Symfony 2和FOSUserBundle - 在注册期间从用户路径添加信息

Question

I have a Symfony 2 application making use of FOSUserBundle. The app will be used by members of a number of different organisations, and I'd like them to be able to go to an organisation-specific URL in order to register, for example http://www.myapp.com/[organisation_name]/register. How can I let FOSUserBundle handle the registration, but also add [organisation_name] to the User record it creates?

My research suggests I might need to hook into a FOSUserBundle event (REGISTRATION_SUCCESS?), but I'm not sure about the exact mechanics of that or getting info from the URL.

FOSUserBundle Events

You can use GET attribute, like this:

http://www.myapp.com/register?org=acme

Event subscriber, in this case, will look like this:

namespace Acme\DemoBundle\Event;

use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use FOS\UserBundle\Event\FormEvent;

class EventSubscriber implements EventSubscriberInterface
{
    public static function getSubscribedEvents()
    {
        return array(
            'fos_user.registration.success'  => array('onRegistrationSuccess', 10),
        );
    }

    public function onRegistrationSuccess(FormEvent $event)
    {
        $user = $event->getUser();
        $org = $event->getRequest()->query->get('org');
        $user->setOrganisation($org);
    }
}

And don't forget to register your subscriber in services.yml:

acme_demo.event_subscriber:
    class: Acme\DemoBundle\Event\EventSubscriber
    tags:
        - { name: kernel.event_subscriber }
