Symfony2 Language for TLD

Question

I'm new in Symfony2 and I'm looking for choose the language with the TLD of my hostname. (in a proper way)

I already find some way to change the language with a form: http://symfony.com/blog/play-with-the-user-language

But I need to be able to select the language when a new user connect with:

• www.hostname.fr => fr
• www.hostname.it => it
• www.hostname.co.uk => en

For now I add a service listener that trigger for each request:

services:
    kernel.listener.domain_langue_listener:
        class: acme\DemoBundle\Listener\DomainLangueListener
        tags:
            - { name: kernel.event_listener, event: kernel.request, method: onDomainParse }

With the class:

namespace acme\DemoBundle\Listener;
class DomainLangueListener
{
    public function onDomainParse(Event $event)
    {
        $request = $event->getRequest();
        $session = $request->getSession();

        preg_match('/[^.]+$/', $request->getHost(), $match);
        $session->setLocale($match[0]);
    }
}

This Listener works but I would like to use some Parameters to define which TLD match with which Language, But in the Listener I cannot access to the container like that:

$this->container->getParameter('tld_allowed');

I would like to know if there is another way to access to Parameters in a Listener Or an other way to select a language with the hostname

Thanks for your answers.

You're almost there. The only thing you have to do now is inject the parameters into your listener, using "arguments" (arguments for the constructor). %foobar% refers to the "foobar" parameter, @foobar refers to the "foobar" service.

parameters:
    tld_allowed: en,fr,de

services:
    kernel.listener.domain_langue_listener:
        class: acme\DemoBundle\Listener\DomainLangueListener
        arguments:
            - %tld_allowed%
        tags:
            - { name: kernel.event_listener, event: kernel.request, method: onDomainParse }

And the listener:

namespace acme\DemoBundle\Listener;
class DomainLangueListener
{
    public function __construct($tldAllowed)
    {
        $this->tldAllowed = $tldAllowed;
    }

    ...
}
