Linking a user to another entity on create in Symfony2

Question

I am using the FOS_user bundle and when I create a user I want to link it to another Entity which is Company. I have tried to create a Listener using the following code:

public static function getSubscribedEvents()
{
    return array(
        FOSUserEvents::REGISTRATION_SUCCESS => 'onRegistrationSuccess',
    );
}

public function onRegistrationSuccess(FormEvent $event) {

}

This is working good and I have access to $event in the function. Now, I want to access the name of the company that the user added in the form. Also, I want to create a company and bind it to the new user, so something like this:

$company = new Entity\Company();
$company->setTitle($theInputFromTheForm);
$user->addCompany($company);

I don't know how to access the data of the form and save the company in the user. Is using a listener the proper way to do it?

Answer 1

The event FOSUserEvents::REGISTRATION_SUCCESS receive a FormEvent object. You can get the registration form in your listener using $event->getForm()

So in you case;

public function onRegistrationSuccess(FormEvent $event) {
    $registrationForm = $event->getForm();
    $registrationFormData = registrationForm->getData();
}

Answer 2

I ended up creating a form type CompanyType that adds the title of my company. In my RegistrationFormType of my UserBundle I added a collection to this form type. I created a listener on FOSUserEvents::REGISTRATION_INITIALIZE to add an empty company.

public function onRegistrationInitialize(UserEvent $event) {
    $user = $event->getUser();
    $user->addCompany($company);
}
