Remove action within a class in a parent theme’s includes folder from the child theme

Thanks a lot to Nathan Johnson: The solution was to use instance of the class the action was defined in. The class was globalized in the theme after instantiation. So the adding the below code to functions.php of a Child Theme worked: function remove_woo_forms_hooks() { global $woo_a; remove_action(‘woocommerce_before_customer_login_form’, array($woo_a,’before_customer_login_form’)); } add_action( ‘after_setup_theme’, ‘remove_woo_forms_hooks’,0);

Remove action in a parent theme from the child theme

The priority argument of add_action and remove_action need to be the same. Since wm_menu_social is hooked at 130 you need to specify 130 when removing it: remove_action( ‘tha_header_top’, ‘wm_menu_social’, 130 );

dynamic add_action according to child pages (for homepage control)

The use of add_action() seems backwards to me. A better approach would be to hook homepage_content() into the homepage hook and then just output each section within the one hook: function homepage_content() { $the_id = 5; $item = get_post( $the_id ); $page_tree_array = get_pages( array( ‘child_of’ => $the_id ) ); foreach( $page_tree_array as $item ) … Read more

Automatically set post_parent value

You can do that easily using save_post hook like so: function set_post_parent_on_save($post_id) { // If this is just a revision, don’t do anything if ( wp_is_post_revision( $post_id ) ) return; // Check if it is a post if ( ‘post’ == get_post_type( $post_id ) ) { // unhook this function so it doesn’t loop infinitely … Read more

How to remove a class function from a plugin by using remove_action()?

[ Nova_Restaurant::init(), ‘sort_menu_item_queries_by_menu_order’ ] You want something of type callable, that matches what was given when add_action. There are only a handful of valid callables: [ ‘my_function_name’ ] aka my_function_name(); [ ‘my_class_name’, ‘my_static_function’ ] aka my_class_name::my_stati_function() [ $object, ‘the_objects_function’ ] aka $object->the_objects_function [ function() {} ] an anonymous function or closure So some translation: remove_action(‘parse_query’,’WM_Nova_Restaurant’, … Read more

Get The Caller (Plugin / Theme / Core) For All actions & Hook in WordPress

Notify admin when Custom post meta data gets updated or deletet

Actually this is the right way of doing that and proper hook to work with in my opinion. All you need to do is check if the updated meta key is the one you want to detect (that’s why there are 4 arguments passed to the hook!). So let’s say your post meta is called … Read more

400 Bad Request – JavaScript App calling Custom wp-json endpoint

There were three problems I discovered with my code above. First, $_SERVER[“HTTP_REFERRER”]; is an undefined index, moreover it is mispelled – HTTP_REFERER would be correct if it could be accessed this way in WP. I found get_http_origin() instead. $data[‘UrlReferer’] = get_http_origin(); Second, I also mispelled the field I was saving this variable to – UrlReferrer … Read more

Woocommerce – Adding row to cart table

You already have the right “action”, which is woocommerce_after_cart_contents. But when I tried the markup you used: function quality_certificates(){ echo ‘<tr>TEST</tr>’; } this was the visual output: (I actually initially tested with the Twenty Seventeen theme; sorry about that. But this one is tested with Storefront) Then I started thinking that the problem might be … Read more
