Q:

Send email containing login and pass after registration

I am currently working on a Symfony2 project for managing user I installed the bundle FosUserBundle which is functional but I can not find how to send an email containing the username and password immediately after creating user, as I said I have two user: admin and user type, and it is the admin who will create the users with a form of creation that is the form of FOS Registration, changing between the two kind user is only the roles.

A:

You could hook into the EventDispatcher and send your own email rather than than the one generated by FOSUserBundle using your own Listener.
class EmailConfirmationListener implements EventSubscriberInterface
{
    private $mailer;
    private $router;
    private $session;

    public function __construct(MailerInterface $mailer,
            UrlGeneratorInterface $router)
    {
        $this->mailer = $mailer;
        $this->router = $router;
    }

    public static function getSubscribedEvents()
    {
        return array(
            FOSUserEvents::REGISTRATION_SUCCESS => array(
                array('onRegistrationSuccess',  -10),
            ),
        );
    }

    public function onRegistrationSuccess(FormEvent $event)
    {
        /** @var $user \FOS\UserBundle\Model\UserInterface */
        $user = $event->getForm()->getData();

        // send details out to the user
        $this->mailer->sendCreatedUserEmail($user);

        // Your route to show the admin that the user has been created
        $url = $this->router->generate('blah_blah_user_created');
        $event->setResponse(new RedirectResponse($url));

        // Stop the later events propagting
        $event->stopPropagation();
    }
}

Mailer service
use FOS\UserBundle\Model\UserInterface;
use FOS\UserBundle\Mailer\Mailer as BaseMailer;

class Mailer extends BaseMailer
{
    /**
     * @param UserInterface $user
     */
    public function sendAdminConfirmationEmailMessage(UserInterface $user)
    {
        /**
         * Custom template using same positioning as
         * FOSUSerBundle:Registration:email.txt.twig so that the sendEmailMessage
         * method will break it up correctly
         */
        $template = 'BlahBlahUser:Admin:created_user_email.txt.twig';
        $url = $this->router->generate('** custom login path**', array(), true);
        $rendered = $this->templating->render($template, array(
            'user' => $user,
            'password' => $user->getPlainPassword(),
        ));
        $this->sendEmailMessage($rendered,
            $this->parameters['from_email']['confirmation'], $user->getEmail());
    }
}

I think that would do it.. although I could be wrong.

A:

It's documented in the bundle's doc:
// src/Acme/UserBundle/Controller/RegistrationController.php
<?php

namespace Acme\UserBundle\Controller;

use Symfony\Component\HttpFoundation\RedirectResponse;
use FOS\UserBundle\Controller\RegistrationController as BaseController;

class RegistrationController extends BaseController
{
    public function registerAction()
    {
        $form = $this->container->get('fos_user.registration.form');
        $formHandler = $this->container->get('fos_user.registration.form.handler');
        $confirmationEnabled = $this->container->getParameter('fos_user.registration.confirmation.enabled');

        $process = $formHandler->process($confirmationEnabled);
        if ($process) {
            $user = $form->getData();

            /*****************************************************
             * Add new functionality (e.g. log the registration) *
             *****************************************************/
            $this->container->get('logger')->info(
                sprintf('New user registration: %s', $user)
            );

            if ($confirmationEnabled) {
                $this->container->get('session')->set('fos_user_send_confirmation_email/email', $user->getEmail());
                $route = 'fos_user_registration_check_email';
            } else {
                $this->authenticateUser($user);
                $route = 'fos_user_registration_confirmed';
            }

            $this->setFlash('fos_user_success', 'registration.flash.user_created');
            $url = $this->container->get('router')->generate($route);

            return new RedirectResponse($url);
        }

        return $this->container->get('templating')->renderResponse('FOSUserBundle:Registration:register.html.'.$this->getEngine(), array(
            'form' => $form->createView(),
        ));
    }
}
