Set the email manually with FOSUserBundle - symfony

Question

I am using Symfony 2 + FOSUserBundle to manage my users.
The problem is that I would like to build the email address "manually" from the username, and so, do not require any field for the email.
I will create the email from the username because one requirement to sign up is to have an email from my university which follows a strict format (username#schoolname.fr).
I managed to override the RegistrationFormType to avoid the email field from being added to my sign up page but I still have the error "Please enter an email" when I submit the form.
How can I prevent the validation of the email address and how could I "build" it from the username?
Thanks!
(Sorry for the English, I know it's not perfect...)

Answer 1

There is a simple way around it. It is even mentioned in the official FOSUserBundle documentation. You just need to override the controller.
Create your own Bundle and extend the FOSUserBundle:
class CustomUserBundle extends Bundle
{
public function getParent()
{
return 'FOSUserBundle';
}
}
And then override the RegistrationController:
class RegistrationController extends BaseController
{
public function registerAction(Request $request)
{
// here you can implement your own logic. something like this:
$user = new User();
$form = $this->container->get('form.factory')->create(new RegistrationType(), $user);
if ($request->getMethod() == 'POST') {
$form->bind($request);
if ($form->isValid()) {
$user->setEmail($user->getUsername() . '#' . $user->getSchoolname() . '.fr');
// and what not. Also don't forget to either activate the user or send an activation email
}
}
}
}

You should write event listener for fos_user.registration.initialize. From code docs:
/**
* The REGISTRATION_INITIALIZE event occurs when the registration process is initialized.
*
* This event allows you to modify the default values of the user before binding the form.
* The event listener method receives a FOS\UserBundle\Event\UserEvent instance.
*/
const REGISTRATION_INITIALIZE = 'fos_user.registration.initialize';
More info about event dispatcher: http://symfony.com/doc/current/components/event_dispatcher/introduction.html
And example event listener: http://symfony.com/doc/current/cookbook/service_container/event_listener.html
UPDATE - how to code?
In your config.yml (or services.yml or other extension like xml, php) define service like this:
demo_bundle.listener.user_registration:
class: Acme\DemoBundle\EventListener\Registration
tags:
- { name: kernel.event_listener, event: fos_user.registration.initialize, method: overrideUserEmail }
Next, define listener class:
namespace Acme\DemoBundle\EventListener;
class Registration
{
protected function overrideUserEmail(UserEvent $args)
{
$request = $args->getRequest();
$formFields = $request->get('fos_user_registration_form');
// here you can define specific email, ex:
$email = $formFields['username'] . '#sth.com';
$formFields['email'] = $email;
$request->request->set('fos_user_registration_form', $formFields);
}
}
Notice: Of course you can validate this email via injecting #validator to the listener.
Now you should hide email field in registration form. YOu can do that by overriden register_content.html.twig or (in my oppinion better way) override FOS RegistrationFormType like this:
namespace Acme\DemoBundle\Form\Type;
use FOS\UserBundle\Form\Type\RegistrationFormType as BaseType;
use Symfony\Component\Form\FormBuilderInterface;
class RegistrationFormType extends BaseType
{
// some code like __construct(), getName() etc.
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
// some code for your form builder
->add('email', 'hidden', array('label' => 'form.email', 'translation_domain' => 'FOSUserBundle'))
;
}
}
Now your application is ready for setting email manually.
