20878	Invalid get_admin_page_parent(), after use of remove_submenu_page()	hinok		"I create my plugin pages with functions:

{{{
add_menu_page()
add_submenu_page()
}}}

It works.

I want hide some of my subpages, so I used:
{{{
remove_submenu_page().
}}}

My pages was removed from wordpress menu admin, but I '''can not''' view them by direct url.
I get only error: 

{{{
You do not have sufficient permissions to access this page.
}}}

I found that, problem is with ''get_admin_page_parent()'', because my hookname was different. (when I used remove_submenu_page(), and not), for example:[[BR]]

Without use of remove_submenu_page:[[BR]]
''prefixgeneratedfromtitlepage_my-slug-page''[[BR]]


With use of remove_submenu_page:[[BR]]
''admin_page_my-slug-page''[[BR]]

I found function ''user_can_access_admin_page()'' in wp-admin/includes/menu.php, and then look in wp-admin/includes/plugin.php, I found this:

{{{
		if ( !isset($_registered_pages[$hookname]) ) // here is problem with wrong generated $hookname
			return false; 
}}}

'''I get return false, because $hookname was wrong generated.'''
Why hookname was wrong generated? Because I dont get my $parent.

So I found ''get_plugin_page_hookname()'' and ''get_admin_page_parent()'' in wp-admin/includes/plugins.php.

Weird is that, global variables like $_registered_pages and $_parent_pages are OK.
So I used this piece of code  to repair my problem.

In 1403 line of wp-admin/icludes/plugin.php, I added:

{{{
	global $_parent_pages;
	// global $plugin_page; // globalized above
	foreach ($_parent_pages as $key => $value) {
		if ( $key == $plugin_page ) {
			return $value;
		}
	}
}}}

And now is ok, but my wordpress menu doesnt open, when I view my hidden page.

Why in get_admin_page_parent(), wordpress doesn`t look for $parent in $_parent_pages?"	defect (bug)	closed	normal		Administration	3.3.2	major	duplicate		mail@…
