php - Run when a post-type is saved run a function in wordpress -

-

i trying add_action in wordpress such when post of type 'fep_message' saved check '_fep_delete_by_' keys associated post_parent id , delete them wp_post_meta table. code built not working:

add_action('publish_post', 'undelete_thread'); function undelete_thread($post_id, $post) {     global $wpdb;     if ($post->post_type = 'fep_message'){         $participants = fep_get_participants( $post->post_parent );         foreach( $participants $participant )          {             $query ="select meta_id wp_postmeta post_id = %s , `meta_key` = '_fep_delete_by_%s'";             $queryp = $wpdb->prepare($query, array($post->post_parent, $participant));             if (!empty($queryp)) {                 delete_post_meta($queryp,'_fep_delete_by_' . $participant);              }         }     } }

what proper hook done?

use save_post hook in wordpress. can find more info here

https://codex.wordpress.org/plugin_api/action_reference/save_post

the code should changed this:

add_action('save_post', 'undelete_thread');  function undelete_thread($post_id) {     global $wpdb;     global $post;       if ($post->post_type = 'fep_message'){         $participants = fep_get_participants( $post->post_parent );         foreach( $participants $participant )          {             $query ="select meta_id wp_postmeta post_id = %s , `meta_key` = '_fep_delete_by_%s'";             $queryp = $wpdb->prepare($query, array($post->post_parent, $participant));             if (!empty($queryp)) {                 delete_post_meta($queryp,'_fep_delete_by_' . $participant);              }         }     } }
