Correct, I think you should create your own Event Listener and event for
your sign up code. Here's something that should work:
<?php
class EmailSubscriber implements \Doctrine\Common\EventSubscriber
{
private $emailLib;
public function __construct($emailLib)
{
$this->emailLib = $emailLib;
}
/**
*
* @return array An array of method names to execute when their events
are
* dispatched
*/
public function getSubscribedEvents()
{
return array('userRegistered');
}
public function userRegistered(UserRegistrationEvent $event)
{
$this->emailLib->send([
'to' => $event->getUser()->getEmail(),
'from' => '[email protected]',
'subject' => 'Welcome to MySite.com',
'body' => 'Welcome'
]);
}
}
class UserRegistrationEvent
{
protected $user;
public function __construct(User $user)
{
$this->user = $user;
}
public function getUser()
{
return $this->user;
}
}
// This should be done in a ServiceProvider. Your signup code has
// to have access to this instance of EventManager.
$evm = new EventManager(); // Instance of Doctrine's Event Manager
$evm->addEventSubscriber(new EmailSubscriber());
// The following would be in your signup code:
$user = new User();
// other domain logic
$this->dm->persist($user);
$this->dm->flush($user);
$this->evm->dispatch('userRegistered', new UserRegistrationEvent($user));
In the above example, after I have saved my user I dispatch them a welcome
email. I created a "EmailSubscriber" because I may want to add more events
that dispatch emails. One example would be adding a "updateEmail"
method/event to EmailSubscriber that would be triggered when a user changes
their email address. The updateEmail method would dispatch an email with a
confirmation link. If you wanted to send a text message on registration,
I'd create a new EventSubscriber called TextMessageSubscriber, that would
look very similar to EmailSubscriber but would send a text message.
I'd once again recommend not using Doctrine's EventManager for domain
events. You should use the EventManager provided by your framework and if
it doesn't have one use Symfony's.
