Php – Email confirmation on FOSUserBundle Profile Edit

fosuserbundlephpsymfony

I would like to activate the email confirmation on FOSUserBundle /profile/edit

In /profile/edit you are already logged in and you can edit the username or the email address entering the current password.
Now I would like to send a confirmation email if the user edit the email address 🙂

In the FOSUserBundle Configuration Reference I haven't found a setting to do this…
https://github.com/FriendsOfSymfony/FOSUserBundle/blob/master/Resources/doc/configuration_reference.md

These are my current settings:

fos_user:
  db_driver: orm
  firewall_name: main
  user_class: Acme\CoreBundle\Entity\User
  registration:
    confirmation: { enabled: true }
  from_email:
    address: noreply@%domain%
    sender_name: %site_name% Staff
  resetting:
    token_ttl: %reset_password_ttl%

Someone can help me?

Best Solution

Using new FOSUserBundle's events (FOS 2.0 feature), you can create a ChangeProfileListener that handle email changes.

The idea : use the same logic as a registration process : disable our user, send him a token (and logging-him out for our case).

There is two things to do :

  • create an event suscriber
  • overwrite the mail.txt.twig to replace the "registration" message by a neutral "email confirmation" message.

Here is my listener, don't forget to replace namespace.

EventListener/ChangeProfileListener.php:

<?php

// src/Fuz/HomeBundle/EventListener/ChangeProfileListener.php

namespace Fuz\HomeBundle\EventListener;

use FOS\UserBundle\FOSUserEvents;
use FOS\UserBundle\Event\GetResponseUserEvent;
use FOS\UserBundle\Event\FormEvent;
use FOS\UserBundle\Mailer\MailerInterface;
use FOS\UserBundle\Util\TokenGeneratorInterface;
use Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorageInterface;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use Symfony\Component\HttpFoundation\RedirectResponse;
use Symfony\Component\HttpFoundation\Session\SessionInterface;
use Symfony\Component\Routing\Generator\UrlGeneratorInterface;

class ChangeProfileListener implements EventSubscriberInterface
{

    private $mailer;
    private $tokenGenerator;
    private $router;
    private $session;
    private $tokenStorage;

    public function __construct(MailerInterface $mailer, TokenGeneratorInterface $tokenGenerator,
       UrlGeneratorInterface $router, SessionInterface $session, TokenStorageInterface $tokenStorage)
    {
        $this->mailer = $mailer;
        $this->tokenGenerator = $tokenGenerator;
        $this->router = $router;
        $this->session = $session;
        $this->tokenStorage = $tokenStorage;
    }

    public static function getSubscribedEvents()
    {
        return array(
                FOSUserEvents::PROFILE_EDIT_INITIALIZE => 'onProfileEditInitialize',
                FOSUserEvents::PROFILE_EDIT_SUCCESS => 'onProfileEditSuccess',
        );
    }

    public function onProfileEditInitialize(GetResponseUserEvent $event)
    {
        // required, because when Success's event is called, session already contains new email
        $this->email = $event->getUser()->getEmail();
    }

    public function onProfileEditSuccess(FormEvent $event)
    {
        $user = $event->getForm()->getData();
        if ($user->getEmail() !== $this->email)
        {
            // disable user
            $user->setEnabled(false);

            // send confirmation token to new email
            $user->setConfirmationToken($this->tokenGenerator->generateToken());
            $this->mailer->sendConfirmationEmailMessage($user);

            // force user to log-out
            $this->tokenStorage->setToken();

            // redirect user to check email page
            $this->session->set('fos_user_send_confirmation_email/email', $user->getEmail());
            $url = $this->router->generate('fos_user_registration_check_email');
            $event->setResponse(new RedirectResponse($url));
        }
    }

}

services.yml :

parameters:
    fuz_home.email_change.listener.class: Fuz\HomeBundle\EventListener\ChangeProfileListener

services:
      fuz_home.email_change.listener:
          class: %fuz_home.email_change.listener.class%
          arguments: ['@fos_user.mailer', '@fos_user.util.token_generator', '@router', '@session', '@security.token_storage']
          tags:
            - { name: kernel.event_subscriber }

About overwritting email template, that's just creating app/Resources/FOSUserBundle/views/Registration/email.txt.twig and put, for example :

{% block subject %}
Email Confirmation
{% endblock %}

{% block body_text %}

Welcome to example.com, {{ user.username }}!                                                

To confirm your email, please follow this link:                                                                    
{{ confirmationUrl }}

You will be able to log-in using the username or email you given:                                        

Username : {{ user.username }}                                                                                                         
Email    : {{ user.email }}                                                                                                 

If you received this e-mail in error just ignore this message. No further actions are required from you.                  



                                                     *****                                                           

                                                 See you soon!
