/* wp-admin-menu-classes.php
Classes to encapsulate access to admin menu global arrays $menu and $submenu
See:
-- http://core.trac.wordpress.org/ticket/12718
-- http://core.trac.wordpress.org/ticket/11517
version: 1.05 - Renamed "delete_*" functions to "remove_*" (Oct 6 2010)
version: 1.04 - Another significant update. Attempted to make PHP 4.x compatible (Sept 30 2010)
Added hookname property to both section and item
Renamed property with list of items to be "items" instead of "submenus"
version: 1.03 - Major Rewrite over v1.02. Designed for hopeful inclusion within WordPress v3.1 (Sept 29 2010)
version: 1.02 - Added remove_admin_menu_item(), changed "find-by"=="title" to search on RegEx (Sept 27 2010)
Designed for hopeful inclusion within WordPress v3.1
Examples of use:
// This example creates one menu in place of Dashboard called "My Menu", adds a few things, and removes all else.
// This example assumes this might only be done for end users, not administrators
$dashboard = rename_admin_menu_section('Dashboard','My Menu');
// // Alternate approach
// remove_admin_menu_item('index.php'); // Dashboard
// $dashboard = add_admin_menu_section(array(
// 'title' => 'My Menu',
// 'slug' => 'index.php',
// ));
remove_admin_menu_item($dashboard,'index.php'); // Dashboard
remove_admin_menu_item($dashboard,'update-core.php'); // Updates
$movies = "edit.php?post_type=movie";
copy_admin_menu_item($dashboard,$movies);
$movie_genre = 'edit-tags.php?taxonomy=movie-genre&post_type=movie';
copy_admin_menu_item($dashboard,$movies,$movie_genre);
rename_admin_menu_item($dashboard,$movie_genre,'Movie Genre');
remove_admin_menu_item($movies);
remove_admin_menu_item($movies,$movie_genre);
remove_admin_menu_item($movies,'post-new.php?post_type=movie');
remove_admin_menu_section($movies);
$actors = "edit.php?post_type=actor";
copy_admin_menu_item($dashboard,$actors);
remove_admin_menu_item($actors);
remove_admin_menu_item($actors,'post-new.php?post_type=actor');
//remove_admin_menu_section($actors);
rename_admin_menu_item($dashboard,'Pages','Other Pages');
remove_admin_menu_section('edit.php'); // Posts
remove_admin_menu_section('upload.php'); // Media
remove_admin_menu_section('link-manager.php'); // Links
remove_admin_menu_section('edit-comments.php'); // Comments
remove_admin_menu_section('edit.php?post_type=page'); // Pages
remove_admin_menu_section('plugins.php'); // Plugins
remove_admin_menu_section('themes.php'); // Appearance
remove_admin_menu_section('users.php'); // Users
remove_admin_menu_section('tools.php'); // Tools
remove_admin_menu_section('options-general.php'); // Settings
