Symfony 2：FOSUserBundle：使用FOSUserEvents进行重定向

Question

I have implemented FOSUserBundle in my Symfony 2 project to manage my members. Each time a form is successfully filled (registration, changing password...) I redirect the user to my homepage. To do this I use the SUCCESS events provided by the bundle (see the documentation : Hooking into the controllers ).

It works fine for CHANGE_PASSWORD_SUCCESS and PROFILE_EDIT_SUCCESS events but it doesn't work for the FOSUserEvents::REGISTRATION_SUCCESS event. I am not redirected after user registration (the default bundle 'show profile' page is displayed). EDIT : (the default bundle 'check email' page is displayed as the option registration confirmation by email is enabled).

I have implemented this code .

Can someone help me to understand why ? My code here below:

Thank you for your help.

The listener :

<?php

// src/FBN/UserBundle/EventListener/FormSuccessListener.php

namespace FBN\UserBundle\EventListener;

use FOS\UserBundle\FOSUserEvents;
use FOS\UserBundle\Event\FormEvent;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use Symfony\Component\HttpFoundation\RedirectResponse;
use Symfony\Component\Routing\Generator\UrlGeneratorInterface;

/**
 * Listener responsible to change the redirection when a form is successfully filled
 */
class FormSuccessListener implements EventSubscriberInterface
{
    private $router;

    public function __construct(UrlGeneratorInterface $router)
    {
        $this->router = $router;
    }

    /**
     * {@inheritDoc}
     */
    public static function getSubscribedEvents()
    {
        return array(
            FOSUserEvents::REGISTRATION_SUCCESS => 'onFormSuccess',    // Not working
            FOSUserEvents::CHANGE_PASSWORD_SUCCESS => 'onFormSuccess', // Working
            FOSUserEvents::PROFILE_EDIT_SUCCESS => 'onFormSuccess',    // Working                   
        );
    }

    public function onFormSuccess(FormEvent $event)
    {
        $url = $this->router->generate('fbn_guide_homepage');

        $event->setResponse(new RedirectResponse($url));
    }
}

The service :

services:
    fbn_user.formsuccess_listener:
        class: FBN\UserBundle\EventListener\FormSuccessListener
        arguments: [@router]
        tags:
            - { name: kernel.event_subscriber }

Answer 1

I think you are hooking the wrong event. According to what I've found in the RegistrationController of FosUserBundle , you have to subscribe to FOSUserEvents::REGISTRATION_COMPLETED event.

Answer 2

I confirm the solution proposed by Qoop in the 5th comment of the main post.

As the registration confirmation by email is enabled, the email confirmation listener is used. This listener sets a response on FOSUserEvents::REGISTRATION_SUCCESS after my own listener. So I had to change the priority of my listener in order to set the response :

So here is the modified listener :

// src/FBN/UserBundle/EventListener/FormSuccessListener.php

namespace FBN\UserBundle\EventListener;

use FOS\UserBundle\FOSUserEvents;
use FOS\UserBundle\Event\FormEvent;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use Symfony\Component\HttpFoundation\RedirectResponse;
use Symfony\Component\Routing\Generator\UrlGeneratorInterface;

/**
 * Listener responsible to change the redirection when a form is successfully filled
 */
class FormSuccessListener implements EventSubscriberInterface
{
    private $router;

    public function __construct(UrlGeneratorInterface $router)
    {
        $this->router = $router;
    }

    /**
     * {@inheritDoc}
     */
    public static function getSubscribedEvents()
    {
        return array(
            FOSUserEvents::REGISTRATION_SUCCESS => array('onFormSuccess',-10),
            FOSUserEvents::CHANGE_PASSWORD_SUCCESS => array('onFormSuccess',-10), 
            FOSUserEvents::PROFILE_EDIT_SUCCESS => array('onFormSuccess',-10),                        
        );
    }

    public function onFormSuccess(FormEvent $event)
    {
        $url = $this->router->generate('fbn_guide_homepage');

        $event->setResponse(new RedirectResponse($url));
    }
}

Actually i think the right answer is in the doc

http://symfony.com/doc/master/bundles/FOSUserBundle/controller_events.html

Registration success listener with enabled confirmation at the same time¶

When you have registration confirmation and you want to hook up to FOSUserEvents::REGISTRATION_SUCCESS event you will have to prioritize this listener to be called before FOS\\UserBundle\\EventListener\\EmailConfirmationListener::onRegistrationSuccess:

public static function getSubscribedEvents()
{
    return [
        FOSUserEvents::REGISTRATION_SUCCESS => [
            ['onRegistrationSuccess', -10],
        ],
    ];
}

If you don't do it, EmailConfirmationListener will be called earlier and you will be redirected to fos_user_registration_check_email route.
