php – Important Error customiser

Ive efficiently added all posts (of a customized publish sort) to my wordpress menu utilizing this technique:Right here

The whole lot is working nice. Sadly once I view the customiser, I get the “crucial error on this web site” message, it exhibits up on the preview ache, the admin navigation is seen nevertheless.

That is what I’ve in my features file:

/**
* auto_child_page_menu
*/
/* Sub menu */
add_filter( 'wp_get_nav_menu_items', 'cpt_locations_filter', 12, 3 );

perform cpt_locations_filter( $objects, $menu, $args ) {
  if ( is_admin() ) { return $objects; }
  $child_items = array(); 
  $menu_order = rely($objects); 
  $parent_item_id = 0;

  foreach ( $objects as $merchandise ) {
    if ( in_array('history-menu', $item->lessons) ){
        $parent_item_id = $item->ID;
    }
  }

  if($parent_item_id > 0){

      foreach ( get_posts( 'post_type=historical past&numberposts=-1' ) as $publish ) {
        $post->menu_item_parent = $parent_item_id;
        $post->post_type="nav_menu_item";
        $post->object="customized";
        $post->sort="customized";
        $post->menu_order = ++$menu_order;
        $post->title = $post->post_title;
        $post->url = get_permalink( $post->ID );
        array_push($child_items, $publish); // If i remark out this line, the customiser returns as regular. 
      }

  }
  return array_merge( $objects, $child_items );
}

After I remark out the road containing array_push, the customiser will return as regular. Makes me consider it’s one thing to do with the child_items.

Anybody have any concepts how you’ll repair this?

Thanks
