你可以加入before_delete_post 和redirect before completing the deletion.

add_action(\'before_delete_post\', function($post_id) {

   // Get custom field
   $field = get_post_meta( $post_id, \'key\', \'true\');

   // Redirect if field is empty
   if (!$field) {
       wp_redirect(admin_url(\'edit.php\'));
       exit();
   }

}, 1);
