306,752 | <p>I'm hoping someone who knows more than me about PHP and WordPress can help me out with this issue. I have a custom post type with posts I am displaying using the following code:</p>
<pre><code><?php $args = array( 'post_type' => 'upcoming_event', 'posts_per_page' => 3 );

the_content();
echo '</div>';
echo '</div>';
endwhile;
wp_reset_postdata();
?>
</code></pre>
<p>While this works fine in a php file, I'm trying to also make it easily accessible via shortcode. I made the shortcode, and the shortcode works, but every time I place it on a page/post and click "update" or "publish" it sends me to a page with this content printed on it (and only this content printed on it)... But it still saves it, and it still displays fine on the page I saved it on. I know I'm missing something, but I'm so novice at PHP that I don't know what it is.</p>
<p>Here's my shortcode:</p>
<pre><code>// Shortcode for Upcoming Events

306,756 | <p>I noticed recently that when uploading files larger than 7mb to a Wordpress site that I developed, I get an HTTP Error. I've checked some of my PHP variables, and have verified that <code>memory_limit</code> is set to 256M and both <code>post_max_size</code> and <code>upload_max_filesize</code> are set to 128M. After reading <a href="https://wordpress.stackexchange.com/questions/51592/http-error-when-uploading-images">this thread</a>, I tried installing the Default to GD plugin that uses GD as the default WP_Image_Editor class.</p>
<p>After installing the plugin, I'm not having the issue anymore. That said, I'm curious if there's a way to fix this issue with the newer WP_Image_Editor class?</p>
<p>I've also noticed that when I get the HTTP error, I can look at the files attached to the post I added the file to and see that the file is actually there and was successfully uploaded. However, Wordpress seems to have issues displaying it in the Media browser.</p>
<p>I also noticed that if I upload multiple large images over 7mb, I will see the most recent image as the first item in the media library. If I delete that image, I'll see the next most recently uploaded image. For some reason Wordpress is only able to show the most recent image and the thumbnail seems to be broken. However if you navigate to the uploaded file's URI, you can see that the file uploaded successfully.</p>
<p>Does anyone have an idea what's going on with this and is this a known error in Wordpress that's being addressed? Thanks!</p>

It's caused by the image being too large for the memory available. Not the file size as that has compressed data, but the actual width x height x colourdepth.
You can see the full size image because it uploaded fine. You have trouble in the media browser because WP ran out of memory while scaling and cropping the image and so there is no version available for the media browser thumbnail.
I've always found that allocating much more memory to the process fixes it. Or use smaller images (dimensions, not file size).
WordPress will use the higher of WP\_MAX\_MEMORY\_LIMIT and your PHP memory limit, so as long as your hosting allows the easiest thing to do is to set WP\_MAX\_MEMORY\_LIMIT in your wp-config.php:
```
define( 'WP_MAX_MEMORY_LIMIT', '257M' ); // you choose how much
```
The default is 256M for image handling anyway, so if you have problems resizing images it'll need to be something higher than 256M.
As long as your host allows PHP to increase the memory using `@ini_set` then this will work. |

It's caused by the image being too large for the memory available. Not the file size as that has compressed data, but the actual width x height x colourdepth.
You can see the full size image because it uploaded fine. You have trouble in the media browser because WP ran out of memory while scaling and cropping the image and so there is no version available for the media browser thumbnail.
I've always found that allocating much more memory to the process fixes it. Or use smaller images (dimensions, not file size).

As long as your host allows PHP to increase the memory using `@ini_set` then this will work. |
306,816 | <p>I'm using Contact Form 7 and Flamingo to create a consultant registration form on my Wordpress site. By my client request, every submission need to have a registration code (reg_code) which is a combination of submission date and a random number to make it unique.</p>
<p>So I added an hidden input field to my CF7 code with the id "reg_code". On my first try, I used JS to generate a "reg_code" variable right after users visit my site and set the hidden field value to the generated "reg_code" variable. The "reg_code" was saved to CF7 submission successfully but in some cases, when a user didn't submit the form at the first visit time but after a few days, the date part in his "reg_code" would not be correct because that code was generated at his first visit time and cached in the browser.</p>
<p>To avoid this issue, I decided to move the "reg_code" generation function from JS to PHP and the procedure would be like this:</p>
<ol>
<li>Submit button clicked</li>
<li>Use AJAX to call a PHP function which returns a reg_code</li>
<li>Set the hidden field "reg_code" in CF7 value to the returned result</li>
<li>Really perform CF7 submission which saves all CF7 fields to Flamingo</li>
</ol>
<p>This is my JS to trigger the AJAX call before CF7 submit event:</p>
<pre><code>$('.wpcf7-form').on('submit', function (e) {
$.ajax({
type: "post",
dataType: "json",
url: js_object.ajax_url,
data: {
action: "custom_reg_code",
},
success: function (response) {
if (response.success) {
$('#reg_code').val(response.data)
}
else {
console.log('Something wrong')
}
},
error: function (jqXHR, textStatus, errorThrown) {
console.log('fail: ' + textStatus, errorThrown);
},
complete: function() {
}
})
})
</code></pre>
<p>My result: It works only some times. Only some submissions have "reg_code" value, some others have empty "reg_code".</p>
<p>As my guess, the CF7 submit event won't wait for AJAX call to be complete. I tried to add <strong>e.preventDefault()</strong> to the code above to stop the default CF7 submit but no success then. I also tried the CF7 eventListener "wpcf7submit" but still no luck.</p>
<p>Finally, the question is: Is there any way to pause the default CF7 submit event to modify an input field value, then continue the submission process ?</p>
<p>Thank you very much</p>

| I'm using Contact Form 7 and Flamingo to create a consultant registration form on my Wordpress site. By my client request, every submission need to have a registration code (reg\_code) which is a combination of submission date and a random number to make it unique.
So I added an hidden input field to my CF7 code with the id "reg\_code". On my first try, I used JS to generate a "reg\_code" variable right after users visit my site and set the hidden field value to the generated "reg\_code" variable. The "reg\_code" was saved to CF7 submission successfully but in some cases, when a user didn't submit the form at the first visit time but after a few days, the date part in his "reg\_code" would not be correct because that code was generated at his first visit time and cached in the browser.
To avoid this issue, I decided to move the "reg\_code" generation function from JS to PHP and the procedure would be like this:
1. Submit button clicked
2. Use AJAX to call a PHP function which returns a reg\_code
3. Set the hidden field "reg\_code" in CF7 value to the returned result
4. Really perform CF7 submission which saves all CF7 fields to Flamingo
This is my JS to trigger the AJAX call before CF7 submit event:
```
$('.wpcf7-form').on('submit', function (e) {
$.ajax({
type: "post",
dataType: "json",
url: js_object.ajax_url,
data: {
action: "custom_reg_code",
},
success: function (response) {
if (response.success) {
$('#reg_code').val(response.data)
}
else {
console.log('Something wrong')
}
},
error: function (jqXHR, textStatus, errorThrown) {
console.log('fail: ' + textStatus, errorThrown);
},
complete: function() {
}
})
})
```
My result: It works only some times. Only some submissions have "reg\_code" value, some others have empty "reg\_code".
As my guess, the CF7 submit event won't wait for AJAX call to be complete. I tried to add **e.preventDefault()** to the code above to stop the default CF7 submit but no success then. I also tried the CF7 eventListener "wpcf7submit" but still no luck.
Finally, the question is: Is there any way to pause the default CF7 submit event to modify an input field value, then continue the submission process ?
Thank you very much | You could save your AJAX pain and go about this in a different way by placing a hidden field within your form in PHP.
Method 1, with the aid of a plugin
==================================
I generally use the Contact Form 7 Dynamic Text Extension plugin as an easy route to creating custom CF7 tags, which still needs a little coding. You could also go the extra distance and just code your own CF7 tags, but I haven't tried that yet, but I might as an edit to this answer.
With this plugin in place you can put tags into your CF7 form like this:
```
[dynamichidden custom-reg-code “CF7_custom_reg_code”]
```
And in the email pane of CF7's admin page you'd insert [custom-reg-code].
To get it working, just make yourself a matching shortcode to generate your string:
```
function generateRandomString($length = 10) {
return substr(str_shuffle(str_repeat($x='0123456789', ceil($length/strlen($x)) )),1,$length);
}
function wpse306816_CF7_custom_reg_code() {
return date("Ymd") . generateRandomString();
}
add_shortcode('CF7_custom_reg_code', 'wpse306816_CF7_custom_reg_code');
```
Hat-tip to <https://stackoverflow.com/a/13212994/6347850> for the random number generation.
Now you will have a hidden field in your form made up of the current date and a random number that you can use in your form's sent email or save in Flamingo just like any other CF7 field.
Method 2, without the aid of a plugin
=====================================
And a little research has shown that it's even easier to just write your own CF7 tag and not bother with the plugin.
To create a CF7 tag `[serial]`, you register it using `wpcf7_add_form_tag()` on the `wpcf7_init` action hook, passing the name of the tag and the name of a callback function to handle it:
```
add_action( 'wpcf7_init', 'wpse306816_CF7_add_custom_tag' );
function wpse306816_CF7_add_custom_tag() {
wpcf7_add_form_tag(
'serial',
'wpse306816_CF7_handle_custom_tag' );
}
```
And for your case, the callback simply needs to return the serial string value:
```
function generateRandomString($length = 10) {
return substr(str_shuffle(str_repeat($x='0123456789', ceil($length/strlen($x)) )),1,$length);
}
function wpse306816_CF7_handle_custom_tag( $tag ) {
return date("Ymd") . generateRandomString();
}

How would I do that using the loop? Please, help me! Thank you all in advance! | By default WordPress displays your content in a blog format on the homepage.
Using Default Static and Blog Page Settings in WordPress.
WordPress comes with built-in support for creating a custom home page (static front page), and a separate page for blog posts. To use this method, you need to create two new WordPress pages.
The first page is going to be your custom home page.
Next you need to create another page for your blog posts. You can title this page as Blog. A lot of WordPress themes come with different templates, and it is possible that your theme may have a template to be used for blog page. However, if there is no template available in your theme, then you can simply choose default. Don’t forget to disable the comments and trackbacks option on this page as well.
Now we need to get WordPress to use these pages accordingly. To do that go to Setttings » Reading and under the Front page displays option choose A static page. Below that choose the page to be used as the front page and the page for your blog posts. Save your changes, and load your site to review changes.
---
And If you want to create a custom Template that calls the latest 10 posts, You can use the following step (Note - You can use your own HTML for the required layout) -
**Step 1: Page template**
*Create a blank page template named “page-blog.php” and include the following code:*
```
<?php
/*
Template Name: Blog
*/
?>
<?php get_header(); ?>
<div id="content">
<?php query_posts('post_type=post&post_status=publish&posts_per_page=10&paged='. get_query_var('paged')); ?>
<?php if( have_posts() ): ?>
<?php while( have_posts() ): the_post(); ?>
<div id="post-<?php get_the_ID(); ?>" <?php post_class(); ?>>
<a href="<?php the_permalink(); ?>"><?php the_post_thumbnail( array(200,220) ); ?></a>
<h2><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h2>
<span class="meta"><?php author_profile_avatar_link(48); ?> <strong><?php the_time('F jS, Y'); ?></strong> / <strong><?php the_author_link(); ?></strong> / <span class="comments"><?php comments_popup_link(__('0 comments','example'),__('1 comment','example'),__('% comments','example')); ?></span></span>
<?php the_excerpt(__('Continue reading »','example')); ?>
</div><!-- /#post-<?php get_the_ID(); ?> -->
<?php endwhile; ?>
<div class="navigation">
<span class="newer"><?php previous_posts_link(__('« Newer','example')) ?></span> <span class="older"><?php next_posts_link(__('Older »','example')) ?></span>
</div><!-- /.navigation -->
<?php else: ?>
<div id="post-404" class="noposts">
<p><?php _e('None found.','example'); ?></p>
</div><!-- /#post-404 -->
<?php endif; wp_reset_query(); ?>
</div><!-- /#content -->
<?php get_footer(); ?>
```
*Instead of showing 5 posts, you can set posts\_per\_page=10 or whatever works best.*
Note also that the HTML used in this example is rudimentary to keep things simple. You'll probably need to make a few changes to the markup to synchronize with your theme design.
**Step 2: Add New Page**
Once page-blog.php is complete and uploaded to the server, log in to the WP Admin and visit the Add New Page screen. There, create a new page named "Blog" (or whatever you want), and set its Template as "Blog" from the "Page Attributes" panel.
Done!
Now visit the Blog page after publishing and you should see the custom WP\_Query loop working: your latest blog posts will be displayed on the page. |

| I'm trying to upload files with dwg extension to media but when I do that I get an error telling me that uploading files with this extension is not allowed. I tried to upload them via ftp but I cannot see them in my panel afterwards. I've looked for a solution online and tried adding this to my `functions.php`:
```
function custom_upload_mimes ( $existing_mimes=array() ) {
$existing_mimes[‘dwg’] = ‘application/dwg’;
return $existing_mimes;
}
add_filter(‘upload_mimes’,’custom_upload_mimes’);
```
But it didn't change anything. Is there any other way to bypass this file restriction? | Your code should work just fine. The only problem in there is that you’ve set incorrect mime type, I guess...
It should be `image/vnd.dwg`.
So this one should work:
```
function custom_upload_mimes ( $existing_mimes=array() ) {
$existing_mimes['dwg'] = 'image/vnd.dwg';
return $existing_mimes;
}
add_filter('upload_mimes', 'custom_upload_mimes');

Or do I need to simply delete everything and re-upload all the WordPress files? | If you only want to *empty* the site of its *content* (*posts*, *comments*, *terms*, and *meta*) then there's a [wp-cli](https://developer.wordpress.org/cli/commands/site/empty/) command for that:

In that function you can define your criteria in which you'd use the SMTP connection instead of the default.
You can set up your SMTP credentials and server connection info in wp-config.php as constants as follows:
```
/*

* constant ABSPATH is defined.
*/
define( 'SMTP_USER', '[email protected]' ); // Username to use for SMTP authentication
define( 'SMTP_PASS', 'smtp password' ); // Password to use for SMTP authentication
define( 'SMTP_HOST', 'smtp.example.com' ); // The hostname of the mail server

define( 'SMTP_AUTH', true ); // Use SMTP authentication (true|false)
define( 'SMTP_DEBUG', 0 ); // for debugging purposes only set to 1 or 2
```
Once you've added that to your wp-config.php file, you have constants that you can use to connect and send any email via SMTP. You can do this by hooking to the phpmailer\_init action and using that to set up connection criteria using the constants you defined above.
In your specific case, you would want to add some conditional logic in the function to identify the condition in which you want to send via SMTP. Set up your conditional so that only your criteria uses the SMTP connection for the phpmailer, and all others would use whatever is already being used.
Since we don't know what that is from your OP, I've represented it here with a generic `true === $some_criteria`:
```
add_action( 'phpmailer_init', 'send_smtp_email' );
function send_smtp_email( $phpmailer ) {
if ( true === $some_criteria ) {
if ( ! is_object( $phpmailer ) ) {
$phpmailer = (object) $phpmailer;
}
$phpmailer->Mailer = 'smtp';
$phpmailer->Host = SMTP_HOST;
$phpmailer->SMTPAuth = SMTP_AUTH;
$phpmailer->Port = SMTP_PORT;
$phpmailer->Username = SMTP_USER;
$phpmailer->Password = SMTP_PASS;
$phpmailer->SMTPSecure = SMTP_SECURE;
$phpmailer->From = SMTP_FROM;
$phpmailer->FromName = SMTP_NAME;
}
// any other case would not change the sending server
}

Thanks. | The following is a way to handle your question. It is in two parts. First, you would create your connection as constants to be used later. The best way to do this is in wp-config.php. (You mentioned that you're doing this in a custom plugin. If that's something that is to be portable, then you may want to change this to saving setting in the db instead.) Second, you'll apply a function hooked to the phpmailer that WP uses. In that function you can define your criteria in which you'd use the SMTP connection instead of the default.
You can set up your SMTP credentials and server connection info in wp-config.php as constants as follows:
```
/*
* Set the following constants in wp-config.php
* These should be added somewhere BEFORE the
* constant ABSPATH is defined.
*/
define( 'SMTP_USER', '[email protected]' ); // Username to use for SMTP authentication
define( 'SMTP_PASS', 'smtp password' ); // Password to use for SMTP authentication
define( 'SMTP_HOST', 'smtp.example.com' ); // The hostname of the mail server
define( 'SMTP_FROM', '[email protected]' ); // SMTP From email address
define( 'SMTP_NAME', 'e.g Website Name' ); // SMTP From name
define( 'SMTP_PORT', '25' ); // SMTP port number - likely to be 25, 465 or 587
define( 'SMTP_SECURE', 'tls' ); // Encryption system to use - ssl or tls
define( 'SMTP_AUTH', true ); // Use SMTP authentication (true|false)
define( 'SMTP_DEBUG', 0 ); // for debugging purposes only set to 1 or 2
```
Once you've added that to your wp-config.php file, you have constants that you can use to connect and send any email via SMTP. You can do this by hooking to the phpmailer\_init action and using that to set up connection criteria using the constants you defined above.
In your specific case, you would want to add some conditional logic in the function to identify the condition in which you want to send via SMTP. Set up your conditional so that only your criteria uses the SMTP connection for the phpmailer, and all others would use whatever is already being used.
Since we don't know what that is from your OP, I've represented it here with a generic `true === $some_criteria`:
```
add_action( 'phpmailer_init', 'send_smtp_email' );
function send_smtp_email( $phpmailer ) {
if ( true === $some_criteria ) {
if ( ! is_object( $phpmailer ) ) {
$phpmailer = (object) $phpmailer;
}
$phpmailer->Mailer = 'smtp';
$phpmailer->Host = SMTP_HOST;
$phpmailer->SMTPAuth = SMTP_AUTH;
$phpmailer->Port = SMTP_PORT;
$phpmailer->Username = SMTP_USER;
$phpmailer->Password = SMTP_PASS;
$phpmailer->SMTPSecure = SMTP_SECURE;
$phpmailer->From = SMTP_FROM;
$phpmailer->FromName = SMTP_NAME;
}
// any other case would not change the sending server
}
```
This concept is from the following gist on github:

| I am a newbe in wordpress theme development. Can anyone tell me where I should implement the code for any ajax functionalities(say a voting system for posts)? should I write it on a separate plugin or as a custom code in functions.php please do explain your reason, thanks. | Use REST API endpoint instead!
Lets register an endpoint at `/wp-json/tomjn/v1/test`, that calls `tomjn_rest_test()` when you hit it:
```
add_action( 'rest_api_init', function () {
register_rest_route( 'tomjn/v1', '/test/', array(
'methods' => 'GET',
'callback' => 'tomjn_rest_test'
) );
} );
```
Now lets add the `tomjn_rest_test` function:
```
function tomjn_rest_test( $request ) {
return "moomins";
}
```
Now when we visit tomjn.com/wp-json/tomjn/v1/test we get:
[](https://i.stack.imgur.com/fpAf1.png)
Now we can grab it on the frontend:
```
<script>
jQuery.ajax({
url: <?php echo wp_json_encode( esc_url_raw( rest_url( 'tomjn/v1/test' ) ) ); ?>
}).done(function( data ) {
// do something
jQuery( '#tomsword' ).text( data );
});
</script>
```
That code looks for a `<div id="tomsword">` and sets the contents to whatever the endpoint returned.
### But Where Do I Put The Code? Theme or Plugin?
You can register you endpoints in a plugin or theme, just remember:
* themes determine how your site looks
* plugins determine what you site can do
**Voting sounds like functionality, not decoration, and should go in a plugin.**
If you put it in a theme, then that functionality is forever trapped in that theme unless a developer manually extracts it. Any voting data is unavailable as soon as the user changes the theme |

Also curious about any potential performance issues involved. | Here's a REST API recipe for **latest post per site on a multi-site**, for relatively few sites:
* Use `get_sites()`,
* loop over sites and switch to each site,
* query latest post on each site,
* collect data,
* order data by *utime*,
* serve data
**Example REST Routes**
```
https://example.com/wp-json/wpse/v1/latest-post-per-site

```
<?php

wp_reset_postdata();

| I have a custom page template defined and working properly.
On this specific page, I want to list a lot of links, and paginate them, to display 100 links per page.
Here is the code in my template file, working exactly like I want
```
<div class="container">
<ul class="row listing-items">
<?php

$wp_query = new WP_Query( $custom_args );

endwhile;
wp_reset_postdata();
}
?>
</ul>
```
Now, for SEO purposes, I want to add in my header rel Next and Prev, so Google understand the pagination and can understand which page is the current one, and which page is next and prev.
Here is my code in functions.php
```
function rel_next_prev() {
global $paged;
if ( get_previous_posts_link() ) {
echo '<link rel="prev" href="'.get_pagenum_link( $paged - 1 ).'" />';
}
if ( get_next_posts_link() ) {
echo '<link rel="next" href="'.get_pagenum_link( $paged + 1 ).'" />';
}
}
add_action( 'wp_head', 'rel_next_prev' );
```
Unfortunately, this is partially working. I always get the Rel Prev link in the header, but is not currently based on the query I did.
Let me explain:
When my query is set, I have 19 pages, under this format:
```
http://localhost:3000/villes/page/2/
```
So If I change the URL to be (404)
```
http://localhost:3000/villes/page/222/
```
I still get rel Prev with 221 in the header.
*So to resume:*
**How do I properly set rel next/prev in the header based on the current query I'm doing?**
Thanks! | After a huge night overthinking this, and thanks to Joost de Valk (Yoast SEO plugin author), I found the solution.
As per this thread: <https://github.com/Yoast/wordpress-seo/issues/437> , what I want to achieve the way I do, **is undoable, or at least, a very bad practice.**
If you want your custom query to have the default pagination and rel next prev in the header, you need to call it before `get_header();`
THEORIC SOLUTION
================
To make your custom query work with default WP and Yoast functions, you need to:
1. Put your query **BEFORE** `get_header();`
2. Be sure your query has the default name provided by WP, which is `$wp_query`
3. That being said, you will need to create a specific page template for your query, so you can set your query before getting the header.
PRACTIC SOLUTION
================
For the previous code I had, which was working with `get_template_part();`.
1. Create a custom page-template, refering to the page ID or the page slug. More on this here: <https://developer.wordpress.org/themes/template-files-section/page-template-files/>
2. Set your custom query before the `get_header();` function.
3. Be sure to re-adapt your code, so it displays the way you want.
Here is my code, which is working as expected. **Be sure to keep the** `rel_next_prev();` **function I placed in my functions.php**
Final Result:
```
<?php
$paged = ( get_query_var('paged') ) ? get_query_var('paged') : 1;
$custom_args = array(
'post_type' => 'page',
'posts_per_page' => 90,

Can I change the URL myblog.com/author/me directly to myblog.com, without a 301 redirect? Thanks! | Disabling the author pages is a 'good thing'. A 'bad actor' can enumerate your users, or even get your admin user (which is user id 1) with a simple query on any page. So redirecting author requests is a good idea - and a good security measure. (As is never having a user called 'admin', especially if it has admin privileges.)
For instance, an attacker could use the xmlprc.prg page to post multiple requests to any page. They could look through x number of author id's and get a list of the login names of all the user ids. Then use that list to try to get into the admin pages.
I suspect that the Yoast plugin is redirecting author requests. The code to redirect author requests to the home page will look like this:
```
function wp_redirect_if_author_query() {
$is_author_set = get_query_var( 'author', '' );
if ( $is_author_set != '' && !is_admin()) {
wp_redirect( home_url(), 301 ); // send them somewhere else
exit;
}
}
add_action( 'template_redirect', 'wp_redirect_if_author_query' );
```
Put a variation of this code (with the redirect you want to have) in your Child Theme's functions.php file. Or in a simple plugin. (I have a customized personal plugin where I do all sorts of standard settings, including those related to security.) You might need to give a higher priority to the add\_action (the optional third parameter, which defaults to 10) to override what the Yoast plugin is doing. |
307,155 | <p>I could use another set of eyes on this one...its been a little bit of time since I last created a Wordpress theme. I can't figure out what I'm doing wrong here.</p>
<p>I created a custom post type (journal) and set up a loop on a custom template, which I set on the homepage.<br>
I then have single-journal.php template for the individual post types.<br>
The Journal CPT posts show up fine in my home page template, the url/permalink looks correct on inspection. However, when I click through on any of them (I have three at the moment), they all show the content of the latest post. The url/permalink comes up correct in the url bar too, but the content is wrong.
Heres some code:

| I could use another set of eyes on this one...its been a little bit of time since I last created a Wordpress theme. I can't figure out what I'm doing wrong here.
I created a custom post type (journal) and set up a loop on a custom template, which I set on the homepage.
I then have single-journal.php template for the individual post types.
The Journal CPT posts show up fine in my home page template, the url/permalink looks correct on inspection. However, when I click through on any of them (I have three at the moment), they all show the content of the latest post. The url/permalink comes up correct in the url bar too, but the content is wrong.
Heres some code:
This is the loop on the home page template:
```
<div class="post-slider">
<?php $args = array('post_type' => 'journal',
'posts_per_page' => -1,
'post_status' => 'publish',
'orderby' => 'date',
'order' => 'DESC');
$loop = new WP_Query($args);
if ( $loop->have_posts() ) :
while ( $loop->have_posts() ) :
$loop->the_post(); ?>
<div class="post-card">
<div class="post-card-inner">
<?php if ( has_post_thumbnail() ) {the_post_thumbnail();} ?>
<a href="<?php the_permalink(); ?>"
rel="bookmark"
title="Permanent Link to <?php the_title_attribute(); ?>">
<p><?php the_title(); ?></p>
</a>
</div>
</div>
<?php
// End the loop.
endwhile;
else:
?>
<h1>No posts here!</h1>
<?php endif;
wp_reset_postdata(); ?>
</div>
```
This is the loop from single-journal.php:
```
<?php $args = array('post_type' => 'journal',
'showposts' => 1,
'post_status' => 'publish',
'orderby' => 'date',
'order' => 'DESC');
$loop = new WP_Query($args);
if ( $loop->have_posts() ) : while ( $loop->have_posts() ) : $loop->the_post(); ?>
<?php get_template_part( 'content', get_post_format() ); ?>
<!--- Add authorname taxonomy -->
<?php the_terms( $post->ID, 'authorname', 'Author: ', ', ', ' ' ); ?>
<hr/>
<nav class="nav-single">
<h3 class="assistive-text"><?php _e( 'Post navigation', 'twentytwelve' ); ?></h3>
<span class="nav-previous"><?php previous_post_link( '%link', '<span class="meta-nav">' . _x( '←', 'Previous post link', 'twentytwelve' ) . '</span> %title' ); ?></span>
<span class="nav-next"><?php next_post_link( '%link', '%title <span class="meta-nav">' . _x( '→', 'Next post link', 'twentytwelve' ) . '</span>' ); ?></span>
</nav><!-- .nav-single -->
<?php comments_template( '', true ); ?>
<?php endwhile; endif; wp_reset_postdata();// end of the loop. ?>
```
This is the custom post type:
```
/*
** Journal Entry
**
*/
function journal_entry() {
// creating (registering) the custom type
register_post_type( 'journal',
array(
'labels' => array(

/* this adds your post categories to your custom post type */
//register_taxonomy_for_object_type( 'category', 'stories' );
/* this adds your post tags to your custom post type */
//register_taxonomy_for_object_type( 'post_tag', 'custom_post_faq' );
}
add_action( 'init', 'journal_entry');
function journal_taxonomy() {
register_taxonomy(
'journal_categories', //The name of the taxonomy. Name should be in slug form (must not contain capital letters or spaces).
'journal', //post type name
array(
'hierarchical' => true,
'label' => 'Custom Categories', //Display name
'query_var' => true,
'rewrite' => array(
'slug' => 'journal-categories', // This controls the base slug that will display before each term
'with_front' => false // Don't display the category base before

)
);
}
add_action( 'init', 'journal_taxonomy');
``` | You shouldn't be using custom queries in these templates. The main query (using `have_posts();`, `the_post();` etc. without `$loop`) is already set up with the correct posts for these templates.
Look at the custom query you're using on the single template:
```
$args = array('post_type' => 'journal',
'showposts' => 1,
'post_status' => 'publish',
'orderby' => 'date',
'order' => 'DESC');
$loop = new WP_Query($args);
```
That's a query for the latest journal post. So of that's what you're going to see when you use `$loop->the_post()`. Also, `showposts` is deprecated. Use `posts_per_page` instead.
So this:
```
if ( $loop->have_posts() ) : while ( $loop->have_posts() ) : $loop->the_post(); ?>
```
Needs to be:
```
if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>

---
// Edit and Update
Thank you all for your comment, I believe I gave the half of the idea of what I really need and how I'm trying to achieve it. So I'll begin with the idea/scenario.
General Idea:
1. I have Custom post type, let's call it "assignment" and "projects".
2. I have users on the site, let's call them "teacher" and "student".
3. multiple teachers can assign "assignment" and "projects" to multiple students.
4. Now, I have a "Directory" page, on which I wish to display all (teacher, student, assignments, and projects).
5. On the frontend, I wish to display each cpt entry and users in thumbnail view like the 4x4 grid.
Now, I have create a page-template called `directory.php` and used the following loop to display only cpt `assignment` and `projects`.
```
$args = array(
'post_type' => array('assigment', 'project'),
'post_status' => 'publish',
'order' => 'ASC'
);
$query = new WP_query( $args );
```
and looped it like this
```
<?php if ( $query->have_posts() ) : ?>
<?php
while ( $query->have_posts() ) :
$query->the_post();
get_template_part( 'template-parts/content', get_post_type() );
endwhile;
the_posts_navigation();
else :
get_template_part( 'template-parts/content', 'none' );
endif;
wp_reset_postdata();
?>
```
the code is working, but please focus on the syntax error if any. now the part of users. I wrote it like this.
```
$user = new WP_User_Query(array('role'=> 'teacher'));
if (!empty($user)) {
foreach ($user as $teacher) {
echo $teacher->first_name;
}
}
```
you get the basic idea of how I can use the users.
**The main Question**
How can I merge Users within the post loop, so users and posts display in a grid of 4x4 and order by timestamps?
For example, we have the following with the date of creation.
Teach A ( 10 Jun, 2018 )
Teach B ( 12 Jun, 2018 )
Stud C ( 15 Jun, 2018 )
Assign 1 ( 16 Jun, 2018 )
Assign 2 ( 18 Jun, 2018 )
Stud D ( 20 Jun, 2018 )
Proj 1 ( 22 Jun, 2018 )
and then I display in the 4x4 grid like this.
Teach A Teach B Stud C Assign 1
Assign 2 Stud D Proj 1

For this, I'm going to use `get_posts()` over `WP_Query()`, and `get_users()` over `WP_User_Query()` to achieve this.
The code itself should be self explanatory.
```
// Get a list of users
$users = get_users ();
// Get an array of posts. Don't forget to set the args
$posts = get_posts();
// Let's merge these two
$users_posts = array_merge( $users, $posts );
// Now, let's sort both of them based on
// their dates. a user object holds the date
// as `user_registered`, while a post object
// holds the date as `post_date`. We use the
// usort() function to do so.
usort( $users_posts, "sort_users_and_posts" );
// Function to sort the array
function sort_users_and_posts( $a, $b ){
// Here's the tricky part. We need to get the
// date based on the object type, and then compare them.
// Get the date for first element
if( $a instanceof WP_User ){
$first_element_date = strtotime ( $a->user_registered );
} else {
$first_element_date = strtotime ( $a->post_date );
}
// Get the date for second element
if( $b instanceof WP_User ){
$second_element_date = strtotime ( $b->user_registered );
} else {
$second_element_date = strtotime ( $b->post_date );
}
// Now let's compare the dates
// If the dates are the same
if ( $first_element_date == $second_element_date ) return 0;
// If one is bigger than the other
return ( $first_element_date < $second_element_date ) ? -1 : 1;
}
// Now, we run a foreach loop and output the date.
// We need to check again whether the object is an
// instance of WP_Post or WP_User
foreach ( $users_posts as $object ) {
if( $object instanceof WP_Post ){
// This is a post
} else {
// This is a user
}
}

307,310 | <p>We recently implemented a stock quote system, where a user can enter a stock symbol and it will return all sorts of financial values.</p>
<p>I have a template made up that displays the financial widgets, and when a user enters a ticker symbol it runs some JS with the callback url being my template. In this example, it is something like this.</p>
<p><a href="https://www.stocktrades.ca/quote/?qm_symbol=AAPL" rel="nofollow noreferrer">https://www.stocktrades.ca/quote/?qm_symbol=AAPL</a></p>
<p>What my issue is, is the title is currently blank. When a user inputs a symbol, the page title in the browser is simply “Quote -” Instead, I want it to be “Quote – XXXX” with XXXX being the stock ticker they entered.</p>
<p>What is the easiest way to go about this? I know it’s probably really simple, but I am stumped</p>

| We recently implemented a stock quote system, where a user can enter a stock symbol and it will return all sorts of financial values.
I have a template made up that displays the financial widgets, and when a user enters a ticker symbol it runs some JS with the callback url being my template. In this example, it is something like this.
<https://www.stocktrades.ca/quote/?qm_symbol=AAPL>
What my issue is, is the title is currently blank. When a user inputs a symbol, the page title in the browser is simply “Quote -” Instead, I want it to be “Quote – XXXX” with XXXX being the stock ticker they entered.
What is the easiest way to go about this? I know it’s probably really simple, but I am stumped | [The page link field](https://www.advancedcustomfields.com/resources/page-link/) actually stores the post ID, which gets formatted internally by the `get_field` function on output. The 3rd argument for `get_field` lets you disable that output formatting so you just get the ID back, which you can then use to get title and permalink for that post:
```
$post_id = get_field( 'bookitall_roomstype', false, false );
if( $post_id ):
echo get_the_permalink( $post_id );
echo get_the_title( $post_id );
endif;

Thanks for any advice | You can use `user_register` hook
```
add_action( 'user_register', 'my_registration', 10, 2 );
function my_registration( $user_id ) {
// get user data
$user_info = get_userdata($user_id);
// create md5 code to verify later
$code = md5(time());
// make it into a code to send it to user via email
$string = array('id'=>$user_id, 'code'=>$code);
// create the activation code and activation status
update_user_meta($user_id, 'account_activated', 0);
update_user_meta($user_id, 'activation_code', $code);
// create the url
$url = get_site_url(). '/my-account/?act=' .base64_encode( serialize($string));
// basically we will edit here to make this nicer
$html = 'Please click the following links <br/><br/> <a href="'.$url.'">'.$url.'</a>';
// send an email out to user
wp_mail( $user_info->user_email, __('Email Subject','text-domain') , $html);
}
```
You can check for `$_GET['act']` and then activate if that's a valid key by updating the meta value `account_activated`. You can use `wp_authenticate_user` hook to verify activation status every time when user tries to login.
Snippet to validate:
```
add_action( 'init', 'verify_user_code' );
function verify_user_code(){
if(isset($_GET['act'])){
$data = unserialize(base64_decode($_GET['act']));
$code = get_user_meta($data['id'], 'activation_code', true);
// verify whether the code given is the same as ours
if($code == $data['code']){
// update the user meta
update_user_meta($data['id'], 'is_activated', 1);
wc_add_notice( __( '<strong>Success:</strong> Your account has been activated! ', 'text-domain' ) );
}

This is setting `$table` to a PHP [constant](http://php.net/manual/en/language.constants.php) `wp_save`. If I had to guess I'd say you don't actually have a constant by that name, and just meant to set the table name to `wp_save`. To do that you need to put the table name between quotes, so that it's a [String](http://php.net/manual/en/language.types.string.php):
```
$table = 'wp_save';
```
However, given that WordPress users can change the `wp_` prefix in the database to whatever they like, you should use `$wpdb->prefix` to use the correct prefix as set by the user:
```
$table = $wpdb->prefix . 'save';
```
Before diving in too deep on building a plugin though, I'd suggest brushing up on the basics of PHP so that you know the difference between the different types of values, like Strings and Constants.

| I have registered a widget in order to allow users to filter posts by category or write something in the search box, the problem is that my 'blog' page is 'home.php' because it is a single-page-site (in index.php I am loading all the content), when I pick up a category or click on search button it redirects to index.php, instead of remaining in home.php.
How can I change that behaviour? | ```
$table = wp_save;
```
This is setting `$table` to a PHP [constant](http://php.net/manual/en/language.constants.php) `wp_save`. If I had to guess I'd say you don't actually have a constant by that name, and just meant to set the table name to `wp_save`. To do that you need to put the table name between quotes, so that it's a [String](http://php.net/manual/en/language.types.string.php):
```
$table = 'wp_save';
```
However, given that WordPress users can change the `wp_` prefix in the database to whatever they like, you should use `$wpdb->prefix` to use the correct prefix as set by the user:
```
$table = $wpdb->prefix . 'save';
```
Before diving in too deep on building a plugin though, I'd suggest brushing up on the basics of PHP so that you know the difference between the different types of values, like Strings and Constants. Ultimately everything you're going to be doing in the back-end is PHP, and the fundamentals don't differ just because it's WordPress. |

Not sure where it is coming from. | [Since version 4.1.6](https://wordpress.org/support/topic/how-to-disable-mshots-service/#post-12939728), Akismet has a filter which [allows you to disable these "mShots"](https://wordpress.org/support/topic/how-to-disable-mshots-service/#post-12944077) (the site preview popups):
```
<?php
function disable_akismet_mshots( $value ) {

Any ideas why? | Your code looks OK and it should work just fine. But there are some things you can (and you should) fix.
1. You don't use absolute URL for your fallback image
-----------------------------------------------------
You pass `/wp/wp-content/themes/klicknet-theme/images/testbild.png` as src of your image. It would be much better and more secure if you'd use WP functions in there. For example like so:
```
<img src="<?php bloginfo('template_url'); ?>/images/testbild.png">
```
2. You don't escape the title properly
--------------------------------------
In your fallback image you use `the_title()` in title attribute. But you don't escape it as an attribute. If the title contains `"` character, it will break your HTML. Another problem is that the title can contain HTML tags, and they will be printed in your attribute.
If you want to use title as attribute, you should use [`the_title_attribute`](https://codex.wordpress.org/Function_Reference/the_title_attribute) function instead. So the fixed version of that line can look something like this:
```
<img src="<?php bloginfo('template_url'); ?>/images/testbild.png" alt="testbild" width="334" height="259" title="<?php the_title_attribute( array( 'before' => 'Bild: ', 'after' => '' ) ); ?>">

Keep in mind this will change all your Post URLs, so you'll need to add redirects. Also keep in mind small tweaks to permalinks like this don't often give you a big SEO boost so depending on how many posts you would need to redirect, it may be worth investing more effort into optimizing the on-page content rather than changing permalinks. |

In `tag.php` I display all posts with that specific tag via a `WP_Query` and I'm trying to implement the pagination for that listing (using `paginate_links()`). Page links seem to be outputted correctly. Also the first page looks good.
What I don't understand is that when I go on to the next tag page (or to any of the page links outputted from my `tag.php` template e.g. `http://127.0.0.1/wp_site/tag/test_tag/page/2/`) the content from `index.php` is being displayed.

This is my theme's file-structure so far:
[](https://i.stack.imgur.com/PzHKj.png) | Overall CODE issues:
--------------------
Your CODE is so wrong in so many ways that I shouldn't even attempt to address them here. I suggest you study [Official WordPress Theme Handbook](https://developer.wordpress.org/themes/) properly before doing these sort of customizations.
For the sake of the context, I'm ignoring other issues within your CODE and touching only the issues below:
1. Why `index.php` template is being loaded?
--------------------------------------------
First of all, you are getting wrong pagination from your erroneous CODE (check the explanation below). So apart from the first tag page, all the other tag pages are nonexistent (i.e. you need to add more posts to the tag to get more tag pages).
Secondly, According to WordPress Template loading rules, `404.php` template should be loaded for those non-existing tag pages (as you probably know, in HTTP, 404 is the **Page Not Found Error CODE**). However, since you don't have a `404.php` template in your theme, `index.php` template is being loaded, as it is the **ultimate fallback template** in a WordPress theme.
Now, if you create a `404.php` template, then you'll see that it'll be loaded instead of `index.php` for those non-existing tag pages.
Study [WordPress Template Hierarchy](https://developer.wordpress.org/themes/basics/template-hierarchy/) properly for a better understanding of how different templates are loaded for different content.
2. Fixing the wrong pagination:
-------------------------------
As I said above, you're getting nonexistent tag page numbers within your pagination. To remove those nonexistent page numbers from the pagination, you need to delete the
```
'total' => $post_query->max_num_pages
```
line from the `paginate_links` function call in `tag.php` template file.
The reason is:
1. `$post_query` is your custom query, not the main query that should determine the number of pages the tag archive has. You even used `wp_reset_postdata()` before `paginate_links` function call, so no reason to use that variable here.
2. The `total` parameter of the `paginate_links` function by default gets the value of the main WP\_Query's `max_num_pages` property. So deleting it will automatically provide the correct value for the pagination from the main WP\_Query object.
3. Pagination without new `WP_Query`:
-------------------------------------
In the comments you said:
>
> The reason why I did this is because I didn't know how to generate the type of pagination I needed (`<Prev 1 2 3 Next>` style) via `paginate_links()`, with the main query.
>
>
>
Well, you don't need a completely new `WP_Query` just for a different pagination style. In fact, the `paginate_links()` function don't need the main `WP_Query` object at all!
So all you need for your desired pagination style is:
```
echo paginate_links( array(
'end_size' => 2,
'mid_size' => 1,
'prev_text' => __( '<< Previous page', 'text-domain' ),
'next_text' => __( 'Next page >>', 'text-domain' )
) );
```
All the other values are being collected by default (including the main `WP_Query` object)! So you can remove your new `WP_Query` object in the `tag.php` template entirely. Check the [`paginate_links` documentation](https://developer.wordpress.org/reference/functions/paginate_links/).
Having said that, there can be only one more thing you may want (judging from your comments):
4. Control the number of posts per tag page:
--------------------------------------------
You don't need a new `WP_Query` for this either. This can be easily achieved from the following CODE in `functions.php`:
```
function tag_post_per_page_filter( $query ) {
if ( $query->is_main_query() ) {
if ( $query->is_tag ) {
$query->set( 'posts_per_page', 3 );
}
}
}
add_action('pre_get_posts','tag_post_per_page_filter');
```
Basically it sets the `posts_per_page` to `3` in the main `WP_Query` object for the tag pages. That's all. |

| I've been trying to solve this myself for hours but I can't figure out where I am going wrong.
I have a custom registration form on my website and I would like to add a checkbox for users to sign up for the newsletter.
I went through the [Mailpoet Docs](https://beta.docs.mailpoet.com/article/195-add-subscribers-through-your-own-form-or-plugin) and tried everything that they describe there but something is not working for me.
The user is being signed up successfully but never gets added to my mainling list. Here's my code
```
function newsletterSignUp(){
$subscriber_data = array(
'email' => sanitize_text_field($_POST['email']),
'first_name' => sanitize_text_field($_POST['first_name']),
'last_name' => sanitize_text_field($_POST['last_name'])
);
$list = \MailPoet\API\API::MP('v1')->getLists()[0][id];
//Returns the ID of the list that I want to assign subscribers to
try {
$subscriber = \MailPoet\API\API::MP('v1')->addSubscriber($subscriber_data, $list, $options);
} catch(Exception $exception) {
// return $exception->getMessage();
}
}
```
I am calling this function like this:
```
if(isset($_POST['submit'])){
// Some other code to sign up the user
if(isset($_POST['subscribe'])){ //The name of my checkbox input
newsletterSignUp();
}
}
```
Any help will be greatly appreciated!! | This is probably what you are looking for ..
```
add_filter( 'wp_nav_menu_objects', 'add_menu_parent_class' );
function add_menu_parent_class( $items ) {
$parents = array();
foreach ( $items as $item ) {
if ( in_array('current-post-ancestor', $item->classes) ) {
$parents[] = $item->menu_item_parent;
}
}
foreach ( $items as $item ) {
if ( in_array( $item->ID, $parents ) ) {
$item->classes[] = 'current-menu-ancestor';
}
}
return $items;
}
```
It will add a class to **current post ancestor** menu item parent. I have tried this in my theme and it is working perfectly. |

**This is what happens**
[](https://i.stack.imgur.com/0Po9Y.png) | I did have the same issue. And I wasted enough time for the answer.
At first be sure that:
The ajax request isn't failed and happens. So, check:
1. Is acf\_form\_head() before get\_header() and run before any html is output?
2. Does your theme contain call to wp\_head()?
3. Does your theme contain call to wp\_foot()?
4. Are your deferring the loading of JavaScript or otherwise altering the way that JavaScript is loaded on the page?
(Look at [this ACF support topic](https://support.advancedcustomfields.com/forums/topic/my-acf_form-is-saving-to-the-database-but-not-showing-up-in-the-admin-panel-unde/) too. If you use acf\_form() for creating new user look at [this topic](https://support.advancedcustomfields.com/forums/topic/create-new-user-with-acf_form/)).
But in my case the root was is\_admin() in this line into the 'acf/validate\_value' hook:
```
if ( ! $valid || is_admin() ) { return $valid; }
```
**Because is\_admin() returns 'true' by AJAX requests**. As a result, the validate function didn't work.
Hope it will helpfully for somebody. |

| I’m looking to add Instagram to my follow buttons, and on the settings pages it tells me:
You can setup Instagram, YouTube, Snapchat, and other buttons in an AddToAny Follow widget.
Add the “AddToAny Follow” widget in Customize or Widgets.
But in the AddToAny Follow Widget i’ve got linkedin, twitter and facebook. No trace of instagram, that is what I’m trying to add. (<https://imgur.com/a/FEXOQYI>)
What am I not understanding here? | I did have the same issue. And I wasted enough time for the answer.
At first be sure that:
The ajax request isn't failed and happens. So, check:
1. Is acf\_form\_head() before get\_header() and run before any html is output?
2. Does your theme contain call to wp\_head()?
3. Does your theme contain call to wp\_foot()?
4. Are your deferring the loading of JavaScript or otherwise altering the way that JavaScript is loaded on the page?
(Look at [this ACF support topic](https://support.advancedcustomfields.com/forums/topic/my-acf_form-is-saving-to-the-database-but-not-showing-up-in-the-admin-panel-unde/) too. If you use acf\_form() for creating new user look at [this topic](https://support.advancedcustomfields.com/forums/topic/create-new-user-with-acf_form/)).
But in my case the root was is\_admin() in this line into the 'acf/validate\_value' hook:
```
if ( ! $valid || is_admin() ) { return $valid; }
```
**Because is\_admin() returns 'true' by AJAX requests**. As a result, the validate function didn't work.
Hope it will helpfully for somebody. |

307,930 | <p>Problem:</p>
<ul>
<li>I need to associate to every PostType a Company(done with Taxonomy, taxonomy is a huge list of Companies)</li>
<li>A company can be a Producer or a Developer</li>
<li>I need to Select a Producer on the PostType</li>
<li>I need to Select a Developer on the PostType</li>
</ul>
<p>As you understand you can have the same Company as Developer and Producer</p>
<p><strong>Solution ?</strong></p>
<p>Unfortunately i find myself like a fish out of water. Wordpress is the perfect CMS for this Job but for this task, ehmmm, i dont know :/
According my background i can associate a Company to a Post Type (Company will be the Taxonomy). But after ? How to do an intermediate Association (every Company can be a Developer, Publisher or Both) ?</p>
<p>P.S I Dont need meta fields (i need to insert at least 2000 companies if not more than that, custom fields will slow down hard i think the queries if i start to search a developer who has done x PostType)</p>
<p>Thanks in advance to each of you for your time, I do not owe you a beer, I owe you a ticket for the World Cup final if you give me a hand, I'm banging my head against the wall two days for that ...... :/ :D</p>

308,021 | <p>I'm trying to add a class to list blocks (<code>core/list</code>) in Gutenberg. Unfortunately, it looks like because some blocks like lists and paragraphs don't have the standard default class name of <code>wp-block-{name}</code> they can't be renamed using the <a href="https://wordpress.org/gutenberg/handbook/extensibility/extending-blocks/#blocks-getblockdefaultclassname" rel="noreferrer"><code>blocks.getBlockDefaultClassName</code></a> filter.</p>
<p>To get around that, I've used the <code>blocks.getSaveContent.extraProps</code> filter, which seems to enable me to add a class to ALL the blocks that don't already have classes.

}
wp.hooks.addFilter(
'blocks.getSaveContent.extraProps',

addBlockClassName
);

the wp.domReady() makes sure that it loads when it should and applies the changes
```
wp.domReady( () => {
wp.blocks.registerBlockStyle( 'core/list', {
name: 'custom-list-style',
label: 'Custom list style',
isDefault: true
} );
} );

308,126 | <p>I am wondering whether it is possible to automatically add a class to a series of links based on the link text.</p>

| Is there any way to change the order of filters for e.g. the\_content before they are applied? What I currently have is the following ideas:
```
/**
* Print all filters for some hook.
*/
function print_filters_for( $hook = '' ) {
global $wp_filter;
if( empty( $hook ) || !isset( $wp_filter[$hook] ) )
return;
print '<pre>';
print_r( $wp_filter[$hook] );
print '</pre>';
}
add_action('template_redirect','print_filters');
function print_filters() {
print_r(print_filters_for('the_content'));die;
}
```
This gives me the filters, but I can not think of any comfortable way to change their priorities.
```
add_filter( 'the_content', 'my_content_filter_priority_reorder', 0 );
function my_content_filter_priority_reorder($the_content) {
// reorder filter priorities
return $the_content;
}
```
Has anybody already had this problem and knows how to possibly change this? | If you know the existing callback and priority you can just remove the filters and then add again at a different priority:
```
remove_filter( 'the_content', 'convert_smilies', 20 );
add_filter( 'the_content', 'convert_smilies', 30 );
remove_filter( 'the_content', 'capital_P_dangit', 11 );
add_filter( 'the_content', 'capital_P_dangit', 20 );

| I discovered after much painful debugging that requests to the the WP HTTP API (in this case, though `wp_remote_request()`) always ended up as `GET` method after being redirected, even if the method was something else in the initial request (in my case `PURGE` as used by the [Varnish HTTP Purge plugin](https://wordpress.org/plugins/varnish-http-purge/))

`browser_redirect_compatibility()` is pretty simple:
```

Affects Apache but not Nginx?
-----------------------------
This seems relevant: My local dev environment uses MAMP and the sites is hosted through Apache, and this insane problem is triggered.
Our live site uses a Nginx->Varnish->Nginx setup, where for whatever reason, the same redirects were never `302` at all, but instead were `301` and thus worked correctly (they stayed as `PURGE` at the redirected location, which was the `https` version of the URL, rather than the `http` version).
So my recommendtaions to anyone having this problem:
----------------------------------------------------
* Switch to Nginx completely as it seems to not use 302 for such redirects. Apache sux.
* Look for sources of 302 errors and reconfigure your server to use 301 instead
* Look for ways to avoid triggering redirects in the first place! (in our case, making sure the URLs were already `https` to start is an obvious improvement and will make our logs cleaner) |

| I am creating a comparison table and the issue is in while loop i am not able to put the `"tr"` in proper place. I need layout like this
```
<table>
<tr>
<td>post title 1</td>
<td>post title 2</td>
<td>post title 3</td>
</tr>
<tr>
<td>post content 1</td>
<td>post content 2</td>
<td>post content 3</td>
</tr>
<tr>
<td>post author 1</td>
<td>post author 2</td>
<td>post author 3</td>
</tr>
</table>
```
How can i achieve that it's seems like no option see my code below
```
<div class="acadp">
<table>
<tr>
<?php while( $acadp_query->have_posts() ) : $acadp_query->the_post(); ?>
<td><?php the_title(); ?></td>
<td><?php the_content(); ?></td>
<td><?php the_author(); ?></td>
<?php endwhile; ?>
<tr>
</table>
</div>
<?php wp_reset_postdata(); ?>
``` | ```
<div class="acadp">
<?php
$compare =[];
while( $acadp_query->have_posts() ) {
$acadp_query->the_post(); $post_meta = get_post_meta( $post->ID );
$category = wp_get_object_terms( $post->ID, 'acadp_categories' );
$compare['Title'][] = get_the_title();
$compare['Manufacturer'][] = $category[0]->name;
$compare['Image'][] = get_the_acadp_listing_thumbnail($post_meta);
if( count( $fields ) ){
foreach( $fields as $field ) {
$value = $post_meta[ $field->ID ][0];
$compare[$field->post_title][] = $value;
}
}
$compare['URL'][] = "<a href='".get_the_permalink()."' class='btn btn-primary'>View Details</a>";
}
?>
<table class="table table-bordered">
<?php foreach ($compare as $feature => $value): ?>
<tr>
<th><?php echo $feature; ?></th>
<td><?php echo implode("</td><td>",$value); ?></td>
</tr>
<?php endforeach; ?>
</table>
</div>
<!-- end of the loop -->

How do I go about trimming white space from beginning and end of a search term? | I came across the same problem.
In my opinion, this should be the default search behavior in WP.
The solution is to filter the array of parsed query variables.
See the documentation [here](https://developer.wordpress.org/reference/hooks/request/).
Add this to the `functions.php` file in your theme directory.
```
add_filter('request', function ($query_vars) {
if (!is_admin() && !empty($query_vars['s'])) {
$query_vars['s'] = trim($query_vars['s']);
}
return $query_vars;
});

308,470 | <p>I'm fairly new to wordpress and the content management system. I've been following a couple of tutorials to get started. I've been searching for specifically how to include a date picker in the add new custom post type. </p>
<p><a href="https://i.stack.imgur.com/sCISj.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/sCISj.png" alt="My Events Custom Post Type"></a></p>
<p>I want to add an extra field in here for the user to select a date to specify when the event will take place. I don't want the user to manually type out the date through text but want to use a date picker, whether it be a normal html5 datepicker or a jquery one.</p>
<p>The code i used to generate this is within the functions.php, I understand that this is probably not the best place to put all my code but i'm currently just experimenting for now but can't seem to find a solution to my problem.</p>
<pre><code> /*

function awesome_custom_post_type ()
{
$labels = array(

| I'm fairly new to wordpress and the content management system. I've been following a couple of tutorials to get started. I've been searching for specifically how to include a date picker in the add new custom post type.
[](https://i.stack.imgur.com/sCISj.png)
I want to add an extra field in here for the user to select a date to specify when the event will take place. I don't want the user to manually type out the date through text but want to use a date picker, whether it be a normal html5 datepicker or a jquery one.
The code i used to generate this is within the functions.php, I understand that this is probably not the best place to put all my code but i'm currently just experimenting for now but can't seem to find a solution to my problem.
```
/*
Custom post types
*/
function awesome_custom_post_type ()
{
$labels = array(
'name' => 'Events',
'singular_name' => 'Event',
'add_new' => 'Add Event',
'all_items' => 'All Events',
'add_new_item' => 'Add Event',
'edit_item' => 'Edit Event',
'new_item' => 'New Event',
'view_item' => 'View Event',
'search_item_label' => 'Search Events',
'not_found' => 'No Events Found',
'not_found_in_trash' => 'No Events Found in Trash',
'parent_item_colon' => 'Parent Event'
);
$args = array(
'labels' => $labels,
'public' => true,
'has_archive' => true,
'publicly_queryable' => false,
'query_var' => true,
'rewrite' => true,
'capability_type' => 'post',
'hierarchical' => true,
'supports' => array(
'title',
'editor',
'thumbnail',
),
'menu_icon' => 'dashicons-calendar-alt',
'menu_position' => 5,
'excluse_from_search' => true
);
register_post_type( 'awesome_events', $args );
}
add_action( 'init', 'awesome_custom_post_type' );
```
Thanks in advance. | With the help of sunil's answer I figured out exactly what I needed to do.
I went and downloaded the free version of Metabox at <https://wordpress.org/plugins/meta-box/>
Once I downloaded it, I've placed it in `child-theme/external/meta-box`and referenced it from `child-theme/inc/events-custom-post-type.php`.
`events-custom-post-type.php` looks like this.
```
require_once(get_stylesheet_directory() . '/external/meta-box/meta-box.php');
function custom_events ()
{
$labels = array(
'name' => 'Events',
'singular_name' => 'Event',
'add_new' => 'Add Event',
'all_items' => 'All Events',
'add_new_item' => 'Add Event',
'edit_item' => 'Edit Event',
'new_item' => 'New Event',
'view_item' => 'View Event',
'search_item_label' => 'Search Events',
'not_found' => 'No Events Found',
'not_found_in_trash' => 'No Events Found in Trash',
'parent_item_colon' => 'Parent Event'
);
$args = array(
'labels' => $labels,
'public' => true,
'has_archive' => true,
'publicly_queryable' => false,
'query_var' => true,
'rewrite' => true,
'capability_type' => 'post',
'hierarchical' => true,
'supports' => array(
'title',
'editor',
),
'menu_icon' => 'dashicons-calendar-alt',
'menu_position' => 5,
'exclude_from_search' => true
);
register_post_type( 'custom_events_post_type', $args );
}
function prefix_register_meta_boxes_events( $meta_boxes ) {
$prefix = 'custom_event_';
$meta_boxes[] = array(
'id' => $prefix . 'details',
'title' => 'Event details',
'post_types' => 'custom_events_post_type',
'context' => 'normal',
'priority' => 'high',
'fields' => array(
array(
'name' => 'Event date',
'desc' => 'Select event date',
'id' => $prefix . 'date',
'type' => 'date',
),
array (
'name' => 'Event location',
'desc' => 'Location of the event',
'id' => $prefix . 'location',
'type' => 'text'
)
)
);
return $meta_boxes;
}
add_action( 'init', 'custom_events' );
add_filter( 'rwmb_meta_boxes', 'prefix_register_meta_boxes_events' );
```
The `custom_events` function sets up the custom post type while the `prefix_register_meta_boxes_events` function sets up the custom field date picker.
You just have to make sure that in `prefix_register_meta_boxes_events` function, where it says `post_types` to add what your own custom post type is registered as.
After that, I just referenced this file in `child-theme/functions.php` like so.
```
require get_stylesheet_directory() . '/inc/events-custom-post-type.php';

Tested. |
308,509 | <p>In the <code>register_post_status</code>, I've already disabled
<code>show_in_admin_all_list</code> & <code>show_in_admin_status_list</code> for my custom status <code>my_hidden_status</code></p>
<p>However, from the query log the post_status <code>my_hidden_status</code> is still not being filtered out (when loading edit.php)</p>
<p>e.g.</p>
<pre><code>SELECT post_status, COUNT( * ) AS num_posts FROM st_posts WHERE
post_type = 'my_cpt' GROUP BY post_status;
</code></pre>
<p>The post_status I wanted to filter is actually over 90% of my CPT, so
if the query is rewritten as</p>
<pre><code>SELECT post_status, COUNT( * ) AS num_posts FROM st_posts WHERE
post_type = 'my_cpt' AND post_status != 'my_hidden_status' GROUP BY
post_status;
</code></pre>
<p>It can greatly improve performance.</p>
<p>Is this a bug?</p>

It counts all posts by status so that it has these numbers handy if the page needs them later.</p>\n\n<p>My hunch is that the query was kept simple on purpose to prevent the possibility of multiple little-used post statuses clogging and slowing down the query. For example, testing on phpMyAdmin, the base query took 0.0011 seconds with around 300 posts. Adding clauses to filter out 5 unused or little-used post statuses raised the time to 0.0024.</p>\n\n<p>In your situation, you're correct that filtering out 90% of potential results would speed up the query. You could try filtering it with the <a href=\"https://developer.wordpress.org/reference/hooks/query/\" rel=\"nofollow noreferrer\">query filter</a>.</p>\n\n<p>As a side note: while researching this I noticed that if <code>\"public\" => true</code> in <code>register_post_status</code>, it overrides the <code>show_in_admin_all_list</code> value and displays posts with that status on the edit screen. I'd call that part a bug, since in other <code>register_*</code> functions the more specific args tend to override the <code>public</code> arg.</p>\n"

If you check WordPress <a href=\"https://codex.wordpress.org/Function_Reference/register_post_status\" rel=\"nofollow noreferrer\">Codex entry for register_post_status() function</a>, you'll see it's clearly mentioned in a notice:</p>\n\n<blockquote>\n <p><strong>NOTICE:</strong></p>\n \n <p>This function does NOT add the registered post status to the admin panel. This functionality is <strong>pending future development</strong>. Please refer to <a href=\"https://core.trac.wordpress.org/ticket/12706\" rel=\"nofollow noreferrer\">Trac Ticket #12706</a> . Consider the action hook <a href=\"http://core.trac.wordpress.org/browser/tags/3.5.1/wp-admin/includes/meta-boxes.php#L183\" rel=\"nofollow noreferrer\">post_submitbox_misc_actions</a> for adding this parameter.</p>\n</blockquote>\n\n<p>Also, if you visit the <a href=\"https://core.trac.wordpress.org/ticket/12706\" rel=\"nofollow noreferrer\">Related Ticket</a>, you'll see that the discussion to implement it fully is going on for over 8 years now (starting from March 2010)! However, since WordPress is open source community driven software & there weren't a lot of volunteers willing to work on this feature, it's still pending proper implementation.</p>\n\n<p>The <a href=\"https://core.trac.wordpress.org/ticket/12706\" rel=\"nofollow noreferrer\">Trac Ticket #12706</a> states the following in the description:</p>\n\n<blockquote>\n <p>A developer should be able to register a custom post status using <strong>register_post_status()</strong>. The admin UI (including post submit box and quick edit) <strong>should reflect this new custom post status</strong>. Furthermore, there are many hard-coded references to 'draft' and 'pending' statuses in core that should properly use the post status API.</p>\n \n <p><strong>All existing arguments to register_post_status() should be fully implemented</strong>, should also support per-post-type arguments. As things get implemented across core, there will likely be a need for supporting capabilities and bits of API.</p>\n</blockquote>\n\n<p>Now if you look at the WordPress core CODE, you'll see that this description is still valid. That means:</p>\n\n<ul>\n<li><p>The admin UI (including post submit box and quick edit) <strong>doesn't reflect custom post status</strong>. Check <a href=\"https://github.com/WordPress/WordPress/blob/cd4c960a6c17e683bcc76f1efaadcb272955bb83/wp-admin/includes/meta-boxes.php#L91-L113\" rel=\"nofollow noreferrer\">this part of the CODE</a> in core:</p>\n\n<pre><code><?php _e( 'Status:' ); ?> <span id=\"post-status-display\">\n<?php\n switch ( $post->post_status ) {\n case 'private':\n _e( 'Privately Published' );\n break;\n case 'publish':\n _e( 'Published' );\n break;\n case 'future':\n _e( 'Scheduled' );\n break;\n case 'pending':\n _e( 'Pending Review' );\n break;\n case 'draft':\n case 'auto-draft':\n _e( 'Draft' );\n break;\n }\n?>\n</span>\n</code></pre>\n\n<p>The CODE contains <strong>no action / filter hook for any custom post status</strong> or for any modification whatsoever. So the only logical way at the moment is to use some JavaScript to alter the UI implementation until this feature is implemented in WordPress core. </p></li>\n<li><p>All existing arguments to <strong><em>register_post_status()</em> is not yet fully implemented</strong> & hence may look buggy.</p></li>\n<li><p>And a lot more discussion & work is needed for the full implementation of the Post Status API.</p></li>\n</ul>\n\n<h2>What to do about this Lack of Feature or Bug?</h2>\n\n<p>Call it a lack of feature or call it a bug, the fact remains: there's a lot more work that needs to be done to complete the Post Status API. \nSo if this is too important for you, it's better to join in the discussion in the Support Ticket mentioned above to expedite the development process.</p>\n\n<p>Although the entire development process will need a lot of voluntary work, you can still comment on it about the argument <code>show_in_admin_all_list</code> not affecting the query, so that at least this part of the anomaly can be improved earlier than the rest of the Status API.</p>\n\n<h2>What to do until core doesn't implement the features properly?</h2>\n\n<p>As it is now, <code>show_in_admin_all_list</code> argument only affects the <code>All(*)</code> status header part of the All Posts Listing, for example:</p>\n\n<p><a href=\"https://i.stack.imgur.com/VqQXA.png\" rel=\"nofollow noreferrer\"><img src=\"https://i.stack.imgur.com/VqQXA.png\" alt=\"All Posts Listing Status Header (All Posts Selected)\"></a>\n<br><sub><strong>Image-1:</strong> All Posts Listing Status Header (All Posts Selected)</sub></p>\n\n<p>However, it doesn't affect the posts that appear in the list (although it should).</p>\n\n<p>To make sure that posts with your custom status <code>my_hidden_status</code> doesn't appear in the list as well, you need to set the <code>public</code> argument to <code>false</code>.</p>\n\n<p>This will make the <code>register_post_status()</code> function call look like the following:</p>\n\n<pre><code>register_post_status( 'my_hidden_status', array(\n 'label' => _x( 'My Hidden Status', 'post' ),\n 'public' => false,\n 'show_in_admin_all_list' => false, \n 'show_in_admin_status_list' => false,\n 'label_count' => _n_noop( 'My Hidden Status <span class=\"count\">(%s)</span>', 'My Hidden Status <span class=\"count\">(%s)</span>' )\n) );\n</code></pre>\n\n<p>This will show the correct count in <code>All(*)</code> status header and also remove the posts with <code>my_hidden_status</code> from the <code>All Posts</code> or <code>All {custom_post_type}</code> listing.</p>\n\n<p>Of course, this will essentially make posts with <code>my_hidden_status</code> inaccessible from WordPress Admin Panel.

| In the `register_post_status`, I've already disabled
`show_in_admin_all_list` & `show_in_admin_status_list` for my custom status `my_hidden_status`
However, from the query log the post\_status `my_hidden_status` is still not being filtered out (when loading edit.php)
e.g.
```
SELECT post_status, COUNT( * ) AS num_posts FROM st_posts WHERE
post_type = 'my_cpt' GROUP BY post_status;
```
The post\_status I wanted to filter is actually over 90% of my CPT, so
if the query is rewritten as
```
SELECT post_status, COUNT( * ) AS num_posts FROM st_posts WHERE
post_type = 'my_cpt' AND post_status != 'my_hidden_status' GROUP BY
post_status;
```
It can greatly improve performance.
Is this a bug? | >
> ***TL;DR:*** It's not a bug (*as we generally understand it*), rather it's a feature that was **never fully implemented** in WordPress.
>
>
>
---
Status of `register_post_status()`
----------------------------------
`register_post_status()` function was never fully implemented in WordPress. If you check WordPress [Codex entry for register\_post\_status() function](https://codex.wordpress.org/Function_Reference/register_post_status), you'll see it's clearly mentioned in a notice:
>
> **NOTICE:**
>
>
> This function does NOT add the registered post status to the admin panel. This functionality is **pending future development**. Please refer to [Trac Ticket #12706](https://core.trac.wordpress.org/ticket/12706) . Consider the action hook [post\_submitbox\_misc\_actions](http://core.trac.wordpress.org/browser/tags/3.5.1/wp-admin/includes/meta-boxes.php#L183) for adding this parameter.
>
>
>
Also, if you visit the [Related Ticket](https://core.trac.wordpress.org/ticket/12706), you'll see that the discussion to implement it fully is going on for over 8 years now (starting from March 2010)! However, since WordPress is open source community driven software & there weren't a lot of volunteers willing to work on this feature, it's still pending proper implementation.
The [Trac Ticket #12706](https://core.trac.wordpress.org/ticket/12706) states the following in the description:
>
> A developer should be able to register a custom post status using **register\_post\_status()**. The admin UI (including post submit box and quick edit) **should reflect this new custom post status**. Furthermore, there are many hard-coded references to 'draft' and 'pending' statuses in core that should properly use the post status API.
>
>
> **All existing arguments to register\_post\_status() should be fully implemented**, should also support per-post-type arguments. As things get implemented across core, there will likely be a need for supporting capabilities and bits of API.
>
>
>
Now if you look at the WordPress core CODE, you'll see that this description is still valid. That means:
* The admin UI (including post submit box and quick edit) **doesn't reflect custom post status**. Check [this part of the CODE](https://github.com/WordPress/WordPress/blob/cd4c960a6c17e683bcc76f1efaadcb272955bb83/wp-admin/includes/meta-boxes.php#L91-L113) in core:
```
<?php _e( 'Status:' ); ?> <span id="post-status-display">
<?php
switch ( $post->post_status ) {
case 'private':
_e( 'Privately Published' );
break;
case 'publish':
_e( 'Published' );
break;
case 'future':
_e( 'Scheduled' );
break;
case 'pending':
_e( 'Pending Review' );
break;
case 'draft':
case 'auto-draft':
_e( 'Draft' );
break;
}
?>
</span>
```
The CODE contains **no action / filter hook for any custom post status** or for any modification whatsoever. So the only logical way at the moment is to use some JavaScript to alter the UI implementation until this feature is implemented in WordPress core.
* All existing arguments to ***register\_post\_status()* is not yet fully implemented** & hence may look buggy.
* And a lot more discussion & work is needed for the full implementation of the Post Status API.
What to do about this Lack of Feature or Bug?
---------------------------------------------
Call it a lack of feature or call it a bug, the fact remains: there's a lot more work that needs to be done to complete the Post Status API.
So if this is too important for you, it's better to join in the discussion in the Support Ticket mentioned above to expedite the development process.
Although the entire development process will need a lot of voluntary work, you can still comment on it about the argument `show_in_admin_all_list` not affecting the query, so that at least this part of the anomaly can be improved earlier than the rest of the Status API.
What to do until core doesn't implement the features properly?
--------------------------------------------------------------
As it is now, `show_in_admin_all_list` argument only affects the `All(*)` status header part of the All Posts Listing, for example:
[](https://i.stack.imgur.com/VqQXA.png)
**Image-1:** All Posts Listing Status Header (All Posts Selected)
However, it doesn't affect the posts that appear in the list (although it should).
To make sure that posts with your custom status `my_hidden_status` doesn't appear in the list as well, you need to set the `public` argument to `false`.
This will make the `register_post_status()` function call look like the following:
```
register_post_status( 'my_hidden_status', array(
'label' => _x( 'My Hidden Status', 'post' ),
'public' => false,
'show_in_admin_all_list' => false,
'show_in_admin_status_list' => false,
'label_count' => _n_noop( 'My Hidden Status <span class="count">(%s)</span>', 'My Hidden Status <span class="count">(%s)</span>' )
) );
```
This will show the correct count in `All(*)` status header and also remove the posts with `my_hidden_status` from the `All Posts` or `All {custom_post_type}` listing.
Of course, this will essentially make posts with `my_hidden_status` inaccessible from WordPress Admin Panel. If that was the intent, then fine, otherwise, you may use the `show_in_admin_status_list` to show the posts with `my_hidden_status` in a separate listing header:
```
register_post_status( 'my_hidden_status', array(
'label' => _x( 'My Hidden Status', 'post' ),
'public' => false,
'show_in_admin_all_list' => false,
'show_in_admin_status_list' => true,
'label_count' => _n_noop( 'My Hidden Status <span class="count">(%s)</span>', 'My Hidden Status <span class="count">(%s)</span>' )
) );
```
This will show the Post Lists with the status `my_hidden_status` in a separate header like the following:
[](https://i.stack.imgur.com/EF0wV.png)
**Image-2:** All Posts Listing Status Header (Custom Status Selected)
DB Query Optimization Issue:
----------------------------
The related DB Query comes from `wp_count_posts()` function in `wp-includes/post.php` file. If you take a look at the [related CODE](https://github.com/WordPress/WordPress/blob/c9dce0606b0d7e6f494d4abe7b193ac046a322cd/wp-includes/post.php#L2457-L2467), you'll see that the arguments from `register_post_status()` function are not implemented there. Also, there's no way to filter or extend this part of the core CODE either:
```
$query = "SELECT post_status, COUNT( * ) AS num_posts FROM {$wpdb->posts} WHERE post_type = %s";
if ( 'readable' == $perm && is_user_logged_in() ) {
$post_type_object = get_post_type_object( $type );
if ( ! current_user_can( $post_type_object->cap->read_private_posts ) ) {
$query .= $wpdb->prepare(
" AND (post_status != 'private' OR ( post_author = %d AND post_status = 'private' ))",
get_current_user_id()
);
}
}
$query .= ' GROUP BY post_status';
```
Unless both `show_in_admin_all_list` and `show_in_admin_status_list` are set to `false` for a particular status, related posts shouldn't be removed from the query anyway. Otherwise WordPress will not be able to generate the proper `status header` (as shown in image-2).
However, in the case where both `show_in_admin_all_list` and `show_in_admin_status_list` are set to `false`, WordPress doesn't need the count information for that custom status. So logically in this case you'll have a little query performance improvement with `AND post_status != 'my_hidden_status'` part, if you have a large number of posts (like Millions) and most of your posts (as you said 90%) are from that custom status.
Still, there are two reasons why core may not update this part of the CODE even though there may be a little performance gain in your particular case:
1. **WordPress Database uses an index named `type_status_date`** that indexes `wp-posts` table entries based on `post_type`, `post_status`, `post_date` and `ID` fields. **So queries are fast enough even without the `AND post_status != 'my_hidden_status'` part**.
I've tested with 15K+ posts and it only takes a few milliseconds. Check [this MySQL Document](https://dev.mysql.com/doc/refman/8.0/en/group-by-optimization.html) for more information on GROUP BY Optimization with index. With some tweaks to MySQL index, you may even get better results without even changing WP Core. For example, adding another index with `post_type` and `post_status` column may give you a few milliseconds gain.
2. Even though adding `AND post_status != 'my_hidden_status'` may make the query faster (merely by milliseconds) in your particular case, WordPress still may not update it, because WordPress will have to **consider the possibility where a hidden custom status has only a few posts**. In those cases, adding `AND post_status != 'my_hidden_status'` will actually make the query results a bit slower (only by a few milliseconds).
So considering everything, WordPress may or may not update the query with `AND post_status != 'my_hidden_status'` when both `show_in_admin_all_list` and `show_in_admin_status_list` are set to `false` for a custom status. However, in my opinion, at least making the related query filterable will improve the flexibility for the developers. |

What you want is `wp_update_post`, you're also using `WP_Query` incorrectly:
```
$notpayed\_posts = new WP\_Query( array(
'meta\_key' => '\_payment',
'meta\_value' => '0'
) );
```
while ($notpayed_posts->have_posts()) {
$notpayed_posts->the_post();
wp_update_post( array(
'ID' => get_the_ID(),
'post_status' => 'draft'
));
}
wp_reset_postdata();
```
Also, keep in mind that your query is an expensive/very slow post meta query, post meta isn't built for searching or queries where you're looking for posts. Consider a taxonomy term.
You also do nothing to change the meta afterwards, so if there are 10 posts that match, then every page load will try to update 10 posts, even if they've already been updated! Either change the meta value with `update_post_meta` or check the post status in the query, e.g.
```
$notpayed_posts = new WP_Query( array(
'post_status' => 'publish',
'meta_key' => '_payment',
'meta_value' => '0'
) );
```
Additionally, use a cron job, don't do it on every page load by using the `init` hook, it's very bad for performance and incompatible with page caching |

| I am using `save_post` for a function to send an email when a post is updated by a user. This is firing twice and I am aware this is due to the post revisions and autosaves.
I have tried to prevent this from happening by wrapping my `wp_mail` within a conditional statement but this still fires twice. What adjustments do I need to make to ensure this only fires once when a user updates the post?
```
function updated_search_notification($post_id)
{
$post_type = get_post_type($post_id);
if ($post_type === 'utility-search') {
if ((wp_is_post_revision($post_id)) || (wp_is_post_autosave($post_id))) {
// post is autosave
} else {
// Message Variables
$siteurl = get_option('siteurl');
$post_url = '' . $siteurl . '/wp-admin/post.php?post=' . $post_id . '&action=edit';
$new_search_name = '';
//$new_search_email = get_option( 'new_search_email' );
$new_search_email = '[email]';
$utility_search_customer = '';
$subject = 'Your search has been updated';
// Message Contents
$message = "[Message Contents]";
// Send Email
wp_mail($new_search_email, $subject, $message);
}
}
}
add_action('save_post', 'updated_search_notification', 10, 3);
``` | First, you can use this hook to target only one custom type:
<https://developer.wordpress.org/reference/hooks/save_post_post-post_type/>
This hook (and `save_post`) is called the first time when you click on "new ..." and then the hook is called with `$update = FALSE`.
Then to send e-mail only when the object is updated, you can test `$update` like this:
```
const UTILITY_SEARCH_POST_TYPE = "utility-search";
add_action("save_post_" . UTILITY_SEARCH_POST_TYPE, function ($post_ID, $post, $update) {
if (wp_is_post_autosave($post_ID)) {
return;
}
if (!$update) { // if new object
return;
}
// preparing e-mail
...
// sending e-mail
wp_mail(...);
}, 10, 3);

Needs to be:
```
<i class="<?php the_field('course_feature_icon'); ?>"></i>
```
That's all that's wrong with your code. It should then work assuming:
1. You have a custom field, `course_feature_icon`, whose value is a valid CSS class.
2. You have the necessary CSS to add an icon based on that class.
One last suggestion though. For safety you should [escape](https://developer.wordpress.org/themes/theme-security/data-sanitization-escaping/) the field value before outputting it as a class:
```
<i class="<?php echo esc_attr( get_field('course_feature_icon') ); ?>"></i>

(The menu-item is actually `post-type`, so there should be some `register_post_type` command i think). | WooCommerce styles the icon via this CSS file: `woocommerce/assets/css/menu.css`, and here's the corresponding code (*pretty-printed* or actually, I copied it from [`woocommerce/assets/css/menu.scss`](https://plugins.trac.wordpress.org/browser/woocommerce/tags/3.4.3/assets/css/menu.scss#L17)):
```
#adminmenu #toplevel_page_woocommerce .menu-icon-generic div.wp-menu-image::before {

So you can change the `font-family` and the `content` (and other) properties to suit your custom icon.

| My parent theme calls a function:
```
function get_nav_markup() {
ob_start();
?>
<nav class="navbar navbar-toggleable-md navbar-inverse site-navbar" role="navigation">
<div class="container">
<?php if ( is_home() ): ?>
<h1 class="navbar-brand mb-0">
<?php echo get_sitename_formatted(); ?>
</h1>
<?php else: ?>
<a href="<?php echo bloginfo( 'url' ); ?>" class="navbar-brand">
<?php echo get_sitename_formatted(); ?>
</a>
<?php endif; ?>
<button class="navbar-toggler collapsed" type="button" data-toggle="collapse" data-target="#header-menu" aria-controls="header-menu" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<?php
wp_nav_menu( array(
'theme_location' => 'header-menu',
'depth' => 2,
'container' => 'div',
'container_class' => 'collapse navbar-collapse',
'container_id' => 'header-menu',
'menu_class' => 'nav navbar-nav ml-md-auto',
) );
?>
</div>
</nav>
<?php
return ob_get_clean();
}
```
and then later uses it like so:
```
function get_header_markup() {
global $post;
echo get_nav_markup( $post );
$videos = get_header_videos( $post );
$images = get_header_images( $post );
if ( $videos || $images ) {
echo get_header_media_markup( $post, $videos, $images );
}
else {
echo get_header_default_markup( $post );
}
}
```
Is there anyway that I can overwrite get\_nav\_markup or at least append additional information immediately after it in my child theme?
Given the way the parent theme function written I don't think I can. But I really need to be able to add some additional DIVs and PHP right after the /nav | Ok so here is what I have decided given the situation.
1. I have copied the header.php file into my child theme.
2. I have changed the line in the header file from get\_header\_markup(); to get\_header\_markup\_updated();
3. I have then created a new function in my child themes function.php file called get\_header\_markup\_updated.
4. I started the function off my copying the existing one from the parent theme, but then added the code I needed... where I needed it.
The result now looks like:
```
function get_header_markup_updated() {
global $post;
echo get_nav_markup( $post ); ?>
<div class="breadcrumbnav">
<!-- Inserted all my other code here -->
</div>
<?php
$videos = get_header_videos( $post );
$images = get_header_images( $post );
if ( $videos || $images ) {
echo get_header_media_markup( $post, $videos, $images );
}
else {
echo get_header_default_markup( $post );
}
}
?>
```
This seems to be working just fine. Hopefully this will also be the least obtrusive going forward. |

308,854 | <p>To start I've been searching through several questions and documentation pieces but it seems with WordPress' <code>v2</code> many of the old questions are no longer valid. What I am trying to do is get all posts or a singular post from a category in Postman instead of the common returned 10 posts without having to modify the API in functions.php.</p>
<h2>tldr</h2>
<p>I started with referencing the <a href="https://developer.wordpress.org/rest-api/" rel="noreferrer">REST API Handbook</a> and reviewing the <a href="https://developer.wordpress.org/rest-api/reference/posts/#schema" rel="noreferrer">schema</a> I saw <code>categories</code> and I can return the 10 latest categories using:</p>
<pre><code>http://foobar.com/wp-json/wp/v2/posts/categories_name=hello
</code></pre>
<p>referencing the <a href="https://developer.wordpress.org/rest-api/reference/posts/#arguments" rel="noreferrer">arguments</a> I see <code>per_page</code> so I tried:</p>
<pre><code>http://foobar.com/wp-json/wp/v2/posts/categories_name=hello?per_page=1
</code></pre>
<p>and it returns 10 posts from the category <code>hello</code> so I modified and tried:</p>
<pre><code>http://foobar.com/wp-json/wp/v2/posts/categories_name=hello&per_page=1
</code></pre>
<p>and I get an error returned:</p>

<pre><code>http://foobar.com/wp-json/wp/v2/posts/?per_page=1

<p>and I get a singular post so I modified my attempt to:</p>
<pre><code>http://foobar.com/wp-json/wp/v2/posts/?per_page=1$categories_name=hello

<p>It ignores the category type and returns the latest post. Reading <a href="https://wordpress.stackexchange.com/questions/274890/get-more-than-10-posts-in-a-specific-category-with-the-wordpress-api">Get more than 10 posts in a specific category with the WordPress API</a> I pulled the ID of a category (4) after using:</p>

<pre><code>http://foobar.com/wp-json/wp/v2/posts/?categories=4&per_page=1

<p>and I get:</p>

| To start I've been searching through several questions and documentation pieces but it seems with WordPress' `v2` many of the old questions are no longer valid. What I am trying to do is get all posts or a singular post from a category in Postman instead of the common returned 10 posts without having to modify the API in functions.php.
tldr
----
I started with referencing the [REST API Handbook](https://developer.wordpress.org/rest-api/) and reviewing the [schema](https://developer.wordpress.org/rest-api/reference/posts/#schema) I saw `categories` and I can return the 10 latest categories using:
```
http://foobar.com/wp-json/wp/v2/posts/categories_name=hello
```
referencing the [arguments](https://developer.wordpress.org/rest-api/reference/posts/#arguments) I see `per_page` so I tried:
```
http://foobar.com/wp-json/wp/v2/posts/categories_name=hello?per_page=1
```
and it returns 10 posts from the category `hello` so I modified and tried:
```
http://foobar.com/wp-json/wp/v2/posts/categories_name=hello&per_page=1
```
and I get an error returned:
>
> {
> "code": "rest\_invalid\_param",
> "message": "Invalid parameter(s): per\_page",
> "data": {
> "status": 400,
> "params": {
> "per\_page": "per\_page is not of type integer."
> }
> } }
>
>
>
Searching through Google I [see How to retrieve a list of categories/ tag in Wordpress REST API](https://stackoverflow.com/questions/20158417/how-to-retrieve-a-list-of-categories-tag-in-wordpress-rest-api) but the answers are based on `v1`.
Trying [Wordpress API JSON return limit](https://stackoverflow.com/questions/29171854/wordpress-api-json-return-limit) I use:
```
http://foobar.com/wp-json/wp/v2/posts/?per_page=1
```
and I get a singular post so I modified my attempt to:
```
http://foobar.com/wp-json/wp/v2/posts/?per_page=1$categories_name=hello
```
It ignores the category type and returns the latest post. Reading [Get more than 10 posts in a specific category with the WordPress API](https://wordpress.stackexchange.com/questions/274890/get-more-than-10-posts-in-a-specific-category-with-the-wordpress-api) I pulled the ID of a category (4) after using:
```
http://foobar.com/wp-json/wp/v2/categories
```
then coded:
```
http://foobar.com/wp-json/wp/v2/posts/?categories=4&per_page=1
```
and I get:
>
> {
> "code": "rest\_invalid\_param",
> "message": "Invalid parameter(s): per\_page",
> "data": {
> "status": 400,

I thought I might be able to use `-1` similar to the development of a theme but I get an error.

After reviewing the documentation on [Pagination](https://developer.wordpress.org/rest-api/using-the-rest-api/pagination/#pagination-parameters) it seems to only work with the `post` and not any `category`. I can only get more than 10 posts if I use `/wp-json/wp/v2/posts?per_page=20`, too.
Question
--------
When calling a site's WP API how can I control the `per_page` return of a category wether it be 1 post or all posts? | After a few hours trying different permutations of how to get a return on categories I found my answer. To establish the listing of categories associated with `post` use:
```
/wp-json/wp/v2/categories/
```
I needed a particular category and the `id` of that category was `4` and the slug was called `foobar`.
To get 1 post associated with the category `foobar` I had to use:
```
/wp-json/wp/v2/posts?categories=4&per_page=1
```
To get 100 posts associated with the category `foobar` I used:
```
/wp-json/wp/v2/posts?categories=4&per_page=100
```
and as I found out and it was also mentioned in the [answer](https://wordpress.stackexchange.com/a/308869/25271) my logic of using `-1` was incorrect, you can only use 1 to 100. As it was discussed in the comment on what to do if there are more than 100 posts, well you can call the page using `offset` and I found that under the documentation [Pagination](https://developer.wordpress.org/rest-api/using-the-rest-api/pagination/#pagination-parameters):
```
/wp-json/wp/v2/posts?categories=4&offset=10&per_page=1
```
so to get more than 100 you'd to build a loop in whatever language you wanted and push it to a file. To assist with the looping under `/wp-json/wp/v2/categories/` and when you reference the category you can reference the total count under `count` which is below the `id`. |

Here is a screenshot of the inspection:
[](https://i.stack.imgur.com/gbwB0.png)
Any ideas how I can block this request? | The Youtube is called by a script named "jquery.st.youtube.js" which is located in your themes folder. You seem to use a premium theme named "Wunder" which effectively means you can do one of two things:
1) You can edit the themes files directly, search for the enqueuing of the script jquery.st.youtube.js (most likely within the functions.php of the theme, but maybe somewhere else) and remove the line/turn the line into a comment. CAUTION: Do not do this if you plan to install updates to this theme. Whenever you update your theme, the changes you made are gone, so i would advise against this way. However, if the support cycle is over, you don't plan to update the theme and need a quick dirty fix RITE NAO, it is a possibility.
2) You create a child theme (<https://codex.wordpress.org/Child_Themes>) of your premium theme. After that, find the handle which is used for enqueueing the "jquery.st.youtube.js"-Script. In the functions.php of your child-theme, you hook into the wp\_enqueue\_scripts action with a big priority like 1000 and use wp\_dequeue\_script to remove it from the action.
Example:
The function in your premium theme where the scripts are enqueued MAY look like this:
```
add_action( 'wp_enqueue_scripts', 'wunder_enqueue_scripts' );
function wunder_enqueue_scripts(){
wp_enqueue_script('wunder-youtube',"jquery.st.youtube.js",array('jquery'),"",true);
..... (more scripts)
}
```
In your child-themes functions.php, you can now insert a function to dequeue the script like this:
```
add_action( 'wp_enqueue_scripts', 'remove_that_darn_youtube_scripts',1000 );
function remove_that_darn_youtube_scripts(){
wp_dequeue_script('wunder-youtube');
}
```
If you don't understand what any of these functions do, then you can read up on [wp\_enqueue\_script](https://developer.wordpress.org/reference/functions/wp_enqueue_script/) and [wp\_dequeue\_script](https://codex.wordpress.org/Function_Reference/wp_dequeue_script) in the wordpress codex (or you get someone to code for you ;) )
While this is way more effort, i would suggest that you take route 2, as it is the "correct" way to do these things. Of Course, after you have built that child theme, you have to activate it for the changes to work.
Last but not least: DON'T DO THIS ON LIVE! Get yourself a backup of the site, and do the changes on local/a subsite/some other webspace and TEST IT before you put it on the live site! |

but the post\_content 's values ist null any suggestion? thanks | Do you load own javascripts into the admin? If i recall correctly, if SCRIPT\_DEBUG is set to true, the javascripts are not concenated, but loaded seperately. So if a custom javascript doesn't play well being concenated, this can lead to the whole concenated javascript being corrupt and not being run correctly.
Try removing the added javascripts one by one and check if that changes anything. |
308,941 | <p>In August, GDPR requires all websites to have a cookie notification on every page. I am creating a custom post type plugin - but I'm having one problem.

| I have a question about [this](https://codex.wordpress.org/Post_Types#Custom_Post_Types) documentation.
Why would I register a Custom Post Type in the init function as the docs suggest? Is this only if I am not using a plugin?
As I understand it, [init runs every-time WordPress runs/is-loaded](https://codex.wordpress.org/Plugin_API/Action_Reference/init) by the user. Doesn't this mean the site is needlessly re-registering a new post type on every visit? Why not (if building a plugin) register the post type in `require_once plugin_dir_path( __FILE__ )` just when the plugin activates?
Wouldn't that also speed up the site? Or am I interpreting `init()` wrong? Surely the custom post type persists in the database somewhere so doesn't have to be called on every `init()`?
Here is the Custom Post Type example from the docs, using `init()`:
```
function create_post_type() {
register_post_type( 'acme_product',
array(
'labels' => array(
'name' => __( 'Products' ),
'singular_name' => __( 'Product' )
),
'public' => true,
'has_archive' => true,
)
);
}
add_action( 'init', 'create_post_type' );
``` | `register_post_type` function should be executed every time a WP request is made. Default post types don't have this requirement. You can use your code as is, in MU plugin. Just create a `.PHP` file with this code, and place it in `mu-plugins` sub-folder of `wp-content`. You don't need to provide any standard plugin headers. |

<p>But to in WordPress, I have used WP_Bootstrap_Navwalker() for the navigation menu. I have put depth => 3 but it's not showing multi level menu as expected. Here is my code: </p>
<pre><code><?php
wp_nav_menu( array(
'theme_location' => 'primary',
'depth' => 3,
'container' => 'div',
'container_class' => 'collapse navbar-collapse',
'container_id' => 'mainNavbar',
'menu_class' => 'navbar-nav',
'fallback_cb' => 'WP_Bootstrap_Navwalker::fallback',
'walker' => new WP_Bootstrap_Navwalker()
) );
?>
</code></pre>
<p>But it's just working for dropdown only. It's not showing submenu of submenu. How can I fix this problem? </p>

And it's working fine for me:
[](https://i.stack.imgur.com/UCVhR.jpg)
But to in WordPress, I have used WP\_Bootstrap\_Navwalker() for the navigation menu. I have put depth => 3 but it's not showing multi level menu as expected. Here is my code:
```
<?php
wp_nav_menu( array(
'theme_location' => 'primary',
'depth' => 3,
'container' => 'div',
'container_class' => 'collapse navbar-collapse',
'container_id' => 'mainNavbar',
'menu_class' => 'navbar-nav',
'fallback_cb' => 'WP_Bootstrap_Navwalker::fallback',
'walker' => new WP_Bootstrap_Navwalker()
) );
?>
```
But it's just working for dropdown only. It's not showing submenu of submenu. How can I fix this problem?
[](https://i.stack.imgur.com/ZuNdV.jpg) | Here some thing interesting for you
**STEP 1**
add a script to header like below ( it's always better go for the enqueue method . i need some one to help me with properly adding the below script in WordPress way .jquery should run before the second script>
```
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript"></script>
<script>
$(document).ready(function () {
$('.dropdown-menu a.dropdown-toggle').on('click', function(e) {
if (!$(this).next().hasClass('show')) {
$(this).parents('.dropdown-menu').first().find('.show').removeClass("show");
}
var $subMenu = $(this).next(".dropdown-menu");
$subMenu.toggleClass('show');
$(this).parents('li.nav-item.dropdown.show').on('hidden.bs.dropdown', function(e) {
$('.dropdown-submenu .show').removeClass("show");
});
return false;
});
});
</script>
```
**STEP 2**
Add the css like below :
```
.dropdown-submenu {
position: relative;
}
.dropdown-submenu a::after {
transform: rotate(-90deg);
position: absolute;
right: 6px;
top: .8em;
}
.dropdown-submenu .dropdown-menu {
top: 0;
left: 100%;
margin-left: .1rem;
margin-right: .1rem;
}
/* to show the arrow */
.dropdown-submenu a::after {
transform: rotate(-90deg);
position: absolute;
right: 6px;
top: .8em;
}
.dropdown-toggle a::after{
transform: rotate(-90deg);
position: absolute;
right: 6px;
top: .8em;
}
```
**STEP 3**
Now go inside the walker class :
search for `&& 0 === $depth` and remove it. Also make sure that
`'depth' => 3`
Now it should start showing the 3rd level menu . some additional css might be required.
This is being added up in header :
```
wp_nav_menu( array(
'theme_location' => 'primary',
'depth' => 3,
'container' => 'div',
'container_class' => 'collapse navbar-collapse',
'container_id' => 'bs-example-navbar-collapse-1',
'menu_class' => 'nav navbar-nav',
'fallback_cb' => 'WP_Bootstrap_Navwalker::fallback',
'walker' => new WP_Bootstrap_Navwalker(),
) );

| I have a widget located at `/child-theme/includes/custom-widget.php`.
How do I call `register_widget` and reference that widget?
I've tried something like the following inside `functions.php`:
```
function SER_register_widgets() {
register_widget( 'includes/custom-widget.php' );
}
add_action( 'widgets_init', 'SER_register_widgets' );
```
but this does not work.
Help appreciated. | include that file in your functions.php file like
`require_once('includes/custom-widgets.php');`
then you can call `add_action()` hook, in your case
`add_action('widgets_init', 'SER_register_widgets'); .`
the idea is to make that function ( ser\_register\_widgets ) visible in current php file ( functions.php file in this case ) |

| I need to show the post featured image at the desired position on my theme template. At the same time, I need its width to be 300px and the height- adaptive.
What code should I add to my template? | You can create custom size image with [`add_image_size()`](https://developer.wordpress.org/reference/functions/add_image_size/) in the functions.php
```
function add_custom_size_images() {
// Add image size width 300 with unlimited height.
add_image_size( 'featured-image-300', 300 );
}
add_action( 'after_setup_theme', 'add_custom_size_images' );
```
And in the template to get the size that you created with [`the_post_thumbnail()`](https://developer.wordpress.org/reference/functions/the_post_thumbnail/)
```
the_post_thumbnail( 'featured-image-300' );
```
**Notice:** If you want it to work with the old images that you uploaded already you need to regenarate the thumbnails. There are some plugins for this.

For production purposes, I would separate that as a third plugin and use <a href=\"https://codex.wordpress.org/Function_Reference/is_plugin_active\" rel=\"nofollow noreferrer\">is_plugin_active()</a> function to make sure that all the dependencies are in place.</p>\n"

* fep\_save\_message (from back-end)
* fep\_action\_message\_after\_send (from front-end)
Before sending a email few things are checked, like publishig or sending status (includes/class-fep-emails.php):
```
function save_send_email( $postid, $post ) {
if ( ! $post instanceof WP_Post ) {
$post = get_post( $postid );

return;
}
$this->send_email( $postid, $post );
}
```

```
function send_sms( $postid, $post ) {
if ( ! $post instanceof WP_Post ) {
$post = get_post( $postid );
}
if ( 'publish' != $post->post_status ){
return;
}
if ( get_post_meta( $postid, '_fep_email_sent', true ) ){
return;

if( function_exists('twl_send_sms') ) {
$participants = fep_get_participants( $postid );
// check if recipients exists, for each get the phone number,
// send message and mark sms as sent (or save sms send time)
$args = array(
'message' => $post->post_title, // or $post->post_content
);
foreach ($participants as $participant) {
// get usermeta with phone number for $participant ID
$args['number_to'] = '098765';
twl_send_sms( $args );
}
}
}
add_action( 'fep_save_message', 'send_sms', 99, 2 ); //sending from back-end

309,065 | <p><strong>Background</strong></p>
<p>I am using the theme Rookie from Sportpress.</p>
<p>I created a child theme.</p>
<p>Translation files are existing, especially german in my case.</p>
<p>Wordpress is set to german language.</p>
<p><strong>The Problem</strong></p>
<p>Translation is working fine everywhere except on themes provided templates like the search results page content or pagination.</p>
<p>Affected are the SRP title, nothing found page title and nothing found page content. They just stay in default english language.
Pagination is affected too.</p>
<p>The search form in the content of a nothing found page is translated fine. I guess because it's Wordpress default template.</p>
<p><strong>Code</strong></p>
<p>here some affected code lines from the parent theme.</p>
<p>Search Title</p>
<pre><code><h1 class="page-title entry-title"><?php printf( __( 'Search Results for: %s', 'rookie' ), '<span>' . get_search_query() . '</span>' ); ?></h1>
</code></pre>
<p>Nothing Found title:</p>
<pre><code><h1 class="page-title"><?php _e( 'Nothing Found', 'rookie' ); ?></h1>
</code></pre>
<p>Nothing found text:</p>
<pre><code><p><?php _e( 'Sorry, but nothing matched your search terms. Please try again with some different keywords.', 'rookie' ); ?></p>
</code></pre>
<p>Pagination:</p>
<pre><code><?php if ( get_next_posts_link() ) : ?>
<div class="nav-previous"><?php next_posts_link( __( '<span class="meta-nav">&larr;</span> Older posts', 'rookie' ) ); ?></div>

]
| **Background**
I am using the theme Rookie from Sportpress.
I created a child theme.
Translation files are existing, especially german in my case.
Wordpress is set to german language.
**The Problem**
Translation is working fine everywhere except on themes provided templates like the search results page content or pagination.
Affected are the SRP title, nothing found page title and nothing found page content. They just stay in default english language.
Pagination is affected too.
The search form in the content of a nothing found page is translated fine. I guess because it's Wordpress default template.
**Code**
here some affected code lines from the parent theme.
Search Title
```
<h1 class="page-title entry-title"><?php printf( __( 'Search Results for: %s', 'rookie' ), '<span>' . get_search_query() . '</span>' ); ?></h1>
```
Nothing Found title:
```
<h1 class="page-title"><?php _e( 'Nothing Found', 'rookie' ); ?></h1>
```
Nothing found text:
```
<p><?php _e( 'Sorry, but nothing matched your search terms. Please try again with some different keywords.', 'rookie' ); ?></p>
```
Pagination:
```
<?php if ( get_next_posts_link() ) : ?>
<div class="nav-previous"><?php next_posts_link( __( '<span class="meta-nav">←</span> Older posts', 'rookie' ) ); ?></div>
<?php endif; ?>
<?php if ( get_previous_posts_link() ) : ?>
<div class="nav-next"><?php previous_posts_link( __( 'Newer posts <span class="meta-nav">→</span>', 'rookie' ) ); ?></div>
<?php endif; ?>
```
**Findings**
I checked that the .mo entry for german is existing with the Loco translate plugin.
I replaced the Search Result Title `Search Results for: %s` with the Category Title `Category: %s`, which gets translated on a category page (because category archive title is provided from Wordpress), but also not on the SRP!
*What could be a reason for this behaviour?*
**Workaround**
the parent theme is loading the domain via
`load_theme_textdomain( 'rookie', get_template_directory() . '/languages' );` and points to right location where all translation files (.pot, de\_DE.po and de\_DE.mo) are existing.
I copied the relevant .po and .mo files over to wp-content/languages/themes/ directory and things are working now.
*But is this the real best solution?* | I downloaded the free Rookie parent theme and have no problem displaying translations of "Search Results for: %s" on a successful search results screen.
This works in the WordPress languages folder at `wp-content/languages/themes/rookie-de_DE.mo` as well as Loco Translate's custom directory. It works there if the files are named correctly because the parent theme correctly loads the "rookie" text domain using "load\_theme\_textdomain".
Are your files named correctly under the WordPress languages directory? Unlike the de\_DE.mo file inside the theme folder, the system location requires the prefix so files should be named rookie-de\_DE.mo |

| I use the following code to change the title of WordPress **posts** and **pages**. But it changes nav menu item titles too, which I want to avoid.
I want to change the title of posts and pages in: **home page**, all **archive pages** and all **widgets** (recent posts widget, random post widget, etc.)
There are similar questions in both Stack Overflow and WP Stack Exchange suggesting to use `in_the_loop()` function. Unfortunately, it doesn't work for me, because if I place it, it also affects the sidebar widgets.
That means, if I use `in_the_loop()` function, `the_title` filter does not affect `recent posts widget`, `random post widget` etc.
So how can I apply `the_title` filter for just `post` and `page` titles, but not menu titles?
```
function pppp_title_update( $title, $id = null ) {
if ( ! is_admin() ) {
if(is_singular(array('post','page')) || is_archive() || is_home()){
if(in_the_loop()){
$current_post_id = get_the_ID();
$new_titile = get_post_meta($current_post_id, 'pp_new_title',true);
return $new_titile;
}
}
}
return $title;
}
add_filter( 'the_title', 'pppp_title_update', 10, 2 );
``` | Problem Description:
--------------------
Let me rephrase the question first. You want to:
1. Set new title to all `post` and `page` type from a meta field.
2. You want this to happen everywhere (home page, single page, widgets etc.)
3. However, you don't want this title change to happen if the title is on the Navigation Menu.
Solution:
---------
Before I give you the CODE, let me explain a few points first (based on your CODE):
How to change titles of all posts and pages:
--------------------------------------------
You already know the use of `the_title` filter. However, if you want to target all `post` and `page` type titles (but not custom post types), then your condition:
```
is_singular(array('post','page')) || is_archive() || is_home()
```
will not work. For example, it'll change custom post type on an archive page or the home page as well. This condition doesn't check if the title we are filtering is a `page` or `post` type. Instead, it checks if the page itself is either singular (`post` or `page`) or it's an archive (category, tag etc.) page or the home page. So custom post types in these pages also gets affected. Additionally, if there is a widget in a custom post type (singular) page, then by this logic, `page` or `post` titles in that widget will not be affected there.
To fix that, we need a different check, like:
```
$post = get_post( $id );
if ( $post instanceof WP_Post && ( $post->post_type == 'post' || $post->post_type == 'page' ) )
```
Why Navigation Menu title is also changed & how to stop it:
-----------------------------------------------------------
WordPress applies `the_title` filter twice on the navigation menu items' title (if the menu items correspond to existing posts or pages).
1. First as the corresponding post or page title. This happens in the `wp_setup_nav_menu_item()` function of `wp-includes/nav-menu.php` file.
2. Then as the Menu item title itself. This happens in the `Walker_Nav_Menu` class.
For your requirement, we need to stop the `the_title` filter both the times.
Fortunately, WordPress has two filters: `pre_wp_nav_menu` fires before filtering menu titles and `wp_nav_menu_items` fires after filtering menu titles. So we can use these two filters to first remove the `the_title` filter for nav menu item titles and then add the `the_title` filter back again for other titles.
CODE
----
You may use the following CODE in the theme's `functions.php` file or as a separate plugin:
```
function wpse309151_title_update( $title, $id = null ) {
if ( ! is_admin() && ! is_null( $id ) ) {
$post = get_post( $id );
if ( $post instanceof WP_Post && ( $post->post_type == 'post' || $post->post_type == 'page' ) ) {
$new_titile = get_post_meta( $id, 'pp_new_title', true );
if( ! empty( $new_titile ) ) {
return $new_titile;
}
}
}
return $title;
}
add_filter( 'the_title', 'wpse309151_title_update', 10, 2 );
function wpse309151_remove_title_filter_nav_menu( $nav_menu, $args ) {
// we are working with menu, so remove the title filter
remove_filter( 'the_title', 'wpse309151_title_update', 10, 2 );
return $nav_menu;
}
// this filter fires just before the nav menu item creation process
add_filter( 'pre_wp_nav_menu', 'wpse309151_remove_title_filter_nav_menu', 10, 2 );
function wpse309151_add_title_filter_non_menu( $items, $args ) {
// we are done working with menu, so add the title filter back
add_filter( 'the_title', 'wpse309151_title_update', 10, 2 );
return $items;
}
// this filter fires after nav menu item creation is done
add_filter( 'wp_nav_menu_items', 'wpse309151_add_title_filter_non_menu', 10, 2 );

| I have a query as shown below:
```
<?php
$query = new WP_Query( $wpplnum );
while( $query->have_posts() ): $query->the_post();
?>
<div class="carousel-item col-md-4 active">
<div class="card">
<img class="card-img-top img-fluid" src="http://placehold.it/800x600/f44242/fff" alt="Card image cap">
<div class="card-body">
<h4 class="card-title">Card 1</h4>
<p class="card-text">This is a longer card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
<p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
</div>
</div>
</div>
```
I want to add the `active` class only to the first loop item:
**`class="carousel-item col-md-4 active"`**
the remaining loop items will be without the `active` class:
**`class="carousel-item col-md-4"`** | **I'd use the `current_post` property of the `WP_Query` class instance**, which in your case is the `$query`. So here I check if `$query->current_post` is greater than or equals to `1`:
```
<div class="carousel-item col-md-4 <?php echo $query->current_post >= 1 ? '' : 'active'; ?>">
```
