"text": "<p>Missing GET request variables are sometimes a symptom of improper rewrite rules in the web-server's configuration files. In the case of Apache, rewrites are most often implemented using the <a href=\"http://httpd.apache.org/docs/current/mod/mod_rewrite.html\" rel=\"nofollow\"><code>mod_rewrite</code></a> module's directives in the WordPress installation's directory-level <code>.htaccess</code> configuration file - however, a faulty rewrite rule could also be present in higher-level configuration files (directory, vhost, primary configuration, etc.).</p>\n\n<p>By default, WordPress routes every request for anything except existing files and directories to <code>index.php</code> using a configuration similar to the following:</p>\n\n<pre><code><IfModule mod_rewrite.c>\nRewriteEngine On\nRewriteBase /\nRewriteRule ^index\\.php$ - [L]\nRewriteCond %{REQUEST_FILENAME} !-f\nRewriteCond %{REQUEST_FILENAME} !-d\nRewriteRule . /index.php [L]\n</IfModule>\n</code></pre>\n\n<p>There are two modifications that will cause these directives to drop the querystring in the process of rewriting the request:</p>\n\n<ul>\n<li><p>The <a href=\"http://httpd.apache.org/docs/current/rewrite/flags.html#flag_qsd\" rel=\"nofollow\">discard querystring flag</a>. This is added to the square brackets at the end of a <code>RewriteRule</code> directive as either <code>QSD</code> or <code>qsdiscard</code>. If this flag is present for <em>either</em> of the <code>RewriteRule</code> directives in the configuration above, the querystring will be discarded for virtually every request handled by WordPress. For example:</p>\n\n<pre><code>RewriteRule ^index\\.php$ - [L,QSD]\n</code></pre></li>\n<li><p>Any use of a <code>?</code> in a <code>RewriteRule</code> directive's substitution string (without the <a href=\"http://httpd.apache.org/docs/current/rewrite/flags.html#flag_qsa\" rel=\"nofollow\">append querystring flag</a>). Specifying <em>any</em> querystring (even a single <code>?</code> without any subsequent key/value pairs) in the substitution will result in the rewrite completely replacing the original querystring. For example:</p>\n\n<pre><code>RewriteRule . /index.php? [L]\n</code></pre>\n\n<p>or</p>\n\n<pre><code>RewriteRule . /index.php?foo=bar [L]\n</code></pre>\n\n<p>If it is desireable to append a custom GET variable to every rewrite, the append querystring flag can be specified in the brackets as <code>QSA</code> or <code>qsappend</code> in order to merge the querystring in the substitution with the original querystring instead of completely overwriting it:</p>\n\n<pre><code>RewriteRule . /index.php?foo=bar [L,QSA]\n</code></pre></li>\n</ul>\n"

Missing GET request variables are sometimes a symptom of improper rewrite rules in the web-server's configuration files. In the case of Apache, rewrites are most often implemented using the [`mod_rewrite`](http://httpd.apache.org/docs/current/mod/mod_rewrite.html) module's directives in the WordPress installation's directory-level `.htaccess` configuration file - however, a faulty rewrite rule could also be present in higher-level configuration files (directory, vhost, primary configuration, etc.).
By default, WordPress routes every request for anything except existing files and directories to `index.php` using a configuration similar to the following:
```
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
```
There are two modifications that will cause these directives to drop the querystring in the process of rewriting the request:
* The [discard querystring flag](http://httpd.apache.org/docs/current/rewrite/flags.html#flag_qsd). This is added to the square brackets at the end of a `RewriteRule` directive as either `QSD` or `qsdiscard`. If this flag is present for *either* of the `RewriteRule` directives in the configuration above, the querystring will be discarded for virtually every request handled by WordPress. For example:
```
RewriteRule ^index\.php$ - [L,QSD]
```
* Any use of a `?` in a `RewriteRule` directive's substitution string (without the [append querystring flag](http://httpd.apache.org/docs/current/rewrite/flags.html#flag_qsa)). Specifying *any* querystring (even a single `?` without any subsequent key/value pairs) in the substitution will result in the rewrite completely replacing the original querystring. For example:
```
RewriteRule . /index.php? [L]
```
or
```
RewriteRule . /index.php?foo=bar [L]
```
If it is desireable to append a custom GET variable to every rewrite, the append querystring flag can be specified in the brackets as `QSA` or `qsappend` in order to merge the querystring in the substitution with the original querystring instead of completely overwriting it:
```
RewriteRule . /index.php?foo=bar [L,QSA]
```

You are trying to use the\_title() and the\_excerpt() functions outside the [wordpress loop](https://codex.wordpress.org/The_Loop), therefore, they will not work.
I suggest you try something like :
```
$args = array( 'posts_per_page' => 12, 'orderby' => 'rand', 'post_status' => 'publish', 'offset' => 1);
$query = new WP_Query($args);
while($query->have_posts()){
$query->the_post();
// the_excerpt() will now work as expected
}

<p>I am currently using the .htaccess file in cPanel to password protect my Wordpress website. There are a list of whitelisted IP addresses that can bypass the login form. </p>
<p>I would like to whitelist a page, but I don't have a .php or .html file to whitelist. It is a page within Wordpress, so I realize I may have to find a plugin or another way to do this. I don't want to have to manually password protect literally every single page just so I can have one page open to the public, so... there must be a way to do this. </p>
<p>If anyone can help out, it'd be greatly appreciated!</p>
<p>Thanks!</p>

I am currently using the .htaccess file in cPanel to password protect my Wordpress website. There are a list of whitelisted IP addresses that can bypass the login form.
I would like to whitelist a page, but I don't have a .php or .html file to whitelist. It is a page within Wordpress, so I realize I may have to find a plugin or another way to do this. I don't want to have to manually password protect literally every single page just so I can have one page open to the public, so... there must be a way to do this.
If anyone can help out, it'd be greatly appreciated!
Thanks!

If you are just wanting a simple "login" you could use `htpasswd` and `htaccess`. WordPress sites already have the `htaccess` in the main directory.
Add an `.htpasswd` file at the same level as your root HTML folder. Example:
```
.
├── public_html
| └── wordpress
| └── .htaccess
└── .htpasswd
```
Use a tool like [htpasswd generator](http://www.htaccesstools.com/htpasswd-generator/) to generate a username/password pair. Then add this to your `.htpasswd` file.
Find the path `$_SERVER["DOCUMENT_ROOT"]` may provide some insight for you.
Edit WP's `.htaccess`. After the `#END WORDPRESS#` add
```
AuthType Basic
AuthName "Restricted Area"
AuthUserFile /var/www/mysite/.htpasswd
require valid-user
```
If you need more detailed instructions see [this post](https://www.zigpress.com/2014/09/22/password-protecting-an-entire-wordpress-site/).
However, this does not address your request about IP Validation. [This question](https://stackoverflow.com/questions/10419592/htaccess-htpasswd-bypass-if-at-a-certain-ip-address) on StackOverflow may address it.
You would update the `.htaccess` file to read
```
AuthUserFile /var/www/mysite/.htpasswd
AuthName "Please Log In"
AuthType Basic
require valid-user
Order allow,deny
Allow from xxx.xxx.xxx.xxx
satisfy any
```

Ok this was really tricky. I have so far managed to work around it by lying to the WordPress global `$wp_query`. Here is how.
In your theme's `functions.php` you can add these functions to show 7 posts on first page, and 9 posts on any other page.
Okay, that code works so far but you'll notice that the pagination is incorrect on first page. Why? This is because WordPress uses the posts per page on first page (which is 7) and get the number of pages by doing division like ( 1000 / 7 ) = total posts. But what we need is to make the pagination take into account that on next pages we'll show 9 posts per page, not 7. With filters, you cannot do this but if you add this hack to your template just before `the_posts_pagination()` function it'll work as you expect.
**The trick is to change the `max_num_pages` inside $wp\_query global variable to our custom value and ignore WP calculation during the pagination links display only for first page.**
```
global $wp_query;
// Needed for first page only
if ( ! $wp_query->is_paged ) {
$all_posts_except_fp = ( $wp_query->found_posts - 7 ); // Get us the found posts except those on first page
$wp_query->max_num_pages = ceil( $all_posts_except_fp / 9 ) + 1; // + 1 the first page we have containing 7 posts
}
```
And this is the code to put in functions.php to filter the query.
```
add_action('pre_get_posts', 'myprefix_query_offset', 1 );
function myprefix_query_offset(&$query) {
if ( ! $query->is_home() ) {
return;
}
$fp = 7;
$ppp = 9;
if ( $query->is_paged ) {
$offset = $fp + ( ($query->query_vars['paged'] - 2) * $ppp );
$query->set('offset', $offset );
$query->set('posts_per_page', $ppp );
} else {
$query->set('posts_per_page', $fp );
}
}
add_filter('found_posts', 'myprefix_adjust_offset_pagination', 1, 2 );
function myprefix_adjust_offset_pagination($found_posts, $query) {
$fp = 7;
$ppp = 9;
if ( $query->is_home() ) {
if ( $query->is_paged ) {
return ( $found_posts + ( $ppp - $fp ) );
}
}
return $found_posts;
}
```

I have a small filter below. It does a regular expression replace of a particular string when the user saves the draft.
However, using this filter causes the warning "The backup of this post in your browser is different from the version below."
Is there a way to 'tell' Wordpress not to display the warning when that filter runs?
To re-create:
1. Create a draft post.
2. In the body, enter a line of text:
rcq[whatever]
eg.
rcqTestMsg
3. Save the draft.
Here is the code.
UPDATE: WHAT I THINK IS GOING ON: I think that somehow this is triggering the autosave.js CheckPost() function which (apparently) compares the text on screen with the current saved version. Is there a way to disable the autosave or revision just when this filter is triggered? Or is there something in my code that is confusing the revision system?

The way to avoid this error is to make sure the `wp-saving-post` cookie is being set to a value of `[post id]-saved`, as seen [here](https://github.com/WordPress/WordPress/blob/10970701d7fbcaf504dd7d35d0e75c5c2b0c2e52/wp-includes/js/autosave.js#L457). As you can see, if that occurs, then WordPress won't complain about the difference, because it then knows that the post was saved properly.
Also take a look at [this line](https://github.com/WordPress/WordPress/blob/a72be13ec0b57a2831d75540fd1892d1bd121f3b/wp-admin/post.php#L197) and note that WordPress [handles this for you](https://github.com/WordPress/WordPress/blob/a72be13ec0b57a2831d75540fd1892d1bd121f3b/wp-admin/post.php#L197) already.

Finally, check to be sure you're not filtering the content, and then immediately redirecting, or exiting the script, or doing something else that would prevent [this line](https://github.com/WordPress/WordPress/blob/a72be13ec0b57a2831d75540fd1892d1bd121f3b/wp-admin/post.php#L197) from running once your filter is applied. That too, may lead to the problem that you're seeing.

I am trying to make a page that displays a *[Custom Post Type](https://codex.wordpress.org/Post_Types#Custom_Post_Types)*.
I need for all post to be displayed twice. Once at a list of products and once as a modal. I am able to display the product list on the page but I can't get the second post query for the modals to work.
**Products page**:
```
<div>
<main>
<?php
if ( have_posts() ) : ?>
<header class="page-header">
<?php
the_archive_title( '<h1 class="page-title">', '</h1>' );
the_archive_description( '<div class="archive-description">', '</div>' );
?>
</header> <!-- .page-header -->
<?php
/* Start the Loop */
$args = array( 'post_type' => 'kollektion' );
$loop = new WP_Query( $args );
if( $loop ->have_posts() ) :
while( $loop->have_posts() ) : $loop->the_post();
get_template_part( 'template-parts/content-kollektion', get_post_format() );
endwhile;
endif;
the_posts_navigation();
else :
get_template_part( 'template-parts/content-kollektion', 'none' );
endif;
wp_reset_postdata();
?>
</main> <!-- #main -->
</div> <!-- #primary -->
<!-- modal Kollektion 02 -->
<div class="modalDialog">
<section class="kollektion-slider">
<?php
rewind_posts();
/* Start the Loop */
$args = array( 'post_type' => 'kollektion' );
$loop = new WP_Query( $args );
if( $loop ->have_posts() ) :
while( $loop->have_posts() ) :
$loop->the_post();
get_template_part( 'template-parts/content-kollektion-modal', get_post_format() );
endwhile;
endif;
wp_reset_postdata();
?>
</section>
</div>
```
`content-kollektion-modal.php`:
```
<div id="post-modal<?php the_ID(); ?>">
<div>
<a href="#close" title="Close" class="close">X</a>
<h2>Modal Box</h2>
<img src="<?php the_field('image_collection'); ?>" />
</div>
</div>
```

You can Query a lot of time in the same page and all the query that you execute will work perfect irrespective of the custom post type that you choose.
>
> Note: Once after you finish the Wp\_Query at the first time you need to `reset` the `Wp_Query` after the execution of the code.
>
>
>
```
wp_reset_query(); // This will reset all the global variables to "".
```
`wp_reset_query()` restores the $wp\_query and global post data to the original main query. This function should be called after query\_posts(), if you must use that function. As noted in the examples below, it's heavily encouraged to use the pre\_get\_posts filter to alter query parameters before the query is made.
Not only by this method you can reset the `Wp_Query` there are other methods that you can follow up for resetting the `post data` and as well as the `$args`.
Quick Reference About the Resetting Query options.
1. `wp_reset_query()`- best used after a query\_posts loop to reset a custom query
2. `wp_reset_postdata()` - best used after custom or multiple loops created with WP\_Query
3. `rewind_posts()` - best for re-using the same query on the same page.
I hope this is a useful round-up of when & how to reset/rewind the WordPress loop
**wp\_reset\_postdata()**
```
$random_post = new WP_query();
$random_post->query('cat=3&showposts=1&orderby=rand');
while ($random_post->have_posts()) : $random_post->the_post();
<a href="<?php the_permalink() ?>" title="<?php the_title(); ?>">
<img src="<?php echo get_post_meta($random_post->ID, 'featured', true); ?>">
</a>
endwhile;
wp_reset_postdata();
```
>
> When to use: best used after custom or multiple loops created with WP\_Query.
>
>
>
**wp\_reset\_query()**
```
<?php query_posts('posts_per_page=3');
if (have_posts()) : while (have_posts()) : the_post(); ?>
<h1><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h1>
<?php endwhile; endif; ?>
<?php wp_reset_query(); ?>
```
>
> When to use: best used after a query\_posts loop to reset things after a custom query.
>
>
>
**rewind\_posts()**
```
if (have_posts()) : while (have_posts()) : the_post(); ?>
<h1><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h1>
<?php endwhile; endif; ?>
<?php rewind_posts(); ?>
<?php while (have_posts()) : the_post(); ?>
<?php the_content(); ?>
<?php endwhile; ?>
```
So, while `wp_reset_query` and `wp_reset_postdata` reset the entire query object, rewind\_posts simply resets the post count, as seen for the function in the `wp-includes/query.php` file:
```
// rewind the posts and reset post index
function rewind_posts() {
$this->current_post = -1;
if ( $this->post_count > 0 ) {
$this->post = $this->posts[0];
}
}
```
>
> When to use: best for re-using the same query on the same page.
>

Do you have any access to the server? SSH access? If you can get to a command line on the server you could try one of these commands. Using sudo would try and run the command as an administrator, so you would need a password:
```
unlink /path/to/symlink
sudo unlink /path/to/symlink
rm /path/to/symlink
sudo rm /path/to/symlink
```

if ( get_post_time() <= strtotime( '-1 day' ) ) {

<p>I am trying to create a shortcode to display the posts count in a category.
I have successfully done this using this code:</p>
<pre><code>// Add Shortcode to show posts count inside a category
function add_count_of_posts_in_category() {
$term = get_term( 7, 'category' );
$count = $term->count;
echo $count;
}
add_shortcode( 'show-posts-count', 'add_count_of_posts_in_category' );
</code></pre>
<p>However, this means that I need to specify the <code>ID</code> of the category for the shortcode to work. Which means that i need to create a shortcode per category, which is useless.</p>
<p>I am trying to find a way to modify the category ID part with a variable, so that I can use the shortcode like this:
<code>[show-posts-count="cars"]</code> to display the post count in the category called cars.
I can't find a way to do so.</p>
<p>Your help is much appreciated.</p>
<p><strong>EDIT: 29/09/2016</strong>
After getting the code working, I am trying to expand the function to count the posts in the child category too.</p>
<p>So if the main category does not have posts, but has 2 subcategories, each has posts, then when I use the shortcode on the main category, the displayed number is the sum of all the posts in the main category (if any), in addition to, the number of posts in the sub-categories, and the sub-sub-categories..etc</p>
<p>I tried using <code>get_term_children( $term, $taxonomy );</code>, but did not know how to get the post count of subcategories then add them together.</p>

So if the main category does not have posts, but has 2 subcategories, each has posts, then when I use the shortcode on the main category, the displayed number is the sum of all the posts in the main category (if any), in addition to, the number of posts in the sub-categories, and the sub-sub-categories..etc
I tried using `get_term_children( $term, $taxonomy );`, but did not know how to get the post count of subcategories then add them together.
|
### The shortcode
```
// Add Shortcode to show posts count inside a category
function category_post_count( $atts ) {
$atts = shortcode_atts( array(
'category' => null
), $atts );
// get the category by slug.
$term = get_term_by( 'slug', $atts['category'], 'category');
return ( isset( $term->count ) ) ? $term->count : 0;
}
add_shortcode( 'category_post_count', 'category_post_count' );
```
### Usage
```
[category_post_count category="category_slug_or_name"]
```
### If you want to get the count by name, not slug change this
```
$term = get_term_by( 'slug', $atts['category'], 'category');
```
to this:
```
$term = get_term_by( 'name', $atts['category'], 'category');
```

<p>I want to delete all the resized images while leaving the original image. I have more than 20 GB of unused data taking up room on the server. For example:</p>
<ul>
<li>first-image-name.jpg</li>
<li>first-image-name-72x72.jpg</li>
<li>first-image-name-150x150.jpg</li>
<li>first-image-name-250x250.jpg</li>
<li>first-image-name-300x300.jpg</li>
<li>first-image-name-400x400.jpg</li>
<li>first-image-name-1024x1024.jpg</li>
<li>second-image-name.jpg</li>
<li>second-image-name-72x72.jpg</li>
<li>second-image-name-150x150.jpg</li>
<li>second-image-name-250x250.jpg</li>
<li>second-image-name-300x300.jpg</li>
<li>second-image-name-400x400.jpg</li>
<li>second-image-name-1024x1024.jpg</li>
</ul>
<p>Is there a way to delete all the resized images and disable creating such ones in the future?</p>

You want to be sure to leave the original image, or else you are simply deleting the entire image. Any image file name with an extra <code>- ###x###.jpg</code> is an auto generated image.

The benefit of this is that thumbs are only created for images/sizes that are actually required by your site.

"text": "<p>A majority of the answers covered how to stop creating future default image sizes but this doesnt account for creating any custom sizes in your theme but here is another solution to add to <code>functions.php</code>:</p>\n\n<pre><code>function wpse_240765_unset_images( $sizes ){\n unset( $sizes[ 'thumbnail' ]);\n unset( $sizes[ 'medium' ]);\n unset( $sizes[ 'medium_large' ] );\n unset( $sizes[ 'large' ]);\n unset( $sizes[ 'full' ] );\n return $sizes;\n}\nadd_filter( 'intermediate_image_sizes_advanced', 'wpse_240765_unset_images' );\n</code></pre>\n\n<p>and you can also turn off future default image generation by setting the images to zero:</p>\n\n<p><a href=\"https://i.stack.imgur.com/7VTBX.png\" rel=\"noreferrer\"><img src=\"https://i.stack.imgur.com/7VTBX.png\" alt=\"enter image description here\"></a></p>\n\n<p>but to remove the images other then the originals I've ran into your same issue when I forgot to set it to not do it and what I did was:</p>\n\n<ul>\n<li><p>Download all the photos locally using an SFTP service, I love <a href=\"https://panic.com/transmit/\" rel=\"noreferrer\">Transmit</a> (paid) but you can use something like <a href=\"https://filezilla-project.org/\" rel=\"noreferrer\">Filezilla</a> (free) .</p></li>\n<li><p>Download all the files to a directory. </p></li>\n</ul>\n\n<p>I'm on a Mac but any terminal that allows bash will work. I coded a simple bash script:</p>\n\n<pre><code># !/bin/bash\n\nUSERNAME=vader\nDIRECTORY=\"/Users/$USERNAME/desktop/question240765\"\nfor imageWithSize in $(find \"$DIRECTORY\" -type f -regex '.*/[a-z-]*-[0-9].*.txt$'); do\n cd $DIRECTORY\n echo rm $imageWithSize\ndone\n</code></pre>\n\n<p>The folder is located on my desktop, and for the question I named it <code>question240765</code>. I used <code>.txt</code> files to test this but you can change it to <code>.jpg</code>. I saved it as a bash file <code>image_dust.sh</code> so that it will allow me to modify or enhance later down the road. Run the script first with the <code>echo</code> and you could even dump it to a file with changing the line:</p>\n\n<pre><code>echo rm $imageWithSize \n</code></pre>\n\n<p>to:</p>\n\n<pre><code>echo rm $imageWithSize >> result.txt\n</code></pre>\n\n<p>which will log everything to the file result.txt and allow you to browse it before really removing them. If all is well change that line to:</p>\n\n<pre><code>rm $imageWithSize\n</code></pre>\n\n<p>If you're curious here is what the regex does:</p>\n\n<ul>\n<li><code>[a-z-]*</code> looks for filenames like <code>foo-bar</code> or <code>fo-fo-bar</code>. if you have uppercase letters in your name use <code>[A-Za-z-]*</code></li>\n<li><code>-[0-9]</code> after the filename it looks for the remaining <code>-</code> (dash) with a number <code>[0-9]</code></li>\n<li><code>.*.txt</code> looks for anything after the first digit to the end of the name with the extension.</li>\n</ul>\n\n<p>After completing the scripting and running it. You could blow everything away on your site and re-upload the images. If you're worried about file size I would even use <code>imagemagick</code> but I prefer <code>sips</code> to reduce the compression size of the images.</p>\n"

Is there a way to delete all the resized images and disable creating such ones in the future?

A majority of the answers covered how to stop creating future default image sizes but this doesnt account for creating any custom sizes in your theme but here is another solution to add to `functions.php`:
```
function wpse_240765_unset_images( $sizes ){
unset( $sizes[ 'thumbnail' ]);
unset( $sizes[ 'medium' ]);
unset( $sizes[ 'medium_large' ] );
unset( $sizes[ 'large' ]);
unset( $sizes[ 'full' ] );
return $sizes;
}
add_filter( 'intermediate_image_sizes_advanced', 'wpse_240765_unset_images' );
```
and you can also turn off future default image generation by setting the images to zero:
[](https://i.stack.imgur.com/7VTBX.png)
but to remove the images other then the originals I've ran into your same issue when I forgot to set it to not do it and what I did was:
* Download all the photos locally using an SFTP service, I love [Transmit](https://panic.com/transmit/) (paid) but you can use something like [Filezilla](https://filezilla-project.org/) (free) .
* Download all the files to a directory.
I'm on a Mac but any terminal that allows bash will work. I coded a simple bash script:
```
# !/bin/bash
USERNAME=vader
DIRECTORY="/Users/$USERNAME/desktop/question240765"
for imageWithSize in $(find "$DIRECTORY" -type f -regex '.*/[a-z-]*-[0-9].*.txt$'); do
cd $DIRECTORY
echo rm $imageWithSize
done
```
The folder is located on my desktop, and for the question I named it `question240765`. I used `.txt` files to test this but you can change it to `.jpg`. I saved it as a bash file `image_dust.sh` so that it will allow me to modify or enhance later down the road. Run the script first with the `echo` and you could even dump it to a file with changing the line:
```
echo rm $imageWithSize
```
to:
```
echo rm $imageWithSize >> result.txt
```
which will log everything to the file result.txt and allow you to browse it before really removing them. If all is well change that line to:
```
rm $imageWithSize
```
If you're curious here is what the regex does:
* `[a-z-]*` looks for filenames like `foo-bar` or `fo-fo-bar`. if you have uppercase letters in your name use `[A-Za-z-]*`
* `-[0-9]` after the filename it looks for the remaining `-` (dash) with a number `[0-9]`
* `.*.txt` looks for anything after the first digit to the end of the name with the extension.
After completing the scripting and running it. You could blow everything away on your site and re-upload the images. If you're worried about file size I would even use `imagemagick` but I prefer `sips` to reduce the compression size of the images.

<p>Good morning,
actually i'm going to start with a new entrepreneur project and I'm thinking about build the website in Wordpress but I'll need to upload many GB of video everyday. There's some limit about the upload or the quality of the video?
Will I be able to upload also from a FTP like Filezilla?</p>
<p>Thanks</p>

Good morning,
actually i'm going to start with a new entrepreneur project and I'm thinking about build the website in Wordpress but I'll need to upload many GB of video everyday. There's some limit about the upload or the quality of the video?
Will I be able to upload also from a FTP like Filezilla?
Thanks

A majority of the answers covered how to stop creating future default image sizes but this doesnt account for creating any custom sizes in your theme but here is another solution to add to `functions.php`:
```
function wpse_240765_unset_images( $sizes ){
unset( $sizes[ 'thumbnail' ]);
unset( $sizes[ 'medium' ]);
unset( $sizes[ 'medium_large' ] );
unset( $sizes[ 'large' ]);
unset( $sizes[ 'full' ] );
return $sizes;
}
add_filter( 'intermediate_image_sizes_advanced', 'wpse_240765_unset_images' );
```
and you can also turn off future default image generation by setting the images to zero:
[](https://i.stack.imgur.com/7VTBX.png)
but to remove the images other then the originals I've ran into your same issue when I forgot to set it to not do it and what I did was:
* Download all the photos locally using an SFTP service, I love [Transmit](https://panic.com/transmit/) (paid) but you can use something like [Filezilla](https://filezilla-project.org/) (free) .
* Download all the files to a directory.
I'm on a Mac but any terminal that allows bash will work. I coded a simple bash script:
```
# !/bin/bash
USERNAME=vader
DIRECTORY="/Users/$USERNAME/desktop/question240765"
for imageWithSize in $(find "$DIRECTORY" -type f -regex '.*/[a-z-]*-[0-9].*.txt$'); do
cd $DIRECTORY
echo rm $imageWithSize
done
```
The folder is located on my desktop, and for the question I named it `question240765`. I used `.txt` files to test this but you can change it to `.jpg`. I saved it as a bash file `image_dust.sh` so that it will allow me to modify or enhance later down the road. Run the script first with the `echo` and you could even dump it to a file with changing the line:
```
echo rm $imageWithSize
```
to:
```
echo rm $imageWithSize >> result.txt
```
which will log everything to the file result.txt and allow you to browse it before really removing them. If all is well change that line to:
```
rm $imageWithSize
```
If you're curious here is what the regex does:
* `[a-z-]*` looks for filenames like `foo-bar` or `fo-fo-bar`. if you have uppercase letters in your name use `[A-Za-z-]*`
* `-[0-9]` after the filename it looks for the remaining `-` (dash) with a number `[0-9]`
* `.*.txt` looks for anything after the first digit to the end of the name with the extension.
After completing the scripting and running it. You could blow everything away on your site and re-upload the images. If you're worried about file size I would even use `imagemagick` but I prefer `sips` to reduce the compression size of the images.

<p>The first query is working fine individually. Vouchers have a day, a start time and an end time. I'm grabbing the current time (e.g 11:10) and trying to show posts where the <code>$time_now</code> comes BETWEEN the <code>start_time</code> and <code>end_time</code>. Are you not able to pass an array into the <code>key</code>?</p>

How can i create Plugin of This???
|
i agree with the other answers, but neither addressed flushing the re-write rules. If you don't add this, it will confuse your users when they activate the plugin and still can't access the custom postypes on the front.
The other problem you're going to have is that LOTS of people will use testimonials so if your clients load a plugin that uses testimonials and is using the same postype or if they were previously using another plugin that had a CPT testimonials, there will be conflicts.
It is better if you prefix your identifier with a short namespace that identifies your plugin, theme or website that implements the custom post type (instead of testimonials, say "haroon\_testimonials" to ensure no one else will be using your post type in their systems.
Then to address post links on the front (so they see www.example.com/testimoinals/1 instead of www.example.com/haroon-testimonials/1
you'll need to use a re-write back to testimonials:
```
'rewrite' => array('slug' => 'locations'),
```
Here is a sample code i use:
```
<?php
/**
* @package rt_create_cpt
* @version 1.0
*/
/*
Plugin Name: Custom Post Creation by RT
Description: A Plugin to create CPT
Author: RT, Inc
Version: 3.4
Author URI: http://
*/
add_action( 'init', 'rt_custom_post' );
function rt_custom_post() {
register_post_type( 'rt_locations',
array(
'labels' => array(
'name' => __( 'Locations' ),
'singular_name' => __( 'Location' ),
'add_new' => _x('Add New Location', 'Location'),
'add_new_item' => __("Add New Location"),
'edit_item' => __("Edit This Location"),
'new_item' => __("New Location"),
'view_item' => __("View Location"),
'search_items' => __("Search in Locations"),
'uploaded_to_this_item' => __("Used for image for this Location"),
'featured_image' => __("Location Image"),
'set_featured_image' => __("Set Location Image"),
'remove_featured_image' => __("Remove Location Image"),
'use_featured_image' => __("Use Location Image"),
'not_found' => __('No Locations'),
'not_found_in_trash' => __('No Locations found in Trash')
),
'public' => true,
'has_archive' => true,
'menu_icon' => 'dashicons-store',
'supports' => array('title','author','thumbnail','editor'),
'rewrite' => array('slug' => 'locations'),
)
);
}
function rt_rewrite_flush() {
// First, we "add" the custom post type via the above written function.
// Note: "add" is written with quotes, as CPTs don't get added to the DB,
// They are only referenced in the post_type column with a post entry,
// when you add a post of this CPT.
rt_custom_post();
// ATTENTION: This is *only* done during plugin activation hook in this example!
// You should *NEVER EVER* do this on every page load!!
flush_rewrite_rules();
}
register_activation_hook( __FILE__, 'rt_rewrite_flush' );

you'll just want to put your code function in and then change the rewrite rule to match your code!

**Remove WordPress Meta Boxes**
You have to make use of the function called `remove meta box`.
**Description:**
Removes a meta box or any other element from a particular post edit screen of a given post type. It can be also used to remove a widget from the dashboard screen.
>
> Steps to remove the meta box from WordPress Dashboard:
>
>
>
When removing WordPress meta boxes, I’ve seen it done in a number of different ways two of which are often done via JavaScript. Though this is functional for many, client-side solutions aren’t always great especially as it relates to accessibility.
On top of that, hiding things via JavaScript is kind of a hack – the visibility of elements should often be set in terms of CSS and it will likely cause a little bit of a flicker when the element is being hidden while the DOM loads.
Anyway, the two ways I’ve often seen it done is when:
Developers look for the check boxes under the Screen Options and then trigger the click event.
Developers sniff out the meta boxes ID and then use `jQuery’s hide()` method to hide the meta boxes from the page.
Sure, these work, but you’re still faced with the challenges of accessibility and with the fact that you’re modifying something that should probably be done via CSS.
Unless a hook exists.
And that’s really the mentality that we, as WordPress developers, should have whenever we’re attempting to introduce, remove, or modify anything as it relates to WordPress both in the dashboard and on the front-end.
Specifically, we need to ask ourselves:
Given what I need to do, is there a hook that makes this available?
And this is this case (and many, many cases), there is. We can take advantage of the `default_hidden_meta_boxes` hook.
**Using The Hook**
The function accepts two arguments:
1. An array of meta boxes that should be hidden
2. The current screen being displayed
This allows us to modify the existing array of hidden meta boxes (or create our own) and only trigger it on specific screen’s, as well.
So let’s say that we have a custom post type called `acme_post_type` and we want to hide the Categories, Author, Post Excerpt, and Slug meta box.
```
<?php
add_action( 'default_hidden_meta_boxes', 'acme_remove_meta_boxes', 10, 2 );
/**
* Removes the category, author, post excerpt, and slug meta boxes.
*
* @since 1.0.0
*
* @param array $hidden The array of meta boxes that should be hidden for Acme Post Types
* @param object $screen The current screen object that's being displayed on the screen
* @return array $hidden The updated array that removes other meta boxes
*/
function acme_remove_meta_boxes( $hidden, $screen ) {
if ( 'acme_post_type' == $screen->id ) {
$hidden = array(
'acme_post_type_categorydiv',
'authordiv',
'postexcerpt',
'slugdiv'
);
}
return $hidden;
}
```
First, the code checks to see if we’re on the screen for the custom post type. If so, then we define a new array that includes the IDs of the meta boxes that we want to hide. After that, we the array to WordPress and the end-result of the function will be that the specified meta boxes will be hidden from view.
In terms of getting the ID of the meta boxes that you want to hide, you can use the Developer Tools of your preferred browser to inspect the elements on the page.
>
> Another Example of how to remove the meta box in WordPress.
>
>
>
```
// REMOVE POST META BOXES
function remove_my_post_metaboxes() {
remove_meta_box( 'authordiv','post','normal' ); // Author Metabox
remove_meta_box( 'commentstatusdiv','post','normal' ); // Comments Status Metabox
remove_meta_box( 'commentsdiv','post','normal' ); // Comments Metabox
remove_meta_box( 'postcustom','post','normal' ); // Custom Fields Metabox
remove_meta_box( 'postexcerpt','post','normal' ); // Excerpt Metabox
remove_meta_box( 'revisionsdiv','post','normal' ); // Revisions Metabox
remove_meta_box( 'slugdiv','post','normal' ); // Slug Metabox
remove_meta_box( 'trackbacksdiv','post','normal' ); // Trackback Metabox
}
add_action('admin_menu','remove_my_post_metaboxes');
```
Place the following code in your functions file `(Appearance > Editor > Theme Functions – functions.php)`.
Placing that code should remove all the meta boxes below the post editor and give you a nice, clean look.

In your custom templates, First you have to fetch all terms for your custom post type.
You can use [get\_terms](https://developer.wordpress.org/reference/functions/get_terms/) to retrive terms in taxonomy
If you are using wordpress prior to 4.5
```
$terms = get_terms( 'competition' , array(
'hide_empty' => false
) );
```
OR if you are using wordpress prior to 4.5.0 or later
```
$terms = get_terms( array(
'taxonomy' => 'competition',
'hide_empty' => false,
) );
```
Next Build Term name lists:
```
$termNames = array();
$count = count( $terms );
if ( $count > 0 ) {
foreach ( $terms as $term ) {
$termNames[] = $term->name;
}
}
```
Next loop trough each terms and query posts for the current terms & then run the loop:
```
foreach($termNames as $termName) :
$args = array(
'post_type' => 'football_fixture',
'competition' => $termName,
'order' => 'ASC',
);
query_posts( $args );
if(have_posts()): ?>
<div class="<?php echo $col; ?>">
<h2><?php echo $termName; ?></h2>
<?php while(have_posts()): the_post(); ?>
<div id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
<?php
$id = get_the_ID();
$date = rwmb_meta( 'pb_match_date','', $post->ID);

I have a theme which appears to have broken previewing posts. When I preview a page/post I get a 404 error.
If I change to another theme previews work fine again so it must be something in this theme.
I can't work out when/if I would have broken previews. Going through my filters and actions I can't see anything obvious.
Has anyone had a similar problem/ What did it turn out to be?

I found the answer.
It was only for post-formats on pages. The issue was that I needed to also register the taxonomy `post_format` on pages as well in the init action.
I have updated the wiki page to reflect this.
<https://codex.wordpress.org/Post_Formats#Adding_Post_Type_Support>
```
// add post-formats to post_type 'page'
add_action('init', 'my_theme_slug_add_post_formats_to_page', 11);
function my_theme_slug_add_post_formats_to_page(){
add_post_type_support( 'page', 'post-formats' );
register_taxonomy_for_object_type( 'post_format', 'page' );
}
```

The value of the field it is checking is '25000' and I want to check that the value in the variable is less than or equal to this meta field.
This is working fine in the most part for any number above 10000 but anything below this it doesn't bring the results back.
I am trying to figure out what the issue is here, any input will be greatly appreciated.
The code is as follows:
```
$args = array(
'post_type' => 'loan-offers',
'meta_query' => array(
array(
'key' => 'amount',
'value' => $amount,
'compare' => '>='
),
array(
'key' => 'time',
'value' => $months,
'compare' => '>='
)
));
$custom_query = new WP_Query($args);
```
|
In order to deliver the amount variable to be less than 25000 you need to check the query with the operator called `<=` but you have tested it with `>=` in your query.
**Note:** There are several comparison operators available
```
= equals
!= does not equal
> greater than
>= greater than or equal to
< less than
<= less than or equal to
```
>
> But in your query you have misjudged the query and used. You have to use `<=` rather you have used `>=`
>
>
>
1. `<=` - Less than or Equal to
2. `>=` - Greater than or Equal to
>
> Usage of relation is appreciated in the Meta Query since without specifying the relation you are not supposed to mix the array of parameters that is given to the query for execution
>
>
>
```
$args = array(
'post_type' => 'loan-offers',
'meta_query' => array(
relation => 'AND', // This can be AND / OR depending on your choice
array(
'key' => 'amount',
'value' => $amount,
'compare' => '<='
),
array(
'key' => 'time',
'value' => $months,
'compare' => '>='
)
));
```
`LIKE` and `NOT LIKE` are `SQL operators` that let you add in wild-card symbols, so you could have a meta query that looks like this:
```
array(
'key' => 'name',
'value' => 'Pat',
'compare' => 'LIKE'
)
```
>
> Get Posts Within a Given Range of Numeric Meta Values
>
>
>
```
// the loan-offers is more than 10000 and less than 25000
$rd_args = array(
'post_type' => 'loan-offers',
'meta_query' => array(
array(
'key' => 'amount',
'value' => array( 10000, 25000 ),
'type' => 'numeric',
'compare' => 'BETWEEN'
)
)
);
$rd_query = new WP_Query( $rd_args );
```
You can use BETWEEN operator for getting the output as required by you.

You have made the mistake in getting the post link in your code.
**Missing**

Since your posts is behaving in the normal method you need to make the following changes.
1. Remove the `get_permalink()` from the code
2. Remove the echo tag in roder to display the permalink
Replace your code with the current one.
**Wherever you have used**
```
<?php echo get_permalink($post->ID); ?>
```
**Replace it with**
```
<?php the_permalink(); ?>
```
And your final code will look like as follows.

In my wordpress theme i m trying to print multiple `custom fields` of posts with ajax. First i get `title` of post with ajax live search correctly, now need to show post data after click on any post title.
After `Click` on any `title` in live search it show custom field for that post on same page??
**HTML:**
```
<h2><a href="#" name="metakey" id="metakey"><?php the_title();?></a></h2>
<div id="viewspec"> Meta key result here </div>
```
**Funtion:**
```
<?php
add_action('wp_ajax_data_fetchmeta' , 'data_fetchmeta');
add_action('wp_ajax_nopriv_data_fetchmeta','data_fetchmeta');
function data_fetchmeta(){
$the_query = new WP_Query( array( 's' => esc_attr( $_POST['metakey'] ), 'post_type' => 'post' ) );
if( $the_query->have_posts() ) :
while( $the_query->have_posts() ): $the_query->the_post(); ?>
<p>
<?php echo get_post_meta( get_the_ID(), 'brand', true );?>
<?php echo get_post_meta( get_the_ID(), 'price', true );?>
<?php echo get_post_meta( get_the_ID(), 'cpu', true );?>
<?php echo get_post_meta( get_the_ID(), 'ram', true );?>
</p>
<?php endwhile;
wp_reset_postdata();
endif;
die();
}
?>
```
**Script:**
```
<script type="text/javascript">
function h2 a{
jQuery.ajax({
url: '<?php echo admin_url('admin-ajax.php'); ?>',
type: 'post',
data: { action: 'data_fetchmeta', metakey: jQuery('#metakey').onclick() },
success: function(data) {
jQuery('#viewspec').html( data );
}
});
}
</script>
```
**AJAX live search: working**
```
<input type="text" name="keyword" id="keyword" onkeyup="fetch()"></input>
<div id="datafetch"> Search result here </div>
<?php
// add the ajax fetch js
add_action( 'wp_footer', 'ajax_fetch' );
function ajax_fetch() {
?>
<script type="text/javascript">
function fetch(){
jQuery.ajax({
url: '<?php echo admin_url('admin-ajax.php'); ?>',
type: 'post',
data: { action: 'data_fetch', keyword: jQuery('#keyword').val() },
success: function(data) {
jQuery('#datafetch').html( data );
}
});
}
</script>
<?php
}
// the ajax function
add_action('wp_ajax_data_fetch' , 'data_fetch');
add_action('wp_ajax_nopriv_data_fetch','data_fetch');
function data_fetch(){
if ( esc_attr( $_POST['keyword'] ) == null ) { die(); }
$the_query = new WP_Query( array( 'posts_per_page' => -1, 's' => esc_attr( $_POST['keyword'] ), 'post_type' => 'post' ) );
if( $the_query->have_posts() ) :
while( $the_query->have_posts() ): $the_query->the_post(); ?>
<h2><a href="#" name="metakey" id="metakey"><?php the_title();?></a> </h2>
<?php endwhile;
wp_reset_postdata();
endif;
die();
}
```

I'm not sure Why you used loop to display your post meta. and you code are all ok but you have to change little-bit.
***Q***. *Why you used inline script ? On my opinion you should used external script file to do this.*
anyway that's not the main issue here. In order to work with click function with ajax generate conten. You have to bind click function proper way otherwise it not will work.
Here is an example, but I'm useing external js file for this and so you just have to register.
```
/**
* Add js file with Enqueues scripts.
*/
function wpse_scripts() {
wp_enqueue_script( 'wpse-ajax-init', get_stylesheet_directory_uri() . '/js/wpse-ajax-init.js', array( 'jquery' ), '1.0', true );
wp_localize_script( 'wpse-ajax-init', 'ajaxwpse', array(
'ajaxurl' => admin_url( 'admin-ajax.php' )
));
}
add_action( 'wp_enqueue_scripts', 'wpse_scripts' );
```
And now change you title markup that you fetch post title.
```
// the ajax function
add_action('wp_ajax_data_fetch' , 'data_fetch');
add_action('wp_ajax_nopriv_data_fetch','data_fetch');
function data_fetch(){
if ( esc_attr( $_POST['keyword'] ) == null ) { die(); }
$the_query = new WP_Query( array( 'posts_per_page' => -1, 's' => esc_attr( $_POST['keyword'] ), 'post_type' => 'post' ) );
if( $the_query->have_posts() ) :
while( $the_query->have_posts() ): $the_query->the_post(); ?>
<h2><a href="#" name="metakey" id="<?php the_ID(); ?>"><?php the_title();?></a> </h2>
<?php endwhile;
wp_reset_postdata();
endif;
die();
}
```
I'm here just changed `<h2><a href="#" name="metakey" id="metakey"><?php the_title();?></a> </h2>` to `<h2><a href="#" name="metakey" id="<?php the_ID(); ?>"><?php the_title();?></a> </h2>` because you need to grab the ID of the title dynamically.
After doing that add below code on your `wpse-ajax-init.js` that you just register and hook with `admin-ajax.php`.
```
(function ($) {
$("#datafetch").on('click', 'a', function(e) {
e.preventDefault();
$('#keyword').delay(100).attr('value', '');
$(this).delay(100).hide();
$.ajax({
url: ajaxwpse.ajaxurl,
type: 'post',
data: {
action: 'data_fetchmeta',
ID: $(this).attr('id')
},
success: function(data) {
$('#viewspec').html( data );
}
});
});
})(jQuery);
```
And finally changed your `data_fetchmeta()` function query like this
```
add_action('wp_ajax_data_fetchmeta' , 'data_fetchmeta');
add_action('wp_ajax_nopriv_data_fetchmeta','data_fetchmeta');
function data_fetchmeta(){
$ID = esc_attr( $_POST['ID'] ); ?>
<p>
<?php echo get_post_meta( $ID, 'brand', true );?>
<?php echo get_post_meta( $ID, 'price', true );?>
<?php echo get_post_meta( $ID, 'cpu', true );?>
<?php echo get_post_meta( $ID, 'ram', true );?>
</p>
<?php die();
}
```
You can see, I just grab the dynamic id and used to display post meta.
Hope it make sense to you.

We have a situation where the users (children) keep not forgetting their password but making trivial mistakes while trying to login.
As per question they should be first redirected to page e.g. id=5 with instructions like:
>
> Please go back and:
>
> Activate your cookies
>
> Check if the correct language is on your keyboard
>
> Ask your mother to log you in
>
> etc...
>
> If none of the above works please click here (<http://oursite.com/wp-login.php?action=lostpassword>) to ask for a new password
>
>
>
So, the lostpassword link on the login page should redirect to the existing page with the custom message/instructions **and then**, the link on the page to the actual lostpassword link.
*PS: I believe that the lately introduced [lostpassword\_post](https://developer.wordpress.org/reference/hooks/lostpassword_post/) hook could be useful.*
|
This is straightforward.
1. Hook on init to detect the lostpassword page
2. If the user is not coming from your instructions page (which we defined by adding extra query parameter) he'll be redirected to your custom page
3. In your custom page add the link to lost password page including the extra parameter we set to skip the redirection.
```
add_action( 'init', 'lostpassword_instructions' );
function lostpassword_instructions() {
global $pagenow;
if ( $pagenow == 'wp-login.php' &&
isset( $_REQUEST[ 'action' ] ) &&
$_REQUEST[ 'action' ] == 'lostpassword' &&
! isset( $_REQUEST[ 'skip' ] )
) {
exit( wp_redirect( 'http://domain.com/lost-password-instructions' ) );
}
}
```
Now on your custom page, something like that should work:
```
$url = 'http://domain.com/wp-login.php?action=lostpassword&skip=true';
```

<p>Wordpress 4.4 indroduced a way to display the genitive case of a months name for specific locale by using the function <code>date_i18n</code> (<a href="https://core.trac.wordpress.org/ticket/11226#comment:32" rel="nofollow">https://core.trac.wordpress.org/ticket/11226#comment:32</a>) which is filtered by <code>wp_maybe_decline_date()</code> (<a href="https://core.trac.wordpress.org/browser/tags/4.6/src/wp-includes/functions.php#L172" rel="nofollow">https://core.trac.wordpress.org/browser/tags/4.6/src/wp-includes/functions.php#L172</a>). Even though both my locale (el) and the translation of the string "decline months names: on or off" in my el.po file are correct, the genitive case of the months name is not working. So with this: <code>echo date_i18n( 'j F Y', strtotime( '2016/9/20' ) );</code> I got the date with the month name in nominative case.</p>
<p>Any ideas? Thanks in advance!</p>

Wordpress 4.4 indroduced a way to display the genitive case of a months name for specific locale by using the function `date_i18n` (<https://core.trac.wordpress.org/ticket/11226#comment:32>) which is filtered by `wp_maybe_decline_date()` (<https://core.trac.wordpress.org/browser/tags/4.6/src/wp-includes/functions.php#L172>). Even though both my locale (el) and the translation of the string "decline months names: on or off" in my el.po file are correct, the genitive case of the months name is not working. So with this: `echo date_i18n( 'j F Y', strtotime( '2016/9/20' ) );` I got the date with the month name in nominative case.
Any ideas? Thanks in advance!

Although, in my wp your `echo` displayed correctly (so maybe double check that you use the correct locale and that "decline months names: on or off" is translated as "on" in your locale), you can *"force"* genitive case, by making a generic wrap function based on the `wp_maybe_decline_date()`.
I have tested and used this, in order to overcome the `wp_maybe_decline_date()` regex that ,matches formats like `'j F Y'` or `'j. F'`, while I wanted to use `'l j F Y'`
Example use case:
In our theme `functions.php` we define the wrapper function like:
```
/**
* [multi_force_use_genitive_month_date]
* Call this to force genitive use case for months in date translation
* @param string $date Formatted date string.
* @return string The date, declined if locale specifies it.
*/
function multi_force_use_genitive_month_date( $date ) {
global $wp_locale;
// i18n functions are not available in SHORTINIT mode
if ( ! function_exists( '_x' ) ) {
return $date;
}
/* translators: If months in your language require a genitive case,
* translate this to 'on'. Do not translate into your own language.
*/
if ( 'on' === _x( 'off', 'decline months names: on or off' ) ) {
// Match a format like 'j F Y' or 'j. F'
$months = $wp_locale->month;
$months_genitive = $wp_locale->month_genitive;
foreach ( $months as $key => $month ) {
$months[ $key ] = '# ' . $month . '( |$)#u';
}
foreach ( $months_genitive as $key => $month ) {
$months_genitive[ $key ] = ' ' . $month . '$1';
}
$date = preg_replace( $months, $months_genitive, $date );
}
// Used for locale-specific rules
$locale = get_locale();
return $date;
}
```
Then, in our template file where we want the genitive case to appear, we wrap the `date_i18n()`, like:
```
<?php echo multi_force_use_genitive_month_date( date_i18n( 'l j F Y' ) ); ?>
```
Hope this helps.

<p>I have a plugin that adds the following action which among other things sends out a registration mail when a new user is added:</p>
<pre><code>add_action('um_post_registration_approved_hook', 'um_post_registration_approved_hook', 10, 2);
</code></pre>
<p>I would like to remove this action, so I can add it again with some additional checks in the called function. I have tried the following, but can't get it to work:</p>
<pre><code>add_action( 'um_post_registration_approved_hook', 'remove_my_action', 11 );
function remove_my_action(){
remove_action('um_post_registration_approved_hook', 'um_post_registration_approved_hook', 10, 2);
}
</code></pre>
<p>Any ideas?</p>
<p><strong>EDIT</strong></p>
<p>Turns out I had the priority wrong, thanks! I am now able to remove the action and register a new one instead. However, I'm now having some problems with that. This is what I've unregistered:</p>

function um_post_registration_approved_hook($user_id, $args){

}

<p>I have then registered the following instead:</p>

<p>Which is simply another version of the original approve()-function, with the mail notification removed.

The original file is here, with the approve()-function defined from line 941: <a href="http://pastebin.com/FknrcxzM" rel="nofollow">http://pastebin.com/FknrcxzM</a></p>
<p>Does my problem make sense? And can I hook into the class instead of the function? - Don't really know the correct approach here..</p>

You want:
```
remove_action('um_post_registration_approved_hook', 'um_post_registration_approved_hook', 10, 2);
```
... to run after the original `add_action`, but before the action triggers the function `um_post_registration_approved_hook`
The easiest way to do this, but I haven't tested it, might be to just give your removal an earlier priority on the same hook:
```
add_action( 'um_post_registration_approved_hook', 'remove_my_action', 9 );
function remove_my_action(){
remove_action('um_post_registration_approved_hook', 'um_post_registration_approved_hook', 10, 2);
}
```
This is what you were trying, but the priority was the wrong way around. `11` runs after `10`.

This depends on what is it that you are trying to do/use. In theory the protocol used to communicate with memcached server is not very complex and can be implemented in PHP, and therefor as a plugin. In practice you might want to prevent collisions of multiple processes writing at the same time to the cahce which will most likely require the access to the multi tasking API of the OS, something that is not built-in in the default PHP modules and will require you to use additional modules in any case. (there is also probably some performance argument that can be made here between running C and PHP code, but I am not sure how important it is).
Having it as module also let you as the server admin "break out" of whatever restrictions you put on the PHP code in the php.ini and other setting files (in theory you can block the ability of the PHP application to connect anywhere, although I never heard of anyone doing that)

<p>I need to run a query (via <code>functions.php</code>) and find all posts with a certain tag and add those posts to a category.</p>
<p><strong>example:</strong> </p>
<p>Find all posts with tag <strong>"car"</strong> and add them to category <strong>"transportation"</strong>.</p>
<p><strong>EDIT:</strong> STILL NOT WORKING, BUT...</p>
<p>This is what I have so far thanks to <a href="https://wordpress.stackexchange.com/questions/240970/add-category-to-posts-with-tag-wordpress#240973">@benoti's answer</a> (bellow):</p>
<pre><code>$args = array(
'post_type'=>'post',
'tax_query' => array(
'taxonomy' => 'tag',
'field' => 'slug',
'terms' => 'car',
),
);
$posts = get_posts($args);
foreach ($posts as $post) :
//do stuff
$cat_id = 1669; // the ID of category transportation
$append = true; // If true, terms will be appended to the object. If false, terms will replace existing terms
// make some verif that's better
wp_set_object_terms($post->ID, $cat_id, 'category', $append);
endforeach;
</code></pre>
<p>...but it's not working.</p>
<p><strong>Also, to clarify</strong>: </p>
<p>I need to add a category to all posts that contain the <strong>"car "</strong> tag, but I do not know in what category they (the posts) are in.</p>
<p>How can I safely do this without break my site?</p>

I need to run a query (via `functions.php`) and find all posts with a certain tag and add those posts to a category.
**example:**
Find all posts with tag **"car"** and add them to category **"transportation"**.
**EDIT:** STILL NOT WORKING, BUT...
This is what I have so far thanks to [@benoti's answer](https://wordpress.stackexchange.com/questions/240970/add-category-to-posts-with-tag-wordpress#240973) (bellow):
```
$args = array(
'post_type'=>'post',
'tax_query' => array(
'taxonomy' => 'tag',
'field' => 'slug',
'terms' => 'car',
),
);
$posts = get_posts($args);
foreach ($posts as $post) :
//do stuff
$cat_id = 1669; // the ID of category transportation
$append = true; // If true, terms will be appended to the object. If false, terms will replace existing terms
// make some verif that's better
wp_set_object_terms($post->ID, $cat_id, 'category', $append);
endforeach;
```
...but it's not working.
**Also, to clarify**:
I need to add a category to all posts that contain the **"car "** tag, but I do not know in what category they (the posts) are in.
How can I safely do this without break my site?
|
This is just an example to get all posts in the category transportation with the tag car :
```
$args = array(
'post_type'=>'post',
'tax_query' => array(
'relation' => 'AND',
array(
'taxonomy' => 'category',
'field' => 'slug',
'terms' => array( 'transportation' ),
),
array(
'taxonomy' => 'tag',
'field' => 'slug',
'terms' => array( 'car' ),
'operator' => 'IN',
),
);
$posts = get_posts($args);
```
**EDIT :** for a simple tax\_query
```
'tax_query' => array(
array(
'taxonomy' => 'tag',
'field' => 'slug',
'terms' => 'car'
)
)
```
You can grab more details and it for your case here <https://codex.wordpress.org/Class_Reference/WP_Query#Category_Parameters>
This will not get the posts tag 'car' and add category 'transportation' to them, but you need first to get posts.
With this result you can loop through it and use `wp_set_object_terms( $object_id, $terms, $taxonomy, $append );` in this loop to add your category to the tagged posts.
```
foreach($posts as $post){
$append = true; // If true, terms will be appended to the object. If false, terms will replace existing terms
// make some verif that's better
wp_set_object_terms($post->ID, 'transportation', 'category', $append);
}
```
the best it to read <https://codex.wordpress.org/Function_Reference/wp_set_object_terms>
I hope you get it !

I created an input field in general - settings. It's in a plugin for a for a local ngo network site.
It looks like this, and it works great.
```
$ngob_sitelist_slug = new ngob_sitelist_slug();
class ngob_sitelist_slug {
function ngob_sitelist_slug( ) {
add_filter( 'admin_init' , array( &$this , 'ngob_register_slug' ) );

function ngob_slug_html() {
$value = get_option( 'sitelist_slug', '' );
echo '<input type="text" id="sitelist_slug" name="sitelist_slug" value="' . $value . '" />';
}
}
```
However I only want it to be created for the network (main) site on a WPMU installation.
So I did this;
```
// Get site id
$blog_id = get_current_blog_id();
// Check if we are on network site
if( is_main_site( $blog_id ) ) {
$ngob_sitelist_slug = new ngob_sitelist_slug();
class ngob_sitelist_slug {
function ngob_sitelist_slug( ) {
add_filter( 'admin_init' , array( &$this , 'ngob_register_slug' ) );
}
function ngob_register_slug() {
register_setting( 'general', 'sitelist_slug', 'esc_attr' );
add_settings_field('sitelist_slug', '<label for="sitelist_slug">'.__('Slug för site-lista' , 'ngo-branding' ).'</label>' , array(&$this, 'ngob_slug_html') , 'general' );
}
function ngob_slug_html() {
$value = get_option( 'sitelist_slug', '' );
echo '<input type="text" id="sitelist_slug" name="sitelist_slug" value="' . $value . '" />';
}
}
}
```
However, I get this error when reloading the page:
```
Fatal error: Uncaught Error: Class 'ngob_sitelist_slug' not found...(shortened the output, since it's mostly path:s)
```
Why is that? Im fairly novis on classes to start with, but when *not* on network site, the class doesn't get executed, so no problem, as expected.
But when *on* network site, I get above error..
How to mend this so I can get that input field, but only on the main (network) site?
I don't fully understand what the problem is, and it seems hard to find anything on google about this. I guess you can't wrap a class in an if? But why not, and mostly, how to solve the issue?

How are you invoking `ngob_sitelist_slug`?
I'm gonna guess that you are doing something like `$my_class = new ngob_sitelist_slug;`. Doing it this way would require that your class have a [constructor](http://php.net/manual/en/language.oop5.decon.php). if it doesn't, you'll get an error.
You could still call your class methods statically:
```
$my_thing = ngob_sitelist_slug::my_method();
```
Though technically you should add the `static` keyword to your methods in this case.
Also I see that in your case you are using $this, so you really need a constructor.
EDIT:
I now realize you do have a constructor - albeit a deprecated one.

'post_type' => 'entity',
'posts_per_page' => 20,
'meta_query' => array(
array(
'key' => 'entity_person_profile_type',
'value' => $term->term_id,
'compare' => '='
)
),
'orderby' => 'meta_value_num',
'meta_key' => 'entity_person_relevance',
'order' => 'DESC',
'paged' => $paged
)
);
</code></pre>
<p>I'd like to show also the posts which doesn't have the custom field already set. </p>

```
I'd like to show also the posts which doesn't have the custom field already set.

Adding a css rule for #wpadminbar:
```
transform: translate3d(0,0,0);
background: black;
width: 100%;
```
Makes the bar appear and
I added z-index: 0; to .mdl-layout\_\_header to make the dropdowns appear.
Not the prettiest.

you should remove:
```
require('http://solutionsagencia.com.br/comparasaude/wp-load.php');
```
and use:
```
require(ABSPATH.'wp-includes/pluggable.php');
```
p.s. I advice you, these executions should be hooked in 'init', like:
```
add_action('init', function(){
$para = "[email protected]";
$assunto = "Assunto" . $nome;
$conteudo =
"<b>Nome:</b> {$nome}" .
"<b>Email:</b> {$email}" .
$headers = array(

);
$status = wp_mail( $para, $assunto, $conteudo );
remove_filter( 'wp_mail_content_type', 'set_html_content_type' );
if ( $status ){
echo "sucesso";
} else {
}

I've created some additional tables for a plugin I'm developing and need to add indexes to these tables.
What's the WordPress way to do this?
Using [`dbDelta()`](https://developer.wordpress.org/reference/functions/dbdelta/) doesn't seem to be working, and I'm not seeing any error in the logs.
|
You can execute *arbitrary* SQL statements with [wpdb::query()](https://developer.wordpress.org/reference/classes/wpdb/query/), including Data Definition Statements, e.g.
```
function
create_index ()
{
global $wpdb ;
$sql = "CREATE INDEX my_index ON {$wpdb->prefix}my_table (my_column)" ;
$wpdb->query ($sql) ;
return ;

You can execute *arbitrary* SQL statements with [wpdb::query()](https://developer.wordpress.org/reference/classes/wpdb/query/), including Data Definition Statements, e.g.
```
function
create_index ()
{
global $wpdb ;
$sql = "CREATE INDEX my_index ON {$wpdb->prefix}my_table (my_column)" ;
$wpdb->query ($sql) ;
return ;
}
```
**Note:** Because `$wpdb->query()` can execute *arbitrary* SQL, if the statement you pass to it contains **ANY** user input, then you should use [wpdb::prepare()](https://developer.wordpress.org/reference/classes/wpdb/prepare/) to protect against SQL Injection attacks.
But this raises the question: how did you create your plugin-specific tables? "Manually" or programmatically? If programmatically, did you not use `$wpdb->query()`? If you did it "manually", then you really should create the tables (and their indexes) upon plugin activation.

I have the following problem:
I have created a custom post type `matratze` and currently besides the custom posts no other posts exist. Hence, nothing is being displayed under the recent posts.
The custom post type looks like the following:
[custom post]

[main homepage]
I tried the following:
```
add_filter( 'pre_get_posts', 'my_get_posts' );

Wordpress provides [`wp_get_recent_posts()`](https://developer.wordpress.org/reference/functions/wp_get_recent_posts/) function to retrive a number of recent posts from any post types. you can pass your custom post type as an arguments to retrieve recent posts lists.
```
$args = array(
'numberposts' => '5',
'orderby' => 'post_date',
'order' => 'DESC',
'post_type' => 'matratze',
'post_status' => 'publish'
);
$recent_posts = wp_get_recent_posts( $args );
```
**Wordpress Core Recent Posts widget does not provide feature to list posts from custom post type. If you want to list post using Widget, you can use [Posts in Sidebar](https://wordpress.org/plugins/posts-in-sidebar/) Plugin.** This plugins i very powerful and provides you many options to show posts based on many criteria including recent posts from custom post types.
**UPDATE:**
Here is code you can use for your specific case:
You are using Tab Widget to display recent posts which uses WP\_Query. So you can use pre\_get\_posts to set post type filter.
```
function filter_recent_get_posts($query) {
if (isset($_POST['tab']) && ($_POST['tab'] == 'recent')) {
$query->set('post_type', 'matratze');
}
}
add_action( 'pre_get_posts', 'filter_recent_get_posts' );
```

Because you are ordering *only* by `menu_order`, rather than `menu_order post_title`. In fact, you can just get rid of your `sort_*` arguments as `wp_list_pages` will output the correct natural order by default.

<p>I want to create a child theme for TwentyFifteen theme, which will customize a lot of things, including translation. When I install WordPress in my language (Farsi), it includes TwentyFifteen language files in <code>wp-content/languages/themes</code></p>
<p>So when I create a <code>languages</code> folder in my child theme and add customized language files to it and add <code>load_theme_textdomain( 'twentyfifteen', get_stylesheet_directory() .

What can I do to override those files?</p>

So when I create a `languages` folder in my child theme and add customized language files to it and add `load_theme_textdomain( 'twentyfifteen', get_stylesheet_directory() . '/languages' )` to my child theme's `functions.php` my customized language files do not load and instead the files in `wp-content/languages/themes` load. What can I do to override those files?
|
Since WP 4.6 `load_theme_textdomain()` (and consequently `load_child_theme_textdomain()`) will give priority to .mo files downloaded from WP's online translation platform (translate.wordpress.org). Due to some new code ([here, on line 769](https://core.trac.wordpress.org/browser/tags/4.6/src/wp-includes/l10n.php#L755)) these functions will completely ignore your local .mo files if the textdomain is found in the general *languages/* directory.
You can, however, use the more basic `load_textdomain()` function to directly load your .mo file and override strings from the original domain, like this:
```
$domain = 'textdomain-to-override';
$path = get_stylesheet_directory() . '/languages/'; // adjust to the location of your .mo file
$locale = apply_filters( 'theme_locale', get_locale(), $domain );
load_textdomain( $domain, $path . $locale . '.mo' );
```

<p>Is it possible to customize AJAX response when using filters such as <code>check_admin_referer</code> and <code>check_ajax_referer</code> ?</p>
<p>I've done some tweaks (with those filters) to prevent users from deleting some terms that are really important and MUST not be deleted. But it keeps telling me "unknown error" which is far from being clear.</p>
<p>Any hint would be cool.</p>
<p>For now I'm using wp_die( 'This term cannot be deleted' ) and I wonder how to inject this message in AJAX response.</p>

Is it possible to customize AJAX response when using filters such as `check_admin_referer` and `check_ajax_referer` ?
I've done some tweaks (with those filters) to prevent users from deleting some terms that are really important and MUST not be deleted. But it keeps telling me "unknown error" which is far from being clear.
Any hint would be cool.
For now I'm using wp\_die( 'This term cannot be deleted' ) and I wonder how to inject this message in AJAX response.

Wait for WordPress 4.7 on 6th December. It has this almost built-in.
If I got it right, then you'll want to prevent some terms from deletion.
I already made a snippet for that which works with WP 4.7
```
add_filter(
'user_has_cap',
function ( $allcaps, $caps, $args ) {
if ( ! isset( $args[0] ) || 'delete_term' != $args[0] ) {
// not the deletion process => ignore
return $allcaps;
}
$term = get_term( $args[2] );
// HERE YOU'LL LIKE TO PUT YOUR LOGIC INSTEAD OF THIS:
if ( $term->count <= 0 ) {
return $allcaps;
}
// for all other cases => reject deletion
return [ ];
},
10,
3
);
```

<p>I currently have a parent page with some child pages. I am able to list these child pages but would like to insert a custom li class. The <code>wp_list_pages</code> outputs <code><li class="page-item number"></li></code>. I would like for it to output <code><li class="hvr-underline"></li></code>. Here is the code I have so far:</p>
<pre><code>$children = wp_list_pages( 'title_li=&child_of='.$post->ID.'&echo=0' );
if ( $children) : ?>
<ul class="menu ">
<?php echo $children; ?>
</ul>
<?php endif;

<pre><code>header("Location: http://vader.com/saber.html");
exit();
</code></pre>
<p>but I wanted to replace <code>http://vader.com</code> with the site URL so this could be portable but after researching I didn't see a way to obtain the site URL without the connection and I per discussions I was told you want to do minimal modifications to the wp.config file.

One option is setting the site's URL in the `wp-config.php` file itself. This effectively overrides the `siteurl` option that's otherwise stored in the database, but it also means you can reference the URL without doing a query.
From [the Codex](https://codex.wordpress.org/Changing_The_Site_URL#Edit_wp-config.php):

After that, using code in a regular theme that checks the `siteurl` or `home` option will pull from the constant rather than the database (hence my note on the override above). But in your default error script, you can reference `WP_SITEURL` directly to build a redirect URL.

WordPress doesn't seem to like `$data`. Is there a way to do this with `wpdb`?

I see no reason to use wpdb for this, unless your table is in the Wordpress database. Also your code would be much clearer (and therefore less prone to errors) if you separate the fetching of the result into an array, and the processing of this array for transformation, from the generation of the final html output. Separate logic from presentation.
So, first put all data into an array in the standard way:
```
$query = ("SELECT * FROM titles WHERE `active` = 0 ORDER BY author, title");
$results_array = array();
$result = $mysqli->query($query);
while ($row = $result->fetch_assoc()) {
$results_array[] = $row;
}
```
The first row of this array, i.e. `$results_array[0]`, for example, will be the array `('Title' => 'Title 1','Author' => 'j cool', 'Device1' => 'inputA',...)`
**Edit**: Alternatively, if you insist on using the wpdb class, replace the above code by:
```
$mydb = new wpdb('user','password','database','server');
$results_array = $mydb->get_results("SELECT * FROM titles WHERE `active` = 0 ORDER BY author, title",ARRAY_A);
```
`$results_array` has the same content with both approaches. The rest of the code doesn't change.
**End edit**
You want to obtain from `$results_array` an associative array that associates to each Author a table mapping input to devices, like this:
```
array('j cool' => array('inputA' => array('Device1', 'Device2'),
'inputB' => array('Device3')),
'l maker' => array('inputA' => array('Device1'),
'inputB' => array('Device2'),
'inputC' => array('Device3')),
'm this' => ...)
```
The following code assumes you know all possible values of inputs in advance, and that these do not match exactly authors or titles.
```
$inputs = array('inputA','inputB','inputC');
$input_table = array();
foreach ($results_array as $row) {
$row_inputs = array();
foreach ($inputs as $in) {
//get all keys (devices) in $row that have input $in as value
$devices = array_keys($row,$in);
if (!empty($devices))
$row_inputs[$in] = $devices;
}
$input_table[$row['Author']] = $row_inputs;
}
```
This generates an array where each row, indexed by the Author, is an array like the example above. Now we add the title:
```
$final_table = array();
foreach ($results_array as $row) {
$final_table[] = array('Title' => $row['Title'],
'Author' => $row['Author'],
'Inputs' => $input_table[$row['Author']]);
}
```
Finally, display the resulting array in html:
```
$html = '';
//$html .= '<html><body>';
$html .= "<table>"; //add here code for table headers too
foreach ($final_table as $row) {
//first row for author
$html .= '<tr><td>'. $row['Title'] . '</td><td>' . $row['Author'] . '</td>';
foreach (array_keys($row['Inputs']) as $in) {
//output input names for this author
$html .= '<td>'.$in.'</td>';
}
$html .= '</tr><td></td><td></td>';
//second row for author, starting in third column
foreach ($row['Inputs'] as $in => $devices) {
$html .= '<td>'.implode(" ",$devices).'</td>';
}
$html .= '</tr>';
}
$html .= '</table>';
// $html .= </body></html>
echo $html;
```

I am currently looking into passing a single query into multiple widgets on a template without running multiple queries. The obvious goal is speed and efficiency.
I have a widget that will deliver specific aspects of the same object with different instances of the widget in the template. Widget instances are a **must**, but the object instance should remain unchanged. Is there a sweet spot in the template run of actions and filters I should look for in my widget?
For example, I want `object->title` to show in my widget at the top of the page, so I check that box and so to show in that area. Then I have another instance of the widget where I check `object->content` to show in that area.
That's very easy inside of the widget, however, very inefficient because I just ran two queries for the same object, because of my widgets being two different objects unto themselves.
How can my widget not attempt the same query twice in this situation? Will `get_queried_object` run a query for both of those widget instances?

I suggest to use the [Object Cache API](https://codex.wordpress.org/Class_Reference/WP_Object_Cache) or [Transients API](https://codex.wordpress.org/Transients_API), whatever fits better your needs.
A very quick example with object cache:
```
// helper function
function get_my_object() {
$object = wp_cache_get( 'my_object' );
if ( false === $object ) {
$args = array( .... );
$object = new WP_Query( $args );
wp_cache_set( 'my_object', $object );
}
return $object;
}
class cyb_my_widget extends WP_Widget {
function __construct() {
// ...
}
function widget( $args, $instance ) {
// ...
$object = get_my_object();
}
function update( $new_instance, $old_instance ) {
// ...
}
function form( $instance ) {
// ...
}
}

<p>I’m having a complex content issue. Each page can have multiple sections (unknown number), each section can have multiple containers, each container can have multiple content blocks (either 1, 2 or 3).</p>
<p>I’ve currently got a theoretical solution with shortcodes, but I would like to solve this with the UI if possible by providing wysiwyg editors for each content block.</p>
<p>Sections: There can be any number of sections (a realistic/acceptable maximum would be 10).
Containers: A section can contain any number of rows (a realistic/acceptable maximum would be 5).
Containers: A row must know how many columns it needs to contain.
Content blocks: A row can contain 1, 2 or 3 columns.</p>
<p>The shortcode solution looks something like this:</p>
<pre><code>[section id="summary"] //id is required but can be anything (no spaces)
[container blocks="1"] //row can have 1, 2 or 3 columns
[block]
.content-block
[/block]
[/container]
[/section]
[section id="find us"] //id is required but can be anything (no spaces)
[container blocks="3"] //row can have 1, 2 or 3 columns
[block]
.content-block
[/block]
[block]
.content-block
[/block]
[block]
.content-block
[/block]
[/container]
[/section]
[section id="team"] //id is required but can be anything (no spaces)
[container blocks="2"] //row can have 1, 2 or 3 columns
[block]
.content-block
[/block]
[block]
.content-block
[/block]
[/container]
[/section]
</code></pre>
<p>Does anyone have any suggestions on how I can go about this?</p>
<p>Thanks,
Josh</p>

This sounds to me like a perfect use of [Advanced Custom Fields "flexible content"](https://www.advancedcustomfields.com/resources/flexible-content/) feature to me. Flexible content fields allow you to define multiple layouts, and then add them to a page or post one by one, in any order or combination you need. Each layout can be a combination of text fields, images, wysiwyg editors, and other field types.
It's a brilliant UI on the client side, and easy to build a custom front-end in your template once you get the hang of it.
It's a premium plugin, but I've been building these kinds of interfaces for many years and it works really well. I haven't found anything else quite like it.

<p>I have a plugin which requires a style sheet for the widget. I am trying to register the stylesheet when the widget is created, however the style sheet is not being queued and the styles ignored. The code I am using follows, with commented lines demonstrating some other options I have tried:</p>
<p>organiser.php</p>
<pre><code>class Organiser extends WP_Widget {
...
public function widget( $args, $instance ) {
add_action( 'wp_enqueue_scripts', array('Organiser', 'register_plugin_styles') );
include(dirname(__FILE__)."/organiserWidget.php");
}
function register_plugin_styles() {
wp_register_style( 'organiserStyle', plugins_url( 'organiser/css/organiserStyle.css' ) );
wp_enqueue_style( 'organiserStyle' );
// wp_register_style( 'organiserStyle', plugin_dir_url( __FILE__ ) . 'css/organiserStyle.css' );
// wp_enqueue_style( 'organiserStyle', plugin_dir_url( __FILE__ ) . 'css/organiserStyle.css');

<p>But consider the case when I want to get list of posts and their thumbnails. One time I should call <code>http://example.com/wp-json/wp/v2/posts?items=id,title,featured_media</code> then I should call <code>http://example.com/wp-json/wp/v2/media/id</code> 10 times for each media id and then parse the results and get final url of media thumbnail. So it needs 11 request for get details of 10 post (one for list,10 for thumbnails).
Is it possible to get this results in one request?</p>

I'm using [wp-rest api](https://wordpress.org/plugins/json-rest-api/) to get posts information.
I also use [wp rest api filter items](https://github.com/bueltge/wp-rest-api-filter-items) to filter fields and summarize the result:
When I call `http://example.com/wp-json/wp/v2/posts?items=id,title,featured_media` it returns results like this:
```
[
{
"id": 407,
"title": {
"rendered": "Title 1"
},
"featured_media": 399
},
{
"id": 403,
"title": {
"rendered": "Title 2"
},
"featured_media": 401
}
]
```
The question is how can I generate featured media url using this id? By default calling `http://example.com/wp-json/wp/v2/media/401` returns a new json which have all details about url of different sizes of source image:
```
{
"id": 401,

But consider the case when I want to get list of posts and their thumbnails. One time I should call `http://example.com/wp-json/wp/v2/posts?items=id,title,featured_media` then I should call `http://example.com/wp-json/wp/v2/media/id` 10 times for each media id and then parse the results and get final url of media thumbnail. So it needs 11 request for get details of 10 post (one for list,10 for thumbnails).
Is it possible to get this results in one request?
|
Ah I just had this problem myself! And while `_embed` is great, in my experience it is very slow, and the point of JSON is to be fast :D
I have the following code in a plugin (used for adding custom post types), but I imagine you could put it in your theme's `function.php` file.
`php`
```
add_action( 'rest_api_init', 'add_thumbnail_to_JSON' );
function add_thumbnail_to_JSON() {
//Add featured image
register_rest_field(
'post', // Where to add the field (Here, blog posts. Could be an array)
'featured_image_src', // Name of new field (You can call this anything)
array(
'get_callback' => 'get_image_src',
'update_callback' => null,
'schema' => null,
)
);
}
function get_image_src( $object, $field_name, $request ) {
$feat_img_array = wp_get_attachment_image_src(
$object['featured_media'], // Image attachment ID
'thumbnail', // Size. Ex. "thumbnail", "large", "full", etc..
true // Whether the image should be treated as an icon.
);
return $feat_img_array[0];
}
```
Now in your JSON response you should see a new field called `"featured_image_src":` containing a url to the thumbnail.
Read more about modifying responses here:
<http://v2.wp-api.org/extending/modifying/>
And here's more information on the`register_rest_field` and `wp_get_attachment_image_src()` functions:
1.) <https://developer.wordpress.org/reference/functions/register_rest_field/>
2.) <https://developer.wordpress.org/reference/functions/wp_get_attachment_image_src/>
\*\*Note: Don't forget `<?php ?>` tags if this is a new php file!

To get with the time and improve my coding practices, I'm starting to implementing [namespaces](https://secure.php.net/manual/en/language.namespaces.php) in my own plugins moving forward since there are some advantages, [such as eliminating ambiguity](https://stackoverflow.com/q/5393108/6579923).
I found a [similar question](https://wordpress.stackexchange.com/q/193997/98212) to help me set up my plugin template which worked for me. However, I've since modified it slightly. This is my setup:

$class = str_replace( '\\', DIRECTORY_SEPARATOR, str_replace( '_', '-', strtolower($classname) ) );

# Check if the file exists
if ( file_exists( $path ) ) {

}
}
```

namespace PluginTemplate\admin;
class Plugin_Meta {
public function __construct() {
add_action( 'plugins_loaded', array($this, 'test' ) );

}
}
```
When I try to activate the plugin template for testing, I get the following error:
>

The problem is with your Autoloader set-up. You need to convert your Camelcase namespacese to dashes for locating files as per your current folder structure.
I have added convert function and updated your autoloader function.
In `wp-plugin-template/autoloader.php`:
```
<?php
spl_autoload_register( 'autoload_function' );
function autoload_function( $classname ) {
$class = str_replace( '\\', DIRECTORY_SEPARATOR, str_replace( '_', '-', strtolower(convert($classname)) ) );
# Create the actual file-path
$path = WP_PLUGIN_DIR . DIRECTORY_SEPARATOR . $class . '.php';
# Check if the file exists
if ( file_exists( $path ) ) {
# Require once on the file
require_once $path;
}
}
function convert($class){
$class = preg_replace('#([A-Z\d]+)([A-Z][a-z])#','\1_\2', $class);
$class = preg_replace('#([a-z\d])([A-Z])#', '\1_\2', $class);
return $class;
}
```
Also you have to update your top level namespace to `WpPluginTemplate` in both `wp-plugin-template.php` and `admin/plugin-meta.php` as you are using wp-plugin-template as your plugin folder name.
UPDATE:
When autoloader tries to find `Plugin_Meta` class, it will look into YOUR\_PLUGIN\_DIR/wp-plugin-template/admin/plugin-meta.php
In `wp-plugin-template.php`
```
<?php
/**
* Plugin Name: WP Plugin Template
*/
# If accessed directly, exit
if ( ! defined( 'ABSPATH' ) ) exit;
# Call the autoloader
require_once( 'autoloader.php' );
use WpPluginTemplate\admin\Plugin_Meta;
new Plugin_Meta;
```
In `wp-plugin-template/admin/plugin-meta.php`
```
<?php
namespace WpPluginTemplate\admin;
class Plugin_Meta {
public function __construct() {
add_action( 'plugins_loaded', array($this, 'test' ) );
}
public function test() {
echo 'It works!';
}
}
```

<p>Our WordPress website has a static html home page. A request for the domain returns the <code>index.html</code> page.</p>
<p>This has served our purposes well, but has caused a problem when trying to preview a post or page during editing. Since the preview URLs do not include <code>index.php</code> all preview requests display the static home page; e.g., </p>

I want to add a new image size option to the contents image editor. The code below is what I currently have but for some reason I am not seeing the option (as shown in the image below) in the editor. I am using WordPress Version 4.6.1. What could be the problem? Thanks in advance.
[](https://i.stack.imgur.com/HqWsm.png)
```
add_image_size( 'activity-image', 300, 300, array( 'center', 'center' ) );
// Add new image sizes to post or page editor
function new_image_sizes($sizes) {
return array_merge( $sizes, array(
'activity-image' => __( 'Activity Image' ),
) );
}
add_filter('image_size_names_chooser', 'new_image_sizes');
```
|
You need to register the image size first using [`add_image_size()`](http://www.wpbeginner.com/wp-tutorials/how-to-create-additional-image-sizes-in-wordpress/), for example:
```
add_action( 'after_setup_theme', 'cyb_add_image_sizes' );
function cyb_add_image_sizes() {
add_image_size( 'my-image-size-name', 120, 120, true );
}
```
Then, you can use the `image_size_names_choose` filter (you have misspelled it with `image_size_names_chooser`):
```
add_filter( 'image_size_names_choose', 'rudr_new_image_sizes' );
function rudr_new_image_sizes( $sizes ) {
$addsizes = array(
"my-image-size-name" => 'Misha size'
);
$newsizes = array_merge( $sizes, $addsizes );
return $newsizes;
}
```

I have a template with 4 css files: `rtl.css`, `style.css`, `main.css`, `bootstrap.css`.
`rtl.css` and `style.css` are located in my template root, for example:
`my_template_root/style.css`.
`main.css` and `bootstrap.css` are located, for example:
`my_template_root/assets/stylesheet/main.css`
`functions.php` code is:
```
add_action( 'wp_enqueue_scripts', 'my_theme_enqueue_styles' );
function my_theme_enqueue_styles() {
wp_enqueue_style( 'parent-style', get_directory_directory_uri() . 'style.css' );
}
```
This `functions.php` code apply correctly only for `rtl.css` and `style.css` but my changes in `main.css` and `bootstrap.css` don't work anyway.

You are calling your css files with wrong function like in following line of your code
```
wp_enqueue_style( 'parent-style', get_directory_directory_uri() . 'style.css' );
```
You are using `get_directory_directory_uri()` function to call files which is not event a function in wordpress.
Files must be called with one of the following two functions
1. **get\_stylesheeet\_directory\_uri()** : This function will search files in your active theme's folder. By active theme means, theme that is activated by user from `dashboard -> appearace -> theme`. In your case child theme is active, so it will search file in your child theme folder.
2. **get\_template\_directory\_uri()** : This function will search files in your parent theme's folder.
If your files are present in child theme's folder then add this code in `functions.php` to call your css files
```
add_action( 'wp_enqueue_scripts', 'my_theme_enqueue_styles' );
function my_theme_enqueue_styles() {
wp_enqueue_style( 'parent-style', get_stylesheet_uri() ); //It will call your style.css file
wp_enqueue_style( 'style1', get_stylesheeet_directory_uri() . '/rtl.css' );
wp_enqueue_style( 'style2', get_stylesheeet_directory_uri() . '/assets/stylesheet/main.css' );
wp_enqueue_style( 'style3', get_stylesheeet_directory_uri() . '/assets/stylesheet/bootstrap.css' );
}
```
In the above code `parent-style`, `style1`,`style2`,`style1` are the user assign name and that name must be unique.
And in one line only one file will be called, so if you wanna call 4 files then you have to specify path of all files in different lines.
**Note**: If your files are present in Parent theme's then you need to replace `get_stylesheeet_directory_uri` with `get_template_directory_uri` in above code.

You need to var\_dump wp\_query on 1st page and on 404 page
```
add_action( 'pre_get_posts', 'elo_jlb' );
function elo_jlb($query)
{

When using this code below with `wp_mail()` I always get in the header
[email protected]. And in Thunderbird in column Correspondents: Wordpress.
But I need: 'From: "Klantenservice"<' . $emailTo . '>'
In <https://developer.wordpress.org/reference/functions/wp_mail/> and other pages I can not find a solution for this.
```
$body = __('Name:', 'Avada')." $user_name \n\n";
$body .= __('Email:', 'Avada')." $user_email \n\n";
$body .= __('Telefoon:', 'Avada')." $telephone \n\n";

$emailTo = '[email protected]';
//$mail = wp_mail($user_email, $subject, $body, $headers);
$mail = wp_mail($emailTo, 'Contact verzoek', $body, '');
```
How can I get this correct?
**Here the solution add this in functions.php**:
```
add_filter( 'wp_mail_from_name', 'my_mail_from_name' );
function my_mail_from_name( $name )

It looks like you are setting the `$emailto` variable after the place you are using it.

Is there a way to add an "incorrect password" error message on password protected pages?
I've looked everywhere and the closest thing I can find is from here: [Add error message on password protected page](https://wordpress.stackexchange.com/questions/71284/add-error-message-on-password-protected-page)
The problem is that the error persists even when you navigate away from the page because it's based on cookies.
Something that seemed so simple is taking me hours to find a solution =\

Here's a combination of these two great answers ([21697](https://wordpress.stackexchange.com/questions/21697/password-protected-post-or-page-error-message-by-wrong-password) & [71284](https://wordpress.stackexchange.com/questions/71284/add-error-message-on-password-protected-page)) to similar questions.
`wpse241424_check_post_pass()` runs early on the `wp` hook on single password protected pages. If an invalid password is entered, the `INVALID_POST_PASS` constant is set for use later in the form, and the password entry error cookie is removed to prevent the error message from being visible each time.
`wpse241424_post_password_message()` is run right before rendering the password form. It checks for the `INVALID_POST_PASS` constant that it set earlier when an invalid password is encountered, and adds the error message to the form.
```
function wpse241424_check_post_pass() {
if ( ! is_single() || ! post_password_required() ) {
return;
}
if ( isset( $_COOKIE['wp-postpass_' . COOKIEHASH ] ) ) {
define( 'INVALID_POST_PASS', true );
// Tell the browser to remove the cookie so the message doesn't show up every time
setcookie( 'wp-postpass_' . COOKIEHASH, NULL, -1, COOKIEPATH );
}
}
add_action( 'wp', 'wpse241424_check_post_pass' );
/**
* Add a message to the password form if an invalid password has been entered.
*

* @param string $form
* @return string
*/
function wpse241424_post_password_message( $form ) {
if ( ! defined( 'INVALID_POST_PASS' ) ) {
return $form;
}
// Translate and escape.
$msg = esc_html__( 'Sorry, your password is wrong.', 'your_text_domain' );
// We have a cookie, but it doesn’t match the password.
$msg = "<p class='custom-password-message'>$msg</p>";
return $msg . $form;
}
add_filter( 'the_password_form', 'wpse241424_post_password_message' );

When a user is logged in, WordPress adds the class logged-in to the body tag, so you can target CSS differently for logged in users.
```
body > footer {
background: black;
}
body.logged-in > footer {
background: red;
}
```
for example.
This is only good for cosmetic changes though. Don't try to use it to hide information from non-logged in users as the content is still in the HTML.

<p>I have this function hardcoded into content-single-product.php (WooCommerce) and it works to show 3 random products from <strong>categories ID 64 and 72</strong>:</p>
<pre><code>$args = array(
'post_type' => 'product',
'post_status' => 'publish',
'posts_per_page' => '3',
'orderby' => 'rand',
'tax_query' => array(
'relation' => 'AND',
array(
'taxonomy' => 'product_cat',
'field' => 'term_id',
'terms' => array( 64, 72 ),
),
),
);
$loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post();
global $product;
</code></pre>
<p>Now, instead of hardcoding the category ID, I added a custom field to the product <code>MyCustomField</code> and wrote <strong>64,72</strong> in it. Then I tried to modify the above code to be populated dynamically:</p>
<pre><code>$MyCustomField = get_post_meta($post->ID, 'MyCustomField', true);
$args = array(
'post_type' => 'product',
'post_status' => 'publish',
'posts_per_page' => '3',
'orderby' => 'rand',
'tax_query' => array(
'relation' => 'AND',
array(

'terms' => array( $MyCustomField ),
),
),
);
$loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post();
global $product;
</code></pre>
<p>Unfortunately, this doesn't work correctly:</p>
<p><code>'terms' => array( $MyCustomField )</code></p>
<p>because it only displays products from the first category (ID 64), and not from both, as I want.</p>
<p>I'm a newbie programmer so what did I do wrong? Thanks!</p>

I have this function hardcoded into content-single-product.php (WooCommerce) and it works to show 3 random products from **categories ID 64 and 72**:
```
$args = array(
'post_type' => 'product',
'post_status' => 'publish',
'posts_per_page' => '3',
'orderby' => 'rand',
'tax_query' => array(
'relation' => 'AND',
array(
'taxonomy' => 'product_cat',
'field' => 'term_id',
'terms' => array( 64, 72 ),
),
),
);
$loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post();
global $product;
```
Now, instead of hardcoding the category ID, I added a custom field to the product `MyCustomField` and wrote **64,72** in it. Then I tried to modify the above code to be populated dynamically:
```
$MyCustomField = get_post_meta($post->ID, 'MyCustomField', true);
$args = array(
'post_type' => 'product',
'post_status' => 'publish',
'posts_per_page' => '3',
'orderby' => 'rand',
'tax_query' => array(
'relation' => 'AND',
array(
'taxonomy' => 'product_cat',
'field' => 'term_id',
'terms' => array( $MyCustomField ),
),
),
);
$loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post();
global $product;
```
Unfortunately, this doesn't work correctly:
`'terms' => array( $MyCustomField )`
because it only displays products from the first category (ID 64), and not from both, as I want.
I'm a newbie programmer so what did I do wrong? Thanks!

I suspect the problem is coming from `$MyCustomField` which you enter as such in:
```
'terms' => array( $MyCustomField ),
```
The query consider it as only one value: `'64,72'`, a string.
So try:
```
$MyCustomFieldValues = array_map( 'intval', explode( ',', $MyCustomField ) );
```
This will also ensure your values are integers.
Then:
```
'terms' => $MyCustomFieldValues,
```

My custom made plugin has "a new version available", also the "view details" link links to a completely unrelated plugin.
The plugin files begins with:
```
<?php
/*
Plugin Name: Simple Contact Form
Plugin URI: http://www.wilcoverhoeven.com
Description: Simple contact form
Version: 1
Author: Wilco Verhoeven
Author URI: http://www.wilcoverhoeven.com
*/
```
How can I prevent this?
|
I think you've got a naming conflict there -- assuming that your plugin is linking to [this](https://en-gb.wordpress.org/plugins/simple-contact-form/) Simple Contact Form -- try changing the name to something like "Wilco's Simple Contact Form".
You'll need to update the plugin folder name and the main plugin file name as well.
**Update**
As [Aniket](https://wordpress.stackexchange.com/users/104130/aniket) points out, you might need to force an update check on your site to get rid of the notice. You can do this by going to `http://yourwebsite.com/wp-admin/update-core.php?force-check=1`

<p>I'm trying to add a PureCSS class to the <code><form></code> tag in the default comments template, but the class isn't being added. Here's what I've done so far:</p>
<pre><code>function pwp_comments_form_pure($output) {
$output = preg_replace('/class="comment-form"/', 'class="comment-form pure-form"', $output);
return $output;
}
add_filter('comments_template', 'pwp_comments_form_pure');
</code></pre>
<p>I know the <code>preg_replace</code> approach works, because I did the same for the default search form and it worked without any problems:</p>
<pre><code>function pwp_search_form_pure($output) {
$output = preg_replace('/class="searchform"/', 'class="searchform pure-form"', $output);
return $output;
}
add_filter('get_search_form', 'pwp_search_form_pure');
</code></pre>
<p>I've triple-checked the class names and hyphenation, and they all match up.</p>
<p>I've also tried adding a priority parameter of 1 and 100 to the <code>comments_template</code> filter, but it didn't make a difference.</p>
<p>Is there an override somewhere in the WordPress defaults that I'm not aware of?</p>

Any `comments_template` filter should return [an absolute filepath to the comments template](https://codex.wordpress.org/Plugin_API/Filter_Reference/comments_template) - use `comment_form_defaults` and set the `class_form` argument:
```
add_filter( 'comment_form_defaults', function ( $args ) {
$args['class_form'] = 'my form classes';
return $args;
});
```

<p>I am working on a plugin that posts an XML request to a vendor's shipping API to get shipping quotes. The XML is stored in a string called $xml. I can post the XML request successfully with curl using these parameters:</p>
<pre><code>$curl = curl_init( $this->settings['api_url'] );
curl_setopt( $curl, CURLOPT_HEADER, 0 );
curl_setopt( $curl, CURLOPT_POST, 1 );
curl_setopt( $curl, CURLOPT_TIMEOUT, 45 );
curl_setopt( $curl, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt( $curl, CURLOPT_SSL_VERIFYPEER, 0 );
curl_setopt( $curl, CURLOPT_SSL_VERIFYHOST, 0 );
curl_setopt( $curl, CURLOPT_POSTFIELDS, $xml );
$result = curl_exec( $curl );
curl_close( $curl );
</code></pre>
<p>My question is, how can I do the same thing with WordPress HTTP API? I want to maximize compatibility for those that may not have curl on their servers.</p>
<p>Here is the HTTP API attempt I have made:</p>
<pre><code>$result = wp_remote_post(
$this->settings['api_url'],
array(
'method' => 'POST',
'timeout' => 45,
'redirection' => 5,
'httpversion' => '1.1',
'headers' => array(
'Content-Type' => 'text/xml'
),
'body' => array(
'postdata' => $xml
),
'sslverify' => 'false'
)
);
</code></pre>
<p>I have tried changing the body to just:</p>
<pre><code>'body' => array( $xml ),
</code></pre>
<p>I have tried converting the $xml to a php associative array with simple xml and json.</p>
<p>With all of my attempts, I keep getting back an error in my vendor's response: "Content is not allowed in prolog." It would seem that the XML is either not being posted properly or HTTP API is maybe including a Byte Order Mark (BOM).</p>
<p>Hoping someone can help. Thanks.</p>

I tried some more trial and error and managed to get it to work by simply putting $xml as the body without specifying it as an array. The function reference says, "Post data should be sent in the body as an array," so I'm not sure why it worked.
Here is the working code in case it helps someone else:
```
// Sends the xml request to the API
$result = wp_remote_post(
$this->settings['api_url'],
array(
'method' => 'POST',
'timeout' => 45,
'redirection' => 5,
'httpversion' => '1.1',

'Content-Type' => 'text/xml'

'body' => $xml,
'sslverify' => 'false'

<p>Learning PHP and a little stuck on a fairly straight forward issue.
I am trying to edit my WooCommerce invoice</p>
<p>This code <code><?php echo $sign.number_format($order->get_subtotal(),2); ?></code> Returns $50.98</p>
<p>This code <code>$first_number = $order->get_subtotal();</code> Returns a variable of 51, it rounds up as the <code>,2</code> is missing.
How do I add <code>(),2;</code> to the above code so it returns that variable just as a number with decimals so i can make calculations with it.</p>

Try
```
$first_number = number_format( $order->get_subtotal(), 2 );
```
number\_format() is the php function that is setting the decimals in your first bit of code above.
See <http://php.net/manual/en/function.number-format.php>

<p>I want to query posts where meta value is empty. for example, I want to get these three posts, with no meta values:
<a href="https://i.stack.imgur.com/9U69t.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/9U69t.jpg" alt="enter image description here"></a></p>
<p>Already tried:</p>
<pre><code>$args = array(
'post_type' => 'attachment',
'posts_per_page' => 10,
'paged' => $paged,
'meta_query' => array(
array(
'key' => '_wp_attachment_image_alt',
'value' => '',
'compare' => 'LIKE'
)
)
);
$attachments = new WP_Query($args);
</code></pre>
<p>and:</p>
<pre><code>$args = array(
'post_type' => 'attachment',
'posts_per_page' => 10,
'paged' => $paged,
'meta_query' => array(
array(

'value' => null,
'compare' => 'LIKE'
)
)
);
</code></pre>
<p>But it doesn't work..</p>
<p>Any idea how to solve this?</p>
<p>Thank you</p>

But it doesn't work..
Any idea how to solve this?
Thank you

I think you forgot about the *inherit* post status. The default one in `WP_Query` is *publish*.
You should also use `=` instead of `LIKE`, to avoid using `LIKE '%%'` in the SQL query.
So try to add this:
```
'post_status' => 'inherit'
```
and
```
'compare' => '='
```
into your query arguments, to match the empty `_wp_attachment_image_alt` string values.

<p>I am attaching an image to a post with the media import command.</p>
<p>I know I can get the image id using the --porcelain option, but how can I get the image url from this id?</p>
<p>Or is there a way to display the featured image's url of a post (apparently the list command does allow this)?</p>

Or is there a way to display the featured image's url of a post (apparently the list command does allow this)?

Assuming the attachment ID were in a variable of `$attachment_id` you could use the following command:
```
# get attachment URL
wp db query "SELECT guid FROM $(wp db tables *_posts) WHERE ID=\"$attachment_id\"" | head -n 2 | tail -1
```
I use the `$(wp db tables *_posts)` bit just in case the `wp_` table prefix is non-default.

<p>I tried to include shortcodes with a parameter in raw html output, like shown below:</p>
<pre><code><a href="https://example.com/folder/edit.php?action=someaction&id=[foocode parameter='value']&edittoken=[foocode parameter='othervalue']">linktext</a>

<p>This crashes the PHP function <code>do_shortcode()</code>.</p>
<p>Is stuff like this really not possible with shortcodes?</p>
<p>The method description itself contains a warning:</p>

<pre><code>function echocode( $atts ){

<p>and added as</p>
<pre><code>add_shortcode("foocode", "echocode");

<p>I'm displaying a table of laptops, where the table header is a row of custom fields, and each following row is a laptop name and it's custom field values in each of the corresponding column cells.</p>
<p>I want to be able to sort the table by clicking on the table <code>TH</code> cell containing the custom field name.</p>
<p>I've been pointed to <a href="https://make.wordpress.org/core/2015/03/30/query-improvements-in-wp-4-2-orderby-and-meta_query/" rel="nofollow">meta query clauses</a> by ACF support, but I'm out of my depth with those.</p>
<p>I'd really appreciate some help in generating URLs to wrap around the the custom field name in each <code>TH</code> element.</p>

To follow up on @rock3t's comment, do you really have to query the backend whenever a user clicks on a column header?
Have you looking into using the jQuery [tablesorter](https://plugins.jquery.com/tablesorter/)? It allows an end-user to sort an HTML table by doing DOM manipulations.
I've never used it in a WP project, but I have used it extensively in other projects I've built and it works great. It's **very** configurable, so I'm sure it will satisfy your needs.
tablesorter is **not** one of the jQuery plugins included with WP Core. So you'll have to download it (from the above link), include it in your plugin/theme somewhere and enqueue it. Then, enqueue a simple JS file that would like something like:
```
(function ($) {
$(document).ready (function () {
$('#id_of_your_table').tablesorter ({widgets: ['zebra']}) ;
}) ;
})(jQuery) ;
```
You can read more about how to use tablesort in their [docs](https://mottie.github.io/tablesorter/docs/index.html), including various other parms to the `tablesorter()` method.

<p>Is any way to don`t display shrort description in a single entry page?</p>
<p>It is necessary to be able to write any text, then paste the tag "more". This content should be displayed only on the list of records page. But it should not be displayed on the single entry page.</p>

To follow up on @rock3t's comment, do you really have to query the backend whenever a user clicks on a column header?
Have you looking into using the jQuery [tablesorter](https://plugins.jquery.com/tablesorter/)? It allows an end-user to sort an HTML table by doing DOM manipulations.
I've never used it in a WP project, but I have used it extensively in other projects I've built and it works great. It's **very** configurable, so I'm sure it will satisfy your needs.
tablesorter is **not** one of the jQuery plugins included with WP Core. So you'll have to download it (from the above link), include it in your plugin/theme somewhere and enqueue it. Then, enqueue a simple JS file that would like something like:
```
(function ($) {
$(document).ready (function () {
$('#id_of_your_table').tablesorter ({widgets: ['zebra']}) ;
}) ;
})(jQuery) ;
```
You can read more about how to use tablesort in their [docs](https://mottie.github.io/tablesorter/docs/index.html), including various other parms to the `tablesorter()` method.

For example, if I have a custom post type that are '**Case Studies**',
Firstly I need to be able to query the post types for a **single** specific case study, but then lets say there are a few **variations** of that single case study;
'Wales', 'England', 'Scotland'... . The correct one needs to be picked out depending on the category taxonomy for that post (of the same name).
When the specific case study and its variation has been found, let's say:
Case Study: Highest Mountain
Category (taxonomy) of custom post: Scotland
I need to then put this information into a html template, for example the output would be (data pulled from the custom post):
```
<h3>Highest Mountain</h3>
<p>Here would be the content specific to Scotland...</p>
```
So when the shortcode is entered into the\_content textarea by the user, all they have to input is e.g.
```
[casestudy study_type="mountain"]
```
When registering a new post for 'Case Studies', the category taxonomy (variation) would be selected. So if the Category chosen for the post was 'Scotland', and the user had this country selected in their user profile - it would pull the variation of that case study (e.g. mountain) specific to Scotland.
All help much appreciated, I haven't written a custom shortcode before - so the more explanation the better - thanks!

From your supplied info, it's not all very clear to me. But as far as I've understood your problem, here's my approach.
Assuming we have the following shortcode that the user has put inside a **normal** post's content and that this shortcode will pull information from your custom post type `case_studies`:
```
[casestudy study_type="mountain"]
```
So firstly, your shortcode handler:
```
add_shortcode( 'casestudy', 'my_shortcode' );
function my_shortcode( $atts ) {
$a = shortcode_atts( array(
'study_type' => 'mountain',
), $atts );
$content = my_template( $a );
return $content;
}
```
Pay close attention to the [`shortocode_atts()`](https://codex.wordpress.org/Function_Reference/shortcode_atts) function. It's meant to filter the **accepted** parameters that your template function's query below will be able to handle.
Then, your template:
```
function my_template( $a ) {
/**
* I believe we should be in the loop already when this function is being called.
* So to get the category slug of the current post in which the user has put the shortcode, you can try this.
*/
$category_terms = get_the_category();
$args = array(
'post_type' => 'case_studies',
'name' => $a['study_type'],
'category_name' => $category_terms[0]->slug,
'posts_per_page' => 1,
);
$query = new WP_Query( $args );
ob_start();
if ( $query->have_posts() ) {
while ( $query->have_posts() ) {
the_post();
echo '<h3>' . get_the_title() . '</h3>';
echo '<p>' . get_the_content() . '</p>';
}
reset_postdata();
}
return ob_get_clean();
}
```

```
public function dmd_fav_modal_box() {

</div>
</div>
</div>';
return $content;
}
```
In my constructor I tried some filter and actions.
E.g.
```
add_action( 'wp_head', array($this, 'dmd_fav_modal_box') );
add_filter( 'the_content', array($this, 'dmd_fav_modal_box') );
```
But nothing works. Can somebody help me?

You only need the\_content filter to add the modal, but bootstrap.js is needed to make it work.
```
add_action('wp_enqueue_scripts', array($this, 'enqueue_bootstrap');
public function enqueue_bootstrap(){
wp_register_script( 'bootstrap', plugins_url( 'your-plugin/assets/js/bootstrap.min.js' ) );
wp_enqueue_script( 'bootstrap' );
}
```
EDIT:
You need to add $content argument to your function.
As the codex says
>
> Note that the filter function must return the content after it is finished processing, or site visitors will see a blank page and other plugins also filtering the content may generate errors.
>
>
>
in your case:
```
public function dmd_fav_modal_box($content) {
$modal = '<div class="modal fade" id="dmd_favorite_modal" tabindex="-1" role="dialog" aria-labelledby="dmd_favorite_modalLabel">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button>
</div>
<div class="modal-body">
<p>Test</p>
</div>
<!--div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div-->
</div>
</div>
</div>';
return $modal.$content;

<p>The idea here is to be able to use the Link button to search through posts as usual, but, once selected, use the shortlink (with something like <code>wp_get_shortlink();</code>) instead of the permalink:</p>
<p><code><a href="http://example.com/?p=1234">The Link</a></code></p>
<p>Not sure if it would be easier to add this function to the existing button or add a new button with this dedicated behavior.</p>

The idea here is to be able to use the Link button to search through posts as usual, but, once selected, use the shortlink (with something like `wp_get_shortlink();`) instead of the permalink:
`<a href="http://example.com/?p=1234">The Link</a>`
Not sure if it would be easier to add this function to the existing button or add a new button with this dedicated behavior.
|
If you mean the *link dialog*, then we can modify the *permalinks* with the [`wp_link_query`](https://developer.wordpress.org/reference/hooks/wp_link_query/) filter:
```
add_filter( 'wp_link_query', function( $results )
{
foreach( $results as &$result )
$result['permalink'] = wp_get_shortlink( $result['ID'] );
return $results;
} );
```
where we use [`wp_get_shortlink()`](https://codex.wordpress.org/Function_Reference/wp_get_shortlink) to get the *short links*.

<p>When you request posts using WP API's search mechanism, it returns tags as one of the post's properties, but it is an array of tag IDs, not tag names. Is there a way to make the API include the name of the tags without making subsequent requests to the API by tag ID for each one?</p>
<pre><code>tags: [
188,
30,
151,
189
]
</code></pre>
<p>I couldn't find any parameter in the API docs that does this, so I was thinking of creating a custom plugin to maybe filter and substitute the tag ID's for names before the response is sent back to the API caller. In that case, what action should I listen for?</p>

I figured something out based on what I found at this [post](https://www.haselt.com/blog/wp-rest-api-modifying-the-json-response).
Basically I need a plugin that listens for when the REST response is about to go out. The plugin code would be similar to the following:
```
function ag_filter_post_json($response, $post, $context) {
$tags = wp_get_post_tags($post->ID);
$response->data['tag_names'] = [];
foreach ($tags as $tag) {
$response->data['tag_names'][] = $tag->name;
}
return $response;
}
add_filter( 'rest_prepare_post', 'ag_filter_post_json', 10, 3 );
```
It adds the tag names as a new property called `tag_names`. The rest of the heavy lifting is done by the [`wp_get_post_tags`](https://codex.wordpress.org/Function_Reference/wp_get_post_tags) function.

Use this function instead. Then put `the_excerpt();` in your template.
```
/**
* Find the last period in the excerpt and remove everything after it.
* If no period is found, just return the entire excerpt.
*
* @param string $excerpt The post excerpt.
*/
function end_with_sentence( $excerpt ) {

$excerpt = substr( $excerpt, 0, $pos + 1 );
}
return $excerpt;
}
add_filter( 'the_excerpt', 'end_with_sentence' );

<p>I've implemented some AJAX functionality for my plugin and it works fine as long as I'm not logged in as admin - then <code>wp_verify_nonce</code> fails. It works for unauthorized users and authorized regular users too.</p>
<p>Here's my PHP class (I removed everything that is not relevant to the issue):</p>
<pre><code>class My_Ajax {

}
function geoip_citylist() {
if ( ! wp_verify_nonce($_POST['geoipNonce'], 'my_geoip_nonce') ) {
exit('Wrong nonce: ' . $_POST['geoipNonce']);
}
}
function geoip_localize_js() {
wp_localize_script(
'my_custom_js', 'myGeoipAjaxObject',
array(
'myGeoipNonce' => wp_create_nonce('my_geoip_nonce')
)
);
}
}
</code></pre>
<p>And here's my Javascript:</p>
<pre><code>$.ajax({
url: myMainAjaxObject.ajaxUrl,
type: 'POST',
dataType: 'json',
data: {
geoipNonce: myGeoipAjaxObject.myGeoipNonce,
action: "geoip_citylist"
},
success: function(data) {
replacePhones(data.user_city, data.current_phone, data.city_list);
},
error: function(error) {
console.log(error);
}
});
</code></pre>
<p>The nonce in PHP error response seems to be correct, but it still doesn't validate for some reason.</p>
<p>I've spent days trying to figure out what's wrong and trying to google this in every possible way, but so far I couldn't find a solution that would work. There are unanswered questions with similar issues on stackoverflow, like <a href="https://stackoverflow.com/questions/7375058/wordpress-nonce-check-always-false#comment67104942_7375058">this one</a> which was created in 2011...

<p><strong>UPDATE:</strong>
I've tried to use just the code that I provided here and it still resulted with the same error (I also double checked the cache and it was refreshed).</p>
<p><strong>UPDATE 2:</strong>
<code>myMainAjaxObject</code> and its <code>ajaxUrl</code> are inserted in another script. Since AJAX URL is same for every AJAX request, I just use the global one instead of redefining it every time. So this is not what's causing the error. Also if it wouldn't be defined it would never work. Once again, it doesn't work only for the admin, for other users and unauthorized users it works fine. And I do get "Wrong nonce: 73dd02f662" in the server response when I'm logged as admin. So I'm 100% sure that URL is correct.</p>

I think the problem was that I manually deleted my cookies a few times while testing. Among them was a cookie called "wordpress\_logged\_in\_{token}" where {token} is an unique identifier. My best guess is that lack of this cookie caused issues with nonce creation or/and verification. It was hard to notice because I was still able to browse the admin panel (it looks like there WP is using a different cookie called "wordpress\_{token}") and on the front end this website doesn't show user status anywhere (accounts are not used there, however login functionality is there, just hidden from the view).
The solution was very simple - I just re-logged as admin and my AJAX started working for the admin as well. So if someone runs into a similar issue, make sure that when you clear cookies, you either delete only ones that you need to remove/regenerate or, if you delete all of them like I did, make sure to re-log as admin.

<p>many users would to allow the registration in a wp site without an username, just only with an email.</p>
<p>This is a core problem, so the solution (a trick) is to replace username with email.</p>
<p>If wp requires an username and an email for the registration, we can get email value and put it in username value. In the registration form users will see two fields: </p>
<ol>
<li>your email</li>
<li>repeat your email</li>
</ol>
<p>This is a trick, because for wp the real fields will be:
1. username (as your email)
2. your email (as repeat your email)</p>
<p>But there is another problem: is the <em>@</em> (at) an allowed character for username?</p>
<p>How can we do this?</p>
<p>Should we insert a code in <em>functions.php</em> file?.. something like this:</p>
<pre><code>add_action( 'wp_core_validate_user_signup', 'custom_validate_user_signup' );
function custom_validate_user_signup($result)
{
unset($result['errors']->errors['user_name']);

many users would to allow the registration in a wp site without an username, just only with an email.
This is a core problem, so the solution (a trick) is to replace username with email.
If wp requires an username and an email for the registration, we can get email value and put it in username value. In the registration form users will see two fields:
1. your email
2. repeat your email
This is a trick, because for wp the real fields will be:
1. username (as your email)
2. your email (as repeat your email)
But there is another problem: is the *@* (at) an allowed character for username?
How can we do this?
Should we insert a code in *functions.php* file?.. something like this:
```
add_action( 'wp_core_validate_user_signup', 'custom_validate_user_signup' );
function custom_validate_user_signup($result)
{
unset($result['errors']->errors['user_name']);
if(!empty($result['user_email']) && empty($result['errors']->errors['user_email']))
{
$result['user_name'] = md5($result['user_email']);
$_POST['signup_username'] = $result['user_name'];
}
return $result;
}
```
Thank you in advance!

You can use `@` and `.` in usernames, so there is no problem. Now you could create your own register form and use [`register_new_user()`](https://codex.wordpress.org/Function_Reference/register_new_user). You could even manipulate [`wp_registration_url()`](https://codex.wordpress.org/Function_Reference/wp_registration_url) with the filter [`register_url`](https://codex.wordpress.org/Plugin_API/Filter_Reference/register_url), so the register link would point to your new register page.
If you want to use it with the standard interface provided by *wp-login.php*, you would need some workarounds. Lets say, you only want to display the email input field for registration, you could simply (well, its a bit hacky though) hide the username field with something like this:
```
add_action( 'register_form', function() {
?><style>#registerform > p:first-child{display:none;}</style><?php
} );
```
Sidenote: There is also a possibility to enqueue stylesheets into the *wp-login.php* using the `login_enqueue_scripts` action.
But if you do so you will send an empty username, so you have to hook into two filters: [`sanitize_user`](https://codex.wordpress.org/Plugin_API/Filter_Reference/sanitize_user) and `validate_username`.
```
add_filter( 'sanitize_user', function( $sanitized_user, $raw_user, $strict ) {
if ( $raw_user != '' ) {
return $sanitized_user;
}
if ( ! empty ( $_REQUEST['action'] ) && $_REQUEST['action'] === 'register' && is_email( $_POST['user_email'] ) ) {
return $_POST['user_email'];
}
return $sanitized_user;
}, 10, 3 );
add_filter( 'validate_username', function( $valid, $username ) {
if ( $valid ) {
return $valid;
}
if ( ! empty ( $_REQUEST['action'] ) && $_REQUEST['action'] === 'register' && is_email( $_POST['user_email'] ) ) {
return true;
}
return is_email( $username );
}, 10, 2 );
```
In `sanitize_user` we replace the empty string with the email address. Later the username will be validated with `validate_username`, but again, the empty username will be used, so we need to catch this too.
But I think to create an own form would be preferred and less hacky.

<p>I have lots of Word documents that form training materials for work. I would like to develop a website to act as a repository for these documents. However, rather than just store them on a web server and provide links to the files, I would like (if possible) for the visitor to be able to view the documents via the website and print it from there (or choose to download the actual Word document if they so wish).</p>
<p>I know that you can 'save' a Word document as a .html page and then I could potentially upload them all but I was really hoping for something a bit less clunky. And also to embed the Word documents into my web pages with a custom header/footer so they looked like a normal page on the website and fitted in with everything else.</p>
<p>Is this possible?</p>
<p>Thanks.</p>

The real problem here is the download offer. Let's separate the two tasks first, to see that better.
Upload
------
### 1. … from Word directly
Word can communicate with WordPress directly per `xmlrpc.php`. When you ope a new file, select **Blog post** as template, then enter your user credentials once. Word will remember those. It might be useful to use a separate account for that, just in case MS is phoning home that too.
Now you can publish your Word text directly to WordPress. You can also edit them later, and even import existing blog posts for further editing. Keep in mind that Word will embed its own styles directly into the HTML code. This is rather ugly.
There is a [post on WPMU Dev about the details](https://premium.wpmudev.org/blog/how-to-use-microsoft-word-to-publish-directly-to-your-wordpress-site/).
2. … as PDF
-----------
There are many drivers for Windows which allow you to print a document as PDF. Either find one with a developer API and an event handling, so you can attach an upload handler to the print action, or write a custom shell script that is watching one directory on your hard drive and will upload the file whenever one is changed or replaced.
The tricky part here is that you cannot publish a PDF as blog post, and you have to add the file to the media library. The latter can be done per XML RPC too.
Download
--------
If your text is stored as HTML, like in the first option, you would have to convert the HTML back to Word again. There are many tools for that. You could try [PHPWord](https://github.com/PHPOffice/PHPWord).
The actual WordPress handler could listen on the actions in `wp-admin/admin-post.php` as described in Export data as [CSV in back end with proper HTTP headers](https://wordpress.stackexchange.com/a/102452/73):
```
if ( is_admin() )
{
$action = 'print_doc';
add_action( "admin_post_nopriv_{$action}", 'print_word' );
add_action( "admin_post_{$action}", 'print_word' );
}
function print_word()
{
$post_id = filter_input( INPUT_GET, 'id', FILTER_VALIDATE_INT );
if ( ! $post_id )
return;
$post = get_post( $post_id );
status_header( 200 );
header('Content-Type: application/vnd.openxmlformats-officedocument.wordprocessingml.document');
header('Content-Disposition: attachment; filename=' . $post->post_name . '.docx');
header('Pragma: no-cache');
// Convert $post->post_content to Word
// Output the Word document
exit;
}
```
To create the link on the front end, you can filter `the_content`:
```
if ( ! is_admin() )
{
add_filter( 'the_content', function( $content ) {
if ( ! is_singular() )
return $content;
$post_id = get_the_ID();
$url = admin_url( 'admin-post.php' );
$link = sprintf(
'<p class="download-link"><a href="%s">Download</a></p>',
admin_url( 'admin-post.php' ) . '?action=print_doc&id=' . $post_id
);
return $content . $link;
});
}
```
If you have uploaded the file as PDF, use `get_attached_media()` here, filter its return value for PDF. and create the link the same way as above.

<p>I am trying to access data from another website to display on a WordPress Website I am developing. So far I have the following:</p>

<p>Before deciding to ask this question, I googled and searched this forum, but found no answer to my question, even though it may seem like a duplicate.</p>
<p>Anyway, I made custom post type that uses its featured image. Now, I would like to set if no featured image exists, show post content and by that I mean show whatever it is in my post ( in my case it is embedded youtube video).</p>
<p>So far I added to functions.php the following:</p>
<pre><code>function zm_get_backend_preview_thumb($post_ID) {
$post_thumbnail_id = get_post_thumbnail_id($post_ID);
if ($post_thumbnail_id) {
$post_thumbnail_img = wp_get_attachment_image_src($post_thumbnail_id, 'thumbnail');
return $post_thumbnail_img[0];
}
}
function zm_preview_thumb_column_head($defaults) {
$defaults['featured_image'] = 'Image';
return $defaults;
}
add_filter('manage_posts_columns', 'zm_preview_thumb_column_head');
function zm_preview_thumb_column($column_name, $post_ID) {
if ($column_name == 'featured_image') {
$post_featured_image = zm_get_backend_preview_thumb($post_ID);
if ($post_featured_image) {
echo '<img src="' . $post_featured_image . '" />';
}
}
}
add_action('manage_posts_custom_column', 'zm_preview_thumb_column', 10, 2);
}
</code></pre>
<p>And in my page where I would like to show the video instead featured image, I have the following code:</p>
<pre><code><?php
// WP_Query arguments
$args = array (
'post_type' => array( 'zm_gallery' ),
);
// The Query
$query_gallery = new WP_Query( $args );
// The Loop
if ( $query_gallery->have_posts() ) {
while ( $query_gallery->have_posts() ) {
$query_gallery->the_post();
echo '<ul>';
echo '<li>';
$name = get_post_meta($post->ID, 'ExternalUrl', true);
if( $name ) { ?>
<a href="<?php echo $name; ?>"target="_blank"><?php the_post_thumbnail(); ?></a>
<?php
} else {
the_post_thumbnail();
}
echo '</li>';
echo '</ul>';
}
} else {
if ( "" === $post->post_content ) {
the_post_thumbnail();
} else {
the_content();
}
}
// Restore original Post Data
wp_reset_postdata();
?>
</code></pre>
<p>Your help would be highly appreciated. Thank you all in advance.</p>

Before deciding to ask this question, I googled and searched this forum, but found no answer to my question, even though it may seem like a duplicate.
Anyway, I made custom post type that uses its featured image. Now, I would like to set if no featured image exists, show post content and by that I mean show whatever it is in my post ( in my case it is embedded youtube video).
So far I added to functions.php the following:
```
function zm_get_backend_preview_thumb($post_ID) {
$post_thumbnail_id = get_post_thumbnail_id($post_ID);
if ($post_thumbnail_id) {
$post_thumbnail_img = wp_get_attachment_image_src($post_thumbnail_id, 'thumbnail');
return $post_thumbnail_img[0];
}
}
function zm_preview_thumb_column_head($defaults) {
$defaults['featured_image'] = 'Image';
return $defaults;
}
add_filter('manage_posts_columns', 'zm_preview_thumb_column_head');
function zm_preview_thumb_column($column_name, $post_ID) {
if ($column_name == 'featured_image') {
$post_featured_image = zm_get_backend_preview_thumb($post_ID);
if ($post_featured_image) {
echo '<img src="' . $post_featured_image . '" />';
}
}
}
add_action('manage_posts_custom_column', 'zm_preview_thumb_column', 10, 2);
}
```
And in my page where I would like to show the video instead featured image, I have the following code:
```
<?php
// WP_Query arguments
$args = array (
'post_type' => array( 'zm_gallery' ),
);
// The Query
$query_gallery = new WP_Query( $args );
// The Loop
if ( $query_gallery->have_posts() ) {
while ( $query_gallery->have_posts() ) {
$query_gallery->the_post();
echo '<ul>';
echo '<li>';
$name = get_post_meta($post->ID, 'ExternalUrl', true);
if( $name ) { ?>
<a href="<?php echo $name; ?>"target="_blank"><?php the_post_thumbnail(); ?></a>
<?php
} else {
the_post_thumbnail();
}
echo '</li>';
echo '</ul>';
}
} else {
if ( "" === $post->post_content ) {
the_post_thumbnail();
} else {
the_content();
}
}
// Restore original Post Data
wp_reset_postdata();
?>
```
Your help would be highly appreciated. Thank you all in advance.
|
the\_post\_thumbnail will echo out the thumbnail so maybe try
```
if ( has_post_thumbnail() ) {
the_post_thumbnail();
} else {
the_content();
}
```
Hope this helps

<p>I have a WP Plugin where i use Font-Awesome Icons. I added the Font-Awesome folder to my Plugin Files and told WordPress to use them:</p>

It was not Font-Awesome that changed the default WordPress Style. I also use Bootstrap. One file called scaffolding.less overrides the WordPress defaults with:
```
// Body reset
html {
font-size: 10px;
-webkit-tap-highlight-color: rgba(0,0,0,0);
}
body {
font-family: @font-family-base;
font-size: @font-size-base;
line-height: @line-height-base;
color: @text-color;
background-color: @body-bg;
}
```
I just added this to my custom CSS File (original WordPress CSS) with !important:
```
/* Override Bootstrap Reset with WP default */
body {
font-family: -apple-system,BlinkMacSystemFont,"Segoe UI",Roboto,Oxygen-Sans,Ubuntu,Cantarell,"Helvetica Neue",sans-serif !important;
}
```
Now WordPress looks like it should again.

<p>after <a href="https://stackoverflow.com/questions/39920420/wordpress-strange-permission-issue">this problem</a> I think that there is a problem if I have two wordpress installation on one pc.

<p>So the problem is that nothing I've install into the second wordpress is working correct or visible. I've upload Media, Install themes and plugins but I can't see their resources such as images and etc.
I think that this is Alias problem - I have the same alias into every site.conf under /etc/apache2/site-available

I've [created a plugin](https://wordpress.org/plugins/remove-http/) that turns all links into protocol relative URLs, like so:
```
http://example.com -> //example.com
```
I'm also adding a function to force HTTPS only if SSL is enabled and set up properly on the website. The following function below will force HTTPS regardless if it has been set up correctly:
```
add_action ( 'template_redirect', 'force_https', 1 );
function force_https() {
if ( ! is_ssl() ) {
wp_redirect('https://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'], 301 );
exit();
}
}
```
However, if SSL hasn't been configured for the website, it will cause a connection error and the user won't be able to access their website. This is where I want to put a check before it executes the [`wp_redirect()`](https://developer.wordpress.org/reference/functions/wp_redirect/).
My idea is to check if the [`get_home_url()`](https://developer.wordpress.org/reference/functions/get_home_url/) option has `https://` in the URL:
```
if ( preg_match( '/https:\/\//', site_url() ) && ! is_ssl() ) {
```
Is there a better way to check? Or is it not even necessary to force HTTPS if my first function from my plugin has made all of the links protocol-relative?
|
Based on the comments, there is no foolproof way to check if someone's website has SSL set up correctly. Possible options include a setting in the plugin to have the user confirm that they have SSL set up.
However, one automated way is to check if the site URL has `https://` in it. This is assumed that SSL has been set up properly by the user since the website wouldn't load correctly if they try to set the domain with HTTPS:
```
add_action( 'template_redirect', 'wpse_241934_redirect_https', 1, 1 );
function redirect_https() {
# If 'https://' is in the website's site URL and SSL is not being used, force HTTPS
if ( preg_match( '/https:\/\//', site_url() ) && ! is_ssl() ) {
wp_redirect( 'https://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'], 301 );
exit;
}
}
```
For me, this function wouldn't be necessary since my plugin makes all URLs protocol-relative. This could still be helpful for anyone else who wants to execute a function if a website is running SSL only.

<p>I've been trying to figure this out for about a week and I've got a few different methods that 'work' but I don't feel like are the best/right solutions for the project.</p>
<p>I'm trying to do the following:
I've got grid items that are populated via the WP Posts loop.
The grid items themselves are then wrapped in an tag wherein the post ID is grabbed as a data attribute like so:</p>
<pre><code> <section class="GRIDSECTION">
<?php
query_posts('post_type=CUSTOMTYPE');
while (have_posts()) : the_post();
$postID = get_the_ID();
?>
<a class="GRIDITEM" href="#" data-post_id='<?php echo $postID; ?>' data-post_type='POST-TYPE'>
<h2><?php the_title(); ?></h2>
<span><?php the_field('CUSTOM-CONTENT');?></span>
</a>
<?php
endwhile;
?>
</section>
</code></pre>
<p>And then my AJAX script based on some of the reading I've done:</p>
<pre><code>console.log('01 - AJAX Loaded');
$(".GRIDITEM").click(function () {
console.log('02 - AJAX Starting');
//var id_post = $(this).attr('post_id');
$.ajax({
type: 'POST',
url: '<?php echo admin_url('admin-ajax.php'); ?>',
data: {
'post_id': ?????,
'action': 'f711_get_post_content' //this is the name of the AJAX method called in WordPress
}, success: function (result) {
console.log('03a - SUCCESS');
alert(result);
},
error: function () {
alert("error");
console.log('03b - FAILURE');
}
});
});
</code></pre>
<p>I'm not sure how to connect pass the ID into the data type with this method.
I figured once I manage to get the post_id passed in, I can do the same thing for the POST-TYPE. </p>
<p>What I intend to do is pass the Post ID and the Custom Post Type into Ajax to send and receive the Post that the GRIDITEM represents.</p>
<p>And then of course, return back to where I started.</p>
<p>Here's the overall feel I want to achieve.</p>
<p><a href="http://tympanus.net/Development/AnimatedGridLayout/" rel="nofollow">http://tympanus.net/Development/AnimatedGridLayout/</a></p>
<p>But since we use custom post types and custom fields in each post, I'm not sure how to call that in. Plus I've only just started using AJAX.</p>
<p>Thanks!</p>

I've been trying to figure this out for about a week and I've got a few different methods that 'work' but I don't feel like are the best/right solutions for the project.
I'm trying to do the following:
I've got grid items that are populated via the WP Posts loop.
The grid items themselves are then wrapped in an tag wherein the post ID is grabbed as a data attribute like so:
```
<section class="GRIDSECTION">
<?php
query_posts('post_type=CUSTOMTYPE');
while (have_posts()) : the_post();
$postID = get_the_ID();
?>
<a class="GRIDITEM" href="#" data-post_id='<?php echo $postID; ?>' data-post_type='POST-TYPE'>
<h2><?php the_title(); ?></h2>
<span><?php the_field('CUSTOM-CONTENT');?></span>
</a>
<?php
endwhile;
?>
</section>
```
And then my AJAX script based on some of the reading I've done:
```
console.log('01 - AJAX Loaded');
$(".GRIDITEM").click(function () {
console.log('02 - AJAX Starting');
//var id_post = $(this).attr('post_id');
$.ajax({
type: 'POST',
url: '<?php echo admin_url('admin-ajax.php'); ?>',
data: {
'post_id': ?????,
'action': 'f711_get_post_content' //this is the name of the AJAX method called in WordPress
}, success: function (result) {
console.log('03a - SUCCESS');
alert(result);
},
error: function () {
alert("error");
console.log('03b - FAILURE');
}
});
});
```
I'm not sure how to connect pass the ID into the data type with this method.
I figured once I manage to get the post\_id passed in, I can do the same thing for the POST-TYPE.
What I intend to do is pass the Post ID and the Custom Post Type into Ajax to send and receive the Post that the GRIDITEM represents.
And then of course, return back to where I started.
Here's the overall feel I want to achieve.
<http://tympanus.net/Development/AnimatedGridLayout/>
But since we use custom post types and custom fields in each post, I'm not sure how to call that in. Plus I've only just started using AJAX.
Thanks!

Based on the comments, there is no foolproof way to check if someone's website has SSL set up correctly. Possible options include a setting in the plugin to have the user confirm that they have SSL set up.
However, one automated way is to check if the site URL has `https://` in it. This is assumed that SSL has been set up properly by the user since the website wouldn't load correctly if they try to set the domain with HTTPS:
```
add_action( 'template_redirect', 'wpse_241934_redirect_https', 1, 1 );
function redirect_https() {
# If 'https://' is in the website's site URL and SSL is not being used, force HTTPS
if ( preg_match( '/https:\/\//', site_url() ) && ! is_ssl() ) {
wp_redirect( 'https://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'], 301 );
exit;
}
}
```
For me, this function wouldn't be necessary since my plugin makes all URLs protocol-relative. This could still be helpful for anyone else who wants to execute a function if a website is running SSL only.

How can I hook into the head of this page for custom stylesheets and hook into the body for custom html?
|
In `functions.php` in your child theme, you can do a couple different things on the login screen. First, you'll want to add a custom stylesheet by hooking into `login_enqueue_scripts`.
```
add_action( 'login_enqueue_scripts', 'wpse_login_styles' );
function wpse_login_styles() {
wp_enqueue_style( 'wpse-custom-login', get_stylesheet_directory_uri() . '/style-login.css' );
}
```
Then you can create a `styles-login.css` file in the root of your child theme directory (or adjust the path in `wp_enqueue_script` based on your needs).
Once you've made it that far, you can customize the login page however you'd like using CSS in that file. For example, change the login logo with these instructions ripped from [the Codex](https://codex.wordpress.org/Customizing_the_Login_Form#Change_the_Login_Logo):
```
#login h1 a, .login h1 a {
background-image: url(path/to/login/logo.png);
padding-bottom: 30px;
}
```
Beyond CSS, you can also change the URL and site title on this page using the `login_headerurl` and `login_headertitle` hooks, also described in the above Codex link.
If you want to go further like adding elements to the page, or even creating a custom login page, that's all described [here](https://codex.wordpress.org/Customizing_the_Login_Form#Login_Hooks) and [here](https://codex.wordpress.org/Customizing_the_Login_Form#Make_a_Custom_Login_Page).

Can we do it on the post itself? When the visitor open the post page itself (not the homepage), only an excerpt is available and they should click on "*read more*" to view the full content.

The solution might depend on why exactly you want it to work that way on the post page. But probably the best way would be to do this on the client side.
**Method with maximum height**
Let's say your post template has its content like this:
```
<div id="content"><?php the_content(); ?></div>
```
You need to add a button after this div, so it would become:
```
<div id="content"><?php the_content(); ?></div>
<button class="show-more">Show more</button>
```
Then you add CSS to only show the content up to specific height, in your style.css add:
```
#content { max-height: 100px; overflow: hidden; }
.show-more { margin-top: 15px; }
```
Finally, add a script that would show the full height of content and remove "show-more" button after it's clicked:
```
jQuery(document).ready(function($) {
$('.show-more').click(function() {
$('#content').css('max-height', 'none');
$(this).remove();
});
});
```
It's just a basic setup, so feel free to adjust the styles and the script as you'd like.
Here's a link to the fiddle where you can try it out: <https://jsfiddle.net/psxtur2L/>
**Method with replacing the content**
If you want to specifically show the excerpt as a short version, you can do it this way.
In your template, you add both the excerpt and the content, and a button, like this:
```
<div id="excerpt"><?php the_excerpt(); ?></div>
<div id="content"><?php the_content(); ?></div>
<button class="show-more">Show more</button>
```
In CSS you just hide the content by default:
```
#content { display: none; }
.show-more { margin-top: 15px; }
```
And then you hide the excerpt and show the content when the user clicks on the button:
```
jQuery(document).ready(function($) {
$('.show-more').click(function() {
$('#excerpt').hide();
$('#content').show();
$(this).remove();
});
});
```
Here's a fiddle for that: <https://jsfiddle.net/o7z2Lsks/>
Note that the user can access full content without clicking the button if he's using browser's debugger tool, but I assume that it is not important. If you would need to make checks whether the user is logged in and so on, you should rather use AJAX, so it would require more additions to the code.

Defining Open Graph meta tags like this for images.
```
global $post;
$postImg = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), array( 1200, 9999 ), false );
<meta property="og:image" content="<?php echo $postImg[0]; ?>"/>
<meta property="og:image:width" content="<?php echo $postImg[1]; ?>"/>
<meta property="og:image:height" content="<?php echo $postImg[2]; ?>"/>
```
I get this in my website source:
```
<meta property="og:image" content="http://elpace.co/event-image.jpg"/>
<meta property="og:image:width" content="2953"/>
<meta property="og:image:height" content="4134"/>
```
But this in facebook's Open Graph debugger
(what scrapper sees).
```
<meta property="og:image" content="">
<meta property="og:image:width" content="">
<meta property="og:image:height" content="">
```
Thank You

The solution might depend on why exactly you want it to work that way on the post page. But probably the best way would be to do this on the client side.
**Method with maximum height**
Let's say your post template has its content like this:
```
<div id="content"><?php the_content(); ?></div>
```
You need to add a button after this div, so it would become:
```
<div id="content"><?php the_content(); ?></div>
<button class="show-more">Show more</button>
```
Then you add CSS to only show the content up to specific height, in your style.css add:
```
#content { max-height: 100px; overflow: hidden; }
.show-more { margin-top: 15px; }
```
Finally, add a script that would show the full height of content and remove "show-more" button after it's clicked:
```
jQuery(document).ready(function($) {
$('.show-more').click(function() {
$('#content').css('max-height', 'none');
$(this).remove();
});
});
```
It's just a basic setup, so feel free to adjust the styles and the script as you'd like.
Here's a link to the fiddle where you can try it out: <https://jsfiddle.net/psxtur2L/>
**Method with replacing the content**
If you want to specifically show the excerpt as a short version, you can do it this way.
In your template, you add both the excerpt and the content, and a button, like this:
```
<div id="excerpt"><?php the_excerpt(); ?></div>
<div id="content"><?php the_content(); ?></div>
<button class="show-more">Show more</button>
```
In CSS you just hide the content by default:
```
#content { display: none; }
.show-more { margin-top: 15px; }
```
And then you hide the excerpt and show the content when the user clicks on the button:
```
jQuery(document).ready(function($) {
$('.show-more').click(function() {
$('#excerpt').hide();
$('#content').show();
$(this).remove();
});
});
```
Here's a fiddle for that: <https://jsfiddle.net/o7z2Lsks/>
Note that the user can access full content without clicking the button if he's using browser's debugger tool, but I assume that it is not important. If you would need to make checks whether the user is logged in and so on, you should rather use AJAX, so it would require more additions to the code.

Is it possible to limit maximum menu depth in admin panel `/nav-menus.php`?
I need this because my theme won't support more than two levels of menu, so there is no point in allowing a user to make deeper menus.
|
Follow up on @jmarceli's and @squarecandy's great answers. Here is a solution that allows for:
* Easier scaling (set an object in the php action)
* Updates to the correct menu depth when the location checkboxes are changed
```
/**
* Limit max menu depth in admin panel
*/
function limit_admin_menu_depth($hook)
{
if ($hook != 'nav-menus.php') return;
wp_register_script('limit-admin-menu-depth', get_stylesheet_directory_uri() . '/js/admin/limit-menu-depth.js', array(), '1.0.0', true);
wp_localize_script(
'limit-admin-menu-depth',
'myMenuDepths',
array(
'primary' => 1, // <-- Set your menu location and max depth here
'footer' => 0 // <-- Add as many as you like
)
);
wp_enqueue_script('limit-admin-menu-depth');
}
add_action( 'admin_enqueue_scripts', 'limit_admin_menu_depth' );
```
js
```
/**
* Limit max menu depth in admin panel
* Expects wp_localize_script to have set an object of menu locations
* in the shape of { location: maxDepth, location2: maxDepth2 }
* e.g var menu-depths = {"primary":"1","footer":"0"};
*/
(function ($) {
// Get initial maximum menu depth, so that we may restore to it later.
var initialMaxDepth = wpNavMenu.options.globalMaxDepth;
function setMaxDepth() {
// Loop through each of the menu locations
$.each(myMenuDepths, function (location, maxDepth) {
if (
$('#locations-' + location).prop('checked') &&
maxDepth < wpNavMenu.options.globalMaxDepth
) {
// If this menu location is checked
// and if the max depth for this location is less than the current globalMaxDepth
// Then set globalMaxDepth to the max depth for this location
wpNavMenu.options.globalMaxDepth = maxDepth;
}
});
}
// Run the function once on document ready
setMaxDepth();
// Re-run the function if the menu location checkboxes are changed
$('.menu-theme-locations input').on('change', function () {
wpNavMenu.options.globalMaxDepth = initialMaxDepth;
setMaxDepth();
});
})(jQuery);
```

Firstly if you'd just like everyone to have to log in again you can void all of your cookies at once by changing your cookie hashes in your wordpress config file.
The lines that look like this:
```
define('AUTH_KEY', ':u(rb=Ys8*2x^rVisqX(9=10a*.euPdYEBo6p_ZBB2CDG|rv~Ju)sh+6@=L6p_:l');

define('NONCE_SALT', '.KI_*}ONxh/uwZv~!qYqOW+OL;?qvgaEqayN8>i+B.WY$e}+M9.Xqxwlf+?v 1k=');
```
[This website](https://api.wordpress.org/secret-key/1.1/salt/) is a good tool for generating new secure keys to put in.
If you want to change the amount of time you can be logged in for you can use the below code in your themes `functions.php`:
```
add_filter( 'auth_cookie_expiration', 'keep_me_logged_in_for' );
function keep_me_logged_in_for( $expirein ) {
return 86400; // time in seconds
}
```

<p>I've looked at many WP development forums but I couldn't find any answer, unfortunately. If anybody can help me. Actually, I am not sure if that kind of problem can be solved with WordPress at all. </p>
<p>My problem is the following.</p>
<p>When creating a new user in WordPress admin, the admin is offered a screen like the photo I am attaching here.</p>
<p><a href="https://i.stack.imgur.com/j66uE.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/j66uE.png" alt="Adding a new user to WordPress Admin"></a></p>
<p>After the user has already been created, the admin is redirected back to the page containing all the users.</p>
<p>My problem is, how can I add some additional tests on the user that is being created. The question is related to development of a WP plugin, php, which action hooks I can use for that purpose. I want to stay on the same page (my_domain/wp-admin/user-new.php) but after I push the 'Add New User' button, I want only the content of that page to change, the rest (I mean the admin menu on the left side to stay there) but only the content (the right area) to change (here I want to make my additional tests on that user), and showing a 'Next' button at bottom.</p>
<p>I've been thinking about adding some parameters in the URL but I do not know how to insert my code so that my problem can be solved.
I may be wrong, that was the only thing that came into my mind.
Is that possible to be implemented in WP at all? I know how to develop the pages, the only thing I cannot do is how to switch the right content but still stay on the same (add-new user-page). All the lectures I've been watching on WP plugin development, theme development, solve some not so complex problems - creating new content types, adding new menu/submenu items, and the pages related to these items, ajax and so on.</p>
<p>Could you please give me some directions(code snippets, hooks I can use), some code examples maybe, I say again, if that problem can be solved in WP at all.</p>
<p>Thank you in advance.
Best regards, George! </p>

I've been thinking about adding some parameters in the URL but I do not know how to insert my code so that my problem can be solved.
I may be wrong, that was the only thing that came into my mind.
Is that possible to be implemented in WP at all? I know how to develop the pages, the only thing I cannot do is how to switch the right content but still stay on the same (add-new user-page). All the lectures I've been watching on WP plugin development, theme development, solve some not so complex problems - creating new content types, adding new menu/submenu items, and the pages related to these items, ajax and so on.
Could you please give me some directions(code snippets, hooks I can use), some code examples maybe, I say again, if that problem can be solved in WP at all.
Thank you in advance.
Best regards, George!

Firstly if you'd just like everyone to have to log in again you can void all of your cookies at once by changing your cookie hashes in your wordpress config file.
The lines that look like this:
```
define('AUTH_KEY', ':u(rb=Ys8*2x^rVisqX(9=10a*.euPdYEBo6p_ZBB2CDG|rv~Ju)sh+6@=L6p_:l');

```
[This website](https://api.wordpress.org/secret-key/1.1/salt/) is a good tool for generating new secure keys to put in.
If you want to change the amount of time you can be logged in for you can use the below code in your themes `functions.php`:
```
add_filter( 'auth_cookie_expiration', 'keep_me_logged_in_for' );
function keep_me_logged_in_for( $expirein ) {
return 86400; // time in seconds
}
```

<p>I am using per_page instead of the filter since it is no more available. but the problem is per_page value can be between 1 and 100. what if I want to pull records and it is more that 100. per_page will not return records if the count is more than 100.
in the below API I want to pull the images which are more than 100 in count.</p>
<p><a href="http://domain_name/wp-json/wp/v2/media/?per_page=100" rel="nofollow">http://domain_name/wp-json/wp/v2/media/?per_page=100</a></p>

Add a page number query to your request URL, and continue querying next page numbers until you get an empty result:
```
<your_wordpress_install_base_url>/wp-json/wp/v2/media/?per_page=100&page=2
```
Mark's suggestion to consider requesting less than 100 per page may be a good one. So for example you may want to do your query this way:
```
<your_wordpress_install_base_url>/wp-json/wp/v2/media/?per_page=25&page=3
```
Note also that (for me at least) these query URLs work if constructed as just ~/`media?per_page=3` (instead of ~/`media/?per_page=3`). I don't know whether one or the other is preferred.
Thanks, incidentally, for the `/media/?per_page=100` part of your example. I'd been stumped about getting empty results when querying just `/media` :)

<p>I've noticed that WordPress seems a little loosey goosey when it comes to quoting styles in the HTML it generates. Sometimes WordPress uses single quotes, other times it uses double quotes</p>
<pre><code><link rel='next' title='An Example' href='http://example.com/foo/' />
<link rel="canonical" href="http://example.com/foo/" />
</code></pre>
<p>I know that single quote are, as of HTML5, technically "OK", but I'm weird and particular about how my HTML looks. Is there a way to tell WordPress to always use double quotes? If not, is there a plugin that might do this for me, or can someone point me to the appropriate do_action/apply_filter points so I can investigate this one my own?</p>

First of all, either quotes are as good as each other. See [this question](https://stackoverflow.com/questions/2373074/single-vs-double-quotes-vs)
There is no way you can do this with a plugin, action or filter. To achieve this you will have to do this manually by using the "find and replace" option on your IDE. I do not advise you to do this as:
* You may end up breaking your WordPress core
* You will lose all changes next time you will update your WordPress
* You will have to go case by case as situations like these may appear:
`echo <link rel='" . echo $bar . "' href="' . echo $foo . '";`
in which case you will have to invert double quotes for single quotes and vice versa.
This will be very time consuming for what you will get in return.
As a matter of fact WordPress coding standards accept both quotation styles:

I am trying to show a Formidable Pro Form from a WordPress site to the other.
I followed the developer's API and the REST API, but faced a CORS problem.
Then I found a suggestion on a forum thread suggesting to add this line of code the `functions.php` of the site where the original form is:
`header("Access-Control-Allow-Origin: *");`
I tried this code and it worked perfectly fine.
My question is: does this code opens security risks or other vulnerabilities?
The solution seems too simple for a problem that faces many people.
Your input is highly appreciated.

Yes, you open your site to being requested via AJAX to any other script in the whole web.
It would be better if you limit the origin to **one** specific remote domain from which you are consuming the API, like [this example](https://developer.mozilla.org/en-US/docs/Web/HTTP/Access_control_CORS#Access-Control-Allow-Origin):
```
header("Access-Control-Allow-Origin: http://mozilla.com");
```
However as the mozilla documentation states, a client can fork the origin, nevertheless limiting the sites a casual user can connect is a deterrent for some attacks.
Even better, you can limit your request to [only the methods you really need to allow](https://es.stackoverflow.com/a/20431/2162), the gist is this snippet, and it works for several domains, **if you have the `$_SERVER['HTTP_ORIGIN']` variable populated**:
```
add_action('rest_api_init', function() {
/* unhook default function */
remove_filter('rest_pre_serve_request', 'rest_send_cors_headers');
/* then add your own filter */
add_filter('rest_pre_serve_request', function( $value ) {
$origin = get_http_origin();
$my_sites = array( 'http://site1.org/', 'http://site2.net', );
if ( in_array( $origin, $my_sites ) ) {
header( 'Access-Control-Allow-Origin: ' . esc_url_raw( $origin ) );
} else {
header( 'Access-Control-Allow-Origin: ' . esc_url_raw( site_url() ) );
}
header( 'Access-Control-Allow-Methods: GET' );
return $value;
});
}, 15);
```
As you can see, this snippet uses the function [get\_http\_origin](https://developer.wordpress.org/reference/functions/get_http_origin/) provided by WordPress, but it will return null or empty, if the key `HTTP_ORIGIN` is not populated in the `$_SERVER` array, therefore it's not available to the PHP script, maybe because it is blocked by the cloudflare proxy you are using. I'd check quickly, with a script with the `<?php phpinfo(); ?>`, if you have this variable populated.
Maybe the origin site it's populated in another header by cloudflare, and you could use it in a function hooked to the `http_origin` filter. If you are lost to this point, edit your original question posting the contents of the \_SERVER variable, except your filesystem paths or passwords.
I'd be glad to help.

<p>I am attempting to create customizable theme for my clients. The goal is to enable them to modify certain styles inside the theme customizer.</p>
<p>I didn't want to insert customizer's variables inside html code, but instead created a <code>css-php</code> file. Everything works well except that live preview of the changes doesn't reflect them in real time. Instead I have to refresh the page each time after single change. It doesn't bother me personally but it annoys my clients.</p>
<p>What are your thoughts on this?</p>
<p>Thats what I have in my <code>functions.php</code>:</p>
<pre><code>function im_customize_register( $wp_customize ) {
$colors = array();
$colors[] = array(
'slug'=>'im_header_bcolor',
'default' => '#556d80',
'label' => __('Header Background Color', 'impressive')
);
$colors[] = array(
'slug'=>'im_nav_bar_bcolor',
'default' => '#434044',
'label' => __('Navigation Bar Background Color', 'impressive')
);
foreach( $colors as $color ) {
// SETTINGS
$wp_customize->add_setting(
$color['slug'], array(
'default' => $color['default'],
'type' => 'theme_mod',
'capability' =>
'edit_theme_options'
)
);
// CONTROLS
$wp_customize->add_control(

$wp_customize,
$color['slug'],

I am attempting to create customizable theme for my clients. The goal is to enable them to modify certain styles inside the theme customizer.
I didn't want to insert customizer's variables inside html code, but instead created a `css-php` file. Everything works well except that live preview of the changes doesn't reflect them in real time. Instead I have to refresh the page each time after single change. It doesn't bother me personally but it annoys my clients.
What are your thoughts on this?
Thats what I have in my `functions.php`:
```
function im_customize_register( $wp_customize ) {
$colors = array();
$colors[] = array(
'slug'=>'im_header_bcolor',
'default' => '#556d80',
'label' => __('Header Background Color', 'impressive')
);
$colors[] = array(
'slug'=>'im_nav_bar_bcolor',
'default' => '#434044',
'label' => __('Navigation Bar Background Color', 'impressive')
);
foreach( $colors as $color ) {
// SETTINGS
$wp_customize->add_setting(
$color['slug'], array(
'default' => $color['default'],
'type' => 'theme_mod',
'capability' =>
'edit_theme_options'
)
);
// CONTROLS
$wp_customize->add_control(
new WP_Customize_Color_Control(
$wp_customize,
$color['slug'],
array('label' => $color['label'],
'section' => 'colors',
'settings' => $color['slug'])
)
);
}
}
add_action( 'customize_register', 'im_customize_register' );
function im_theme_styles() {
wp_enqueue_style( 'main_css', get_template_directory_uri() . '/style.css' );
}
add_action( 'wp_enqueue_scripts', 'im_theme_styles' );
$custom_css= '
.im_header { background-color: ' . get_theme_mod('im_header_bcolor') . '; }
.im_nav_bar { background-color: ' . get_theme_mod('im_nav_bar_bcolor') . '; }
';
wp_add_inline_style ('main-style', $custom_css);
```
And my `css.php`:
```
<?php header("Content-type: text/css; charset: UTF-8"); ?>
<?php
$parse_uri = explode( 'wp-content', $_SERVER['SCRIPT_FILENAME'] );
require_once( $parse_uri[0] . 'wp-load.php' );
$im_header_bcolor = get_theme_mod('im_header_bcolor');
$im_nav_bar_bcolor = get_theme_mod('im_nav_bar_bcolor');
?>
.im_header { background-color: <?php echo $im_header_bcolor; ?>; }
.im_nav_bar { background-color: <?php echo $im_nav_bar_bcolor; ?>; }
```

You will want to put the code in the child theme, otherwise an update to the parent theme will erase it.
You want the loader to be a part of the page as the document is first loaded by the browser, then use javascript to detect when the images are finished loading and remove the loader.
Check out these resources that have more information specifically on the structure of the HTML and javascript

<p>I have a desktop app and I use <strong>$.getJSON</strong> to get data from my wordpress site using the plugin the <strong>WP REST API</strong>. This works fine and so I assume I can also make an Ajax call to a function in the functions.php? How do I do this? None of the examples I have seen supply the ajaxURL. How do I find out what this is?</p>
<p>I have the following code:</p>
<p><strong>Functions.php (in wordpress site on server)</strong></p>
<pre><code>//Called by Ajax from App - list the contents of the folder so they can be downloaded and stored locally
function folder_contents() {
$folderPath = $_POST['path'] ;
$files = array_diff(scandir($path), array('.', '..'));
print_r($files);
return $files;
die();
}
add_action('wp_ajax_my_action', 'folder_contents');
</code></pre>
<p><strong>app.js (run using node webkit locally from machine)</strong></p>
<pre><code>//ajax call
var data = {
action: 'path',
path: datafolder;
};
var ajaxurl = baseurl + ''; //WHAT IS THIS?!?!
jQuery.post(ajaxurl, data, function(response) {
alert('Got this from the server: ' + response);
console.log(response);
});
</code></pre>
<p><strong>-------------------EDIT----------------------</strong></p>
<p>After the answer below I have tried the below code based on the advice but I get </p>
<blockquote>
<p>"index.html:324 Uncaught ReferenceError: ajax_params is not defined"</p>
</blockquote>
<p><strong>Functions.php</strong> </p>
<pre><code>//add code to use ajax
function add_ajax_script() {
wp_localize_script( 'ajax-js', 'ajax_params', array( 'ajax_url' => admin_url( 'admin-ajax.php' ) ) );
}
//Called by Ajax from App - list the contents of the folder so they can be downloaded and stored locally
function folder_contents() {
$folderPath = $_POST['path'] ;
$files = array_diff(scandir($path), array('.', '..'));
wp_send_json($files);
die();
}
add_action('wp_ajax_folder_contents', 'folder_contents');
add_action('wp_ajax_nopriv_folder_contents', 'folder_contents');
add_action( 'wp_enqueue_scripts', 'add_ajax_script' );
</code></pre>
<p><strong>App.js</strong></p>
<pre><code>//ajax call

```
//ajax call
var data = {
action: 'folder_contents',
path: datafolder
};
var ajaxurl = baseurl + ''; //WHAT IS THIS?!?!
jQuery.post(ajaxurl, data, function(response) {
alert('Got this from the server: ' + response);
console.log(response);
});
```
And your PHP in functions.php
```
//Called by Ajax from App - list the contents of the folder so they can be downloaded and stored locally
function folder_contents() {
$folderPath = $_POST['path'] ;
$files = array_diff(scandir($path), array('.', '..'));
print_r($files);
return $files;
die();
}
add_action('wp_ajax_folder_contents', 'folder_contents');
add_action('wp_ajax_nopriv_folder_contents', 'folder_contents');
```
The above add your function as an ajax action. You then call the function name in your AJAX.
