261,307 | <p>I'm going to be setting up a custom post type on a site (for job vacancies) and I'm going to create a separate menu item on the site's main nav using categories, and i'll use a 'jobs' category to effectively have the jobs menu item running as a second blog.</p>
<p>What i would like is to have it so when the client adds a job in the back end, the created post under this custom-post-type automatically has the category 'jobs' applied to it, regardless of any additional categories they use – so the posted jobs automatically get added to this menu item in the front end. </p>
<p>Is there a way of automatically adding a category to a custom-post-type? And also having it so any post with the category 'jobs' doesn't then show on the main blog page (which is going to be a news and market info page).</p>
<p>Any help would be awesome.</p>

Emily | To answer the first question (pre-populate a CPT with a Cat) you could add following function to functions.php .*(make backup first svp)*
In the code below *movies* is the Custom Post Type and *horror* is the Category.
Please change to own preferences.
```
/**

// Get the Category ID
$id = $idObj->term_id;
// Set now the Category for this CPT
wp_set_object_terms( $post_id, $id, 'category', true );
}
}// end function
```

*I would then make a function which hides the meta-box in the back-end for this specific CPT. (so no one can add/change the category, but that is only useful when you use only 1 category pro posting)*

*Ps, to clarify why I am not a fan of using `id` numbers directly:*
* It happens that a category is deleted for whatever reason and afterwards it seems a mistake and the same category needs to be created again.
* When a new category is created *(even with the same name)* it will get another `id` number and then *(when you use the number itself directly in any code)* your functions are not working anymore because of the wrong `id` number. |
261,313 | <p>I have installed wordpress in the sub-directory /www/html/wordpress/ (and not at /www/html/) and the solution given here <a href="https://wordpress.stackexchange.com/questions/261080/how-to-get-rid-of-index-php/261089#261089">How to get rid of index.php</a> didn't work on this server.</p>

| I'm trying to "POST" data from my Form through ajax to a mysql database.
This code is hooked to the "after\_setup\_theme" action:
```
add_action("wp_ajax_ajax_anmeldung", "ajax_anmeldung");
add_action("wp_ajax_nopriv_ajax_anmeldung", "ajax_anmeldung");
function ajax_anmeldung() {
echo "<script>
alert('hey');
</script>";
die();
}
```
And this is the JS code that calls it:
```
$('#teilnahme_form').submit(function(e){
e.preventDefault();
var name = document.getElementById("name").value;
jQuery.ajax({
type:"POST",
url: window.ajaxurl,
data: {
action: "ajax_anmeldung",
name : name
},
success:function(data){
alert(data);
}
});
});
```
When I run this I get returned a "0", nothing more.
When I tried: <http://my-domain.com/wp-admin/admin-ajax.php?action=ajax_anmeldung>
I also get a "0".
I read all the others post on here surrounding this topic, but nothing seemed to help me, or I overlooked something really important.
Cheers | Please try this:
Add the following in your theme's functions.php
```
add_action( 'init', 'tnc_aj_scripts' );
function tnc_aj_scripts() {
wp_register_script( "ajax_anmeldung_script", get_template_directory_uri(). '/my-ajax.js', array('jquery'), '1.0', true);
wp_localize_script( 'ajax_anmeldung_script', 'mYAjax', array( 'ajaxurl' => admin_url( 'admin-ajax.php' )));
wp_enqueue_script( 'jquery' );
wp_enqueue_script( 'ajax_anmeldung_script' );
}
add_action("wp_ajax_ajax_anmeldung", "ajax_anmeldung");
add_action("wp_ajax_nopriv_ajax_anmeldung", "ajax_anmeldung");
function ajax_anmeldung() {
$result['one'] = 'Hey';
$result = json_encode($result);
echo $result;
die();
}
```
Create a .js file in your theme directory called my-ajax.js and put the following inside that file:
```
jQuery('#teilnahme_form').submit(function(e){
e.preventDefault();
var name = document.getElementById("name").value;
jQuery.ajax({
type:"post",
dataType : "json",
url : mYAjax.ajaxurl,
data: {
action: "ajax_anmeldung",
name : name
},
success:function(data){
alert(data.one);
}
});
});

Edit 1
======
The `functions.php` as asked:

function loadThemerequirements()
{
load_theme_textdomain( 'testTheme', get_template_directory() . '/languages' );
}
endif;
add_action( 'after_setup_theme', 'loadThemerequirements' );
```
Update1
-------
The translations files were moved and renamed like that:
[](https://i.stack.imgur.com/3iXlO.png)
Still Same result.
Edit 2:
=======
This is not a child theme but a from-scratch made one.
Edit 3:
=======
I tried renaming the .po and .mo files as `el_GR.po` and `el_GR.mo` still same result. I also tried to rename them in to `testTheme/el_GR.po` and `testTheme/el_GR.mo` without any success.
Update 2
--------
The theme is in this git repository: <https://github.com/pc-magas/testTheme>
Edit 1
------
I changed my 404 page (that has some text to be translated into greek) like that:
```
<?php
get_header();
?>
<div class="fullpage_center">
<div>
<h1>404</h1>
<p><?php _e('The requested page does not exist.','testTheme');?></p>
</div>
</div>
<?php
wp_reset_query(); //resetting the page query
get_footer();
?>
```
A sample of my page and the translated text is:
[](https://i.stack.imgur.com/Ap6Yg.png)
As you can see still no result. | 1. Change your translate file name to `el_GR.po` and `el_GR.mo`:
```
el_GR.po in: testTheme\languages\el.po
el_GR.mo in: testTheme\languages\el.mo
```
2. In 404.php file for print text you should write code like this (add textdomain):
```
<?php _e('The requested page does not exist.', 'testTheme'); ?>
```
Second parameter is textdomain. |

261,409 | <p>I'm using ajax in a plugin for a front-end form.
But it only works if I place the <code>add_action("wp_ajax_..."</code> in the plugin loader.
I would like to register the call in another file. </p>
<p>I have tried: </p>
<pre><code>function my_plugin_init() {
if ( ! is_admin() ) {
require( dirname( __FILE__ ) . '/inc/my-plugin-functions.php' );
}
}
//add_action( 'wp_loaded', 'my_plugin_init' );
add_action( 'init', 'my_plugin_init' );
</code></pre>
<p>But neither <code>add_action</code> hook seems to work. Ajax fails because it cannot find the ajax function in <code>inc/my-plugin-functions.php</code>. </p>
<p>If I place the ajax function in the plugin loader, everything works as expected:</p>
<pre><code>function my_plugin_etc() {
$title = sanitize_text_field( $_POST['title'] );
$meta = update_post_meta(1234, 'test_key', $title);
if ( $meta != false )
echo json_encode(array('status' => 'success', 'message' => 'Title added as postmeta.') );
else
echo json_encode(array('status' => 'error', 'message' => 'There was a problem.' ) );
wp_die();
}
add_action("wp_ajax_my_plugin_etc", "my_plugin_etc");
</code></pre>
<p>I'd rather not put the ajax function in the plugin loader. </p>
<p>What is the proper hook to use to include a file so that the ajax function in that file is registered?</p>

| I'm using ajax in a plugin for a front-end form.
But it only works if I place the `add_action("wp_ajax_..."` in the plugin loader.
I would like to register the call in another file.
I have tried:
```
function my_plugin_init() {
if ( ! is_admin() ) {
require( dirname( __FILE__ ) . '/inc/my-plugin-functions.php' );
}
}
//add_action( 'wp_loaded', 'my_plugin_init' );
add_action( 'init', 'my_plugin_init' );
```
But neither `add_action` hook seems to work. Ajax fails because it cannot find the ajax function in `inc/my-plugin-functions.php`.
If I place the ajax function in the plugin loader, everything works as expected:
```
function my_plugin_etc() {
$title = sanitize_text_field( $_POST['title'] );
$meta = update_post_meta(1234, 'test_key', $title);
if ( $meta != false )
echo json_encode(array('status' => 'success', 'message' => 'Title added as postmeta.') );
else
echo json_encode(array('status' => 'error', 'message' => 'There was a problem.' ) );
wp_die();
}
add_action("wp_ajax_my_plugin_etc", "my_plugin_etc");
```
I'd rather not put the ajax function in the plugin loader.
What is the proper hook to use to include a file so that the ajax function in that file is registered? | *Any* action that fires before the AJAX call is made will work. Generally speaking, `init` is good choice.
You mention that the ajax call is made from a "front-end form". If that form is available to end-users who are **not** logged in, then you need to use:
```
add_action ('wp_ajax_nopriv_my_plugin_etc', 'my_plugin_etc') ;
```
See [wp\_ajax\_nopriv\_{$\_REQUEST[‘action’]}](https://developer.wordpress.org/reference/hooks/wp_ajax_nopriv__requestaction/).
**Edit**
Must be my lack of sleep, because I should have seen this earlier.
`is_admin()` returns `false` during an invocation of `admin-ajax.php`. Thus, change your `my_plugin_init()` to be:
```
function my_plugin_init() {
if ( ! is_admin() || wp_doing_ajax ()) {
require( dirname( __FILE__ ) . '/inc/my-plugin-functions.php' );
}
}
add_action( 'init', 'my_plugin_init' );
```
[wp\_doing\_ajax()](https://developer.wordpress.org/reference/functions/wp_doing_ajax/) was introduced in WP 4.7.
If your plugin needs to work in version of WP before that, then change it to:
```
function my_plugin_init() {
if ( ! is_admin() || (defined( 'DOING_AJAX' ) && DOING_AJAX)) {
require( dirname( __FILE__ ) . '/inc/my-plugin-functions.php' );
}
}
add_action( 'init', 'my_plugin_init' );
```
The advantage of `wp_doing_ajax()` over the pre-4.7 test (if you can get away with only supporting 4.7+) is that applies the [wp\_doing\_ajax](https://developer.wordpress.org/reference/hooks/wp_doing_ajax/) filter to the value of `defined( 'DOING_AJAX' ) && DOING_AJAX` which can give you finer control over whether you want to consider yourself within an ajax context. However, this extra control is probably not necessary in your case.
Finally, if `inc/my-plugin-functions.php` **only** contains code related to AJAX, then you remove `! is_admin() ||` from the `if` condition. |

| I'm am currently trialling the new (as of 2017) core API built into Wordpress. My setup is reasonably simple:
```
+---------+ +------+ +---------+
|Wordpress|<-->|Guzzle|<-->| App |
|(API) | +------+ |(PHPSlim)|
+---------+ +---------+
```
Guzzle will be operating through a local loopback (/etc/hosts set up to see the api as a local resource).
The major players in the WP space for cacheing (WP Super Cache, W3, etc) don't appear to do anything around the API. My understanding is that they essentially create snapshots of a rendered page and skip over any php (including db calls) for future requests.
So...
The question is, is it possible to apply a level of cache to the API calls in WP? The site is reasonably static, so ideally I don't want to ping the DB for every request.
I have examined the headers returned by WP and no cacheing indicators are present. I have also considered using wp\_cache functions or wp\_transient functions, but both seem to be a misuse of their functionality.

| I need to change a text content inside a contact form using jQuery, I know that the custom.js file that I'm using is connected as when I do a console.log I can see what I write.
When I select the paragraph that I need and change it's html content nothing happens, is it possible for the content to be overwritten by something later? Is there a way to prioritize my code?
```
jQuery("p.help-block.small").html("<p> ... </p>");
``` | In some instances, I'll run a *delayed init* function in a setTimeout like this:
```
var delay = setTimeout(function() {
jQuery("p.help-block.small").html("<p> ... </p>");
}, 100);
```
In the event that something is overwriting the html of that paragraph block on page load, this function will run 100 milliseconds after that, making yours the last change to the paragraph. 100 milliseconds is rather quick, so with other elements on the page loading, users may or may not notice the change.
I generally use this type of load with the elements hidden via CSS, and then fading them in when they've been "loaded" if there are a lot of elements that will will change in shape or size, e.g. going from three words to three paragraphs would make the page jump, so I may fade it in nicely instead.
Also, since you're calling **.html()** on the paragraph element, you don't need to include the paragraph tags within since the html you would be setting is already wrapped by paragraph tags. If you're just changing text, you could use **.text()** instead. However, if you're including line breaks or span elements within the paragraph, then **.html()** would be appropriate. |

| I want to show posts using WP\_Query functions. Also I want to add random order.
So I try
```

```
I can see 8 posts but it seems 'orderby' => 'rand' doesn't work. | It's quite some time since I worked with WordPress, but it seems to me that:
You're executing the query twice.
=================================
* First when you pass `$args` to the constructor during instantiation.
* Second when you call `query()`.
**With this, you're essentially overwriting the first query (the one that contains the orderby=rand).**
The [documentation of WP\_Query](https://codex.wordpress.org/Class_Reference/WP_Query) mentions that `get_posts()` is called if you use a parameter in the constructor, and it shouldn't be called twice:
>
> **&get\_posts()** – Fetch and return the requested posts from the database.
> Also populate $posts and $post\_count. Note: **This is called during
> construction if WP\_Query is constructed with arguments.** It is not
> idempotent and **should not be called more than once on the same query
> object.** Doing so may result in a broken query.
>
>
>
And the `query()` method's documentation states that it calls `get_posts()`, therefore it's called twice:
>
> **&query( $query )** – **Call** parse\_query() and **get\_posts()**. Return the
> results of get\_posts().
>
>
>
The solution:
=============
* You should either put everything in `$args`, or
* add the `orderby` parameter too to the `$wp_query->query(..)` call. |

```
I added the new code as Dave suggested (thanks!) and now it loads the wp editor, but when I click save to commit changes it doesn't save the wp\_editor content. Any ideas? | Here's an updated version of your original code, which solves the saving issue.
The reason that the content inside of the WP Editor was not saving was due to the value of the `textarea_name` parameter passed to `wp_editor()`.
This is wrong:
```
'textarea_name' => 'pw_intro',
```
It should look like this:
```
'textarea_name' => 'pw_settings[pw_intro]',
```
I also removed the echo from `wp_editor()`, fixed up the extra spaces around the text area, etc.
Full code example:
```
add_action( 'admin_menu', 'pw_add_admin_menu' );
add_action( 'admin_init', 'pw_settings_init' );
function pw_add_admin_menu( ) {
add_menu_page( 'wpset', 'wpset', 'manage_options', 'pset', 'pw_options_page' );

| I have a WordPress.org site. I am planning to use a new theme for the site. I have Installed the template and it is currently under the Themes folder.
The old theme is currently active. I would like to work on the new template and keep the old template active.
Once I finish working on the new theme, I would then like to make that active.
How can I achieve this? | You will need to [add term meta](https://developer.wordpress.org/reference/functions/add_term_meta/) to your categories. In this metafield you will store the string or number that you want to use as a base for your custom order ([tutorial](http://themehybrid.com/weblog/introduction-to-wordpress-term-meta)). Let's say you have generated a meta field called `my_cat_meta` which holds integers that say in which order you want them to be displayed.
Now you can pass this metakey to `wp_list_categories`. This function ultimately relies on [`get_terms`](https://developer.wordpress.org/reference/functions/get_terms/), which explains which arguments the function can take. You can limit the search to terms that have the metakey defined and order according to that metakey. This amounts to:
```
$args = array (
'title_li' -> '',
'meta_key' -> 'my_cat_meta',
'orderby'-> 'meta_key');
wp_list_categories ($args);
```
A slightly hacky way would be to use the 'description' field that is a default field in WP categories. Many themes don't display it, so you could use it to store metadata. In that case you could skip building your own metafield and use:
```
$args = array (
'title_li' -> '',
'orderby'-> 'description');

261,645 | <p>I'm struggling to see if this is natively supported, or if it's not the best place to implement this functionality - in my app (Laravel) or the same side as the API (WordPress).</p>
<p>Retrieving a single page (/about-us) via the slug is easy:</p>
<pre><code>/wp-json/wp/v2/pages?slug=about-us
</code></pre>
<p>But the issue comes with retrieving a sub/child page. Consider /about-us/child-page - this works perfectly fine in WordPress but retrieving the page via the Rest API seems impossible?</p>
<pre><code>/wp-json/wp/v2/pages?slug=about-us/child-page
/wp-json/wp/v2/pages?slug=%2Fabout-us%2Fchild-page%2F
</code></pre>
<p>No Results.</p>
<p>I can search for that individual page and get results, however if another page then shares that slug there's the potential for collisions.</p>
<pre><code>/wp-json/wp/v2/pages?slug=child-page
</code></pre>
<p>There's <code>get_page_by_path()</code> which allows you to search for pages via path which is exactly what I'm after - I can implement this using a custom REST API endpoint (<a href="https://www.coditty.com/code/wordpress-rest-api-how-to-get-content-by-slug" rel="noreferrer">https://www.coditty.com/code/wordpress-rest-api-how-to-get-content-by-slug</a>) but the returned result is not standard and not comparable to the WP-REST equivalent (See below) </p>

The <code>pagename</code> query variable does, however - but only one per query, which might be why it's not already leveraged for REST requests for hierarchical post types.</p>\n<p>There are a number of solutions and work-arounds. Please note that the code below has not been thoroughly tested, and the JavaScript in particular neglects important authentication and error-handling practices - it is intended for illustrative purposes only.</p>\n<hr />\n<h1>Make Multiple Requests</h1>\n<p>Your client can simply work through each path part and use the <code>_fields</code> parameter to minimize server load by only requesting ancestor posts' ID, then using that post ID as the <code>parent</code> argument for the subsequent request:</p>\n<pre class=\"lang-js prettyprint-override\"><code>async function wpse261645_fetchPage( path ) {\n const parts = path.split( '/' );\n const uri = '/wp-json/wp/v2/pages';\n let parent_id;\n\n for( let i = 0; i < parts.length; i++ ) {\n const params = new URLSearchParams( { slug: parts[i] } );\n\n if( i < parts.length - 1 )\n params.append( '_fields', 'id' );\n\n if( parent_id )\n params.append( 'parent', parent_id );\n \n const res = await fetch(\n `${uri}?${params}`,\n {\n method: 'GET',\n headers: { 'Content-Type': 'application/json' }\n }\n ).then( res => res.json() );\n\n if( i === parts.length - 1 )\n return res;\n\n parent_id = res[0].id;\n }\n}\n</code></pre>\n<hr />\n<h1>Modify <code>slug</code> REST Param/QV Mapping</h1>\n<p>This is probably the most appealing solution as it can effectively address the original issue directly without requiring special handling client-side.

| I'm struggling to see if this is natively supported, or if it's not the best place to implement this functionality - in my app (Laravel) or the same side as the API (WordPress).
Retrieving a single page (/about-us) via the slug is easy:
```
/wp-json/wp/v2/pages?slug=about-us
```
But the issue comes with retrieving a sub/child page. Consider /about-us/child-page - this works perfectly fine in WordPress but retrieving the page via the Rest API seems impossible?
```
/wp-json/wp/v2/pages?slug=about-us/child-page
/wp-json/wp/v2/pages?slug=%2Fabout-us%2Fchild-page%2F
```
No Results.
I can search for that individual page and get results, however if another page then shares that slug there's the potential for collisions.
```
/wp-json/wp/v2/pages?slug=child-page
```
There's `get_page_by_path()` which allows you to search for pages via path which is exactly what I'm after - I can implement this using a custom REST API endpoint (<https://www.coditty.com/code/wordpress-rest-api-how-to-get-content-by-slug>) but the returned result is not standard and not comparable to the WP-REST equivalent (See below)

Alternatively I can poll the API for each segment/page from my app to verify that each page exists and build up the data that way... | Unfortunately, this functionality is not natively supported out of the box. In detail, the problem is that most post types including `page` use the base `WP_REST_Posts_Controller` which maps the `slug` parameter to the `post_name__in` `WP_Query` argument, which does not facilitate resolving hierarchical slugs. The `pagename` query variable does, however - but only one per query, which might be why it's not already leveraged for REST requests for hierarchical post types.
There are a number of solutions and work-arounds. Please note that the code below has not been thoroughly tested, and the JavaScript in particular neglects important authentication and error-handling practices - it is intended for illustrative purposes only.
---
Make Multiple Requests
======================
Your client can simply work through each path part and use the `_fields` parameter to minimize server load by only requesting ancestor posts' ID, then using that post ID as the `parent` argument for the subsequent request:
```js
async function wpse261645_fetchPage( path ) {
const parts = path.split( '/' );
const uri = '/wp-json/wp/v2/pages';
let parent_id;
for( let i = 0; i < parts.length; i++ ) {
const params = new URLSearchParams( { slug: parts[i] } );
if( i < parts.length - 1 )
params.append( '_fields', 'id' );
if( parent_id )
params.append( 'parent', parent_id );
const res = await fetch(
`${uri}?${params}`,
{
method: 'GET',
headers: { 'Content-Type': 'application/json' }
}
).then( res => res.json() );
if( i === parts.length - 1 )
return res;
parent_id = res[0].id;
}
}
```
---
Modify `slug` REST Param/QV Mapping
===================================
This is probably the most appealing solution as it can effectively address the original issue directly without requiring special handling client-side. But it's a bit convoluted and experimental due to the number of moving parts involved and my own lack of familiarity with the REST API - I'm totally open to suggestions and improvements!
Before the `WP_REST_Posts_Controller` executes a query to retrieve the items corresponding to the request, it runs the query args and the request object through [the `rest_{$this->post_type}_query` filter](https://developer.wordpress.org/reference/hooks/rest_this-post_type_query/). We can leverage this filter to selectively re-map `slug` as necessary for chosen post-types or controllers.
It's also necessary to adjust the `slug` parameter's schema, parsing and sanitization routine for the relevant controllers such that it doesn't strip out `/`s or `%2F`s from the slug value or trip validation errors. I don't *think* that this should create any compatibility issues as the only parts of the schema and parameter registration that are touched are swapping out their sanitization callbacks - the changes should be near invisible to clients and discovery, and wholly backwards-compatible with the original functionality (unless someone's been relying on the REST API to transform `/`s in slugs into `-`s) - but I haven't tested it thoroughly.
Parsing, Schema, and Sanitization Adjustments (to keep the `/`s)
----------------------------------------------------------------
```php
function wpse261645_sanitize_nested_slug( $slug ) {
// Exploding slugs, as one does.
$slug_parts = array_map( 'sanitize_title', explode( '/', $slug ) );
return implode( '/', $slug_parts );
}
function wpse261645_parse_nested_slug_list( $slugs ) {
$slugs = wp_parse_list( $slugs );
return array_unique( array_map( 'wpse261645_sanitize_nested_slug', $slugs ) );
}
function wpse261645_nested_slug_schema( $schema ) {
$schema['slug']['arg_options']['sanitize_callback'] = 'wpse261645_sanitize_nested_slug';
return $schema;
}
add_filter( 'rest_page_item_schema', 'wpse261645_nested_slug_schema' );
function wpse261645_nested_slug_collection_params( $params ) {
$params['slug']['sanitize_callback'] = 'wpse261645_parse_nested_slug_list';
return $params;
}
add_filter( 'rest_page_collection_params', 'wpse261645_nested_slug_collection_params' );
```
Remapping the `slug` REST Param to Query Variables
--------------------------------------------------
Now that `/`s are persisted in the `slug` parameter, we can map the values into a variety of different queries:
```php
function wpse261645_remap_slug_param_qv( $args, $request ) {
$slugs = $request->get_param( 'slug' );
// If the `slug` param was not even set, skip further processing.
if( empty( $slugs ) )
return $args;
// Pull out hierarchical slugs into their own list.
$nested_slugs = [];
foreach( $slugs as $index => $slug ) {
if( strpos( $slug, '/' ) !== false ) {
$nested_slugs[] = $slug;
unset( $slugs[ $index ] );
}
}
if( count( $slugs ) ) {
$args['post_name__in'] = $slugs;
if( count( $nested_slugs ) ) {
$args['wpse261645_compound_query'] = true;
$args['post__in'] = array_map( 'url_to_postid', $nested_slugs );
add_filter( 'posts_where', 'wpse261645_compound_query_where', 10, 2 );
}
}
else {
unset( $args['post_name__in'] );
if( count( $nested_slugs ) === 1 )
$args['pagename'] = $nested_slugs[0];
elseif( count( $nested_slugs > 1 ) )
$args['post__in'] = array_map( 'url_to_postid', $nested_slugs );
}
return $args;
}
add_filter( 'rest_page_query', 'wpse261645_remap_slug_param_qv', 10, 2 );
function wpse261645_compound_query_where( $where, $query ) {
global $wpdb;
if( ! isset( $query->query['wpse261645_compound_query'] ) )
return $where;
return preg_replace(
"/ AND ({$wpdb->posts}.post_name IN \([^)]*\)) AND ({$wpdb->posts}.ID IN \([^)]*\))/",
' AND ($1 OR $2)',
$where
);
}
```
The logic above handles a number of different situations depending on the value of `slug`:
* Any number of flat slugs are mapped into the `post_name__in` QV as per normal.
* A single hierarchical slug will be mapped into the `pagename` QV, letting `WP_Query` natively handle the path resolution.
* A list of hierarchical slugs will be resolved via `url_to_postid()` and mapped into the `post__in` QV. The lookups add additional overhead.
* A list of intermixed hierarchical and flat slugs will be mapped into the `post__in` and `post_name__in` QVs respectively and the WHERE clause modified to OR these conditions instead of ANDing them. Hierarchical slugs will be resolved to IDs, adding additional overhead.
In summary, the most efficient queries are the product of passing `slug` as a single hierarchical slug, or any number of flat slugs in a list. Lists of hierarchical or intermixed slugs will result in additional overhead.
As an added benefit, this implementation also inherently facilitates explicitly requesting a top-level slug by including a `/`. E.g. `?slug=foobar` would return all posts with the slug `foobar` as per usual, but `?slug=/foobar` will return just the post with the slug `foobar` which has no parent.
---
Use a HEAD Request to the Web Path
==================================
**This is a horrible dirty hack** that relies on conventions outside of the REST API - ones which may incur a substantial overhead and which [some sites may be prone to disabling](https://wordpress.stackexchange.com/questions/211817/how-to-remove-rest-api-link-in-http-headers) to boot - **I strongly recommend against doing this**. Doubly so in any code intended for distribution; you will end up with a lot of unhappy users.
By default, WordPress returns a number of `Link` HTTP headers in responses to content requests, one of which being the REST route to the resource or collection corresponding to the content. As such it's possible to resolve any nested slug path to a REST resource within 2 requests by leveraging WordPress's frontend permalink routing:
```js
async function wpse261645_fetchPage( path ) {
let uri = `/wp-json/wp/v2/pages/?slug=${path}`;
if( path.includes( '/' ) ) {
const web_res = await fetch( `/${path}`, { method: 'HEAD' } );
const link_header = web_res.headers.get( 'Link' ).split( ', ' )
.find( val => val.includes( ' rel="alternate"; type="application/json"' ) );
uri = link_header.substring( 1, link_header.indexOf( '>' ) );
}
return fetch(
uri,
{
method: 'GET',
headers: { 'Content-Type': 'application/json' }
}
).then( res => res.json() );
}

| Server upgrading Friday, which will kill my existing WP 3.1 blog. So I’m installing 4.7.3 fresh in new subdirectory of existing WP 3.1 domain/site AND using the same database. Domain is a subweb. Server is running PHP 5.3. (New one will run 5.6) Once working, I’ll point the domain at the new directory. (Not sure whether subweb/shared db might affect this?)
I did mod the wp-config file with db info and memory use limits. Other than that, the entire install is fresh out of the box. No theme files here other than those included with 4.7.3 (although the old blog is running Thesis 1.8). No plugins other than stock akismet.
Got the following errors:
>
> Warning: require\_once(/users/domain.com/htdocs/directory/new
> subdirectory/wp-load.php) [function.require-once]: failed to open
> stream: No such file or directory in
> /users/domain.com/htdocs/directory/new
> subdirectory/wp-admin/install.php on line 36
>
>

> /users/domain.com/htdocs/directory/new
> subdirectory/wp-admin/install.php on line 36
>
>
>
Looking at the newly installed subdirectory, I saw ONLY folders:
```
wp-admin
wp-content
wp-includes
```
Next I tried uploading all files again. Same thing. So I selected the following files (without also selecting the above-named directories) and uploaded:
```
index.php
license.txt
readme.html
wp-activate.php
wp-blog-header.php
wp-comments-post.php
wp-config.php
wp-cron.php
wp-links-opml.php
wp-load.php
wp-login.php
wp-mail.php
wp-settings.php
wp-signup.php
wp-trackback.php
xmlrpc.php
```
And I get a nearly identical error msg:
>
> Warning:
> require(/users/domain.com/htdocs/directory/subdirectory/wp-includes/load.php)
> [function.require]: failed to open stream: No such file or directory

No idea what's going on here, hoping to learn how to fix it.
Any help appreciated! | It could be 2 things
Most like it's your file permissions. It is probably that your apache isn't able to open the files set files to 0644 and directories 0755.
The other problem could be your php version. Since you are upgrading to a new server, why not get the php in version 7? php 5.6 hit end of life 2 months ago. |

| So I am trying to display just the notes and the audio which are showing up with "AUDIO" and "TRANSCRIPT" as the output with a link to download them.
The issue I am having is that this also out put the featured image and the names of the uploaded PDF and MP3 show like this:
newyear2 (name of the featured image)
honest-wage (name of the audio file)

Any help would be appreciated! Thanks! | Now that I see you were hooking into `plugins_loaded`, this makes sense because it is fired much earlier than `wp_enqueue_scripts`. It is expected that your function would return 0 at this point.
See [here](https://codex.wordpress.org/Plugin_API/Action_Reference#Actions_Run_During_a_Typical_Request) and [here](https://wordpress.stackexchange.com/questions/162862/how-to-get-wordpress-hook-run-sequence) for the order in which actions are generally fired.
Try to [add an action](https://developer.wordpress.org/reference/functions/add_action/) at `wp_enqueue_scripts` with a late priority to make sure it runs after other enqueued scripts. Then you can [deregister](https://developer.wordpress.org/reference/functions/wp_enqueue_script/#notes) the script and register again with new parameters.

<p>I have a shortcode [person] with features name, age, location, phone, and description. I want to list my 50 friends on a page. Each feature of the person needs to be styled in html and the same on all. Each person returns the same info with about 10 different tags, etc.</p>
<p>Is it super inefficient (processing) to have a page with 50 people:</p>
<p>[person name="Doug Vander" age="60" location="United States" phone="1119992929"]Doug has been my friend for a long time.......[/person]</p>
<p>....
[person name="Lastperson"].......[/person]</p>
<p>Is there a better way to list info I re-use all the time?</p>

| I've been using shortcodes for cutting down on the amount of html I have in my visual editor.
I have a shortcode [person] with features name, age, location, phone, and description. I want to list my 50 friends on a page. Each feature of the person needs to be styled in html and the same on all. Each person returns the same info with about 10 different tags, etc.
Is it super inefficient (processing) to have a page with 50 people:
[person name="Doug Vander" age="60" location="United States" phone="1119992929"]Doug has been my friend for a long time.......[/person]
....
[person name="Lastperson"].......[/person]
Is there a better way to list info I re-use all the time? | If you use Adaptive Images plugin for WordPress, you would just make one inline css for all viewport widths using the biggest image and then it does all the work on the server. You do nothing to your markup but in the Adaptive Images plugin settings you enter your breakpoints, so it will serve small images to small devices and so forth.
If you use Adaptive Images it would be:
```
/**

function the_other_idea_good_heavens_change_this_function_name() {
global $post;
if ( ! has_post_thumbnail( $post->ID ) ) return; //exit if there is no featured image

?>
```
Somehow I need to be able to get the $eventDate in the last loop. | As discussed in the comments, instead of using the `ID` query argument to get each `'calp_event'`-type post individually, you can pass an array of IDs to `post__in` in order to grab them all at once, thus reducing the number of database transactions in your code to 2.
By creating an array mapping post IDs to event start dates from the results of your 3rd-party table query, you can easily obtain the value to pass to `post__in` by using `array_keys()` to get an array of just post IDs. Then later in the loop, you can look up the start date using the same post-ID-to-start-date map.
Since you're looping through query results and using template tags in a manner similar to WordPress's "Loop", you might also consider using a new `WP_Query` object instead of `get_posts()` to allow you to use a more conventional "Loop" logic to display your results.
```
global $wpdb;
$today = date('Y-m-d');
$events = $wpdb->get_results( "SELECT * FROM " . $wpdb->prefix . "calp_events WHERE start >= '$today' ORDER BY start ASC LIMIT 5" );
// Create an array using event post IDs as keys and start dates as values
$eventDates = array();
foreach( $events as $event ) {
$eventDates[ $event->post_id ] = $event->start;
}
// Query for the 'calp_event' posts indicated by the earlier query.
// Since the keys of $eventDates are the post IDs returned by the previous query,
// array_keys( $eventDates ) will return an array consisting of those IDs
$eventQuery = new WP_Query( array(
'post_type' => 'calp_event',
'post__in' => array_keys( $eventDates )
) );
// Use conventional Loop logic to display your results
if( $eventQuery->have_posts() ) {
while( $eventQuery->have_posts() ) {
$eventQuery->the_post();
// Accessing the $eventDates array with the current post ID as a key will produce
// the event start date which that ID is mapped to.
echo $eventDates[ get_the_ID() ] . ' ' . the_title() . '<br>';
}
// Reset global post data so we don't muck up the main query
wp_reset_postdata();
}
else {
echo 'No upcoming events!';
}
```
You could reduce this to a single query by using more advanced SQL to grab all of the necessary posts and event start-dates in one go. |

Here are 2 main ways to make that happen
1. **Type Cast** - `$values_x[] = (string) $series[0]['data'][$i][0]`
2. **Double Quote** - `$values_x[] "{$series[0]['data'][$i][0]}"`
Also, you might want to check for null first and assign a default
```
$values_x = !empty($values_x) ? $values_x : array('2010');
```
If you want to make the whole array a string, use `implode`
```
"values" => implode(', ', $values_x)
```
If you have multiple integers, this will output '2010, 2011'. Replace the comma and space with what you want placed between the pieces.

<p>The section I am talking about is <code>wp-admin > Appearance > Customize > Additonal CSS</code></p>
<p>We basically want to add a disclaimer to our clients about using that section, and I wanted to do it the Wordpress way, and not hack anything using jQuery (to add it) or in core.</p>

| I was trying to dig into this deeper, but I couldn't find any useful ways/hooks to add a little disclaimer above the Additional CSS code editor in the Wordpress Customizer. If anyone has a starting point of how i can add something simple like that, it would be greatly appreciated.
The section I am talking about is `wp-admin > Appearance > Customize > Additonal CSS`
We basically want to add a disclaimer to our clients about using that section, and I wanted to do it the Wordpress way, and not hack anything using jQuery (to add it) or in core. | Yep. I was able to show it by default using:
```
<?php
add_action('customize_controls_print_styles', function() {
?>
<style id="custom-css">
#sub-accordion-section-custom_css .description {
display: block !important;
}
</style>
<?php
});
```

261,935 | <p>I am developing a simple ranking plugin. Every post has it's own like count, and these counts are saved as custom-fields. </p>
<p>The problem is, no matter how much i research, i still couldn't find the proper way to manipulate theme's design in order to display post meta as i like. I've found some methods about changing theme's content.php file but it doesn't make sense because i want this plugin to work on every theme. Also in wordpress codex, it's told that i can do this by using template tags in the loop however index.php page which i can customize loop in, is not also included to my plugins directory.</p>
<p>What should i do in order to display post's ranking meta properly for all themes ? </p>

| I'm trying to rename and rearange the **Widgets** panel in WP Customizer area (apperance > customizer). So far I've only tried to rename the section, I would also like to move it to the bottom.
I'm using this code:
```
$wp_customize->get_section('widgets')->title = __( 'Sidebar & Footer widgets' );
```
Here's the complete code:
```
function my_customize_register() {
global $wp_customize;
//Remove various sections
$wp_customize->remove_section( 'fl-js-code-section' ); // JavaScript code box
$wp_customize->remove_section( 'fl-head-code-section' ); // Head code box
$wp_customize->remove_section( 'fl-header-code-section' ); // Header code box
$wp_customize->remove_section( 'fl-footer-code-section' ); // Footer code box
$wp_customize->remove_section( 'custom_css' ); // Additonal css box
// Rename various sections
$wp_customize->get_section('widgets')->title = __( 'Sidebar Footer widgets' );
}
add_action( 'customize_register', 'my_customize_register', 11);
```
But when I save and reload customizer I keep getting the following warning
>
> Warning: Creating default object from empty value in /home/siteid4/public\_html/\_test4/wp-content/themes/bb-theme-child/functions.php on line 51
>
>

Line 51 is the code renaming the widgets section.
The weird thing is that there are various section NOT from wordpress, they are added by other plugins. Those I have no problem renaming, it's only the WP sections I am having trouble with.
Any idea on how to rename and move this section? | Figured it out. Use "get\_panel" not "get\_section"
```
$wp_customize->get_panel('widgets')->title = __( 'Sidebar & Footer widgets' );

| I already have found [a working solution](https://wordpress.stackexchange.com/a/59957/25187) for my question, but **the problem is that it neutralizes** [another function](https://wordpress.stackexchange.com/a/94820/25187) that adds the category base into the custom post type permalinks, and I need boths, so **I must to merge them somehow**. How to do that?
This is the code that adds the .html extention to the custom post types:
```
//Create the rewrite rules like post-type/post-name.html
add_action( 'rewrite_rules_array', 'rewrite_rules' );
function rewrite_rules( $rules ) {
$new_rules = array();
foreach ( get_post_types() as $t )
$new_rules[ $t . '/([^/]+)\.html$' ] = 'index.php?post_type=' . $t . '&name=$matches[1]';
return $new_rules + $rules;
}
//Format the new permalink structure for these post types.
add_filter( 'post_type_link', 'custom_post_permalink' ); // for cpt post_type_link (rather than post_link)
function custom_post_permalink ( $post_link ) {
global $post;
$type = get_post_type( $post->ID );
return home_url( $type . '/' . $post->post_name . '.html' );
}
//And then stop redirecting the canonical URLs to remove the trailing slash.
add_filter( 'redirect_canonical', '__return_false' );
```
And this is the code that adds the category base to a *cources* custom post type (see [a similar solution](https://wordpress.stackexchange.com/a/108647/25187), and [another](https://stackoverflow.com/a/23702560/1354580)):
```
//Change your rewrite to add the course query var:
'rewrite' => array('slug' => 'courses/%course%')
//Then filter post_type_link to insert the selected course into the permalink:
function wpa_course_post_link( $post_link, $id = 0 ){
$post = get_post($id);
if ( is_object( $post ) ){
$terms = wp_get_object_terms( $post->ID, 'course' );
if( $terms ){
return str_replace( '%course%' , $terms[0]->slug , $post_link );
}
}
return $post_link;
}
add_filter( 'post_type_link', 'wpa_course_post_link', 1, 3 );
``` | Lets take these functions and paraphrase them into english, then put them in the order they're ran. I'm going to deliberately avoid using PHP in this answer, but a basic understanding of PHP will be necessary:
```
When the `post_type_link` filter runs: // the add_action calls
run: `wpa_course_post_link` as it has priority 3 // function wpa_course_post_link(....
if the object is a post
and that post has a course term
search for %course% in the URL string and replace it
Then, run `custom_post_permalink` as it has priority 10: // function custom_post_permalink(...
Ignore the URL we got given and construct a brand new one by returning the post_type + "/" + posts name + ".html"
```
So `custom_post_permalink` doesn't add `.html` to the end of your URLs as you thought it did, it creates a whole new URL. If you changed the priority from 3 to 11, your .html URLs will work, but your course URLs will not as `%course%` was replaced.
Luckily the `wpa_course_post_link` function provides a much better template for how to do this. Insted of grabbing the course terms and doing a string replace, just add .html to the end of the `$post_link` string and return it
So instead if we write it out as pseudocode in plain english, we might get this:
```
When the `post_type_link` filter runs:
run: `wpa_course_post_link` as it has priority 3
if the object is a post, then:
if that post has a course term then:
search for %course% in the URL string and replace it
then add ".html" to the end
```

| I have a Wordpress menu that are both being used as a normal menu with page name that links to the page. I want to echo the same registered menu, but without the page name. To be clear, I still want the anchorlink, but I do not want any text contained within the anchorlink.
```
<li><a href="the-page-link"></a></li>
```
The reason I want this is because I style the anchorlinks as small circles.
Is this possible? I tried to clear the content in css, but that does not affect the anchorlink when the page name is echoed in the HTML. | Lets take these functions and paraphrase them into english, then put them in the order they're ran. I'm going to deliberately avoid using PHP in this answer, but a basic understanding of PHP will be necessary:
```
When the `post_type_link` filter runs: // the add_action calls
run: `wpa_course_post_link` as it has priority 3 // function wpa_course_post_link(....
if the object is a post
and that post has a course term
search for %course% in the URL string and replace it
Then, run `custom_post_permalink` as it has priority 10: // function custom_post_permalink(...
Ignore the URL we got given and construct a brand new one by returning the post_type + "/" + posts name + ".html"
```
So `custom_post_permalink` doesn't add `.html` to the end of your URLs as you thought it did, it creates a whole new URL. If you changed the priority from 3 to 11, your .html URLs will work, but your course URLs will not as `%course%` was replaced.
Luckily the `wpa_course_post_link` function provides a much better template for how to do this. Insted of grabbing the course terms and doing a string replace, just add .html to the end of the `$post_link` string and return it
So instead if we write it out as pseudocode in plain english, we might get this:
```
When the `post_type_link` filter runs:
run: `wpa_course_post_link` as it has priority 3
if the object is a post, then:
if that post has a course term then:
search for %course% in the URL string and replace it
then add ".html" to the end
```

262,100 | <p>I have 10 thousand of users about 98% of these users never published a post (i mean post not comments). </p>
<p>I need a way to mass delete users with 0 posts.</p>
<p>The method must count all posts included custom post types and has to use proper WordPress function to delete a user as if they were manually deleted in the dashboard and not just drop a table/row on mysql, since that might cause unexpected results.</p>
<p>There's <a href="https://wordpress.org/plugins/no-posts-user-delete/" rel="noreferrer">an old plugin</a> that does this but doesn't consider all post types so can't really be used.</p>

| I have 10 thousand of users about 98% of these users never published a post (i mean post not comments).
I need a way to mass delete users with 0 posts.
The method must count all posts included custom post types and has to use proper WordPress function to delete a user as if they were manually deleted in the dashboard and not just drop a table/row on mysql, since that might cause unexpected results.
There's [an old plugin](https://wordpress.org/plugins/no-posts-user-delete/) that does this but doesn't consider all post types so can't really be used.
Any help appreciated. | If you have a large number of users to delete, you might consder using the [wp user delete](https://wp-cli.org/commands/user/delete/) **wp-cli** command to avoid script timeouts.
[Here's](https://stackoverflow.com/a/8155865/2078474) an example of a SQL query to delete all users **without posts of any type and status**.
You can therefore try this ~~untested~~ one-liner:
```
wp user delete $(wp db query "SELECT ID FROM wp_users WHERE ID NOT IN (SELECT DISTINCT post_author FROM wp_posts ) AND ID NOT IN (1,2,3)" | tail -n +2 ) --reassign=1
```
or in expanded form:
```
wp user delete $(wp db query
"SELECT ID
FROM wp_users
WHERE ID NOT IN (
SELECT DISTINCT post_author FROM wp_posts
) AND ID NOT IN (1,2,3)" | tail -n +2
) --reassign=1
```
Note that we added an extra `AND ID NOT IN (1,2,3)` restriction to make sure these users are not deleted (e.g. admin users). You will have to adjust it to your needs and also the table prefix `wp_`.
When I briefly tested this for couple of users, I noticed I had to add the `tail -n +2` part to avoid the top 3 lines in the header and the table border of the `wp db query` output.
Here we reassign all posts to user 1, to avoid the notice:
```
--reassign parameter not passed. All associated posts will be deleted. Proceed? [y/n]
```
Hope you can adjust it further to your needs, like relaxing the user delete conditions by adding `WHERE post_status = 'publish'`.
**Note:** Remember to backup before testing! |

if(get_post_meta( $post->ID, 'nb_postredirect', true ) != "")

header('Location: '.get_post_meta( $post->ID, 'nb_postredirect', true ));
wp_die();
die();
}

add_action( 'the_post', 'nb_checkredirect' );

| I have a super simple requirement here. I have added a meta field to all posts that will allow a url to be used to redirect the post (i have reasons for doing it this way). I am trying to trigger this on the action "the\_post", but for some reason it doesnt seem to fire. Here is what ive added
```
function nb_checkredirect($post)
{
if(get_post_meta( $post->ID, 'nb_postredirect', true ) != "")
{
header('Location: '.get_post_meta( $post->ID, 'nb_postredirect', true ));
wp_die();
die();
}
}
add_action( 'the_post', 'nb_checkredirect' );
```
I have checked what gets output to the PHP error log and there doesnt appear to be anything going wrong. | You need to use [wp\_script\_is](https://codex.wordpress.org/Function_Reference/wp_script_is) in order to check if the library you are willing to use has already been included by another plugin. As you can see the handle is important, if you change it to whatEverIWant.js, it will not recognize the library. |

| I want to conditionally add a body class depending on what template is being used.
I can't figure out why the following code is not working...
```
function damsonhomes_body_classes( $classes ) {
if (is_page_template('single.php')) {
$classes[] = 'sans-hero';
}
return $classes;
}
add_filter( 'body_class', 'damsonhomes_body_classes');
```
Thanks all | The [`is_page_template()`](https://developer.wordpress.org/reference/functions/is_page_template/) function is the incorrect function to use in this case as it checks against [Page Templates](https://codex.wordpress.org/Pages#Page_Templates) and `single.php` is just a normal template, not a page specific one, usually meant for posts.
The function you're probably looking to use instead is [`is_single( $optional_posttype )`](https://developer.wordpress.org/reference/functions/is_single/) which will look for singular view of a post type, `post` by default.
```
if( is_single() ) {
/** ... **/
}
```
You could also check against the basename if you *really* wanted to:
```
global $template;
$template_slug = basename( $template );
if( 'single.php' === $template_slug ) {
/** ... **/
}

i can't fully test it because of the functions being called by your theme, but try it out.
If this does work you you can pull out the article content. Replace all the content in your current loop.php with the content above but only from
```
<!-- article -->
```
to
```
<!-- /article -->
```
Since that would be in your new loop.php, you'll take it out of the main page. |

| I'm saving my CPT in [`private` status](https://github.com/nanodesigns/nanosupport/blob/v0.3.3/includes/ns-set-environment.php#L355-L377). So the transition would be from `pending` to `private`. Thing is, when the post was first submitted and is pending there's a date of that submission on the `post_date` field in db. But when the post got published, the date updated with the current date.
I want to keep the original date of the submission of the post even the post privately published later.
So I did something like below:
```
function mycpt_keep_pending_date_on_publishing( $new_status, $old_status, $post ) {
if( 'mycpt' === $post->post_type && 'pending' === $old_status && 'private' === $new_status ) :

// Update the post
$modified_post = array(

);
// Update the post into the database
wp_update_post( $modified_post );
endif;
}
add_action( 'transition_post_status', 'mycpt_keep_pending_date_on_publishing' );
```
But it's not working. What can be the reason? | @Howdy\_McGee is on the right track in his comment: by the time [transition\_post\_status](https://developer.wordpress.org/reference/hooks/transition_post_status) is fired, the post has already been updated (i.e., written to the db).
What you need to do is hook into [wp\_insert\_post\_data](https://developer.wordpress.org/reference/hooks/wp_insert_post_data/), **instead of** `transition_post_status`, as follows:
```
add_filter ('wp_insert_post_data', 'mycpt_keep_pending_date_on_publishing', 10, 2) ;
function
mycpt_keep_pending_date_on_publishing ($data, $postarr)
{
if ($data['post_type'] != 'mycpt') {
return ($data) ;
}
// this check amounts to the same thing as transition_post_status(private, pending)
if ('private' != $data['post_status'] || 'pending' != $postarr['original_post_status']) {
return ($data) ;
}
$pending_datetime = get_post_field ('post_date', $data['ID'], 'raw') ;
$data['post_date'] = $pending_datetime ;
$data['post_date_gmt'] = get_gmt_from_date ($pending_datetime) ;
return ($data) ;
}
```
**Note:** I used the same function name as you did, but the body of that function is different. |

| I am trying to get rig of the `Disqus` script on my front page, but unfortunately I cannot manage how to do this.
Here is a little story of the steps I've done.
1. Find the script name in the source code files of the plugin
wp\_register\_script( 'dsq\_count\_script', plugins\_url( '/media/js/count.js', **FILE** ) );
wp\_localize\_script( 'dsq\_count\_script', 'countVars', $count\_vars );
wp\_enqueue\_script( 'dsq\_count\_script', plugins\_url( '/media/js/count.js', **FILE** ) );
2. Add an action for the `wp_print_scripts` hook
```
add_action('wp_print_scripts', array($this, 'deregister_unused_scripts'), 100);
```
3. Implement `deregister_unused_scripts` function
```
public function deregister_unused_scripts()
{
wp_dequeue_script('dsq_count_script');
wp_deregister_script('dsq_count_script');
}
```
Still doesn't work.
I also tried another hook
```
add_action('wp_footer', array($this, 'deregister_unused_scripts'), 100);
```
But this didn't help as well, I still get an output in the footer.
```
<script type='text/javascript'>
/* <![CDATA[ */
var countVars = {"disqusShortname":"myname"};
/* ]]> */
</script>
<script type='text/javascript' src='http://myurl.net/wp-content/plugins/disqus-comment-system/media/js/count.js?ver=4.7.3'></script>
```
What can be wrong ?
**EDIT**
Here is the action used to register the plugin script.
```
add_action('wp_footer', 'dsq_output_footer_comment_js');
``` | When attempting to dequeue a script, we need to hook in after the script is enqueued, but before it's printed. In this case, the Disqus plugin is using the `wp_footer` hook at a priority of 10 to enqueue the scripts. The footer scripts get printed during `wp_footer` at a priority of 20.

``` | It depends on your theme. To find out exactly which file to edit, add the following code to your `header.php` file inside `/wp-content/themes/nameofyourtheme`:
```
<!-- <?php global $template; print_r($template); ?> -->
```
You can then view the page in question's source and see a comment that tells you the name of the file, which will also be somewhere inside your theme's folder structure.
Once you open that file, it is possible that it's calling another file - WordPress themes sometimes use template parts - if this is the case, the PHP code in the area you're troubleshooting will have a call to `get_template_part` and you'll need to find that separate PHP file.

Any help is appreciated! | Since you need to edit theme files, you'll first want to determine whether you're using a custom-built theme or something that was downloaded from somewhere. If it was downloaded from somewhere, you'll need to create a [child theme](https://codex.wordpress.org/Child_Themes) (basically, you just create a new `style.css` file which only needs to contain comments at the top, which let WordPress recognize it as a theme you can activate - and then you copy whichever file you're editing, probably `header.php`, into your theme and make edits there). This way whenever your main theme is updated your child theme will still apply your changes.
Then, in header.php, you'll change code that should look something like this (it may be longer but will contain `wp_nav_menu`):
```
wp_nav_menu(array('theme_location' => 'header'));
```
to a conditional:
```

Explanation:
Using WordPress's `current_time("N G")` gives you N, which is a day of the week, with Monday=1 through Sunday=7, as well as G, which is the hour of the day, with midnight=00 through 11 PM=23.
If your show is more than one hour you'll want to edit the show start and end values above.
You'll need to make sure WordPress is set to use your local time zone to ensure that things happen at the time you expect. You can do that in Settings > General.
Finally, this new code looks for 2 separate menus. If your show is on, it will pull from a *new* menu which you need to create. If your show isn't on, it will pull from the old/existing menu.
To create the new menu: in your (child) theme's `functions.php` file, add
function radio\_show\_live\_menu() {
register\_nav\_menu('radio\_show\_live\_menu', \_\_('Radio Live Menu'));
}
add\_action('init', 'radio\_show\_live\_menu');
You can then copy the existing menu into the new one and add the extra link. |
262,339 | <p>I'm using Advanced Custom Fields and Genesis and trying to modify a template to reflect a relationship between two custom post types (using their associated custom fields.) In this case, I have custom post types for "Staff" and "Reports", and for staff, I have the custom fields "first_name" and "last_name"; and associated with the "Reports" CPT, I also have two custom fields "primary_contact" and "associated_contact"— and in the "single-staff.php" template, I'd like to render a list of any associated reports in the sidebar that would include entries (post titles) for which <strong>that staff member</strong> is defined as <em>either</em> a "primary_contact" or an "associated_contact."</p>
<p>Thus, for example, if I've created "Tom Jones" as a staff member (an instance of the "Staff" post type), is it possible for me to define a query that outputs a list of reports for which "Tom Jones" is defined as a "primary_contact" and/or "associated_contact" in any instances of the "Reports" custom post type? I'm including a (very) rough concept for this query below:</p>
<pre><code>$args = array(
'meta_query' => array(
'relation' => 'OR',
array(
'post_type' => 'reports',
'meta_key' => 'primary_contact',
'meta_value' => '$this.full_name',
),
array(
'post_type' => 'reports',
'meta_key' => 'associated_contact',
'meta_value' => '$this.full_name',
)
)
);
$query = new WP_Query( $args );

Thanks! | There is another alt way to do this with CSS3. You would add a link to the WP Menu as normal but make the Location either `javascript:void(0);` or `#` so it doesn't go anywhere (I would say the `javascript...` is the better way to prevent anchor link from firing).
Then in your style.css or CSS doc you can get target those links via the `href` like
```
header .nav li a[href="#"], header .nav li a[href="#"]:hover,
header .nav li a[href="javascript:void(0);"],
header .nav li a[href="javascript:void(0);"]:hover {
text-decoration:none !important;
cursor: text !important
}
```

I have seen examples of this, but I am left wondering why this would ever be necessary unless WordPress assumes that a newly created role has certain capabilities until otherwise excluded.
For example, are all roles assumed to have the `read` capability unless the capability is explicitly excluded? I can use `get_role( $new_role )->capabilities;` to get a list of capabilities which are explicitly set, but this does not answer my question about how WordPress handles new roles. If no capabilities are explicitly set for a new role then this will return empty.
Must I exclude all capabilities I don't not want a role to have or does WordPress presume all capabilities to be false until they are set as true?
Edit: This question was inspired by [an example](https://developer.wordpress.org/reference/functions/add_role/#comment-941) on the developer site which sets a capability to false when a role is created. I can't see why this would be necessary.
```
$result = add_role(
'guest_author',
__( 'Guest Author', 'testdomain' ),
array(
'read' => true, // true allows this capability
'edit_posts' => true,
'delete_posts' => false, // Use false to explicitly deny
)
);
``` | I've found that the WordPress `has_cap()` function, which is relied on by functions like `user_can()` and `current_user_can`, explicitly returns false for empty capabilities.
Example: If a capability is passed as an argument using [`current_user_can()`](https://developer.wordpress.org/reference/functions/current_user_can/#source), this function will pass the capability to `has_cap()` and return the results:
```
return call_user_func_array( array( $current_user, 'has_cap' ), $args
```
[`has_cap()`](https://developer.wordpress.org/reference/classes/wp_user/has_cap/#source) will return false if the requested capability does not exist or the value is false:
```
foreach ( (array) $caps as $cap ) {
if ( empty( $capabilities[ $cap ] ) )
return false;
}
```
This is because the [`empty()`](http://php.net/manual/en/function.empty.php) function returns true in either case.

Unless I am mistaken about how these functions work, then it appears safe to say that **no default capabilities are attributed to a new role unless explicitly set to true**. It is not necessary to [explicitly deny](https://developer.wordpress.org/reference/functions/add_role/#comment-941) a capability when creating a new role with `add_role()` and I can't see any reason to do so. If a capability is not listed, the user will not have it. |

| I added some shortcode after the content using filter, like this:
```
add_filter( 'the_content', 'image_posts' );
```
but now that I run `has_shortcode` in another function, this returns false even though the shortcode is there (which was added using the above filter.
```
add_action( 'wp_head', 'gallery_style');
function gallery_style(){
if ( has_shortcode( $content, 'gallery' ) ) {
// enqueue style
// it fails for posts which add gallery using the_content
}
```
how can I test the `has_shortcode` for contents added using add\_filter? | For this, you'll actually want to utilize the `wp_enqueue_scripts` action instead of `wp_head`.
`wp_enqueue_scripts` is technically the proper way to add scripts and styles to your site. This action allows us to both register scripts and styles for later use (which is what we want here) and allows us to output scripts and styles to our page without hard coding. Also this matters because `wp_head` runs before `the_content` which means that you won't be able to modify the head once your code gets to `the_content`.
First let's register our style using the `wp_enqueue_scripts` action.
```
/**
* Register the gallery stylesheet for later use if our content contains the gallery shortcode.
*/
function enqueue_gallery_style(){
wp_register_style('gallery_style', get_stylesheet_directory_uri() . '/assets/css/gallery.css');
}
add_action('wp_enqueue_scripts', 'enqueue_gallery_style'); // register with the wp_enqueue_scripts action
```
We register the script using the `wp_register_style` function. In this case we'll make use of the first two parameters. The first is the name we want to give to the style so we can use it later. You can name it whatever you want. Here I've named it "gallery\_style". The second parameter is the url path to the stylesheet in your theme or plugin (make sure to update based on your specific path). Here are more details on [wp\_register\_style](https://codex.wordpress.org/Function_Reference/wp_register_style)
Now we can add another `the_content` filter in addition to your `image_posts` filter to perform the shortcode conditional check. Inside the check, if we find it, then we run the `wp_enqueue_style` function to enqueue our gallery style and add it to that specific page.
```
/**
* This function is used to check the_content to see if it contains any shortcodes
*
* @param $content
*
* @return string
*/
function shortcode_check( $content ) {
if ( has_shortcode( $content, 'gallery' ) ) {
wp_enqueue_style( 'gallery_style' ); // this is the same name we gave our gallery style when we registered it.
}
return $content; // Make sure you still return your content or else nothing will display.
}
add_filter( 'the_content', 'shortcode_check' );
```
More info on [wp\_enqueue\_style](https://developer.wordpress.org/reference/functions/wp_enqueue_style/)
**Method if you are trying to add admin-generated styles (eg. from customizer or other settings) that won't have a physical file.**
If you need to output styles that are generated via the admin (ie, colors) you can utilize the `wp_add_inline_style` function.
This function will allow you to add on styles to a registered stylesheet.
So in the case of our already registered gallery.css file above, we can add
`wp_add_inline_style( 'gallery_style', $user_css );` and it will add that as an inline style immediately after registered stylesheet.
Here `$user_css` would be the styles as a string **without** the `<style>` wrapper.
So in your case, you could register a stylesheet for gallery with some base styles and then use this function to add styles that would override those base styles.
```
function shortcode_check( $content ) {
if ( has_shortcode( $content, 'gallery' ) ) {
wp_enqueue_style('gallery_style');
wp_add_inline_style( 'gallery_style', $user_css ); // this will add our inline styles. Make sure to sanitize!!!
}
return $content; // Make sure you still return your content or else nothing will display.
}
```

262,491 | <p>I am making a theme that will be updateable via github.
<a href="https://github.com/pallazzio/skeleton" rel="nofollow noreferrer">https://github.com/pallazzio/skeleton</a></p>
<p>I am trying to use the plugin updater tutorial from smashing magazine, modified for updating a theme instead.

<p>I got it almost working. The update gets downloaded and installed to the correct folder. However, instead of leaving the same theme active, it is activating a new theme whose name is pallazzio-skeleton-b203a7f.</p>
<p>The weird part is that there is no folder created with that name. The files get installed to the correct place. The update is fully functional once I switch the active theme back to the original theme name.</p>
<p>The only thing I need to finish is how to make sure the current active theme doesn't change to a random name. I'm stuck.</p>

| I am making a theme that will be updateable via github.
<https://github.com/pallazzio/skeleton>
I am trying to use the plugin updater tutorial from smashing magazine, modified for updating a theme instead.
<https://www.smashingmagazine.com/2015/08/deploy-wordpress-plugins-with-github-using-transients/>
I got it almost working. The update gets downloaded and installed to the correct folder. However, instead of leaving the same theme active, it is activating a new theme whose name is pallazzio-skeleton-b203a7f.
The weird part is that there is no folder created with that name. The files get installed to the correct place. The update is fully functional once I switch the active theme back to the original theme name.
The only thing I need to finish is how to make sure the current active theme doesn't change to a random name. I'm stuck.
Any help would be greatly appreciated.
Here is the relevant part in functions.php
```
// Init theme updater
if( ! class_exists( 'Pallazzio_Theme_Updater' ) ){
include_once( 'updater.php' );
}
$updater = new Pallazzio_Theme_Updater( 'skeleton' );
$updater->set_username( 'pallazzio' );
$updater->set_repository( 'skeleton' );
//$updater->authorize( 'abcdefghijk1234567890' ); // auth code for private repos
$updater->initialize();
```
Here is the contents of updater.php
```

``` | For this, you'll actually want to utilize the `wp_enqueue_scripts` action instead of `wp_head`.
`wp_enqueue_scripts` is technically the proper way to add scripts and styles to your site. This action allows us to both register scripts and styles for later use (which is what we want here) and allows us to output scripts and styles to our page without hard coding. Also this matters because `wp_head` runs before `the_content` which means that you won't be able to modify the head once your code gets to `the_content`.
First let's register our style using the `wp_enqueue_scripts` action.
```
/**
* Register the gallery stylesheet for later use if our content contains the gallery shortcode.
*/
function enqueue_gallery_style(){
wp_register_style('gallery_style', get_stylesheet_directory_uri() . '/assets/css/gallery.css');
}
add_action('wp_enqueue_scripts', 'enqueue_gallery_style'); // register with the wp_enqueue_scripts action
```
We register the script using the `wp_register_style` function. In this case we'll make use of the first two parameters. The first is the name we want to give to the style so we can use it later. You can name it whatever you want. Here I've named it "gallery\_style". The second parameter is the url path to the stylesheet in your theme or plugin (make sure to update based on your specific path). Here are more details on [wp\_register\_style](https://codex.wordpress.org/Function_Reference/wp_register_style)
Now we can add another `the_content` filter in addition to your `image_posts` filter to perform the shortcode conditional check. Inside the check, if we find it, then we run the `wp_enqueue_style` function to enqueue our gallery style and add it to that specific page.
```
/**
* This function is used to check the_content to see if it contains any shortcodes
*
* @param $content
*
* @return string
*/
function shortcode_check( $content ) {
if ( has_shortcode( $content, 'gallery' ) ) {
wp_enqueue_style( 'gallery_style' ); // this is the same name we gave our gallery style when we registered it.
}
return $content; // Make sure you still return your content or else nothing will display.
}
add_filter( 'the_content', 'shortcode_check' );
```
More info on [wp\_enqueue\_style](https://developer.wordpress.org/reference/functions/wp_enqueue_style/)
**Method if you are trying to add admin-generated styles (eg. from customizer or other settings) that won't have a physical file.**
If you need to output styles that are generated via the admin (ie, colors) you can utilize the `wp_add_inline_style` function.
This function will allow you to add on styles to a registered stylesheet.
So in the case of our already registered gallery.css file above, we can add
`wp_add_inline_style( 'gallery_style', $user_css );` and it will add that as an inline style immediately after registered stylesheet.
Here `$user_css` would be the styles as a string **without** the `<style>` wrapper.
So in your case, you could register a stylesheet for gallery with some base styles and then use this function to add styles that would override those base styles.
```
function shortcode_check( $content ) {
if ( has_shortcode( $content, 'gallery' ) ) {
wp_enqueue_style('gallery_style');
wp_add_inline_style( 'gallery_style', $user_css ); // this will add our inline styles. Make sure to sanitize!!!
}
return $content; // Make sure you still return your content or else nothing will display.
}
```

Since with this CODE we will have Confirm Password field anyway, it doesn't make sense to show the password as you type.</p>\n\n<p>The reason WordPress core doesn't add a Confirm Password field is mainly because WordPress already shows the password text as you type it. Confirm Password field is the replacement for that feature and can be very useful (more secure) when the user is typing in front of someone else.</p>\n\n<p>So, I suggest you add the following CODE in addition to birgire's Plugin CODE:</p>\n\n<pre><code>add_action( 'login_enqueue_scripts', function ()\n{\n if ( ! wp_script_is( 'jquery', 'done' ) ) {\n wp_enqueue_script( 'jquery' );\n }\n // this line basically hides the password text\n wp_add_inline_script( 'jquery-migrate', 'jQuery(document).ready(function(){ jQuery( \"#pass1\" ).data( \"reveal\", 0 ); });' );\n}, 1 );\n</code></pre>\n\n<p>Of course, in this case WordPress will not auto generate the password for you, because obviously auto generating password & then hiding the password text doesn't make sense, as users will not be able to see it & type it in the Confirm Password field.</p>\n\n<p>Anyways, if you want to use this, then the final Plugin CODE will become:</p>\n\n<pre><code><?php\n/**\n * Plugin Name: Confirm New Login Password\n * Plugin URI: https://wordpress.stackexchange.com/a/262851/110572\n */\n\nadd_action( 'resetpass_form', function( $user )\n{ ?> <p class=\"user-wpse-pass2-wrap\">\n <label for=\"wpse-pass2\"><?php _e( 'Confirm new password' ) ?></label><br />\n <input type=\"password\" name=\"wpse-pass2\" id=\"wpse-pass2\" class=\"input\" \n size=\"20\" value=\"\" autocomplete=\"off\" />\n </p> <?php\n} );\n\nadd_action( 'validate_password_reset', function( $errors )\n{\n if ( isset( $_POST['pass1'] ) && $_POST['pass1'] != $_POST['wpse-pass2'] )\n $errors->add( 'password_reset_mismatch', __( 'The passwords do not match.' ) );\n} );\n\nadd_action( 'login_enqueue_scripts', function ()\n{\n if ( ! wp_script_is( 'jquery', 'done' ) ) {\n wp_enqueue_script( 'jquery' );\n }\n wp_add_inline_script( 'jquery-migrate', 'jQuery(document).ready(function(){ jQuery( \"#pass1\" ).data( \"reveal\", 0 ); });' );\n}, 1 );\n</code></pre>\n"

<p class="submit"><input type="submit" name="wp-submit" id="wp-submit" class="button button-primary button-large" value="<?php esc_attr_e('Reset Password'); ?>" /></p>
</form>
``` | It's tempting to unhide the `pass2` input but that's not enough.
In the file `/wp-admin/js/user-profile.js` the `bindPass1()` binds it to `pass1` that makes writing to it not possible. The `pass2` input is then hidden in `bindPasswordForm()` with `$('.user-pass2-wrap').hide();`
We can instead add our own input field to validate the password.
First we add it via the `resetpass_form` action:
```
add_action( 'resetpass_form', function( $user )
{ ?> <p class="user-wpse-pass2-wrap">
<label for="wpse-pass2"><?php _e( 'Confirm new password' ) ?></label><br />
<input type="password" name="wpse-pass2" id="wpse-pass2" class="input"
size="20" value="" autocomplete="off" />
</p> <?php
} );
```
Then we use the `validate_password_reset` hook to validate it:
```
add_action( 'validate_password_reset', function( $errors )
{
if ( isset( $_POST['pass1'] ) && $_POST['pass1'] != $_POST['wpse-pass2'] )
$errors->add( 'password_reset_mismatch', __( 'The passwords do not match.' ) );
} );
```
This is just using similar code as we have in the `wp-login.php` file.
This is how it looks in Icelandic, when there's a mismatch:
[](https://i.stack.imgur.com/krCkh.jpg)
**Plugin**
Create the plugin under:
```
/wp-content/plugins/wpse-confirm-password/wpse-confirm-password.php
```
and add the following code into that file:
```
<?php
/**
* Plugin Name: Confirm New Login Password
* Plugin URI: http://wordpress.stackexchange.com/a/262607/26350
*/
add_action( 'resetpass_form', function( $user )
{ ?> <p class="user-wpse-pass2-wrap">
<label for="wpse-pass2"><?php _e( 'Confirm new password' ) ?></label><br />
<input type="password" name="wpse-pass2" id="wpse-pass2" class="input"
size="20" value="" autocomplete="off" />
</p> <?php
} );
add_action( 'validate_password_reset', function( $errors )
{
if ( isset( $_POST['pass1'] ) && $_POST['pass1'] != $_POST['wpse-pass2'] )
$errors->add( 'password_reset_mismatch', __( 'The passwords do not match.' ) );
} );
```
Then activate the plugin from the backend as usual. |

<p>As you can see, I have defined the post type slug to be 'banaan'. The problem is, that the link wordpress generates (for instance, when clicking 'view' in wp-admin, the uri is <code>collection/$product_name</code>. I used to have /collection as base of the url, but I changed that to banaan for testing purposes, but it won't change. I have re-saved the permalinks. Am I missing something here?<br>
*Manually navigating to /banaan/$product_name redirects to /collection/$product_name and gives a 404</p>

| I have defined the following custom post type + taxonomy
```
$productTaxonomyLabels = [
'name' => __('Product Categories', 'byronposttypes'),
'singular_name' => __('Product Category', 'byronposttypes'),
];
$productTaxonomyArgs = [
'labels' => $productTaxonomyLabels,
'public' => true,
'publicly_queryable' => true,
'show_ui' => true,
'show_in_menu' => true,
'show_admin_column' => true,

'hierarchical' => true,
'rewrite' => [
'slug' => __('collections', 'byronposttypes'),
'with_front' => false,
'hierarchical' => true,
'ep_mask' => EP_CATEGORIES
],
];
register_taxonomy('collections', 'products', $productTaxonomyArgs);
register_taxonomy_for_object_type('collections', 'products');
$productLabels = [
'name' => _x('Products', 'post type plural name', 'byronposttypes'),
'singular_name' => _x('Product', 'post type singular name', 'byronposttypes'),
'menu_name' => _x('Collection', 'name in admin menu', 'byronposttypes'),
'add_new' => _x('Add new', 'product', 'byronposttypes'),
'add_new_item' => __('Add new product', 'byronposttypes'),
'new_item' => __('New product', 'byronposttypes'),
'edit_item' => __('Edit product', 'byronposttypes'),
'view_item' => __('View product', 'byronposttypes'),
'not_found' => __('No products found', 'byronposttypes'),
'not_found_in_trash' => __('No products found in trash', 'byronposttypes'),
'all_items' => __('All products', 'byronposttypes'),
'archives' => __('Product archives', 'byronposttypes'),
'attributes' => __('Product attributes', 'byronposttypes'),
];
$productSupports = ['title', 'editor', 'thumbnail'];
$productArgs = [
'labels' => $productLabels,
'description' => __('Products', 'byronposttypes'),
'public' => true,
'publicly_queryable' => true,
'show_ui' => true,
'menu_position' => 57,
'menu_icon' => 'dashicons-screenoptions',
'capability_type' => ['product', 'products'],
'hierarchical' => false,
'supports' => $productSupports,
'taxonomies' => ['banaan'],
'rewrite' => [
'slug' => 'banaan',
'with_front' => false,
],
'has_archive' => 'banaan',
];
register_post_type('products', $productArgs);
```
As you can see, I have defined the post type slug to be 'banaan'. The problem is, that the link wordpress generates (for instance, when clicking 'view' in wp-admin, the uri is `collection/$product_name`. I used to have /collection as base of the url, but I changed that to banaan for testing purposes, but it won't change. I have re-saved the permalinks. Am I missing something here?
\*Manually navigating to /banaan/$product\_name redirects to /collection/$product\_name and gives a 404 | File name should be `admin-ajax.php`
This file handles all the ajax requests. So, you should never remove this file.
Many features will stop working like autosave and many other that uses ajax if you remove this file. |

262,725 | <p>I made a mistake and changed the URL under settings -> General. After this Wordpress locked me out. I first added in the wp-congif.php file: </p>
<pre><code>define('WP_HOME','http://example.com');
define('WP_SITEURL','http://example.com');
</code></pre>
<p>This appeared to have fixed the issue but only if I was logged into Wordpress. Users could not enter to the website and they have a forbidden message. My URL to visit my test site would redirect me always to my homepage, etc. </p>
<p>I also resetted the htcaccess file but nothing seems to do the trick. I finally uploaded a full backup of my site and the problem is still there, nothing works and the site is completely broken. Any ideas?</p>
<p>My current htaccess file looks like this:</p>
<pre><code># BEGIN WordPress
<IfModule mod_rewrite.c>
