The action is update_option_permalink_structure. You get the old and the new value as parameters. add_action( ‘update_option_permalink_structure’ , ‘my_custom_function’, 10, 2 ); function my_custom_function( $oldvalue, $_newvalue ) { // do something } There are also the actions update_option_category_base and update_option_tag_base.
There is a global variable called $pagenow for the use within WP Admin: global $pagenow; if ( $pagenow == ‘upload.php’ ) : function custom_admin_notice() { echo ‘<div class=”updated”><p>Updated!</p></div>’; } add_action( ‘admin_notices’, ‘custom_admin_notice’ ); endif; UPDATE: Simply include the snippet in your themes or plugins functions.php
The name of the current hook is always current_filter(). Despite its name, this function returns the name of actions too. Usage example: Move the textarea in a comment form. The current priority is: key( $GLOBALS[‘wp_filter’][ $hook ] ).
It’s done the same way you would do in procedural, you need to provide the priority and the number of parameters so you would have; add_filter(‘wp_get_attachment_image_src’, array($this, ‘useCDN’), 10, 3); to pass 3 additional parameters to the filter
The ‘body’ needs to be an array, not including the ‘json_encode($user)’ piece. $response = wp_remote_post( ‘myapp.com/endpoint’, array( ‘method’ => ‘POST’, ‘headers’ => array(‘Content-Type’ => ‘application/json; charset=utf-8’), ‘body’ => $user ) ); I have this in my function since I also had issues with the body being an object: if (is_object($user) && !is_array($user)) $user = json_decode(json_encode($user), … Read more
register_post_type function should be executed every time a WP request is made. Default post types don’t have this requirement. You can use your code as is, in MU plugin. Just create a .PHP file with this code, and place it in mu-plugins sub-folder of wp-content. You don’t need to provide any standard plugin headers.
I found the magic code you need. Use current_filter(). This function will return name of the current filter or action. add_action(‘my_test_hook_1′,’my_test_callback_function’); add_action(‘my_test_hook_2′,’my_test_callback_function’); add_action(‘my_test_hook_3′,’my_test_callback_function’); add_action(‘my_test_hook_4′,’my_test_callback_function’); function my_test_callback_function(){ $called_action_hook = current_filter(); // ***The magic code that will return the last called action echo “This function is called by action: ” . $called_action_hook ; } For reference: https://developer.wordpress.org/reference/functions/current_filter/
Use is_home instead, as is_page_template will not work for home.php as its technically not a page template in the traditional sense. add_action(‘template_redirect’, ‘are_we_home_yet’, 10); function are_we_home_yet(){ if ( is_home() ) { //your logic here } } Revised: add_action(‘template_redirect’, ‘are_we_home_yet’, 10); function are_we_home_yet(){ global $template; $template_file = basename((__FILE__).$template); if ( is_home() && $template_file=”home.php” ) { //do … Read more
Don’t ask me way but i actually have a function to count hooked functions to a tag /** * count_hooked_functions * @author Ohad Raz * @param string $tag hook name as string * @return int the number of hooked functions to a specific hook */ function count_hooked_functions($tag = false){ global $wp_filter; if ($tag){ if (isset($wp_filter[$tag])){ … Read more
There is no real difference between the two methods. When using method A, only the hooking is bound to the condition (i.e., the function is defined no matter what), while in method B the definition of the function as well as the hooking is. Another thing is the following method (which you did not include): … Read more
