Call an route on each page - php

Question

I have a question. I added a new service PopupListener.php:
use Symfony\Bundle\FrameworkBundle\Routing\Router;
use Symfony\Component\DependencyInjection\ContainerInterface;
class PopupListener
{
protected $router;
public function __construct(Router $router)
{
$this->router = $router;
}
public function onKernelRequest()
{
$this->router->generate('app_popup_trigger');
}
}
services.yml :
popup_listener:
class: App\DesktopBundle\Listeners\PopupListener
arguments: ["#router"]
tags:
- { name: kernel.event_listener, event: kernel.request, method: onKernelRequest }
routing.yml :
app_popup_trigger:
path: /popup/trigger
defaults: { _controller: AppDesktopBundle:Popup:triggerPopup }
The triggerPopupAction :
class PopupController extends Controller{
public function triggerPopupAction(){
return $this->render('AppDesktopBundle:Popup:index.html.twig', array());
}
}
I want that at each route call the new route added : app_popup_trigger. I made somethink like that but not work. The route is not called. Can you help me please ?

Answer 1

Basically use FOSJsRoutingBundle and trigger your route with javascript. That will be easier than listeners for a popup.

Answer 2

To call a specific route at the start of every request, you just need to extend your code in your PopupListener:
use Symfony\Bundle\FrameworkBundle\Routing\Router;
use Symfony\Component\DependencyInjection\ContainerInterface;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpKernel\Event\GetResponseEvent;
use Symfony\Component\HttpKernel\HttpKernelInterface;
class PopupListener
{
protected $router;
protected $httpKernel;
public function __construct(Router $router, HttpKernelInterface $httpKernel)
{
$this->router = $router;
$this->httpKernel = $httpKernel;
}
public function onKernelRequest(GetResponseEvent $event)
{
if (HttpKernelInterface::MASTER_REQUEST !== $event->getRequestType()) {
return;
}
$subRequest = Request::create($this->router->generate('app_popup_trigger'));
$response = $this->httpKernel->handle($subRequest, HttpKernelInterface::SUB_REQUEST);
// do something with the $response here
}
}
Symfony will start a new request-response cycle just for this sub-request and will return the $response of this cycle. Then you have to decide what you are doing with that reponse.
And then add the additional service to your service configuration:
popup_listener:
class: App\DesktopBundle\Listeners\PopupListener
arguments: ["#router", "#http_kernel"]
tags:
- { name: kernel.event_listener, event: kernel.request, method: onKernelRequest }
You can get more information about symfony sub-requests here: The HttpKernel Component - Sub Request. I linked the documentation for Symfony 2.3. But keep in mind Symfony 2.3 is not maintained anymore and you should consider upgrading to 3.x.
