Get the Symfony route name in a Twig template

Published on 2020-01-09 • Modified on 2020-01-09

Sometimes, it's useful to know the current route name in a Twig template. For example in a layout where you don't "receive" the route name from the controller. It allows setting an "active" class on your menu links depending on the current context. I am using this trick on this website. As you can see, the "snippet" entry of the menu is highlighted. In this case, I test if the current route starts with snippet_ as all routes of this controller start with this string thanks to the route annotation which is set at the class level:

* @Route("/{_locale}/snippets", name="snippet_", requirements={"_locale"="%locales_requirements%"})

    <li>Current route (short version): <b>{{ app.request.get('_route') }}</b></li>
    <li>Current route: <b>{{ app.request.attributes.get('_route') }}</b></li>
