<p>I have a nav menu with a depth of 2.</p>
<pre><code>wp_nav_menu( array( 'theme_location' => 'primary_navigation',
'depth' => 2
) );
</code></pre>
<p>When I am active on a page in the nav menu that has no children, that <code>li</code> menu item has <code>active</code> appended. However, when the menu item has children, <code>has-children</code> is appended, but no 'active' or even a related class name.</p>
<pre><code><ul id="menu-main-top-navigation">
<li class="parent1"></li>
<li class="has-dropdown not-click">
<ul class="dropdown">
<li class="child1"></li>
<li class="child2"></li>
</ul>
</li>
<li class="parent3"></li>
<li class="parent4"></li>
<li class="active parent5"></li>
<li class="parent6"></li>
</ul>
</code></pre>
<p>In this case I am the page relating to menu item 'parent5'. This is fine. When I navigate to what is meant to be 'parent2', the class name is replaced completely with 'has-dropdown' so there is no differing class name or 'active'.</p>
<p>How can I fix this. Even to remove the JQuery in this case.</p>

I have a nav menu with a depth of 2.
```
wp_nav_menu( array( 'theme_location' => 'primary_navigation',
'depth' => 2
) );
```
When I am active on a page in the nav menu that has no children, that `li` menu item has `active` appended. However, when the menu item has children, `has-children` is appended, but no 'active' or even a related class name.
```
<ul id="menu-main-top-navigation">
<li class="parent1"></li>
<li class="has-dropdown not-click">
<ul class="dropdown">
<li class="child1"></li>
<li class="child2"></li>
</ul>
</li>
<li class="parent3"></li>
<li class="parent4"></li>
<li class="active parent5"></li>
<li class="parent6"></li>
</ul>
```
In this case I am the page relating to menu item 'parent5'. This is fine. When I navigate to what is meant to be 'parent2', the class name is replaced completely with 'has-dropdown' so there is no differing class name or 'active'.
How can I fix this. Even to remove the JQuery in this case.

Can you add the complete output code for the navigation menu. The code you pasted seems to be a stripped version. Moreover, WordPress adds 'current\_page\_item' class to the list item if it is currently being viewed.
For more info, check this [WordPress documentation](https://codex.wordpress.org/Function_Reference/wp_nav_menu#Backward_Compatibility_with_wp_page_menu.28.29) on classes added to Navigation menu items.

<p>I am currently working on a theme for a client and now just got into a problem: When I want to set an image (also existing/already uploaded images don't work) the editor just not accept it and don't set it as the post thumbnail for the post.</p>
<p>Any help would be appreciated.</p>
<p>EDIT:
Here is an screenshot for the case that somebody didn't know, what I am talking about:</p>
<p><img src="https://i.stack.imgur.com/k0DvD.png" alt="enter image description here"></p>
<p>It's like this <strong>before</strong> and <strong>after</strong> the "change". So what's going on there?</p>

I figured out it was because of an script that was delivered with the **Options Framework**. There was a little piece of code in my `functions.php` which caused wrong javascript to be loaded.
When you are having the same problem, be sure to search for something like `wp_enqueue_media();` or something of the following script, comment out and try to upload a thumbnail.
```
if( function_exists( 'wp_enqueue_media' ) ){
wp_enqueue_media();
} else {
wp_enqueue_style('thickbox');
wp_enqueue_script('media-upload');
wp_enqueue_script('thickbox');
}
```
Thanks for all answers, though.

<p>I'm quite new to WP theme development so I'm sorry if the answer for this question may seem obvious. </p>
<p>I'm developing a custom WordPress theme from scratch, and I'm stuck working on the menus. My header menu has some submenus that I'd like to style, but when I call the menu with the wp_nav_menu() function, the HTML output doesn't recognize them as submenus. </p>
<p>I mean, even if I built correctly the menus in the admin panel, the output I get is:</p>
<pre><code><ul>
<li>Item #1</li>
<li>Item #2</li>
<li>Item #3</li>
<li>Item #4</li>
<li>Item #5</li>
<li>Item #6</li>
</ul>
</code></pre>
<p>Item #4 and Item #5 are nested into a submenu under Item #3, for example, and I want them to be nested inside another ul, how they should be.
I'm sure it's a theme related problem, because everything works well by switching to a default theme. </p>
<p>This is how I use the wp_nav_menu() function:</p>
<pre><code>wp_nav_menu( array( 'theme_location' => 'header-menu',
'container_class' => 'navigator' ) )
</code></pre>
<p>Maybe I have to add something in functions.php, but I really don't know what. </p>
<p>Thank you all. </p>

<p>I use a random wp_query to load 3 posts from over 600 posts in total with this query.</p>
<pre><code> <?php
$args = array(
'post_type' => 'post',
'cat' => 1,
'orderby' => 'rand',
'posts_per_page' => 3
);
$all_posts = new WP_Query( $args );
while ( $all_posts->have_posts() ) : $all_posts->the_post();
get_template_part( 'content' );
endwhile;
?>
<?php wp_reset_postdata(); ?>
</code></pre>
<p>Works great, but it seems for a lot of people a lot of the same images popup in the random display over and over again. So it seems the random isn't really random. At least it doesn't feel this way. Is there a way to force Wordpress to skip random displayed images and load new ones? Or is it out of my hands in this case? I can't really find an answer online.</p>
<p>Thanks in advance! </p>

<p>I am trying to set up a <code>wp-cli.yml</code> file but every time I run the command, the file is ignored.</p>
<p>Where should the file be located?
And how should I call the command to use it?</p>
<p>I tried having a file in the project's root directory, as well as a folder above. I have also tried using the following file names:</p>
<p><code>wp-cli.local.yml</code>,
<code>wp-cli.yml</code></p>
<p>The I tried running something like:</p>
<pre><code>wp local core download
</code></pre>
<p>But I keep getting the following error:</p>
<blockquote>
<p>Error: This does not seem to be a WordPress install.
Pass --path=<code>path/to/wordpress</code> or run <code>wp core download</code>.</p>
</blockquote>
<p><strong>PS:</strong> I am not sure wp-cli questions are off topic because I see tons of questions about wp-cli with answers, and I also see that there's a wp-cli tag. If this questions is off topic, please let me know before down voting it, and I will remove it.</p>

**PS:** I am not sure wp-cli questions are off topic because I see tons of questions about wp-cli with answers, and I also see that there's a wp-cli tag. If this questions is off topic, please let me know before down voting it, and I will remove it.

**TL;DR**:
1. Run `wp --version --debug`
2. Check that `wp-cli.yml` was found
3. Check that the `ABSPATH` set by WP-CLI matches the directory where WP is installed
4. Look at `find_wp_root()` for hints about why it's finding the wrong folder

The docs say:

...so you should be able to use it in parent directories, not just in the directory where you call `wp` from. i.e., you should be able to have it several levels above the folder where Core is installed, and then call it from anywhere below the directory where `wp-cli.yml` is installed [[1](https://github.com/wp-cli/wp-cli/blob/5090616a38b920f1d1b71cf8046757749503424b/php/WP_CLI/Runner.php#L91)].
Was `wp-cli.yml` included?
==========================
You can find out by running `wp --version --debug`
* Found: `Debug: Using project config: /var/www/example.localhost/wp-cli.yml (0.012s)`
* NOT Found: `Debug: No project config found (0.014s)`
Is WP-CLI's `ABSPATH` set correctly?
====================================
*Note: This is the `ABSPATH` that WP-CLI defines internally, **not** the one from your `wp-config.php`*
WP-CLI's internal `ABSPATH` is what it uses to find WordPress [[2](https://github.com/wp-cli/wp-cli/blob/5090616a38b920f1d1b71cf8046757749503424b/php/WP_CLI/Runner.php#L565), [3](https://github.com/wp-cli/wp-cli/blob/5090616a38b920f1d1b71cf8046757749503424b/php/WP_CLI/Runner.php#L553)], so if it's wrong then you'll get the `This does not seem to be a WordPress install` error.
To find out if it's wrong, you can run `wp --version --debug` from a few different directories, and look at the `ABSPATH` output. Does it match the actual path to the folder where Core is installed?
Assuming the path to WP is `/var/www/example.localhost/web/wordpress/`, then:
* Correct: `Debug: ABSPATH defined: ABSPATH defined: /var/www/example.localhost/web/wordpress/ (0.013s)`
* Incorrect: `Debug: ABSPATH defined: /var/www/example.localhost/web/content/plugins/akismet/wordpress/ (0.019s)`
Keep in mind that any arguments passed via parameters (e.g., `wp --path=foo`) will override the values in `wp-cli.yml`.
Why is `ABSPATH` wrong?
=======================
There are probably lots of different causes for it being wrong, because it depends on how your folder structure is setup, the `path` defined in `wp-cli.yml`, etc.
`ABSPATH` is set to the value of `find_wp_root()`[[4], [5], [6]], so that's where you need to start troubleshooting.
You can read through `find_wp_root()` and mentally step through the code, looking for clues. If you have WP-CLI [installed via composer](http://wp-cli.org/docs/pull-requests/), then you can also edit `Runner.php` to add debugging output to `find_wp_root()`, use Xdebug, etc.
In my case, I had a Bash alias setup for `wp` that was passing `--path` to the command, which was overriding the `path` set in `wp-cli.yml`, but I'd forgotten about it.

Using `admin-ajax.php` means that the WordPress Core is loaded and available. WIthout that, you would need to hand load the files you need, which is a complicated process and prone to failure if you don't know the Core very, very well. And, how good are you with Javascript security?

1. It loads the WordPress Core, meaning you can use things like `$wpdb`
and `$WP_Query`. That is through about line 25.
2. It sends a few headers-- lines 37 - 41.
1. A content type header
2. A header to tell browsers not to cache the results
3. The interesting headers are those sent by [`send_nosniff_headers()`](https://codex.wordpress.org/Function_Reference/send_nosniff_header)
4. and [`nocache_headers()`](https://codex.wordpress.org/Function_Reference/nocache_headers).
3. The `admin_init` hook fires.
4. Core actions are defined and registered dynamically-- lines 46 - 73.
These won't be registered unless they are needed-- that is, unless
they are requested via `$_GET` or `$_POST`.
5. The "heartbeat" API hook fires-- line 75
6. The "logged in" status of the requesting user is checked and the
appropriate administrative or "no priviledge" hook is fired.
Items #1 and #6 are the primary reasons to use the AJAX API, in my opinion. You have the WordPress Core, which you almost certainly need, and you have the same login security system as with the rest of WordPress.

Specifically I'm hoping to generate sizes on the fly when a specific (old) image size is missing, but the original image is still in tact.
**Background:** A while back I cleaned house with images on a site in hopes of normalizing my image sizes. Totally forgetting about the various older auto-generated images that were soft-cropped. So now there are a couple hundred old images that aren't displaying.

If you have access to install, or if it is available on your server I would recommend using [WP-CLI](http://wp-cli.org/). It has a command to regenerate the media:
```
wp media regenerate
```
If not, you can try a plugin such as [Regenerate Thumbnails](https://wordpress.org/plugins/regenerate-thumbnails/)
Good luck!

If you are using the [save\_post](https://codex.wordpress.org/Plugin_API/Action_Reference/save_post) action hook; then you can prevent the code from executing during an autosave with the following conditional:
```
function do_not_autosave( $post ) {
// Check to see if we are autosaving
if (defined('DOING_AUTOSAVE') && DOING_AUTOSAVE)
return;
// Rest of the code here
}
add_action( 'save_post', 'do_not_autosave');
```

In the code you posted, the filter `ctc_post_type_item_args` gets applied to the `$args` array before it is passed into `register_post_type()`.
Putting a function into your themes `functions.php` and hooking it to the filter should do the trick:
```
function wpse_191003_ctc_post_type_item_args( $args ) {
$args['rewrite']['slug'] = "your_new_slug";
return $args;
}
add_filter( 'ctc_post_type_item_args', 'wpse_191003_ctc_post_type_item_args' );
```

I would like to password protect a page on my blog. Wordpress allows me to give one single password to each protected page. Is there a way to create more than one valid password to access that page?
|
In the code you posted, the filter `ctc_post_type_item_args` gets applied to the `$args` array before it is passed into `register_post_type()`.
Putting a function into your themes `functions.php` and hooking it to the filter should do the trick:
```
function wpse_191003_ctc_post_type_item_args( $args ) {
$args['rewrite']['slug'] = "your_new_slug";
return $args;
}
add_filter( 'ctc_post_type_item_args', 'wpse_191003_ctc_post_type_item_args' );
```

<p>For my theme development purposes I have a local WordPress installation that I run from a VM, accessed via, let's say, <code>http://local.app</code>. I also have a remote version of the site on a staging server, <code>http://staging.example.com</code>. </p>

<p>The only problem is that all media is getting 404 as for some reason all urls to the media files are linking to my local vm rather than the staging server. E.g. If I visit the media library and go to the "edit media" page, the "file url" reads as follows:</p>

Somewhere in the core, URLs get absolutely pathed when put into the database.
Why don't you just load all your images from your staging server? Have the staging server hold the files while your local mirrors it. Add the following to your `.htaccess` to your local uploads folder and the contents are as follows:
```
# Attempt to load files from production if they're not in our local version
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
# Replace http://example.com with your production site's domain name
RewriteRule (.*) http://example.com/wp-content/uploads/$1
</IfModule>

This will affect **logged-out** users, which defeats the purpose of caching in the first place.
The problem
-----------
When using page/browser caching with [T3 Total Cache](https://wordpress.org/plugins/w3-total-cache/) or likely other caching plugins, if you have already visited a page when logged out, you will be presented with the same logged-out version of the page, unless if you refresh the page.
You can reproduce this issue by:
1. Have caching enabled. Then, in incognito mode, visit a post.
2. Login to the site and then manually type the URL of that post into the address bar. The logged-out version of the page should appear.
This is obviously an issue you have any features available for logged-in users only (like comments, voting etc)...
Potential solution
------------------
The only potential solution I have is to add a query variable to the URL on every request. For example by adding a random value:
```
$key = rand();
$new_url = esc_url( add_query_arg( 'foo', $key ) );
```
I know how to manually add this variable to single queries but instead of altering every single instant of links, is there a way how to force this to every URL for logged-in users?

Since you already have the "Don't cache pages for logged in users" option activated, what about selecting `cache with validation` under `Cache Control Policy` for "HTML" content?
Explanation: Essentially, the "don't cache pages for logged in users" option should already be sending a `no-cache` header for your logged users only.
If a user has a cached page in its browser (as a non-logged user) and then tries to access the same page when logged in, the `cache with validation` option inside your "Cache Control Policy" setting for HTML contents should be sending the `must-revalidate` tag.
Hence, a logged in user would send `no-cache,must-revalidate`, always requesting a fresh page.
This is pretty much what @gmazzap explained with headers - but from a W3 Total Cache configuration perspective.

<p>The <a href="https://codex.wordpress.org/Function_Reference/get_post_meta" rel="nofollow">documentation</a> from <code>get_post_meta</code> makes it sound as if the <code>single</code> argument will determine whether or not meta values are returned in an array or not. For example:</p>
<pre><code>// If I set single to false, or leave it blank it's returned as an array
[my-meta] => Array
(
[0] => my-value
)
// If I set single to true, it's returned as a string
[my-meta] = my-value
</code></pre>
<p>This works fine if I'm only returning data for a single meta key...but fails if I want to return all of the meta data, but return them all as strings (single).</p>
<p>It would seem that the proper call to get all of the meta values with string values would be:</p>
<pre><code>$meta = get_post_meta( $transaction->ID, false, true );
</code></pre>
<p>But this returns with the array values and completely ignores the <code>single</code> value.</p>
<p>Why? Is there a way to get all of the meta data, but without the single element arrays? Those are unnecessary in my case.</p>
<p>EDIT: Just to clarify what I'm asking, I'd lie to get all of the meta like this:</p>
<pre><code>array() {
[my-meta-1] = my-value
[my-meta-2] = my-value
[my-meta-3] = my-value
[my-meta-4] = my-value
}
</code></pre>
<p>Rather than like this (which is the only behavior I seem to be able to get):</p>
<pre><code>array() {
[my-meta-1] => Array
(
[0] => my-value
)
[my-meta-2] => Array
(
[0] => my-value
)
[my-meta-3] => Array
(
[0] => my-value
)
[my-meta-4] => Array
(
[0] => my-value
)
}
</code></pre>

A function in PHP can only return a single value so there is no way to return <em>all</em> meta as <em>strings</em> (plural). It has to come out as an array, or an object. And that is what the function does-- you get a single value as a string or you get an array. If you don't specify a key then the code has no way to know which key you want so you get them all, by defaurl <strong><em>not</em></strong> single. When you are not retrieving single values, WordPress does not collapse the nested array. If that is what you want, take it up with the Core developers on Trac. In the meantime, collapse the array yourself:</p>\n\n<pre><code>$meta = get_post_meta(350);\nvar_dump($meta);\nforeach ($meta as $k => $v) {\n $meta[$k] = array_shift($v);\n}\n</code></pre>\n\n<p>Or:</p>\n\n<pre><code>foreach ($meta as &$v) {\n $v = array_shift($v);\n}\n</code></pre>\n\n<p>That may not bet he answer you hoped for, but I am pretty sure it is accurate.

This works fine if I'm only returning data for a single meta key...but fails if I want to return all of the meta data, but return them all as strings (single).
It would seem that the proper call to get all of the meta values with string values would be:
```
$meta = get_post_meta( $transaction->ID, false, true );
```
But this returns with the array values and completely ignores the `single` value.
Why? Is there a way to get all of the meta data, but without the single element arrays? Those are unnecessary in my case.
EDIT: Just to clarify what I'm asking, I'd lie to get all of the meta like this:
```
array() {
[my-meta-1] = my-value
[my-meta-2] = my-value
[my-meta-3] = my-value
[my-meta-4] = my-value
}
```
Rather than like this (which is the only behavior I seem to be able to get):
```
array() {
[my-meta-1] => Array
(
[0] => my-value
)
[my-meta-2] => Array
(
[0] => my-value
)
[my-meta-3] => Array
(
[0] => my-value
)
[my-meta-4] => Array
(
[0] => my-value
)
}
```

This doesn't make a lot of sense. A function in PHP can only return a single value so there is no way to return *all* meta as *strings* (plural). It has to come out as an array, or an object. And that is what the function does-- you get a single value as a string or you get an array. If you don't specify a key then the code has no way to know which key you want so you get them all, by defaurl ***not*** single. When you are not retrieving single values, WordPress does not collapse the nested array. If that is what you want, take it up with the Core developers on Trac. In the meantime, collapse the array yourself:
```
$meta = get_post_meta(350);
var_dump($meta);
foreach ($meta as $k => $v) {
$meta[$k] = array_shift($v);
}
```
Or:
```
foreach ($meta as &$v) {
$v = array_shift($v);
}
```
That may not bet he answer you hoped for, but I am pretty sure it is accurate. There might be a filter, but I doubt the effort would be worth it.

Not complicated, but a little tricky to get timing right.
Something like this should work, but you might need to experiment with priority to get the link to specific position on the bar:
```
add_action( 'admin_bar_menu', function ( $wp_admin_bar ) {
if ( ! is_admin() ) {
return;
}
/** @var WP_Admin_Bar $wp_admin_bar */
$wp_admin_bar->remove_node( 'view-site' );
$wp_admin_bar->add_menu( array(
'id' => 'view-site',
'title' => __( 'Visit Site' ),
'href' => home_url( '/' ),
) );
}, 31 ); // After `wp_admin_bar_site_menu()` at 30.
```

But when the image shows up on the page it's using http instead of https like the rest of the site.
When go to the [WP codex](https://codex.wordpress.org/Function_Reference/esc_url) to see the usage for esc\_url it shows me this under usage but I don't know the correct syntax to use to make the protocol forced to https:
```
<?php esc_url( $url, $protocols, $_context ); ?>

esc\_url never force the URL to protocol it's only checking and escaping the passed URL from invalid characters, the $protocols variable is an array of acceptable (white list) protocols not for forcing destination URL.
```
// Forcing URL to https instead of http
$YOUR_URL = esc_url($YOUR_URL);

When I call the `$wp_rewrite->rewrite_rules()`, the rule I just made isn't there. I've tried flushing them a handful of different ways, and even tried an extremely simple rule just to see if it was added, and still nothing.
|
Try this. You also don't want to include $wp\_rewrite->flush\_rules() inside your function as that would flush on every page load.
```
add_action('rewrite_rules_array', 'new_rewrite_rules');
function new_rewrite_rules($rules){
$newrules = array();
$newrules[ '^lists/([^/]*)/([^/]*)/?' = 'index.php?lists=$matches[1]&post=$matches[2]';
return $newrules + $rules;
}
```
If you want to flush the rules only once then try this:
```
add_action('init', 'flush_new_rule');
function flush_new_rule(){
global $wp_rewrite;
if(is_array(get_option('rewrite_rules')) && !array_key_exists('^lists/([^/]*)/([^/]*)/?$', get_option('rewrite_rules')){
$wp_rewrite->flush_rules( true );
};
}
```

<p>Because of the lack of documentation about <a href="https://codex.wordpress.org/Plugin_API/Filter_Reference/post_limits" rel="nofollow"><code>post_limits</code></a>, its hard to learn more about this function and when to use it.

<p>Based on my testing, post_limits does the same thing as using pre_get_posts </p>
<p>If i wanted to return 5 posts conditionally without paginating the remainder, would i use post_limits or pre_get_posts?</p>

Because of the lack of documentation about [`post_limits`](https://codex.wordpress.org/Plugin_API/Filter_Reference/post_limits), its hard to learn more about this function and when to use it. Never used it before or seen it used so maybe its not to be used?
```
function wpcodex_filter_home_post_limits( $limit, $query ) {
if ( ! is_admin() && $query->is_main_query() && $query->is_home() ) {
return 'LIMIT 0, 25';
}
return $limit;
}
add_filter( 'post_limits', 'wpcodex_filter_home_post_limits', 10, 2 );
```
Based on my testing, post\_limits does the same thing as using pre\_get\_posts
If i wanted to return 5 posts conditionally without paginating the remainder, would i use post\_limits or pre\_get\_posts?
|
Note that here you're overriding the paging of the main query, with the `posts_limits` filter, by using hardcoded values:
```
'LIMIT 0, 25'
```
where `0` is the offset and `25` is the number of posts to display.
So in this case I would just use `pre_get_posts` with
```
$query->set( 'posts_per_page', 25 );
```
and we don't have to worry about the paging.
>

If we later decide that pagination is necessary, then we would need to rework your `posts_limits` code. The `pre_get_posts` filter would work as is and we could therefore say that it's at least a more "future proofed" method.
Another thing: If you were using `get_posts()` or `WP_Query()` with *suppressed* filters, then the `posts_limits` filter wouldn't be available while the `pre_get_posts` hook would be accessible.

<p>So I've been tasked with making an "Image Advert" to be placed on a sidebar on this website. The client wants to have the ability to upload 5 images on to the ACF Options Page and then have a random image be pulled from there and displayed on the sidebar at random everytime the page refreshes.</p>
<p>I was wondering if it was possible for anyone to help me.</p>
<pre><code><?php
$rows = get_field('image_advert_repeater'); // get all the rows
$rand_row = $rows[ array_rand($rows, 1) ]; // get a random row
$rand_row_image = $rand_row['image_advert_images']; // get the sub field value
// Note
// $first_row_image = 123 (image ID)
$image = wp_get_attachment_image_src( $rand_row_image, 'full' );
// url = $image[0];
// width = $image[1];
// height = $image[2];
?>
<img src="<?php echo $image[0]; ?>" />
</code></pre>
<p>This is the code I'm currently trying to use to display the images. It's taken from the ACF Repeater documentation and I've editied it to use my repeater but I can't seem to get it to work. I've also tried adding 'options' to the end of the field names to see if that's the isssue but it just white screens the website on refresh.</p>

Just noticed the issue - since your ACF field is an options page, you need to pass the second argument `options` to `get_field` - add a bit of sanity checking too:
```
$rows = get_field( 'image_advert_repeater', 'options' );
if ( ! empty( $rows ) && is_array( $rows ) ) {
// Your code
}

Based on [this question](https://wordpress.stackexchange.com/questions/191120/how-to-check-if-widget-has-automatic-title/191154), I'm getting an error `Warning: Missing argument 2 for...`.
This happens for some widgets those are created by plugins.
-- Edit 1 --
Here's a simple widget that causes the error:
```
function my_new_widget_register() {
register_widget( 'my_new_widget' );
}
add_action('widgets_init', 'my_new_widget_register');
class my_new_widget extends WP_Widget {
function my_new_widget() {
// Instantiate the parent object
parent::__construct( false, 'my_new_widget' );
}
function widget( $args, $instance ) {
// Widget output
extract( $args );
$title = apply_filters('widget_title', $instance['title']);
echo $before_widget;
echo $title;
echo $after_widget;
}
}
```
The error is clearly caused by `$title`.
|
You don’t pass more than argument to that filter, so any callback expecting more than one will not get it. The core calls this filter always like this:
```
$title = apply_filters(
'widget_title',
empty($instance['title']) ? '' : $instance['title'],
$instance,
$this->id_base
);
```
But you are passing just `$instance['title']`. Add the missing parameters, and the error will vanish.
If you cannot change the widget, change the registration for the callback for the filter, and make the other arguments optional by setting a default value:
```
add_filter( 'widget_title', 'my_widget_title_filter', 10, 3 );
function my_widget_title_filter( $title, $instance = [], $id_base = '' ) {
if ( '' === $id_base )
return $title;
// do something with the title, then
return $title;
}
```

<p>I have an own class that deregisters all scripts and styles and creates 2 cached files one for scripts and one for styles that is registered in the end. This runs inside theme, my problem is that I cant move it into plugin, as soon as i move it into plugin it wont work.</p>
<p>currently this code works inside theme</p>

There's a much better and more reliable way than naming your plugin "ZZ" - use a delayed hook on `plugins_loaded`, which fires after all plugins are loaded:
```
function wpse_191178_plugins_loaded() {
// Do your stuff
}
add_action( 'plugins_loaded', 'wpse_191178_plugins_loaded', 100 );
```

Writing my first Wordpress plugin that uses a Class approach.
It is being called on a page via a shortcode. In testing, the shortcode is working and the shortcode specific php file is being loaded.
However, the 2 add\_action calls are not firing:
```
//Register Styles
add_action( 'wp_enqueue_style', array( $this, 'register_styles' ) );
//Register Scripts
add_action( 'wp_enqueue_script', array( $this, 'register_scripts' ) );
```
When I test with var\_dump, the register\_styles/scripts functions are not even running, yet all other functions called in \_\_contruct() are.
Here is the full code:
```
<?php
if ( ! defined( 'ABSPATH' ) ) exit; // Exit if accessed directly
add_action( 'plugins_loaded', array ( 'Lipstick_Consultation', 'init' ));
if (!class_exists('Lipstick_Consultation')){
class Lipstick_Consultation{
public static function init() {
$class = __CLASS__;
new $class;
}
/**
* @since 1.0
*/
public function __construct() {
//get contstants
$this->setup_constants();
//get file includes
$this->includes();
//Register Styles
add_action( 'wp_enqueue_style', array( $this, 'register_styles' ) );
//Register Scripts
add_action( 'wp_enqueue_script', array( $this, 'register_scripts' ) );
$this->register_shortcodes();
return $this;
}
/**
* Include our Class files
*
* @access private
* @since 1.0.0
* @return void
*/
private function includes() {
/****SHORTCODES****/
//[slider_person]
require_once LC_DIR . 'inc/shortcodes/slider.php';
}
/**
* Setup plugin constants
*
* @access private
* @since 1.0.0
* @return void
*/
private function setup_constants() {
// Plugin information
define( 'LC_VERSION', '1.0.0' ); // Current plugin version
define( 'LC_URL', plugin_dir_url( __FILE__ ) );
define( 'LC_DIR', plugin_dir_path( __FILE__ ) );
}
/**
* Register Styles
*
* @access public
* @since 1.0.0
* @return void
*/
public function register_styles() {
//main style file
wp_register_style( 'consultation_style', LC_URL . "assets/css/style.css", array(), time(), 'all' );
wp_enqueue_style( 'consultation_style' );
//styles for full page plugin
wp_register_style( 'lc_full_page_style', LC_URL . "assets/css/jquery.fullPage.css", array(), time(), 'all' );
wp_enqueue_style( 'lc_full_page_style' );
}
/**
* Register Scripts
*
* @access public
* @since 1.0.0
* @return void
*/
public function register_scripts() {
//Script that makes full width/height/page divs
wp_register_script( 'lc_full_page', LC_URL . "assets/js/jquery.fullPage{SUFFIX}.js", array( 'jquery' ), time() );
wp_enqueue_script( 'lc_full_page' );
}
private function register_shortcodes(){
add_shortcode("lipstick_person","shortcode_person_slider");
}
}
}?>
```
|
There is no action called `wp_enqueue_script`, it's `wp_enqueue_scripts`, plural, and both scripts and styles should be enqueued on that action.

<?php
/**

```
|
A quick solution: find your `content-product.php` find the below code
```
<a href="<?php the_permalink(); ?>">
<?php
/**
* woocommerce_before_shop_loop_item_title hook
*
* @hooked woocommerce_show_product_loop_sale_flash - 10
* @hooked woocommerce_template_loop_product_thumbnail - 10
*/
do_action( 'woocommerce_before_shop_loop_item_title' );
?>
<h3><?php the_title(); ?></h3>
<?php
/**
* woocommerce_after_shop_loop_item_title hook
*
* @hooked woocommerce_template_loop_rating - 5
* @hooked woocommerce_template_loop_price - 10
*/
do_action( 'woocommerce_after_shop_loop_item_title' );
?>
</a>
```
move the a tag like:
```
<?php
/**
* woocommerce_before_shop_loop_item_title hook
*
* @hooked woocommerce_show_product_loop_sale_flash - 10
* @hooked woocommerce_template_loop_product_thumbnail - 10
*/
do_action( 'woocommerce_before_shop_loop_item_title' );
?>
<h3><?php the_title(); ?></h3>
<?php
/**
* woocommerce_after_shop_loop_item_title hook
*
* @hooked woocommerce_template_loop_rating - 5
* @hooked woocommerce_template_loop_price - 10
*/
do_action( 'woocommerce_after_shop_loop_item_title' );
?>
<a href="<?php the_permalink(); ?>"></a>
```
Note: Use the customization in your theme/woocommerce directory otherwise changes will undo if plugin got update.
Hence above changes may depend on the theme you are using. if your theme already have woocommerce do changes accordingly.

<p>I <em>need</em> a function that I can use that will remove <div> and </div> tags from a string. I have tried <em>esc_attr()</em>, and even <em>wp_strip_all_tags()</em> --- none of them work. They all leave the <div> and </div> tags in the string - which causes certain social-media buttons to turn out in ways that <em>really</em> do not look good.</p>
<p>Any suggestions what to do?</p>

Use a PHP function to do this: <https://php.net/strip_tags>
example:
```
echo strip_tags("<div>my text</div>");

I'm creating a WordPress theme and my **functions.php** file is getting very big now. I managed to remove a lot of code by turning some functions into plugins but it is still huge.
I would like to be able to organize the code with *includes*. I tried a couple of things but it didn't work. It's like the files I included in my functions.php file are being ignored.
```
// Configure the WordPress Customizer
require(get_template_directory_uri() . '/admin/customizer/customizer.php');
```
The above code is supposed to call a file that's adding a function that creates sections, settings and controls in the WordPress Customizer. When the function is placed **directly into my functions.php file** everything works fine but when I try to include it, it does nothing.
The included file also contains *includes*, I don't know if this is of relevance.
*The above code is hooked on **after\_setup\_theme**, if you think I should do anything differently please tell me, I want to learn.*
|
I always break my functions.php up into more managable, specific functionality files, for instance, all footer related functions goes into a file called `footer-functions.php` and pagination functions goes into a file called `pagination-functions.php`. This way, my code stays organised, managable and I don't kill my `functions.php`. This however, is only related to theme specific functions, site specific functions goes into plugins in much more the same type of method
To come back to the point, at the end I include all my smaller specific function files into `functions.php` with `require_once()` as follow
```
require_once( 'footer-functions.php' );
require_once( 'pagination-functions.php' );
```
This is all you need. You should not hook this to any hook or add it in any function, it can have expected behavior which can lead to a broken site

<p>Is it possible to change permalinks on all posts created after a certain date? This because we don't want old URLs to break.</p>
<p>Now we have <code>/%year%/%month%/%postname%</code>
We want to have <code>/%postname</code></p>

Is it possible to change permalinks on all posts created after a certain date? This because we don't want old URLs to break.
Now we have `/%year%/%month%/%postname%`
We want to have `/%postname`
|
Your permalink structure is global; it is not a property of individual posts. There is no way to indicate that one post uses a certain permalink structure while another uses a different one.
This makes sense when you think about how WordPress processes requests. Using the new structure, WordPress maps the request to `index.php?name=$1` where `$1` is the post slug portion of the request. WordPress then queries the database for a post with a slug that matches the request.
If every post had its own permalink structure, WordPress would have to iterate over every single post until it found one with a permalink structure that matched the request.
What you can do is redirect your old permalinks to the new permalinks. There are a couple of ways you can go about doing this:
---
**.htaccess**
You can add the following to your `.htaccess` file, before the WordPress rewrite rules:
```
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^[0-9]{4}/[0-9]{2}/(.*)$ /$1 [R=301,L]
</IfModule>
```
This will match the `year/month/postname` structure and redirect to the `postname` structure.
**add\_rewrite\_rule**
You can use [`add_rewrite_rule`](https://codex.wordpress.org/Rewrite_API/add_rewrite_rule) to create an additional rule that matches your old permalink structure.
```
add_action('init', function() {
flush_rewrite_rules();
add_rewrite_rule('^([0-9]{4})/([0-9]{2})/(.*)$', 'index.php?name=$matches[3]', 'bottom');
});
```
This accomplishes the same thing as the `.htaccess` method. If you use this approach make sure you flush your rewrite rules by visiting the `Settings > Permalinks` page in your backend.
---
Regardless of which approach you use, the canonical URL for your posts will use the new permalink structure. Requests using the old permalink structure will be redirected to the new structure.
Search engines will eventually catch on to the change and index the new structure rather than the old structure. At that point, you can drop the additional rewrite rules, *so long as you don't have any internal links using the old structure*.
If you do have internal links using the old structure, I would use [this utility](https://interconnectit.com/products/search-and-replace-for-wordpress-databases/) to do a regex search and replace. Just make sure you make a backup of your database.
If you are concerned about inbound links using the old structure, there isn't much you can do other than keep the rewrite rules indefinitely.

Test Page Title

I believe that the page title you are talking about is the title from the page from the main query. `the_title()` filter (and `the_content()` filter for that matter) targets all the respective template tags regardless of query.
To avoid this, target only the main query and the specific page.
You can try the following inside your filter
```
if ( in_the_loop() && is_page( 'specific page' ) ) {
// Do what you need to do
}
```
EDIT
----
I just thought of this, haven't tested it, but you can check your title inside the filter against a known static title and then do something according to that
Example:
```
if ( $title == 'My known title' ) {
// Do something with the title
}
```

This what I've done:
```

function wpflex_setup() {
register_nav_menus( array(
'primary' => 'Primary Menu'
) );
}
endif;
wp_nav_menu( array(
'theme_location' => 'top-menu',
'container' => '',
'menu_class' => 'mainmenu pull-left',
) );
```
How to add class for `ul`?
|
You already did it the right way. If you take a look in the Documentation for [wp\_nav\_menu](https://developer.wordpress.org/reference/functions/wp_nav_menu/), you'll see that menu\_class is the right option for the UL's class:
```
wp_nav_menu( array(
'theme_location' => 'top-menu',
'container' => '',
'menu_class'=> 'mainmenu pull-left *add-your-class-here*'
) );
```

<p>I have been developing a WordPress website for a client, working from my own machine utilizing WAMP to create a local environment on which to work.</p>
<p>Now, the problem is that the website needs to go live. I understand how to use an FTP client, and that's not a problem. I have the details for the domain etc. There is an existing website already there, and I would like to know if it's possible to upload the new website while keeping the old one running, but that is not the main issue. </p>
<p>I have been having trouble transferring the website from one machine to another, and I believe that this has to do with properly exporting/importing the database. This is the area that I am struggling with. To make things even more difficult, I wish to upload the new website to the server but use the database that is already in place with the existing website, for the client's benefit. Is this possible? How would I achieve this? If it is not, what are my alternatives? </p>
<p>Apologies for the short essay, but I thought it best to paint as clear a picture of my situation as possible. Thanks in advance for time taken to read/respond to this. </p>

**Moving your sites**
My recommendation would be to use the the [duplicator](https://wordpress.org/plugins/duplicator/) plugin. Far and away the easiest method I've used to back-up, move, and restore sites from local to production or from one host to another.
If the old site is WordPress - sounds like it is, you may want to consider creating a sub-domain and then using [duplicator](https://wordpress.org/plugins/duplicator/) on the old site to back-up and then restore the old site to the new sub-domain.
```
mysite.com -> old.mysite.com
```
Then use [duplicator](https://wordpress.org/plugins/duplicator/) to back-up your local dev site and then restore it to the location of the original site.
**Connecting to the old DB**
Once you have both sites on your host mysite.com and old.mysite.com you could change the settings in the wp-config.php of the new site (now mysite.com) to point to the db of the old site (old.mysite.com) like so:
```
// wp-config.php
define ( 'DB_NAME', 'olddbname' );
define ( 'DB_USER', 'olddbusername' );
define ( 'DB_PASSWORD', 'olddbpassword' );
define ( 'DB_HOST', 'old.mysite.com' );
```
In fact you could probably just copy the DB definitions from the wp-config of old.mysite.com into the wp-config of the mysite.com.
* *I'd comment out the db definitions present for mysite.com.*
Can you clarify what you want to accomplish by doing this?
The problem with pointing the new site to the old db is that it will also use the old site theme etc. A sum zero really. If your just trying to get the posts and pages from the old site to the new, I'd use the export/import tools that come packaged with WordPress. There are also syndicate plugins ([FeedPress](https://wordpress.org/plugins/feedpress/) is my preferred one) that seem to be more robust than the WordPress import/export tools.

<p>I have a plugin that is using Class style programming. I'm completely stumped - scripts are being loaded on every single page, even if the plugin is not being used on that page.</p>
<p>Since the plugin should only run when one of its shortcodes are called, I don't understand why they are always being enqueued. The code is:</p>
<pre><code><?php

<p>If I understand what is happening, on the plugins_loaded hook the plugin is being instantiated. When the construct method is being called it is enqueing the scripts. That all makes sense.</p>
<p>When looking at other plugins it looks as though they use a similar structure, yet - their script files are only loaded when their plugin is being invoked on that page.</p>
<p>What am I doing wrong? Thanks!</p>

<p>Guys, I just cannot figure out how to do this. I made the following edits to the code:</p>

public function shortcode_person_slider_caller($atts, $content){
//register styles/scripts
$this->register_shortcode_requirements();
//run actual function for rendering
$content = shortcode_person_slider($atts);
return $content;
}
</code></pre>
<p>Then in the caller function the <code>shortcode_person_slider</code> is a function included in one of the require_once loaded files.</p>
<p>The function is firing (tested with a var_dump) in that function and it displays. Yet, the content is not displaying on the page (even though $content has all of the html markup).</p>
<p>Further, the script/style files are not being enqueued.</p>
<p>When testing, the <code>register_shortcode_requirements()</code> is firing, but each of the wp_enqueue_script hooks are not.</p>
<p>Any advice? Thank you!</p>

}
}
}
?>
```
If I understand what is happening, on the plugins\_loaded hook the plugin is being instantiated. When the construct method is being called it is enqueing the scripts. That all makes sense.
When looking at other plugins it looks as though they use a similar structure, yet - their script files are only loaded when their plugin is being invoked on that page.
What am I doing wrong? Thanks!
**UPDATE #1**
Guys, I just cannot figure out how to do this. I made the following edits to the code:
```
public function __construct() {
//get contstants
$this->setup_constants();
//get file includes
$this->includes();
//register plugin shortcodes
$this->register_shortcodes();
return $this;
}
/**
* Registers the styles and scripts for the shortcodes
*/
private function register_shortcode_requirements() {
//Register Styles
add_action( 'wp_enqueue_scripts', array( $this, 'register_styles' ) );
//Register Scripts
add_action( 'wp_enqueue_scripts', array( $this, 'register_scripts' ) );
}
/**
* Register Styles
*/
public function register_styles() {
//main style file
wp_register_script( 'consultation_style', LC_URL . "assets/css/style.css", array(), time(), 'all' );
wp_enqueue_script( 'consultation_style' );
//styles for full page plugin
wp_register_script( 'lc_full_page_style', LC_URL . "assets/css/jquery.fullPage.css", array(), time(), 'all' );
wp_enqueue_script( 'lc_full_page_style' );
}
/**
* Register Scripts
*/
public function register_scripts() {
//Script that makes div have a scrollbar
wp_register_script( 'lc_slim_scroll', LC_URL . "assets/js/jquery.slimscroll". SUFFIX . ".js", array( 'jquery' ), time() );
wp_enqueue_script( 'lc_slim_scroll' );
//Script that makes full width/height/page divs
wp_register_script( 'lc_full_page', LC_URL . "assets/js/jquery.fullPage". SUFFIX . ".js", array( 'jquery' ), time() );
wp_enqueue_script( 'lc_full_page' );
}
private function register_shortcodes(){
//slider for "Choose You" Slider
add_shortcode("lipstick_person", array($this,"shortcode_person_slider_caller"));
}
/*
* Calling Function to include scripts and then fire the actual shortcode function contained in separate .php file
*/
public function shortcode_person_slider_caller($atts, $content){
//register styles/scripts
$this->register_shortcode_requirements();
//run actual function for rendering
$content = shortcode_person_slider($atts);
return $content;
}
```
Then in the caller function the `shortcode_person_slider` is a function included in one of the require\_once loaded files.
The function is firing (tested with a var\_dump) in that function and it displays. Yet, the content is not displaying on the page (even though $content has all of the html markup).
Further, the script/style files are not being enqueued.
When testing, the `register_shortcode_requirements()` is firing, but each of the wp\_enqueue\_script hooks are not.
Any advice? Thank you!

As Rarst already noted, you answered your question. You are telling the software to load those scripts all the time. You need to control that process. Software is stupid. It can't decide when a good time is to load the code. SO...
>

Since you say the script should load only when a shortcode is used, go ahead and register your scripts but enqueue then in the shortcode handler, like [this from another question](https://wordpress.stackexchange.com/a/123549/21376):
```
function my_shortcode( $atts, $content = null ) {
extract(shortcode_atts(array(
'title' => '',
), $atts));
static $counter = 0;
echo $counter++;
wp_enqueue_script('wp-mediaelement');
}
add_shortcode('enq','my_shortcode');
```
Your script will load in the footer of the page, so make sure the Javascript can manage that.
As for your stylesheet,
1. You can load those in the footer of the page similarly to the
scripts. This is invalid markup but tends to work.
2. You can load the styles inline in the shortcode, which is a decent
option, maybe the best one.
3. You can have the javascript insert the styles dynamically
4. You can "pre-process" the shortcode, similarly to this (which is a
resource intensive solution):

Use `tag__not_in` parameter. You have to use tag ID for this parameter
```
$args = array(
'category_name' => $cat_name,
'tag' => $tag_name,
'post__not_in' => $sticky,
'tag__not_in' => array($tag_id_1, $tag_id_2)

Got it, it turns out...
1. The label for each radio button must be the field id / variable, in my example is 'radio\_buttons'
2. The IF statement for each radio button must refer to this same ID - **$radio\_buttons === 'radio\_option\_1'** & **$radio\_buttons === 'radio\_option\_2'**
My new code which works is...
```
<p>
<label for="<?php echo $this->get_field_id('text_area'); ?>">
<?php echo('Radio buttons'); ?>
</label><br>
<label for="<?php echo $this->get_field_id('radio_buttons'); ?>">
<?php _e('Option 1:'); ?>
<input class="" id="<?php echo $this->get_field_id('radio_option_1'); ?>" name="<?php echo $this->get_field_name('radio_buttons'); ?>" type="radio" value="radio_option_1" <?php if($radio_buttons === 'radio_option_1'){ echo 'checked="checked"'; } ?> />
</label><br>

</label>

<p>I've checked any threads here regarding this and did a debug test which worked, I'd like to understand why my own code doesn't work as it presents the same functionality explained in every possible thread created about this issue.</p>
<p>I'm trying to send AJAX request when clicking on a checkbox and do some work with MySQL.</p>
<p>Here are some details to understand the scope and what was done:</p>
<pre><code>var $ = jQuery;
$(function() {
$('table.table').on('click', '[name="term-id"]', function() {
var t = $(this),
id = t.val(),
checked = t.is(':checked');
checkCategory(id, checked);
});
});
function checkCategory(id, checked) {
$.ajax({
url: ajaxurl,
type: 'POST',
dataType: 'json',
data: {action: 'setAsyncCheckProduct', id: id, checked: checked},
success: function(response) {
alert(response);
},
error: function(errorThrown) {
alert(errorThrown);
}
})
}
</code></pre>
<p>This script is included in my plugin via:</p>
<pre><code>wp_enqueue_script('settings-manager', $this->pluginUrl . '/assets/js/SettingsManager.js');
</code></pre>
<p>In my main (abstract) plugin class (It is instantiated and is getting called, so I omit this code sample), but I add my async events assigned to admin_init:</p>
<pre><code>add_action('admin_init', [$this, 'assignAsyncEvents']);
</code></pre>
<p>In my concrete classes, I implement this method like:</p>
<pre><code>public function setAsyncCheckProduct()
{
var_dump($_REQUEST);
echo 123123123;
wp_die();
}
public function assignAsyncEvents()
{
add_action('wp_ajax_setAsyncCheckProduct', [$this, 'setAsyncCheckProduct']);
}
</code></pre>
<p>Which basically means:</p>
<blockquote>
<p>Send AJAX request to whatever is "ajaxurl" (which returns correct: /wp-admin/admin-ajax.php), action: setAsyncCheckProduct is sent along to the server, on the server, the assignAsyncEvents should be already done and a wp_ajax_MY_ACTION_NAME assigned.</p>
</blockquote>
<p>Why do I still get a 0 in response?</p>
<p>Thanks</p>
<p><strong>UPDATE</strong>
I've been manually putting debug output in admin-ajax.php just for the sake of curiosity.</p>
<pre><code>if ( is_user_logged_in() ) {

I've checked any threads here regarding this and did a debug test which worked, I'd like to understand why my own code doesn't work as it presents the same functionality explained in every possible thread created about this issue.
I'm trying to send AJAX request when clicking on a checkbox and do some work with MySQL.
Here are some details to understand the scope and what was done:
```
var $ = jQuery;
$(function() {
$('table.table').on('click', '[name="term-id"]', function() {
var t = $(this),
id = t.val(),
checked = t.is(':checked');
checkCategory(id, checked);
});
});
function checkCategory(id, checked) {
$.ajax({
url: ajaxurl,
type: 'POST',
dataType: 'json',
data: {action: 'setAsyncCheckProduct', id: id, checked: checked},
success: function(response) {
alert(response);
},
error: function(errorThrown) {
alert(errorThrown);
}
})
}
```
This script is included in my plugin via:
```
wp_enqueue_script('settings-manager', $this->pluginUrl . '/assets/js/SettingsManager.js');
```
In my main (abstract) plugin class (It is instantiated and is getting called, so I omit this code sample), but I add my async events assigned to admin\_init:
```
add_action('admin_init', [$this, 'assignAsyncEvents']);
```
In my concrete classes, I implement this method like:
```
public function setAsyncCheckProduct()
{
var_dump($_REQUEST);
echo 123123123;
wp_die();
}
public function assignAsyncEvents()
{
add_action('wp_ajax_setAsyncCheckProduct', [$this, 'setAsyncCheckProduct']);
}
```
Which basically means:
>
> Send AJAX request to whatever is "ajaxurl" (which returns correct: /wp-admin/admin-ajax.php), action: setAsyncCheckProduct is sent along to the server, on the server, the assignAsyncEvents should be already done and a wp\_ajax\_MY\_ACTION\_NAME assigned.
>
>
>
Why do I still get a 0 in response?
Thanks
**UPDATE**
I've been manually putting debug output in admin-ajax.php just for the sake of curiosity.
```
if ( is_user_logged_in() ) {
/**
* Fires authenticated AJAX actions for logged-in users.
*
* The dynamic portion of the hook name, `$_REQUEST['action']`,
* refers to the name of the AJAX action callback being fired.
*
* @since 2.1.0
*/
do_action( 'wp_ajax_' . $_REQUEST['action'] );
var_dump('wp_ajax_' . $_REQUEST['action']);
} else {
/**
* Fires non-authenticated AJAX actions for logged-out users.
*
* The dynamic portion of the hook name, `$_REQUEST['action']`,
* refers to the name of the AJAX action callback being fired.
*
* @since 2.8.0
*/
do_action( 'wp_ajax_nopriv_' . $_REQUEST['action'] );
}
// Default status
die( '0' );
```
This is the core functionality with my var\_dump added. My AJAX call GETS THERE and the output is CORRECT ACTION NAME defined in add\_action in my plugin files, thought nothing is returned from my action/it's not being called and I get to the default `die( '0' );`
Bummer. Don't know what to do further.

The problem is where you place the add\_action of your wp\_ajax\_\*
Try to put it at the start of everything, and ensuring that it is being loaded in a /wp-admin/ route.
Try your url: <http://xxx/wp-admin/admin-ajax.php?action=your_action> until it gives you something different than zero.

I am currently developing a one-page based layout with WordPress where the actual content is split up into separate pages in the backend, which are all knit together to a one-page layout in my front-page template file.
The WordPress menus allow for custom URLs which is probably the easiest way to cater a one-pager by referring to #hash-based links which lead to the corresponding divs.
However, I am looking for the probably cleanest solution to organise the menu and its anchors so that the actual editors/admins of a site can simply link to an actual page and have a custom walker translate that into a hash that leads to the right section on the frontend.
So far I would go with the slug of the single pages, let the wp\_query pick up the slug and add it as an ID to the wrapping div, e.g.
Page 1 called 'The about page' has a slug 'about-page', so the div then looks like

and type that slug as the hash URL in the menu editor.
Is there a simple walker or another solution that helps out in this case, i.e. turns links to pages into simple hashes? Or an even better practice?

Well, after some more intense research I finally found a viable solution that is clean and simple and works flawless so far.
Just put this into your functions.php to create a custom walker which turns classic permalinks into hashes (e.g. page.com/mypage to page.com/#mypage):
```
/* Custom nav walker */
class Single_Page_Walker extends Walker_Nav_Menu{
function start_el(&$output, $item, $depth = 0, $args = array(), $id = 0) {
global $wp_query;
$indent = ( $depth ) ? str_repeat( "\t", $depth ) : '';
$class_names = $value = '';
$classes = empty( $item->classes ) ? array() : (array) $item->classes;
$class_names = join( ' ', apply_filters( 'nav_menu_css_class', array_filter( $classes ), $item ) );
$class_names = ' class="'. esc_attr( $class_names ) . '"';
$output .= $indent . '<li id="menu-item-'. $item->ID . '"' . $value . $class_names .'>';
$attributes = ! empty( $item->attr_title ) ? ' title="' . esc_attr( $item->attr_title ) .'"' : '';
$attributes .= ! empty( $item->target ) ? ' target="' . esc_attr( $item->target ) .'"' : '';
$attributes .= ! empty( $item->xfn ) ? ' rel="' . esc_attr( $item->xfn ) .'"' : '';
if($item->object == 'page')
{
$varpost = get_post($item->object_id);
if(is_home()){
$attributes .= ' href="#' . $varpost->post_name . '"';
}else{
$attributes .= ' href="'.home_url().'/#' . $varpost->post_name . '"';
}
}
else
$attributes .= ! empty( $item->url ) ? ' href="' . esc_attr( $item->url ) .'"' : '';
$item_output = $args->before;
$item_output .= '<a'. $attributes .'>';
$item_output .= $args->link_before . apply_filters( 'the_title', $item->title, $item->ID );
$item_output .= $args->link_after;
$item_output .= '</a>';
$item_output .= $args->after;
$output .= apply_filters( 'walker_nav_menu_start_el', $item_output, $item, $depth, $args, $id );
}
}
```
Then, where you want your menu to appear, put the following code to call your menu (which you should have defined as a menu position before in your functions.php), and adjust the options to your liking, apart from the 'walker' part:
```
<?php
wp_nav_menu(array(
'theme_location' => 'onepage',
'echo' => true,
'container' => false,
'walker'=> new Single_Page_Walker,
'depth' => 1) );
?>
```
— that’s it already. Now you can fill up your menu in the backend without caring about hashes anymore :).

From code for post type and custom taxonomy, your CPT is `post_features` and taxonomy is `features`.
For single `post_features`, you need to have file named `single-post_features.php`. For archive, create file `taxonomy-features.php`.
See documentation for detail. <https://codex.wordpress.org/Post_Type_Templates>
**Example for single(single-post\_features.php):**
```
<?php get_header(); ?>
<?php
if ( have_posts() ) {
while ( have_posts() ) {
the_post();
the_title();
the_content();
} // end while
} // end if
?>
<?php get_footer(); ?>
```
**Example for Archive(taxonomy-features.php):**
```
<?php get_header(); ?>
<?php
if ( have_posts() ) {
the_archive_title( '<h1>', '</h1>' );
while ( have_posts() ) {
the_post();
the_title();
the_content();
} // end while
} // end if
?>
<?php get_footer(); ?>
```
**Note:** Please flush your permalink if you are getting 404 error.

In [WordPress 4.2](https://make.wordpress.org/core/2015/04/23/spinners-and-dismissible-admin-notices-in-4-2/) the `is-dismissible` class was introduced to allow notices to be dismissed.
This code is working to add the notice.
```
function prefix_deprecated_hook_admin_notice() {
if ( has_filter( 'prefix_filter' ) ) { ?>
<div class="updated notice is-dismissible">
<p><?php _e( 'Notice', 'my-text-domain' ); ?></p>
</div>
<?php }
}
add_action( 'admin_notices', 'prefix_deprecated_hook_admin_notice' );
```
I am able to dismiss the notice but I am unsure how I can save the state when the notice is dismissed with AJAX.

There's no need for a library, it's fairly straightforward to accomplish. If you are coding your own plugin (which it appears you are), then you can do this in a fairly lightweight way:
A slightly modified version of the notice, which checks if it's been dismissed before displaying, and stores the "type" of notice in the markup for access in javascript:
```
function prefix_deprecated_hook_admin_notice() {
if ( has_filter( 'prefix_filter' ) ) {
// Check if it's been dismissed...
if ( ! get_option('dismissed-prefix_deprecated', FALSE ) ) {
// Added the class "notice-my-class" so jQuery pick it up and pass via AJAX,
// and added "data-notice" attribute in order to track multiple / different notices
// multiple dismissible notice states ?>
<div class="updated notice notice-my-class is-dismissible" data-notice="prefix_deprecated">
<p><?php _e( 'Notice', 'my-text-domain' ); ?></p>
</div>
<?php }
}
}
add_action( 'admin_notices', 'prefix_deprecated_hook_admin_notice' );
```
And then, the following jQuery
```
// shorthand no-conflict safe document-ready function
jQuery(function($) {
// Hook into the "notice-my-class" class we added to the notice, so
// Only listen to YOUR notices being dismissed
$( document ).on( 'click', '.notice-my-class .notice-dismiss', function () {
// Read the "data-notice" information to track which notice
// is being dismissed and send it via AJAX
var type = $( this ).closest( '.notice-my-class' ).data( 'notice' );
// Make an AJAX call
// Since WP 2.8 ajaxurl is always defined in the admin header and points to admin-ajax.php
$.ajax( ajaxurl,
{
type: 'POST',
data: {
action: 'dismissed_notice_handler',
type: type,
}
} );
} );
});
```
In PHP, set up the AJAX hooks to capture the AJAX call:
```
add_action( 'wp_ajax_dismissed_notice_handler', 'ajax_notice_handler' );
/**
* AJAX handler to store the state of dismissible notices.
*/
function ajax_notice_handler() {
// Pick up the notice "type" - passed via jQuery (the "data-notice" attribute on the notice)
$type = self::request( 'type' );
// Store it in the options table
update_option( 'dismissed-' . $type, TRUE );
}
```
And that's it! No library needed - especially if you've already got PHP and javascript files loading.

<p>I search a lot that how can i re-size images that upload with meta field but i get nothing instead of <code>wp_get_image_editor</code>. I read from codex about it but nothing helpful so I search about this function and found these links</p>
<p><a href="http://bhoover.com/wp_image_editor-wordpress-image-editing-tutorial/" rel="nofollow">http://bhoover.com/wp_image_editor-wordpress-image-editing-tutorial/</a></p>
<p><a href="http://wpunknown.com/wp_image_editor/" rel="nofollow">http://wpunknown.com/wp_image_editor/</a></p>
<p>but it also not usefull for me.</p>
<p>I tried scripts from first link. First i upload an image from media and then create a page template and write this code in my template in while loop:</p>
<pre><code>if(have_posts()) :
while(have_posts()) :
the_post();
the_title();
// wp editor image script
$testing_img_src = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), 'full');
$img = wp_get_image_editor( $testing_img_src[0] );
if ( ! is_wp_error( $img ) ) {
$img->resize( 500, NULL, false );
$img->set_quality( 100 );
$img->stream();
}
endwhile;
</code></pre>
<p>When i fresh the page it gives me this kind of crap:</p>

<p>I also tried to add hard coded image path like:</p>
<pre><code>//$testing_img_src = ABSPATH.'wp-content/uploads/2015/06/colorful-background-31.jpg';
</code></pre>
<p>but it gives me same result. So please help me that how can i use <code>wp_get_image_editor()</code> so that my image resized or crop OR there is an other way for this.</p>
<p><strong><em>NOTE:</em></strong> I don't want to use <code>add_image_size()</code></p>

I search a lot that how can i re-size images that upload with meta field but i get nothing instead of `wp_get_image_editor`. I read from codex about it but nothing helpful so I search about this function and found these links
<http://bhoover.com/wp_image_editor-wordpress-image-editing-tutorial/>
<http://wpunknown.com/wp_image_editor/>
but it also not usefull for me.
I tried scripts from first link. First i upload an image from media and then create a page template and write this code in my template in while loop:
```
if(have_posts()) :
while(have_posts()) :
the_post();
the_title();
// wp editor image script
$testing_img_src = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), 'full');
$img = wp_get_image_editor( $testing_img_src[0] );
if ( ! is_wp_error( $img ) ) {
$img->resize( 500, NULL, false );
$img->set_quality( 100 );
$img->stream();
}
endwhile;
```
When i fresh the page it gives me this kind of crap:
```

I also tried to add hard coded image path like:
```
//$testing_img_src = ABSPATH.'wp-content/uploads/2015/06/colorful-background-31.jpg';
```
but it gives me same result. So please help me that how can i use `wp_get_image_editor()` so that my image resized or crop OR there is an other way for this.
***NOTE:*** I don't want to use `add_image_size()`
|
A possible solution:
--------------------
**Goal:** Don't use `add_image_size()` to show a custom sized image.
If you calculate the image without saving it, all requests will sum up to a huge page load due to repeated unnecessary processing time. So caching or saving the results should be an additional goal.
Add a **image-processor.php** in your template/plugin:
```
//Load your WordPress enviroment
$path = dirname(__FILE__);
$path = substr($path, 0, stripos($path, "wp-content") );
require( $path . "wp-load.php");
//TODO: filter and handle your $_GET params
$post_id = absint($_GET['post_id']);
$testing_img_url = wp_get_attachment_image_url(
get_post_thumbnail_id($post->ID), 'full'
);
if (!$testing_img_url)
$testing_img_url = 'http://domain.tld/path/to/defaul-image.jpg';
$img = wp_get_image_editor( $testing_img_url );
if ( ! is_wp_error( $img ) ) {
header('Content-type:'.finfo_file ($testing_img_url));
$img->resize( 500, NULL, false );
$img->set_quality( 100 );
$img->stream();
}
```
You can display the image in a loop now like this:
**Template**:
```
<img src="<?= get_template_directory_uri()?>/image-processor.php?post_id=<?= get_the_ID()?>">
```
**Plugin**:
```
<img src="<?= plugin_dir_path(__FILE__)?>image-processor.php?post_id=<?= get_the_ID()?>">
```
Possible improvements:
----------------------
* Caching/saving the processed images.
* Better error handling.

In a WordPress footer hooks are different for back-end(dashboard) and front-end.
In Dashboard use "`admin_footer`" hook.
In Front-end use "`wp_footer`" hook.

Set the constant `DISALLOW_FILE_MODS` to `TRUE` in your `wp-config.php`:
```
const DISALLOW_FILE_MODS = TRUE;
```
See [the Codex](https://codex.wordpress.org/Editing_wp-config.php#Disable_the_Plugin_and_Theme_Editor) for background information:
>
> Setting this constant also disables the Plugin and Theme editor (i.e. you don't need to set `DISALLOW_FILE_MODS` and `DISALLOW_FILE_EDIT`, as on its own `DISALLOW_FILE_MODS` will have the same effect).
>
>
>
It will also prevent installing or uninstalling plugins, themes and updating the WordPress core.
This will not affect the Git deployment.

<p>I'll admit, I'm not a PHP expert, nor am I familiar with all of the WordPress functions and hooks. I've been stuck on an issue, searching for help without much success, and I was hoping that someone could help point me in the right direction.</p>
<p>I have a form. The user selects a specialty, location, and distance (10 miles, 20, 50, etc). The results are queried from a custom post type and filtered to match the specialty. The posts have their latitude and longitude in the meta data but I am not sure how to bring this into the query. I want the posts to only show if their latitude/longitude is within proximity from the specified distance. I have the functionality written already to get their distance. The trouble I'm having is with the query and displaying the data properly.</p>
<p>Here are my current query arguments:</p>
<pre><code>$args = array(
'post_type' => 'team-members',
'posts_per_page' => -1,
'meta_query' => array(
array(
'key' => 'specialties',
'value' => $_GET['specialization'],
'compare' => 'LIKE'
)
)
);
$loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post();
</code></pre>
<p>This currently will display all the posts with the matching specialization, however, does not include anything involving the distance. So what I initially did was then set a conditional to check if the post was within the distance specified (don't worry about these variables, they are displaying the correct data):</p>
<pre><code>if ( $distance < $_GET['within'] ) {
</code></pre>
<p>The issue is that this condition is not factored into the query, and I am unable to sort by distance. Additionally, I have to set a counter in order to get a correct post "count", plus it just feels hacked together. I feel like there is a foundational error here, and I can't pinpoint it.</p>
<p>I hope this information was sufficient, and if you need anything clarified, please comment. I didn't want to overwhelmingly provide more than was necessary.</p>

I'll admit, I'm not a PHP expert, nor am I familiar with all of the WordPress functions and hooks. I've been stuck on an issue, searching for help without much success, and I was hoping that someone could help point me in the right direction.
I have a form. The user selects a specialty, location, and distance (10 miles, 20, 50, etc). The results are queried from a custom post type and filtered to match the specialty. The posts have their latitude and longitude in the meta data but I am not sure how to bring this into the query. I want the posts to only show if their latitude/longitude is within proximity from the specified distance. I have the functionality written already to get their distance. The trouble I'm having is with the query and displaying the data properly.
Here are my current query arguments:
```
$args = array(
'post_type' => 'team-members',
'posts_per_page' => -1,
'meta_query' => array(
array(
'key' => 'specialties',
'value' => $_GET['specialization'],
'compare' => 'LIKE'
)
)
);
$loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post();
```
This currently will display all the posts with the matching specialization, however, does not include anything involving the distance. So what I initially did was then set a conditional to check if the post was within the distance specified (don't worry about these variables, they are displaying the correct data):
```
if ( $distance < $_GET['within'] ) {
```
The issue is that this condition is not factored into the query, and I am unable to sort by distance. Additionally, I have to set a counter in order to get a correct post "count", plus it just feels hacked together. I feel like there is a foundational error here, and I can't pinpoint it.
I hope this information was sufficient, and if you need anything clarified, please comment. I didn't want to overwhelmingly provide more than was necessary.

here is the mysql query you can use to get the result having distance less then your value.
```
SELECT * , pm1.meta_value as latitude, pm2.meta_value as longitude ,
(((acos(sin(([latitude]*pi()/180)) *
sin((pm1.meta_value * pi()/180)) + cos(([latitude]*pi()/180)) *
cos((pm1.meta_value * pi()/180)) * cos((([longitude] - pm2.meta_value)*
pi()/180))))*180/pi())*60*1.1515
) as distance
FROM wp_posts p
JOIN wp_postmeta pm1 ON pm1.post_id = p.ID AND pm1.meta_key = 'latitude'
JOIN wp_postmeta pm2 ON pm2.post_id = p.ID AND pm2.meta_key = 'longitude'
WHERE ID = 98
having distance < $_GET['within']
```
It will return all the post with distance is less then your $\_GET['within'] value.

To display monthly archives arranged by year, you can use this code. It checks through each month if WordPress have any post in that month and create archive.
```
<?php
global $wpdb;
$limit = 0;
$year_prev = null;
$months = $wpdb->get_results( "SELECT DISTINCT MONTH( post_date ) AS month , YEAR( post_date ) AS year, COUNT( id ) as post_count FROM $wpdb->posts WHERE post_status = 'publish' and post_date <= now( ) and post_type = 'post' GROUP BY month , year ORDER BY post_date DESC" );
foreach( $months as $month ) :
$year_current = $month->year;
if ( $year_current != $year_prev ) {
if ( $year_prev != null ) { ?>
<?php } ?>
<h3><a href="<?php bloginfo('url') ?>/<?php echo $month->year; ?>/"><?php echo $month->year; ?></a></h3>
<?php } ?>
<li><a href="<?php bloginfo('url') ?>/<?php echo $month->year; ?>/<?php echo date("m", mktime(0, 0, 0, $month->month, 1, $month->year)) ?>"><span class="archive-month"><?php echo date_i18n("F", mktime(0, 0, 0, $month->month, 1, $month->year)) ?></span></a></li>
<?php $year_prev = $year_current;
if( ++$limit >= 18 ) { break; }
endforeach;
?>

I would want to allow certain user to edit only one page and it's subpages. How would this be possible? I tried the old Role Scoper, but it seems to have a lot of problems and bugs.
|
The first thing to do to implements such task is to be able to recognise which page an user can edit.
There are different ways to do it. It could be a user meta, some configuration value... For the sake of this answer, I will assume that a function lile this exists:
```
function wpse_user_can_edit( $user_id, $page_id ) {
$page = get_post( $page_id );
// let's find the topmost page in the hierarchy
while( $page && (int) $page->parent ) {
$page = get_post( $page->parent );
}
if ( ! $page ) {
return false;
}
// now $page is the top page in the hierarchy
// how to know if an user can edit it, it's up to you...
}
```
Now that we have a way to determine if an user can edit a page we just need to tell WordPress to use this function to check useer capability to edit a page.
That can be done via [`'map_meta_cap'`](https://developer.wordpress.org/reference/hooks/map_meta_cap/) filter.
Something like:
```
add_filter( 'map_meta_cap', function ( $caps, $cap, $user_id, $args ) {
$to_filter = [ 'edit_post', 'delete_post', 'edit_page', 'delete_page' ];
// If the capability being filtered isn't of our interest, just return current value
if ( ! in_array( $cap, $to_filter, true ) ) {
return $caps;
}
// First item in $args array should be page ID
if ( ! $args || empty( $args[0] ) || ! wpse_user_can_edit( $user_id, $args[0] ) ) {
// User is not allowed, let's tell that to WP
return [ 'do_not_allow' ];
}
// Otherwise just return current value
return $caps;
}, 10, 4 );
```
At this point, we need only a way to *connect* an user to one or more pages.
There might be different solutions depending on use case.
A flexible solution could be to add a dropdown of "root" pages (see [`wp_dropdown_pages`](https://developer.wordpress.org/reference/functions/wp_dropdown_pages/)) to the edit user admin screen, and save selected page(s) as user meta.
We could leverage [`'edit_user_profile'`](https://developer.wordpress.org/reference/hooks/edit_user_profile/) to add the pages dropdown field and [`'edit_user_profile_update'`](https://developer.wordpress.org/reference/hooks/edit_user_profile_update/) to store the selected value as user meta.
I am sure that in this website there's enough guidance on how to that in detail.
When page(s) are stored as user meta, the `wpse_user_can_edit()` function from above can be finished by checking if the page id is part of the user meta value.
Removing capability to edit the page, WordPress will do the rest: will remove any edit link from backend and frontend, will prevent direct access... and so on.

<p>I have a property website with a custom search form for minimum and maximum square feet.</p>
<p>A registered user executes a search with a min(i.e. 150 sqft) and max(i.e. 300 sqft) select option value. </p>
<p>I managed already to store inside cookies the min and max values. </p>
<p>Then the user is able to click on a "save this search" button. </p>
<p>I would like to save those values inside the database and show them on each user's profile page (that I already created). </p>
<p>When the user goes to its profile page I'd like to have a list of all the saved searches. </p>
<p>I hope this makes sense.</p>
<p>Ideally the custom user page would look like this:</p>
<p>Saved Search 1: 150sq ft - 300 sq ft</p>
<p>Saved Search 2: 500sq ft - 800 sq ft</p>
<p>...</p>
<p>Is this possible? How would I do this?</p>
<p>I'm quite new at customising WordPress templates, I would really appreciate any help.</p>

I have a property website with a custom search form for minimum and maximum square feet.
A registered user executes a search with a min(i.e. 150 sqft) and max(i.e. 300 sqft) select option value.
I managed already to store inside cookies the min and max values.
Then the user is able to click on a "save this search" button.
I would like to save those values inside the database and show them on each user's profile page (that I already created).
When the user goes to its profile page I'd like to have a list of all the saved searches.
I hope this makes sense.
Ideally the custom user page would look like this:
Saved Search 1: 150sq ft - 300 sq ft
Saved Search 2: 500sq ft - 800 sq ft
...
Is this possible? How would I do this?
I'm quite new at customising WordPress templates, I would really appreciate any help.

The first thing to do to implements such task is to be able to recognise which page an user can edit.
There are different ways to do it. It could be a user meta, some configuration value... For the sake of this answer, I will assume that a function lile this exists:
```
function wpse_user_can_edit( $user_id, $page_id ) {
$page = get_post( $page_id );
// let's find the topmost page in the hierarchy
while( $page && (int) $page->parent ) {
$page = get_post( $page->parent );
}
if ( ! $page ) {
return false;
}
// now $page is the top page in the hierarchy
// how to know if an user can edit it, it's up to you...
}
```
Now that we have a way to determine if an user can edit a page we just need to tell WordPress to use this function to check useer capability to edit a page.
That can be done via [`'map_meta_cap'`](https://developer.wordpress.org/reference/hooks/map_meta_cap/) filter.
Something like:
```
add_filter( 'map_meta_cap', function ( $caps, $cap, $user_id, $args ) {
$to_filter = [ 'edit_post', 'delete_post', 'edit_page', 'delete_page' ];
// If the capability being filtered isn't of our interest, just return current value
if ( ! in_array( $cap, $to_filter, true ) ) {
return $caps;
}
// First item in $args array should be page ID
if ( ! $args || empty( $args[0] ) || ! wpse_user_can_edit( $user_id, $args[0] ) ) {
// User is not allowed, let's tell that to WP
return [ 'do_not_allow' ];
}
// Otherwise just return current value
return $caps;
}, 10, 4 );
```
At this point, we need only a way to *connect* an user to one or more pages.
There might be different solutions depending on use case.
A flexible solution could be to add a dropdown of "root" pages (see [`wp_dropdown_pages`](https://developer.wordpress.org/reference/functions/wp_dropdown_pages/)) to the edit user admin screen, and save selected page(s) as user meta.
We could leverage [`'edit_user_profile'`](https://developer.wordpress.org/reference/hooks/edit_user_profile/) to add the pages dropdown field and [`'edit_user_profile_update'`](https://developer.wordpress.org/reference/hooks/edit_user_profile_update/) to store the selected value as user meta.
I am sure that in this website there's enough guidance on how to that in detail.
When page(s) are stored as user meta, the `wpse_user_can_edit()` function from above can be finished by checking if the page id is part of the user meta value.
Removing capability to edit the page, WordPress will do the rest: will remove any edit link from backend and frontend, will prevent direct access... and so on.

<p>From the <code>get_posts</code> docs I see it takes categories as a parameter.</p>
<p>However, is this an <code>AND</code> or an <code>OR</code>?</p>
<p>i.e. if you specify 2 categories do posts have to be in both to be returned?</p>
<p>If not, how do you specify an <code>AND</code> relation? I only want posts that match ALL categories.</p>

// now $page is the top page in the hierarchy
// how to know if an user can edit it, it's up to you...
}
```
Now that we have a way to determine if an user can edit a page we just need to tell WordPress to use this function to check useer capability to edit a page.
That can be done via [`'map_meta_cap'`](https://developer.wordpress.org/reference/hooks/map_meta_cap/) filter.
Something like:
```
add_filter( 'map_meta_cap', function ( $caps, $cap, $user_id, $args ) {
$to_filter = [ 'edit_post', 'delete_post', 'edit_page', 'delete_page' ];
// If the capability being filtered isn't of our interest, just return current value
if ( ! in_array( $cap, $to_filter, true ) ) {
return $caps;
}
// First item in $args array should be page ID
if ( ! $args || empty( $args[0] ) || ! wpse_user_can_edit( $user_id, $args[0] ) ) {
// User is not allowed, let's tell that to WP
return [ 'do_not_allow' ];
}
// Otherwise just return current value
return $caps;
}, 10, 4 );
```
At this point, we need only a way to *connect* an user to one or more pages.
There might be different solutions depending on use case.
A flexible solution could be to add a dropdown of "root" pages (see [`wp_dropdown_pages`](https://developer.wordpress.org/reference/functions/wp_dropdown_pages/)) to the edit user admin screen, and save selected page(s) as user meta.
We could leverage [`'edit_user_profile'`](https://developer.wordpress.org/reference/hooks/edit_user_profile/) to add the pages dropdown field and [`'edit_user_profile_update'`](https://developer.wordpress.org/reference/hooks/edit_user_profile_update/) to store the selected value as user meta.
I am sure that in this website there's enough guidance on how to that in detail.
When page(s) are stored as user meta, the `wpse_user_can_edit()` function from above can be finished by checking if the page id is part of the user meta value.
Removing capability to edit the page, WordPress will do the rest: will remove any edit link from backend and frontend, will prevent direct access... and so on.

The first thing to do to implements such task is to be able to recognise which page an user can edit.
There are different ways to do it. It could be a user meta, some configuration value... For the sake of this answer, I will assume that a function lile this exists:
```
function wpse_user_can_edit( $user_id, $page_id ) {
$page = get_post( $page_id );
// let's find the topmost page in the hierarchy
while( $page && (int) $page->parent ) {
$page = get_post( $page->parent );
}
if ( ! $page ) {
return false;
}
// now $page is the top page in the hierarchy
// how to know if an user can edit it, it's up to you...
}
```
Now that we have a way to determine if an user can edit a page we just need to tell WordPress to use this function to check useer capability to edit a page.
That can be done via [`'map_meta_cap'`](https://developer.wordpress.org/reference/hooks/map_meta_cap/) filter.
Something like:
```
add_filter( 'map_meta_cap', function ( $caps, $cap, $user_id, $args ) {
$to_filter = [ 'edit_post', 'delete_post', 'edit_page', 'delete_page' ];
// If the capability being filtered isn't of our interest, just return current value
if ( ! in_array( $cap, $to_filter, true ) ) {
return $caps;
}
// First item in $args array should be page ID
if ( ! $args || empty( $args[0] ) || ! wpse_user_can_edit( $user_id, $args[0] ) ) {
// User is not allowed, let's tell that to WP
return [ 'do_not_allow' ];
}
// Otherwise just return current value
return $caps;
}, 10, 4 );
```

<p>I have a WordPress install using a Comodo SSL certificate. I have the <a href="https://wordpress.org/plugins/wordpress-https/" rel="nofollow noreferrer">WordPress HTTPS plugin</a> installed and I'm using the AZ theme, and the admin is set to load over HTTPS. So far so good.</p>

Based on your question, I assume this is the plugin you are using to enable SSL: [WordPress HTTPS](https://wordpress.org/plugins/wordpress-https).
Considering that the plugin hasn't been updated in two years and their support questions haven't been resolved, there may be some compatibility issues with the latest version of WordPress (4.6 at the time of this writing). My recommendation to make sure your website's URL is running HTTPS everywhere.
THis can be done by executing the following SQL query in your database (*phpMyAdmin*):
```
UPDATE wp_options SET option_value = replace(option_value, 'HTTP_URL', 'HTTPS_URL') WHERE option_name = 'home' OR option_name = 'siteurl';
UPDATE wp_posts SET guid = replace(guid, 'HTTP_URL','HTTPS_URL');
UPDATE wp_posts SET post_content = replace(post_content, 'HTTP_URL', 'HTTPS_URL');
UPDATE wp_postmeta SET meta_value = replace(meta_value,'HTTP_URL','HTTPS_URL');
```
Replace the values with the following:
* `HTTP_URL` > your HTTP link (`http://some.site`)
* `HTTPS_URL` your HTTPS link (`https://some.site`)
This way, it prevents any mixed-content links from breaking things. I've also found a WordPress thread with a similar issue and not sure if you've already taken a look at it:

I built a custom post type "shop" with [Custom Post Type UI](https://wordpress.org/plugins/custom-post-type-ui/) plugin and added a field "address" (Google Map type) with [Advanced Custom Fields](https://wordpress.org/plugins/advanced-custom-fields/) plugin.
From the response of `WP_Query('post_type=shop');`, I got the following:
```
$shop = WP_Query('post_type=shop');
while($shop->have_post()) {
$shop->the_post();
$location = get_field('map-location');
if($location != null) {
echo $location['address'];
}
}
```
Here I got a list of addresses. How do I search with this "address"? Let's say user wants to search shop that is in "London", how can I achieve this?
Thanks.

**UPDATE**
Sample result of searching "15":
* 筲箕灣東大街15號B地下
* 九龍觀塘偉業街103號振邦工業大廈地鋪
* 九龍土瓜灣旭日街一號 瑞英工業大廈第一期A座地下
|
You need a [`meta_query`](https://codex.wordpress.org/Class_Reference/WP_Query#Custom_Field_Parameters) something like this:
```
$args = array(
'post_type' => 'shop',
'meta_query' => array(
array(
'key' => 'map-location',
'value' => 'London',
'compare' => 'LIKE' // the = operator might work depending on how your data is stored
),
)
);
```
Note: I am making some assumptions about how ACF stores data.

<p>Since WP3.5, <code>prepare()</code> accepts placeholders as a security measure, instead of just appending the argument to the query. Therefore, <code>$wpdb->prefix</code> needs to become a second parameter, called by <code>%s</code>:</p>
<pre><code>$count = $wpdb->get_var( $wpdb->prepare( "SELECT COUNT(id) FROM %s WHERE answer !=' '", $wpdb->prefix . "faq_questions" ) );
</code></pre>
<p>However, doing that returns the table name in quotes: </p>
<p><code>SELECT COUNT(id) FROM 'wp_faq_questions' WHERE answer !=' '</code> </p>

You can't, but it isn't broken. You are telling `prepare` to use a string. A string will be quoted. It isn't meant to generate MySQL syntax, which is what you are asking it to do. Your tablename is more a MySQL command or keyword than a string value. That isn't what `prepare` is for.
`prepare` is meant to operate on user supplied data. Your tablename is not-- well, shouldn't be-- user supplied data so you don't need to "prepare" it. It is unnecessary. Just construct the tablename in the SQL itself:
```
"SELECT COUNT(id) FROM ".$wpdb->prefix."faq_questions WHERE answer !=' '"
```

You will need to create `css` classes for a left and right column (you can use bootstrap if you like) after creating the classes try this
```
<div class="headlines" data-interval="<?php echo ($interval>0)?$interval*1000:'false'; ?>">

<?php

}
```
I'd like to do the same for search queries. Is it possible to add a meta query to the main query and have it only apply to a certain post type (i.e. `event`)? Pseudocode (I know this doesn't work, but to illustrate):

array(

```
|
In the case that the `start_date` custom field only exists for the `event` post type, this works:
```
$query->set( 'meta_query', array(
'relation' => 'OR',
array(
'key' => 'start_date',
'compare' => 'NOT EXISTS',
),
array(
'key' => 'start_date',

'compare' => '>=',
),
array(
'key' => 'end_date',
'value' => $today = date( 'Ymd' ),
'compare' => '>=',
),
) );
```
By comparing the `start_date` key to `NOT EXISTS`, the other post types are not filtered out. Obviously this is not an ideal solution, so I'm still curious if there are better ideas out there.

We have 2 WordPress sites in 2 different sub-domains like **test1.abc.com** and **test2.abc.com** . Both sites have **wp-require** plugin activated and only logged-in users can see the site. We want to make a system where if a user logged into one site, he should be auto-login into the other one.
**What I did:**
After some searching I know I need to use one database for both sites. So I have done these steps:
1. I have download the whole database of **test2.abc.com** site and change all prefix `wp_` to `wpmo_`, replace it in whole database and upload it into first site's database.
2. I added these 2 lines in `wp-config.php` of the second site, to define that second site should use first site's user table not its own one.
```
define('CUSTOM_USERMETA_TABLE', 'wp_usermeta');
define('CUSTOM_USER_TABLE', 'wp_users');
```
3. Now, the second site is using the first site's users and I am able to login to the second site by the user details of first site.
4. The next problem is cookies, so I added these lines in `wp-config` of both sites.
```
define('COOKIE_DOMAIN', '.abc.com');
define('COOKIEPATH', '/');
```
5. Now I logged in into **test1.abc.com** and when I go to **test2.abc.com** , it asks me to login. That means cookies are not passing from the first site to the second one.
Both subdomains are on same server and sharing same database user table.
I know it is a cookie issue and I have gone through many articles on that, but they all talk about sharing cookies between a domain and its subdomains. Here I am having 2 subdomains.

See [my answer on this exact problem](https://wordpress.stackexchange.com/a/183750/1685). Long story short, you also need to define `COOKIEHASH`, otherwise the login cookie names will be different for each site:
```
define( 'COOKIEHASH', 'randomhash' );
```
Make sure to change `randomhash` to a real hash, you can [grab one here](http://md5.my-addr.com/online_random_md5_hash_generator-and-md5_random_hash.php).

<p>I have static front page for my WP installation set from <code>settings > reading</code>. Then I have added a URL endpoint using.</p>
<pre><code>add_rewrite_endpoint('foo', EP_ALL);
</code></pre>
<p>So, the front page should be accessible via</p>
<pre><code>http://example.com/
http://example.com/foo
http://example.com/foo/bar
</code></pre>
<p>For #1 Everything works fine but for #2 and #3 default <code>home.php</code> is shown instead of static home page. Tested locally in both single and multisite installation.</p>
<p>Is it a desired behavior or I hit something unusual? More importantly how can I make WP to show the static homepage in the given condition?</p>
<h2>Solution</h2>
<p>I was already hooking into <code>parse_request</code> to process part of code if <code>foo</code> exists. so, as per @gmazzap's solution. I only need to unset it afterwards. No need for extra hooked function is needed to bypass the bug.</p>
<pre><code>add_action('parse_request', function(&wp){
$key = 'foo';
if (!array_key_exists( $key, $wp->query_vars ) ) {
return;
}
// do things when foo exists
// we no longer need 'foo'
unset($wp->query_vars[$key]);
});
</code></pre>

I have static front page for my WP installation set from `settings > reading`. Then I have added a URL endpoint using.
```
add_rewrite_endpoint('foo', EP_ALL);
```
So, the front page should be accessible via
```
http://example.com/
http://example.com/foo
http://example.com/foo/bar
```
For #1 Everything works fine but for #2 and #3 default `home.php` is shown instead of static home page. Tested locally in both single and multisite installation.
Is it a desired behavior or I hit something unusual? More importantly how can I make WP to show the static homepage in the given condition?
Solution
--------
I was already hooking into `parse_request` to process part of code if `foo` exists. so, as per @gmazzap's solution. I only need to unset it afterwards. No need for extra hooked function is needed to bypass the bug.
```
add_action('parse_request', function(&wp){
$key = 'foo';
if (!array_key_exists( $key, $wp->query_vars ) ) {
return;
}
// do things when foo exists
// we no longer need 'foo'
unset($wp->query_vars[$key]);
});
```

See [my answer on this exact problem](https://wordpress.stackexchange.com/a/183750/1685). Long story short, you also need to define `COOKIEHASH`, otherwise the login cookie names will be different for each site:
```
define( 'COOKIEHASH', 'randomhash' );
```
Make sure to change `randomhash` to a real hash, you can [grab one here](http://md5.my-addr.com/online_random_md5_hash_generator-and-md5_random_hash.php).

I have created a theme for one of our clients using bootstrap framework!
When i was working on it on Localhost it works Correctly, but when I Uploaded it doesn't work. When I Activate it from Appearance I Saw A blank white Page; Also when I Try to Post a new Comment, post, page or custom post type.
Is there any Help for this Problem?

This answer will be long, but can be helpful in some way.
First of all, detect why you're getting this error:
===================================================
Majority of the time when you see a **Wordpress' White Screen of Death**, it means that you **exhausted the memory limit** of your server settings.
This could be **caused by a plugin** that you may be using that is not functioning properly.
It could also be caused by a **poorly coded theme** that you are using - usually free themes download on the web.
It could also mean that there is an **issue with your web hosting server**.
Since the problem can be caused by any number of things, it may require a lot of troubleshooting.
Detect if the problem occur in other Wordpress websites:
========================================================
If you have multiple sites, then the first thing you should do is to make sure that the white screen of death is happening across the board or just on this one domain.
If the issue is with all of your sites, then it is a strong indicator that your web hosting provider is having some issues.
However, if the issue is only with one of your sites, then this could be an issue with a plugin or theme that you are running. If the issue is only happening with a single post or page, then you know it is definitely a problem with your specific site.
If possible, increase the Memory Limit:
=======================================
Usually this issue happens because your memory is being exhausted.
If increasing the memory limit did not help, or if you have a high memory limit like 256M or 512M, then you need to start troubleshooting. In our experience of troubleshooting this issue, we have always found that the issue is either with a specific plugin or a theme. Go ahead and disable all the plugins.
If this fixes the issue, then enable one plugin at a time to get to the bottom of the issue.
Try to replace Theme with a Default Theme and see if the problem persists:
==========================================================================
If the plugin troubleshooting doesn’t fix the issue, then you should try **replacing your current theme with a default twenty ten theme**.
The best way to do this is by backing up your theme folder. Then deleting the theme. WordPress will automatically fall back to the default theme.
Alternatively, you can go in your phpMyAdmin and update the database tables in wp\_options table. The following table names would have to be updated:
`template, stylesheet, and current_theme`. Change the value to twentyeleven.
If this fixes the issue, then you should look at your theme’s `functions.php` file.
If there are extra spaces at the bottom, then you should consider fixing it.
If you are using a poorly coded function in your theme’s `functions.php` file, then it can cause this as well.
Debug your code:
================
If none of the above fixes it, then you should try to re-install a **fresh copy of WordPress**. While it is unlikely, but it is always possible that a core file may have been corrupted.
You can also use the WordPress debug function to see what type of errors are being outputted. Add the following code in your wp-config.php file.
```
define( 'WP_DEBUG', true);
```
Once you add this, the blank screen will now have errors, warnings, and notices generated by PHP. These may be able to help you determine the root cause of the problem.
Make sure you're running on a Linux server:
===========================================
Wordpress usually don't work well on servers running Windows - so make sure you're using a server running Linux (this can be checked with your hosting company).

Running a no limit query is very likely the cause of your memory issues. So you might want to change your query.
If still you need to do this way, you can use the `fields` option, it returns post IDs only and will save a lot of memory usage - example below:
```
$your_query = get_posts(
array(
'posts_per_page' => -1,
'post_type' => 'post',
'fields' => 'ids',
)
);
```

Just a few days ago I've started working on my new wordpress based website.
I have a plugin which provides a Cars Database. I want to auto-fill my custom fields and taxonomies by taking info from this plugin.
So, I've created a custom function in functions.php. I put an ID from car's database plugin and my function autofills my fields when I PUBLISH or UPDATE the post (wp\_insert\_post). Everything seems to be working fine but...

What does this function do? It simply gets 3-4 different car marks from $cardet['marks'] and implodes it. This is required only for taxonomies.
**So, after I click publish or update the post:**
This is OK, this is how it looks like in "post edit" page. Created 3 different terms.

The second parameter to [`wp_set_object_terms()`](https://codex.wordpress.org/Function_Reference/wp_set_object_terms) takes an array, integer, or string.
>
> (*array/int/string*)
> (*required*) The slug or id of the term (such as category or tag

You create an array (`$cardet["marks"]`) but then `implode()` it. When you `implode()` it you turn that array into a comma separated string, which `wp_set_object_terms()` interprets as a single value. `wp_set_object_terms()` will not break the string on commas and create multiple terms for you, but the solution is simple as you've added a step that is breaking things. Remove that step and pass the array to `wp_set_object_terms()`.
```
if ( isset( $cardet['marks'] ) )
wp_set_object_terms( $post_id, $cardet["marks"], 'mark' );
```
There is sample code in the Codex doing exactly this, but with IDs:
```
// An array of IDs of categories we want this post to have.
$cat_ids = array( 6, 8 );
/*
* If this was coming from the database or another source, we would need to make sure
* these where integers:
$cat_ids = array_map( 'intval', $cat_ids );
$cat_ids = array_unique( $cat_ids );
*/
$term_taxonomy_ids = wp_set_object_terms( 42, $cat_ids, 'category' );
```
If `$cardet["marks"]` is user supplied data please [sanitize](https://codex.wordpress.org/Validating_Sanitizing_and_Escaping_User_Data) it before using it.

Does anyone have a logical solution for this?
|
For this situation, I create a custom page template, say `tpl-archive-page.php`.
For example using [Advanced Custom Fields](http://www.advancedcustomfields.com/) and the [Post Type Selector Field](https://github.com/TimPerry/acf-post-type-selector)(\*) the user can choose a post type to connect to.
```
<?php
/**
* Template Name: CPT Archive Page
*/
get_header();
while (have_posts()) :
the_post();
get_template_part('content', 'page');
$archive_query_post_type = get_post_meta(get_queried_object_id(), 'cpt_archive_query_post_type', true);
if( $archive_query_post_type && is_string($archive_query_post_type) ) {
$args = array(
'post_type' => $archive_query_post_type,
'posts_per_page'=> -1,
'orderby' => 'title',
);
$archive_query = new WP_Query( $args );
if ( $archive_query->have_posts() ) {
while ( $archive_query->have_posts() ) {
$archive_query->the_post();
get_template_part('content', get_post_type() );
}
}
wp_reset_postdata();
}
endwhile;
get_footer();
```
The `has_archive` option when registering the custom post type must be set to `false`.

<p>I already created a custom post type with post-format support declared.</p>
<pre><code>register_post_type('portfolio', array(
'labels' => array(
'name' => __('Portfolio', "xxx"),
'singular_name' => __('Portfolio', "xxx")
),
'public' => true,
'menu_position' => 5,
'rewrite' => array('slug' => 'portfolio'),
'supports' => array( 'title', 'editor', 'thumbnail', 'excerpt', 'comments', 'revisions', 'custom-fields', 'post-formats' )
)
);
</code></pre>
<p>However, when I go to Wordpress Export tool and try to export posts under this custom post type, I checked the exported xml file and saw that it doesn't export post-format value of posts.</p>
<p>Is there any solution for this?</p>

After spending time debugging export.php, I found that we have to register post\_format taxonomy for our custom post type.
```
register_taxonomy( 'post_format', 'portfolio', array(
'public' => true,
'hierarchical' => false,
'labels' => array(
'name' => _x( 'Format', 'post format' ),
'singular_name' => _x( 'Format', 'post format' ),
),
'query_var' => true,
'rewrite' => $rewrite['post_format'],
'show_ui' => false,
'_builtin' => true,
'show_in_nav_menus' => current_theme_supports( 'post-formats' ),
) );
```
Easy as that!

Paste this in your `functions.php`of the active Theme or leave it in a custom plugin. Replace `your-cpt` string.
```
/**
* Filter the feed, exclude specific custom post type
*
* @param WP_Query object $query
* @return void
*/
function wpse_191804_pre_get_posts( $query )
{
// only for feeds
if( !$query->is_feed || !$query->is_main_query() )
return query;
$exclude = 'your-cpt';
$post_types = $query->get('post_type');
if (($key = array_search($exclude, $post_types)) !== false)
unset($post_types[$key]);
$query->set( 'post_type', $post_types );
return $query;
}
add_action( 'pre_get_posts', 'wpse_191804_pre_get_posts' );

[If you look at WordPress' available query variables](https://codex.wordpress.org/WordPress_Query_Vars#Query_variables), you will notice `post_type`. You will need to add that to your URL:
```
$terms = get_the_terms( $post->ID , 'category' );
foreach ( $terms as $term ) {
$term_link = get_term_link( $term, 'category' );
if( is_wp_error( $term_link ) )
continue;
$term_link = add_query_arg(
array(
'post_type' => $post->post_type
),
$term_link
);
echo '<a href="' . $term_link . '">' . $term->name . '</a>';
}

I have a blog in WordPress. I have multiple categories. I want to use a specific layout for all posts under a category and all of its sub categories.
**Example :** My categories organized as bellow.
1. Guide(parent category)
1.1 Electical
1.1.1 TV
1.1.2 Radio
1.2 Plumbing
1.3 Home Repair
1.3.1 Kitchen
1.3.2 Bathroom

You can do that with `single_template` filter. First you will need to check if a post belongs to a top level category. So here is the function.
```
// custom single template for specific category
function wpse_custom_category_single_template( $single_template ) {
global $post;
// get all categories of current post
$categories = get_the_category( $post->ID );
$top_categories = array();
// get top level categories
foreach( $categories as $cat ) {
if ( $cat->parent != 0 ) {
$top_categories[] = $cat->parent;
} else {
$top_categories[] = $cat->term_id;
}
}
// check if specific category exists in array
if ( in_array( '8', $top_categories ) ) {
if ( file_exists( get_template_directory() . '/single-custom.php' ) ) return get_template_directory() . '/single-custom.php';
}
return $single_template;
}
add_filter( 'single_template', 'wpse_custom_category_single_template' );
```
In similar situation usually people check for parent category with `$categories[0]->category_parent;`, which is right but only works if you have assigned one category to each post. If you have 2 and more categories then this solution will always work.

Note that the `posts_orderby` filter is not available for `get_posts()` where `suppress_filters` is `true` by default.
You can use `WP_Query` instead:
```
$args = [
'posts_per_page' => 1,
'orderby' => 'rand',
'post_type' => 'listing',
'ignore_sticky_posts' => true,
];
add_filter( 'posts_orderby', 'force_random_day_seed' );
$q = new WP_Query( $args );
remove_filter( 'posts_orderby', 'force_random_day_seed' );
if( $q->have_posts() )
{
while( $q->have_posts() )
{
$q->the_post();
the_title();
}
wp_reset_postdata();
}
else
{
_e( 'Sorry no posts found!' );
}
```
It's also possible to skip your `posts_orderby` filter callback and just use [transients](https://codex.wordpress.org/Transients_API) to store the results for 24 hours.

**UPDATE**:
The hook is working with "classic" Wordpress filter (like `post__in`), so it's probably a Posts2Posts issue. I'm still looking for suggestions if someone has any idea.
**ORIGINAL POST**
I'm trying to get all posts displayed by issue number in archive pages. Issues are a custom post type (linked with post2post, which is why I use `parse_query` instead of `pre_get_post`)
```
<?php
function categories_by_issue ($query) {
if (! $query->is_category() || ! $query->is_main_query()) return;
$query->set( 'connected_type', 'issue_to_posts');
$query->set( 'connected_items', 71); // 71 needs to be dynamic
$query->set( 'nopaging', true);
}
add_action('parse_query', 'categories_by_issue');
?>
```
This action hook **works fine**! Problem is: I need to get the issue ID with another query. (ID and issue number are of course different, my '#3' issue has '71' ID)
I tried to add a `WP_Query` in my hook, which basically break the whole thing. I can get my issue number, but the main query finally shows all posts.
```
<?php
function categories_by_issue ($query) {
if (! $query->is_category() || ! $query->is_main_query()) return;
$issues = new WP_Query ( /* ... */);
$issue_id = $issues->get_posts()[0]->ID;
var_dump($issue_id); // -> 71 : My ID is correct
$query->set( 'connected_type', 'issue_to_posts');
$query->set( 'connected_items', $issue_id);
$query->set( 'nopaging', true);
}
add_action('parse_query', 'categories_by_issue');
?>
```
Is there a way I could request some information in my hook, ideally without involving direct SQL request?

I couldn't solve this issue but found a workaround : I get my issue ID on parse\_request hook
and use it in parse\_query (I created a class with an $issue\_id var, but global variable should be fine too).
Still don't know why you can't use WP\_Query directly in parse\_query, but I opened ticket on Posts2Posts github : <https://github.com/scribu/wp-posts-to-posts/issues/483>

<h2>Summary</h2>
<p>Because of a bug in WP Core, sending <a href="https://en.wikipedia.org/wiki/MIME">multipart</a> emails (html/text) with <a href="https://codex.wordpress.org/Function_Reference/wp_mail">wp_mail()</a> (to reduce chance of emails ending up in spam folders) will <em>ironically</em> result with your domain being blocked by Hotmail (and other Microsoft emails). </p>
<p>This is a complex problem that I'll aim to break down in great detail in an attempt to help someone find a workable solution which may eventually be implemented in core. </p>
<p><strong>It's going to be a rewarding read. Let's begin...</strong></p>
<h2>The bug</h2>
<p>The most common advice to avoid having your newsletter emails ending up in spam folders is to send multipart messages.</p>
<p>Multi-part (mime) refers to sending both an HTML and TEXT part of an email message in a single email. When a client receives a multipart message, it accepts the HTML version if it can render HTML, otherwise it presents the plain text version. </p>
<p>This is proven to work. When sending to gmail, all our emails landed in spam folders until we changed the messages to multipart when they came through to main inbox. Great stuff. </p>
<p>Now, when sending multipart messages via wp_mail(), it outputs the Content Type (multipart/*) twice, once with boundary (if customly set) and once without. This behaviour results with the email being displayed as a raw message and not multipart on some emails, including <strong>all</strong> Microsoft (Hotmail, Outlook, etc...)</p>
<p>Microsoft will flag this message as junk, and the few messages that comes through will be flagged manually by the recipient. <em>Unfortunately</em>, Microsoft emails addresses are widely used. 40% of our subscribers use it. </p>
<p>This is confirmed by Microsoft via an email exchange we had recently.</p>
<p>The flagging of the messages will result with the domain being completely <strong>blocked</strong>. This means that message will not be sent to spam folder, <strong>they will not even be delivered</strong> to the recipient at all. </p>
<p>We have had our main domain blocked 3 times so far. </p>
<p>Because this is a bug in the WP core, <strong>every</strong> domain that sends multipart messages are being blocked. The problem is that most webmasters do not know why. I have confirmed this when doing my research and seeing other users discussing this on forums etc. It requires delving into the raw code and having a good knowledge of how these type of email messages work, which we are going on to next...</p>
<h2>Let's break it down into code</h2>
<p>Create a hotmail/outlook account. Then, run the following code:</p>
<pre><code>// Set $to to an hotmail.com or outlook.com email
$to = "[email protected]";
$subject = 'wp_mail testing multipart';
$message = '------=_Part_18243133_1346573420.1408991447668
Content-Type: text/plain; charset=UTF-8
Hello world! This is plain text...
------=_Part_18243133_1346573420.1408991447668
Content-Type: text/html; charset=UTF-8
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
</head>
<body>
<p>Hello World! This is HTML...</p>
</body>
</html>
------=_Part_18243133_1346573420.1408991447668--';
$headers = "MIME-Version: 1.0\r\n";
$headers .= "From: Foo <[email protected]>\r\n";
$headers .= 'Content-Type: multipart/alternative;boundary="----=_Part_18243133_1346573420.1408991447668"';
// send email
wp_mail( $to, $subject, $message, $headers );
</code></pre>
<p>And if you want to change the <a href="http://codex.wordpress.org/Plugin_API/Filter_Reference/wp_mail_content_type">default content type</a>, use: </p>
<pre><code>add_filter( 'wp_mail_content_type', 'set_content_type' );
function set_content_type( $content_type ) {
return 'multipart/alternative';
}
</code></pre>
<p>This will send a multipart message. </p>
<p>So if you check the full raw source of the message, you'll notice that the content type is added twice, once without boundary: </p>
<pre><code>MIME-Version: 1.0
Content-Type: multipart/alternative;
boundary="====f230673f9d7c359a81ffebccb88e5d61=="
MIME-Version: 1.0
Content-Type: multipart/alternative; charset=
</code></pre>
<p>That's the issue. </p>
<p>The source of the problem lies in <code>pluggable.php</code> - if we look somewhere here: </p>
<pre><code>// Set Content-Type and charset
// If we don't have a content-type from the input headers
if ( !isset( $content_type ) )
$content_type = 'text/plain';
/**
* Filter the wp_mail() content type.
*
* @since 2.3.0
*
* @param string $content_type Default wp_mail() content type.
*/
$content_type = apply_filters( 'wp_mail_content_type', $content_type );
$phpmailer->ContentType = $content_type;
// Set whether it's plaintext, depending on $content_type
if ( 'text/html' == $content_type )
$phpmailer->IsHTML( true );
// If we don't have a charset from the input headers
if ( !isset( $charset ) )
$charset = get_bloginfo( 'charset' );
// Set the content-type and charset
/**
* Filter the default wp_mail() charset.
*
* @since 2.3.0
*
* @param string $charset Default email charset.
*/
$phpmailer->CharSet = apply_filters( 'wp_mail_charset', $charset );
// Set custom headers
if ( !empty( $headers ) ) {
foreach( (array) $headers as $name => $content ) {
$phpmailer->AddCustomHeader( sprintf( '%1$s: %2$s', $name, $content ) );
}
if ( false !== stripos( $content_type, 'multipart' ) && ! empty($boundary) )
$phpmailer->AddCustomHeader( sprintf( "Content-Type: %s;\n\t boundary=\"%s\"", $content_type, $boundary ) );
}
if ( !empty( $attachments ) ) {
foreach ( $attachments as $attachment ) {
try {
$phpmailer->AddAttachment($attachment);
} catch ( phpmailerException $e ) {
continue;
}
}
}
</code></pre>
<h2>Potential solutions</h2>
<p>So you are wondering, <strong>why have you not reported this at <a href="https://core.trac.wordpress.org/">trac</a>?</strong> I <a href="https://core.trac.wordpress.org/ticket/31653">already have</a>. To my great surprise, a <a href="https://core.trac.wordpress.org/ticket/15448">different ticket</a> was created 5 years ago outlining the same problem. </p>
<p>Let's face it, it's been a half decade. In internet years, that is more like 30. The issue has clearly been abandoned and basically will never be fixed (...unless if we resolve it here).</p>
<p>I found a great <a href="https://wordpress.org/support/topic/using-wp_mail-with-php-generated-attachments">thread here</a> offering a solution, but while his solution works, it breaks emails that do not have custom <code>$headers</code> set.</p>
<p>That's where we crash every time. Either the multipart version work fine, and normal unset <code>$headers</code> messages don't, or vise verse. </p>
<p>The solution we came up with was: </p>
<pre><code>if ( false !== stripos( $content_type, 'multipart' ) && ! empty($boundary) ) {
$phpmailer->ContentType = $content_type . "; boundary=" . $boundary;
}
else {
$content_type = apply_filters( 'wp_mail_content_type', $content_type );
$phpmailer->ContentType = $content_type;
// Set whether it's plaintext, depending on $content_type
if ( 'text/html' == $content_type )
$phpmailer->IsHTML( true );
// If we don't have a charset from the input headers
if ( !isset( $charset ) )
$charset = get_bloginfo( 'charset' );
}
// Set the content-type and charset
/**
* Filter the default wp_mail() charset.
*
* @since 2.3.0
*
* @param string $charset Default email charset.
*/
$phpmailer->CharSet = apply_filters( 'wp_mail_charset', $charset );
// Set custom headers
if ( !empty( $headers ) ) {
foreach( (array) $headers as $name => $content ) {
$phpmailer->AddCustomHeader( sprintf( '%1$s: %2$s', $name, $content ) );
}
}
</code></pre>
<p>Yes, I know, editing core files are taboo, sit back down... this was a desperate fix and a poor attempt to provide a fix for core. </p>
<p>The problem with our fix is that default emails like new registrations, comment, password reset etc will be delivered as blank messages. So we have a working wp_mail() script that will send multipart messages but nothing else. </p>
<h2>What to do</h2>
<p>The aim here is to find a way to send both normal (plain text) and multipart messages <strong>using the core wp_mail() function</strong> (not a custom sendmail function). </p>
<p>When attempting to solve this, the main problem you will encounter is the amount of time that you'll spend on sending dummy messages, checking if they're received and basically opening a box of aspirin and cursing at Microsoft because you are used to their IE issues while the gremlin here is unfortunately WordPress. </p>
<h2>Update</h2>
<p>The solution posted by @bonger allows <code>$message</code> to be an array containing content-type keyed alternates. I have confirmed that it works in all scenarios.</p>
<p>We will allow this question to remain open until bounty runs out to raise awareness about the problem, <strong>maybe to a level where it will be fixed in core.</strong> Feel free to post an alternative solution where <code>$message</code> can be a string. </p>

"text": "<p><strong>TLDR</strong>, the simple solution is:</p>\n<pre><code>add_action('phpmailer_init','wp_mail_set_text_body');\nfunction wp_mail_set_text_body($phpmailer) {\n if (empty($phpmailer->AltBody)) {$phpmailer->AltBody = wp_strip_all_tags($phpmailer->Body);}\n}\n</code></pre>\n<p>Then you don't need to set the headers explicitly at all, the header boundaries are set correctly for you.</p>\n<p>Read on to for a detailed explanation as to why...</p>\n<p>This is not really a WordPress bug at all, it is a <code>phpmailer</code> one in not allowing for custom headers... if you look at <code>class-phpmailer.php</code>:</p>\n<pre><code>public function getMailMIME()\n{\n $result = '';\n $ismultipart = true;\n switch ($this->message_type) {\n case 'inline':\n $result .= $this->headerLine('Content-Type', 'multipart/related;');\n $result .= $this->textLine("\\tboundary=\\"" . $this->boundary[1] . '"');\n break;\n case 'attach':\n case 'inline_attach':\n case 'alt_attach':\n case 'alt_inline_attach':\n $result .= $this->headerLine('Content-Type', 'multipart/mixed;');\n $result .= $this->textLine("\\tboundary=\\"" . $this->boundary[1] . '"');\n break;\n case 'alt':\n case 'alt_inline':\n $result .= $this->headerLine('Content-Type', 'multipart/alternative;');\n $result .= $this->textLine("\\tboundary=\\"" . $this->boundary[1] . '"');\n break;\n default:\n // Catches case 'plain': and case '':\n $result .= $this->textLine('Content-Type: ' . $this->ContentType . '; charset=' . $this->CharSet);\n $ismultipart = false;\n break;\n }\n</code></pre>\n<p>You can see the offending default case is what is outputting the extra header line with charset and no boundary. Setting the content type by filter does not solve this by itself only because the <code>alt</code> case here is set on <code>message_type</code> by checking <code>AltBody</code> is not empty rather than the content type.</p>\n<pre><code>protected function setMessageType()\n{\n $type = array();\n if ($this->alternativeExists()) {\n $type[] = 'alt';\n }\n if ($this->inlineImageExists()) {\n $type[] = 'inline';\n }\n if ($this->attachmentExists()) {\n $type[] = 'attach';\n }\n $this->message_type = implode('_', $type);\n if ($this->message_type == '') {\n $this->message_type = 'plain';\n }\n}\n\npublic function alternativeExists()\n{\n return !empty($this->AltBody);\n}\n</code></pre>\n<p>In the end what this means is as soon as you attach a file or inline image, or set the <code>AltBody</code>, the offending bug should be bypassed. It also means there is no need to explicitly set the content type because as soon as there is an <code>AltBody</code> it is set to <code>multipart/alternative</code> by <code>phpmailer</code>.</p>\n<p>So the simple answer is:</p>\n<pre><code>add_action('phpmailer_init','wp_mail_set_text_body');\nfunction wp_mail_set_text_body($phpmailer) {\n if (empty($phpmailer->AltBody)) {$phpmailer->AltBody = wp_strip_all_tags($phpmailer->Body);}\n}\n</code></pre>\n<p>Then you don't need to set the headers explicitly, you can simply do:</p>\n<pre><code> $message ='<html>\n <head>\n <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />\n </head>\n <body>\n <p>Hello World! This is HTML...</p> \n </body>\n </html>';\n\n wp_mail($to,$subject,$message);\n</code></pre>\n<p>Unforunately many of the functions and properties in the <code>phpmailer</code> class are protected, if not for that a valid alternative would be to simply check and override the <code>MIMEHeaders</code> property via the <code>phpmailer_init</code> hook before sending.</p>\n"

Summary
-------
Because of a bug in WP Core, sending [multipart](https://en.wikipedia.org/wiki/MIME) emails (html/text) with [wp\_mail()](https://codex.wordpress.org/Function_Reference/wp_mail) (to reduce chance of emails ending up in spam folders) will *ironically* result with your domain being blocked by Hotmail (and other Microsoft emails).
This is a complex problem that I'll aim to break down in great detail in an attempt to help someone find a workable solution which may eventually be implemented in core.
**It's going to be a rewarding read. Let's begin...**
The bug
-------
The most common advice to avoid having your newsletter emails ending up in spam folders is to send multipart messages.
Multi-part (mime) refers to sending both an HTML and TEXT part of an email message in a single email. When a client receives a multipart message, it accepts the HTML version if it can render HTML, otherwise it presents the plain text version.
This is proven to work. When sending to gmail, all our emails landed in spam folders until we changed the messages to multipart when they came through to main inbox. Great stuff.
Now, when sending multipart messages via wp\_mail(), it outputs the Content Type (multipart/\*) twice, once with boundary (if customly set) and once without. This behaviour results with the email being displayed as a raw message and not multipart on some emails, including **all** Microsoft (Hotmail, Outlook, etc...)
Microsoft will flag this message as junk, and the few messages that comes through will be flagged manually by the recipient. *Unfortunately*, Microsoft emails addresses are widely used. 40% of our subscribers use it.
This is confirmed by Microsoft via an email exchange we had recently.
The flagging of the messages will result with the domain being completely **blocked**. This means that message will not be sent to spam folder, **they will not even be delivered** to the recipient at all.
We have had our main domain blocked 3 times so far.
Because this is a bug in the WP core, **every** domain that sends multipart messages are being blocked. The problem is that most webmasters do not know why. I have confirmed this when doing my research and seeing other users discussing this on forums etc. It requires delving into the raw code and having a good knowledge of how these type of email messages work, which we are going on to next...
Let's break it down into code
-----------------------------
Create a hotmail/outlook account. Then, run the following code:
```
// Set $to to an hotmail.com or outlook.com email
$to = "[email protected]";
$subject = 'wp_mail testing multipart';
$message = '------=_Part_18243133_1346573420.1408991447668
Content-Type: text/plain; charset=UTF-8
Hello world! This is plain text...
------=_Part_18243133_1346573420.1408991447668
Content-Type: text/html; charset=UTF-8
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
</head>
<body>
<p>Hello World! This is HTML...</p>
</body>
</html>
------=_Part_18243133_1346573420.1408991447668--';
$headers = "MIME-Version: 1.0\r\n";
$headers .= "From: Foo <[email protected]>\r\n";
$headers .= 'Content-Type: multipart/alternative;boundary="----=_Part_18243133_1346573420.1408991447668"';
// send email
wp_mail( $to, $subject, $message, $headers );
```
And if you want to change the [default content type](http://codex.wordpress.org/Plugin_API/Filter_Reference/wp_mail_content_type), use:
```
add_filter( 'wp_mail_content_type', 'set_content_type' );
function set_content_type( $content_type ) {
return 'multipart/alternative';
}
```
This will send a multipart message.
So if you check the full raw source of the message, you'll notice that the content type is added twice, once without boundary:
```
MIME-Version: 1.0
Content-Type: multipart/alternative;
boundary="====f230673f9d7c359a81ffebccb88e5d61=="
MIME-Version: 1.0
Content-Type: multipart/alternative; charset=
```
That's the issue.
The source of the problem lies in `pluggable.php` - if we look somewhere here:
```
// Set Content-Type and charset
// If we don't have a content-type from the input headers
if ( !isset( $content_type ) )
$content_type = 'text/plain';
/**
* Filter the wp_mail() content type.
*
* @since 2.3.0
*
* @param string $content_type Default wp_mail() content type.
*/
$content_type = apply_filters( 'wp_mail_content_type', $content_type );
$phpmailer->ContentType = $content_type;
// Set whether it's plaintext, depending on $content_type
if ( 'text/html' == $content_type )
$phpmailer->IsHTML( true );
// If we don't have a charset from the input headers
if ( !isset( $charset ) )
$charset = get_bloginfo( 'charset' );
// Set the content-type and charset
/**
* Filter the default wp_mail() charset.
*
* @since 2.3.0
*
* @param string $charset Default email charset.
*/
$phpmailer->CharSet = apply_filters( 'wp_mail_charset', $charset );
// Set custom headers
if ( !empty( $headers ) ) {
foreach( (array) $headers as $name => $content ) {
$phpmailer->AddCustomHeader( sprintf( '%1$s: %2$s', $name, $content ) );
}
if ( false !== stripos( $content_type, 'multipart' ) && ! empty($boundary) )
$phpmailer->AddCustomHeader( sprintf( "Content-Type: %s;\n\t boundary=\"%s\"", $content_type, $boundary ) );
}
if ( !empty( $attachments ) ) {
foreach ( $attachments as $attachment ) {
try {
$phpmailer->AddAttachment($attachment);
} catch ( phpmailerException $e ) {
continue;
}
}
}
```
Potential solutions
-------------------
So you are wondering, **why have you not reported this at [trac](https://core.trac.wordpress.org/)?** I [already have](https://core.trac.wordpress.org/ticket/31653). To my great surprise, a [different ticket](https://core.trac.wordpress.org/ticket/15448) was created 5 years ago outlining the same problem.
Let's face it, it's been a half decade. In internet years, that is more like 30. The issue has clearly been abandoned and basically will never be fixed (...unless if we resolve it here).
I found a great [thread here](https://wordpress.org/support/topic/using-wp_mail-with-php-generated-attachments) offering a solution, but while his solution works, it breaks emails that do not have custom `$headers` set.
That's where we crash every time. Either the multipart version work fine, and normal unset `$headers` messages don't, or vise verse.
The solution we came up with was:
```
if ( false !== stripos( $content_type, 'multipart' ) && ! empty($boundary) ) {
$phpmailer->ContentType = $content_type . "; boundary=" . $boundary;
}
else {
$content_type = apply_filters( 'wp_mail_content_type', $content_type );
$phpmailer->ContentType = $content_type;
// Set whether it's plaintext, depending on $content_type
if ( 'text/html' == $content_type )
$phpmailer->IsHTML( true );
// If we don't have a charset from the input headers
if ( !isset( $charset ) )
$charset = get_bloginfo( 'charset' );
}
// Set the content-type and charset
/**
* Filter the default wp_mail() charset.
*
* @since 2.3.0
*
* @param string $charset Default email charset.
*/
$phpmailer->CharSet = apply_filters( 'wp_mail_charset', $charset );
// Set custom headers
if ( !empty( $headers ) ) {
foreach( (array) $headers as $name => $content ) {
$phpmailer->AddCustomHeader( sprintf( '%1$s: %2$s', $name, $content ) );
}
}
```
Yes, I know, editing core files are taboo, sit back down... this was a desperate fix and a poor attempt to provide a fix for core.
The problem with our fix is that default emails like new registrations, comment, password reset etc will be delivered as blank messages. So we have a working wp\_mail() script that will send multipart messages but nothing else.
What to do
----------
The aim here is to find a way to send both normal (plain text) and multipart messages **using the core wp\_mail() function** (not a custom sendmail function).
When attempting to solve this, the main problem you will encounter is the amount of time that you'll spend on sending dummy messages, checking if they're received and basically opening a box of aspirin and cursing at Microsoft because you are used to their IE issues while the gremlin here is unfortunately WordPress.
Update
------
The solution posted by @bonger allows `$message` to be an array containing content-type keyed alternates. I have confirmed that it works in all scenarios.
We will allow this question to remain open until bounty runs out to raise awareness about the problem, **maybe to a level where it will be fixed in core.** Feel free to post an alternative solution where `$message` can be a string.
|
The following version of `wp_mail()` is with the patch applied of @rmccue/@MattyRob in the ticket <https://core.trac.wordpress.org/ticket/15448>, refreshed for 4.2.2, which allows `$message` to be an array containing content-type keyed alternates:
```
/**
* Send mail, similar to PHP's mail
*
* A true return value does not automatically mean that the user received the
* email successfully. It just only means that the method used was able to
* process the request without any errors.
*
* Using the two 'wp_mail_from' and 'wp_mail_from_name' hooks allow from
* creating a from address like 'Name <[email protected]>' when both are set. If
* just 'wp_mail_from' is set, then just the email address will be used with no
* name.
*
* The default content type is 'text/plain' which does not allow using HTML.
* However, you can set the content type of the email by using the
* 'wp_mail_content_type' filter.
*
* If $message is an array, the key of each is used to add as an attachment
* with the value used as the body. The 'text/plain' element is used as the
* text version of the body, with the 'text/html' element used as the HTML
* version of the body. All other types are added as attachments.
*
* The default charset is based on the charset used on the blog. The charset can
* be set using the 'wp_mail_charset' filter.
*
* @since 1.2.1
*
* @uses PHPMailer
*
* @param string|array $to Array or comma-separated list of email addresses to send message.
* @param string $subject Email subject
* @param string|array $message Message contents
* @param string|array $headers Optional. Additional headers.
* @param string|array $attachments Optional. Files to attach.
* @return bool Whether the email contents were sent successfully.

So if you put that in your eg "wp-content/mu-plugins/functions.php" file then it will override the WP version. It has a nice usage without any messing around with headers, eg:
```
// Set $to to an hotmail.com or outlook.com email
$to = "[email protected]";
$subject = 'wp_mail testing multipart';
$message['text/plain'] = 'Hello world! This is plain text...';
$message['text/html'] = '<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
</head>
<body>
<p>Hello World! This is HTML...</p>
</body>
</html>';
add_filter( 'wp_mail_from', $from_func = function ( $from_email ) { return '[email protected]'; } );
add_filter( 'wp_mail_from_name', $from_name_func = function ( $from_name ) { return 'Foo'; } );
// send email
wp_mail( $to, $subject, $message );
remove_filter( 'wp_mail_from', $from_func );
remove_filter( 'wp_mail_from_name', $from_name_func );
```
Please note I haven't tested this with actual emails...

<p><a href="http://domain.com/aaa/bbb" rel="nofollow">http://domain.com/aaa/bbb</a></p>
<p>How I can do it? How I can tell WP it is a valid URL, because WP will point to 404 page (aaa page not found).</p>

In your .htaccess you should be able to do something like what is shown by Chris Coyier on CSS Tricks.
Link to example by Chris Coyier: <https://css-tricks.com/snippets/htaccess/subdirectories-redirect-query-string/>
Since you don't have .php in your URL, WordPress has most likely already created RewriteEngine rules for you to not need .php. But the result should still work fine.
**EDIT:**
Another example of this is shown with pretty much the same exact scenario as you.
It's on Apache's Wiki website: <https://wiki.apache.org/httpd/RewriteQueryString>
The example shown to do this in your .htaccess is something like this:
```
RewriteCond %{QUERY_STRING} ^(\w+)=(\w+)$
RewriteRule ^/path /path/%1/%2?
```

<p>I am looking for a method to get the registered metaboxes for a specific post type (or post ID) when on a separate, unrelated post type. I am working on making a custom "editing" post type for a specific client need and want the ability to load the metaboxes without having them be registered to that 'editable' type.</p>
<p><strong>Clarification:</strong></p>
<p>What I am trying to accomplish is the actual display of the metaboxes from another post type. So if my "events" post type has a metabox with date, time, and location, I would want to show those same boxes on a separate post type without actually registering the metabox again.</p>

I am looking for a method to get the registered metaboxes for a specific post type (or post ID) when on a separate, unrelated post type. I am working on making a custom "editing" post type for a specific client need and want the ability to load the metaboxes without having them be registered to that 'editable' type.
**Clarification:**
What I am trying to accomplish is the actual display of the metaboxes from another post type. So if my "events" post type has a metabox with date, time, and location, I would want to show those same boxes on a separate post type without actually registering the metabox again.
|
Wrong Assumptions
-----------------
**@Rarst** or **@Dan-Cameron** answers may work, but assume that when you are viewing a post type editing page, the metaboxes for the other post type are all registered.
There are different case in which that won't happen:
* If metaboxes are registered using [`"add_meta_boxes_{$post_type}"`](https://developer.wordpress.org/reference/hooks/add_meta_boxes_post_type/) hook, instead of the more common, generic `"add_meta_boxes"` they won't be available in the admin page for the *stealer* post type
* Even the generic post hook [`"add_meta_boxes"`](https://developer.wordpress.org/reference/hooks/add_meta_boxes/) pass to hooking callbacks the current post type and the current post object as arguments. It means that registering callbacks may use those arguments in some `if` conditions, so is possible that we are in same situation of previous point
In short, unless you have control on how the metaboxes for some post type *A* are registered, you can't be sure they will be able in post editing page for some post type *B*.
In case you have that control, then [@Rarst answer](https://wordpress.stackexchange.com/a/191951/35541) would do the trick.
In case you have not that control, the only way would be a bit tricky.
IMO your only chance, in that case, is to send an HTTP request (AJAX or via WP HTTP API) to the post edit page of the CPT you want to steal the boxes from. You have to add some request variable that will make the page return the boxes array (probaly serialized or JSON-enconded).
After that, you can merge the boxes returned with the boxes for current post, and you are done.
The point is that such code
* is slow (because additional request)
* is not trivial
So, if you have control on which are all the boxes registered for post a certain post type, is much simpler and faster just register those boxes again for the *stealer* post type.
If you can't be sure which are all the boxes for that post type, then the additional HTTP request is your only chance.
I'll post here a class, that implements that workflow ([here](https://gist.github.com/Giuseppe-Mazzapica/e45bb38565e221876958) as Gist for better readability):
```
class MetaboxStealer
{
private static $stealing;
private $post_type;
private $boxes = [];
/**
* When the request contain special variable, this function will make it
* return a serialized version of $wp_meta_boxes array and die.
*/
public static function init()
{
add_filter('post_updated_messages', function ($messages) {
if (MetaboxStealer::stealing()) {
ob_start();
return [];
}
return $messages;
});
add_action('do_meta_boxes', function () {
if (MetaboxStealer::stealing()) {
ob_end_clean();
global $wp_meta_boxes;
echo serialize($wp_meta_boxes);
die();
}
});
}
/**
* Checks that the request contain a special variable that will make request
* return a serialized version of $wp_meta_boxes array and die.
*
* @return bool
*/
public static function stealing()
{
if (is_null(self::$stealing)) {
$screen = function_exists('get_current_screen') ? get_current_screen() : null;
$stealing = filter_input(INPUT_GET, 'stealing-boxes', FILTER_SANITIZE_STRING);
self::$stealing =
$screen instanceof \WP_Screen
&& $stealing
&& wp_verify_nonce($stealing, $screen->post_type);
}
return self::$stealing;
}
/**
* @param string $post_type Current post type
*/
public function __construct($post_type)
{
$this->post_type = $post_type;
}
/**
* Send a HTTP request to post edit page of a given CPT setting a special
* variable that will make that page return serialized $wp_meta_boxes array.
* After that, so obtained boxes are merged with the boxes for current post type.
*
* @param string $cpt CPT to steal metaboxes from
*/
public function steal($cpt)
{
$vars = [
'post_type' => $cpt,
'stealing-boxes' => wp_create_nonce($cpt),
];
$url = add_query_arg($vars, admin_url('/post-new.php'));
$cookies = [];
foreach ($_COOKIE as $name => $value) {
if ('PHPSESSID' !== strtoupper($name)) {
$cookies[] = new \WP_Http_Cookie([
'name' => $name,
'value' => $value,
]);
}
}
$response = wp_remote_get($url, ['cookies' => $cookies]);
if (! is_wp_error($response)) {
$body = wp_remote_retrieve_body($response);
if (is_serialized($body)) {
$boxes = unserialize($body);
$this->boxes = isset($boxes[$cpt]) ? $boxes[$cpt] : [];
empty($this->boxes) or $this->merge();
}
}
}
/**
* Merge metaboxes for current post type with boxes obtained with
* a HTTP request to another CPT post edit page.
*/
private function merge()
{
global $wp_meta_boxes;
isset($wp_meta_boxes[$this->post_type]) or $wp_meta_boxes[$this->post_type] = [];
foreach ($this->boxes as $context => $priorities) {
foreach ($priorities as $priority => $boxes) {
if (! isset($wp_meta_boxes[$this->post_type][$context])) {
$wp_meta_boxes[$this->post_type][$context] = [];
}
if (! isset($wp_meta_boxes[$this->post_type][$context][$priority])) {
$wp_meta_boxes[$this->post_type][$context][$priority] = [];
}
$wp_meta_boxes[$this->post_type][$context][$priority] = array_merge(
$wp_meta_boxes[$this->post_type][$context][$priority],
$boxes
);
}
}
}
}
```
Notes:
* the method `merge()` is highly derived from Rarst answer
* I've used WP HTTP API to send additional request to keep all in one place, but an AJAX implementation would be nicer
How To Use
----------
Pretty simple.
```
// init the class
add_action('admin_init', ['MetaboxStealer', 'init']);
// use the class to merge boxes for current CPT with boxes for another CPT
add_action('edit_form_after_editor', function ($post) {
$stealer_cpt = 'stealer-cpt';
$steal_from = 'events';
if ($post->post_type === $stealer_cpt) {
$stealer = new MetaboxStealer($post->post_type);
$stealer->steal($steal_from);
// note that you can steal from different CPTs
// $stealer->steal($another_steal_from);
}
});
```
The Saving Issue
----------------
No matter how do you manage to show boxes from one CPT in the post edit page of another CPT, is possible that the saving routine checks the post type before saving post meta in it.
In that case, metaboxes from the other CPT, even if showed, will not be saved and you'll probably need to write another saving routine, if you have no access on the original
one.

<p><strong>UPDATED QUESTION to be CLEARER</strong></p>
<p>Here's my situation:</p>
<ul>
<li><p>Wordpress top navigation has several menu items that jump to an array of posts within a specific category. For example, if you click "necklaces" you will find yourself in the necklaces section. You can click "next" or "previous" buttons and advance to the next necklace post.</p></li>
<li><p>At the top of the page, there is an H2 tag which displays the title by getting its category name:</p>
<pre><code><?php
$category = get_the_category();
echo $category[0]->cat_name;
?>
</code></pre></li>
<li><p>The problem is that all these posts are listed under MULTIPLE categories. The above code only gets the first category. If one post is listed under the categories of "necklaces" as well as "pendants" then it's going to display the wrong title in one of these categories.</p></li>
</ul>
<p>So, I need to have the title display the correct category according to the actual category the user is in at the moment. Currently, when you click "next" or "previous", the title will randomly change depending on which category is listed as first for that particular post.</p>
<p>There are dozens of categories. They all share the single.php template. I am trying to change the title on the single.php template page NOT category.php</p>

Secondly, we need to adjust pagination between single posts in order for us to pass our referrer between single posts. </p>\n\n<p>The problem with referrers is, they are set and controlled by user side. Referrers can be disabled or blocked (like users accessing a site behind a proxy). Just for interest sake, here is very interesting answer to the question <em>In what cases will http referrer be empty</em> taken from <a href=\"https://stackoverflow.com/a/6880668/1908141\">this post on SO</a></p>\n\n<p>It will/may be empty when the enduser</p>\n\n<ul>\n<li>entered the site URL in browser address bar itself.</li>\n<li>visited the site by a browser-maintained bookmark.</li>\n<li>visited the site as first page in the window/tab.</li>\n<li>switched from a https URL to a http URL.</li>\n<li>switched from a https URL to a different https URL.</li>\n<li>has security software installed (antivirus/firewall/etc) which strips the referrer from all requests.</li>\n<li>is behind a proxy which strips the referrer from all requests.</li>\n<li>visited the site programmatically (like, <a href=\"http://php.net/manual/en/ref.curl.php\" rel=\"nofollow noreferrer\">curl</a>) without setting the referrer header (searchbots!).</li>\n</ul>\n\n<p>You would want to read the other answers there as well for extra insight</p>\n\n<p>I sat with similar issue and was looking for a more reliable way to set and pass referrers, and this led to <a href=\"https://wordpress.stackexchange.com/q/170007/31545\">this question</a> and a wonderful <a href=\"https://wordpress.stackexchange.com/a/170016/31545\">answer by @gmazzap</a></p>\n\n<p>So your solution would be based on something similar. We will be adding a special parameter to our URL which will serve as referrer (<em>I have made the assumption that your posts are from the build in post type <code>post</code> and taxonomy <code>category</code></em>)</p>\n\n<ul>\n<li><p>Identify our category pages and add a referrer to the post links via the <code>post_link</code> filter. This referrer will hold the category id. You can use the category name, but this can become quite messy in your URL. The choice is all up you.</p>\n\n<pre><code>add_filter('post_link', function( $permalink ) // Change to post_type_link for custom post type posts\n{\n if ( is_category() // Change to is_tax() for custom taxonomy pages\n && ( $cat = get_queried_object() ) \n ) {\n $permalink = esc_url( add_query_arg( array( 'ref' => $cat->term_id ), $permalink ) );\n }\n return $permalink;\n});\n</code></pre>\n\n<p>This will give you a URL like the following on your single post page if you click on a post link on the category page</p>\n\n<pre><code>http://example.com/wordpress/post-name?ref=1\n</code></pre></li>\n<li><p>We must have a way to read and use that info from the URL in order to make it useful. For this, we must add a the query arg <code>ref</code> so Wordpress can read it</p>\n\n<pre><code>add_filter( 'query_vars', function ( $vars ) \n{\n $vars[] = 'ref';\n return $vars;\n});\n</code></pre></li>\n<li><p>All you need to do now, is to check if the single post was a referred post, get the value from the URL and use that info to display the correct category name (<strong><em>NOTE:</strong> This piece of code goes into your <code>single.php</code></em>)</p>\n\n<pre><code>$referrer = filter_input( INPUT_GET, 'ref', FILTER_VALIDATE_INT ); // This validate and checks if our referrer \"ref\" is set\nif ( $referrer ) {\n $category = get_category( $referrer );\n echo '<h2>' . $category->name . '</h2>';\n}\n</code></pre></li>\n</ul>\n\n<p>The above is just a rough draft of what you can do to accomplish this, it just gives you a foundation to work from. You can tweak and modify it as needed.</p>\n\n<p>On your single pages, you will also need to get your referrer and pass that to your next and previous post links in order to maintain this feature between posts. I have written an answer for pagination based on this, it is quite bulky though and can use some clean up. There are some parts that I have handled here now, and there are also parts that you will most probably never need which you can just remove. You can work through it and modify and adjust it as needed. </p>\n\n<p>I am busy rewritting the complete pagination function ( using better and cleaner php functionality ) with some extra features, the classes are done, it is just the final pieces putting everything into functional functions that is giving me a nightmare, and to be honest, I haven't got back to working on the project for quite some time now as I really don't have much time at night. When it will be completed is still a mystery. But the idea and code from what I have given in that specific answer should do the trick for you. You can check out my answer and referrer pagination function <a href=\"https://wordpress.stackexchange.com/a/173041/31545\">here</a></p>\n\n<h2>EDIT</h2>\n\n<p>I have quickly written a small plugin which covers the referrer and new pagination links to carry the referrer across multiple single posts. This pagination links will also page between single posts from the referrer</p>\n\n<p>What this means is, if a single post was clicked from <code>category B</code>, and this post has three categories, <code>category A</code>, <code>category B</code> and <code>category C</code>, the next and previous adjacent post will be from <code>category B</code>. If you go to either post, the adjacent post from that clicked single post will also be from <code>category B</code> etc</p>\n\n<p>I have commented the code so you should be able to follow it better and also adjust and modify it as needed. Just copy and paste this code in a plugin file and activate it. Alternatively, copy the code (without the plugin header of course) and paste it as is into your <code>functions.php</code> (<strong><em>NOTE:</strong> This only works for the build in taxonomy <code>category</code> and the build in post type <code>post</code>.

**UPDATED QUESTION to be CLEARER**
Here's my situation:
* Wordpress top navigation has several menu items that jump to an array of posts within a specific category. For example, if you click "necklaces" you will find yourself in the necklaces section. You can click "next" or "previous" buttons and advance to the next necklace post.
* At the top of the page, there is an H2 tag which displays the title by getting its category name:
```
<?php
$category = get_the_category();
echo $category[0]->cat_name;
?>
```
* The problem is that all these posts are listed under MULTIPLE categories. The above code only gets the first category. If one post is listed under the categories of "necklaces" as well as "pendants" then it's going to display the wrong title in one of these categories.
So, I need to have the title display the correct category according to the actual category the user is in at the moment. Currently, when you click "next" or "previous", the title will randomly change depending on which category is listed as first for that particular post.
There are dozens of categories. They all share the single.php template. I am trying to change the title on the single.php template page NOT category.php
|
In order for this to work, you will need to know from where the single post was refered from and if the referrer is a valid one. Secondly, we need to adjust pagination between single posts in order for us to pass our referrer between single posts.
The problem with referrers is, they are set and controlled by user side. Referrers can be disabled or blocked (like users accessing a site behind a proxy). Just for interest sake, here is very interesting answer to the question *In what cases will http referrer be empty* taken from [this post on SO](https://stackoverflow.com/a/6880668/1908141)
It will/may be empty when the enduser
* entered the site URL in browser address bar itself.
* visited the site by a browser-maintained bookmark.
* visited the site as first page in the window/tab.
* switched from a https URL to a http URL.
* switched from a https URL to a different https URL.
* has security software installed (antivirus/firewall/etc) which strips the referrer from all requests.
* is behind a proxy which strips the referrer from all requests.
* visited the site programmatically (like, [curl](http://php.net/manual/en/ref.curl.php)) without setting the referrer header (searchbots!).
You would want to read the other answers there as well for extra insight
I sat with similar issue and was looking for a more reliable way to set and pass referrers, and this led to [this question](https://wordpress.stackexchange.com/q/170007/31545) and a wonderful [answer by @gmazzap](https://wordpress.stackexchange.com/a/170016/31545)
So your solution would be based on something similar. We will be adding a special parameter to our URL which will serve as referrer (*I have made the assumption that your posts are from the build in post type `post` and taxonomy `category`*)
* Identify our category pages and add a referrer to the post links via the `post_link` filter. This referrer will hold the category id. You can use the category name, but this can become quite messy in your URL. The choice is all up you.
```
add_filter('post_link', function( $permalink ) // Change to post_type_link for custom post type posts
{
if ( is_category() // Change to is_tax() for custom taxonomy pages
&& ( $cat = get_queried_object() )
) {
$permalink = esc_url( add_query_arg( array( 'ref' => $cat->term_id ), $permalink ) );
}
return $permalink;
});
```
This will give you a URL like the following on your single post page if you click on a post link on the category page
```
http://example.com/wordpress/post-name?ref=1
```
* We must have a way to read and use that info from the URL in order to make it useful. For this, we must add a the query arg `ref` so Wordpress can read it
```
add_filter( 'query_vars', function ( $vars )
{
$vars[] = 'ref';
return $vars;
});
```
* All you need to do now, is to check if the single post was a referred post, get the value from the URL and use that info to display the correct category name (***NOTE:*** This piece of code goes into your `single.php`)
```
$referrer = filter_input( INPUT_GET, 'ref', FILTER_VALIDATE_INT ); // This validate and checks if our referrer "ref" is set
if ( $referrer ) {
$category = get_category( $referrer );
echo '<h2>' . $category->name . '</h2>';
}
```
The above is just a rough draft of what you can do to accomplish this, it just gives you a foundation to work from. You can tweak and modify it as needed.
On your single pages, you will also need to get your referrer and pass that to your next and previous post links in order to maintain this feature between posts. I have written an answer for pagination based on this, it is quite bulky though and can use some clean up. There are some parts that I have handled here now, and there are also parts that you will most probably never need which you can just remove. You can work through it and modify and adjust it as needed.
I am busy rewritting the complete pagination function ( using better and cleaner php functionality ) with some extra features, the classes are done, it is just the final pieces putting everything into functional functions that is giving me a nightmare, and to be honest, I haven't got back to working on the project for quite some time now as I really don't have much time at night. When it will be completed is still a mystery. But the idea and code from what I have given in that specific answer should do the trick for you. You can check out my answer and referrer pagination function [here](https://wordpress.stackexchange.com/a/173041/31545)
EDIT
----
I have quickly written a small plugin which covers the referrer and new pagination links to carry the referrer across multiple single posts. This pagination links will also page between single posts from the referrer
What this means is, if a single post was clicked from `category B`, and this post has three categories, `category A`, `category B` and `category C`, the next and previous adjacent post will be from `category B`. If you go to either post, the adjacent post from that clicked single post will also be from `category B` etc
I have commented the code so you should be able to follow it better and also adjust and modify it as needed. Just copy and paste this code in a plugin file and activate it. Alternatively, copy the code (without the plugin header of course) and paste it as is into your `functions.php` (***NOTE:*** This only works for the build in taxonomy `category` and the build in post type `post`. You should modify it accordingly to your needs according to post type and custom taxonomy)

You should now add the following in your single.php:

```
$referrer = filter_input( INPUT_GET, 'ref', FILTER_VALIDATE_INT ); // This validate and checks if our referrer "ref" is set
if ( $referrer ) {
$category = get_category( $referrer );
echo '<h2>' . $category->name . '</h2>';
}
```
* To display your post links
```
if ( function_exists( 'next_adjacent_post_link' ) )
next_adjacent_post_link();
if ( function_exists( 'previos_adjacent_post_link' ) )
previos_adjacent_post_link();
```
Just add your relevant mark up to your links. Also check the accepted arguments to customize the text the links display.
This should lay the foundation to set you on your way. You should be able to customize this to suit your exact needs

<p>I've been developing a website on wordpress for some time now and came across some issues but until now I could figure it out, not today... Yesterday I've worked some more on the website and today when I came back to do some more work the pages on my site that are part of my navigation menu didn't load properly (minus the home page that is static and a news page that is the index page), they were loading the index.php page. Also with my posts in the news(index) page the load the index page instead of the post content. The URLs appear correct, but the loaded page is the index one. This doesn´t happen with the other pages I have that are not in the navigation menu and also with some custom post types, everything works fine there. The strange thing is that it happened from nothing, maybe is a quick fix... or not, I'm not an expert.</p>
<p>Thank you in advance and if you could help me I would aprecciate it!</p>

I've been developing a website on wordpress for some time now and came across some issues but until now I could figure it out, not today... Yesterday I've worked some more on the website and today when I came back to do some more work the pages on my site that are part of my navigation menu didn't load properly (minus the home page that is static and a news page that is the index page), they were loading the index.php page. Also with my posts in the news(index) page the load the index page instead of the post content. The URLs appear correct, but the loaded page is the index one. This doesn´t happen with the other pages I have that are not in the navigation menu and also with some custom post types, everything works fine there. The strange thing is that it happened from nothing, maybe is a quick fix... or not, I'm not an expert.
Thank you in advance and if you could help me I would aprecciate it!

In order for this to work, you will need to know from where the single post was refered from and if the referrer is a valid one. Secondly, we need to adjust pagination between single posts in order for us to pass our referrer between single posts.
The problem with referrers is, they are set and controlled by user side. Referrers can be disabled or blocked (like users accessing a site behind a proxy). Just for interest sake, here is very interesting answer to the question *In what cases will http referrer be empty* taken from [this post on SO](https://stackoverflow.com/a/6880668/1908141)
It will/may be empty when the enduser
* entered the site URL in browser address bar itself.
* visited the site by a browser-maintained bookmark.
* visited the site as first page in the window/tab.
* switched from a https URL to a http URL.
* switched from a https URL to a different https URL.
* has security software installed (antivirus/firewall/etc) which strips the referrer from all requests.
* is behind a proxy which strips the referrer from all requests.
* visited the site programmatically (like, [curl](http://php.net/manual/en/ref.curl.php)) without setting the referrer header (searchbots!).
You would want to read the other answers there as well for extra insight
I sat with similar issue and was looking for a more reliable way to set and pass referrers, and this led to [this question](https://wordpress.stackexchange.com/q/170007/31545) and a wonderful [answer by @gmazzap](https://wordpress.stackexchange.com/a/170016/31545)
So your solution would be based on something similar. We will be adding a special parameter to our URL which will serve as referrer (*I have made the assumption that your posts are from the build in post type `post` and taxonomy `category`*)
* Identify our category pages and add a referrer to the post links via the `post_link` filter. This referrer will hold the category id. You can use the category name, but this can become quite messy in your URL. The choice is all up you.
```
add_filter('post_link', function( $permalink ) // Change to post_type_link for custom post type posts
{
if ( is_category() // Change to is_tax() for custom taxonomy pages
&& ( $cat = get_queried_object() )
) {
$permalink = esc_url( add_query_arg( array( 'ref' => $cat->term_id ), $permalink ) );
}
return $permalink;
});
```
This will give you a URL like the following on your single post page if you click on a post link on the category page
```
http://example.com/wordpress/post-name?ref=1
```
* We must have a way to read and use that info from the URL in order to make it useful. For this, we must add a the query arg `ref` so Wordpress can read it
```
add_filter( 'query_vars', function ( $vars )
{
$vars[] = 'ref';
return $vars;
});
```
* All you need to do now, is to check if the single post was a referred post, get the value from the URL and use that info to display the correct category name (***NOTE:*** This piece of code goes into your `single.php`)
```
$referrer = filter_input( INPUT_GET, 'ref', FILTER_VALIDATE_INT ); // This validate and checks if our referrer "ref" is set
if ( $referrer ) {
$category = get_category( $referrer );
echo '<h2>' . $category->name . '</h2>';
}
```
The above is just a rough draft of what you can do to accomplish this, it just gives you a foundation to work from. You can tweak and modify it as needed.
On your single pages, you will also need to get your referrer and pass that to your next and previous post links in order to maintain this feature between posts. I have written an answer for pagination based on this, it is quite bulky though and can use some clean up. There are some parts that I have handled here now, and there are also parts that you will most probably never need which you can just remove. You can work through it and modify and adjust it as needed.
I am busy rewritting the complete pagination function ( using better and cleaner php functionality ) with some extra features, the classes are done, it is just the final pieces putting everything into functional functions that is giving me a nightmare, and to be honest, I haven't got back to working on the project for quite some time now as I really don't have much time at night. When it will be completed is still a mystery. But the idea and code from what I have given in that specific answer should do the trick for you. You can check out my answer and referrer pagination function [here](https://wordpress.stackexchange.com/a/173041/31545)
EDIT
----
I have quickly written a small plugin which covers the referrer and new pagination links to carry the referrer across multiple single posts. This pagination links will also page between single posts from the referrer
What this means is, if a single post was clicked from `category B`, and this post has three categories, `category A`, `category B` and `category C`, the next and previous adjacent post will be from `category B`. If you go to either post, the adjacent post from that clicked single post will also be from `category B` etc
I have commented the code so you should be able to follow it better and also adjust and modify it as needed. Just copy and paste this code in a plugin file and activate it. Alternatively, copy the code (without the plugin header of course) and paste it as is into your `functions.php` (***NOTE:*** This only works for the build in taxonomy `category` and the build in post type `post`. You should modify it accordingly to your needs according to post type and custom taxonomy)

You should now add the following in your single.php:
* To display your custom text
```
$referrer = filter_input( INPUT_GET, 'ref', FILTER_VALIDATE_INT ); // This validate and checks if our referrer "ref" is set
if ( $referrer ) {
$category = get_category( $referrer );
echo '<h2>' . $category->name . '</h2>';
}
```
* To display your post links
```
if ( function_exists( 'next_adjacent_post_link' ) )
next_adjacent_post_link();
if ( function_exists( 'previos_adjacent_post_link' ) )
previos_adjacent_post_link();
```
Just add your relevant mark up to your links. Also check the accepted arguments to customize the text the links display.
This should lay the foundation to set you on your way. You should be able to customize this to suit your exact needs

Let's say I've the following file in my parent theme folder: `'theme-folder/inc/custom.php'`
Then I created a child theme.
How can I check if that file exists in the child theme, then fetch it, otherwise fetch it from the parent theme?
`get_template_directory()` always fetches the file from the parent theme.
While `get_stylesheet_directory()` requires the file to exists in the child theme.
|
[`locate_template`](https://codex.wordpress.org/Function_Reference/locate_template) will attempt to find the specified file in the child theme, and fall back to the parent theme if it does not exist:
```
locate_template('inc/custom.php', true);
```
Setting the second parameter to `true` causes it to require the file instead of just determining the path.
As the name suggests, `locate_template` is meant for loading template files. It has some additional overhead that you most likely don't need for loading libraries. A stripped down version would be:
```
function load_theme_file($path) {
if ( file_exists( STYLESHEETPATH . '/' . $path )) {
include( STYLESHEETPATH . '/' . $path );
} else {
require( TEMPLATEPATH . '/' . $path );
}
}
```
Usage:
```
load_theme_file('inc/custom.php');
```
---
Edit: I just wanted to provide a quick note about potential issues with this overall approach.
Letting a child theme override files works well for templates, but for libraries there is more room for error. If a child theme needs to modify a single function, you would have to copy that entire file, overriding every function in that file in the process.
If the parent theme is updated and changes have been made to any of the functions in the overwritten file it can cause problems. You can mitigate this issue by breaking up your libraries into smaller chunks, but that can make your code base harder to maintain.
A better solution, in my opinion, is to use an object oriented approach. Allow a child theme to *extend* classes you define and then use the child theme's class. In the implementing classes the child theme would only have to define methods it needs to overwrite. In the parent theme you could specify which methods should not be overwritten by making them `final`.
You can also mitigate the need for child themes to replace entire files by using filters and actions generously.

function register_my_plugin_extra_replacements() {

add_action( 'wpseo_register_extra_replacements', 'register_my_plugin_extra_replacements' );

You can now replace your %%excerpt%% with %%mycustomdesc%%

You say that you are not getting errors, which I would have expected but [it looks as though WordPress uses `require_once()`](https://core.trac.wordpress.org/browser/tags/4.2.2/src/wp-admin/includes/admin.php#L39) so you are probably safe:

```
This kind of hack tends to indicate that you are doing something wrong though.

<p>I'm trying to hide a large amount of categories from my category widget. I've tried a few plugins but none of them seem to want to let me use the dropdown option. I looked into the widget_categories_args hook and that seems to be what I want but I can't get it to work. </p>
<p>Anyways here's my code</p>
<pre><code>function widget_categories_args_filter( $cat_args ) {
$exclude_arr = array( 57,61,63,56,55,62,52,53,54,67,65 );
if( isset( $cat_args['exclude'] ) && !empty( $cat_args['exclude'] ) )

I'm trying to hide a large amount of categories from my category widget. I've tried a few plugins but none of them seem to want to let me use the dropdown option. I looked into the widget\_categories\_args hook and that seems to be what I want but I can't get it to work.
Anyways here's my code
```
function widget_categories_args_filter( $cat_args ) {
$exclude_arr = array( 57,61,63,56,55,62,52,53,54,67,65 );
if( isset( $cat_args['exclude'] ) && !empty( $cat_args['exclude'] ) )
$exclude_arr = array_unique( array_merge( explode( ',', $cat_args['exclude'] ), $exclude_arr ) );
$cat_args['exclude'] = implode( ',', $exclude_arr );
return $cat_args;
}
add_filter( 'widget_categories_args', 'widget_categories_args_filter', 10, 1 );
```
I Took that from here: <https://codex.wordpress.org/Plugin_API/Filter_Reference/widget_categories_args>
I'm putting this in my theme's functions.php. That shouldn't matter even though the function is set for plugins, right?

I know this post is pretty old, but because I came across the same issue and this post came up higher than one with a solution, I figured I'd add this, which worked for me.
Source: <http://coffeecupweb.com/how-to-exclude-or-hide-categories-from-category-widget-in-wordpress-sidebar/>
```
//Hide categories from WordPress category widget
function exclude_widget_categories($args){
$exclude = "1,4,8,57,80";
$args["exclude"] = $exclude;
return $args;
}
add_filter("widget_categories_args","exclude_widget_categories");

<p>I have my post image thumbnails set with: </p>
<pre><code> add_theme_support('post-thumbnails');
set_post_thumbnail_size(1280, 436, true);
add_image_size('general-thumb', 600, 339, true);
</code></pre>
<p>They are resized into two columns with the following css:</p>
<pre><code> max-width: 100%;
height: auto;
</code></pre>
<p>The columns they are displayed in are about 348px wide.</p>
<p>The issue is that when I upload an image that is less than the dimensions 600x339 in either height or width, they show up incorrectly on the page.</p>
<p>I think the reason for this is that 600x339 is the starting 'box' within which an image is cropped. It's then resized to fill the width of the column while retaining the aspect ratio of the original image size. </p>
<p>What are some ways I can fix this with wordpress' functions or css hacks?</p>
<p>What I think needs to happen so that the images can resize dynamically is have every uploaded image automatically cropped to the correct aspect ratio without resizing it. But this needs to start with the original image's width and height, not the predefined box dimensions. </p>
<p>Thanks!</p>

I believe it centers the image and takes it evenly from top and bottom.</em></p>\n\n<p><strong>Soft cropping</strong> reduces the whole image proportionately, maintaining the whole image. <em>For example: That 800x600 image you uploaded would soft crop down to smallest maximum dimension 200h, leaving the width proportionately 267w.</em></p>\n\n<p>In this case, I believe the OP definitely wants to <strong>Hard Crop</strong>, as indicated in the code.</p>\n\n<p>The issue that is being encountered is that WP will not scale up an image to match the proportions.

The 'fix' I know most people use is to scale the image in a desktop program before uploading it if it absolutely cannot be gotten at a larger scale already.</p>\n\n<p>OP is looking for a solution that will allow WP to scale up the image to the requested dimensions. This solution can be found here: <a href=\"https://wordpress.stackexchange.com/questions/173318/how-to-scale-up-image-into-thumbnail-without-distorting-it\">How to scale up image into thumbnail without distorting it?</a> </p>\n\n<p>Axlmedia (the source quoted) also adds this warning about the solution:</p>\n\n<blockquote>\n <p>The slight downside (not much to worry about with the server space we have today) is that if you for example upload a 16×16 favicon to your media library, it will be cropped and upscaled to all larger thumbnail sizes available. So, some more images will be created.</p>\n</blockquote>\n\n<p>As for older images, WordPress does not go back and revert your older thumbnails. These settings would only work on everything new from point of install onward. Once your solution is set, you can find a plugin or two that will go back in and rescale every image to the new settings. I do not know if it will work with the added upscale function. The two plugins suggested by user Stanislau Ladutska may offer a quicker overall solution.</p>\n"

It sounds like your problem occurs before the image is cropped/ resized and displayed in the page - the original image is too small.
You can require minimum dimensions for uploaded images, see: [How to Require a Minimum Image Dimension for Uploading?](https://wordpress.stackexchange.com/questions/28359/how-to-require-a-minimum-image-dimension-for-uploading)
Then, to resize the uploaded image without cropping it, define the image size with a 'soft crop' using 'false' in the third parameter:
```
add_image_size('general-thumb', 600, 339, false);
```
Finally, using the image as a background image for an element may be an alternative way of getting the sizing right.
You can position the element within your layout with whatever height, width, minimum height etc is required and use the CSS `background-size` to fill/ position the image within the element.
For example:
```
background-size: contain;
```
Will ensure the image is as large as possible without hiding any part of it.
See: <https://developer.mozilla.org/en-US/docs/Web/CSS/background-size>

If you start using this theme, you are doomed in the sense that you can't change it later without breaking the site.</p>\n\n<p>My personal opinion on theme is that it should only work on the visual aspect and leave the functionality part to the plugin. But so many themes break this rule and it is frustrating. Once you start using it, you are married to it for life. If you want to divorce, there are so much Alimony you have to pay that you will hardly think about it. In my opinion, it should be like a date rather than a marriage in the first place.</p>\n\n<p>So, what's the best option for you?</p>\n\n<p>First question, Do you really need custom post type? It depends on which functionality you want to incorporate. It's the question that you have to answer yourself. Personally, I believe it gives a lot of choice and I would've used it just for the fact that it separates my lyrics from post.</p>\n\n<p>IMO for you the best option is to create a plugin that creates the custom post types for lyrics. Now the functionality is in the plugin and you can switch theme any time you want as long as the plugin is activated. You should give only a basic template in your plugin so that everything works without giving much visual consideration as it won't match with your theme anyway. Now in your theme, you need to create a template to display the custom post type properly. Every time you change a plugin, you will need to create a template so that it matches that theme style.</p>\n\n<p>It means that you will still need to modify a little bit when you change theme to match everything perfectly, but even without it your site will work without failing to display the content. If coded properly, it might give nice view even without a template. And lastly modifying theme default template isn't going to take much time.</p>\n"

The theme is using a custom post type, in this case, "lyrics". Converting the old posts over to it should be as simple as writing a single query to update the old posts to the new post type.
The query will be something like:
```
UPDATE `wp_posts` SET post_type = "lyrics" WHERE post_type = "post";
```
Just as an added precaution, run this one first to ensure that all the posts you think should be converted will be affected and check the results:
```
SELECT * FROM wp_posts WHERE post_type = "post";
```

I am trying to delete records from my custom table but it does not delete anything.
Here is my code:
```
<?php
global $wpdb;
$retrieve_data = $wpdb->get_results( "SELECT * FROM wp_paypal" );
// some code to display here...
?>
<form method="post" enctype="multipart/form-data">
<td><input type="submit" name="delete" value="Delete" /></td>
</form>
<?php
$myid= $retrieved_data->id;
if (isset($_POST['delete'])) {
//global $wpdb;
$wpdb->query(
'DELETE FROM $wpdb->paypal
WHERE id = "'.$myid.'"
'
);
}
}
```
|
Try to use `$wpdb->prefix` insted of `$wpdb` in Delete query.
Example:
```
$wpdb->query(
'DELETE FROM '.$wpdb->prefix.'paypal
WHERE id = "'.$myid.'"'
);
```

So basically this is my original code :
```

while( have_posts() ) {

get_template_part( 'inc/template-parts/content', $post_layout );
// and some other stuff

I tried the advice from this thread - [How do I check if a post has a post thumbnail in `WP_Query`?](https://wordpress.stackexchange.com/questions/45909/how-do-i-check-if-a-post-has-a-post-thumbnail-in-wp-query)
But without any success. When I implement the code all posts disappear from the front page.
This is the code I tried:
```
$query = new WP_Query( $thumbs );

}
}
```
Any advice will be appreciated!

You need to define your arguments **before** you pass them to `WP_Query`, not after. Also, your `meta_query` should be an array of an array, not just an array
This
```
$query = new WP_Query($thumbs);
$thumbs = array(
'meta_query' => array('key' => '_thumbnail_id')
);
```
should look like this
```
$thumbs = array(
'meta_query' => array(
array(
'key' => '_thumbnail_id'
)
)
);
$query = new WP_Query($thumbs);
```
EDIT
----
Just a few extra notes
* Make sure to reset postdata after a custom query. Just add `wp_reset_postdata();` before you close your `if` statement and just after closing your `while` statement
* I believe that a custom query might not be necessary here. If I read your question correctly, you can simply use `pre_get_posts` to alter the main query. You shouldn't use a custom query just because you want to alter the main query

You could add this function to your functions.php file.
```
add_filter( 'sidebars_widgets', 'disable_all_widgets' );
function disable_all_widgets( $sidebars_widgets ) {
$sidebars_widgets = array( false );
return $sidebars_widgets;
}
```
You could also use the [Wordpress conditional tags](http://codex.wordpress.org/Conditional_Tags) to disable widgets only on certain pages. For example; this would only disable widgets on the home page.
```
add_filter( 'sidebars_widgets', 'disable_all_widgets' );
function disable_all_widgets( $sidebars_widgets ) {
if ( is_home() )
$sidebars_widgets = array( false );
return $sidebars_widgets;
}
```

<p>For example I have an image that's very long but want to show a cropped version of that but when people click my blog post from the homepage they see the longer version.</p>
<p>I tried doing using the plugin "Custom CSS Manager" with the code:</p>

max-height: 375px;
overflow: hidden;
}
</code></pre>
<p>Which works but I can't figure out a way to crop my image to the specific 600X375 that I want. Like for some pictures I don't want it to start from the top but close to the top if that makes sense. That code is good but won't let me do that from what I understand.</p>
<p>Or do I need to take a simpler approach? If anyone knows how to make my homepage blog image shorter that I can control the 600X375 crop but the post page has the full image please share. I have been trying to figure this out for the last two days but with no avail. Thanks for any help. </p>

<p>i'm really getting crazy about this. after hours of trials, i can't get out of this.</p>
<p>I'm trying to pass a php variable value to an enqueued jquery script but i can't. </p>
<p>here is my code.</p>
<p>php : </p>
<pre><code>function itinerary_enqueuescripts(){
wp_enqueue_script('itenqueue', JSONURL.'/js/loadjson.js', array('jquery'));
wp_localize_script( 'itenqueue', 'itajax', array( 'ajaxurl' => "hithere" ) );
}
add_action('wp_enqueue_scripts', 'itinerary_enqueuescripts');
</code></pre>
<p>in my loadjson.js file i have a simple </p>
<pre><code>var _latitude = 43.309;
var _longitude = 8.499;
var jsonPath = itajax.ajaxurl; //and should transform, in this example, in hithere
</code></pre>
<p>But when the script is enqueued, the var jsonPath as the value of itajax.ajaxurl :)</p>
<p>The scripts gets enqueued correctly, in this example i make a simple variable declaration (just to let out problems.. e.g. the script gets enqueued too early).</p>
<p>Funny thing (and perhaps here's the clue, this is quite a copy/paste from another plugin of mine, for a function that points to admin-ajax.php for front end posting. It's the same syntax, with different variable names of course, but in this case it doesn't work).</p>
<p>Thanks for any clue. (i tried quite anything, registering-localizing-enqueueing, enqueueing in wp_footer at the very last.. even changing double qoutes to single quotes :) Now i suppose i really must miss something.</p>

Funny thing (and perhaps here's the clue, this is quite a copy/paste from another plugin of mine, for a function that points to admin-ajax.php for front end posting. It's the same syntax, with different variable names of course, but in this case it doesn't work).
Thanks for any clue. (i tried quite anything, registering-localizing-enqueueing, enqueueing in wp\_footer at the very last.. even changing double qoutes to single quotes :) Now i suppose i really must miss something.

You could add this function to your functions.php file.
```
add_filter( 'sidebars_widgets', 'disable_all_widgets' );
function disable_all_widgets( $sidebars_widgets ) {
$sidebars_widgets = array( false );
return $sidebars_widgets;
}
```
You could also use the [Wordpress conditional tags](http://codex.wordpress.org/Conditional_Tags) to disable widgets only on certain pages. For example; this would only disable widgets on the home page.
```
add_filter( 'sidebars_widgets', 'disable_all_widgets' );
function disable_all_widgets( $sidebars_widgets ) {
if ( is_home() )
$sidebars_widgets = array( false );
return $sidebars_widgets;
}
```

Before I start, I must say that your terminology is quite confusing and plain wrong. You should take your time and read through [my answer](https://wordpress.stackexchange.com/a/158223/31545) to this question: [Is There a Difference Between Taxonomies and Categories?](https://wordpress.stackexchange.com/questions/158206/is-there-a-difference-between-taxonomies-and-categories/158223#158223)
As I stated before, there is no `in_term()` function to check if a post has a specific term. There is however a [`has_term()`](https://codex.wordpress.org/Function_Reference/has_term) function which accepts the term as first parameter and the taxonomy name as second parameter. So your condition should look like this: (*if this is for a specific post type outside the loop*)
```
global $post;
if ( $post->post_type == 'my_post_type' // checks the post type of the post
&& is_single() // Checks if this is a single post
&& has_term( 'term-name or id or slug', 'my_taxonomy', $post->ID ) // Check if post has specific term
) {
// Do something if our condition is true
}
```

First of all, never ever use `query_posts`. It breaks the main function and all plugins and functions relying on the main query object. For custom queries, use `WP_Query` or `get_posts` if aren't looking to paginate the query
As for the following line
```
'orderby' => 'rr_recommends_count',
```
I can tell you that `rr_recommends_count` is an invalid value to the `orderby` parameter. Suspect that this is actually the key name, and the values are all numerical in that key, so you would use the `meta_value_num` value to the `orderby` parameter which is a valid value
```
'orderby' => 'meta_value_num',
```

I have to execute custom PHP code after new post is saved with all it's meta data.
My question is how to achieve that? Tried with **save\_post** action, but it executes before meta records are saved, so I cannot use it in this case.
So, how can I run my custom function after post with all related data is saved in database?
**UPDATED:** I tried to achieve with next code in functions.php file:
```
add_action( 'save_post', 'wpse41912_save_post' );
function wpse41912_save_post() {
// get info about latest added post
$args = array( 'numberposts' => '1', 'post_type' => 'post' );
$recent_posts = wp_get_recent_posts( $args );
$myFunc_latest_id = $recent_posts[0]['ID']; // id of the latest post
$myFunc_post_details = get_post($myFunc_latest_id);
print_r($myFunc_post_details);
// how to execute php code when all post meta is added?
}
```
Thank you in advance!

For **NEW** post type 'post' use `draft_to_publish` action hook:
```
function fpw_post_info( $post ) {
if ( 'post' == $post->post_type ) {
// echo '<pre>'; print_r( $post ); echo '<br />';
// $meta = get_post_meta( $post->ID ); print_r( $meta ); echo '</pre>'; die();
// your custom code goes here...
}
}
add_action( 'draft_to_publish', 'fpw_post_info', 10, 1 );
```
In your callback function `$post` is your post as `WP_post` object. You'll get post's meta calling `get_post_meta` function.
For **NEW** or **UPDATED** post type 'post' use `publish_post` action hook:
```
function fpw_post_info( $id, $post ) {
// echo '<pre>'; print_r( $post ); echo '<br />';
// $meta = get_post_meta( $post->ID ); print_r( $meta ); echo '</pre>'; die();
// your custom code goes here...
}
add_action( 'publish_post', 'fpw_post_info', 10, 2 );
```
In this case the callback function takes two parameters!

I'm experiencing an odd situation while running an UPDATE with `$wpdb->query()`.
Given the `users` table, with columns `user_id` (Primary Key) and `status`, and the user 3 existing and with status 0, I run the following query:
```
update users
set status = 8
where user_id = 3
```
On my machine, running the query with `$wpdb->query`, I get the result of 1: 1 row affected.
On another machine I run the query with the PHP code and always get 0 rows: before running the query I checked the status and it was 0, and if I run it with another tool (e.g. command line mysql client), it says me that is 1 affected row.
The query method of wpdb returns the number of affected rows in case of update (<https://codex.wordpress.org/Class_Reference/wpdb#Running_General_Queries>).
My machine and the remote one have got the same PHP version (5.4.40), same mysql server version, and same wordpress version (4.2.2). About the mysql PHP extensions, in local I've installed mysql, mysqli and mysqlnd: on the other machine I've got mysql and mysqli.
Is there someone with some clues about the possible reason? Thank you.
**Edit 1**
I tried to run the query also with [the `update` method](https://codex.wordpress.org/Class_Reference/wpdb#UPDATE_rows), but the result is always 0 rows affected. I start thinking that I found an incoherency in the $wpdb abstraction layer.
|
`wpdb` [uses PHP's `mysqli_affected_rows()` or `mysql_affected_rows()`](https://core.trac.wordpress.org/browser/tags/4.2.2/src/wp-includes/wp-db.php#L1686), which can be disabled [via an argument in `php.ini`](http://php.net/manual/en/ini.core.php#ini.disable-functions). I am guessing that that is what has happened. Check the `disabled_functions` line in your `php.ini` file and remove the references to those function.
Of the top of my head, I am not sure if extensions like Suhosin mess with that function but that is certainly possible.

You can add custom text or html using this action.
```
add_action( 'woocommerce_email_after_order_table', 'add_order_email_instructions', 10, 2 );
function add_order_email_instructions( $order, $sent_to_admin ) {
if ( ! $sent_to_admin ) {

I have a custom post type named `project` which has
```
'capability_type' => 'post'
```
while registering using `register_post_type`.
In my theme files and also `functions.php` file, I have situations where I should check if the project to be edited is authored by the user or not.
So I use this:
```
if ( !current_user_can( 'edit_post', $porject_id ) ) return;
```
where `$project_id` is post id of the project to be edited.
For example I have a page template named `single_project.php` where I can show single posts in project post type to users and I want these people can see each project single page:
1. administrators
2. editors
3. the contributor (post author)
but using the above code, It is ok with administrators and editors, while not for the contributor himself!
When I use:
```php
var_dump( current_user_can( 'edit_post', $project_id ) );
```
with the contributor logged-in account, it returns `false`, while this:
```php
var_dump( current_user_can( 'edit_posts' ) ); // (with trailing 's')
```
returns `true` (but for every post, not just does for him).
Any help with this?
|
using `map_meta_cap` I added `edit_post` per post cap to user
```
function my_map_meta_cap( $caps, $cap, $user_id, $args ){
if ( 'edit_post' == $cap ) {
$post = get_post( $args[0] );
$post_type = get_post_type_object( $post->post_type );
$caps = array();
if ( $user_id == $post->post_author )
$caps[] = $post_type->cap->edit_posts;
else
$caps[] = $post_type->cap->edit_others_posts;
}
return $caps;
}
add_filter( 'map_meta_cap', 'my_map_meta_cap', 10, 4 );

<p>I have two custom fields:</p>
<ul>
<li><code>meta_key1</code> is boolean (<code>0</code> or <code>1</code>). </li>
<li><code>meta_key2</code> is a date value - <code>20150623</code> for example.</li>
</ul>
<p>Not all <code>meta_key2</code> fields have an explicit value. It looks like their being treated as an empty string <code>''</code>. </p>
<p>I'd like to find all posts that have a <code>meta_key2</code> (date) value that is greater than today or have a <code>meta_key1</code> value that is true.</p>
<p>This is the order I'd like them to display.</p>
<blockquote>
<ol>
<li><code>key2.meta_value >= today ASC</code></li>
<li><code>key1.meta_value = TRUE ordered by date ASC</code> (those with dates given first).</li>
</ol>
</blockquote>
<p>Part of the issue is that fields with an empty date parameter appear to be treated as <code>0</code> and thus come first in <code>ASC</code> order. I've attempted to use <code>COALESCE</code> to account for this and have had some success but I'm hung up on one part. I can't get the posts that <code>key1.meta_value = FALSE</code> and <code>key2.meta_value is >= today</code> to display in <code>ASC</code> order.</p>
<p>Here's my query:</p>
<pre><code>$meta_key1 = 'prog_ongoing';
$meta_key2 = 'prog_date_start';
$start_date = date('Ymd');
$postids = $wpdb->get_col( $wpdb->prepare(
"
SELECT DISTINCT key1.post_id
FROM $wpdb->postmeta key1
INNER JOIN $wpdb->postmeta key2
ON key2.post_id = key1.post_id
AND key2.meta_key = %s
WHERE key1.meta_key = %s
AND key1.meta_value is TRUE
OR key2.meta_value >= %d
ORDER BY COALESCE(NULLIF(key1.meta_value, 0), 0) DESC, COALESCE(NULLIF(key2.meta_value, ''), $start_date) ASC, key2.meta_value ASC
",
$meta_key2,
$meta_key1,
$start_date
) );
</code></pre>
<p>I'm not sure my <code>COALESCE</code> statement on <code>key1.meta_value</code> is doing anything. Thanks for any insight on this.</p>

Not all `meta_key2` fields have an explicit value. It looks like their being treated as an empty string `''`.
I'd like to find all posts that have a `meta_key2` (date) value that is greater than today or have a `meta_key1` value that is true.

I've attempted to use `COALESCE` to account for this and have had some success but I'm hung up on one part. I can't get the posts that `key1.meta_value = FALSE` and `key2.meta_value is >= today` to display in `ASC` order.
Here's my query:
```
$meta_key1 = 'prog_ongoing';

$start_date = date('Ymd');
$postids = $wpdb->get_col( $wpdb->prepare(

SELECT DISTINCT key1.post_id

",
$meta_key2,
$meta_key1,
$start_date
) );
```
I'm not sure my `COALESCE` statement on `key1.meta_value` is doing anything. Thanks for any insight on this.

One problem with the query is that the self-join with the ambiguous `WHERE` gives you a crossed dataset (which is masked by the `DISTINCT`), so it would be simpler to use `wp_post` as a base to attach the joins that precisely match the keys, eg
```
SELECT p.ID, key1.meta_value as prog_ongoing, key2.meta_value as prog_date_start
FROM $wpdb->posts p
INNER JOIN $wpdb->postmeta key1
ON key1.post_id = p.ID
AND key1.meta_key = %s
INNER JOIN $wpdb->postmeta key2
ON key2.post_id = p.ID
AND key2.meta_key = %s
```
which gives a linear dataset. Then you could add (or not) the `WHERE` clause to restrict the data:
```
WHERE key1.meta_value IS TRUE OR key2.meta_value >= %d
```
and for the `ORDER BY` use a `CASE` statement single field sort:
```
ORDER BY CASE
WHEN key2.meta_value >= %d THEN CONCAT('A', key2.meta_value)
WHEN key1.meta_value AND key2.meta_value THEN CONCAT('B', key2.meta_value)
WHEN key1.meta_value THEN 'C'
ELSE 'D'
END ASC
```
or something similar, the above needing the `prepare` args to be:
```
$meta_key1,
$meta_key2,
$start_date, $start_date
```
You could use the `posts_orderby` filter to do something similar using `WP_Query` (although it uses a method that produces crossed datasets, requiring it to have to use a `GROUP BY`, which can complicate things). For instance
```
$args = array(
'posts_per_page' => -1,
'post_type' => 'cpt_program',
'meta_query' => array(
'ongoing' => array(
'key' => 'prog_ongoing',
),
'start_date' => array(
'key' => 'prog_date_start',
)
),
);
add_filter( 'posts_orderby', $func = function ( $orderby, $query ) {
$start_date = date('Ymd');
global $wpdb;
$orderby = $wpdb->prepare(
"
CASE
WHEN mt1.meta_value >= %d THEN CONCAT('A', mt1.meta_value)
WHEN {$wpdb->postmeta}.meta_value AND mt1.meta_value THEN CONCAT('B', mt1.meta_value)
WHEN {$wpdb->postmeta}.meta_value THEN 'C'
ELSE 'D'
END ASC
"
, $start_date
);
return $orderby;
}, 10, 2 );
$query = new WP_Query( $args );
remove_filter( 'posts_orderby', $func, 10, 2 );
```

<p>What i am trying to accomplish is have the correct number of WordPress active sidebars outputted. So that they can be styled with css example: if 3 sidebars are active you get col-3 if (1) if you col-1.</p>
<p>The code above works. My concern is can it be improved, is this the right way to do it ? Or can increments be used for example: $i = 0; $i++; instead of an array.</p>

$sidebars = array(
is_active_sidebar( 'footer-4' ),
is_active_sidebar( 'footer-3' ),
is_active_sidebar( 'footer-2' ),
is_active_sidebar( 'footer-1' ),
);
$col = 0;
foreach ( $sidebars as $sidebar ) {
if ( $sidebar ) {
$col++;
}
}
echo 'col-'.$col.'';
```
What i am trying to accomplish is have the correct number of WordPress active sidebars outputted. So that they can be styled with css example: if 3 sidebars are active you get col-3 if (1) if you col-1.
The code above works. My concern is can it be improved, is this the right way to do it ? Or can increments be used for example: $i = 0; $i++; instead of an array.
Thanks.

Use the `array_filter()` function, which will remove every array element that has false as the value. Then you can count the array length. So your example would look like this:
```
$sidebars = array(
is_active_sidebar( 'footer-4' ),
is_active_sidebar( 'footer-3' ),
is_active_sidebar( 'footer-2' ),
is_active_sidebar( 'footer-1' ),
);
$active_sidebars = array_filter($sidebars);
echo 'col-'.count($active_sidebars);
```
