I need to have control over the trash / delete action on a custom post type.

I need to check for some conditions and decide if i should trash the CPT or not.

The wp_trash_action hook that is fired before the trash function does not give me the option to cancel the trash procedure.

To be more specific , i need to check for a condition when the user presses TRASH. If that condition is false then i need to stop the trashing action. If it is true it should continue.

  • does not give me this option, what option? Your question is very generic. Please file an edit and explain what you exactly need to do in order to get a specific to-the-point answer. Feb 18, 2016 at 5:50

Hook onto trashed_post and use wp_untrash_post() to reverse upon meeting a condition, pseudocode example...

add_action('trashed_post', 'wpse_218031_trashed_post');

function wpse_218031_trashed_post($post_id){
   //use post_id to check conditions... if not met call:
   if ( $some_condition ) {
       wp_untrash_post($post_id);
   }
}

trashed_post runs after wp_trash_post and after the post is moved to trash.

By the way, if the constant EMPTY_TRASH_DAYS is defined and is false posts will be permanently deleted and the subsequent hooks mentioned will not be fired, in which case wp_delete_post() will be called instead.
