wordpress 移除 后台某些选项卡 及 后台adminbar的 dashboard选项

有时候为客户做后台不需要让非管理员用户看到 dashboard选项 及某些后台选项卡 如tools theme等

所以需要隐藏掉 一些

1.隐藏dashboard

function remove_the_dashboard () {
	if (current_user_can('level_10')) {
		return;
	} else {

		global $menu, $submenu, $user_ID;
		$the_user = new WP_User($user_ID);
		reset($menu); $page = key($menu);
		while ((__('Dashboard') != $menu[$page][0]) && next($menu))
			$page = key($menu);
		if (__('Dashboard') == $menu[$page][0]) unset($menu[$page]);
		reset($menu); $page = key($menu);
		while (!$the_user->has_cap($menu[$page][1]) && next($menu))
			$page = key($menu);
		if (preg_match('#wp-admin/?(index.php)?$#',$_SERVER['REQUEST_URI']) && ('index.php' != $menu[$page][2]))
			wp_redirect(get_option('siteurl') . '/wp-admin/profile.php');
	}
}
add_action('admin_menu', 'remove_the_dashboard');

 2.隐藏 tools theme等

//Hide non-userd admin menu bar
function yg_remove_menu_page() {
	remove_menu_page('tools.php');
	remove_menu_page('themes.php');
}
add_action( 'admin_menu', 'yg_remove_menu_page' );

 3.隐藏后台的wordpress信息

//Hide the wordpress info
function change_footer_admin () {
	return 'Powerd by Gruden';
}
add_filter('admin_footer_text', 'change_footer_admin', 9999);
function change_footer_version() {
	return ' ';
}
add_filter( 'update_footer', 'change_footer_version', 9999);
