You can use the remove_action() function to unhook a function from an action and then add_action() to hook it elsewhere. Note that when removing an action you must specify the tag (hook name), function, and priority exactly as it was added. Edit: Here are some additional details: You’ll have to look at the source of … Read more
What I was looking for was transition_post_status. The documentation can be found here. What I did was to add one more filter add_filter(‘transition_post_status’,’myFunction’);
That area of all admin screens is where admin notices are displayed, so you could generate an admin notice. Here’s a suitable function and hook: function wpse_233031_admin_notice() { ?> <div class=”notice notice-info”> <p>Your message here!</p> </div> <?php } function wpse_233031_hook_admin_notice() { add_action( ‘admin_notices’, ‘wpse_233031_admin_notice’ ); } add_action( ‘load-upload.php’, ‘wpse_233031_hook_admin_notice’ ); /* Edited out anonymous function … Read more
Since WP 4.6 load_theme_textdomain() (and consequently load_child_theme_textdomain()) will give priority to .mo files downloaded from WP’s online translation platform (translate.wordpress.org). Due to some new code (here, on line 769) these functions will completely ignore your local .mo files if the textdomain is found in the general languages/ directory. You can, however, use the more basic … Read more
Look at ‘save_post’ and Post Status Transitions. save_post is an action triggered whenever a post or page is created or updated, which could be from an import, post/page edit form, xmlrpc, or post by email. The data for the post is stored in $_POST, $_GET or the global $post_data, depending on how the post was … Read more
It’s triggered in wp_publish_post() that calls: wp_transition_post_status( ‘publish’, $old_status, $post ); that fires up action calls, dynamically with: do_action( “{$new_status}_{$post->post_type}”, $post->ID, $post ); where “{$new_status}_{$post->post_type}” becomes “publish_post” in your case.
Here’s the code I finally used for those interested: /* This snippet removes the action that inserts thumbnails to products in the loop * and re-adds the function customized with our wrapper in it. * It applies to all archives with products. * * @original plugin: WooCommerce * @author of snippet: Brian Krogsard */ remove_action( … Read more
Filters (and actions) need to be declared with the number of arguments accepted by the callback; it is the fourth parameter of add_filter() (default 1): add_filter( ‘nav_menu_item_args’, ‘filter_nav_menu_item_args’, 10, 3 ); function filter_nav_menu_item_args( $args, $item, $depth ) { print_r( $item ); return $args; } See add_filter() for reference.
Use do_action, you can just: do_action( ‘my_action’); if your action has a callback function that need arguments say: function my_callback( $an_array ){ //use the array for something here var_dump($an_array); } add_action( ‘my_action’, ‘my_callback’ ); you can specify it in the do_action like this: do_action( ‘my_action’, array( ‘array_for_callback’) );
If you’re wanting to replace all image markup with something custom, the best option is #2 – that way your new plugin controls everything relating to the gallery, and any future template overrides in WooCommerce will not affect it directly. If it’s just the default lightbox you want to remove you don’t actually need to … Read more
