remove_submenu_page() │ WP 3.1.0

remove_submenu_page( 'options-general.php', 'options-permalink.php' );

Так как функция добавлена в версии 3.1, возможно, что нам понадобится совместимость с более ранними версиями ВП, организовать её можно таким образом, добавив код в function.php:

add_action( 'admin_menu', 'my_remove_menu_pages' );

function my_remove_menu_pages() {

	// WP 3.1+
	if ( function_exists('remove_menu_page') ) {
		remove_submenu_page( 'options-general.php', 'options-discussion.php' );
	}
	// WP ниже 3.1
	else {
		unset( $GLOBALS['submenu']['options-general.php'][25] );
	}
}

В данном примере мы удалили подпункт "Обсуждение" в меню настроек:

Элементы из этого массива нужно указывать в этой функции:

$menu_slug - ключ массива.
$submenu_slug - третий элемент массива.
