I am new to Symfony and I pretty much now understand the basics and now I am diving into Events and Events Listeners.
I understand that when a user registers via FOSUserBundle there are three Events that get dispatched inside registerAction()
- REGISTRATION_INITIALIZE
- REGISTRATION_SUCCESS
- REGISTRATION_COMPLETED
This is the registerAction
code
public function registerAction(Request $request)
{
/** @var $formFactory \FOS\UserBundle\Form\Factory\FactoryInterface */
$formFactory = $this->get('fos_user.registration.form.factory');
/** @var $userManager \FOS\UserBundle\Model\UserManagerInterface */
$userManager = $this->get('fos_user.user_manager');
/** @var $dispatcher \Symfony\Component\EventDispatcher\EventDispatcherInterface */
$dispatcher = $this->get('event_dispatcher');
$user = $userManager->createUser();
$user->setEnabled(true);
$event = new GetResponseUserEvent($user, $request);
$dispatcher->dispatch(FOSUserEvents::REGISTRATION_INITIALIZE, $event);
if (null !== $event->getResponse()) {
return $event->getResponse();
}
$form = $formFactory->createForm();
$form->setData($user);
$form->handleRequest($request);
if ($form->isValid()) {
$event = new FormEvent($form, $request);
$dispatcher->dispatch(FOSUserEvents::REGISTRATION_SUCCESS, $event);
$userManager->updateUser($user);
if (null === $response = $event->getResponse()) {
$url = $this->generateUrl('fos_user_registration_confirmed');
$response = new RedirectResponse($url);
}
$dispatcher->dispatch(FOSUserEvents::REGISTRATION_COMPLETED, new FilterUserResponseEvent($user, $request, $response));
return $response;
}
return $this->render('FOSUserBundle:Registration:register.html.twig', array(
'form' => $form->createView(),
));
}
Now inside the config.yml
we can setup the configuration so the user is required to confirm their email address before their account gets activated and this is where I get lost
fos_user:
registration:
confirmation:
enabled: true
I am looking at EmailConfirmationListener which listens to the REGISTRATION_SUCCESS
and inside this code I am finding nothing that tells me how it is reading the confirmation
in config.yml
I will really appreciate if someone can explain to me how this listener is triggered based on confirmation
enabled
status.
