I found an interesting blog post from 2015 with the following containing the "single-{$type}_template" hook:
add_filter( 'single-hats_template', function( $template ) [
if ( ! $template ) {
$template = dirname( __FILE__ ) . '/templates/default-hats-single.php';
}
return $template;
});
https://wpshout.com/hacking-the-wordpress-template-hierarchy/
That would be perfect for me as I am writing a plugin that only needs to override the template for a certain type of post.
However, I added a filter for this hook, added a breakpoint and got nothing. I couldn't find this hook in any documentation and I wonder if its since been removed?
I searched the source code, but couldn't find it being called.
I checked the global $wp_filter in the debugger and it wasn't listed.
is there a definitive way to check if a hook exists?
I am using Wordpress Version 5.6.1

i work with sportpress on Wordpress. I have a custom plugin that add a lot of function to it.
I created a template for the custom post-type of sportpress. They are in my plugin but i don't find how to make them prioritary on theme. The theme isn't a custom'one, so i don't want to delete or modify anything in it.
I have tried several things but theme's file is everytime superior.
Things tried :
naming the file 'single-....php',
filter : add_filter( 'template_include', 'toornament_template' ),
shortcode in theme file (works but not what i want...),
Thanks a lot...
EDIT :
here is what i tried exaclty, it works with another type of post that has no theme template, but not for the one that has single-post template in the theme...
add_filter( 'template_include', 'player_template', 1 );
function player_template( $template ) {
if ( is_singular( 'sp_player' ) && file_exists( plugin_dir_path(__FILE__) . 'templates/player-tpl.php' ) ){
$template = plugin_dir_path(__FILE__) . 'templates/player-tpl.php';
}
return $template;
};
I have a custom post type, and I would like to only load a stylesheet for that custom post type.
I tried to load this from the template view for the custom post type. So I tried putting it in single-joiner.php. Also, I tried putting it in functions.php.
wp_enqueue_style( 'style-joiner', get_template_directory() . '/style-joiner.css' );
Essentially, I have a variety of custom post types, and I want to run a different stylesheet for each one. Can someone point me in the right direction?
Provided you're using the default action hook for enqueuing files, wp_enqueue_scripts(), you should have access to the global $post and all of it's attributes.
Inside of your enqueuing function, you should be able to check the current post type either by making use of the is_singular() function, or referencing the global $post->post_type value.
add_action( 'wp_enqueue_scripts', 'enqueue_frontend_assets', 10 );
function enqueue_frontend_assets(){
if( is_singular( 'joiner' ) ){
wp_enqueue_style( 'style-joiner', get_stylesheet_directory_uri() . '/style-joiner.css' );
}
}
You could take it a step further and check the current post type, check to see if a style-{post_type}.css file exists, and then enqueue if it does - but if you just have the one post type, the above function should be enough to get you started.
edit: I apologize, I didn't notice before, but you're using the get_template_directory() function. That's returning a absolute system path, not the URI. You'll want to use the get_template_directory_uri() or get_stylesheet_directory_uri() functions to return the URI instead.
I've created a plugin which registers a custom post type and a custom taxonomy for me.
Now, whenever I visit: www.mysite.com/events_categories/category I should get a list of all the posts under that category. I want to use my own template and not Wordpress' default category template. Also, I want this template to be used for ALL categories, not just one category.
I used this code:
function taxonomy_template() {
global $post;
if( is_tax( 'event_categories' ) ) {
$tax_tpl = dirname( __FILE__ ) . '\taxonomy-event_categories.php';
}
return $tax_tpl;
}
add_filter( 'template_include', 'taxonomy_template' );
And while it works for the taxonomy, it makes everything else on the site go blank. This is because the $tax_tpl is empty if the page I'm on isn't a taxonomy.
I've tried using template_redirect, but no luck either.
So I want to know how to hook my template (taxonomy-event_categories.php) to the Wordpress' category template.
Hope you guys have a solution, because I've looked everywhere and it's possible to find the solution, yet I see many plugins doing this effortlessly.
Okay, so I solved it using this code:
add_action('template_redirect', 'taxonomy_template');
function taxonomy_template( ){
$tax_tpl = dirname( __FILE__ ) . '\taxonomy-event_categories.php';
if( is_tax('event_categories') ) {
include $tax_tpl;
die();
}
}
I've no idea why this works because I think I already tried this specific code, but it didn't work. Let's just hope it will keep working.
I've found a great plugin for WordPress under GPLv2 license and made a lot of changes in source code, plugin does something else now.
I modified author (with original plugin author's credits), URL, version number (from xxx 1.5 to YYY 1.0).
Everything works great, but when WordPress checks for plugin updates it treats my plugin YYY 1.0 as xxx 1.0 and displays notification about available update.
My changed plugin YYY 1.0 was installed by copying files from my computer, not from WP repository.
What else do I have to change?
Disable plugin update
Add this code in your plugin root file.
add_filter('site_transient_update_plugins', 'remove_update_notification');
function remove_update_notification($value) {
unset($value->response[ plugin_basename(__FILE__) ]);
return $value;
}
Put this code in the theme functions.php file. This is working for me and I'm using it. Also this is for specific plugin. Here you need to change plugin main file url to match to that of your plugin.
function my_filter_plugin_updates( $value ) {
if( isset( $value->response['facebook-comments-plugin/facebook-comments.php'] ) ) {
unset( $value->response['facebook-comments-plugin/facebook-comments.php'] );
}
return $value;
}
add_filter( 'site_transient_update_plugins', 'my_filter_plugin_updates' );
Here:
"facebook-comments-plugin" => facebook comments plugin folder name
"facebook-comments.php" => plugin main file.this may be different like index.php
Hope this would be help.
The simplest and effective way is to change the version of the plugin which you don't want to get update.
For an example
if I don't want wptouch to get updated, I open it's defination file, which is like:
/*
Plugin Name: WPtouch Mobile Plugin
Plugin URI: http://www.wptouch.com/
Version: 4.0.4
*/
Here in the Version change 4.0.4 to 9999
like:
/*
Plugin Name: WPtouch Mobile Plugin
Plugin URI: http://www.wptouch.com/
Version: 9999
*/
In the plugin file, there will be a function that will check for updates. The original author could have named this anything, so you will have to go through the code and check each function and what it does. I would imagine the function will be quite obvious as to what it does.
Alternatively you can add this to your plugin file:
add_filter( 'http_request_args', 'dm_prevent_update_check', 10, 2 );
function dm_prevent_update_check( $r, $url ) {
if ( 0 === strpos( $url, 'http://api.wordpress.org/plugins/update-check/' ) ) {
$my_plugin = plugin_basename( __FILE__ );
$plugins = unserialize( $r['body']['plugins'] );
unset( $plugins->plugins[$my_plugin] );
unset( $plugins->active[array_search( $my_plugin, $plugins->active )] );
$r['body']['plugins'] = serialize( $plugins );
}
return $r;
}
Credits: http://developersmind.com/2010/06/12/preventing-wordpress-from-checking-for-updates-for-a-plugin/
add_filter('site_transient_update_plugins', '__return_false');
in function.php add above code and disable all plugins updates
Add this line to wp-config.php to disable plugin updates:
define('DISALLOW_FILE_MODS',true);
One easy solution was to change the version of plugin in plugin file.
For example if plugin version is 1.2.1. You can make it like below (100.9.5 something that plugin author will never reach to )
<?php
/*
* Plugin Name: Your Plugin Name
* Description: Plugin description.
* Version: 100.9.5
*/
Here's an updated version of Mark Jaquith's script:
WP Updates have switched to HTTPS
Unserialize was blocked on my shared hosting
This uses json_decode and json_encode instead
Credit: Block Plugin Update
.
add_filter( 'http_request_args', 'widget_disable_update', 10, 2 );
function widget_disable_update( $r, $url ) {
if ( 0 === strpos( $url, 'https://api.wordpress.org/plugins/update-check/' ) ) {
$my_plugin = plugin_basename( __FILE__ );
$plugins = json_decode( $r['body']['plugins'], true );
unset( $plugins['plugins'][$my_plugin] );
unset( $plugins['active'][array_search( $my_plugin, $plugins['active'] )] );
$r['body']['plugins'] = json_encode( $plugins );
}
return $r;
}
Disable plugin updates manually:
Open functions.php file (go to your activated themes folder)
Copy and paste the following code:
remove_action( 'load-update-core.php', 'wp_update_plugins' );
add_filter( 'pre_site_transient_update_plugins', create_function( '$a', "return null;" ) );
Save changes, and you’re done
Just for completeness, here is one more plugin meant to block updates of selected other plugins:
https://github.com/daggerhart/lock-plugins
Some information about its background and mode of function can be found here (in German).
I'm trying to understand Wordpress plugin like:
apply_filters( 'gettext', $translations->translate( $text ), $text, $domain );
I'm looking for all codes in Wordpress, I can't find:
add_filter( 'gettext', ....);
Why there is no add_filter for this plugin? Or I missed something? Same thing like:
do_action('wp_loaded');
I can't find:
add_action('wp_loaded', ....);
apply_filters is like, 'if there are any filters with this name, run the attached callbacks with these parameters'. So if there is no add_filter for that name, it means that there is no filter that's going to be run with the apply_filters call at the moment.
The same goes with do_action and add_action.
I am a beginner in PHP - WordPress stack as well, but this is from my understanding.
The plugins call apply_filters without having any add_filter in their codes is to allow the website users to add custom logic to their plugins. We - the users, can add our own function and use add_filter to register our functions.
For example, this piece of code is from the plugin. Normally, it shows all products but it provides us a way to not show a specific product.
// Plugin's
if (apply_filters( 'plugin_show_products', true, $product->get_id() ) ) {
$this->show_products();
}
So, if we - the users, want to customize a bit. We can add our own function as following (maybe in functions.php)
// Our custom changes
function my_own_changes($boolean, $product_id) {
if ( $product_id === 5 ) return false;
return true;
}
add_filter( 'plugin_show_products', 'my_own_changes', 10, 2 );
This translates to: The plugin will behave normally but for my own site, it will not show the product with ID of 5!
I have come across this type of code in a plugin or theme where the apply_filter is used without necessarily having an existing filter or add_filter
In this case, where the apply_filters is used without a filter you will have to call the function again where you want to run it. For example, in the header of a theme.
The following is an example of apply filters used in a function that is again called in the header.php
if ( ! function_exists( 'header_apply_filter_test' ) ) {
function header_apply_filter_test() {
$filter_this_content = "Example of content to filter";
ob_start();
echo $filter_this_content;
$output = ob_get_clean();
echo apply_filters( 'header_apply_filter_test', $output );//used here
}
}
Now in the header.php file, you would have to call this function since it is not hooked anywhere. So, in this case, to display the output in the header you would call the function like this :
<?php header_apply_filter_test(); ?>
You could as well write this code with a hook and it would do the same thing i.e display the output in the header.
add_filter('wp_head', 'header_apply_filter_test');
if ( ! function_exists( 'header_apply_filter_test' ) ) {
function header_apply_filter_test() {
$filter_this_content = "Example of content to filter";
ob_start();
echo $filter_this_content;
$output = ob_get_clean();
echo $output;
}
}
For this second option, you would still have the capability of using apply_filters anywhere else to call the callback function header_apply_filter_test() since the filter now exists.
So the bottom line in my view is a use case since either approach works!
