Install Locale in Symfony with the GET param parameter

Question

I created a controller that sets the security token manually, according to the encrypted GET parameters. I use this to create a remote login URL that will login when the user follows this link.

Now I would like to add a locale setting. When the Lang parameter is provided, it must set the locale. I added this to the controller:

$lang = strtolower($lang); $this->getRequest()->getSession()->set('_locale', $lang); $this->getRequest()->setLocale($lang); $this->container->get('translator')->setLocale($lang); 

The _locale variable is set to customize according to the development panel. The language file is not loaded, but returns to the default language.

I read about creating a Listener to achieve this, but it seems to me that this is useful when you want to specify the language in the url. I do not want to add this to my routing, I just want to set the locale when creating the session.

UPDATE:

I went on to simulate an old beheavor solution , as provided by Symfony. However, setting the Locale query does not work. When I repeat this in my Twig template, the values ​​are not equal: req lang: {{ app.request.locale }} session: {{ app.session.get('_locale') }} . The LocaleListener, as shown below, works, although I checked this by inserting die() and also setting the language standard of the Translator service, it seems to work.

So, having installed the translator language, I got this job. However, I do not understand why. Should the translation service use the query language? Why do I need to install this manually?

Is the language object in the Request object for anything other than a translation?

 <?php namespace Mb\MyBundle\Listener; use Symfony\Component\HttpKernel\Event\GetResponseEvent; use Symfony\Component\HttpKernel\KernelEvents; use Symfony\Component\EventDispatcher\EventSubscriberInterface; class LocaleListener implements EventSubscriberInterface { private $translator; public function __construct($translator) { $this->translator = $translator; } public function onKernelRequest(GetResponseEvent $event) { $request = $event->getRequest(); if (!$request->hasPreviousSession()) { return; } if (strlen( $request->getSession()->get('_locale') )) { $request->setLocale($request->getSession()->get('_locale')); $this->translator->setLocale($request->getSession()->get('_locale')); } } static public function getSubscribedEvents() { return array( // must be registered before the default Locale listener KernelEvents::REQUEST => array(array('onKernelRequest', 17)), ); } } 

And in my services.yml I have:

 mb.locale.listener: class: Mb\MyBundle\Listener\LocaleListener arguments: [@translator] tags:An - { name: kernel.event_subscriber } 

If someone can explain to me what is happening here, I would be very happy :-)

Answer 1

I had the same problem, and I wonder if this depends on the order of the listeners:

php bin/console debug:event-dispatcher shows

 "kernel.request" event ---------------------- Order Callable Priority ------------------------------------------------ ---------- #1 Symfony\Component\HttpKernel\EventListener\DebugHandlersListener::configure() 2048 #2 Symfony\Component\HttpKernel\EventListener\DumpListener::configure() 1024 #3 Symfony\Component\HttpKernel\EventListener\ValidateRequestListener::onKernelRequest() 256 #4 Symfony\Bundle\FrameworkBundle\EventListener\SessionListener::onKernelRequest() 128 #5 Symfony\Component\HttpKernel\EventListener\FragmentListener::onKernelRequest() 48 #6 Symfony\Component\HttpKernel\EventListener\RouterListener::onKernelRequest() 32 #7 Symfony\Component\HttpKernel\EventListener\LocaleListener::onKernelRequest() 16 #8 Symfony\Component\HttpKernel\EventListener\TranslatorListener::onKernelRequest() 10 #9 Symfony\Component\Security\Http\Firewall::onKernelRequest() 8 #10 AppBundle\Service\LocaleListener::onKernelRequest() 0 #11 Symfony\Bundle\AsseticBundle\EventListener\RequestListener::onKernelRequest() 0 

and # 10 belongs to me and should after # 7 LocaleListener and before # 8 TranslatorListener, so I have to remind the translator in my service.
