你是对的，这里没有过滤器，在这种情况下，你必须破解全局$_wp_registered_nav_menus:

add_action(\'after_setup_theme\', \'custom_menu_location_label\');
function custom_menu_location_label() {
    global $_wp_registered_nav_menus;
    $find = __(\'Header Menu\'); $replace = __(\'Something Else\');
    foreach ($_wp_registered_nav_menus as $location => $description) {
        if ($find == $description) {
            $_wp_registered_nav_menus[$location] = $replace;
        }
    }
}
