zfcuser add user role after registration - zend-framework

Question

I'm using Zend Framework 2 with ZfcUser, BjyAuthorize and Doctrine for the database. Registration etc. works very well so far. My problem is, that registered users have no role assigned, so i want to add the role "user" to the user during registration.
I think i could attach this to the "register" event, but i don't know how to do that.
I hope someone can help me ...
(i used this tutorial for setting up zfcuser etc. http://samminds.com/2013/03/zfcuser-bjyauthorize-and-doctrine-working-together/)
public function onBootstrap(MvcEvent $e)
{
$zfcServiceEvents = $e->getApplication()->getServiceManager()->get('zfcuser_user_service')->getEventManager();
$zfcServiceEvents->attach('register', function($e) {
$user = $e->getParam('user');
// probably the role must be added here, with $user->addRole();
// but how do i get the user Role Entity to add from DB?
});

Building on DangelZM's answer, and using another reference (see link at end of my post) about the Event Manager, I came up with this solution which organizes the potential ZfcUser event listeners out into a user listener object.
Note: I created my own user module called NvUser, so depending on the name of your module you'll have to replace all references of NvUser to your user module name.
Summary
I created an NvUserListener object that can itself attach event listeners to the shared event manager, and house the event listener callbacks.
Inside NvUser/Module.php:
<?php
namespace NvUser;
use Zend\Mvc\MvcEvent;
use NvUser\Listener\NvUserListener;
class Module
{
public function onBootstrap(MvcEvent $mvcEvent)
{
$em = $mvcEvent->getApplication()->getEventManager();
$em->attach(new NvUserListener());
}
}
Inside NvUser/src/NvUser/Listener/NvUserListener.php:
<?php
namespace NvUser\Listener;
use Zend\EventManager\AbstractListenerAggregate;
use Zend\EventManager\EventManagerInterface;
use Zend\EventManager\Event;
class NvUserListener extends AbstractListenerAggregate
{
public function attach(EventManagerInterface $events)
{
$sharedManager = $events->getSharedManager();
$this->listeners[] = $sharedManager->attach('ZfcUser\Service\User', 'register', array($this, 'onRegister'));
$this->listeners[] = $sharedManager->attach('ZfcUser\Service\User', 'register.post', array($this, 'onRegisterPost'));
}
public function onRegister(Event $e)
{
$sm = $e->getTarget()->getServiceManager();
$em = $sm->get('doctrine.entitymanager.orm_default');
$user = $e->getParam('user');
$config = $sm->get('config');
$criteria = array('roleId' => $config['zfcuser']['new_user_default_role']);
$defaultUserRole = $em->getRepository('NvUser\Entity\Role')->findOneBy($criteria);
if ($defaultUserRole !== null)
{
$user->addRole($defaultUserRole);
}
}
public function onRegisterPost(Event $e)
{
$user = $e->getParam('user');
$form = $e->getParam('form');
// Do something after user has registered
}
}
Inside NvUser/config/module.config.php:
<?php
namespace NvUser;
return array(
'zfcuser' => array(
'new_user_default_role' => 'user',
),
);

Maybe it's not the best solution, but it works for me.
Add user_role_id option in config scope.
public function onBootstrap(MvcEvent $mvcEvent)
{
$zfcServiceEvents = $mvcEvent->getApplication()->getServiceManager()->get('zfcuser_user_service')->getEventManager();
$zfcServiceEvents->attach('register', function($e) use($mvcEvent) {
$user = $e->getParam('user');
$em = $mvcEvent->getApplication()->getServiceManager()->get('doctrine.entitymanager.orm_default');
$config = $mvcEvent->getApplication()->getServiceManager()->get('config');
$defaultUserRole = $em->getRepository('SamUser\Entity\Role')->find($config['user_role_id']);
$user->addRole($defaultUserRole);
});
}
Maybe someone will offer better solution.

This work too.
public function onBootstrap(MvcEvent $mvcEvent)
{
$zfcServiceEvents = $mvcEvent->getApplication()-getServiceManager()->get('zfcuser_user_service')->getEventManager();
$zfcServiceEvents->attach('register', function($e) use($mvcEvent) {
$user = $e->getParam('user');
$em = $mvcEvent->getApplication()->getServiceManager()-get('doctrine.entitymanager.orm_default');
$defaultUserRole = $em->getRepository('SamUser\Entity\Role')-find('id_of_your_role_on_table_role_for_example: '2'');
$user->addRole($defaultUserRole);
});
}

I just used a MySQL trigger
DROP TRIGGER IF EXISTS `user_role_after_insert_trig`;
DELIMITER //
CREATE TRIGGER `user_role_after_insert_trig` AFTER INSERT ON `user`
FOR EACH ROW begin
insert into user_role_linker (user_id,role_id) values (new.user_id, 5);
end
//
DELIMITER ;
