    Hi,

    i'm using include/exclude addon, where i have a custom param (function) to show this metabox only for pages, that have some top parent page ID - it's ok. Problem is, when i save the post (the content from custom field is empty) - so it seems, that my function for test top parent page id is executed early before WP knows ID for current saving post.

    How can i solve this?

    Can I see your function for test top parent page ID? Can you post your code?

    This function shows me a metabox for pages, that have top parent page id "429".

    function parent_page_id_check(){
	if( is_admin() && isset($_GET['post']) ){
		$id = $_GET['post'];
		$parents = get_post_ancestors($id);
		$id = ($parents) ? $parents[count($parents)-1] : $id;
		return ($id == 429) ? true : false;
	}
}

    Why don't you use parent rule? It's supported by default 😉

    Because i have not only a single subpage (page - subpage - subsubpage ..)

    Hi again,

    I found the problem for your situation. Your check doesn't run when post is updated, because there's no $GET['post']. In that case, you need to get post ID via $_POST. Here is the code:

    function prefix_parent_page_id_check() {
	$parents = get_post_ancestors( prefix_get_post_id() );
	return $parents && 901 == array_pop( $parents );
}

function prefix_get_post_id() {
	if ( isset( $_GET['post'] ) ) {
		return intval( $_GET['post'] );
	}
	if ( isset( $_POST['post_ID'] ) ) {
		return intval( $_POST['post_ID'] );
	}

	return false;
}
