outbound_links(){
anchors = document.getElementsByTagName('a');
for (let i = 0; i < anchors.length; i++) {
let p = anchors[i].href;
if (p.indexOf('yourdomain.com') === -1) {
anchors[i].href = p + (p.indexOf('?') != -1 ? "&" : "?") + 'ref=myref';
}
}
}
```
The recommended (and cleanest) option to add some JavaScript to WordPress is using [wp\_enqueue\_script](https://premium.wpmudev.org/blog/adding-scripts-and-styles-wordpress-enqueueing/). If you need an easier option, it should work if you just wrap this snippet inside `<script> ... </script>` and put it inside your footer.php.
Modify your links before they're served to the user (using WP filters)
======================================================================
You can use [WordPress filters](https://www.wpbeginner.com/glossary/filter/) (functions that are called when a specific event happens).
In your case, you can use [*'the\_content'*](https://codex.wordpress.org/Plugin_API/Filter_Reference/the_content) filter, which can be used to modify the content of the post *after it is retrieved from the database and before it is printed to the screen*.
You'd need to add this to your theme's *functions.php* file:
```
add_filter( 'the_content', 'myprefix_modify_outbound_links' );
function myprefix_modify_outbound_links( $content ) {
/* here you can search for all external links in $content and modify them as you wish */
return $content;
}
```
Note, this will filter all links in your WordPress posts. You might want to search through your theme's code, just in case there are other external links. |

``` | Rewrite rules only handle incoming requests, they aren't involved in link generation.
The primary WordPress rewrite system is parsed internally with PHP, you won't see any changes to an `.htaccess` file when you add an endpoint. The basic .htaccess rules essentially say "If this isn't a request for a physical file or directory on the server, then hand the request over to WordPress".
Your `account_url` function has to handle both "ugly" and "pretty" cases when it outputs the account URLs. We can look at the built in [`get_permalink` function](https://developer.wordpress.org/reference/functions/get_permalink/) to see how WordPress handles this, here's an abbreviated version:
```
$permalink = get_option('permalink_structure');
if ( '' != $permalink ) {
// output a pretty permalink
} else {
// output an ugly permalink
}
```
The `permalink_structure` option holds the chosen pattern if pretty permalinks are enabled, we know pretty permalinks are disabled if it's empty. |

| I'm looking to mass remove or clear the default attribute for variable products in Woocommerce.
[](https://i.stack.imgur.com/BdWNd.png)
Is there an easy way to mass clear this value? If not, would you be able to direct me on where I can find this value in phpMyAdmin? | Default attributes of WooCommerce variable products are stored as post meta in the database.
You can find them in the `wp_postmeta` table, where the `post_id` column is the post ID of the parent product (Variable product), and the `meta_key` column is `_default_attributes`.
You can clear and remove default attributes of all products by replacing all non-empty arrays.
To do so, open phpMyAdmin and select the database of your WordPress installation from the left panel and click on SQL tab. Then write the below SQL commands and press Go:
>
> Don't forget to backing up your database before executing any command
> on phpMyAdmin
>
>

```
UPDATE `wp_postmeta` SET `meta_value`= 'a:0:{}' WHERE meta_key = '_default_attributes'

Or do I need to create custom-template for page and display custom post types there. | The simple answer is “yes, you can”, but I’m pretty sure it won’t satisfy you ;)
So... How can you achieve this and show only custom posts on home.php? All you need is to use pre\_get\_posts hook like so:
```
add_action( 'pre_get_posts', 'add_custom_post_types_to_home_query' );
function add_custom_post_types_to_home_query( $query ) {
if ( is_home() && $query->is_main_query() )
$query->set( 'post_type', array( 'book', 'movie' ) );
return $query;
}
```
The code above will change the main query so it shows only books and movies. |

| Is it possible to use wp\_remote\_post to send http post requests to 3rd party api's? I wasn't able to successfully save the user object as a javascript variable, so I was hoping I could make an http request with php and handle the javascript manipulation in my node express app.
Current attempt:
```
function identify_user() {
echo "made it into identify user";
if( is_user_logged_in()):
$current_user = wp_get_current_user();
$user = [];
$user['id'] = $current_user->ID;
$user['user_login'] = $current_user->user_login;
$user['user_email'] = $current_user->user_email;
$user['user_firstname'] = $current_user->user_firstname;
$user['user_lastname'] = $current_user->user_lastname;
$user['display_name'] = $current_user->display_name;
$response = wp_remote_post( 'myapp.com/endpoint', array(
'method' => 'POST',
'headers' => array('Content-Type' => 'application/json; charset=utf-8'),
'body' => json_encode($user)
)
);
if ( is_wp_error( $response ) ) {
$error_message = $response->get_error_message();
echo "Something went wrong: $error_message";
} else {
print_r( $response );
}
endif;
}
add_action( 'wp_login', 'identify_user' );
```
I'm having trouble troubleshooting this code because none of my echo calls are logging to the console. I've seen that you can run error\_log(something) but haven't been able to get that working either. | The 'body' needs to be an array, not including the 'json\_encode($user)' piece.
```
$response = wp_remote_post( 'myapp.com/endpoint', array(
'method' => 'POST',
'headers' => array('Content-Type' => 'application/json; charset=utf-8'),
'body' => $user
)
);
```
I have this in my function since I also had issues with the body being an object:
```
if (is_object($user) && !is_array($user))
$user = json_decode(json_encode($user), true);
$body = $user;
```
Regarding the 'run error\_log(something) ...' that you are having problems with, try
[#David Lee's wrapper function](https://wordpress.stackexchange.com/questions/260236/how-to-put-logs-in-wordpress)
Basically you can call
```
write_log('THIS IS THE START OF MY CUSTOM DEBUG');
// or log data like objects
write_log($object_you_want_to_log);
```
I don't know what I would do without it. |
299,521 | <p>I am new to Wordpress development and am tired of fighting with Contact form 7 to style it how I would like.

| I have a few years worth of experience building [Child Themes](https://developer.wordpress.org/themes/advanced-topics/child-themes/) in WordPress, which is generally my preferred route when developing a new website as I am not a theme developer per say.
I am now doing a couple of projects which want to leverage the WP REST API, and I am looking to use the [Foxhound](https://github.com/ryelle/Foxhound) theme, built using React js, as a parent theme.
Beyond the page template/css overloading approach to child theme-ing, I have been trying to understand how to extend the parent theme's default react app functionality to customise my child theme js functionality. I understand how to [add custom fields](https://developer.wordpress.org/rest-api/extending-the-rest-api/modifying-responses/#adding-custom-fields-to-api-responses) to existing end-points, however, what I am not able to understand is how to load [custom react components](https://www.tutorialspoint.com/reactjs/reactjs_component_life_cycle.htm). Should I/Can I build a [custom react app](https://github.com/facebook/create-react-app) to load from my child theme? If so how can I ensure it executes after the parent theme app? | This is my very simple implementation of contact form:

| This is not really a question but a guide on how to make authenticated requests to the Wordpress API using JWT. I'm writing this as a reminder to myself and for those who may need some help with the same topic. | **Why JWT authentication**
I'm building a site that uses Wordpress as the back-end, and a React+Redux app as the front-end, so I'm pulling all the content in the front-end by making requests to the Wordpress API. Some requests (mainly, POST requests) must be authenticated, which is when I came across JWT.
**What we need**
To use JWT authentication with Wordpress, we first need to install the [JWT Authentication for WP REST API](https://it.wordpress.org/plugins/jwt-authentication-for-wp-rest-api/) plugin. As is explained in the plugin's instructions, we also need to modify some core Wordpress files. In particular:
In the .htaccess file included in the Wordpress installation's root folder, we need to add the following lines:
```
RewriteEngine on
RewriteCond %{HTTP:Authorization} ^(.*)
RewriteRule ^(.*) - [E=HTTP_AUTHORIZATION:%1]
```
In the wp-config.php file, also included in the Wordpress installation's root folder, we need to add these lines:
```
define('JWT_AUTH_SECRET_KEY', 'your-top-secret-key'); // Replace 'your-top-secret-key' with an actual secret key.
define('JWT_AUTH_CORS_ENABLE', true);
```
**Testing to see if JWT is available**
To verify that we can now use JWT, fire up Postman and make a request to the Wordpress API's default 'index':
```
http://example.com/wp-json/
```
A few new endpoints, like `/jwt-auth/v1` and `/jwt-auth/v1/token` should have been added to the API. If you can find them in the response to the above request, it means JWT is now available.
**Getting the JWT token**
Let's stay in Postman for the moment, and let's request a token to the Wordpress API:
```
http://example.com/wp-json/jwt-auth/v1/token
```
The response will contain the JWT token, which is an encrypted key that looks something like this:
>
> eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpc3MiOiJodHRwOlwvXC9sb2NhbGhvc3Q6ODg4OFwvZm90b3Jvb20tbmV4dCIsImlhdCI6MTUyMjU5NzQ1MiwibmJmIjoxNTIyNTk3NDUyLCJleHAiOjE1MjMyMDIyNTIsImRhdGEiOnsidXNlciI6eyJpZCI6IjEifX19.hxaaT9iowAX1Xf8RUM42OwbP7QgRNxux8eTtKhWvEUM
>
>
>
**Making an authenticated request**
Let's try to change the title of a post with an ID of 300 as an example of an authenticated request with JWT.
In Postman, choose POST as the method and type the following endpoint:
```
http://example.com/wp-json/wp/v2/posts/300
```
Choose No Auth in the Authorization tab, and add the following in the Headers tab:
```
'Content-type': 'application/json',
'Authorization': 'Bearer jwtToken' // Replace jwtToken with the actual token (the encrypted key above)
```
Finally, in the Body tab, select the raw and JSON (application/json) options, then in the editor right below the options type the following:
```
{ "title": "YES! Authenticated requests with JWT work" }
```
Now you can hit SEND. Look in the response tab with all the data about the post that we requested: the value for the title key should now be `YES! Authenticated requests with JWT work` |

define('JWT_AUTH_SECRET_KEY', 'your-top-secret-key'); // Replace 'your-top-secret-key' with an actual secret key.
define('JWT_AUTH_CORS_ENABLE', true);
```
**Testing to see if JWT is available**
To verify that we can now use JWT, fire up Postman and make a request to the Wordpress API's default 'index':
```
http://example.com/wp-json/
```
A few new endpoints, like `/jwt-auth/v1` and `/jwt-auth/v1/token` should have been added to the API. If you can find them in the response to the above request, it means JWT is now available.
**Getting the JWT token**
Let's stay in Postman for the moment, and let's request a token to the Wordpress API:
```
http://example.com/wp-json/jwt-auth/v1/token
```
The response will contain the JWT token, which is an encrypted key that looks something like this:

**Making an authenticated request**
Let's try to change the title of a post with an ID of 300 as an example of an authenticated request with JWT.
In Postman, choose POST as the method and type the following endpoint:
```
http://example.com/wp-json/wp/v2/posts/300
```
Choose No Auth in the Authorization tab, and add the following in the Headers tab:
```
'Content-type': 'application/json',
'Authorization': 'Bearer jwtToken' // Replace jwtToken with the actual token (the encrypted key above)
```
Finally, in the Body tab, select the raw and JSON (application/json) options, then in the editor right below the options type the following:
```
{ "title": "YES! Authenticated requests with JWT work" }
```
Now you can hit SEND. Look in the response tab with all the data about the post that we requested: the value for the title key should now be `YES! Authenticated requests with JWT work` |
