How to configure symfony2/3 to handle different domains serving different views? - symfony

Question

Is it possible to configure symfony2/3 to handle more than 1 domain with different views?
For example I have site1.com and site2.com, I would create a site1 and site2 folders inside app/Resources/views and serve a different set of templates depending on the domain.
Models and controllers should be in common so site1.com/mypage and site2.com/mypage should serve the same content with different layout.
Any suggestion or best practice related to it is welcome.
Thanks

Check for the host in your controller :
namespace Acme\FooBundle\Controller;
use Symfony\Component\HttpFoundation\Request;
class DemoController
{
public function showAction(Request $request)
{
switch($request->getHost())
{
case 'site1.com':
return $this->render('site1/show.html.twig');
break;
case 'site2.com':
return $this->render('site2/show.html.twig');
break;
default:
return $this->render('default/show.html.twig');
}
}
}
EDIT : Something more generic
Create a onKernelRequest listener :
namespace AppBundle\EventListener;
use Symfony\Component\HttpKernel\Event\GetResponseEvent;
use Symfony\Component\HttpKernel\Exception\NotFoundHttpException;
class DomainRequestListener
{
public function onKernelRequest(GetResponseEvent $event)
{
$request = $event->getRequest();
$host = explode('.',$request->getHost());
$request->request->attributes->set('_domain',$host[0]);
}
}
Add this listener in services.yml :
app.listener.domain_request:
class: AppBundle\EventListener\DomainRequestListener
tags:
- { name: kernel.event_listener, event: kernel.request, method: onKernelRequest}
Then you can use the '_domain' routing parameter in all your controllers :
return $this->render($request->attributes->get('_domain').'/show.html.twig');

Not tested, but I expect the following should work. You'll want to register a kernel request listener that uses the Twig loader service (responsible for locating the templates) and registers a path based on the request's hostname.
Create a request listener:
<?php
use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use Symfony\Component\HttpKernel\Event\GetResponseEvent;
use Symfony\Component\HttpKernel\KernelEvents;
class RegisterTwigPathSubscriber implements EventSubscriberInterface
{
private $loader;
public function __construct(\Twig_Loader_Filesystem $loader)
{
$this->loader = $loader;
}
public static function getSubscribedEvents()
{
return [
KernelEvents::REQUEST => 'registerTwigPath'
];
}
public function registerTwigPath(GetResponseEvent $event)
{
$host = $event->getRequest()->getHost();
$path = '...'; // determine path based on hostname
$this->loader->addPath($path, 'Theme'); // the second argument is a namespace for templates located under this folder and can be chosen
}
}
Register the event listener:
services:
register_twig_path_listener:
class: RegisterTwigPathSubscriber
arguments: ["#twig.loader"]
tags: [{ name: kernel.event_subscriber }]
Now to reference the template:
return $this->render('#Theme/path/to/actual/template.html.twig');
