</code></pre>
<p>The problem is, I can't get the image URLs. My code:</p>
<pre><code> <?php $ppics = get_post_meta( get_the_ID(), 'shop_demosc', false );
$ppurl = wp_get_attachment_url($ppics);
foreach ($ppics as $key => $ppurl){

I have a post meta for image uploads which allows a maximum of 5 files.
The data is stored in like this:
```
a:5:{i:0;s:3:"694";i:1;s:3:"694";i:2;s:3:"697";i:3;s:3:"695";i:4;s:3:"696";}
```
The problem is, I can't get the image URLs. My code:
```
<?php $ppics = get_post_meta( get_the_ID(), 'shop_demosc', false );
$ppurl = wp_get_attachment_url($ppics);
foreach ($ppics as $key => $ppurl){
echo '<img src="'. print_r($ppurl) .'">';
} ?>
```
This code returns:
```
Array
(
[0] => 694
[1] => 694
[2] => 697
[3] => 695
[4] => 696
)
```
whats wrong? How can I get the URLs to the 5 images?

Your `var_dump` looks like it's returning an array because you're passing `false` to [`get_post_meta()`](https://developer.wordpress.org/reference/functions/get_post_meta/). Also you don't want to `print_r()` on an `echo` line.

```
<?php
$ppics = get_post_meta( get_the_ID(), 'shop_demosc', true );
// if the value is an array of an array, just set to the first array
if( is_array($ppics) && count($ppics) === 1 && is_array($ppics[0]) ){
$ppics = $ppics[0];
}
foreach ( $ppics as $key => $attachment_id ) {
$image_url = wp_get_attachment_url( $attachment_id );
printf( '<img src="%s">', $image_url );
}
?>

Use [WP-CLI's](https://wp-cli.org/) - `wp core install` - Runs the standard WordPress installation process.

First you have to passed two additional arguments into the register\_post\_type() function.
1. capability\_type
2. map\_meta\_cap
Then, You can add capability using [add\_cap();](https://codex.wordpress.org/Function_Reference/add_cap) function.
```
register_post_type( 'acme_product',
array(
'labels' => array(
'name' => __( 'Products' ),
'singular_name' => __( 'Product' )
),
'public' => true,
'has_archive' => true,
'capability_type' => array('acme_product','acme_products'),
'map_meta_cap' => true,
)
);
add_action('admin_init','vendor_role_caps');
function vendor_role_caps() {
$role = get_role('vendor_user');
$role->add_cap( 'read' );
$role->add_cap( 'read_acme_product');
$role->add_cap( 'read_private_acme_products' );
$role->add_cap( 'edit_acme_product' );

<p>My code was checked and seems OK so maybe the problem lies in the <code>htaccess</code> file whose content on my online server is:</p>
<pre><code>SetEnv PHP_VER 5_4
Options -Indexes
ErrorDocument 404 /index.php
RewriteEngine on
RewriteCond %{HTTP_HOST} !^www.example.fr$
RewriteRule ^(.*) http://www.example.fr/$1 [QSA,L,R=301]
</code></pre>
<p>Any reason why this <code>htaccess</code> would prevent forms from submitting correctly on my site?</p>

<input type='hidden' name='sub' value='1'>

</form>
</code></pre>
<p>PHP (I know the syntax is ugly, I'll improve that):</p>
<pre><code>if ( isset($_POST['sub']) ) $sub = $_POST['sub']; else $sub = '';

My code was checked and seems OK so maybe the problem lies in the `htaccess` file whose content on my online server is:
```
SetEnv PHP_VER 5_4
Options -Indexes
ErrorDocument 404 /index.php
RewriteEngine on
RewriteCond %{HTTP_HOST} !^www.example.fr$
RewriteRule ^(.*) http://www.example.fr/$1 [QSA,L,R=301]
```
Any reason why this `htaccess` would prevent forms from submitting correctly on my site?
Just in case here's my code:
```
<form id='contact_form_mmt' action='<?php echo bloginfo("wpurl"); ?>/contact' method='post'>
<input type='text' name='contact_nom' placeholder='Votre nom *' data-validation='length' data-validation-length='min3' data-validation-error-msg='<?php echo $text_too_short_or_empty; ?>'>
<input type='text' name='contact_prenom' placeholder='Votre prénom *' data-validation='length' data-validation-length='min3' data-validation-error-msg='<?php echo $text_too_short_or_empty; ?>'>
<input type='text' name='contact_mail' placeholder='Votre mail *' data-validation='email' data-validation-length='min3' data-validation-error-msg='<?php echo $email_valid; ?>'>
<select name='contact_destinataire'>
<option value="[email protected]|Information générales">Information générales</option>
<option value="[email protected]|Problèmes liés au site">Problèmes liés au site</option>
</select>
<textarea name='contact_message' placeholder='Message *'data-validation='length' data-validation-length='min3' data-validation-error-msg='<?php echo $text_too_short_or_empty; ?>'></textarea>
<input type='hidden' name='sub' value='1'>
<input type='submit' value='envoyer'>
</form>
```
PHP (I know the syntax is ugly, I'll improve that):
```
if ( isset($_POST['sub']) ) $sub = $_POST['sub']; else $sub = '';
if ( isset($_POST['contact_nom']) ) $contact_nom = $_POST['contact_nom']; else $contact_nom = '';
if ( isset($_POST['contact_prenom']) ) $contact_prenom = $_POST['contact_prenom' ]; else $contact_prenom = '';
if ( isset($_POST['contact_mail']) ) $contact_mail = $_POST['contact_mail']; else $contact_mail = '';
if ( isset($_POST['contact_sujet']) ) $contact_sujet = $_POST['contact_sujet']; else $contact_sujet = '';
if ( isset($_POST['contact_destinataire']) ) $contact_destinataire = $_POST['contact_destinataire']; else $contact_destinataire = '';
if ( isset($_POST['contact_message']) ) $contact_message = $_POST['contact_message']; else $contact_message = '';
```

The best way to deal with Form Posts in Wordpress is to use a special endpoint, **/wp-admin/admin-post.php**.
POST data can be messed up, both by the WP Query call, and by any redirects that happen.
So you set up your form with this action:
```
<form action="<?= admin_url('admin-post.php') ?>" method="post">
<input type="hidden" name="action" value="special_action">
<?php wp_nonce_field('special_action_nonce', 'special_action_nonce'); ?>
```
Then you can handle the form by adding an action to your theme or plugin:
```
add_action('admin_post_nopriv_special_action', ['My\Plugins\FormController', 'specialAction']);
add_action('admin_post_special_action', ['My\Plugins\FormController', 'specialAction']);
```
Note that Wordpress constructs a special action, based on the **action** value in the form, **admin\_post\_no\_priv\_*special\_action*** (if you're logged out) and **admin\_post\_*special\_action*** (if you're logged in). You can point these in different locations.
These action endpoints will always have access to POST, and will never trigger a redirect (which is often what Wordpress does for pretty routes... it often routes: *site.com/about* to *site.com/?pageName=about*).
Once you've handled the form as you want, you can do a **wp\_redirect()** to get to where you need it to be. This is also helpful because an accidental page refresh will not re-send the form.

<p>I wanted to filter the blog title displayed in the header to apply different CSS styles to different title parts/words, so I added the below function to my (WP 4.7) Twenty Seventeen child theme's <em>functions.php</em> and this worked very well. The problem is that this function added the CSS code also to the meta title displayed in the title bar. How to repair this?</p>
<pre><code>/** Format the site title parts **/
add_filter( 'bloginfo', 'format_site_title_parts', 10, 2 );
function format_site_title_parts( $text, $show ){

<p>Looking at <a href="https://developer.wordpress.org/reference/functions/get_post_meta/" rel="noreferrer"><code>get_post_meta()</code></a> I always have to remember to set the <code>$single</code> param to <code>true</code>. I generally assume I'm setting a value and I expect to get that value back.</p>
<blockquote>
<p>Retrieve post meta field for a post.</p>
<ul>
<li><strong>$post_id</strong> <em>(int) (Required)</em> Post ID.</li>
<li><strong>$key</strong> <em>(string) (Optional)</em> The meta key to retrieve. By default, returns data for all keys. Default value: ''</li>
<li><strong>$single</strong> <em>(bool) (Optional)</em> Whether to return a single value. Default value: false</li>
</ul>
</blockquote>
<p>I know this should exist as an option for a reason but I don't personally know why that is. Can someone explain why this returns an <code>array</code> of values by default? It makes sense from a backwards compatibility standpoint but have things evolved? Or are there Core features that require it to be this way for an efficiency that I am unaware of.</p>
<p>Does adding <code>$prev_value</code> to <a href="https://codex.wordpress.org/Function_Reference/update_post_meta" rel="noreferrer"><code>update_post_meta()</code></a> create a history as array elements?</p>
<p>I would appreciate a <strong>working</strong> example of when this, being set to <code>false</code>, makes sense. That means code I can test. In addition to, a genuinely well thought out and researched answer. That means I want comments like TLC wants scrubs. </p>

It can be easily understood if you use multple key-value pairs of data in one field row, that is, you use an array or a object with one meta key.</p>\n\n<p>Imaging a car as the object. You can set multiple meta values to describe the car, for example <code>color</code> and <code>fuel</code>. You can serialize the data and store it in one meta field (only one meta key):</p>\n\n<pre><code>$metadata = array(\n 'color' => 'white',\n 'fuel' => 'diesel'\n);\n// as it is an array, $metadata will be serialized automatically by WordPRess\nupdate_post_meta( 458, 'car_meta', $metadata );\n</code></pre>\n\n<p>In this example, you can use <code>get_post_meta()</code> with the third parameter set to <code>false</code>;</p>\n\n<pre><code>$carmeta = get_post_meta( 458, 'car_meta', false );\n// Serialized meta is unserialized automatically by WordPress\necho $carmeta[0]['color'];\necho $carmeta[0]['fuel'];\n</code></pre>\n\n<p>Or you can use it with <code>true</code>, it is not a big difference:</p>\n\n<pre><code>$carmeta = get_post_meta( 458, 'car_meta', true );\necho $carmeta['color'];\necho $carmeta['fuel'];\n</code></pre>\n\n<p>Now imaging you want to get only red cars thar run diesel. You would need to get <strong>all cars</strong> and their meta data from database, and loop over all cars, unserialize the meta data and search the white cars that run diesel.

Looking at [`get_post_meta()`](https://developer.wordpress.org/reference/functions/get_post_meta/) I always have to remember to set the `$single` param to `true`. I generally assume I'm setting a value and I expect to get that value back.

> Retrieve post meta field for a post.

> * **$post\_id** *(int) (Required)* Post ID.
> * **$key** *(string) (Optional)* The meta key to retrieve. By default, returns data for all keys. Default value: ''
> * **$single** *(bool) (Optional)* Whether to return a single value. Default value: false
>

I know this should exist as an option for a reason but I don't personally know why that is. Can someone explain why this returns an `array` of values by default? It makes sense from a backwards compatibility standpoint but have things evolved? Or are there Core features that require it to be this way for an efficiency that I am unaware of.
Does adding `$prev_value` to [`update_post_meta()`](https://codex.wordpress.org/Function_Reference/update_post_meta) create a history as array elements?
I would appreciate a **working** example of when this, being set to `false`, makes sense. That means code I can test. In addition to, a genuinely well thought out and researched answer. That means I want comments like TLC wants scrubs.

In general, **storing PHP serialized data in database in a bad idea**. It can be easily understood if you use multple key-value pairs of data in one field row, that is, you use an array or a object with one meta key.
Imaging a car as the object. You can set multiple meta values to describe the car, for example `color` and `fuel`. You can serialize the data and store it in one meta field (only one meta key):
```
$metadata = array(
'color' => 'white',
'fuel' => 'diesel'
);
// as it is an array, $metadata will be serialized automatically by WordPRess
update_post_meta( 458, 'car_meta', $metadata );
```
In this example, you can use `get_post_meta()` with the third parameter set to `false`;
```
$carmeta = get_post_meta( 458, 'car_meta', false );
// Serialized meta is unserialized automatically by WordPress
echo $carmeta[0]['color'];
echo $carmeta[0]['fuel'];
```
Or you can use it with `true`, it is not a big difference:
```
$carmeta = get_post_meta( 458, 'car_meta', true );
echo $carmeta['color'];
echo $carmeta['fuel'];
```
Now imaging you want to get only red cars thar run diesel. You would need to get **all cars** and their meta data from database, and loop over all cars, unserialize the meta data and search the white cars that run diesel. This is **really bad**.
On the other hand, if you use a meta key for each meta data, for example:
```
$metadata = array(
'car_color' => 'white',
'car_fuel' => 'diesel'
);
foreach( $metadata as $key => $value ) {
update_post_meta( 458, $key, $value );
}
```
then you can get what you are looking for directly from database:
```
$args = array(
'meta_query' => array(
'relation' => 'AND',
array(
'key' => 'car_color',
'value' => 'red'
),
array(
'key' => 'car_fuel',
'value' => 'diesel'
)
)
);
$query = new WP_Query( $args );
```
Now imaging that a car can be **available in multiple colors**, you could do this:
```
$metadata = array(
'car_colors' => array( 'red', 'white' ),
'car_fuel' => 'diesel'
);
foreach( $metadata as $key => $value ) {
update_post_meta( 458, $key, $value );
}
```
Now we have `car_colors` meta key with a serialized array. We face the same problems described before if we want to query only for cars available in one color. So, it is better to store colors as repeater meta field:
```
$metadata = array(
'car_colors' => array( 'red', 'white' ),
'car_fuel' => 'diesel'
);
foreach( $metadata as $key => $value ) {
if( is_array( $value ) ) {
foreach( $value as $val ) {
// We add multiiple meta fields with the same meta key
add_post_meta( 458, $key, $val );
}
} else {
update_post_meta( 458, $key, $value );
}
}
```
Now, if you want to get all available colors of a car, you need the **third parameter of `get_post_meta()` set to `false`**, if you set it to `true` you will get only the first available color found in database for that car.
```
// This gets only the first car_colors entry found in database for car 458
$available_colors = get_post_meta( 458, 'car_colors', true );
// This gets all the car_colors entries for car 458
$available_colors = get_post_meta( 458, 'car_colors', false );
```
It is very basic example but I think it illustrates a **use case where third parameter of `get_post_meta()` makes sense**, so I hope this answers your question.
Another example could be the one exposed in other answer about shows that are performed several times within a day, for example a movie in a cinema. You want "starting times" to be a repeater field, not one field with all the starting times stored as serialized data.
About the other quesiotn: Does adding `$prev_value` to `update_post_meta()` create a history as array elements? No. If you pass `$prev_value` to `update_post_meta()`, only the existent row in database with that value will be updated; if `$pre_value` is not set, all rows for the meta key will be updated.
Finally, if you want to delete all available colors of a car:
```
delete_post_meta( 458, 'car_colors' );
```
And if you want to delete only one entry with a specific value:
```
delete_post_meta( 458, 'car_colors', 'white' );
```

You need to set the `offset` in the query.
To get the right offset value, you will need to store and send back the offset value to your ajax script (`data-offset` in the input or an hidden field).
```
$args = array(
'posts_per_page'=> 10,
'post_status'=> 'publish',
'offset'=> $_POST['offset']
);
```
`$_POST['offset']` is coming from your button with a js script.

<p>I was developing a new WordPress website so i added this function at the end of the "functions.php" file to redirect all users to a /maintenance-mode page in my website except me(My IP-Address):</p>
<pre><code>function wp_maintenance_mode() {
if ( !is_page( 2075 ) && $_SERVER['REMOTE_ADDR'] != "111.222.33.44" ) {
wp_redirect( home_url( 'maintenance-mode' ) );
exit;
}
}
add_action( 'template_redirect', 'wp_maintenance_mode' );
</code></pre>

I was developing a new WordPress website so i added this function at the end of the "functions.php" file to redirect all users to a /maintenance-mode page in my website except me(My IP-Address):
```
function wp_maintenance_mode() {
if ( !is_page( 2075 ) && $_SERVER['REMOTE_ADDR'] != "111.222.33.44" ) {
wp_redirect( home_url( 'maintenance-mode' ) );
exit;
}
}
add_action( 'template_redirect', 'wp_maintenance_mode' );
```
After finishing the website development and i wanted to put it alive i have commented this function by putting it inside comments /\* \*/ .. When i now access the website strangely the maintenance-mode still appears when i access any page. I tried to remove the comments but it still goes to the maintenance-mode page!
It is getting me crazy and i can't find why this happens. I searched everywhere, in the database, in my files for an access to the maintenance-mode page but i can't see any.

is other solution available, instead of `$GLOBALS['post']` ?
|
Do not rely on globals like `get_the_ID()` or `get_post()` do. Use the parameters for your callbacks.
You get the current post object **twice**:
1. When you register the metabox, you get the post object as a second parameter.
2. When your output callback is called, you get it as the first parameter.
Here is an example showing both cases:
```
add_action( 'add_meta_boxes', function( $post_type, \WP_Post $post ) {
add_meta_box(
'test', // handle
'Box title', // title
function( \WP_Post $post ) { // output
print get_the_title( $post );
});
});
```

One call to `get_post_meta()` fetches all met keys and values for that post. All these values are then stored in the cache. The next call will just fetch the data from the cache. So you can safely call that function multiple times.
In details:
1. `get_post_meta()` calls `get_metadata('post', $post_id, $key, $single);`
2. `get_metadata()` checks the cache and calls `update_meta_cache()` if it doesn't find an existing cache.
3. `update_meta_cache()` fetches all entries with:
```
"SELECT $column, meta_key, meta_value
FROM $table
WHERE $column IN ($id_list)
ORDER BY $id_column ASC"
```
The same is true for user meta values.

It is possible to pass an array with allowed protocols to the [esc\_url()](https://developer.wordpress.org/reference/functions/esc_url/) function. For data-URLs this has to contain the `data` scheme, as this is not whitelisted by [wp\_allowed\_protocols()](https://developer.wordpress.org/reference/functions/wp_allowed_protocols/) as default.
```
esc_url( $data_url, array( 'data' ) );

Take a look at [`current_time()`](https://codex.wordpress.org/Function_Reference/current_time).
>
> Returns the blog's current local time in the specified format. There are two named formats: 'mysql' for MySQL/MariaDB's timestamp data type format (i.e. YYYY-MM-DD HH:MM:SS), and 'timestamp' for the Unix timestamp format (i.e. epoch). Other strings will be interpreted as PHP date formats (e.g. 'Y-m-d') since 3.9.0. The optional secondary parameter can be used to retrieve GMT time instead of the blog's local time.
>
>
> The local time returned is based on the timezone set on the blog's General Settings page, which is UTC by default.
>
>
> `current_time( 'timestamp' )` should be used in lieu of `time()` to return the blog's local time. In WordPress, PHP's `time()` will always return **UTC** and is the same as calling `current_time( 'timestamp', true )`.
>
>
>
You can also modify the [`TimeZone`](http://php.net/manual/en/class.datetimezone.php) of a [`date`](http://php.net/manual/en/function.date.php).
```
$d = date( 'c', time() );
echo $d; // 2016-06-12T16:35:39+00:00
$t = new DateTime($d);
$t->setTimezone(new DateTimeZone( 'America/Los_Angeles' ));
echo "\tLOS\t" . $t->format( 'g:i:s A' ); // 9:35:39 AM
$t->setTimezone(new DateTimeZone( 'America/New_York' ));
echo "\tNYC\t" . $t->format( 'g:i:s A' ); // 12:35:39 PM
echo ( $t->format('G') < 9) ? ' Before 9AM' : ' After 9AM';
```

Never, **never** re-query a native archive - use the [`pre_get_posts` hook](https://codex.wordpress.org/Plugin_API/Action_Reference/pre_get_posts) to *alter* the main query:
```
add_action( 'pre_get_posts', function ( $wp_query ) {
if ( $wp_query->is_main_query() && $wp_query->is_author() ) {
$paged = max( 1, ( int ) $wp_query->get( 'paged' ) );
if ( $paged === 1 ) {
$wp_query->set( 'posts_per_page', 10 );
} else {
$wp_query->set( 'posts_per_page', 9 );
$wp_query->set( 'offset', ( ( $paged - 1 ) * 9 ) + 1 );
}
}
});
```
Add the above to your `functions.php` and remove `query_posts( ... )` line.

<p>When I enqueue Bootstrap with <code>wp_enqueue_style()</code>, Bootstrap is loaded after the child theme's <code>style.css</code> and will override <code>style.css</code>.
One way to load <code>style.css</code> after Bootstrap is to enqueue <code>style.css</code> as well, but this will cause it to be loaded twice.
Any idea how to enqueue <code>style.css</code> once AND after Bootstrap?
Thanks!</p>

Mostly the parent theme might be enqueing the child theme's `style.css`, if so you can dequeue it by using handle and then enqueue with proper dependency.
If the child theme's handle is `child-theme-style`, then dequeue it using
`wp_dequeue_style('child-theme-style')`
then enqueue it as needed like so.
```
wp_enqueue_style('child-theme-dep',get_stylesheet_uri(),array('bootstrap-handle-here'))
```
[](https://i.stack.imgur.com/JCwUa.png)
We can easily know the child theme stylesheet url by looking at the link output in the head, for example in the attached image.
```
<link rel='stylesheet' id='hybrid-style-css' href='https://wptavern.com/wp-content/themes/stargazer-child-dev/style.css?ver=4.6.1' type='text/css' media='all' />
```
Tells us that the child theme's enqueue handle is `hybrid-style` which is the *`id`* without `-css`.

`$page = get_page_by_title($title)` - this line is failing somewhere, so you should do a check on this to make sure it exists.

I have a strange issue that i don't really understand, I explain :
In my `tag.php`, i have an infinite scroll with custom post types thanks to the active tag and ajax.
```
$posts = get_posts( array(
'post_type' => 'video',
'posts_per_page' => 6,
'paged' => 1,
'post_status' => 'publish',
'post__not_in' => $posts_not_in,
'tax_query' => array(
array(
'taxonomy' => 'post_tag',
'field' => 'id',
'terms' => $theme->term_id,
'operator' => 'IN'
)
)
)) ;
```
I do the same get\_posts in `functions.php` in my ajax function
```
add_action( 'wp_ajax_get_posts_theme', 'get_posts_theme' );
add_action( 'wp_ajax_nopriv_get_posts_theme', 'get_posts_theme' );
function get_posts_theme() { ... }
```
and it displays differents posts results. Why ? Any ideas ? Thanks for help me.

This will definitely work....It worked for me...
```php
$username = get_the_author_meta( 'login', $author_id );
$args = array(
'post_type' => 'any',
'orderby' => 'date',
'order' => 'DESC',
'suppress_filters' => true,
'tax_query' => array(
array(
'taxonomy' => 'author',
'field' => 'name',
'terms' => $username
)
)
);
$query = new WP_Query( $args );
```

<p>I have installed a compressing plugin (<a href="https://wordpress.org/plugins/tiny-compress-images/" rel="nofollow noreferrer">https://wordpress.org/plugins/tiny-compress-images/</a>) in Wordpress to minimize the file size of all the images that I upload. Works really well, the only problem is the following:</p>
<p>If I create a new page, insert a picture and resize it manually in the editor Wordpress seems to create a new version of the picture with exactly the resolution that I have chosen. For instance I have a newly created file called airline-768x447.png in my uploads folder that was apparently created by Wordpress when I resized the original image in the editor to this size.</p>
<p>The problem is that this newly created file doesn't get compressed by the plugin and therefore its file size is way bigger than it should be.</p>
<p>Why isn't wordpress just using the original file and just resizes it using css or the width and height attributes? Is there any option to turn off this behavior where Wordpress seems to create images with individual size?</p>
<p>I have searched for quite a while but couldn't find any solutions. Thanks :)</p>

The screenshot states the problem clearly:
```
Maximum execution time of 60 seconds exceeded
```
Pages have a time limit inside which they need to do their work, otherwise a badly written PHP script could run forever.
This is why importing huge data sets runs into this problem. The bigger the import, the longer it takes, but your server only allows 60 seconds to do this in. You could bump up the limit but that will cause other issues and this might not be possible with your host. Some of the largest imports I've seen can take days
Instead, for anything but the smallest imports:
* Split your export into chunks, multiple files at 5MB each, use the WP CLI exporter to do this
* Import via WP CLI, there is no time limit for terminal commands
However for a hosting company, unless you can get access to WP CLI, doing what you're doing now will not work and there are no workarounds to make the browser importer screen work with medium to large imports. You may even struggle with small imports if it's shared hosting, and the results will be unreliable. What might work now may fail in a minutes time as the server gets busier and pages load slower

I have an existing for loop, which is necessary for the design and layout. Inside this for loop I need show post by post.
This is my code.
```
<?php for($i=$val;$i<=$cdn;$i++) { ?>
<div class="desc dsc<?php echo $dsc++; ?>" style="display: none">
<div class="team-details">
<div class="name">
<?php echo get_the_title();?><span><?php the_field('designation'); ?></span>
</div>
<?php get_template_part( 'post', 'content'); ?>
</div>
</div>
<?php } ?>

If you're looking to get the post id to say add it to a div use the\_ID()
```
<div id="post-<?php the_ID(); ?>">

Actually, the condition is always returning false because you are not passing the post id to the function [`has_post_thumbnail()`](https://developer.wordpress.org/reference/functions/has_post_thumbnail/) and the function always getting the default value which is `null`.
`has_post_thumbnail( $recent["ID"] )`.
Same with the function [`get_the_post_thumbnail()`](https://developer.wordpress.org/reference/functions/get_the_post_thumbnail/).
`get_the_post_thumbnail( $recent["ID"] )`.
```
$args = array( 'numberposts' => '3' );
$recent_posts = wp_get_recent_posts($args);
foreach( $recent_posts as $recent ){
if ( has_post_thumbnail( $recent["ID"]) ) {
echo get_the_post_thumbnail($recent["ID"],'thumbnail');
}
}
```
But if you use the functions `has_post_thumbnail();` and `get_the_post_thumbnail()` inside the WordPress [`The_Loop`](https://codex.wordpress.org/The_Loop) then you don't need to pass the post id.
```
$args = array( 'posts_per_page' => '3' );
$recent_posts = new WP_Query($args);
while( $recent_posts->have_posts() ) {
$recent_posts->the_post() ;
if ( has_post_thumbnail() ) {
echo get_the_post_thumbnail();
}
}
wp_reset_postdata();
```

I'd like to remove the "Powered by Wordpress" custom link in the footer.
I want to do this using action hooks/filters in the child theme's `function.php` file.
I don't want to use CSS (which just hides it), edit the original theme file (which will get overriden when the theme updates), or copy the `footer.php` file to the child theme and edit it out there (since I will then have to update the file after a theme update).
The theme I'm using is 'sparkling'. The footer info function is defined in the `extras.php` file:
```
function sparkling_footer_info() {
global $sparkling_footer_info;
printf( esc_html__( 'Theme by %1$s Powered by %2$s', 'sparkling' ) , '<a href="http://colorlib.com/" target="_blank">Colorlib</a>', '<a href="http://wordpress.org/" target="_blank">WordPress</a>');
}
```
And called in the footer.php file (a few lines from the bottom):
```
<div id="footer-area">
<div class="container footer-inner">
<div class="row">
<?php get_sidebar( 'footer' ); ?>
</div>
</div>
<footer id="colophon" class="site-footer" role="contentinfo">
<div class="site-info container">
<div class="row">
<?php if( of_get_option('footer_social') ) sparkling_social_icons(); ?>
<nav role="navigation" class="col-md-6">
<?php sparkling_footer_links(); ?>
</nav>
<div class="copyright col-md-6">
<?php echo of_get_option( 'custom_footer_text', 'sparkling' ); ?>
<?php sparkling_footer_info(); ?>
</div>
</div>
</div><!-- .site-info -->
<div class="scroll-to-top"><i class="fa fa-angle-up"></i></div><!-- .scroll-to-top -->
</footer><!-- #colophon -->
</div>
```
I tried inserting the following into the child's `function.php` (together with a few variants), but it doesn't work:
```
function remove_sparkling_footer(){
remove_action( 'wp_footer', 'sparkling_footer_info' );}
add_action( 'init', 'remove_sparkling_footer' );
```
Any help or ideas would be greatly appreciated.

As the function `sparkling_footer_info()` uses [`esc_html__()`](https://developer.wordpress.org/reference/functions/esc_html__/) and this function runs the [`esc_html`](https://developer.wordpress.org/reference/hooks/esc_html/) filter before outputting, you can intercept the output there.
```
add_filter ('esc_html', 'wpse_245817_esc_html', 100, 2 );
function wpse_245817_esc_html( $safe_text, $text ) {
if ( $safe_text == 'Theme by %1$s Powered by %2$s' ) {
return '';
}
return $safe_text;
}
```
Maybe you have to adapt the code a little for your own needs, I didn't test it either.

This is my function for redirecting using `save_post` (which doesn't work for me since I need to use a custom button):
```
function redirect_after_save_post() {
global $post;
if ( 'event' == get_post_type() ) {
$url = 'http://www.google.com';
wp_redirect( $url );
exit;
}
}
add_action( 'save_post', 'redirect_after_save_post' );
```
|
As the function `sparkling_footer_info()` uses [`esc_html__()`](https://developer.wordpress.org/reference/functions/esc_html__/) and this function runs the [`esc_html`](https://developer.wordpress.org/reference/hooks/esc_html/) filter before outputting, you can intercept the output there.
```
add_filter ('esc_html', 'wpse_245817_esc_html', 100, 2 );
function wpse_245817_esc_html( $safe_text, $text ) {
if ( $safe_text == 'Theme by %1$s Powered by %2$s' ) {
return '';
}
return $safe_text;
}
```
Maybe you have to adapt the code a little for your own needs, I didn't test it either.

WordPress loads jQuery because plugins and themes suppose it does. If you want another version of jQuery for your theme, there is a risk that plugins you may be using will not work, since (if they are maintained well) they are designed to work [with default jquery](https://wordpress.stackexchange.com/questions/244537/why-does-wordpress-use-outdated-jquery-v1-12-4/244543#244543).
That said, if you insist on using your own version of jQuery you can easily deregister it, as you found out. If you're not planning a public release of your theme you can control the consequences.
And yes, you should [enqueue styles](https://developer.wordpress.org/reference/functions/wp_enqueue_style/) as well. The reason to do this, is it allows you to set dependencies, which is important if (for instance) you would want to make a child theme and deregister the parent styles.

<p>First, i'd like to point I do this probably wrong, but this is a bit of a desperate thing and it popped in my head.</p>
<p>We are developing a site for a client, and he wants breadcrumbs. Now we downloaded a plugin that allows you to place breadcrumbs by calling the breadcrumbs_trial function. Since the theme doesn't support PHP additions, and we want to place it a dynamic spot within the page that isnt accessable easily.</p>
<p>Since the theme codeblock accepts shortcode, i thought (maybe stupid) to create run the breadcrumb in a shortcode, so I made an attempt,</p>
<pre><code>function breadcrumbs_func( $atts ){
breadcrumb_trail();
}
add_shortcode( 'breadcrumbs', 'breadcrumbs_func' );
</code></pre>
<p>Now I realise, I go offcourse in the scope of the function, and the breadcrumb_trail() function isn't defined in here. Is there a way i can run this stand alone function from another plugin in such thing?</p>
<p><strong>edit</strong></p>
<p>I made a typo, and it does run, but it just isn't displayed at the right position now... tweaking further i guess</p>

This will probably not work, or work in unexpected way. Shortcodes should **probably** be displayed only on a "post" single page. Using a shortcode in the way you want will either make the breadcrumbs not to be displayed on archive pages or have them displayed there multiple times or wrong places.
What you should do is a minimal modification to the theme. Insert a `do_action('show_bc`); at the appropriate place in the header file ("fork" it in a child theme if you use one). Then add something like `add_action('show_bc','breadcrumb_trail');` in the theme's `functions.php` or in a plugin.
As for the exact problem you have in your code, it is because shortcode handlers are supposed to return HTML, and not to output it. If the BC function do not have an option to return the HTML instead of echo-ing, you will have to do output buffering around its call.

<h1>Question</h1>
<p>What are all the files that I have to modify to get this to work?</p>
<h2>Background</h2>
<p>I have been searching stackoverflow for similar answers. Most talk about modifying something called a <code>php.ini</code> file. Which i have not been able to locate. But is that actually the case for WordPress themes?</p>
<p>I installed the Aqueduct theme. The problem I am having is that the images will now show up as thumbnails. So that is where I get the error</p>

Question
========
What are all the files that I have to modify to get this to work?
Background
----------
I have been searching stackoverflow for similar answers. Most talk about modifying something called a `php.ini` file. Which i have not been able to locate. But is that actually the case for WordPress themes?
I installed the Aqueduct theme. The problem I am having is that the images will now show up as thumbnails. So that is where I get the error
Error
-----
```
Warning: getimagesize() [function.getimagesize]: http:// wrapper is disabled in the server configuration by allow_url_fopen=0 in /nfs/c09/h01/mnt/133267/domains/lame.io/html/wp-content/themes/aqueduct/content.php on line 38
```
I opened up the file to make the edit, but I don't actually see the `allow_url_fopen=0` on line 38.
Code

```

I fixed the problem of not being able to see the thumbnails. Not sure this is the best overall long term solution, but it works now
[](https://i.stack.imgur.com/cwGad.png)
I added this line to the `php.ini` file.
```
allow_url_fopen = On
```
I found the file not on the server under `etc` [this site is hosted on media temple, you might need to contact your own host if you cannot find it]

<pre><code>add_action('wp_head', '//remove title tag command');
</code></pre>
<p>but i didn't find any valid solution so far.</p>

You can see everything added to `wp_head` in the file [`/wp-includes/default-filters.php`](https://github.com/WordPress/WordPress/blob/master/wp-includes/default-filters.php#L237).
If your theme supports the title tag, you can remove it entirely with `remove_action`:
```
remove_action( 'wp_head', '_wp_render_title_tag', 1 );
```
Though it may be simpler/better to use `remove_theme_support( 'title-tag' )` in a child theme, which is what `_wp_render_title_tag` checks before outputting the title tag.

A Custom Walker would be the best way to add anything anywhere to your wp\_nav\_menu
You hav to keep the following in your function.php
```
<?php
class MV_Cleaner_Walker_Nav_Menu extends Walker {
var $tree_type = array( 'post_type', 'taxonomy', 'custom' );
var $db_fields = array( 'parent' => 'menu_item_parent', 'id' => 'db_id' );
function start_lvl(&$output, $depth) {
$indent = str_repeat("\t", $depth);
$output .= "\n$indent<ul class=\"sub-menu\">\n";
}
function end_lvl(&$output, $depth) {
$indent = str_repeat("\t", $depth);
$output .= "$indent</ul>\n";
}
function start_el(&$output, $item, $depth, $args) {
global $wp_query;
$indent = ( $depth ) ? str_repeat( "\t", $depth ) : '';
$class_names = $value = '';
$classes = empty( $item->classes ) ? array() : (array) $item->classes;
$classes = in_array( 'current-menu-item', $classes ) ? array( 'current-menu-item' ) : array();
$class_names = join( ' ', apply_filters( 'nav_menu_css_class', array_filter( $classes ), $item, $args ) );
$class_names = strlen( trim( $class_names ) ) > 0 ? ' class="' . esc_attr( $class_names ) . '"' : '';
$id = apply_filters( 'nav_menu_item_id', '', $item, $args );
$id = strlen( $id ) ? ' id="' . esc_attr( $id ) . '"' : '';
$output .= $indent . '<li' . $id . $value . $class_names .'>';
$attributes = ! empty( $item->attr_title ) ? ' title="' . esc_attr( $item->attr_title ) .'"' : '';
$attributes .= ! empty( $item->target ) ? ' target="' . esc_attr( $item->target ) .'"' : '';
$attributes .= ! empty( $item->xfn ) ? ' rel="' . esc_attr( $item->xfn ) .'"' : '';
$attributes .= ! empty( $item->url ) ? ' href="' . esc_attr( $item->url ) .'"' : '';
$item_output = $args->before;
$item_output .= '<a data-scroll'. $attributes .'>';
$item_output .= $args->link_before . apply_filters( 'the_title', $item->title, $item->ID ) . $args->link_after;
$item_output .= '</a>';
$item_output .= $args->after;
$output .= apply_filters( 'walker_nav_menu_start_el', $item_output, $item, $depth, $args );
}
function end_el(&$output, $item, $depth) {
$output .= "</li>\n";
}
}
?>
```
and then you can call the menu by
```
<?php wp_nav_menu( array( 'menu'=>'Footer Menu 1',
menu_class => 'menu vertical footer-menu',
'walker' => new MV_Cleaner_Walker_Nav_Menu() ) ); ?>
```

<p>I'm developing a plugin and I'd like to use colorbox in my plugin . So I use <code>wp_enqueue_script('jquery');</code> but it doesn't work . Then I search for it and add the following code and it is working now . But why should I deregister jquery ?</p>
<pre><code>wp_deregister_script('jquery');
wp_register_script('jquery', 'http://ajax.googleapis.com/ajax/libs/jquery/1.8.1/jquery.min.js', false, '1.8.1');

I'm developing a plugin and I'd like to use colorbox in my plugin . So I use `wp_enqueue_script('jquery');` but it doesn't work . Then I search for it and add the following code and it is working now . But why should I deregister jquery ?
```
wp_deregister_script('jquery');
wp_register_script('jquery', 'http://ajax.googleapis.com/ajax/libs/jquery/1.8.1/jquery.min.js', false, '1.8.1');
wp_enqueue_script('jquery');
```

Linking jquery code twice conflicts the functions as they are present twice. So deregistering helps you but it is not good choice. You should go through jQuery no conflict thing. And you should register your jquery version with different name, so that it does not break wordpress.
Ref- jQuery [Forum](https://forum.jquery.com/topic/multiple-versions-of-jquery-on-the-same-page) and [Documentation](https://api.jquery.com/jquery.noconflict/)

Actually it is more general question but now i am trying to use it on wordpress site so I preferred to post it here.
I am trying to understand the difference between remote post and form post.
When I query a string and post it to remote server, I get the result as string and with "print $response" see it on browser console. But I want it to be displayed as html on browser. Am I expecting wrong thing or could i do such thing?
Basically I want to see raw response as html.
**EDIT**
In case of being more expressive..
I am trying to write credit card payment gateway inside woocommerce
Inside process\_payment function which is called at the end of customer order, I am posting all info to bank server like below:
```
public function process_payment( $order_id ) {
global $woocommerce;
....
...
$okUrl = "http://localhost/xxx/wc-api/paymentpos/";
$failUrl = "http://localhost/xxx/wc-api/paymentpos/";
$payload = array(.....);
$response = wp_remote_post( $environment_url, array(
'method' => 'POST',
'body' => http_build_query( $payload ),
'timeout' => 45,
'sslverify' => false,
) );
$respbody = wp_remote_retrieve_body($response);
print $respbody;
}
```
After that, bank server should reply to payment\_callback() which is like
```
public function payment_callback(){
global $woocommerce;
wc_add_notice( 'OK', 'success' );
.....
exit();
}
```
I am getting $respbody as below on console.

WordPress uses a [hierarchy of templates](https://developer.wordpress.org/themes/basics/template-hierarchy/) (see the [visual overview](https://developer.wordpress.org/files/2014/10/template-hierarchy.png)) which it checks for presence. In your case when showing a category archive it will check for presence the following files in this order and use the first one it finds:
* category-$slug.php (In your case probably category-news-events.php)
* category-$id.php
* category.php
* archive.php
* [paged.php] if paged
* index.php
So if you want to change things for a specific category, you best create a `category-$slug.php` (copy from `category.php`). If you want to to modify the general presentation of categories modify `category.php` directly. If `category.php` is not present, just use the next existing file according to the hierarchy.

Thanks any advice on this would be great.

I use Multi-Site at `example.com`.
Is there any simple method to redirect users to specific blog dashboard? for example, when I login at:
`example.com/wp-login.php`
instead of default redirection to
`example.com/wp-admin` I want to be redirected to
`example.com/sub-site/wp-admin`
|
please see this it working fine for me :)
```
function uop_login_redirect( $redirect_to, $request, $user ) {
return ( is_array( $user->roles ) && in_array( 'administrator', $user->roles ) ) ? admin_url() : site_url();
}
add_filter( 'login_redirect', 'uop_login_redirect', 10, 3 );
```

We could implement our own endpoint:
```
https://example.tld/wpse/v1/frontpage
```
Here's a simple demo (*PHP 5.4+*):
```
<?php
/**
* Plugin Name: WPSE - Static Frontpage Rest Endpoint
*/
namespace WPSE\RestAPI\Frontpage;
\add_action( 'rest_api_init', function()
{
\register_rest_route( 'wpse/v1', '/frontpage/',
[
'methods' => 'GET',
'callback' => __NAMESPACE__.'\rest_results'
]
);
} );
function rest_results( $request )
{
// Get the ID of the static frontpage. If not set it's 0
$pid = (int) \get_option( 'page_on_front' );
// Get the corresponding post object (let's show our intention explicitly)
$post = ( $pid > 0 ) ? \get_post( $pid ) : null;
// No static frontpage is set
if( ! is_a( $post, '\WP_Post' ) )
return new \WP_Error( 'wpse-error',
\esc_html__( 'No Static Frontpage', 'wpse' ), [ 'status' => 404 ] );
// Response setup
$data = [
'ID' => $post->ID,
'content' => [ 'raw' => $post->post_content ]
];
return new \WP_REST_Response( $data, 200 );
}
```
A successful response is like:
```
{"ID":123,"content":{"raw":"Some content"}}
```
and an error response is like:
```
{"code":"wpse-error","message":"No Static Frontpage","data":{"status":404}}
```
Then we can extend it to support other fields or *rendered* content by applying the `the_content` filter.

To add a option box for a page or post, you need to use `add_meta_boxes` action.
```
//Register Meta Box
function register_meta_box() {
add_meta_box(
'meta-box-id',
__( 'MetaBox Title', 'text-domain' ),
'meta_box_callback',
'post',
'advanced',
'high'
);
}
add_action( 'add_meta_boxes', 'register_meta_box');
//Add field
function meta_box_callback( $post_id ) {
$output = '<label for="title_field">'. esc_html__('Title Field', 'text-domain') .'</label>';
$title_field = get_post_meta( $post_id->ID, 'title_field', true );
$output .= '<input type="text" name="title_field" id="title_field" class="title_field" value="'. esc_attr($title_field) .'" />';
echo $output;
}
// Save meta field
add_action('save_post', 'save_meta_field');
function save_meta_field($post_id){
// Check nonce, sanitize field
update_post_meta($post_id, 'title_field', $_POST['title_field']);
}
```
The `add_meta_box()` parameters must be set to fit your needs (advanced and 'high'), and of course the field name and the screen(s) where your want the box to appears.
You will find more details about `add_meta_boxes` [here](https://developer.wordpress.org/reference/functions/add_meta_box/)
Hope it helps

I'm looking for a function that will count and show .jpg URLs or images in my post and then echo the results (eg. 12 images).
I've only found a way to count the attached images in the post. I also found an xpath function but I'm not sure if it is working, because I can't get it to echo the results.
Here's what I have so far:
```
function post_photo_count_xpath( $post_id ) {
global $wpdb;
$post_id_safe = intval( $post_id );
$html = $wpdb->get_row(
"select * from {$wpdb->posts} where ID={$post_id_safe} limit 1"
);
$doc = new DOMDocument();
@$doc->loadHTML( $html->post_content );
$path = new DOMXpath( $doc );
$images = $path->query( "//img" );
return( $images->length );
}
```
|
Use regex to find all the urls and filter by type.
```
$post = get_post( 504 );
$content = $post->post_content;
// match all urls
preg_match_all( '/(http:|https:)?\/\/([\w_-]+(?:(?:\.[\w_-]+)+))([\w.,@?^=%&:\/~+#-]*[\w@?^=%&\/~+#-])?/', $content, $matches );
$count = 0;
if ( ! empty( $matches ) && ! empty( $matches[ 0 ] ) ) {
foreach ( $matches[ 0 ] as $url ) {
$split = explode( '#', $url );
$split = explode( '?', $split[ 0 ] );
$split = explode( '&', $split[ 0 ] );
$filename = basename( $split[ 0 ] );
$file_type = wp_check_filetype( $filename, wp_get_mime_types() );
if ( ! empty ( $file_type[ 'ext' ] ) ) {
// (optional) limit inclusion based on file type
if( ! in_array( $file_type[ 'ext' ], array('jpg', 'png')) ) continue;
$files[ $url ] = $file_type;
$urls[]=$url;
$count ++;
}
}
}
// print out urls and total count
print_r( array (

Use regex to find all the urls and filter by type.
```
$post = get_post( 504 );
$content = $post->post_content;
// match all urls
preg_match_all( '/(http:|https:)?\/\/([\w_-]+(?:(?:\.[\w_-]+)+))([\w.,@?^=%&:\/~+#-]*[\w@?^=%&\/~+#-])?/', $content, $matches );
$count = 0;
if ( ! empty( $matches ) && ! empty( $matches[ 0 ] ) ) {
foreach ( $matches[ 0 ] as $url ) {
$split = explode( '#', $url );
$split = explode( '?', $split[ 0 ] );
$split = explode( '&', $split[ 0 ] );
$filename = basename( $split[ 0 ] );
$file_type = wp_check_filetype( $filename, wp_get_mime_types() );
if ( ! empty ( $file_type[ 'ext' ] ) ) {
// (optional) limit inclusion based on file type
if( ! in_array( $file_type[ 'ext' ], array('jpg', 'png')) ) continue;
$files[ $url ] = $file_type;
$urls[]=$url;
$count ++;
}
}
}
// print out urls and total count
print_r( array (

I have a "cmb2" custom field with `type->file`. and i use it to upload images.
**If i use:**
`echo get_post_meta( $post->ID, '_pf_photo1', 'medium' );`
i get the url of the full image (not the medium one).
How can i get the url of the 'medium' / 'thumbnail' and so on...
|
The `get_post_meta()` function can help to get the meta field but will not retrieve different size.
Assuming `_pf_photo1` embed the attachment id, you can do something like that:
```
// Note the "_id" suffix
$attachment_id = get_post_meta($post->ID, '_pf_photo1_id', true);
```
Last parameter for this function can not be 'medium',
Now,you can use `$attachment_id` with different function depending on what you really want to get (url, img element...):
```
$attachment_element = wp_get_attachment_image( $attachment_id, 'medium' );
echo $attachment_element;
```
There is more ways to get details for attachment `wp_get_attachment_url()`, `wp_get_attachment_image_src` (that returns an array with url, width, height).
You will find more details to discover these functions [here](https://codex.wordpress.org/Function_Reference/wp_get_attachment_url)
Hope it helps !

In general you can change where items link with [WP Constants](https://codex.wordpress.org/Determining_Plugin_and_Content_Directories#Constants). But according to [`get_admin_url()`](https://core.trac.wordpress.org/browser/tags/4.5.3/src/wp-includes/link-template.php#L3106) it's possible the URL was filtered with `admin_url` in which case you might be able to add a filter with a high priority and override what is being sent. The default is;
```
$url = get_site_url($blog_id, 'wp-admin/', $scheme);
if ( $path && is_string( $path ) )
$url .= ltrim( $path, '/' );
return apply_filters( 'admin_url', $url, $path, $blog_id );
```
As stated before, you should check your installed plugins (mainly security plugins) or `.htaccess` for wild redirects. Try disabling all plugins to narrow down that aspect pretty quick. Be sure to check the `/wp-content/mu-plugins/` folder for auto-loaded plugins.
If you can, search your theme and plugins for any reference to `admin` as well as search your database for `admin` to see where it might be set.

I have a wordpress installation at a location in the form: www.mydomain.com/mysite.
I would like to redirect the DNS such that the address will (always!) appear as mysite.com.
I own both domain names. How can I do the redirection without breaking everything?
|
1) You have to change all references of www.mydomain.com to mysite.com in WP. WP will only respond to the hostname/url that it was configured for. If you make a request with a different url, WP will respond with an error message. WP stores the url in two places wp-config.php and the database. In wp-config.php just do a manual search and replace. For the database one method to change site's url - export the database, do a search and replace, then import (be sure to keep a copy of the original export as backup). There are also plugin that will do the search and replace for you.
2) DNS change. This depends on your DNS provider of www.mydomain.com. Some providers have the ability to add 301 redirects. See if your DNS provider has this capability. If not, you can add 301 redirects into your WP .htaccess near the top
```
RewriteEngine on
RewriteCond %{HTTP_HOST} ^www.mydomain.com [NC]
RewriteRule ^(.*)$ http://example.com/$1 [L,R=301,NC]
```

<p>I recently took over web admin for a nonprofit organization and one of the things they would like changed with their site is to have multiple forms such as contact, volunteer, donations, more info, etc. They would like this data sent in an email so that it can be sent to focus group members but need it sent in a daily/ weekly email rather than an email for each individual submission. I think that an excel file is the best way to accomplish what they want and I have looked at several form plugins but they only support manual export of excel files. Is there either a plugin that supports emailing excel files or is there another way I can automate an export and email that export? Thanks in advance!</p>

<p>I wonder how can I trigger filter hook only when post is saved with new revision directly after user clicked save button or publish new post.</p>
<p>My idea is to replace specific parts of the post, but I don't need to trigger my filter each time ajax request for autosaving is sent or new post draft is created. </p>
<p>I am using this filter right now (don't pay attention to var_dump)</p>
<pre><code> add_filter('wp_insert_post_data', array(&$this, 'filter_post_data'), '99', 2);
function filter_post_data($data, $postarr)
{
var_dump($data);
var_dump($postarr);
exit;
// Change post title
return $data;
}
</code></pre>
<p>And this filter is triggered each time post data is going to be saved into database. But I need to trigger this filter only when user clicks save button.</p>
<p>How can I achieve this ? Should I just check post type, status ... in <code>postarr</code> to determine if this post is going to be saved. How can I be sure that the post is save on user click ? (what argument can tell me this)</p>
<p>Thanks.</p>

My idea is to replace specific parts of the post, but I don't need to trigger my filter each time ajax request for autosaving is sent or new post draft is created.
I am using this filter right now (don't pay attention to var\_dump)
```
add_filter('wp_insert_post_data', array(&$this, 'filter_post_data'), '99', 2);
function filter_post_data($data, $postarr)
{
var_dump($data);
var_dump($postarr);
exit;
// Change post title
return $data;
}
```
And this filter is triggered each time post data is going to be saved into database. But I need to trigger this filter only when user clicks save button.
How can I achieve this ? Should I just check post type, status ... in `postarr` to determine if this post is going to be saved. How can I be sure that the post is save on user click ? (what argument can tell me this)

Look at [`'save_post'`](https://codex.wordpress.org/Plugin_API/Action_Reference/save_post) and
[Post Status Transitions](https://codex.wordpress.org/Post_Status_Transitions).
>
> `save_post` is an action triggered whenever a post or page is created or updated, which could be from an import, post/page edit form, xmlrpc, or post by email. The data for the post is stored in $\_POST, $\_GET or the global $post\_data, depending on how the post was edited. For example, quick edits use $\_POST.

The revision functions can tell you whether this is an autosave:
[`wp_is_post_revision()`](https://codex.wordpress.org/Function_Reference/wp_is_post_revision) / [`wp_get_post_revisions()`](https://codex.wordpress.org/Function_Reference/wp_get_post_revisions).
```
function wpse_save_post( $post_id ) {
// If this is just a revision, so we can ignore it.
if ( wp_is_post_revision( $post_id ) )
return;
$post_title = get_the_title( $post_id );
$post_url = get_permalink( $post_id );
$subject = 'A post has been updated';
$message = "A post has been updated on your website:\n\n";
$message .= $post_title . ": " . $post_url;
}
add_action( 'save_post', 'wpse_save_post' );
```
Here you can update the post content after it was saved using [`wp_update_post()`](https://codex.wordpress.org/Function_Reference/wp_update_post). But be sure to avoid the infinite loop.
```
function my_function( $post_id ){
if ( ! wp_is_post_revision( $post_id ) ){
// unhook this function so it doesn't loop infinitely
remove_action('save_post', 'my_function');
// update the post, which calls save_post again
wp_update_post( $my_args );
// re-hook this function
add_action('save_post', 'my_function');
}
}
add_action('save_post', 'my_function');
```

I want to put a clickable anchor text in this image, Please guide me.
Widget Definition →
```
/*=============Sub Banner ============ */

extract(shortcode_atts(array(
'image' => '',

'link_url' => ''
), $atts));
$variables = '';
$output = '';
if(!empty($image)) :
$variables .= 'padding:'.$padding.';';
$variables .= 'margin:'.$margin.';';
endif;
$output .= '<div class="sub-container '.$class.'" style="'.$variables.'">';
$output .= '<div class="inner-image"><a href="'.$link_url.'" target="_Blank"><img src='.$image.' height="'.$height.'" width="'.$width.'"></a></div>';
$output .= '</div>';
return $output;
}
add_shortcode('subbanner', 'shortcode_subbanner');
```

I think you just need to add link\_url to the shortcode, like so?
[tm\_single\_image animation="fadeInLeft" classname="sub-banner1" image="http://trafficspinners.com/wp-content/uploads/2016/11/wedding-seating-chart-downloadable2.jpg" link\_url="YOUR-LINK-HERE"]
Unless I am not understanding what you mean by 'clickable anchor text'.

I want to have different 404 template for each custom post type.
eg. I have post type name **event** and the link will be
*domain.com/event/my-event-name*
but if it link to page that not have post
*domain.com/event/xxxxxxx*
then it will show 404 page, but I want it different from `404.php` template, I try get post type in `404.php` but it can't because it not have a post to get from.

WordPress 4.7 introduces a new filter that allows us to easily modify the *template hierarchy*:
```
/**
* Filters the list of template filenames that are searched for when retrieving
* a template to use.
*
* The last element in the array should always be the fallback
* template for this query type.
*
* Possible values for `$type` include: 'index', '404', 'archive', 'author', 'category',
* 'tag', 'taxonomy', 'date', 'embed', home', 'frontpage', 'page', 'paged', 'search',
* 'single', 'singular', and 'attachment'.
*
* @since 4.7.0
*
* @param array $templates A list of template candidates, in descending order of priority.
*/
$templates = apply_filters( "{$type}_template_hierarchy", $templates );
```
For the 404 type, we could check the current path, as suggested by @cjbj.
Here's an example where we modify the 404 template hierarchy by supporting the `404-event.php` template, if the current path matches the `^/event/` regex pattern (*PHP 5.4+*):
```
add_filter( '404_template_hierarchy', function( $templates )
{
// Check if current path matches ^/event/
if( ! preg_match( '#^/event/#', add_query_arg( [] ) ) )
return $templates;
// Make sure we have an array
if( ! is_array( $templates ) )
return $templates;
// Add our custom 404 template to the top of the 404 template queue
array_unshift( $templates, '404-event.php' );
return $templates;
} );
```
If our custom `404-event.php` doesn't exists, then `404.php` is the fallback.
We might also just adjust the `404.php` template file to our needs, as suggested by @EliCohen
We could also use the old `404_template` filter (since WordPress 1.5), that's fired after the `locate_template()` is called.
Here's an example (*PHP 5.4+*):
```
add_filter( '404_template', function( $template )
{
// Check if current path matches ^/event/
if( ! preg_match( '#^/event/#', add_query_arg( [] ) ) )
return $template;
// Try to locate our custom 404-event.php template
$new_404_template = locate_template( [ '404-event.php'] );
// Override if it was found
if( $new_404_template )
$template = $new_404_template;
return $template;
} );
```
Hope you can test it further and adjust to your needs!

If you want to retrieve multiple taxonomies you need to put the four taxonomies in an array, you are doing this, but you have put `taxonomy=>` in the array.
```
$terms = get_terms(
'taxonomy' => array(
'vehicle_safely_features',
'vehicle_exterior_features',
'vehicle_interior_features',
'vehicle_extras')

|
In case of `wp_query`, you can't use shortcode this way
```
<?php wp_pagenavi(); ?>
```
You need to use variable (in which you are storing wp\_query) in array inside shortcode. Use shortcode like this instead. Replace above shortcode with below one.
```
<?php wp_pagenavi( array( 'query' => $query_slider ) ); ?>
```
**UPDATE**
This is a way in which I am using `wp_query` to show products list without shortcode that you used to display products.
```
<?php
/*
Template Name: shine
*/
get_header(); ?>
<?php
$paged = get_query_var('paged') ? get_query_var('paged') : 1;
$args = array('post_type' => 'product',
'orderby' => 'title',
'order' => 'ASC',
'posts_per_page' => 5,
'paged' => $paged);
$loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post();
?>
<li style="list-style:none;">
<h3><a href="<?php the_permalink() ?>" title="<?php the_title(); ?>"><?php the_title();?></a> (<?php echo get_the_date('d.m.Y');?>)</h3>
<a href="<?php the_permalink() ?>" title="<?php the_title(); ?>">
<?php
/***** Thumbnail ******/
the_post_thumbnail(
array(120, 90),
array(
'class' => 'enter-class-here', //Specify class for product's image if any
'alt' => 'Preview unavailable', //Specify alternate text for products, in case if there is no products image
'title' => 'Enter-title-here' //Specify title if any
)
);
/******* Thumbnail Ends ********/
?> </a>
</li><hr />
<?php
endwhile; ?>
<?php wp_pagenavi( array( 'query' => $loop ) ); ?>
<?php get_footer();?>

Curl is outputting the response to the screen. You need to send the output to a file, like this:
```
curl https://wordpress.org/latest.tar.gz -o wordpress.tar.gz
```
Note the lowercase 'o', and the presence of a filename after that argument. You can name the file whatever you want. With this exact command, it will be downloaded into whatever folder you are currently in.

<p>I'm running a standard WP_Query on a property website, and I want to find all properties that have a postcode beginning with 'SC1'. In the meta query, doing a normal LIKE on the postcode works, but it also returns properties with postcode SC13, which isn't what I want.</p>
<p>As a result, I've changed my meta query to be as follows:</p>
<pre><code>array(
'key' => '_address_postcode',
'value' => 'SC1 ', // Notice the addition of the space
'compare' => 'LIKE'
)
</code></pre>
<p>However.. it's not working. I've dug deeper and it seems that WordPress is trimming the values:</p>
<p><a href="https://github.com/WordPress/WordPress/blob/af69f4ab1a0b44594b1f231c183f7a533575a893/wp-includes/class-wp-meta-query.php#L597" rel="nofollow noreferrer">https://github.com/WordPress/WordPress/blob/af69f4ab1a0b44594b1f231c183f7a533575a893/wp-includes/class-wp-meta-query.php#L597</a></p>
<p>Any idea how I can search for meta values that specifically have a space at the end? I thought of doing something like so:</p>
<pre><code>array(
'key' => '_address_postcode',
'value' => 'SC1 %',// Add a space then wildcard
'compare' => 'LIKE'

<p>... but that doesn't work. Can anyone think of a way to get around this :-S</p>

Note sure how your structure is, but here's one way, using `RLIKE` comparison and a *space* [character class](https://mariadb.com/kb/en/mariadb/pcre/#character-classes):
```
array(
'key' => '_address_postcode',
'value' => '^SC1[[:space:]]', // Starts with 'SC1 '
'compare' => 'RLIKE'
)
```
Maybe you should consider adjusting the meta values, as suggested by @cybmeta?

<p>I'd like to create a subclass of <code>WP_Post</code> and add some "model functionality" to it. How can i force WP to create objects of that child class instead of WP_Post itself, when i query for my custom post type?</p>
<p><strong>Example:</strong></p>
<p>Let's assume i have two custom post types: <code>Book</code> and <code>Review</code>. Each Book can have many Reviews. On my Book, I want a method to sum up all its reviews. I'd define the following class:</p>
<pre><code>class Book extends WP_Post
{
public function reviewsSummary()
{
// Retrieve all reviews for $this book
// Sum up their ratings
// Return that sum
}
}
</code></pre>
<p>Is there a way, for example when calling <code>register_post_type()</code>, to force WordPress into casting all posts of type "book" into my <code>Book</code> class instead of <code>WP_Post</code>?</p>
<p>Could look something like this:</p>
<pre><code>register_post_type('book', [

`WP_Post` class in WP is `final`, so it explicitly forbids subclassing. It is also quite vague in practice, a lot of code around will happily take/produce post–*like* objects as long as they have established data structure.
It is challenging to recommend an alternative without knowing more about your specific needs. In a general and assuming use in templates the typical would be to create a template tag function that will calculate score for review post, provided to it as argument and/or current in the Loop.

The problem is the `<` and `>` which surround the reset URL in `wp-login.php`. You can remove them using [retrieve\_password\_message](https://developer.wordpress.org/reference/hooks/retrieve_password_message/) in your theme `functions.php` file like below:
```
add_filter("retrieve_password_message", "mapp_custom_password_reset", 99, 4);
function mapp_custom_password_reset($message, $key, $user_login, $user_data ) {
$message = "Someone has requested a password reset for the following account:
" . sprintf(__('%s'), $user_data->user_email) . "
If this was a mistake, just ignore this email and nothing will happen.
To reset your password, visit the following address:
" . network_site_url("wp-login.php?action=rp&key=$key&login=" . rawurlencode($user_login), 'login') . "\r\n";
return $message;
}
```

[WP\_Query](https://codex.wordpress.org/Class_Reference/WP_Query) has [Pagination\_Parameters](https://codex.wordpress.org/Class_Reference/WP_Query#Pagination_Parameters) like `posts_per_page` and `offset` to help you out.

I'm developing a new theme for WP and I want to add different sorts of widgets and different classes, because I want these widgets to look different (for example footer widgets should have another styling, and now I can only target them with the "widget class", one class for all).
```
function create_widget($name, $id, $description) {
register_sidebar(array(
'name' => __( $name ),
'id' => $id,
'description' => __( $description ),
'before_widget' => '<div class="widget">',
'after_widget' => '</div>',
'before_title' => '<h2>',
'after_title' => '</h2>',
));
}
```
Is this even possible or do I have to delete my class "widgets" and adding new classes everytime to the new widget?
|
When registering a sidebar, you can use certain placeholders for the widget classes. Here's an example taken from the codex:
```
'before_widget' => '<li id="%1$s" class="widget %2$s">',
```
It's the lack of `%1$s` and `%2$s` that is causing your issues. When in doubt always read the documentation on the codex and the developer hub/handbooks

<p>I am working on WordPress plugin and I have added support for wp cron there. See the code below:</p>
<pre><code>function __construct(){
//Cron Job
add_action('init', array($this,'g_order_sync'));
add_action('ga_order_syn', array($this,'sync_order'));
add_filter('cron_schedules',array($this,'my_cron_schedules'));
}
function my_cron_schedules($schedules){
if(!isset($schedules["10sec"])){
$schedules["10sec"] = array(
'interval' => 10,
'display' => __('Once every 5 minutes'));
}
return $schedules;
}
public function g_order_sync(){
if( !wp_next_scheduled('ga_order_syn') ) {
wp_schedule_event( time(), '10sec', 'ga_order_syn' );
}
}
public function sync_order(){
$content = "some text here";
$fp = fopen($_SERVER['DOCUMENT_ROOT']. "/myText.txt","wb");
fwrite($fp,$content);
fclose($fp);
}
</code></pre>
<p>When I print cron using <code>print_r( _get_cron_array() );</code>, it shows me that my cron(<code>ga_order_syn</code>) is scheduled every 10 second but <code>sync_order()</code> function does not create file at <code>DOCUMENT_ROOT</code>. If I add a call to the <code>wp_mail()</code> function, it does not send me an mail.</p>
<p>What is issue with my code? Why is it not working?</p>

What is issue with my code? Why is it not working?

This is a fantastic question - I've personally never run into this before, but here's what I'd try, assuming:
* you have an image of a server that you've been using to spin up new instances
* you're using a CDN and cloud storage for images and uploads (rather than having a local uploads folder)
With those two assumptions, it means you can spin up and spin down instances of the server without worrying about data loss - the files and config between each server are identical.
* Spin up a new instance of your server, but don't add it to the load balancer
* point your hosts file to the IP of the instance
* update the plugin on the instance, make sure everything is working as you expect
* create an image of the updated server
* spin up one more instance based on the updated image
* point the LB at the new instances
This is a bit of a painful process, and I think next would also look into automated deployment tools, such as Capistrano, or maybe a service like Deploy.

When you are editing a post you can notice the URL in your browser looks like
```
http://***.com/wp-admin/post.php?post=1351&action=edit
```
The number in the URL corresponds to the ID of your post. So you can access your post with that ID. In this example the short link for the post would be
```
http://***.com/?p=1351
```
When a visitor browsers this URL she will be redirected to the full URL if you have the correct options set in `Settings > Permalinks`.
If you need to get the short URL programatically you can use the [`wp_get_shortlink()`](https://codex.wordpress.org/Function_Reference/wp_get_shortlink) function. This function returns the link, which can then be printed.

If you're going to use redirects and want to display error messages, you have a couple of options.
1. Use the redirect url itself to pass information to the next request.
-----------------------------------------------------------------------
Something like this:
```
wp_safe_redirect('your_plugin_url?msg=' . $message_code);
```
In the view:
```
$messages = array(
'1' => 'Success!',
'2' => 'Something went wrong :('
);
$msg_id = isset($_GET['msg']) ? $_GET['err'] : 0;
if (array_key_exists($msg_id, $messages)) {
echo $messages[$msg_id];
}
```
2. Use the $\_SESSION to pass around data.
------------------------------------------
Put `session_start()` somewhere in the early initialization of your plugin, to make sure it's run before any page output is sent.
Then record the error or success messages in the session:
```
$_SESSION['painting_delete_msg'] = 'success! woot!';
wp_safe_redirect('your_plugin_url');
```
Then in the page:
```
if (isset($_SESSION['painting_delete_msg'])) {
echo $_SESSION['painting_delete_msg'];
unset($_SESSION['painting_delete_msg']);
}
```
The `unset` makes sure that the error is not repeated.
3. Don't use redirects.
-----------------------
```
case "delete":
ob_clean();
ob_start();
$status = Myplugin_Painting_Info::delete($request["painting_id"]);
include_once( "partials/myplugin-admin-paintings.php" );
break;
case "show":
include_once( "partials/myplugin-admin-paintings.php" );
break;
// myplugin-admin-paintings.php
if (isset($status)) {
echo $status->message;
}
```

In my plugin, in `init` action I use `get_sites()` function... however it throws:
`Call to undefined function get_sites() in XYZ on line 154`
whats solution?
p.s.
1) The same happens with `wp_get_sites()`...
2) no help when I use `require_once(ABSPATH . 'wp-includes/ms-blogs.php');`
3) I use wordpress version 4.6
|
Solution seems to be:
```
if(function_exists('get_sites')) {$sites= get_sites();}
elseif(function_exists('wp_get_sites')) {$sites= wp_get_sites();}
```

<p>I'm building a WordPress site for a local newspaper. This newspaper currently has a "service directory" online which is a bunch of yellow-page style ads for different local businesses. Each of these ads is just a single image with a click-through, although there are two different sized ads (priced at different rates) that need to be displayed differently.</p>
<p>The data schema would look something like this (just formatting in JSON for readability -- I know it'll be stored as SQL):</p>
<pre><code>service_link: {
image: 'plumberad01.png'
url: 'http://myplumber.com',
type: 'large',
active: true
}
</code></pre>
<p>I know I can create a new Page and manually add the images and their links, but management becomes a big hassle. What I want to do is create a custom page which just finds all the active service_links, and then formats them properly. I can easily write the PHP necessary to do that.</p>
<p>What I'm not sure of is how to get the service_links added to the database. All my searches just keep coming up with information about custom post types, which doesn't seem to be what I'm looking for as these aren't individual posts. They will only ever be viewed along with everything else.</p>
<p>My guess is I'd need to write a custom plugin (mainly so I can add the service_link management stuff to the menu in wp-admin), so I'm looking for a plugin doing something analogous or some kind of tutorial. I feel like this isn't an uncommon use-case (content that isn't a post), so I don't know why I'm having so much trouble finding information.</p>

From what you describe these ads are separate pieces of information which you want to order and display based on their properties. That would mean storing them as custom posts is still the way to go. After all, posts are the way WordPress stores chunks of related information. That doesn't mean they have to be displayed separately. [Menus are also stored as a post type](https://codex.wordpress.org/Post_Types#Navigation_Menu), even if they are only included in templates that also include regular posts, and are handled in a completely different way.
Now you have the separate ads in a post type, you can use [`wp_query`](https://codex.wordpress.org/Class_Reference/WP_Query) to select them and display them in a template. Roughly, there are two ways to go. If you control the template, you can create widget areas in appropriate places and write a widget that displays the ads. If you don't control the template you can write a shortcode and include it in regular posts/pages.
You would assemble all code (custom post type and widget/shortcode) in a plugin. The benefit of doing it this way would be flexibility for future developments. You could, for instance, place individual ads on content pages, if you would choose to do so.

If the same code works with `add_option()` and not with `$wpdb->insert()` in a custom table, it is probably because the collation of the custom table does not support the characters of the inserted data.
It shoulud work if you set the collation of your table to UTF-8, `utf8_general_ci` at minimum (to allow support for emojis, [WordPress uses `utf8mb4_unicode_ci` since version 4.2](https://make.wordpress.org/core/2015/04/02/the-utf8mb4-upgrade/)).

I wouldn't recommend writing PHP code in the content this way, e.g. for security reasons.
Most likely the shortcode is using `eval()` and you need a valid PHP code snippet in each such call.
The PHP documentation has this [warning](http://php.net/manual/en/function.eval.php):
>
> **Caution** The `eval()` language construct is very dangerous because it
> allows execution of arbitrary PHP code. Its use thus is discouraged.
> If you have carefully verified that there is no other option than to
> use this construct, pay special attention not to pass any user

You should consider writing your own [shortcode](https://codex.wordpress.org/Shortcode_API) instead, keeping the PHP code away from the users and the content editor.

<p>I don't think this is the most elegant way of achieving my objective but it's 95% there.</p>
<p>I have created a page template and added a post loop to list custom posts based on the a custom field set on the page.</p>
<p>I am trying to show a list of associated posts. I have a custom taxonomy 'servicestax' containing values such as 'design' and 'support' I want to show the posts for my custom post type 'Services' with a link to the post.</p>
<p>The issue i face is the permalink is output as the current page url and not a post url from the list of custom posts. I don't really understand why this should be as the thumbnail, title and excerpt all appear as expected.</p>

I don't think this is the most elegant way of achieving my objective but it's 95% there.
I have created a page template and added a post loop to list custom posts based on the a custom field set on the page.
I am trying to show a list of associated posts. I have a custom taxonomy 'servicestax' containing values such as 'design' and 'support' I want to show the posts for my custom post type 'Services' with a link to the post.
The issue i face is the permalink is output as the current page url and not a post url from the list of custom posts. I don't really understand why this should be as the thumbnail, title and excerpt all appear as expected.
The code I have cobbled together is as follows (I have added too much error checking yet!)
```
$key_value = get_field('post_types' );
$custom_terms = get_terms('servicestax');
foreach($custom_terms as $custom_term) {
wp_reset_query();
$args = array('post_type' => 'services',
'tax_query' => array(
array(
'taxonomy' => 'servicestax',
'field' => 'slug',
'terms' => $custom_term->slug,
),
),
);
if (! empty($key_value)){
if ($custom_term->slug == $key_value->slug){
$loop = new WP_Query($args);
if($loop->have_posts()) {
while($loop->have_posts()) : $loop->the_post(); ?>
<div class="listing col-md-8">
<h3><a href="<?php get_post_permalink()?>"><?php the_title()?> </a></h3>
<div class="col-md-3 col-sm-3 hidden-xs"><img class=" hidden-xs" src=" <?php the_post_thumbnail_url( 'thumbnail' )?>"/></div>
<div class="col-md-9 col-sm-9">

<a href="<?php get_post_permalink()?>">more information</a>

Thank you for your help! This solution works with my theme:
```
function remove_all_theme_styles() {
if ( is_page_template('template-landing.php') ) {
global $wp_styles;
$wp_styles->queue = array();
}
}
add_action('wp_print_styles', 'remove_all_theme_styles', 100);

I've read the documentation on [`get_post_permalink()`](https://developer.wordpress.org/reference/functions/get_post_permalink/) and [`get_permalink()`](https://developer.wordpress.org/reference/functions/get_permalink/) and don't understand the difference between the two. It might be because I don't understand the purpose of the `$leavename` and `$sample` parameters. Can anyone explain those, and when one function would be more useful than the other? Thanks!

The [`get_post_permalink()`](https://developer.wordpress.org/reference/functions/get_post_permalink/) funciton fetches the link to a post depending on its "permanent" link plus your custom rewrite rules that changes `?p=123` into for e.g. `my-beautiful-sunday-diary`. The [`get_permalink()`](https://developer.wordpress.org/reference/functions/get_permalink/) function is more "basic" but as well more versatile in what it does: For a `post_type` of
* `page`, it uses `get_page_link()`
* `attachment`, it uses `get_attachment_link()`
* `post`, it uses `get_post_link()`
It also handles the display of `term`s like `category` and date permalinks. At the end, it either replaces the "pretty" link in your `home_url()` or just returns the raw link if no custom rewrite rules were assigned. Finally it attaches a generic filter:
```
/**
* Filters the permalink for a post.
*
* Only applies to posts with post_type of 'post'.
*
* @since 1.5.0
*
* @param string $permalink The post's permalink.
* @param WP_Post $post The post in question.
* @param bool $leavename Whether to keep the post name.
*/
return apply_filters( 'post_link', $permalink, $post, $leavename );
```
Hope that clarifies the topic.
ProTip: If you need to change peramlinks in a plugin, go with the specific filters inside `get_attachment_link()`, `get_post_link()`, etc. Only if you are either working on a single site and are not planning to distribute your code or if you are writing a plugin targetting only rewrite stuff, then go with the generic filter above. Else you will nuke every theme authors efforts and start a callback priority race.

<p>I have a Wordpress site that accepts posts by email and feeds them into specific categories. I just adopted a new theme (Astrid) and while I've been able to customize it with css and child theme, I'm frustrated by the fact that the sidebar is ever present in the category/archive view. Is there a way (perhaps using category.php) to remove the sidebar from all category pages (which for my site would mean all pages except one static "about" page and the homepage itself which shows most recent blog posts).</p>
<p>Thanks much!</p>

category page flow (bottom to top) is like this:
```
category-slug.php
category-ID.php
category.php
archive.php
index.php
```
so you can not create compulsory **category.php**. open your current theme **archive.php**. and edit this code.
```
<?php
if( !is_category() ){
get_sidebar();
}
?>
```

<p>I'm making a plugin to register participations on a contest.
I am using Magic Fields.
On my development server, when I put an entry as a normal user all the data is saved on db and it shows in backend. everytime I try to edti fields as admin, it don't save and send me to "wp-admin/edit.php"</p>
<p>Here's my saving function</p>
<pre><code> add_action('save_post', 'add_fields_contest', 10, 2 );
function add_fields_contest( $id, $post ) {
require_once(ABSPATH . 'wp-includes/pluggable.php');
if ( $post->post_type == 'contest' ) {
update_post_meta( $id, 'userid', $_POST['userid'] );
update_post_meta( $id, 'title', $_POST['title'] );
update_post_meta( $id, 'name', $_POST['name'] );
update_post_meta( $id, 'age', $_POST['age'] );
}
}
</code></pre>
<p>All fields exist, I have a metabox created and I really don't know why this isn't saving.</p>

I'm making a plugin to register participations on a contest.
I am using Magic Fields.
On my development server, when I put an entry as a normal user all the data is saved on db and it shows in backend. everytime I try to edti fields as admin, it don't save and send me to "wp-admin/edit.php"
Here's my saving function
```
add_action('save_post', 'add_fields_contest', 10, 2 );
function add_fields_contest( $id, $post ) {
require_once(ABSPATH . 'wp-includes/pluggable.php');
if ( $post->post_type == 'contest' ) {
update_post_meta( $id, 'userid', $_POST['userid'] );
update_post_meta( $id, 'title', $_POST['title'] );
update_post_meta( $id, 'name', $_POST['name'] );
update_post_meta( $id, 'age', $_POST['age'] );
}
}
```
All fields exist, I have a metabox created and I really don't know why this isn't saving.
|
category page flow (bottom to top) is like this:
```
category-slug.php
category-ID.php
category.php
archive.php
index.php
```
so you can not create compulsory **category.php**. open your current theme **archive.php**. and edit this code.
```
<?php
if( !is_category() ){
get_sidebar();
}
?>
```

<p>I have a website which the post's contents are dynamically generated AFTER a post is published. </p>
<p>I'm using this code to generate the content i want:</p>
<p><code>add_action( 'publish_post', 'generate_content');
function generate_content($post){
//some code here
}</code></p>
<p>This process can sometimes take up to 5 minutes, while the post is instantly published (I already set the php timeout to 600 seconds).</p>
<p>I want to schedule the post for when the function has finished it's task, or to save the post as draft and automatically publish it when it's ready.</p>
<p>Is there a way to achieve this? Any help is appreciated.</p>

I have a website which the post's contents are dynamically generated AFTER a post is published.
I'm using this code to generate the content i want:
`add_action( 'publish_post', 'generate_content');
function generate_content($post){
//some code here
}`
This process can sometimes take up to 5 minutes, while the post is instantly published (I already set the php timeout to 600 seconds).
I want to schedule the post for when the function has finished it's task, or to save the post as draft and automatically publish it when it's ready.
Is there a way to achieve this? Any help is appreciated.

There might be two ways:
```
add_action( 'draft_post', 'wpse_246730_my_function' );
function wpse_246730_my_function( $post_id, $post )
{
// Do your things
// Just to stay safe
remove_action( 'draft_post', 'wpse_246730_my_function' );
wp_publish_post( $post_id );
add_action( 'draft_post', 'wpse_246730_my_function' );
}
```
Or make the post future status, and set a time after 10 or 20 mins to publish. Then use the following code:
```
add_action( 'future_post', 'wpse_246730_my_function' );
function wpse_246730_my_function( $post_id, $post )
{
// Do your things
}
```

<p>I am using <a href="https://github.com/sbrajesh/multisite-global-terms/blob/master/mu-global-terms.php" rel="nofollow noreferrer">this function</a> to make categories and tags global on my multisite installation.</p>
<p>An unfortunate side effect of global categories/tags is that it displays categories for posts across all sites. This creates two undesirable problems:</p>
<ol>
<li>It shows categories/tags that the current blog has no posts for, linking to an archive with a 'not found' message.</li>
<li>For count, WordPress looks at all of the blogs in the network, finds the highest total for each category/tag from all blogs within the network and displays that number.</li>
</ol>
<p>When I display categories or tags in a dropdown on an individual site, I only want categories from the current blog_id to show in the list with the count from the number of corresponding posts in the current blog.</p>
<p>I have tried to limit the posts in a category dropdown with meta_query, but it's not working for me:</p>
<pre><code><form id="category-select" class="category-select" action="<?php echo esc_url( home_url( '/' ) ); ?>" method="get">
$blog_id = get_current_blog_id();
$args = array(
'show_option_none' => __( 'Select Category' ),
'show_count' => 1,
'orderby' => 'name',
'echo' => 0,
'meta_query' => array(
'key' => 'blog_id',
'value' => $blog_id,

);
$select = wp_dropdown_categories( $args );
$replace = "<select$1 onchange='return this.form.submit()'>";
$select = preg_replace( '#<select([^>]*)>#', $replace, $select );
<noscript>
<input type="submit" value="View" />
</noscript>
</form>
</code></pre>
<p>Any way to modify this meta_query parameter or tackle this from another angle?</p>

I am using [this function](https://github.com/sbrajesh/multisite-global-terms/blob/master/mu-global-terms.php) to make categories and tags global on my multisite installation.
An unfortunate side effect of global categories/tags is that it displays categories for posts across all sites. This creates two undesirable problems:
1. It shows categories/tags that the current blog has no posts for, linking to an archive with a 'not found' message.
2. For count, WordPress looks at all of the blogs in the network, finds the highest total for each category/tag from all blogs within the network and displays that number.
When I display categories or tags in a dropdown on an individual site, I only want categories from the current blog\_id to show in the list with the count from the number of corresponding posts in the current blog.
I have tried to limit the posts in a category dropdown with meta\_query, but it's not working for me:

$args = array(

<p>I have a code which shows categories list with images. Im using plugin to attach image to category.</p>
<p>Working code is:</p>
<pre><code><?php
$args=array(

)
?>
<?php foreach (get_categories( $args ) as $cat) : ?>

<a href="<?php echo get_category_link($cat->term_id); ?>"><img src="<?php echo z_taxonomy_image_url($cat->term_id); ?>" /></a>
<?php endforeach; ?>
</code></pre>
<p>Problem is theres a lot of categories. I want to separate them by year (just add a line or text or something). Is it even possible? I know that categories dont store date. Posts are posted only in categories of current year so maybe this could help?</p>

```

What do you have in loop-gallery.php? That's the file which will show the content of the gallery post.
If you haven't created a loop-gallery.php, you should create a file with that name and put it in the root theme folder. In that file you could put something like the following to show the content:
```
<div>
<h2><?php the_title(); ?></h2>
<div><?php the_content(); ?></div>
</div>
```
You could obviously put something more complex in that file, if you however don't need more than that and you're not reusing the snippet elsewhere in your theme you could simply do the following change to your code to get the same result:
```
while ( have_posts() ) : the_post();
<div>
<h2><?php the_title(); ?></h2>
<div><?php the_content(); ?></div>
</div>
<?php endwhile; ?>
```
Also, have you recently registered your custom post type? If so you may have to reset your permalinks (although that shouldn't have anything to do with this specfic use case. To reset your permalinks, simply visit Settings > Permalinks and hit save. That will resave the permalinks on your site, including the new permalinks for the custom post type.

I want to show font awesome icon (installed) on the left side of the WordPress widget title. I found this shortcode that should do the work.
```
add_filter( 'widget_title', 'do_shortcode' );
add_shortcode( 'icon', 'shortcode_fa' );
function shortcode_fa($attr, $content ) {
return '<i class="fa fa-'. $content . '"></i>';
}
```
After adding this in `functions.php`, I should be able to add a gear icon in the widget title with below code from **Appearence>Widget**
```
[icon]cog[icon]
```
But it is not working.
|
I checked your code in my install. It works, except that you made a typo (missing backslash):
```
[icon]cog[/icon]
```
Few notes:
* You must make sure to **enqueue** the *Font Awsesome* stylesheet.
* You must **close the shortcode**, like: `[icon]cog[/icon]`
* Remember to **escape** the class name with `esc_attr()`.
* Another shortcode idea: `[fa icon="cog"]`

<p>Given an array of Post objects, how might one initialize <a href="https://codex.wordpress.org/The_Loop" rel="nofollow noreferrer">The Loop</a> so that the common Loop functions could be used:</p>
<pre><code>$posts = array( /* WP_Post, WP_Post, ... */);
while ( have_posts() ) {
the_post();
the_title();
}
</code></pre>
<p>I am aware that I could simply loop over the array elements and pass to each function the ID of each element, however for reasons beyond my control using the actual Wordpress Loop is preferred here.</p>
<p>The array is provided from a function that I cannot alter. For purposes of discussion it might as well have come from <a href="http://php.net/manual/en/function.unserialize.php" rel="nofollow noreferrer">unserialize()</a>.</p>

<p>I am trying to list the name of the moderators (users with editor role) that publish pending posts. I created a dashboard widget that shows the latest 10 published posts and the author, but I have problems getting the user that published it.

Here's my code so far:</p>
<pre><code>function dashboard_widget_function() {

$recent_posts = wp_get_recent_posts( $args );

foreach( $recent_posts as $recent ){
$post_author = get_user_by( 'id', $recent['post_author'] );

The reason that `get_the_modified_author()` is not working is that it relies on being used within the WordPress loop. `wp_get_recent_posts()` does not set up a global post object. Here is a complete example based on your original code that replaces `get_the_modified_author()` with some simple code to get the name of the last person who edited the post (which is essentially what `get_the_modified_author()` does):
```
/**

*/
function example_add_dashboard_widgets() {
wp_add_dashboard_widget(
'example_dashboard_widget', // Widget slug.
'Example Dashboard Widget', // Title.
'example_dashboard_widget_function' // Display function.
);
}
add_action( 'wp_dashboard_setup', 'example_add_dashboard_widgets' );
function example_dashboard_widget_function() {
$items_to_show = 10;
$counter = 0;
$recent_posts = wp_get_recent_posts( [
'post_status' => 'publish',
'numberposts' => '50', // More than we want, but tries to ensure we have enough items to display.
'post_type' => 'post'
] );
echo '<table>
<tr>
<th>Post Title</th>
<th>Author</th>
<th>Moderated by</th>
</tr>';
foreach ( $recent_posts as $recent ) {
$post_author = get_user_by( 'id', $recent['post_author'] );
$last_user_id = get_post_meta( $recent['ID'], '_edit_last', true );
$last_user = get_userdata( $last_user_id );
// Bail out of the loop if we've shown enough items.
if ( $counter >= $items_to_show ) {
break;
}
// Skip display of items where the author is the same as the moderator:
if ( $post_author->display_name === $last_user->display_name ) {
continue;
}
echo '<tr><td><a href="' . get_permalink( $recent['ID'] ) . '" title="Read: ' .
esc_attr( $recent['post_title'] ).'" >' . $recent['post_title'].'</a></td>';
echo '<td>'. esc_html( $post_author->display_name ) .'</td>';

$counter++;
}
echo '</table>';
}
```

<p>So I have a main domain site called: site.com and I recently bought wildcard SSL to try and get the main domain and all its sub-domains to be encrypted and be force all files to use https. After signing up for the service the certificate covers all domains like: *.site.com but all my subdomains have their own name like site2.com site3.com siteN.com etc. I can get https if i use site2.site.com but I need it to be site2.com with https. I've installed HTTPS plugin and if I put site2.site.com as the certificate root it works but the URL is then site2.site.com. Is there a way I can force https through site2.com?

<p>I'm using <code>get_posts()</code> to fetch posts from a particular category to display at the top of my homepage, separate from the main homepage Loop. Everything seems to work fine, but for the title (returned through <code>the_title()</code>) which is always the same; the title of the first post fetched by <code>get_posts()</code>. <code>the_permalink()</code> does the same as well, but <code>the_excerpt()</code> returns the correct result for each post.</p>

I'm using `get_posts()` to fetch posts from a particular category to display at the top of my homepage, separate from the main homepage Loop. Everything seems to work fine, but for the title (returned through `the_title()`) which is always the same; the title of the first post fetched by `get_posts()`. `the_permalink()` does the same as well, but `the_excerpt()` returns the correct result for each post.
Here's my code (I have removed only a few lines for fear I might inadvertently remove what is causing this problem):
```
$query = get_posts(array(
'numberposts'=>-1,
'category'=>3
));
$events = array();
if ($query) {
foreach ($query as $tpost) {
$fields = get_post_custom($tpost->ID);
if (isset($fields['event_start'])) {
$usetime = $fields['event_start'][0];
if (isset($fields['event_end'])) {
$usetime = $fields['event_end'][0];
}
if ($usetime>time()) {
$events[] = array("post"=>$tpost,"fields"=>$fields);
}
}
}
usort($events,function($a,$b){
$a = $a['fields']['event_start'][0];
$b = $b['fields']['event_start'][0];
if ($a==$b) { return 0; }
return ($a < $b) ? -1 : 1;
});
}
if (count($events)>0) { ?>
<div class="pad10 tac">
<h2 class="mar10">Upcoming Events</h2>

<?php foreach ($events as $event ) { ?>
<?php setup_postdata( $event['post'] );?>

Making Milos's comment into an answer....
The problem you are facing is the result of many wordpress template oriented functions expect some global variables. In `WP_Query` based loops setting those variable is done by calling the `the_post()` method of the `WP_Query` object, but with `get_posts` you need to call `setup_postdata()` for that.
My personal preference is to just try to avoid functions like `the_title` in favor of functions like `get_the_title`, that accept an explicit post id, whenever possible.

The problem here is that if the site is actually using something like Redis, or any other supported "external cache" then nothing is going to actually be set in the options table (which can be checked with `wp_using_ext_object_cache`)
Storage in the options table is just how WordPress handles transients outside of any external caching (or local object caching).
With that said, to calculate the time remaining, you would do something like this:
```
$expires = (int) get_option( '_transient_timeout_MY_TRANSIENT_NAME', 0 );
$time_left = $expires - time();
```
The value for expiration is calculated by adding `time()` to the value passed when setting the transient, so to get time left, just subtract `time()` from the value set for expiration

I found this question very interesting ,So here is what i have done to make this possible.
Fetch page template and add them as sub menu of Post type page.
```
function addTemplateAddNewSubMenu() {
global $submenu;
// here we are fetching all page template from current activated theme.
$templates = wp_get_theme()->get_page_templates( 'page' );
foreach ( $templates as $filename => $title ) {
if ( $filename != 'default' && $filename != '' ) {
// add page-template filename as query string to add new page link.
$url = 'post-new.php?post_type=page&template=' . $filename;
$submenu['edit.php?post_type=page'][] = array( 'Add new ' . $title , 'manage_options', $url );
}
}
}
add_action( 'admin_menu', 'addTemplateAddNewSubMenu' );
```
I have added page template as query string to
```
/wp-admin/post-new.php?post_type=page&template=template-contact.php
```
Making page template dropdown selected by jQuery and template Query string.
```
add_action( 'admin_head','selectPageTemplate' );
function selectPageTemplate() {
global $pagenow;
if ( $pagenow == 'post-new.php' ) {
if ( get_post_type() == 'page' && isset($_GET['template']) ) {
$template = $_GET['template']; ?>
<script>
jQuery(function($){
$('#page_template').val('<?php echo $template;?>');
});
</script>
<?php
}
}
}
```

is your file name is 'include-nav.php' or it is placed inside 'include' folder ?
if not then simply call it by passing name of **nav.php**
```
<?php get_template_part( 'nav' ); ?>
```
you don't have to pass include keyword to call template.
Hope this help :)

Performance impact of hooked functionality is determined by how often hook fires and how intensive the operation is.
`init` only ever fires one per load, so multiple runs are not a factor for it.
Mostly the thing you need to pay attention to is context. If your logic fires on every load and result is conditional the first thing it should do is determine if the context is the one you want. In all other cases that it the *only* thing it should do.
As long as your context check is lightweight the performance impact should be perfectly insignificant.
If your context check *is* heavy for some reason you might want to find a more specific hook (such as those in template loader logic) that would fire less and in more narrow circumstances. But for something as simple as example you made that won't be necessary.

<p>I have created a custom login page that uses wp_login_form() to create the login form:</p>
<pre><code><div class="login-form">
<?php
wp_login_form( array(
'remember' => false,
'label_username' => '',
'label_password' => ''
)
);
?>
</div>
</code></pre>
<p>I tried to add a simple message to the login form using the default example from the WordPress Codex page about the <a href="https://codex.wordpress.org/Plugin_API/Action_Reference/login_form" rel="nofollow noreferrer">login form action hook</a>, like this:</p>
<pre><code>add_action( 'login_form', function(){
//Adding the text
?>
<p>You can type a little note to those logging in here.</p>
<?php
});
</code></pre>
<p>I literally copy-pasted the last code snippet from the Codex into my custom themes <em>functions.php</em>, to test if it's working.</p>
<p>Now, when I open my custom login page, the text does not appear, but when I open the default login page, the text does appear.</p>
<p>So, does wp_login_form() simply not use the login_form action hook or am I missing something?</p>

I have created a custom login page that uses wp\_login\_form() to create the login form:
```
<div class="login-form">
<?php
wp_login_form( array(
'remember' => false,
'label_username' => '',
'label_password' => ''
)
);
?>
</div>
```
I tried to add a simple message to the login form using the default example from the WordPress Codex page about the [login form action hook](https://codex.wordpress.org/Plugin_API/Action_Reference/login_form), like this:
```
add_action( 'login_form', function(){
//Adding the text
?>
<p>You can type a little note to those logging in here.</p>
<?php
});
```
I literally copy-pasted the last code snippet from the Codex into my custom themes *functions.php*, to test if it's working.
Now, when I open my custom login page, the text does not appear, but when I open the default login page, the text does appear.
So, does wp\_login\_form() simply not use the login\_form action hook or am I missing something?

Performance impact of hooked functionality is determined by how often hook fires and how intensive the operation is.
`init` only ever fires one per load, so multiple runs are not a factor for it.
Mostly the thing you need to pay attention to is context. If your logic fires on every load and result is conditional the first thing it should do is determine if the context is the one you want. In all other cases that it the *only* thing it should do.
As long as your context check is lightweight the performance impact should be perfectly insignificant.
If your context check *is* heavy for some reason you might want to find a more specific hook (such as those in template loader logic) that would fire less and in more narrow circumstances. But for something as simple as example you made that won't be necessary.

A post's title (`post_title`) is not saved in meta data; it's a field within the post table.
Here's an updated version of your original code.
* [Infinite loop is
prevented](https://codex.wordpress.org/Function_Reference/wp_update_post)
by removing and then readding the `wpse246957_update_post_info`
callback.
* Post title is successfully saved with the suffix `- $post_id` [A
check is in place](https://stackoverflow.com/a/1018803/3059883) to
prevent the suffix from being re-added if it has already been added.
```
add_action( 'save_post', 'wpse246957_update_post_info', 10, 3 );
function wpse246957_update_post_info( $post_id, $post, $update ) {
// Stop anything from happening if revision
if ( wp_is_post_revision( $post_id ) ) {
return;
}
// unhook this function so it doesn't loop infinitely
remove_action( 'save_post', 'wpse246957_update_post_info' );
// get post type
$post_type = get_post_type( $post_id );
// If this isn't a custom post, don't update it.
// if ( "cbre_access_form" != $post_type ) return;
// run codes based on post status
$post_status = get_post_status();
if ( $post_status != 'draft' ) {
if ( isset( $_POST['post_title'] ) ) {
$suffix = ' - ' . $post_id;
if ( ! preg_match( '/' . preg_quote( $suffix, '/' ) . '$/', $_POST['post_title'] ) ) {
wp_update_post( [
"ID" => $post_id,
"post_title" => $_POST['post_title'] . $suffix,
] );
}
}
}
// re-hook this function
add_action( 'save_post', 'wpse246957_update_post_info', 10, 3 );
}
```
Personally, I'd probably append the suffix before outputting the title in your template file or wherever you are outputting the title because there could be some edge case with the approach above when it comes to re-saving the post title.

`Walker_Nav_Menu` isn't what you would use for this.
Instead, use the `wp_get_nav_menu_items` filter. Before we start, you need some way of allowing the code to identify which is the menu item/page that you wish to be the parent of the list of posts. You can do this with a CSS class - give the parent menu item a CSS class in admin panel, let's call it 'doctors-parent-item'.
```
add_filter( 'wp_get_nav_menu_items', 'my_theme_doctors_menu_filter', 10, 3 );
function my_theme_doctors_menu_filter( $items, $menu, $args ) {
$child_items = array(); // here, we will add all items for the single posts
$menu_order = count($items); // this is required, to make sure it doesn't push out other menu items
$parent_item_id = 0; // we will use this variable to identify the parent menu item
//First, we loop through all menu items to find the one we want to be the parent of the sub-menu with all the posts.
foreach ( $items as $item ) {
if ( in_array('doctors-parent-item', $item->classes) ){
$parent_item_id = $item->ID;
}
}
if($parent_item_id > 0){
foreach ( get_posts( 'post_type=rt_doctors&numberposts=-1' ) as $post ) {
$post->menu_item_parent = $parent_item_id;
$post->post_type = 'nav_menu_item';
$post->object = 'custom';
$post->type = 'custom';
$post->menu_order = ++$menu_order;
$post->title = $post->post_title;
$post->url = get_permalink( $post->ID );
array_push($child_items, $post);
}
}
return array_merge( $items, $child_items );
}
```
Your menu will now dispaly all `rt_doctors`'s in a sub menu underneath the menu item that you gave the CSS class 'doctors-parent-item`

<p>I want a <code><div></code> from a specific site in <code>xxxx.com/en</code> to appear on the other sites. Let's say I have <code><div id="table1">xxxx<div></code> on <code>xxxx.com/en/page1</code>; I want this to show on <code>xxxx.com/de/page1</code>.</p>
<p>I did not think this would be so complicated in WordPress. With plain PHP, it would be just an include, but WordPress is a closed system. So, how can I do this? </p>

I want a `<div>` from a specific site in `xxxx.com/en` to appear on the other sites. Let's say I have `<div id="table1">xxxx<div>` on `xxxx.com/en/page1`; I want this to show on `xxxx.com/de/page1`.
I did not think this would be so complicated in WordPress. With plain PHP, it would be just an include, but WordPress is a closed system. So, how can I do this?

`Walker_Nav_Menu` isn't what you would use for this.
Instead, use the `wp_get_nav_menu_items` filter. Before we start, you need some way of allowing the code to identify which is the menu item/page that you wish to be the parent of the list of posts. You can do this with a CSS class - give the parent menu item a CSS class in admin panel, let's call it 'doctors-parent-item'.
```
add_filter( 'wp_get_nav_menu_items', 'my_theme_doctors_menu_filter', 10, 3 );
function my_theme_doctors_menu_filter( $items, $menu, $args ) {
$child_items = array(); // here, we will add all items for the single posts
$menu_order = count($items); // this is required, to make sure it doesn't push out other menu items
$parent_item_id = 0; // we will use this variable to identify the parent menu item
//First, we loop through all menu items to find the one we want to be the parent of the sub-menu with all the posts.
foreach ( $items as $item ) {
if ( in_array('doctors-parent-item', $item->classes) ){
$parent_item_id = $item->ID;
}
}
if($parent_item_id > 0){
foreach ( get_posts( 'post_type=rt_doctors&numberposts=-1' ) as $post ) {
$post->menu_item_parent = $parent_item_id;
$post->post_type = 'nav_menu_item';
$post->object = 'custom';
$post->type = 'custom';
$post->menu_order = ++$menu_order;
$post->title = $post->post_title;
$post->url = get_permalink( $post->ID );
array_push($child_items, $post);
}
}
return array_merge( $items, $child_items );
}
```
Your menu will now dispaly all `rt_doctors`'s in a sub menu underneath the menu item that you gave the CSS class 'doctors-parent-item`

<p>I have a custom taxonomy called prod-cat</p>
<p>I want to order the output in the template by number, so I added a term_meta to the taxonomy like this:</p>
<pre><code>add_action( 'prod-cat_add_form_fields', 'add_feature_group_field', 10, 2 );
function add_feature_group_field($taxonomy) {
?>
<div class="form-field term-order-wrap">
<label for="term-order">Order</label>
<input type="text" name="wm-cat-prod-order" />
</div>
<?php
}
</code></pre>
<p>And then:</p>
<pre><code>add_action( 'created_prod-cat', 'save_feature_meta', 10, 2 );
function save_feature_meta( $term_id, $tt_id ){
if( isset( $_POST['wm-cat-prod-order'] ) && '' !== $_POST['wm-cat-prod-order'] ){
add_term_meta( $term_id, 'wm-cat-prod-order', $_POST['wm-cat-prod-order'], true );
}
}
</code></pre>
<p>I have the term_meta working, It's getting saved. Then in the template I do this: </p>
<pre><code>$args = array(
'taxonomy' => 'categoria-de-productos',
'orderby' => 'wm-cat-prod-order',
'order' => 'ASC',
'hide_empty' => false,
'hierarchical' => false,
'parent' => 0,
);
$terms = get_terms( $args );
</code></pre>
<p>But I can't get it to orderby the "wm-cat-prod-order" meta.
Anyone on this?
Thanks</p>

I have a custom taxonomy called prod-cat
I want to order the output in the template by number, so I added a term\_meta to the taxonomy like this:
```
add_action( 'prod-cat_add_form_fields', 'add_feature_group_field', 10, 2 );
function add_feature_group_field($taxonomy) {

<div class="form-field term-order-wrap">

`get_terms` supports a `meta_query` which calls a new [WP\_Meta\_Query](https://codex.wordpress.org/Class_Reference/WP_Meta_Query) parameter as you can see [here](https://developer.wordpress.org/reference/functions/get_terms/). To query your terms with your desired meta, you could change your function call to something like this:
```php
$args = array(
'taxonomy' => 'categoria-de-productos',
'orderby' => 'meta_value_num',
'order' => 'ASC',
'hide_empty' => false,
'hierarchical' => false,
'parent' => 0,
'meta_query' => [[
'key' => 'wm-cat-prod-order',
'type' => 'NUMERIC',
]],
);
$terms = get_terms( $args );
```
This code is untested and may needs to be changed in your example. But the links should guide you to the solution.

<p>Been looking around on this website and the internet but can't seem to find a solution. My client wants every order which has the order status cancelled to be completely removed out of WooCommerce after an amount of time.</p>
<pre><code><?php
function update_order_status( $order_id ) {
$order = new WC_Order( $order_id );
$order_status = $order->get_status();
if ('cancelled' == $order_status || 'failed' == $order_status || 'pending' == $order_status ) {
wp_delete_post($order_id,true);
}
}
</code></pre>
<p>I currently have the above code snippet but I want this action to be delayed 5 minutes because pending orders could be still in payment.</p>
<p>So TL;DR
Orders with status 'cancelled', 'failed' & 'pending' should be completely deleted after 5 minutes.</p>
<p>Anyone who could help me out on this one?</p>
<p>Best regards,

<p>I need to show in the each post his parent category and sub category, at the moment I use this code:</p>
<pre><code><?php
$categories = get_the_category();
echo 'Parent Category: <a href="' . esc_url( get_category_link( $categories[0]->term_id ) ) . '">' . esc_html( $categories[0]->name ) . '</a> \n';
echo 'Sub Category: <a href="' . esc_url( get_category_link( $categories[1]->term_id ) ) . '">' . esc_html( $categories[1]->name ) . '</a>';
?>
</code></pre>
<p>The problem is that this code gives categories[0] and categories[1] values based on their order. In some post the order is Parent -> Sub, in others is Sub -> Parent (don't know why). So when I access $categories[1] in some posts I get the parent instead of the sub.</p>

$categories = get_the_category();
echo 'Parent Category: <a href="' . esc_url( get_category_link( $categories[0]->term_id ) ) . '">' . esc_html( $categories[0]->name ) . '</a> \n';
echo 'Sub Category: <a href="' . esc_url( get_category_link( $categories[1]->term_id ) ) . '">' . esc_html( $categories[1]->name ) . '</a>';
?>
```
The problem is that this code gives categories[0] and categories[1] values based on their order. In some post the order is Parent -> Sub, in others is Sub -> Parent (don't know why). So when I access $categories[1] in some posts I get the parent instead of the sub.
|
do the following code in your child theme function.php file as given below.
```
function wc_remove_cancelled_status( $statuses ){
if( isset( $statuses['wc-cancelled'] ) ){
unset( $statuses['wc-cancelled'] );
}
return $statuses;
}
add_filter( 'wc_order_statuses', 'wc_remove_cancelled_status' );
```

<p>I've generated three different custom post types (e.g. books, movies, games). I've also created a custom taxonomy for all of them (e.g. genre).</p>
<p>What I need are archives for the taxonomy based on the post types. For example: "books-genre", "movies-genre"...</p>
<p>Is there any solution to do that? Now I've only the taxonomy archive for "genre".</p>

I've generated three different custom post types (e.g. books, movies, games). I've also created a custom taxonomy for all of them (e.g. genre).
What I need are archives for the taxonomy based on the post types. For example: "books-genre", "movies-genre"...
Is there any solution to do that? Now I've only the taxonomy archive for "genre".
|
Here is a complete example made possible using [`add_rewrite_rule()`](https://codex.wordpress.org/Rewrite_API/add_rewrite_rule). The basic setup for this example is documented first, then we'll get to the real part of the solution using `add_rewrite_rule()`.
Taxonomy and Post Type registration
-----------------------------------
Register the `genre` taxonomy and the `book`, `movie`, and `game` post types *(note that the singular version of each of these names is being used in this example because it's considered a [best practice](https://softwareengineering.stackexchange.com/questions/103720/classes-naming-singular-or-plural))*.
```
// Create taxonomy: genre for post types: book, movie, and game
// https://codex.wordpress.org/Function_Reference/register_taxonomy
add_action( 'init', 'wpse247013_register_taxonomies', 0 );
function wpse247013_register_taxonomies() {
$args = [
'public' => true,
'hierarchical' => false,
'label' => __( 'Genres', 'textdomain' ),
'show_ui' => true,
'show_admin_column' => true,
'query_var' => 'genre',
'rewrite' => [ 'slug' => 'genres' ],
];
register_taxonomy( 'genre', [ 'book', 'movie', 'game' ], $args );
}
// Create post types: movie, book, and game
// https://developer.wordpress.org/reference/functions/register_post_type/
add_action( 'init', 'wpse247013_register_post_types' );
function wpse247013_register_post_types() {
$book_args = [
'label' => __( 'Books', 'textdomain' ),
'public' => true,
'publicly_queryable' => true,
'show_ui' => true,
'show_in_menu' => true,
'query_var' => true,
'rewrite' => [ 'slug' => 'books' ],
'capability_type' => 'post',
'has_archive' => true,
'hierarchical' => false,
'menu_position' => null,
'supports' => [ 'title', 'editor', 'author', 'thumbnail', 'excerpt', 'comments' ],
'taxonomies' => [ 'genre' ],
];
register_post_type( 'book', $book_args );
$movie_args = [
'label' => __( 'Movies', 'textdomain' ),
'public' => true,
'publicly_queryable' => true,
'show_ui' => true,
'show_in_menu' => true,
'query_var' => true,
'rewrite' => [ 'slug' => 'movies' ],
'capability_type' => 'post',
'has_archive' => true,
'hierarchical' => false,
'menu_position' => null,
'supports' => [ 'title', 'editor', 'author', 'thumbnail', 'excerpt', 'comments' ],
'taxonomies' => [ 'genre' ],
];
register_post_type( 'movie', $movie_args );
$game_args = [
'label' => __( 'Games', 'textdomain' ),
'public' => true,
'publicly_queryable' => true,
'show_ui' => true,
'show_in_menu' => true,
'query_var' => true,
'rewrite' => [ 'slug' => 'games' ],
'capability_type' => 'post',
'has_archive' => true,
'hierarchical' => false,
'menu_position' => null,
'supports' => [ 'title', 'editor', 'author', 'thumbnail', 'excerpt', 'comments' ],
'taxonomies' => [ 'genre' ],
];
register_post_type( 'game', $game_args );
}
```
Basic URL Examples
------------------
>
> Based on the setup above, we'll get these URLs out of the box:
>
>
> **Post type archive URLs**
>
>
> * <http://example.com/books/>
> * <http://example.com/movies/>
> * <http://example.com/games/>
>
>
> **Single post type URLs**
>
>
> * <http://example.com/books/>{book-post-slug}
> * <http://example.com/movies/>{movie-post-slug}
> * <http://example.com/games/>{game-post-slug}
>
>
> **Taxonomy Term archive URLs**
>
>
> * <http://example.com/genres/>{genre-term-slug}
>
> *(this archive will include **all** post types, which is not what we're after)*
>
>
>
Handle rewrite rules
--------------------
Rewrite rules must be added in order to limit a particular genre term to a single post type. An additional rule is needed for pagination for each post type.
```
/**
* Add rewrite rules for genre terms limited to book, movie, and game post types.
* Pagination issue fix via http://wordpress.stackexchange.com/a/23155/2807
* @link https://codex.wordpress.org/Rewrite_API/add_rewrite_rule
*/
function wpse247013_rewrite_rules() {
// Book Genres
add_rewrite_rule( '^books/book-genres/([^/]+)/?$',
'index.php?taxonomy=genre&post_type=book&term=$matches[1]', 'top' );
// Book Genres pagination
add_rewrite_rule( '^books/book-genres/([^/]+)/page/([0-9]+)?$',
'index.php?post_type=book&genre=$matches[1]&paged=$matches[2]', 'top' );
// Movie Genres
add_rewrite_rule( '^movies/movie-genres/([^/]+)/?$',
'index.php?taxonomy=genre&post_type=movie&term=$matches[1]', 'top' );
// Movie Genres pagination
add_rewrite_rule( '^movies/movie-genres/([^/]+)/page/([0-9]+)?$',
'index.php?post_type=movie&genre=$matches[1]&paged=$matches[2]', 'top' );
// Game Genres
add_rewrite_rule( '^games/game-genres/([^/]+)/?$',
'index.php?taxonomy=genre&post_type=game&term=$matches[1]', 'top' );
// Game Genres pagination
add_rewrite_rule( '^games/game-genres/([^/]+)/page/([0-9]+)?$',
'index.php?post_type=game&genre=$matches[1]&paged=$matches[2]', 'top' );
}
add_action( 'init', 'wpse247013_rewrite_rules', 10, 0 );
```
Make sure to flush the rewrite rules by visiting **Settings > Permalinks** after adding this code to your plugin or theme. If you're using a plugin, you can flush the rules programmatically using [register\_activation\_hook](https://codex.wordpress.org/Function_Reference/flush_rewrite_rules).
Custom URLs
-----------
>
> The rewrite rules added above will enable the following new URLs:
>
>
> * <http://example.com/books/book-genres/>{genre-term-slug}
>
> (*lists only books associated with the specified genre-term-slug )*
> * <http://example.com/movies/movie-genres/>{genre-term-slug}
>
> *(lists only movies associated with the specified genre-term-slug )*
> * <http://example.com/games/game-genres/>{genre-term-slug}
>
> *(lists only games associated with the specified genre-term-slug )*
>

I am trying to run string locator plugin to find some strings in my theme directory. but whenever i try to run this plugin, following error ocures
"Warning
The maximum time your server allows a script to run is too low for the plugin to run as intended, at startup 2 seconds have passed"
I have tried to increase max exeecution time for script in php.ini by going to
Xampp control panel click config> php.ini .... but nothing changed.
is there any other way to make this plugin work?
thanks!

Here is a complete example made possible using [`add_rewrite_rule()`](https://codex.wordpress.org/Rewrite_API/add_rewrite_rule). The basic setup for this example is documented first, then we'll get to the real part of the solution using `add_rewrite_rule()`.
Taxonomy and Post Type registration
-----------------------------------
Register the `genre` taxonomy and the `book`, `movie`, and `game` post types *(note that the singular version of each of these names is being used in this example because it's considered a [best practice](https://softwareengineering.stackexchange.com/questions/103720/classes-naming-singular-or-plural))*.
```
// Create taxonomy: genre for post types: book, movie, and game
// https://codex.wordpress.org/Function_Reference/register_taxonomy
add_action( 'init', 'wpse247013_register_taxonomies', 0 );
function wpse247013_register_taxonomies() {
$args = [
'public' => true,
'hierarchical' => false,
'label' => __( 'Genres', 'textdomain' ),
'show_ui' => true,
'show_admin_column' => true,
'query_var' => 'genre',
'rewrite' => [ 'slug' => 'genres' ],
];
register_taxonomy( 'genre', [ 'book', 'movie', 'game' ], $args );
}
// Create post types: movie, book, and game
// https://developer.wordpress.org/reference/functions/register_post_type/
add_action( 'init', 'wpse247013_register_post_types' );
function wpse247013_register_post_types() {
$book_args = [
'label' => __( 'Books', 'textdomain' ),
'public' => true,
'publicly_queryable' => true,
'show_ui' => true,
'show_in_menu' => true,
'query_var' => true,
'rewrite' => [ 'slug' => 'books' ],
'capability_type' => 'post',
'has_archive' => true,
'hierarchical' => false,
'menu_position' => null,
'supports' => [ 'title', 'editor', 'author', 'thumbnail', 'excerpt', 'comments' ],
'taxonomies' => [ 'genre' ],
];
register_post_type( 'book', $book_args );
$movie_args = [
'label' => __( 'Movies', 'textdomain' ),
'public' => true,
'publicly_queryable' => true,
'show_ui' => true,
'show_in_menu' => true,
'query_var' => true,
'rewrite' => [ 'slug' => 'movies' ],
'capability_type' => 'post',
'has_archive' => true,
'hierarchical' => false,
'menu_position' => null,
'supports' => [ 'title', 'editor', 'author', 'thumbnail', 'excerpt', 'comments' ],
'taxonomies' => [ 'genre' ],
];
register_post_type( 'movie', $movie_args );
$game_args = [
'label' => __( 'Games', 'textdomain' ),
'public' => true,
'publicly_queryable' => true,
'show_ui' => true,
'show_in_menu' => true,
'query_var' => true,
'rewrite' => [ 'slug' => 'games' ],
'capability_type' => 'post',
'has_archive' => true,
'hierarchical' => false,
'menu_position' => null,
'supports' => [ 'title', 'editor', 'author', 'thumbnail', 'excerpt', 'comments' ],
'taxonomies' => [ 'genre' ],
];
register_post_type( 'game', $game_args );
}
```
Basic URL Examples
------------------
>
> Based on the setup above, we'll get these URLs out of the box:
>
>
> **Post type archive URLs**
>
>
> * <http://example.com/books/>
> * <http://example.com/movies/>
> * <http://example.com/games/>
>
>
> **Single post type URLs**
>
>
> * <http://example.com/books/>{book-post-slug}
> * <http://example.com/movies/>{movie-post-slug}
> * <http://example.com/games/>{game-post-slug}
>
>
> **Taxonomy Term archive URLs**
>
>
> * <http://example.com/genres/>{genre-term-slug}
>
> *(this archive will include **all** post types, which is not what we're after)*
>
>
>
Handle rewrite rules
--------------------
Rewrite rules must be added in order to limit a particular genre term to a single post type. An additional rule is needed for pagination for each post type.
```
/**
* Add rewrite rules for genre terms limited to book, movie, and game post types.
* Pagination issue fix via http://wordpress.stackexchange.com/a/23155/2807
* @link https://codex.wordpress.org/Rewrite_API/add_rewrite_rule
*/
function wpse247013_rewrite_rules() {
// Book Genres
add_rewrite_rule( '^books/book-genres/([^/]+)/?$',
'index.php?taxonomy=genre&post_type=book&term=$matches[1]', 'top' );
// Book Genres pagination
add_rewrite_rule( '^books/book-genres/([^/]+)/page/([0-9]+)?$',
'index.php?post_type=book&genre=$matches[1]&paged=$matches[2]', 'top' );
// Movie Genres
add_rewrite_rule( '^movies/movie-genres/([^/]+)/?$',
'index.php?taxonomy=genre&post_type=movie&term=$matches[1]', 'top' );
// Movie Genres pagination
add_rewrite_rule( '^movies/movie-genres/([^/]+)/page/([0-9]+)?$',
'index.php?post_type=movie&genre=$matches[1]&paged=$matches[2]', 'top' );
// Game Genres
add_rewrite_rule( '^games/game-genres/([^/]+)/?$',
'index.php?taxonomy=genre&post_type=game&term=$matches[1]', 'top' );
// Game Genres pagination
add_rewrite_rule( '^games/game-genres/([^/]+)/page/([0-9]+)?$',
'index.php?post_type=game&genre=$matches[1]&paged=$matches[2]', 'top' );
}
add_action( 'init', 'wpse247013_rewrite_rules', 10, 0 );
```
Make sure to flush the rewrite rules by visiting **Settings > Permalinks** after adding this code to your plugin or theme. If you're using a plugin, you can flush the rules programmatically using [register\_activation\_hook](https://codex.wordpress.org/Function_Reference/flush_rewrite_rules).
Custom URLs
-----------
>
> The rewrite rules added above will enable the following new URLs:
>
>
> * <http://example.com/books/book-genres/>{genre-term-slug}
>
> (*lists only books associated with the specified genre-term-slug )*
> * <http://example.com/movies/movie-genres/>{genre-term-slug}
>
> *(lists only movies associated with the specified genre-term-slug )*
> * <http://example.com/games/game-genres/>{genre-term-slug}
>
> *(lists only games associated with the specified genre-term-slug )*
>
>
>
