How to Allow a “/” Character in a Route Parameter

Sometimes, you need to compose URLs with parameters that can contain a slash /. For example, take the classic /hello/{username} route. By default, /hello/Fabien will match this route but not /hello/Fabien/Kris. This is because Symfony uses this character as separator between route parts.

This guide covers how you can modify a route so that /hello/Fabien/Kris matches the /hello/{username} route, where {username} equals Fabien/Kris.

Configure the Route

By default, the Symfony Routing component requires that the parameters match the following regex path: [^/]+. This means that all characters are allowed except /.

You must explicitly allow / to be part of your parameter by specifying a more permissive regex path.

  • Annotations
    use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
    class DemoController
         * @Route("/hello/{name}", name="_hello", requirements={"name"=".+"})
        public function helloAction($name)
            // ...
  • YAML
        path:     /hello/{username}
        defaults: { _controller: AppBundle:Demo:hello }
            username: .+
  • XML
    <?xml version="1.0" encoding="UTF-8" ?>
    <routes xmlns=""
        <route id="_hello" path="/hello/{username}">
            <default key="_controller">AppBundle:Demo:hello</default>
            <requirement key="username">.+</requirement>
  • PHP
    use Symfony\Component\Routing\RouteCollection;
    use Symfony\Component\Routing\Route;
    $collection = new RouteCollection();
    $collection->add('_hello', new Route('/hello/{username}', array(
        '_controller' => 'AppBundle:Demo:hello',
    ), array(
        'username' => '.+',
    return $collection;

That’s it! Now, the {username} parameter can contain the / character.
