How can i achieve this? | WordPress way (recommended):
============================
In your plugin, use the WordPress `theme_file_path` filter hook to change the file from the plugin. Use the following CODE in your plugin:
```
add_filter( 'theme_file_path', 'wpse_258026_modify_theme_include_file', 20, 2 );
function wpse_258026_modify_theme_include_file( $path, $file = '' ) {
if( 'includes/example-file.php' === $file ) {
// change path here as required
return plugin_dir_path( __FILE__ ) . 'includes/example-file.php';
}
return $path;
}
```
Then you may include the file in your theme using the [`get_theme_file_path`](https://developer.wordpress.org/reference/functions/get_theme_file_path/) function, like this:
```
include get_theme_file_path( 'includes/example-file.php' );
```
Here, if the file is matched in the plugin's filter hook, then the plugin version of the file will be included, otherwise the theme version will be included.
Also, this way, even if the plugin is disabled, the theme will work with its own version of the file without any modification.
Controlling Page Template from Plugin:
======================================
If you are looking for controlling page templates from your plugin, then you may [check out this answer](https://wordpress.stackexchange.com/a/257674/110572) to see how to do it.
PHP way:
========
If you are including the `wp-content/theme/<your-theme>/includes/example-file.php` file using simple `include` call with **relative path** inside header, footer templates like the following:
```
include 'includes/example-file.php';
```
then it's also possible to replace it with the plugin's version of `includes/example-file.php` file using PHP `set_include_path()` function.
Generally speaking, to include a file with relative path, PHP looks for the file in the current directory. However, you can manipulate it so that PHP looks for it in another path first. In that case, use the following PHP CODE in your plugin's main PHP file to include the plugin's directory into PHP's default include path:
```
set_include_path( plugin_dir_path( __FILE__ ) . PATH_SEPARATOR . get_include_path() );
```
After that, for any `include` with relative path in `header.php`, `footer.php` etc. PHP will look for the file in your plugin's directory first.

above paragraph is quoted from WP Codex.
so you cannot use this hook to get older value because it fires after saving new values to DB. WP has another action hook named `wp_insert_post`but sadly this hook does same thing as `save_post`
alternatively you can use Filters to get the job done. WP provides few filter to edit the post while saving or before saving to DB. like [`wp_insert_post_data`](https://codex.wordpress.org/Plugin_API/Filter_Reference/wp_insert_post_data) & [`content_save_pre`](https://codex.wordpress.org/Plugin_API/Filter_Reference/content_save_pre) might work for you, i think.

| I have 10 big dropdown select combo boxes of hundreds of font-faces, including System Fonts and Google Fonts. All combo boxes carry the same values.

8. If the item is in `ggl_fonts` use it as a key to look up variants (bold, italics, etc) and subsets (languages) in `ggl_fontinfo`. Then, [dynamically add fields](http://api.jquery.com/append/) to the form.

258,109 | <p>I need the user to be able to sort and filter the posts when viewing a category. The correct way to make a category page would be to use category(-{id}/{slug}).php, but using that automatically creates a loop, so no matter what method I use to sort and filter the posts it will make another loop.</p>
<p>In that case should I make a file that's not called category(-{id}/{slug}).php and somehow link it to the categories, or would it be better to simply ignore that two loops are being made no matter what and one of them will not be used?</p>
<p>Also in that case is using the Loop again, but with the modified query, more efficient than get_posts()?</p>

| I need the user to be able to sort and filter the posts when viewing a category. The correct way to make a category page would be to use category(-{id}/{slug}).php, but using that automatically creates a loop, so no matter what method I use to sort and filter the posts it will make another loop.
In that case should I make a file that's not called category(-{id}/{slug}).php and somehow link it to the categories, or would it be better to simply ignore that two loops are being made no matter what and one of them will not be used?
Also in that case is using the Loop again, but with the modified query, more efficient than get\_posts()? | Yes, the loop and a specific category template should be used even if you want to customize the query. Why?:
1. Even with a custom page, the main query will run. So with a custom page, you are not actually avoiding the main query, you are only replacing it with a different query.
2. The main query itself is customizable.
3. If you deviate from the default WordPress behaviour, it'll be difficult for you to maintain in the future, especially it'll be difficult for other developers in case someone else takes over your work in the future.
How to modify the main query:
=============================
Fortunately, WordPress is extremely customizable, that means the main query (the loop) is also customizable. You may use the [`pre_get_posts`](https://developer.wordpress.org/reference/hooks/pre_get_posts/) action hook or [`query_posts()`](https://developer.wordpress.org/reference/functions/query_posts/) function to alter the main query. However, it's recommended to use the `pre_get_posts` hook.
For example, say you want to change the order of posts in a category based on ascending order of date. For that you may use the following CODE in your theme's `functions.php` file:
```
add_action( 'pre_get_posts', 'wpse258109_customize_category_query' );
function wpse258109_customize_category_query( $query ) {
if( ! is_admin() && $query->is_main_query() && $query->is_category( 'your-category-slug' ) ) {
// get the orderby value from where ever you want and set in the main query
$query->set( 'orderby', array( 'date' => 'ASC' ) );
}
}
```
This CODE will change the default behaviour of the main query and your category posts for `your-category-slug` archive page will load in ascending order. Of course you can make any change to this main query as you can with any custom query using the [WP\_Query](https://developer.wordpress.org/reference/classes/wp_query/) class. |

| I'd like to show 4 related posts (without a plugin) at the bottom of my blog. However, I want to exclude a certain category.
For example, if my blog post is in category `2` and `3`, I want to ignore category `2` and only look for blog posts of category `3`. Here is the relevant part of `single.php`:
***Note:*** my code below is currently not working.
```
$related = get_posts( array(
'category__in' => wp_get_post_categories( $post->ID ),
'numberposts' => 4,
'orderby' => 'date',
'post__not_in' => array( $post->ID ),
'cat' => '-2'
) );
if( $related ) {
foreach( $related as $post ) {
setup_postdata($post);
/** .. **/
}
}
```
***Update:*** Category `2` is so prevalent that I want to ignore it in the search, but not hide those results.
For example, this post is in category `2` and `3`. I want to find other posts with category `3`, and maybe they have category `2`, but I only want to search by category `3`.
***Update 2:*** I have this code below and I believe it is now working correctly:
```
$cat_ids = get_the_category();
if( ! empty( $cat_ids ) ) {
$post_cat_ids = array();
foreach( $cat_ids as $cat_id ) {

}
}
}
$related = get_posts( array(
'category__in' => wp_get_post_categories( $post->ID ),
'numberposts' => 4,
'orderby' => 'date',
'exclude' => array( $post->ID ),
'category' => $post_cat_ids
) );
``` | What I could gather from your question is:
1. You want to ignore one category (may be more) in the related post query.
2. However, you don't want to actually exclude the posts from that category (in case any post belongs to that category, but also belongs to another category you want to look for).
Based on the assumption above, you may use the following CODE (some explanation is given within the CODE in comments):
```
// set the category ID (or multiple category IDs)
// you want to ignore in the following array
$cats_to_ignore = array( 2 );
$categories = wp_get_post_categories( get_the_ID() );
$category_in = array_diff( $categories, $cats_to_ignore );
// ignore only if we have any category left after ignoring
if( count( $category_in ) == 0 ) {
$category_in = $categories;
}
$cat_args = array(
'category__in' => $category_in,
'posts_per_page' => 4,
'orderby' => 'date',
'post__not_in' => array( get_the_ID() )
);
$cat_query = new WP_Query( $cat_args );
while ( $cat_query->have_posts() ) : $cat_query->the_post();
/* just example markup for related posts */
echo '<h2><a href="' . get_the_permalink() . '">' . get_the_title() . '</a></h2>';
endwhile;
// reset $post after custom loop ends (if you need the main loop after this point)
wp_reset_postdata();
```
You cannot use `'cat' => '-2'` or `'category__not_in' => array(2)` because that will exclude all posts having category `2`, even if those posts have other categories as well. So, instead of excluding, I've ignored the category `2` in the query with this CODE: `array_diff( $categories, $cats_to_ignore );`.

258,157 | <p>I have a custom search query which I have put in a plugin. The homepage has a custom search form and when the user searches for something, it goes to the search page and displays the result.</p>
<p>My issue is that the custom query runs on every page of the website, even in the admin panel. It keeps throwing the error <code>latitude and longitude not defined</code> on every page.</p>
<p>I have used <code>is_search()</code> function to make sure the function runs only on search pages but it doesn't work. It still runs the query!</p>
<p>This is the code:</p>
<pre><code> /**

add_filter('posts_where', 'lat_lng_define');

function lat_lng_join( $join) {
global $wpdb;
if (is_search())
$join = " QUERY";
return $join;
}
//Likewise the rest of the query
</code></pre>
<p>If I isset the $GET values, the homepage shows 404:</p>
<pre><code> if(isset($_GET['latitude'] )|| isset($_GET['longitude'] )) {
$lat = sanitize_text_field( $_GET['latitude'] );
$lng = sanitize_text_field( $_GET['longitude'] );
} else {

}
</code></pre>
<p>The search query running on every page is making my website too slow. Any assistance would be appreciated.</p>

| I have a custom search query which I have put in a plugin. The homepage has a custom search form and when the user searches for something, it goes to the search page and displays the result.
My issue is that the custom query runs on every page of the website, even in the admin panel. It keeps throwing the error `latitude and longitude not defined` on every page.
I have used `is_search()` function to make sure the function runs only on search pages but it doesn't work. It still runs the query!
This is the code:
```
/**
* Custom Search on Homepage
*
*
*/
add_filter('posts_fields', 'distance_query');
add_filter('posts_where', 'lat_lng_define');
add_filter('posts_join', 'lat_lng_join');
add_filter('posts_groupby', 'having_distance');
add_filter('posts_orderby', 'sort_distance');
/**
* The Fields
*
*
*/
function distance_query( $fields ) {
global $wpdb;
//if(isset($_GET['latitude'] )|| isset($_GET['longitude'] )) {
$lat = sanitize_text_field( $_GET['latitude'] );
$lng = sanitize_text_field( $_GET['longitude'] );
//} else {
// return;
//}
if (is_search())
$fields .= ",
SOME QUERY"
return $fields;
}
/**
* The Join
*
*
*/
function lat_lng_join( $join) {
global $wpdb;
if (is_search())
$join = " QUERY";
return $join;
}
//Likewise the rest of the query
```
If I isset the $GET values, the homepage shows 404:
```
if(isset($_GET['latitude'] )|| isset($_GET['longitude'] )) {
$lat = sanitize_text_field( $_GET['latitude'] );
$lng = sanitize_text_field( $_GET['longitude'] );
} else {
return;
}
```
The search query running on every page is making my website too slow. Any assistance would be appreciated. | You are missing the curly brackets `{}` around your query statements so the query is modified regardless of the `if` statement.
So try modifying your code to have something like
```
if( is_search() ) {
$fields = '...';
return $fields
}
```
same thing with your `$join` variable
Remember that while using `if` without brackets is acceptable for single statements, it is better to always use the curly brackets. Even if it's only to make the code more consistent and easy to read for another coder (or even you in 6 months from now).

| I am trying to allow CSV files in a dashboard menu page like this..
```
<form method="post" enctype="multipart/form-data">
<input type="file" name="csv_file" id="csv_file" multiple="false" accept=".csv" />
<input type="submit" value="Upload" />
</form>
require_once( ABSPATH . 'wp-admin/includes/file.php' );
require_once( ABSPATH . 'wp-admin/includes/media.php' );
$attachment_id = media_handle_upload ( 'csv_file', 0, array(), array(
'test_form' => false,
'mimes' => array(
'csv' => 'text/csv',
),
) );
```
When I upload a CSV file to the form I get the following error message...
```
Sorry, this file type is not permitted for security reasons.
```
Can anyone spot what I am doing wrong? I had assumed I had allowed the CSV mime type in the above code. | There's a [bug](https://wordpress.org/support/topic/read-this-first-wordpress-4-7-master-list/?view=all#post-8521428) in WordPress 4.7-4.7.3 related to validating MIME types, so the code provided by Dave Romsey won't work.
There's a [plugin in the repo](https://wordpress.org/plugins/disable-real-mime-check/) that will bypass MIME checks, but it disables the checks for all users and all extensions. I think a better way would be to add a new capability for administrators that will allow them to upload .csv extensions.
```
//* Register activation and deactivation hooks
register_activation_hook( __FILE__ , 'wpse_258192_activation' );
register_deactivation_hook( __FILE__ , 'wpse_258192_deactivation' );
//* Add upload_csv capability to administrator role
function wpse_258192_activation() {
$admin = get_role( 'administrator' );
$admin->add_cap( 'upload_csv' );
}
//* Remove upload_csv capability from administrator role
function wpse_258192_deactivation() {
$admin = get_role( 'administrator' );
$admin->remove_cap( 'upload_csv' );
}
//* Add filter to check filetype and extension
add_filter( 'wp_check_filetype_and_ext', 'wpse_258192_check_filetype_and_ext', 10, 4 );
//* If the current user can upload_csv and the file extension is csv, override arguments - edit - "$pathinfo" changed to "pathinfo"
function wpse_258192_check_filetype_and_ext( $args, $file, $filename, $mimes ) {
if( current_user_can( 'upload_csv' ) && 'csv' === pathinfo( $filename )[ 'extension' ] ){
$args = array(
'ext' => 'csv',
'type' => 'text/csv',
'proper_filename' => $filename,

258,199 | <p>I added HTML banners to the top of certain pages on a client's site. He wants to make edits to the text phrases on these banners without having to edit any HTML. How do I open this up for him?

So for most styling needs, it's better to use those to generate specific CSS rule that'll only work for that widget (e.g. Search). For example, the default Search widget will have the CSS class <code>widget_search</code>. You may use it to style the search widget differently from other widgets. Like:</p>\n\n<pre><code>.widget {\n background-color: wheat;\n}\n.widget.widget_search {\n background-color: gold;\n}\n</code></pre>\n\n<h1>Option-2: Using <code>dynamic_sidebar_params</code> filter:</h1>\n\n<p>Since you are registering the widgets with <code>register_sidebar()</code> function, most likely you've used it with <code>dynamic_sidebar()</code> function in the templates. In that case, you may use the <a href=\"https://developer.wordpress.org/reference/hooks/dynamic_sidebar_params/\" rel=\"nofollow noreferrer\"><code>dynamic_sidebar_params</code></a> filter hook to insert extra CSS classes only to a specific widget.</p>\n\n<p>Use the following CODE in your theme's <code>functions.php</code> file (additional instructions are there in the CODE):</p>\n\n<pre><code>add_filter( 'dynamic_sidebar_params', 'wpse258279_filter_widget' );\nfunction wpse258279_filter_widget( $params ) {\n // avoiding admin panel\n if( ! is_admin() ) {\n if ( is_array( $params ) && is_array( $params[0] ) && $params[0]['widget_name'] === 'Search' ) {\n // Insert your custom CSS class (one or more) in the following array\n $classes = array( 'custom-css-class-for-search' );\n\n // The following three lines will add $classes\n // (along with the existing CSS classes) using regular expression\n // don't touch it if you don't know RegEx\n $pattern = '/class\\s*=\\s*([\"\\'])(?:\\s*((?!\\1).*?)\\s*)?\\1/i';\n $replace = 'class=$1$2 ' . implode( ' ', $classes ) .

So if you want to add two CSS classes for the search widget, it'll be like:</p>\n\n<pre><code>$classes = array( 'custom-css-class-for-search', 'another-class' );\n</code></pre>\n\n<h1>Option-3: Custom Widget:</h1>\n\n<p>If you need more control than the above methods can handle, then you may implement custom Widget for Search <a href=\"https://wordpress.stackexchange.com/a/258292/110572\">like shown in this answer</a>. </p>\n\n<p>However, it may be difficult to maintain custom widgets if you want the same behaviour for multiple widgets. Because then you'll have to implement that widget too (only for extra CSS class)! If that's not an issue for you, then you may follow that path, as with a custom Widget, you'll have far better control over the markups and functionality.</p>\n"

| I want to add more classes in the `div` tag of my search widget. My search is located in the sidebar together with other widgets.
My code:
```
function NT_widgets_init() {
register_sidebar( array(
'name' => __( 'Sidebar', 'side' ),
'id' => 'sidebar',
'description' => __( 'Rechte Spalte', 'rechts' ),

}
add_action( 'widgets_init', 'NT_widgets_init' );
```
So each widget gets an `id` and a `class`. How can I add more classes to only ONE widget, not the rest. | You have two possible solutions.
1. The `widget_display_callback` filter hook
--------------------------------------------
[This filter hook](http://hookr.io/filters/widget_display_callback/) parameters allows you to target easily the widget instance and override it's arguments.
A possible approach would be: Inside the filter callback, modify the arguments for that instance, display it and then **return `false`** to prevent it from being displayed again the normal way by WordPress. See this code in [wp-includes/class-wp-widget.php](https://github.com/WordPress/WordPress/blob/5f4497/wp-includes/class-wp-widget.php#L373-L399).
2. Register a new widget that extends the search widget
-------------------------------------------------------
You can extend the search widget --defined in [wp-includes/widgets/class-wp-widget-search.php](https://github.com/WordPress/WordPress/blob/dd6da7/wp-includes/widgets/class-wp-widget-search.php) and override the `widget()` method to add the class you want, something like this *(code should be added in some place seen by WordPress, like a custom plugin or in your theme `functions.php` file)*:
```
/**
* Custom widget search
*
* Extends the default search widget and adds a class to classes in `before_title`
*
* @author Nabil Kadimi
* @link http://wordpress.stackexchange.com/a/258292/17187

| I am developing a wp theme and I want to have a shortcode that can be used serveral times from within an article.
in functions.php i have:
```
function twoColPostcardfn($atts, $content){
extract(shortcode_atts(array(
'image'=>'',
'text'=>'',
'title'=>'',
'boxlink'=>'',
'float'=>''
), $atts));
$bob='<span class="twoColPostcard ">'.$content.'</span>';
return $bob;
}
add_shortcode( 'twoColPostcard', 'twoColPostcardfn' );
```
in the article I have:
```
<p>[twoColPostcard]</p>
<p>hello from the first postcard</p>
<p>[/twoColPostcard]</p>
<p>[twoColPostcard]</p>
<p>hello from the second postcard</p>
<p>[/twoColPostcard]</p>
```
And I want my output to be
```
<span class="twoColPostcard"><p>Hello from ...</p></span>
<span class="twoColPostcard"><p>Hello from ...</p></span>
```
But instead I am getting:
```
<span class="twoColPostcard">
<p></p>
<p>hello from the first postcard</p>
<p><span class="twoColPostcard "></span></p>
<p>hello from the second postcard</p>
<p></p>
</span>
```
In other words the second shortcode is begun before the first one is finished so the are ending up nested (and the 2nd one is empty)
I used the [codex](https://codex.wordpress.org/Shortcode_API#Enclosing_vs_self-closing_shortcodes) to help but its not working and I don't know why. I have tried inserting this into my functions [as per](https://wordpress.stackexchange.com/questions/175025/wraping-content-into-link-with-shortcodes) to no avail
```
remove_filter( 'the_content', 'wpautop' );
add_filter( 'the_content', 'wpautop' , 12);
``` | put the remove filter to be called first like this, change your `span` to `div` or you will have issues with some browsers:
```
remove_filter( 'the_content', 'wpautop' );
add_filter( 'the_content', 'wpautop' , 12);
function twoColPostcardfn($atts, $content){
extract(shortcode_atts(array(
'image'=>'',
'text'=>'',
'title'=>'',
'boxlink'=>'',
'float'=>''
), $atts));
$bob='<div class="twoColPostcard ">'.$content.'</div>';
return $bob;
}
add_shortcode( 'twoColPostcard', 'twoColPostcardfn' );
```
or change the content to another `span`, the `p` tag is a block tag and the `span` tag is an inline tag, a block tag cant be inside an inline one.
```
[twoColPostcard]<span>hello from the first postcard</span>[/twoColPostcard]
[twoColPostcard]<span>hello from the second postcard</span>[/twoColPostcard]

258,345 | <p>First of all thanks for reading, and my apologies for my lack of knowledge.</p>
<p>I have a WP site running with a theme and a child theme. I run it in 3 languages Spanish, English and Portuguese; and for handling the translations I'm using WPML plugin.</p>
<p>My problem is that in the translated Portfolios and Contact page the site is not looking quite as I want. After quite a lot of research on WPML support's end the conclusion was that my devs the child-theme including additional CSS sheets that are surprisingly set to post/page specific levels. So the styling goes like in the pictures:</p>

<p>And the same goes for the Contacts ID posts.</p>
<p>So in this scenario WMPL support solution is to "copy" the script and just change in the copied lines the post id.</p>
<p>I believe this is a short term solution as if in the future any of the following happen I will have to re do it again:</p>
<p>-I want to create a second Portfolio Page

<p>So the question is: Isn't another option to achieve this in a more "clean" fashion? I wouldn't know how but I imagine something like saying in the CSS, for Portfolios the styling should be these -no matter which language-; for Contact, the styling should be these, etc</p>

"text": "<h1>Why not to use ID specific CSS rules:</h1>\n\n<p>Post ID specific CSS can only be a quick fix and it's far from the best practice. Post ID is not reliable in many cases. For example:</p>\n\n<ul>\n<li><p>May be you'll delete a post and replace that with a new post.</p></li>\n<li><p>May be you'll need to migrate your site in the future to another server.</p></li>\n<li><p>May be you are creating a newer version of the post / page and want to review the new post / page before replacing the old one.</p></li>\n</ul>\n\n<p>In all these cases, post ID is likely to change and those ID specific CSS will not be even applicable any more. So you'll have to update your CSS again to match your design needs. WordPress is extremely customizable, so there is no scenario where you have to use post ID base CSS rules. For a more mature development and design practice, using ID specific CSS rules are highly discouraged. Instead, use one of the options below:</p>\n\n<h1>Use Page Templates:</h1>\n\n<p>WordPress supports <a href=\"https://developer.wordpress.org/themes/template-files-section/page-templates/\" rel=\"nofollow noreferrer\">page templates</a> for pages for a long time and from version <code>4.7</code> WordPress supports <a href=\"https://developer.wordpress.org/themes/template-files-section/page-templates/#creating-page-templates-for-specific-post-types\" rel=\"nofollow noreferrer\">page templates for any post type</a>. So if you you have WordPress <code>4.7</code> or later, then you may create specific page template for any posts or pages in your child theme.</p>\n\n<p>This way you don't need any ID specific CSS at all, because once you have those specific templates, whenever you'll need the same design for any page or post, you'll simply have to choose the same template from the post or page editor. That's all. After that, design of that page template will apply to that <code>page</code>, <code>post</code> or <code>custom post type</code>.</p>\n\n<h1>Use <a href=\"https://developer.wordpress.org/reference/hooks/post_class/\" rel=\"nofollow noreferrer\"><code>post_class</code></a> filter hook:</h1>\n\n<p>If you don't want to go to different pages or posts in the admin panel to assign specific templates (may be you have a lot of pages / posts), then you may use the <code>post_class</code> filter hook. This way, you will be able to assign unique CSS classes to different posts and pages that needs them and style them based on those CSS classes. For example, say you have a custom post type <code>movie</code> & you want different CSS class for <code>movie</code> entries. Then in your theme's <code>functions.php</code> file, you may add the following CODE:</p>\n\n<pre><code>add_filter( 'post_class', 'movie_post_class' );\nfunction movie_post_class( $class ) {\n if ( get_post_type() === 'movie' ) {\n\n // remove these CSS classes from movie entries\n $remove = array( 'css-class-to-remove', 'another-class-to-remove' );\n $class = array_diff( $class, $remove );\n\n // add these custom CSS classes to movie entries\n $add = array( 'custom-movie', 'my-movie-class' );\n $class = array_merge( $add, $class );\n }\n return $class;\n}\n</code></pre>\n\n<p>Now you can use the following CSS to target movie entires:</p>\n\n<pre><code>.custom-movie {\n background-color: gold;\n}\n</code></pre>\n\n<h1>Use <a href=\"https://developer.wordpress.org/reference/hooks/body_class/\" rel=\"nofollow noreferrer\"><code>body_class</code></a> filter hook:</h1>\n\n<p>In some situations, if you don't want to use page templates and you need more generic control over the entire page design (compared to what <code>post_class</code> will provide), then you may modify <code><body></code> class using the <code>body_class</code> filter hook (in the same way that you can do with the <code>post_class</code> filter hook). Like this:</p>\n\n<pre><code>add_filter( 'body_class', 'movie_body_class' );\nfunction movie_body_class( $class ) {\n if ( is_single() && get_post_type() === 'movie' ) {\n\n // remove these CSS classes from body class\n $remove = array( 'css-class-to-remove', 'another-class-to-remove' );\n $class = array_diff( $class, $remove );\n\n // add these custom CSS classes to body class of a movie post\n $add = array( 'custom-movie', 'my-movie-class' );\n $class = array_merge( $add, $class );\n }\n return $class;\n}\n</code></pre>\n\n<p>Now you can use the following CSS to target movie custom post page:</p>\n\n<pre><code>body.custom-movie .any-inner-content-class {\n color: blue;\n}\n</code></pre>\n\n<p>Since this custom class is added in the <code><body></code>, you can target any element within the page this way.</p>\n"

Cheers | You're absolutely right in your assumption. CSS should **never** be tied to post IDs, because they can always change (for example if you decide to migrate your posts to another install).
You can always shift control towards the admin dashboard.
Add a custom field in a post/page that you want styled in a special way (in your example you would have the same custom field in all language versions of the post/page). Let's say it will be `wpse_custom_class`. Add it to each post/page; the value will be `portfolio` for this example.
Add this code to `functions.php` (copied from [this answer](https://wordpress.stackexchange.com/a/64124/8105)). When the page loads it will look for a custom field and insert its value as a CSS class on the HTML body element.
```
function wpse_filter_post_class( $classes ) {
$my_post_class = get_post_meta($post->ID, "wpse_custom_class");
if( $my_post_class != '' ) {
$classes[] = $my_post_class;
}
return $classes;
}
add_filter( 'post_class', 'wpse_filter_post_class' );
```
Your designer can now use it like so:
```
.portfolio #content .main {
max-width: 100%;
}
```
This is more work on the admin side (you or the designer will need to manually go in and specify those CSS classes for all the custom-styled pages), but ultimately it contributes to a very flexible and future-proof solution. |

Then set the template in wordpress and no big text I see.</p>
<p>Tried the same with page.php, but nothing seems to work, I even tried editing page.php and front-page.php directly and I see nothing</p>

"text": "<h1>Why not to use ID specific CSS rules:</h1>\n\n<p>Post ID specific CSS can only be a quick fix and it's far from the best practice. Post ID is not reliable in many cases. For example:</p>\n\n<ul>\n<li><p>May be you'll delete a post and replace that with a new post.</p></li>\n<li><p>May be you'll need to migrate your site in the future to another server.</p></li>\n<li><p>May be you are creating a newer version of the post / page and want to review the new post / page before replacing the old one.</p></li>\n</ul>\n\n<p>In all these cases, post ID is likely to change and those ID specific CSS will not be even applicable any more. So you'll have to update your CSS again to match your design needs. WordPress is extremely customizable, so there is no scenario where you have to use post ID base CSS rules. For a more mature development and design practice, using ID specific CSS rules are highly discouraged. Instead, use one of the options below:</p>\n\n<h1>Use Page Templates:</h1>\n\n<p>WordPress supports <a href=\"https://developer.wordpress.org/themes/template-files-section/page-templates/\" rel=\"nofollow noreferrer\">page templates</a> for pages for a long time and from version <code>4.7</code> WordPress supports <a href=\"https://developer.wordpress.org/themes/template-files-section/page-templates/#creating-page-templates-for-specific-post-types\" rel=\"nofollow noreferrer\">page templates for any post type</a>. So if you you have WordPress <code>4.7</code> or later, then you may create specific page template for any posts or pages in your child theme.</p>\n\n<p>This way you don't need any ID specific CSS at all, because once you have those specific templates, whenever you'll need the same design for any page or post, you'll simply have to choose the same template from the post or page editor. That's all. After that, design of that page template will apply to that <code>page</code>, <code>post</code> or <code>custom post type</code>.</p>\n\n<h1>Use <a href=\"https://developer.wordpress.org/reference/hooks/post_class/\" rel=\"nofollow noreferrer\"><code>post_class</code></a> filter hook:</h1>\n\n<p>If you don't want to go to different pages or posts in the admin panel to assign specific templates (may be you have a lot of pages / posts), then you may use the <code>post_class</code> filter hook. This way, you will be able to assign unique CSS classes to different posts and pages that needs them and style them based on those CSS classes. For example, say you have a custom post type <code>movie</code> & you want different CSS class for <code>movie</code> entries. Then in your theme's <code>functions.php</code> file, you may add the following CODE:</p>\n\n<pre><code>add_filter( 'post_class', 'movie_post_class' );\nfunction movie_post_class( $class ) {\n if ( get_post_type() === 'movie' ) {\n\n // remove these CSS classes from movie entries\n $remove = array( 'css-class-to-remove', 'another-class-to-remove' );\n $class = array_diff( $class, $remove );\n\n // add these custom CSS classes to movie entries\n $add = array( 'custom-movie', 'my-movie-class' );\n $class = array_merge( $add, $class );\n }\n return $class;\n}\n</code></pre>\n\n<p>Now you can use the following CSS to target movie entires:</p>\n\n<pre><code>.custom-movie {\n background-color: gold;\n}\n</code></pre>\n\n<h1>Use <a href=\"https://developer.wordpress.org/reference/hooks/body_class/\" rel=\"nofollow noreferrer\"><code>body_class</code></a> filter hook:</h1>\n\n<p>In some situations, if you don't want to use page templates and you need more generic control over the entire page design (compared to what <code>post_class</code> will provide), then you may modify <code><body></code> class using the <code>body_class</code> filter hook (in the same way that you can do with the <code>post_class</code> filter hook). Like this:</p>\n\n<pre><code>add_filter( 'body_class', 'movie_body_class' );\nfunction movie_body_class( $class ) {\n if ( is_single() && get_post_type() === 'movie' ) {\n\n // remove these CSS classes from body class\n $remove = array( 'css-class-to-remove', 'another-class-to-remove' );\n $class = array_diff( $class, $remove );\n\n // add these custom CSS classes to body class of a movie post\n $add = array( 'custom-movie', 'my-movie-class' );\n $class = array_merge( $add, $class );\n }\n return $class;\n}\n</code></pre>\n\n<p>Now you can use the following CSS to target movie custom post page:</p>\n\n<pre><code>body.custom-movie .any-inner-content-class {\n color: blue;\n}\n</code></pre>\n\n<p>Since this custom class is added in the <code><body></code>, you can target any element within the page this way.</p>\n"

| So i'm new at wordpress, I want to add some php code in my home page, but I don't understand why neither page.php or front-page.php seems to act as a template to my homepage
I tried to copy front-page.php and I put
```
/**
* Template Name: homepagetemplate
**/
```
edited the html and add some super-big Text to see if it works....
Then set the template in wordpress and no big text I see.
Tried the same with page.php, but nothing seems to work, I even tried editing page.php and front-page.php directly and I see nothing
If I do the same with a page that is not my homepage it works if i edit page.php, but not for my homepage | You're absolutely right in your assumption. CSS should **never** be tied to post IDs, because they can always change (for example if you decide to migrate your posts to another install).
You can always shift control towards the admin dashboard.
Add a custom field in a post/page that you want styled in a special way (in your example you would have the same custom field in all language versions of the post/page). Let's say it will be `wpse_custom_class`. Add it to each post/page; the value will be `portfolio` for this example.
Add this code to `functions.php` (copied from [this answer](https://wordpress.stackexchange.com/a/64124/8105)). When the page loads it will look for a custom field and insert its value as a CSS class on the HTML body element.
```
function wpse_filter_post_class( $classes ) {
$my_post_class = get_post_meta($post->ID, "wpse_custom_class");
if( $my_post_class != '' ) {
$classes[] = $my_post_class;
}
return $classes;
}
add_filter( 'post_class', 'wpse_filter_post_class' );
```
Your designer can now use it like so:
```
.portfolio #content .main {
max-width: 100%;
}
```
This is more work on the admin side (you or the designer will need to manually go in and specify those CSS classes for all the custom-styled pages), but ultimately it contributes to a very flexible and future-proof solution. |

| Variations of this question have been asked, however the scenarios do not match mine and despite my efforts I have not been able to adopt the previous answers to a working solution in my use case.
I have a page template that has a javascript application built into it. This application uses the last parameter in a URL as a parameter for an ajax request, which it runs and then produces results for.
Due to SEO concerns and client requirement, I cannot change or alter the way this request syntax functions, so I must make it work in Wordpress (page is being converted from a Ruby application)
When the client makes a request to:
```
https://www.wordpresssite.com/service/testing-tool/domain.com
```
I need to respond with the page that is built using the template at:
```
https://www.wordpresssite.com/service/results
```
This part I have working with the following rewrite rule in `.htaccess`
```
RewriteRule ^service/testing-tool/([a-z0-9.]+)$ /index.php?pagename=service/results [NC,L]
```
The rewrite works, however WordPress changes the URL in the browser to
```
https://www.wordpresssite.com/service/results
```
This causes the JS to fail as the domain parameter is missing, and it also doesn't meet the requirements previously mentioned.
I though after doing some research here that the issue is the redirect\_canonical() action, so I tried removing it from within the template:
```
// Disable redirect_canonical()
add_action( 'init', 'results_tweaks' );
function results_tweaks()
{
remove_action( 'template_redirect', 'redirect_canonical' );
}
```

Is there another way I can override this action specifically for this template, and no others? Perhaps another way aside from removing the action? | You can use an internal rewrite instead of .htaccess:

| I spent a lot of time searching for a solution where I can pass the value of the JavaScript variable into PHP variable in the same file, same function (WordPress Widget, Form function). Is there a good way, as of 2017, to do so?
I have tried this method below. Although the Ajax part bring out the successful message, the php part failed.
**repeat.php**
```
<?php
echo $_POST['examplePHP']; //will cause undefined index here
?>
<script>
jQuery(document).ready(function($){
var exampleJS = "hi!";
$.ajax({
url: ajaxurl, //I have tried 'repeat.php' instead of ajaxurl, but not working.
type: 'POST',
data: {
examplePHP: exampleJS
},
success: function( response){
console.log("Successful!");
},
error: function(error){
console.log("error");
}
});
});
</script>
``` | I found an easy way to pass a JavaScript variable to PHP variable. Please note that this method works in WordPress version 4.7.2, and only specifically on Widget. I wrote a lot of comments to try to explain what each line did. If you have a better solution, please share with us!
**Solution:**
* Create a hidden input field to store the value of the javascript you want to pass.
* Access that hidden input field and assign its value to a PHP variable.
**Demo Widget:**
* I create a demo widget that add "LOVE YOU" word according to how many time you press the "*Add LOVE YOU*" button.
* Note that I left the hidden field shown for better understanding.
* You can change `type="text"` to`type="hidden"` to hide it.
* This demo only focuses on the `form` function of the widget.
* Make sure the click Save button, else the value of the hidden input is not saved by the widget.

``` | Well, you can create your own login form which I´ve have done also few years ago, but it is easier to do it with a plugin. there are a lot of these plugins, for example: **Auto login new user** <https://wordpress.org/plugins/auto-login-new-user-after-registration/>; also you can add **social login** to your Wordpress, this creates an automatic registration on your site. |

<p>my check out page is contain these fields (first name - last name - E-mail - phone) </p>

i hope if you explain me i didn't have any experience in PHP, CSS just i will apply your suggestions | If you at least know how to open your "functions.php" file, the following should work if you simply add it at the bottom of your functions.php file of your (child-)theme:
```
// Hook in
add_filter( 'woocommerce_checkout_fields' , 'custom_add_checkout_fields' );
// Our hooked in function - $fields is passed via the filter!
function custom_add_checkout_fields( $fields ) {
$fields['billing']['Company'] = array(
'label' => __('Company', 'woocommerce'),
'placeholder' => _x('Company Name', 'placeholder', 'woocommerce'),
'required' => true,
'class' => array('form-row-wide'),
'clear' => true
);
$fields['billing']['Position'] = array(
'label' => __('Position', 'woocommerce'),
'placeholder' => _x('Position', 'placeholder', 'woocommerce'),
'required' => true,
'class' => array('form-row-wide'),
'clear' => true
);
return $fields;
}
```
This should add the fields to the checkout page and have them be required. Then if you want to also add that information to the emails:
```
add_filter('woocommerce_email_order_meta_keys', 'my_custom_order_meta_keys');
function my_custom_order_meta_keys( $keys ) {
$keys[] = 'Company'; // This will look for a custom field called 'Company' and add it to emails
$keys[] = 'Position';
return $keys;
}
```
Snippets used from [this woocommerce doc](https://docs.woocommerce.com/document/tutorial-customising-checkout-fields-using-actions-and-filters/ "this woocommerce doc")
**PLEASE NOTE**
Adding this directly to your functions.php file of your theme and then updating your theme removes it - creating a child theme is best practice.

| I am trying to use the .htaccess file to restrict access to the wp-admin directory to an IP range as prescribed [here](https://codex.wordpress.org/Brute_Force_Attacks#Limit_Access_to_wp-admin_by_IP)
```
# Block access to wp-admin.
order deny,allow
allow from x.x.x.*
deny from all'
```
**It does precisely nothing:** I removed the allow line altogether and I am able to login just fine.
What am I missing? | I have traced the problem to a set of directions in the .conf file:
the Virtual Host was missing this:
```
<Directory "/var/www">
AllowOverride All
</Directory>
```
Which made the server to ignore .htaccess files altogether.

You've got a simple syntax error in your SQL, because of the way you're referencing the table name. You should just say
```
$sql = $wpdb->prepare( "
SELECT *

You've got a simple syntax error in your SQL, because of the way you're referencing the table name. You should just say
```
$sql = $wpdb->prepare( "
SELECT *
FROM {$wpdb->prefix}quotes
ORDER BY RAND()
LIMIT 1
");
```
and
```
$sql = $wpdb->prepare( "
SELECT *

258,664 | <p>I have placed the following Blog Loop into my 'index.php' file:</p>
<pre><code><?php
if ( have_posts() ):
while( have_posts() ): the_post();
?>
<h3><?php the_title(); ?></h3>
<p><?php the_content(); ?></p>
<small>This entry was posted on: <?php the_date('l, jS F Y'); ?> at <?php the_time('g:i a'); ?> and is filed under <?php the_category(); ?></small>

<p>On my Home page, the above code does not call any Blog Posts as I have appointed a 'Blog' page for my Blogs. That said, the above <code><small>This entry was posted on: <?php the_date('l, jS F Y'); ?> at <?php the_time('g:i a'); ?> and is filed under <?php the_category(); ?></small></code> is appearing on my Home page as well as other pages. I realise that this is because I have hard coded it into my index.php but how do I remove this. If I simply remove it from my code, it does not appear on my appointed Blog page.</p>
<p>Any suggestions?</p>

| I have placed the following Blog Loop into my 'index.php' file:
```
<?php
if ( have_posts() ):

On my Home page, the above code does not call any Blog Posts as I have appointed a 'Blog' page for my Blogs. That said, the above `<small>This entry was posted on: <?php the_date('l, jS F Y'); ?> at <?php the_time('g:i a'); ?> and is filed under <?php the_category(); ?></small>` is appearing on my Home page as well as other pages. I realise that this is because I have hard coded it into my index.php but how do I remove this. If I simply remove it from my code, it does not appear on my appointed Blog page.
Any suggestions? | I have managed to resolve the issue. The code I used, should anyone find themselves in a similar situation, is as follows:

| I want to write a cronjob for myself. But I need to get access to `WP_Query` and the permissions to delete posts etc.
My question now is, how can I include the `WP_Query` function to my own PHP file and do I need to edit or change some permissions in order to delete or create posts with that cronjob? | Load WordPress in custom PHP Script:
====================================
You need to load essential WordPress core functionality in your custom PHP script for `WP_Query` to work properly.
For example, let's say you have a custom PHP file named `my-cron.php` and WordPress is installed in the web root, like this:
```
public_html/
index.php
my-cron.php <--
wp-load.php
wp-settings.php
...
wp-admin/
wp-content/
wp-includes/
```
In this setup, if you want to use `WP_Query` in `my-cron.php` file, you need to load the `wp-load.php` file. So in `my-cron.php` file you need to have the following CODE:
```
if ( ! defined('ABSPATH') ) {
/** Set up WordPress environment */
require_once( dirname( __FILE__ ) . '/wp-load.php' );
}
```
Access WP\_Query:
=================
At this point, you'll have the access to `WP_Query`, so you can use it like this:
```
// simply selecting posts with category name "wordpress"
$the_query = new WP_Query( array( 'category_name' => 'wordpress' ) );
if ( $the_query->have_posts() ) {
echo '<ul>';
while ( $the_query->have_posts() ) {
$the_query->the_post();
echo '<li>' . get_the_title() . '</li>';
}
echo '</ul>';
}
else {
echo "No post found for category named wordpress";
}
```
Delete Posts:
=============
However, WP\_Query doesn't have delete function. For that you'll either need to use the [`wp_delete_post()`](https://developer.wordpress.org/reference/functions/wp_delete_post/) function or [`WPDB`](https://developer.wordpress.org/reference/classes/wpdb/) class. Using `wp_delete_post()` is recommended as it'll take care of many dependencies, however, if you need more control, then you may use `WPDB` class or `$wpdb` global variable, but be careful if you choose that path.
For example, the following CODE will delete the post with ID `1`:
```
$deleted = wp_delete_post( 1 );
if( $deleted === false ) {
echo "Couldn't delete Post with ID=1";
}
else {
echo "Deleted Post with ID=1";
}
```
Of course you can combine `WP_Query` with `wp_delete_post` to find and delete posts that meet specific criteria.
Setup Cron:
===========
Once you are done writing the custom PHP script, you need to [setup cron job](https://developer.wordpress.org/plugins/cron/hooking-into-the-system-task-scheduler/#mac-os-x-and-linux) to run as a HTTP request, like the following:
```
5 * * * * wget -q -O - http://your-domain.com/my-cron.php
```
Security:
=========
Since accessing `WP_Query` or `wp_delete_post` function **doesn't require any authentication** (or permission) by default, you need to make sure `my-cron.php` is not publicly accessible. For example, you can add the following at the beginning of `my-cron.php` file to give access to `localhost` only:
```
$allowed_ip = '127.0.0.1';
if( $allowed_ip !== $_SERVER['REMOTE_ADDR'] ) {
exit( 0 );
}

```
function cyhorge_check_fields( $errors, $sanitized_user_login, $user_email ) {
if ( preg_match('/(CyhorgeVH)/', $sanitized_user_login ) ) {
$errors->add( 'username_error', __( '<strong>ERROR</strong>: User contains CyhorgeVH string.', 'my_textdomain' ) );
}
return $errors;
}
add_filter( 'registration_errors', 'cyhorge_check_fields', 10, 3 );
```
[SOURCE](https://codex.wordpress.org/Plugin_API/Filter_Reference/registration_errors)
**EDIT:** Another possible solution:
```
function prevent_cyhorge_user( $user_login, $user_email, $errors ) {
if ( strpos( $user_login, 'CyhorgeVH' ) ) {
$errors->add( 'username_error', __( '<strong>ERROR</strong>: User contains CyhorgeVH string.', 'my_textdomain' ) );
}
}
add_action( 'register_post', 'prevent_cyhorge_user', 10, 3 );
```
Notice that the second function is using `strpos` instead of `preg_match` which probably a bit faster, but `preg_match` provides more flexibility if needed.
Both should work from either theme's `functions.php` or as a plugin. |

258,726 | <p>I really read a lot of articles relating adding dynamic inline stylesheet. but this one drives me crazy. i have a simple dev setup.
this is my global style:</p>
<pre><code>function bootstrap_scripts_styles() {
wp_enqueue_style( 'custom-style', get_stylesheet_directory_uri().'/style.css', array(), '2016-07-18' );
}
add_action( 'wp_enqueue_scripts', 'bootstrap_scripts_styles' );
</code></pre>
<p>because i need to trigger custom styles from single.php, i added some sample code here:</p>
<pre><code>$custom_css = ".intro { background: red; }";
wp_add_inline_style( 'custom-style', $custom_css );
</code></pre>
<p>using this, nothing happens. i don't see any inline style in frontend code. But when i debug WP_Styles() and look for "custom-style" i can see, the style is being appended:</p>
<pre><code>[custom-style] => _WP_Dependency Object
(
[handle] => custom-style
[src] => http://localhost/westerland/wp-content/themes/westerland/style.css

[args] => all
[extra] => Array
(
[after] => Array
(
[0] => .intro { background: red; }

</code></pre>
<p>so i wonder why it does not get printed?! i found a way to print it, but then, it gets printed in <code><body></code> instead right behind the <code><link></code> tag of global style:</p>
<pre><code>$custom_css = ".intro { background: red; }";
wp_add_inline_style( 'custom-style', $custom_css );
WP_Styles()->print_inline_style("custom-style");

Thanks. | According to the docs: <https://codex.wordpress.org/Using_Permalinks>
Go to settings -> permalinks -> custom structure
and change that to: `/blog/%postname%/`
But please make sure that in your custom post types definition, (`register_post_type`) set
```
'rewrite' => array( 'with_front' => false ),
```
unless the URL of all of your custom post types will be prefixed by /blog/
**UPDATE:**
As @rudtek mentioned in the comment, after your set `'with_front' => false`, you must go to settings->permalinks and hit save again to flush rewrite rules. (This is the solution for many permalink issues) |

I found some posts on the internet that suggest to hide the checkbox using css, but I would really like to disable that feature both from edit and from quick edit screen.
Any ideas? | In addition to CSS you could try to unstick each post as soon as it has been made sticky (untested):
```
add_action( 'post_stuck', function( $post_id )
{
unstick_post( $post_id );

If you're looking for another approach, than hiding it from the UI with CSS, then consider using **custom post types** instead of the `post` post type.
As far as I remember the *sticky* UI feature is only supported by the `post` post type. At least a quick look at the posts list table class, shows a check like this one:
```
if ( 'post' === $post_type && $sticky_posts = get_option( 'sticky_posts' ) ) {

258,754 | <p>When using FormData with Wordpress Admin Ajax I'm only getting back a '0' response. Usually this is because there's no action, however I'm including the action and still have the problem. I've seen similar questions on here but they all assume jQuery is being used, and in my case it isn't.</p>
<p>Javascript:</p>
<pre><code> if ($this.valid()) {
var form_data = new FormData(form);
form_data.append('security', WP.nonce);
form_data.append('action', form.action);
console.log(form.action); // console shows http://test.dev/newsletter_signup
u.jax.post(WP.ajax, form_data, onSent);
function onSent(result) {
if (result.success) {
$this.html('<p class="form-sent">' + $this.data('success') + '</p>');
} else {
$this.html('<p class="form-sent">' + result.data + '</p>');
}
}
}
</code></pre>
<p>PHP:</p>
<pre><code>add_action('wp_ajax_newsletter_signup', 'newsletter_signup');
add_action('wp_ajax_nopriv_newsletter_signup', 'newsletter_signup');
</code></pre>
<p>HTML:</p>
<pre><code><form action="newsletter_signup" class="newsletter-signup js-process-form" autocomplete="off">
<div class="field">
<label for="newsletter-email" class="field__label">Your Email Address</label>
<input type="email" class="field__input" name="email-address" id="newsletter-email" required data-msg-required="We need to know your email address" value="[email protected]">
<button type="submit" class="field__button">submit</button>
</div>
</form>
</code></pre>
<p>The only problem I can see is that the action is getting the domain appended before it. If I do this with jquery ajax, it works fine, so the code seems down to the javascript. I can provide the ajax functions but they're pretty generic.</p>
<p>If there's any more code you need, let me know.</p>
<p>Thanks.</p>
<p><strong>Edit for comments:</strong></p>
<p>I have tried changing the form to the hidden action input field as mentioned in the comments:</p>
<pre><code><form action="">
<input type="hidden" name="action" value="newsletter_signup"/>
<div class="field">
<label>Your Email Address</label>
<input type="email" name="email-address">
<button type="submit">submit</button>
</div>
</form>
</code></pre>
<p>This is the formdata sent on submit:</p>
<pre><code>------WebKitFormBoundarycskAgc8KcinCzpoG
Content-Disposition: form-data; name:"action"
newsletter_signup
------WebKitFormBoundarycskAgc8KcinCzpoG
Content-Disposition: form-data; name="email-address"
[email protected]
------WebKitFormBoundarycskAgc8KcinCzpoG--
</code></pre>
<p>And it's being sent to: </p>
<p><code>http://test.dev/wp-admin/admin-ajax.php</code></p>
<p><strong>Edit #2:</strong></p>

<pre><code>u.jax.get('http://test.dev/wp-admin/admin-ajax.php?action=newsletter_signup&email-address=t[email protected]', function(s){

});

| When using FormData with Wordpress Admin Ajax I'm only getting back a '0' response. Usually this is because there's no action, however I'm including the action and still have the problem. I've seen similar questions on here but they all assume jQuery is being used, and in my case it isn't.
Javascript:
```
if ($this.valid()) {
var form_data = new FormData(form);
form_data.append('security', WP.nonce);
form_data.append('action', form.action);
console.log(form.action); // console shows http://test.dev/newsletter_signup
u.jax.post(WP.ajax, form_data, onSent);
function onSent(result) {
if (result.success) {
$this.html('<p class="form-sent">' + $this.data('success') + '</p>');
} else {
$this.html('<p class="form-sent">' + result.data + '</p>');
}
}
}
```
PHP:
```
add_action('wp_ajax_newsletter_signup', 'newsletter_signup');
add_action('wp_ajax_nopriv_newsletter_signup', 'newsletter_signup');
```
HTML:
```
<form action="newsletter_signup" class="newsletter-signup js-process-form" autocomplete="off">
<div class="field">
<label for="newsletter-email" class="field__label">Your Email Address</label>
<input type="email" class="field__input" name="email-address" id="newsletter-email" required data-msg-required="We need to know your email address" value="[email protected]">
<button type="submit" class="field__button">submit</button>
</div>
</form>
```
The only problem I can see is that the action is getting the domain appended before it. If I do this with jquery ajax, it works fine, so the code seems down to the javascript. I can provide the ajax functions but they're pretty generic.
If there's any more code you need, let me know.
Thanks.
**Edit for comments:**
I have tried changing the form to the hidden action input field as mentioned in the comments:
```
<form action="">
<input type="hidden" name="action" value="newsletter_signup"/>
<div class="field">
<label>Your Email Address</label>
<input type="email" name="email-address">
<button type="submit">submit</button>
</div>
</form>
```
This is the formdata sent on submit:
```
------WebKitFormBoundarycskAgc8KcinCzpoG
Content-Disposition: form-data; name:"action"
newsletter_signup
------WebKitFormBoundarycskAgc8KcinCzpoG
Content-Disposition: form-data; name="email-address"
[email protected]
------WebKitFormBoundarycskAgc8KcinCzpoG--
```
And it's being sent to:
`http://test.dev/wp-admin/admin-ajax.php`
**Edit #2:**
Sending a get request like:
```
u.jax.get('http://test.dev/wp-admin/admin-ajax.php?action=newsletter_signup&email-address=t[email protected]', function(s){
console.log(s)
});
```
Also results in a response of `0`.
Here are my js ajax functions, incase it provides some clarity:
```
// ===== Ajax Utilities
// Handles Ajax Responses
function _handleResponse(request, success) {
request.onreadystatechange = function() {
if (request.status >= 200 && request.status < 400) {
if (typeof request.responseText == 'string') {
data = request.responseText;
} else {
data = JSON.parse(request.responseText);
}
success(data);
} else {
return request.status + ' failed request: '+ JSON.parse(request.responseText);
}
};
request.onerror = function() {
return request.status + ' failed request: '+ JSON.parse(request.responseText);
};
}
// Ajax GET & POST
u.jax = {
get: function(url, success) {
var request = new XMLHttpRequest();
request.open('GET', url, true);
request.send(null);
_handleResponse(request, success);
},
post: function(url, data, success) {
var request = new XMLHttpRequest();
request.open('POST', url, true);
request.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded; charset=UTF-8');
request.send(data);
_handleResponse(request, success);
}
};
```
Postman Headers for the get request:
```
Cache-Control →no-cache, must-revalidate, max-age=0
Connection →Keep-Alive
Content-Length →1
Content-Type →text/html; charset=UTF-8
Date →Fri, 03 Mar 2017 16:16:54 GMT
Expires →Wed, 11 Jan 1984 05:00:00 GMT
Keep-Alive →timeout=5, max=100
Server →Apache/2.4.20 (Unix) PHP/5.5.35 mod_wsgi/3.5 Python/3.5.1 OpenSSL/1.0.1p
X-Content-Type-Options →nosniff
X-Frame-Options →SAMEORIGIN
X-Powered-By →PHP/5.5.35
X-Robots-Tag →noindex
``` | So it turns out the only problem was the header content type.
By removing
`request.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded; charset=UTF-8');` and just leaving it out, it worked fine. That's also with the form action being grabbed and appended.
Ajax call:
```
var formData = new FormData(form);
formData.append('security', WP.nonce);
formData.append('action', form.getAttribute('action'));
u.jax.post(WP.ajax, formData, onSent);
```
Ajax Function:
```
u.jax.post = function(url, data, success) {
var request = new XMLHttpRequest();
request.open('POST', url, true);
request.send(data);
request.onreadystatechange = function() {
if (request.readyState === 4) {
if (typeof request.responseText == 'string') {
data = request.responseText;
} else {
data = JSON.parse(request.responseText);
}
success(data);
return;
}
};
}
```
Form:
```
<form action="newsletter_signup">
<div class="field">
<label>Your Email Address</label>
<input type="email" name="email-address">
<button type="submit">submit</button>
</div>
</form>
```
PHP:
```
function newsletter_signup(){
// Get the email address
$email = sanitize_email($_POST['email-address']);
// Do what you wish with the email address.
//Setup the data to send back
$data = array();
// json encode the data to send back
echo json_encode($data);
exit;
}
add_action('wp_ajax_newsletter_signup', 'newsletter_signup');
add_action('wp_ajax_nopriv_newsletter_signup', 'newsletter_signup');

258,786 | <p>I have two fields in wp_posts table that <code>wp_update_post()</code> seems to be unable to change. I'm trying to use the following code:</p>
<pre><code>$echo $group_access;
$echo $tag_list;
$my_post = array(
'ID' => 12095,
'post_title' => 'Test Title',

if (is_wp_error($post_id)) {
$errors = $post_id->get_error_messages();
foreach ($errors as $error) {

</code></pre>
<p>The <code>$group_access</code> and <code>$tag_list</code> variables echo the correct values. The <code>post_title</code> and <code>post_content</code> update correctly. <code>group_access</code> and <code>tag_list</code> do not update, and there is no error either. </p>
<p>Naturally, I've checked the table and <code>group_access</code> and <code>tag_list</code> are the correct column headers.</p>
<p>I'm baffled why it doesn't work. Is <code>wp_update_post()</code> unable to change columns that are not part of the default WP install? Is it possibly a datatype thing (e.g. I should be passing an array or integer, but I'm passing a string)?</p>

The great thing about using the <code>wp_insert_post()</code> abstraction is that it introduces a lot of action and filter hooks that we can use to modify the data before it's entered into the database. Check out the <a href=\"https://core.trac.wordpress.org/browser/tags/4.5.3/src/wp-includes/post.php#L3013\" rel=\"nofollow noreferrer\"><code>wp_insert_post()</code></a> function on trac.</p>\n"

| I have two fields in wp\_posts table that `wp_update_post()` seems to be unable to change. I'm trying to use the following code:
```
$echo $group_access;
$echo $tag_list;
$my_post = array(
'ID' => 12095,
'post_title' => 'Test Title',
'post_content' => 'Test Content',
'group_access' => $group_access,
'tag_list' => $tag_list,
);
// Update the post into the database
$post_id = wp_update_post( $my_post, true );
if (is_wp_error($post_id)) {
$errors = $post_id->get_error_messages();
foreach ($errors as $error) {
echo $error;
}
}
```
The `$group_access` and `$tag_list` variables echo the correct values. The `post_title` and `post_content` update correctly. `group_access` and `tag_list` do not update, and there is no error either.
Naturally, I've checked the table and `group_access` and `tag_list` are the correct column headers.
I'm baffled why it doesn't work. Is `wp_update_post()` unable to change columns that are not part of the default WP install? Is it possibly a datatype thing (e.g. I should be passing an array or integer, but I'm passing a string)? | You are correct; WordPress will not update custom database columns using `wp_update_post()` or `wp_insert_post()`. Instead of creating custom database columns, consider using post meta and/or taxonomy APIs.
If you must altar the `wp_posts` table, you will need to update your custom columns on your own and you may run into issues with various other plugins who don't take the custom database columns into account. |

| Google Adsense requires its activation code to be pasted right after the `<head>` tag of a site.
However, I'm using a WordPress child theme.
How can I paste my Google Adsense code in a child theme? | You can easily put your Google Adsense code within the `<head>` element of your WordPress site by using either of these methods in your `functions.php` file or by creating a plugin for that purpose:
```
/**
* Load my Google Adsense code.
*
* Here, your Google Adsense Code is stored within in your plugins directory, under the
* the file named: gads.js, which contains your Google Adsense Code.
* The full file path for the purpose below: wp-content/plugins/my-plugin-name/inc/gads.js
*/
function load_my_google_adsense_code() {
wp_enqueue_script( 'gads', plugins_url('/inc/gads.js', __FILE__), null, '', true );
}
add_action( 'wp_enqueue_scripts', 'load_my_google_adsense_code' );
```
Alternatively, you can include it directly as part of your function as below;
```
/**
* Load my Google Adsense code.
*
* Here, your Google Adsense Code is contained directly in your function.
*/
function load_my_google_adsense_code() {
?>
<script>
// Your Google Adsense Code here.
</script>
<?php
}
add_action('wp_head', 'load_my_google_adsense_code');
```
*Please note:*
The two (2) approaches above will enable you to have your Google Adsense code within the `<head>` element of your WordPress site, usually right before `</head>`, but this is really theme dependent as it depends on the placement of the `wp_head()` hook within the `header.php`.
Its generally recommended to have the `<?php wp_head(); ?>` declaration before the `</head>` which explains the point above, purposely to avoid potential conflicts with plugins among others and implemented as below:
```
<?php
/**
* The header for our theme
* File name: header.php
*/
?><!DOCTYPE html>
<html>
<head>
<!-- Other contents here -->
<?php wp_head(); ?>
</head>
<!-- Other contents may follow -->
```
As such, the options provided above will work as *Google Adsense requires, per your OP*, should your the `wp_head()` hook of your theme satisfy that condition: occurring right below your `<head>` element.
Should that not be the case and you still need to achieve this as *Google Adsense requires*, you will need to directly edit your `header.php` file for that purpose, either:
1- Putting the `wp_head()` hook right after your `<head>` element as in:
```
<?php
/**
* The header for our theme
* File name: header.php
*/
?<!DOCTYPE html>
<html>
<head>
<?php wp_head(); ?>
<!-- Other contents here -->
```
*In the above example, you will have to use either of the earlier two enumerated approaches above so as to leverage on this edit in order to achieve your goal.*
or
2- Pasting your code directly in your `header.php` file, right after your `<head>` element as in:
```
<?php
/**
* The header for our theme
* File name: header.php
*/
?<!DOCTYPE html>
<html>
<head>
<!-- Your Google Adsense code here, right after the <head> element -->
<!-- Other contents here -->
```
*Always remember to back up your files before doing such edits.* |

| How we can use function with filter to add ads before and after content,
Every ad has its priority.
How we can use parameters at function then use it at filter
This is the function
```
function mywp_before_after($content) {
if(is_page() || is_single()) {
$beforecontent = 'This goes before the content. Isn\'t that awesome!';
$aftercontent = 'And this will come after, so that you can remind them of something, like following you on Facebook for instance.';
$fullcontent = $beforecontent . $content . $aftercontent;
} else {
$fullcontent = $content;
}
return $fullcontent;
}
add_filter('the_content', 'mywp_before_after');
```
Needed
```
function mywp_before_after($content,$place,$priority) {
if ($place =='before'):
$fullcontent = $beforecontent . $content;
else:
$fullcontent =$content . $aftercontent;
}
add_filter('the_content', 'mywp_before_after',10,2,$place,$priority);
``` | You can easily put your Google Adsense code within the `<head>` element of your WordPress site by using either of these methods in your `functions.php` file or by creating a plugin for that purpose:
```
/**
* Load my Google Adsense code.
*
* Here, your Google Adsense Code is stored within in your plugins directory, under the
* the file named: gads.js, which contains your Google Adsense Code.
* The full file path for the purpose below: wp-content/plugins/my-plugin-name/inc/gads.js
*/
function load_my_google_adsense_code() {
wp_enqueue_script( 'gads', plugins_url('/inc/gads.js', __FILE__), null, '', true );
}
add_action( 'wp_enqueue_scripts', 'load_my_google_adsense_code' );
```
Alternatively, you can include it directly as part of your function as below;
```
/**
* Load my Google Adsense code.
*
* Here, your Google Adsense Code is contained directly in your function.
*/
function load_my_google_adsense_code() {
?>
<script>
// Your Google Adsense Code here.
</script>
<?php
}
add_action('wp_head', 'load_my_google_adsense_code');
```
*Please note:*
The two (2) approaches above will enable you to have your Google Adsense code within the `<head>` element of your WordPress site, usually right before `</head>`, but this is really theme dependent as it depends on the placement of the `wp_head()` hook within the `header.php`.
Its generally recommended to have the `<?php wp_head(); ?>` declaration before the `</head>` which explains the point above, purposely to avoid potential conflicts with plugins among others and implemented as below:
```
<?php
/**
* The header for our theme
* File name: header.php
*/
?><!DOCTYPE html>
<html>
<head>
<!-- Other contents here -->
<?php wp_head(); ?>
</head>
<!-- Other contents may follow -->
```
As such, the options provided above will work as *Google Adsense requires, per your OP*, should your the `wp_head()` hook of your theme satisfy that condition: occurring right below your `<head>` element.
Should that not be the case and you still need to achieve this as *Google Adsense requires*, you will need to directly edit your `header.php` file for that purpose, either:
1- Putting the `wp_head()` hook right after your `<head>` element as in:
```
<?php
/**
* The header for our theme
* File name: header.php
*/
?<!DOCTYPE html>
<html>
<head>
<?php wp_head(); ?>
<!-- Other contents here -->
```
*In the above example, you will have to use either of the earlier two enumerated approaches above so as to leverage on this edit in order to achieve your goal.*
or
2- Pasting your code directly in your `header.php` file, right after your `<head>` element as in:
```
<?php
/**
* The header for our theme
* File name: header.php
*/
?<!DOCTYPE html>
<html>
<head>
<!-- Your Google Adsense code here, right after the <head> element -->
<!-- Other contents here -->
```
*Always remember to back up your files before doing such edits.* |

258,844 | <p>I have a custom post type <code>paper</code> defined in my WordPress plugin that I show along with standard posts in the main query via:</p>
<pre><code>function add_custom_post_types_to_query( $query ) {
if ( is_home() && $query->is_main_query() )
$query->set( 'post_type', array( 'post', 'paper' ) );
// As was pointed out by Ihor Vorotnov this return is not necessary.
// return $query;
}
add_action( 'pre_get_posts', 'add_custom_post_types_to_query' );
</code></pre>
<p>I have also been able to register a custom <code>single-paper.php</code> template from the plugin directory for my post type via:</p>
<pre><code>function get_custom_post_type_single_template( $single_template ) {
global $post;
if ( $post->post_type == 'paper' ) {
$single_template = dirname( __FILE__ ) . '/single-paper.php';
}
return $single_template;
}
add_filter( 'single_template', 'get_custom_post_type_single_template' );
</code></pre>
<p>I would like to do something similar for the <code>content-____.php</code> template that is used by my theme (<code>onepress</code>) to have control over how my posts appear in the main query.</p>
<p>The <code>index.php</code> of the theme even says:</p>
<pre><code><?php /* Start the Loop */ ?>
<?php while ( have_posts() ) : the_post(); ?>
<?php
/*
* Include the Post-Format-specific template for the content.
* If you want to override this in a child theme, then include a file
* called content-___.php (where ___ is the Post Format name) and that will be used instead.
*/
get_template_part( 'template-parts/content', get_post_format() );
?>
<?php endwhile; ?>
</code></pre>
<p>but I would rather not want to implement a child theme for this and keep all the code related to the custom post type in the plugin.</p>
<p>Is there any way to add a filter such that <code>get_template_part( 'template-parts/content', get_post_format() );</code> uses a custom template supplied by my plugin for <code>paper</code> posts and the standard template of the theme for normal posts?</p>
<p>I have tried different variations of the code I used above for the <code>'single_template'</code>, but to no avail.</p>

"text": "<h1>Background</h1>\n\n<p>Unfortunately <a href=\"https://developer.wordpress.org/reference/functions/get_template_part/\" rel=\"noreferrer\"><code>get_template_part()</code></a> function doesn't have any suitable filter to achieve what you want. It's possible to use the <code>get_template_part_{$slug}</code> action hook to inject template parts, however, without any change to your theme or a child theme, the original template part will be added anyway. So this way you'll not be able to replace existing template parts.</p>\n\n<p>However, you'll be able to achieve the desired result by following one of the options below:</p>\n\n<hr>\n\n<h1>Option 1: Use the default CSS classes:</h1>\n\n<p>If only thing you want is to change the style for the <code>paper</code> custom post type, then you may simply use the generated CSS class by WordPress. Any standard theme in WordPress will generate <code>$post_type</code> and <code>type-{$post_type}</code> CSS classes for the post content. For example, the custom post type <code>paper</code> will have <code>paper</code> & <code>type-paper</code> CSS classes and general <code>post</code> will have <code>post</code> and <code>type-post</code> CSS classes. Also home page will have <code>home</code> CSS class in the body. So to target <code>paper</code> entries in the home page, you may use the following CSS rules:</p>\n\n<pre><code>body.home .type-paper {\n /* Custom CSS for paper entries in the home page */\n}\n</code></pre>\n\n<h1>Option 2: Modify CSS classes:</h1>\n\n<p>If the default CSS classes are not enough for you, you can also modify (add / remove) CSS classes using the <a href=\"https://codex.wordpress.org/Function_Reference/post_class\" rel=\"noreferrer\"><code>post_class</code></a> filter hook in your plugin. Like this:</p>\n\n<pre><code>add_filter( 'post_class', 'paper_post_class' );\nfunction paper_post_class( $class ) {\n if ( get_post_type() === 'paper' && is_home() ) {\n\n // remove these classes\n $remove = array( 'css-class-to-remove', 'another-class-to-remove' );\n $class = array_diff( $class, $remove );\n\n // add these classes\n $add = array( 'custom-paper', 'my-paper-class' );\n $class = array_merge( $add, $class );\n }\n return $class;\n}\n</code></pre>\n\n<p>This way you'll be able to remove CSS classes you don't want for <code>paper</code> entries and add new CSS classes you want for <code>paper</code> entries without modifying the theme files. Then use those CSS classes to change the style of <code>paper</code> entries as needed.</p>\n\n<hr>\n\n<h1>Option 3: Modify template & template parts</h1>\n\n<p>If your desired style change is not possible by only targeting CSS classes, then you may change the template parts from your plugin too. However, since replacing template parts added by <code>get_template_part()</code> is not possible by using hooks, you'll have to change the template in a way so that you may modify the <code>get_template_part()</code> call from within the plugin.</p>\n\n<p>To do that, you may target your <code>pre_get_posts</code> hook function and use <a href=\"https://developer.wordpress.org/reference/hooks/template_include/\" rel=\"noreferrer\"><code>template_include</code></a> filter hook to modify the home page template, like the following:</p>\n\n<pre><code>function add_custom_post_types_to_query( $query ) {\n if ( is_home() && $query->is_main_query() ) {\n $query->set( 'post_type', array( 'post', 'paper' ) );\n\n // now also change the home page template, but only when this condition matches\n add_filter( 'template_include', 'wpse258844_custom_template', 999 );\n }\n}\nadd_action( 'pre_get_posts', 'add_custom_post_types_to_query' ); \n</code></pre>\n\n<p>Then use the following CODE (modify as you need):</p>\n\n<pre><code>// for better file management, use a separate \"theme-{$theme_name_slug}\" directory within your plugin directory\n// so if the active theme name is \"OnePress\", the directory name will be \"theme-onepress\"\n// This will save you a ton of headache if you change the theme,\n// as different themes may use different function calls within the templates, which other themes may not have\ndefine( 'wpse258844_TEMPLATE_DIR', plugin_dir_path( __FILE__ ) . sprintf( 'theme-%s/', sanitize_title( wp_get_theme() ) ) );\n\nfunction wpse258844_custom_template( $template ) {\n // this file will replace your homepage template file\n $index_paper = wpse258844_TEMPLATE_DIR . 'custom-home.php';\n\n // file_exists() check may need clearing stat cache if you change file name, delete the file etc.\n // Once you are done, comment out or remove clearstatcache(); in production\n clearstatcache();\n\n if ( file_exists( $index_paper ) ) {\n $template = $index_paper;\n }\n return $template;\n}\n\nfunction wpse258844_get_template_part( $slug, $name = null ) {\n if( get_post_type() === 'paper' ) {\n\n // just to be consistant with get_template_part() function\n do_action( \"get_template_part_{$slug}\", $slug, $name );\n\n $located = '';\n $name = (string) $name;\n\n // file_exists() check may need clearing stat cache if you change file name, delete the file etc.\n // Once you are done, comment out or remove clearstatcache(); in production\n clearstatcache();\n\n if ( '' !== $name && file_exists( wpse258844_TEMPLATE_DIR . \"{$slug}-{$name}.php\" ) ) {\n $located = wpse258844_TEMPLATE_DIR . \"{$slug}-{$name}.php\";\n }\n else if ( file_exists( wpse258844_TEMPLATE_DIR . \"{$slug}.php\" ) ) {\n $located = wpse258844_TEMPLATE_DIR . \"{$slug}.php\";\n }\n\n if ( '' != $located ) {\n load_template( $located, false );\n return;\n }\n }\n\n get_template_part( $slug, $name );\n}\n</code></pre>\n\n<p>Once you have the above CODE in your plugin (read the comments within the CODE):</p>\n\n<ol>\n<li><p>Create a new directory within you plugin directory to keep theme template files, e.g. <code>theme-onepress</code>. This will help you in the future if you want to test design changes with a different theme (I suppose that's the main purpose of all these mess ;) ).</p></li>\n<li><p>Within the new <code>theme-onepress</code> directory, create a file named <code>custom-home.php</code>. Copy the CODE of home page template from your theme (may be <code>index.php</code>, or <code>home.php</code> or whatever your theme is using for the home page template). </p></li>\n<li><p>Now in <code>custom-home.php</code> change all the call of <code>get_template_part</code> to <code>wpse258844_get_template_part</code>. No need to change the parameter, only function name. <code>wpse258844_get_template_part()</code> function in the above CODE is identical to <code>get_template_part()</code> function and falls back to default behaviour if custom template part is not found within your plugin's <code>theme-{$theme_name_slug}</code> (e.g. <code>theme-onepress</code>) directory.</p></li>\n<li><p>Finally, replace whatever template part file you wanted to replace in your plugin's <code>theme-{$theme_name_slug}</code> directory.</p>\n\n<p>For example, if the original call was <code>get_template_part( 'template-parts/content', get_post_format() )</code> and you want to replace <code>content.php</code> template part, then simply place a file named <code>content.php</code> in your plugin's <code>theme-onepress/template-parts</code> directory. That means, the <code>theme-onepress</code> directory will behave like a child theme for template parts - i.e. simple drop-in replacement.</p></li>\n</ol>\n"

All that is left to do is to install a suitable template to the theme directory in a way so that it does not get overwritten or deleted when the theme is updated (we want to keep all the code well contained inside the plugin!). This can be done my putting a suitable template into the fiel <code>content-aside.php</code> in the plugins directory and hooking into `'upgrader_process_complete' as follows</p>\n\n<pre><code>function install_aside_template_on_upgrade( $upgrader_object, $options ) {\n if ($options['type'] == 'theme' ) {\n $content_aside = plugin_dir_path( __FILE__ ) .

| I have a custom post type `paper` defined in my WordPress plugin that I show along with standard posts in the main query via:
```
function add_custom_post_types_to_query( $query ) {
if ( is_home() && $query->is_main_query() )
$query->set( 'post_type', array( 'post', 'paper' ) );
// As was pointed out by Ihor Vorotnov this return is not necessary.
// return $query;
}
add_action( 'pre_get_posts', 'add_custom_post_types_to_query' );
```
I have also been able to register a custom `single-paper.php` template from the plugin directory for my post type via:
```
function get_custom_post_type_single_template( $single_template ) {
global $post;
if ( $post->post_type == 'paper' ) {
$single_template = dirname( __FILE__ ) . '/single-paper.php';
}
return $single_template;
}
add_filter( 'single_template', 'get_custom_post_type_single_template' );
```
I would like to do something similar for the `content-____.php` template that is used by my theme (`onepress`) to have control over how my posts appear in the main query.
The `index.php` of the theme even says:
```
<?php /* Start the Loop */ ?>
<?php while ( have_posts() ) : the_post(); ?>
<?php
/*
* Include the Post-Format-specific template for the content.
* If you want to override this in a child theme, then include a file
* called content-___.php (where ___ is the Post Format name) and that will be used instead.
*/
get_template_part( 'template-parts/content', get_post_format() );
?>
<?php endwhile; ?>
```
but I would rather not want to implement a child theme for this and keep all the code related to the custom post type in the plugin.
Is there any way to add a filter such that `get_template_part( 'template-parts/content', get_post_format() );` uses a custom template supplied by my plugin for `paper` posts and the standard template of the theme for normal posts?
I have tried different variations of the code I used above for the `'single_template'`, but to no avail. | Background
==========
Unfortunately [`get_template_part()`](https://developer.wordpress.org/reference/functions/get_template_part/) function doesn't have any suitable filter to achieve what you want. It's possible to use the `get_template_part_{$slug}` action hook to inject template parts, however, without any change to your theme or a child theme, the original template part will be added anyway. So this way you'll not be able to replace existing template parts.
However, you'll be able to achieve the desired result by following one of the options below:
---
Option 1: Use the default CSS classes:
======================================
If only thing you want is to change the style for the `paper` custom post type, then you may simply use the generated CSS class by WordPress. Any standard theme in WordPress will generate `$post_type` and `type-{$post_type}` CSS classes for the post content. For example, the custom post type `paper` will have `paper` & `type-paper` CSS classes and general `post` will have `post` and `type-post` CSS classes. Also home page will have `home` CSS class in the body. So to target `paper` entries in the home page, you may use the following CSS rules:
```
body.home .type-paper {
/* Custom CSS for paper entries in the home page */
}
```
Option 2: Modify CSS classes:
=============================
If the default CSS classes are not enough for you, you can also modify (add / remove) CSS classes using the [`post_class`](https://codex.wordpress.org/Function_Reference/post_class) filter hook in your plugin. Like this:
```
add_filter( 'post_class', 'paper_post_class' );
function paper_post_class( $class ) {
if ( get_post_type() === 'paper' && is_home() ) {
// remove these classes
$remove = array( 'css-class-to-remove', 'another-class-to-remove' );
$class = array_diff( $class, $remove );
// add these classes
$add = array( 'custom-paper', 'my-paper-class' );
$class = array_merge( $add, $class );
}
return $class;
}
```
This way you'll be able to remove CSS classes you don't want for `paper` entries and add new CSS classes you want for `paper` entries without modifying the theme files. Then use those CSS classes to change the style of `paper` entries as needed.
---
Option 3: Modify template & template parts
==========================================
If your desired style change is not possible by only targeting CSS classes, then you may change the template parts from your plugin too. However, since replacing template parts added by `get_template_part()` is not possible by using hooks, you'll have to change the template in a way so that you may modify the `get_template_part()` call from within the plugin.
To do that, you may target your `pre_get_posts` hook function and use [`template_include`](https://developer.wordpress.org/reference/hooks/template_include/) filter hook to modify the home page template, like the following:
```
function add_custom_post_types_to_query( $query ) {
if ( is_home() && $query->is_main_query() ) {
$query->set( 'post_type', array( 'post', 'paper' ) );
// now also change the home page template, but only when this condition matches
add_filter( 'template_include', 'wpse258844_custom_template', 999 );
}
}
add_action( 'pre_get_posts', 'add_custom_post_types_to_query' );
```
Then use the following CODE (modify as you need):
```
// for better file management, use a separate "theme-{$theme_name_slug}" directory within your plugin directory
// so if the active theme name is "OnePress", the directory name will be "theme-onepress"
// This will save you a ton of headache if you change the theme,
// as different themes may use different function calls within the templates, which other themes may not have
define( 'wpse258844_TEMPLATE_DIR', plugin_dir_path( __FILE__ ) . sprintf( 'theme-%s/', sanitize_title( wp_get_theme() ) ) );
function wpse258844_custom_template( $template ) {
// this file will replace your homepage template file
$index_paper = wpse258844_TEMPLATE_DIR . 'custom-home.php';
// file_exists() check may need clearing stat cache if you change file name, delete the file etc.
// Once you are done, comment out or remove clearstatcache(); in production
clearstatcache();
if ( file_exists( $index_paper ) ) {
$template = $index_paper;
}
return $template;
}
function wpse258844_get_template_part( $slug, $name = null ) {
if( get_post_type() === 'paper' ) {
// just to be consistant with get_template_part() function
do_action( "get_template_part_{$slug}", $slug, $name );
$located = '';
$name = (string) $name;
// file_exists() check may need clearing stat cache if you change file name, delete the file etc.
// Once you are done, comment out or remove clearstatcache(); in production
clearstatcache();
if ( '' !== $name && file_exists( wpse258844_TEMPLATE_DIR . "{$slug}-{$name}.php" ) ) {
$located = wpse258844_TEMPLATE_DIR . "{$slug}-{$name}.php";
}
else if ( file_exists( wpse258844_TEMPLATE_DIR . "{$slug}.php" ) ) {
$located = wpse258844_TEMPLATE_DIR . "{$slug}.php";
}
if ( '' != $located ) {
load_template( $located, false );
return;
}
}
get_template_part( $slug, $name );
}
```
Once you have the above CODE in your plugin (read the comments within the CODE):
1. Create a new directory within you plugin directory to keep theme template files, e.g. `theme-onepress`. This will help you in the future if you want to test design changes with a different theme (I suppose that's the main purpose of all these mess ;) ).
2. Within the new `theme-onepress` directory, create a file named `custom-home.php`. Copy the CODE of home page template from your theme (may be `index.php`, or `home.php` or whatever your theme is using for the home page template).
3. Now in `custom-home.php` change all the call of `get_template_part` to `wpse258844_get_template_part`. No need to change the parameter, only function name. `wpse258844_get_template_part()` function in the above CODE is identical to `get_template_part()` function and falls back to default behaviour if custom template part is not found within your plugin's `theme-{$theme_name_slug}` (e.g. `theme-onepress`) directory.
4. Finally, replace whatever template part file you wanted to replace in your plugin's `theme-{$theme_name_slug}` directory.
For example, if the original call was `get_template_part( 'template-parts/content', get_post_format() )` and you want to replace `content.php` template part, then simply place a file named `content.php` in your plugin's `theme-onepress/template-parts` directory. That means, the `theme-onepress` directory will behave like a child theme for template parts - i.e. simple drop-in replacement. |

Thanks in advance | The two problems you describe may very well be related. Attachments (images) [are stored as posts in the database](https://codex.wordpress.org/Using_Image_and_File_Attachments) (so title, caption and so on can be stored in relation to the physical image file). It is this post that you see in the image library.
Normally, the `post_status` of attachments is `inherit`. However, if the `post_status` is set as `draft` the post won't be visible in the media library anymore, even as the physical file is still there and the title/caption is still stored in the database.
So, my guess is that either malware or a rogue/ill-programmed plugin has set all you `post_statusses` to `draft`. To find out, you should open your PHP Admin, and check the `post_status` column in the `_posts` table of your database. If there aren't a lot of images you can change the `post_status` manually to make the image posts reappear in the image library (try at least one the check if this solves your problem). Else you'll have to run an SQL query on the table. |

Thank you already! | If I correctly understand the question you're asking, you don't want your CPT to be directly available on the front-end. If so, then just set `'public' => false` when you register the post\_type.

| I am a newbie who recently start working on XAMPP and I am unable to access wp-admin on XAMPP server localhost. While installing WordPress, it asked me for user name and password too but when I am trying to access wp-admin with username and password, it says "INVALID USER NAME". As far as I know, I am putting the correct username and password here.
Please suggest how to login back and where will I get the correct user details.
Thanks | I would add a filter to the body class in your functions.php file. This will add a class based on the page/post/cpt slug:
**PHP:**
```
/**
*
* Add Page/Post Body Class Slug
*
* post-slug-for-post
* page-slug-for-page
*
*
*/
function yourprefix_page_slug_body_class( $classes ) {
global $post;
if ( isset( $post ) ) {
$classes[] = $post->post_type . '-' . $post->post_name;
}
return $classes;
}
add_filter( 'body_class', 'yourprefix_page_slug_body_class' );
```
Then I would use jQuery to swap the src based on the body class. You will need to change the path variable and possibly the parent class where the logo img is located (the example uses `.site-branding`).
**jQuery**
```
( function( window, $, undefined ) {
'use strict';
$( document ).ready( function( ) {
/* ==== change logo based on body class ===
// default logo and path
var path = 'http://yourdomain.com/wp-content/uploads/',
logo = 'logo-1.png'; // this is the default
// logo 2 conditional change var value
if ( $( 'body' ).is( '.page-such-and-such' ) ) {
logo = 'logo-2.png';
}
// logo 3 conditional change var value
if ( $( 'body' ).is( '.post-such-and-thing' ) ) {
logo = 'logo-3.png';
}
// return the logo src
$( '.site-branding img' ).attr( 'src', path + logo );
// end swapping logo
} ); //* end ready
} )( this, jQuery );
```

259,007 | <p>How do I change the height of the header image (specified in the Header Media section) in the Twenty Seventeen Theme?</p>
<p>Specifically I want to change it on the home page because here it fills up nearly the entire page. I want it to be much shorter. The way it appears on other pages such as the built-in About page has a good height so if I could mimic that on the home page I would be satisfied. Although knowing how to do precise control would be great.</p>

There is code that applies when the admin bar *is not* visible (typical anonymous user) currently at line 3629
```
.twentyseventeen-front-page.has-header-image .custom-header-media,
.twentyseventeen-front-page.has-header-video .custom-header-media,
.home.blog.has-header-image .custom-header-media,
.home.blog.has-header-video .custom-header-media {
height: 1200px;
height: 100vh;
max-height: 100%;
overflow: hidden;
}
```
And code that applies when the admin bar *is* visible (e.g. you are logged in) currently at line 3646
```
.admin-bar.twentyseventeen-front-page.has-header-image .custom-header-media,
.admin-bar.twentyseventeen-front-page.has-header-video .custom-header-media,
.admin-bar.home.blog.has-header-image .custom-header-media,
.admin-bar.home.blog.has-header-video .custom-header-media {
height: calc(100vh - 32px);
}
```
And then code that applies on mobile currently at line 1638:
```
.has-header-image.twentyseventeen-front-page .custom-header,
.has-header-video.twentyseventeen-front-page .custom-header,
.has-header-image.home.blog .custom-header,
.has-header-video.home.blog .custom-header {
display: table;
height: 300px;
height: 75vh;
width: 100%;
}
```
By copying these three sections of css into my child theme's style.css and modifying the `height` attribute I was able to tweak the height for the header image on the home page. I set the height to `30vh`, `calc(30vh - 32px)`, and `30vh` respectively in each section. I left the first `height: 1200px` alone.
Note the height element is set at `100vh` which sizes the height relative to the viewport height. So 100vh is 100% of the viewport while 50vh is 50% of the viewport.
One odd thing is that on the home page the zoom and position of the header image is different than on other pages.
Not sure if this is the best way. I'm open to better options but so far it's working at a basic level. |

The submodule setup adds the wp-content files to site\_url.com/content
ie site\_url.com/content/themes site\_url.com/content/plugins etc
Within my wp-config I have
```
define('WP_CONTENT_URL', 'http://site_url.com/content');
define('WP_CONTENT_DIR', realpath($_SERVER['DOCUMENT_ROOT'] . '/content'));
```
This has always worked before, I feel as though Im just making a silly mistake somewhere.
Ive checked the DB and the site\_url and home are set correctly.
Any ideas on what I may have missed?
Thanks
Nad | I'm giving possible cases from the top of my head:
***Case 1:*** May be it's related to [`realpath()`](http://php.net/manual/en/function.realpath.php) function. `realpath()` acts differently in different OS. Also, it returns `false` if the web server user doesn't have executable permission on the corresponding directory. There are some other problems too, so better try this:
```
// change it based on the location of wp-config.php file
define( 'WP_CONTENT_DIR', dirname( __FILE__ ) . '/content' );
```
***Case 2:*** May be the `sage-master` theme directory actually doesn't exist or it's not accessible by the web server user.
***Case 3:*** May be the directories exist but have character case different. Unix systems have case sensitive file system, but windows is case insensitive. So it may work on windows but not on Unix for this reason.
There may be other issues, so better activate debugging in WordPress and check what errors you get. |

So I cannot understand WHY this action is fired just entering the page... causing my nonce check to fail. | When you choose "Your CPT > Add New", WP calls [get\_default\_post\_to\_edit()](https://developer.wordpress.org/reference/functions/get_default_post_to_edit/), which actually creates an "empty" post (with `'post_status' => 'auto-draft'`) and then calls [wp\_insert\_post()](https://developer.wordpress.org/reference/functions/wp_insert_post/). This is what is causing your `save_datasheet_meta()` function to be called before you think it should.
Hence, generally you should add some additional sanity checks to the beginning of any func you hook into `save_post`, ala:
```
function
save_datasheet_meta ($post_id, $post)
{
if ('auto-draft' == $post->post_status) {
// bail, because your nonce will not be set at this point
return ;
}
// post{,-new}.php enqueue some JS which periodically saves the post_content,
// but NOT any post_meta
// so, a `save_post` hook func that only cares about updating post_meta should
// bail when DOING_AUTOSAVE is true
if (defined ('DOING_AUTOSAVE') && DOING_AUTOSAVE) {
return ;
}
$nonce = wp_verify_nonce ( plugin_basename(__FILE__), 'datasheet_meta_nonce');
if (!$nonce) {

[`wp_update_post()`](https://core.trac.wordpress.org/browser/tags/4.7/src/wp-includes/post.php#L3534) calls some hooks that `$wpdb` doesn't on it's own. You'll have to do it on your own to make it compatible with other plugins.
2. `wp_update_post()` calls some functions related to database entry sanitation, thumbnails, attachments, time (format, zone etc.), comment, taxonomy, meta, cache etc. So if you use `$wpdb`, make sure you handle all of them as appropriate.
3. WordPress will update `wp_update_post()` to always keep it compatible with the current state of Database, core CODE, plugin support etc. Even if you do everything right, future updates will be difficult for you with `$wpdb`.
So if something can be done with `wp_update_post()`, then always use it, only use `$wpdb` if your desired action related to updating post can't be done with it. |

I am using ACF version 4.4.11
The repeater is not empty.
What can be the problem? | The functions.php file doesn't know where you want that code to be shown on the front end. You need to put the code into a template page (ie the woocommerce account page) or attach it to that page with a woocommerce hook to the template.
You'll need to add it into a function to properly work if you decide it's better to leave it in your functions.php. In either case you may want to surround the while statement in an if statement in case there are no rows. Otherwise you'll get errors.
Lastly since you're echoing the field you should use
```
echo get_sub_field('email_group_id');
```
if you actually have more code than what you provided, and it's in the options page i would add the "option" argument to the field as well:
```
while ( have_rows('group_email' , 'option') ) : the_row();
?>
<option>
<?php
echo get_sub_field('email_group_id', 'option');
?>
</option>
<?php
endwhile;
```
It may be worth trying that first. |
259,128 | <p>Didn't thought I would have to ask this question. But yes, it's true. It seems you can't have a separate child menu in Wordpress?</p>
<p>I'm absolutely not a beginner on Wordpress. Have worked and developed in it for years.</p>
<p>However, it might be possible to do a big walkaround to get the separate child/sub menu. But what I would like to get an answer of here is more like; </p>
<p><strong>Is it really true there's no simple built-in solution?</strong></p>
<p>I have really searched on this site and other sites for answers but struggled to find an answer. It seems to be all about drop downs. I'm soooo tired of drop downs now!</p>
<p>Can say I'm running Woocommerce as well. But no, there was no answer in their's documentation either. A lot about "secondary menus". But that's not the same. I need the parent child relationship.</p>
<p><h2>EDIT:</h2><strong>Following code example and output example has been added/changed to work as an example of a case scenario:</strong></p>
<p>Here is my code:</p>
<pre><code> <nav class="parent">

'theme_location' => 'primary',
'container_class' => 'primary-navigation',
)
);
?>

Edit 2:

First problem is that `depth` attribute doesn't seems to work for `wp_nav_menu()`. Can't have just top level? | Found [the solution](https://christianvarga.com/how-to-get-submenu-items-from-a-wordpress-menu-based-on-parent-or-sibling/). Put this in your **function.php** file:
```
// add hook
add_filter( 'wp_nav_menu_objects', 'my_wp_nav_menu_objects_sub_menu', 10, 2 );
// filter_hook function to react on sub_menu flag
function my_wp_nav_menu_objects_sub_menu( $sorted_menu_items, $args ) {
if ( isset( $args->sub_menu ) ) {
$root_id = 0;
// find the current menu item
foreach ( $sorted_menu_items as $menu_item ) {
if ( $menu_item->current ) {
// set the root id based on whether the current menu item has a parent or not
$root_id = ( $menu_item->menu_item_parent ) ? $menu_item->menu_item_parent : $menu_item->ID;
break;
}
}
// find the top level parent
if ( ! isset( $args->direct_parent ) ) {
$prev_root_id = $root_id;
while ( $prev_root_id != 0 ) {
foreach ( $sorted_menu_items as $menu_item ) {
if ( $menu_item->ID == $prev_root_id ) {
$prev_root_id = $menu_item->menu_item_parent;
// don't set the root_id to 0 if we've reached the top of the menu
if ( $prev_root_id != 0 ) $root_id = $menu_item->menu_item_parent;
break;
}
}
}
}
$menu_item_parents = array();
foreach ( $sorted_menu_items as $key => $item ) {
// init menu_item_parents
if ( $item->ID == $root_id ) $menu_item_parents[] = $item->ID;
if ( in_array( $item->menu_item_parent, $menu_item_parents ) ) {
// part of sub-tree: keep!
$menu_item_parents[] = $item->ID;
} else if ( ! ( isset( $args->show_parent ) && in_array( $item->ID, $menu_item_parents ) ) ) {
// not part of sub-tree: away with it!
unset( $sorted_menu_items[$key] );
}
}
return $sorted_menu_items;
} else {
return $sorted_menu_items;
}
}
```
Then use it this way:
```
<?php
wp_nav_menu(
array(
'theme_location' => 'primary',
'container_class' => 'primary-navigation',
'depth' => 1
)
);
wp_nav_menu(
array(
'theme_location' => 'primary',
'container_class' => 'primary-child-navigation',
'sub_menu' => true
)
);
?>

| I have some very basic data that I am posting to a proprietary lead capturing system. Whenever I submit my form data to their system the body of the request is an error 500 page.
I am trying to debug the problem with their developer, it clearly doesn't like something in my query string, and he would like to be able to test it on his end.
However, I've scoured through Google results and the WordPress codex and I cannot find a way to pull the query string that is generated from something like:
>
> $result = wp\_remote\_get( 'thirdparty.com', array( 'body' => array(
> 'foo' => 'bar' ) ) );

I would expect the query string to look something like:
```
thirdparty.com?foo=bar
```
Anyone have any tip on how to get this generated URL/query string? | While the other answers are pretty good in providing an answer to your question (how to get the generated url), i will answer what i guess you really want to know (how do i get it to call thirdparty.com?foo=bar with wp\_remote\_get)
The Answer is: the $args array you use to transmit the url parameters won't work like this. If you have to transmit a POST request with wp\_remote\_post, you would use the body argument like your example. However, to wp\_remote\_get thirdparty.com?foo=bar, you simply do
```
wp_remote_get('http://thirdparty.com?foo=bar');
```
if you want to get fancy and use an array, you can also do this:
```
$url = "http://thirdparty.com";
$data = array('foo' => 'bar');
$query_url = $url.'?'.http_build_query($data);
$response = wp_remote_get($query_url);
```

| I am trying to create a custom meta box that lets you add rows dynamically. Following code snippet works fine and and saves data in my edit page section. However, I can't get it to display the data on the actual page:
```
add_action( 'add_meta_boxes', 'dynamic_add_custom_box' );
/* Do something with the data entered */
add_action( 'save_post', 'dynamic_save_postdata' );
/* Adds a box to the main column on the Post and Page edit screens */
function dynamic_add_custom_box() {
add_meta_box(
'dynamic_sectionid',
__( 'My Tracks', 'myplugin_textdomain' ),
'dynamic_inner_custom_box',
'page');
}
/* Prints the box content */
function dynamic_inner_custom_box() {
global $post;
// Use nonce for verification
wp_nonce_field( plugin_basename( __FILE__ ), 'dynamicMeta_noncename' );
?>
<div id="meta_inner">
<?php
//get the saved meta as an arry
$songs = get_post_meta($post->ID,'songs',true);
$c = 0;
if ( count( $songs ) > 0 ) {
foreach( $songs as $track ) {
if ( isset( $track['title'] ) || isset( $track['track'] ) ) {
printf( '<p>Song Title <input type="text" name="songs[%1$s][title]" value="%2$s" /> -- Track number : <input type="text" name="songs[%1$s][track]" value="%3$s" /><span class="remove">%4$s</span></p>', $c, $track['title'], $track['track'], __( 'Remove Track' ) );
$c = $c +1;
}
}
}
?>
<span id="here"></span>
<span class="add"><?php _e('Add Tracks'); ?></span>
<script>
var $ =jQuery.noConflict();
$(document).ready(function() {
var count = <?php echo $c; ?>;
$(".add").click(function() {
count = count + 1;
$('#here').append('<p> Song Title <input type="text" name="songs['+count+'][title]" value="" /> -- Track number : <input type="text" name="songs['+count+'][track]" value="" /><span class="remove">Remove Track</span></p>' );
return false;
});
$(".remove").live('click', function() {
$(this).parent().remove();
});
});
</script>
</div><?php
}
/* When the post is saved, saves our custom data */
function dynamic_save_postdata( $post_id ) {
// verify if this is an auto save routine.
// If it is our form has not been submitted, so we dont want to do anything
if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE )
return;
// verify this came from the our screen and with proper authorization,
// because save_post can be triggered at other times
if ( !isset( $_POST['dynamicMeta_noncename'] ) )
return;
if ( !wp_verify_nonce( $_POST['dynamicMeta_noncename'], plugin_basename( __FILE__ ) ) )
return;
// OK, we're authenticated: we need to find and save the data
$songs = $_POST['songs'];
update_post_meta($post_id,'songs',$songs);
}
```
As you can see, 'page' is referring to page where I want to post to. Now when I loop for the results on the page template nothing shows up.
```
<?php
$args = array(
'post_type' => 'page',
);
$repeat_loop = new WP_Query( $args ); if ( $repeat_loop->have_posts() ) : while ( $repeat_loop->have_posts() ) : $repeat_loop->the_post();
$meta = get_post_meta( $post->ID, 'songs', true ); ?>
<?php echo $meta['title']; ?><?php echo $meta['track']; ?>
<?php endwhile;
endif;
wp_reset_postdata();
?>
```
I do get results when I use the 'var\_dump($posts);'. I just can't get it to display in the page. | Try changing `$meta['title']` to `$meta['title'][0]` & the same thing for `$meta['track']` . change it to `$meta['track'][0]`
**UPDATE:**
I looked at the code more deeply and you basically need a foreach loop.
Here's the final code should look like:
```
<?php
$args = array(
'post_type' => 'page'
);
$repeat_loop = new WP_Query( $args ); if ( $repeat_loop->have_posts() ) : while ( $repeat_loop->have_posts() ) : $repeat_loop->the_post();
$meta = get_post_meta( $post->ID, 'songs', true ); ?>
<?php
foreach ($meta as $key => $value) {
echo $value['title']; ?><?php echo $value['track'];
}
?>
<?php endwhile;
endif;
wp_reset_postdata();
?>
```

I think you are doing it right. If the parent theme is attaching the function responsible for enqueueing its styles to the `wp_enqueue_scripts` hook, then your `bla_enqueue_child_theme_styles()` function must be being executed first (because you passed `-20` as priority) and your styles should be being included first in the page's source code.
The fact that Materialize's CSS rules are overriding the parent theme's may not be related to the order in which the stylesheets are being included, but to the specificity of the selectors being used in those stylesheets.
Cake is likely to be using some kind of CSS framework as well, either one developed by a third party or a custom one. In that case, is very likely that both Cake and Materialize are trying to solve the same problems, but using different methods, creating conflicts in the process. |

| Wordpress renders a meta description tag with the content of the blog post as the value for the description.
I already generated in the `header.php` what I want the description to be, no matter what. However, the old one is still in there. I checked `single-post.php` and `header.php` and there is nothing rendering the meta description. So it HAS to be the `wp_head()` function.
Is there anyway I can put something in my `functions.php` or something to ensure that on certain pages the meta description is removed from `wp_head()`? | You should be able to remove the existing description tag with the following code:

259,416 | <p>I have a custom post template on which I want to show a list of other children of this post's parent. I already have the parent post ID in a variable ($parent_artist_id), which is being used elsewhere on the page. Here is my code:</p>

| I wanted to know if there were any ways to easily hide a selected user's user page. I've yet to find any code that does so. I've only found code to remove all user pages.
Thanks | I'm assuming you want to hide the author page on the site itself (and not in `wp-admin`).
To do that, just create a new template file called `author-{$id}.php`, where `{$id}` is replaced by the ID of the author you want to hide. So if the author ID is `6`, the template file should be called `author-6.php`.
Inside the new file, put this in:
```
<?php
header( "HTTP/1.1 301 Moved Permanently" );
wp_redirect( get_home_url() );
exit;
?>
```
Now when you try to load the author's page, it will just redirect to the site visitor to your home page.

| There is the following hierarchical taxonomy structure of a specific post:
* Term A
+ SubTerm A.1
+ SubTerm A.2
- SubTerm A.2.1
* Term B
+ SubTerm B.1
- SubTerm B.1.1
- SubTerm B.1.2
How to display
1. all parent terms (result: A, B)
2. all second level terms (result: A.1, A.2, B.1)
3. all third level terms (result: A.2.1, B.1.1, B.1.2) | I love a good challenge!
The function here:
```
function get_post_categories_sorted ( $post_id ){
$terms = wp_get_post_terms( $post_id, 'category' );
$sorted_terms = [];
foreach( $terms as $term ){
$depth = count( get_ancestors( $term->term_id, 'category' ) );
if( ! array_key_exists( $depth, $sorted_terms ) ){
$sorted_terms[$depth] = [];
}
$sorted_terms[$depth][] = $term;
}
return $sorted_terms;
}
```
will give you an array with the structure in the following image. `$sorted_terms[0]` contains the top level terms, `$sorted_terms[1]` all the second level term and so on.
[](https://i.stack.imgur.com/7bXgI.png)
It would definitely be worth using a cache or the transients API to store the data as it could get expensive with a lot of terms to sort through as the call to get\_ancestors involves a call back to the database for each level it has to traverse back up the chain.
**EDIT**
You can use this something like the following:
```
$sorted_terms = get_post_categories_sorted( get_the_ID() );
foreach( $sorted_terms as $key => $level_items ){
$number = $key + 1;
echo sprintf( '<p>Level %s Categories</p>', $number );
echo '<ul>';
foreach( $level_items as $term ){
echo sprintf( '<li>%s</li>', $term->name );
}
echo '</ul>';
}
```
**EDIT 2**
To just use a specific level, you can simplify the code above like this:
```
$sorted_terms = get_post_categories_sorted( get_the_ID() );
echo '<p>Level 1 Categories</p>';
echo '<ul>';
//Change the 0 here to whatever level you need,
//just remember is is 0 based; IE the first level is 0, 2nd level is 1 etc.
//If the number doesn't exist, PHP will throw an undefined index error.
foreach( $sorted_items[0] as $term ){
echo sprintf( '<li>%s</li>', $term->name );
}
echo '</ul>';

```
something
else
```
And in the HTML:
```
<span>something</span>
<br />
<span>else</span>

Than I also used the `the_content` filter but with `strtr()` like this:
```
function remove_br_from_shortcodes($content){
// look for the string "]<br />" and replace it just with "]"
$replace = array (
']<br />' => ']'
);
$content = strtr($content, $replace);
return $content;
}
add_filter('the_content', 'remove_br_from_shortcodes');
```
After refreshing the page, the frontend now shows:
```
something else
```
In the HTML:
```
<span>something</span>
<span>else</span>
```
As the name of `the_content` filter already suggests, it is a filter for the *normal post/page content*, not, for example text-widgets or excerpts.
If you also want to remove paragraphs (`<p>`) than please try adding this in the `$replace` array: (watch your comma´s!)
```
'<p>[' => '[',
']</p>' => ']',
```
With the PHP `strtr()` function, you can replace certain characters in a string. [More to read here.](https://www.w3schools.com/php/func_string_strtr.asp) |

| I'm trying to figure out how to retrieve a user's roles from the API, but I haven't been able to sort it. Is this information not accessible by default?
Can anyone point me in the right direction? | This is totally possible by registering your own rest field into the response.
Here's some documentation on modifying response data.
<https://developer.wordpress.org/rest-api/extending-the-rest-api/modifying-responses/>
Here's how to add roles to the endpoint:
```
function get_user_roles($object, $field_name, $request) {
return get_userdata($object['id'])->roles;
}
add_action('rest_api_init', function() {
register_rest_field('user', 'roles', array(
'get_callback' => 'get_user_roles',
'update_callback' => null,
'schema' => array(
'type' => 'array'
)
));
});
```
Specifically, what I'm doing is creating a function called `get_user_roles` that retrieves the user roles, then registering a 'roles' field in the response, and tell it that the data comes from that function.
I also ran into an issue of it not playing nice when the data returned an `array`, so I told the schema to expect it in the `schema` property of the array passed in `register_rest_field` |

P.S. I'm using WP 4.7.3 | I found a better workaround using the same filter suggested by @ben-casey in [his answer](https://wordpress.stackexchange.com/a/259592/109855).
Firstly I registered throuhg `register_rest_field` all the custom fields of all the user types I have in the database.

Thanks. | To Add External Atylesheet:
===========================
Generally speaking, you should use the [`wp_enqueue_style()`](https://developer.wordpress.org/reference/functions/wp_enqueue_style/) function to add external stylesheet to your theme.
```
function wpse259600_add_style() {
wp_enqueue_style( 'theme_critical', get_template_directory_uri() . '/css/critical.css', array(), '1.0.0' );
}
add_action( 'wp_enqueue_scripts', 'wpse259600_add_style' );
```
---
To Add Internal Stylesheet:
===========================
However, if (for whatever reason) you have to add internal stylesheet (i.e. printing the entire CSS file within the HTML `<head>` tag using the `<style>` tag), then you may use `inclue_once` like below:
```
add_action( 'wp_head', 'wpse259600_internal_css_print' );
function wpse259600_internal_css_print() {
echo '<style type="text/css">';
// this will also allow you to use PHP to create dynamic css rules
include_once get_template_directory() . '/css/critical.css';
echo '</style>';
}
```
This will not generate warning in [`theme check`](https://wordpress.org/plugins/theme-check/). Although, I wouldn't recommend this. If you want to add custom CSS this way, you better save it to the database with customizer theme options and then add it with `wp_add_inline_style` function along with your theme's main CSS file. |

I've done some research, but there isn’t any direct function that counts only the images. What is the most simple way to do this? | There's a handy [built-in function](https://developer.wordpress.org/reference/functions/wp_count_attachments/), namely `wp_count_attachments()`.
We can filter out images with `wp_count_attachments( $mime_type = 'image' )` that returns an object like:
```
stdClass Object
(
[image/gif] => 9
[image/jpeg] => 121
[image/png] => 20
[image/x-icon] => 6
[trash] => 0
)
```
So we can use the one-liner:
```
$count = array_sum( (array) wp_count_attachments( $mime_type = 'image' ) );
```
for the total number of images. |

I did this by simply copying post_categories_meta_box and deleting that button.</p>\n<p><strong>My custom function:</strong></p>\n<pre><code>function custom_post_categories_meta_box_without_add_new( $post, $box ) {\n $defaults = array( 'taxonomy' => 'category' );\n if ( ! isset( $box['args'] ) || ! is_array( $box['args'] ) ) {\n $args = array();\n } else {\n $args = $box['args'];\n }\n $parsed_args = wp_parse_args( $args, $defaults );\n $tax_name = esc_attr( $parsed_args['taxonomy'] );\n $taxonomy = get_taxonomy( $parsed_args['taxonomy'] );\n ?>\n <div id="taxonomy-<?php echo $tax_name; ?>" class="categorydiv">\n <ul id="<?php echo $tax_name; ?>-tabs" class="category-tabs">\n <li class="tabs"><a href="#<?php echo $tax_name; ?>-all"><?php echo $taxonomy->labels->all_items; ?></a></li>\n <li class="hide-if-no-js"><a href="#<?php echo $tax_name; ?>-pop"><?php echo esc_html( $taxonomy->labels->most_used ); ?></a></li>\n </ul>\n \n <div id="<?php echo $tax_name; ?>-pop" class="tabs-panel" style="display: none;">\n <ul id="<?php echo $tax_name; ?>checklist-pop" class="categorychecklist form-no-clear" >\n <?php $popular_ids = wp_popular_terms_checklist( $tax_name ); ?>\n </ul>\n </div>\n \n <div id="<?php echo $tax_name; ?>-all" class="tabs-panel">\n <?php\n $name = ( 'category' === $tax_name ) ?

| I would like to disable the "+Add Category Button" under the Category metabox so that anyone creating a post has to choose only from the list of existing categories.
1. I did check out another post, which literally has the same question,
[How To Remove The "+ Add New Category" Link From A Category Metabox](https://wordpress.stackexchange.com/questions/29140/how-to-remove-the-add-new-category-link-from-a-category-metabox)
But the accepted answer doesn't make sense because he references Line 345-367, which are not relevant lines (maybe because of WP updates, things might have changed). So I am confused.
2. I installed the 'User Role Editor' plugin and removed the 'manage\_categories' capability for the 'Editor' which worked. But I would like to remove it for ALL users including admin, superadmin. So I tried changing the theme's functions.php as:
```
add_action( 'add_meta_boxes', 'isa_remove_categories_meta_box' )
function isa_remove_categories_meta_box() {
remove_meta_box( 'categorydiv', 'post', 'side' );// remove the Categories box
}
```
But, this makes the entire Category box disappear. Is there anything I can use to replace the 'categorydiv' to make only the '+Add New Category' disappear?
Or, can someone point me out to what the accepted answer from the other post meant by lines 345-367? I can try that as well. | >

If removing the 'manage\_categories' capability from the editor role provides the functionality you want, then you can remove the 'manage\_categories' capability from all user roles fairly easily either by using an existing plugin, or writing a new plugin that upon activation removes the capability from all the user roles. Here's the code that would be necessary to remove the capability from each role (actually, it explicitly sets the capability to false).
```
register_activation_hook( __FILE__, 'wpse_259647_remove_manage_categories_cap' );
function wpse_259647_remove_manage_categories_cap() {
$roles = wp_roles();
foreach( $roles->role_names as $slug => $name ) {
$role = get_role( $slug );
$role->add_cap( 'manage_categories', false );
}
}
```
This won't remove the capability from "super admins" though since "super admins" technically aren't a role or a capability.
If you want to explicitly revoke the manage\_categories capability from all users, you could do that too.
```
register_activation_hook( __FILE__, 'wpse_259647_remove_manage_categories_cap' );
function wpse_259647_remove_manage_categories_cap() {
$users = get_users();
foreach( $users as $user ) {
$user->add_cap( 'manage_categories', false );
}
}
```
This may still not remove the capability from "super admins" though, because WordPress treats them differently than other users. |
