#Gos Mailer Bundle#

This project is currently in development, please take care.

Provide an easy way to architecture your mail system on huge projects. Easy to maintains, dedicated class and build your email like you build your form. If you use Symfony/Form, it's really easy to you, MailBuilder have the same API :)

Installation

You need to have composer to install dependencies.

{
    "require": {
        "gos/mailer-bundle": "{last stable version}"
    }
}

Then run the command on the root of your projectcomposer update

Add this line in your AppKernel.php

$bundles = array(

	//Other bundles
    new Gos\Bundle\MailerBundle\GosMailerBundle(),
);

Usage

First step, we will create an email, each email have his own class like this :

<?php
//Acme/DemoBundle/Mail/RegistrationMail.php

use Gos\Bundle\MailerBundle\Manager\Transport\Mail;
use Gos\Bundle\MailerBundle\Manager\Transport\Builder\MailBuilderInterface;
use Acme\DemoBundle\Entity\User;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;

class RegistrationMail extends Mail
{
    /**
     * @var User
     */
    protected $user;

    /**
     * @var array
     */
    protected $applicationInfo;

    /**
     * Dependency related to our email.
     * @param $applicationInfo
     */
    public function __construct($applicationInfo)
    {
        $this->applicationInfo = $applicationInfo;
    }

    /**
     * Dependency related to our email.
     * @param User $user
     */
    public function setUser(User $user)
    {
        $this->user = $user;
    }

    /**
     * @param MailBuilderInterface $builder
     * @param array                $options
     */
    public function buildMail(MailBuilderInterface $builder, Array $options)
    {
    	//Build you header fields
        //$builder->($headerType, $value, Array $options)
        $builder->add('to', $this->user->getEmail());

        $builder->add('subject', 'mail.subject', array(
            'parameters' => array('%username%' => $this->user->getUsername(),
            '%app_name%' => $this->applicationInfo['name']),
            'translation_domain' => 'registration'
        ));

        $builder->add('from', '[email protected]');

        /**
         Using the bundle configuration you can make shortcut to centralized emails
         $builder->add('from', 'no_reply');
        */
    }

    /**
     * Send some parameters to the view
     * @param  array $options
     * @return array
     */
    public function finishView(Array $options)
    {
        return array(
            'user' => $this->user
        );
    }

    /**
     * Define options of you
     * @param OptionsResolverInterface $resolver
     */
    protected function setDefaultOptions(OptionsResolverInterface $resolver)
    {
        $resolver->setDefaults(array(
            'template' => 'AcmeDemoBundle:Mail:registration.html.twig'
            //'content_type' => 'text/html' (by default)
        ));
    }

    /**
     * Name of you mail (must be unique)
     * @return string
     */
    public function getName()
    {
        return 'acme_demo_mail_registration';
    }
}

From here, RegistrationMail is an abstracted representation of your email. Now register it as service.

services:
    acme.demo_bundle.mail.registration:
        class: Acme\DemoBundle\Mail\RegistrationMail
        public: false
        arguments:
            - %project%
        tags:
            - { name: mail }

Send the email :

<?php
//Acme/DemoBundle/EventListener/UserSubscriber.php

use Gos\Bundle\MailerBundle\Manager\Transport\MailFactory;
use Gos\Bundle\MailerBundle\Manager\Transport\MailTransportManager;
use Gos\Bundle\ResourceBundle\ClassInterface\ActiveStateInterface;
use Gos\Bundle\UserBundle\Events\UserLifeCycleEvent;
use Gos\Bundle\UserBundle\Events\UserLifeCycleEvents;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;


class UserSubscriber implements EventSubscriberInterface
{
    /**
     * @var \Gos\Bundle\MailerBundle\Manager\Transport\MailTransportManager
     */
    protected $mailTransportManager;

     /**
     * @var \Gos\Bundle\MailerBundle\Manager\Transport\MailFactory
     */
    protected $mailFactory;


    /**
     * Inject our dependencies
     * @param MailTransportManager $mailTransportManager
     * @param MailFactory          $mailFactory
     */
    public function __construct(MailTransportManager $mailTransportManager, MailFactory $mailFactory)
    {
        $this->mailTransportManager = $mailTransportManager;
        $this->mailFactory = $mailFactory;
    }

    /**
     * @return array
     */
    public static function getSubscribedEvents()
    {
        return [
            UserLifeCycleEvents::NEW_USER => array('onNewUser', 0),
        ];
    }

    /**
     * @param UserLifeCycleEvent $event
     */
    public function onNewUser(UserLifeCycleEvent $event)
    {
		$user = $event->getUser();

        //Create our email
        $registrationMail = $this->mailFactory->createNamed('acme_demo_mail_registration');
        $registrationMail->setUser($user);

        /**
        * The factory is not needed in our case because we send only one mail. Factory avoid
        * to inject many dependencies, because you can directly inject acme.demo_bundle.mail.registration
        *
        * public function __construct(RegistrationMail $registrationMail, MailTransportManager $manager){
        *   $registrationMail->setUser($user);
        *  	$manager->send($registrationMail);
        * }
        *
        **/

        //Send it
        $this->mailTransportManager->send($registrationMail);
    }
}

Events

When mail has send, we dispatch an event named : gos.mailer_bundle.mail_send (MailerEvents::MAIL_SEND) events.

Event class :

<?php
namespace Gos\Bundle\MailerBundle\Events;

use Symfony\Component\EventDispatcher\Event;

class OnEmailSendEvent extends Event
{
    protected $message;

    public function __construct(\Swift_Message $message)
    {
        $this->message = $message;
    }

    /**
     * @return \Swift_Message
     */
    public function getMessage()
    {
        return $this->message;
    }
}

Running the tests:

PHPUnit 3.5 or newer together with Mock_Object package is required. To setup and run tests follow these steps:

• go to the root directory of fixture
• run: composer install --dev
• run: phpunit
