I'm trying to implement the register part of a project in Symfony with the Sonata Bundle but i get the exception "Cannot redirect to an empty URL". The error is generated in the controller file RegistrationFOSUser1Controller in the registerAction.
public function registerAction()
{
$user = $this->container->get('security.context')->getToken()->getUser();
if ($user instanceof UserInterface) {
$this->container->get('session')->getFlashBag()->set('sonata_user_error', 'sonata_user_already_authenticated');
$url = $this->container->get('router')->generate('booster_bici_homepage');
return new RedirectResponse($url);
}
$form = $this->container->get('sonata.user.registration.form');
$formHandler = $this->container->get('sonata.user.registration.form.handler');
$confirmationEnabled = $this->container->getParameter('fos_user.registration.confirmation.enabled');
$process = $formHandler->process($confirmationEnabled);
if ($process) {
$user = $form->getData();
$authUser = false;
if ($confirmationEnabled) {
$this->container->get('session')->set('fos_user_send_confirmation_email/email', $user->getEmail());
$url = $this->container->get('router')->generate('fos_user_registration_check_email');
} else {
$authUser = true;
$route = $this->container->get('session')->get('sonata_basket_delivery_redirect');
if (null !== $route) {
$this->container->get('session')->remove('sonata_basket_delivery_redirect');
$url = $this->container->get('router')->generate($route);
} else {
$url = $this->container->get('session')->get('sonata_user_redirect_url');//IT SEEMS THAT HERE IS RETURNED NULL
}
}
$this->setFlash('fos_user_success', 'registration.flash.user_created');
$response = new RedirectResponse($url);// THIS IS THE LINE OF THE ERROR
if ($authUser) {
$this->authenticateUser($user, $response);
}
return $response;
}
$this->container->get('session')->set('sonata_user_redirect_url', $this->container->get('request')->headers->get('referer'));
return $this->container->get('templating')->renderResponse('FOSUserBundle:Registration:register.html.'.$this->getEngine(), array(
'form' => $form->createView(),
));
}
The part where the error is generated is :
if ($process) {
$user = $form->getData();
$authUser = false;
if ($confirmationEnabled) {
$this->container->get('session')->set('fos_user_send_confirmation_email/email', $user->getEmail());
$url = $this->container->get('router')->generate('fos_user_registration_check_email');
} else {
$authUser = true;
$route = $this->container->get('session')->get('sonata_basket_delivery_redirect');
if (null !== $route) {
$this->container->get('session')->remove('sonata_basket_delivery_redirect');
$url = $this->container->get('router')->generate($route);
} else {
$url = $this->container->get('session')->get('sonata_user_redirect_url'); //IT SEEMS THAT HERE IS RETURNED NULL
}
}
$this->setFlash('fos_user_success', 'registration.flash.user_created');
$response = new RedirectResponse($url);// THIS IS THE LINE OF THE ERROR
I can see that the problem is that $url is empty. I have traced the problem to the line:
$url = $this->container->get('session')->get('sonata_user_redirect_url');
It seems that $this->container->get('session')->get('sonata_user_redirect_url') returns null but i don't know what to do in order to avoid that or what i'm doing wrong.
Any ideas?
