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%"}).

Current route: {{ app.request.get('_route') }}

->

Current route: snippet_show
