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.

use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
class DemoController
{
/**
* @Route("/hello/{username}", name="_hello", requirements={"username"=".+"})
*/
public function helloAction($username)
{
// ...
}
}

_hello:
path: /hello/{username}
defaults: { _controller: AppBundle:Demo:hello }
requirements:
username: .+

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.
