Meta Box

I was misunderstanding. Just updated the plugin to 1.1.1. Please try it.

Thanks

Strange, the code works fine to me:

Your code looks fine. I just found the problem. It's just the MB Settings Page is loaded at init with priority 5, which is later than widgets_init (fires at init with priority 0). So, to solve this problem, simply replace widgets_init with init!

Hi, the code still requires the Meta Box plugin to use. It's the heart of all extensions. With the exported code, you can remove the MB Builder extension, but still need to keep Meta Box active!

Hi,

As long as you saved theme settings, the settings is stored in the options table and of course, you can use the helper function to get it anytime you want, even before init hook. That's why when you print the value of the function prefix_mega_menu_widget_classes, it always work.

I guess the problem is the way you register menu locations in your theme. It probably happens after widgets_init hook. FYI, widgets_init hook fires at init with priority 0. So, if you register your menu locations at init with priority 10, it will run *after* and doesn't work. Try to move the code to register menu locations to priority 0. (You still need to check to make sure it runs *before* widgets_init).

Thanks a lot for your solution. It's extremely helpful for other people.

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;
}
