Class Mailer

Mailer base class.

Mailer classes let you encapsulate related Email logic into a reusable and testable class.

Defining Messages

Mailers make it easy for you to define methods that handle email formatting logic. For example:

class UserMailer extends Mailer
{
    public function resetPassword($user)
    {
        $this
            ->subject('Reset Password')
            ->to($user->email)
            ->set(['token' => $user->token]);
    }
}

Is a trivial example but shows how a mailer could be declared.

Sending Messages

After you have defined some messages you will want to send them:

$mailer = new UserMailer();
$mailer->send('resetPassword', $user);

Event Listener

Mailers can also subscribe to application event allowing you to decouple email delivery from your application code. By re-declaring the implementedEvents() method you can define event handlers that can convert events into email. For example, if your application had a user registration event:

public function implementedEvents()
{
    return [
        'Model.afterSave' => 'onRegistration',
    ];
}

public function onRegistration(Event $event, Entity $entity, ArrayObject $options)
{
    if ($entity->isNew()) {
         $this->send('welcome', [$entity]);
    }
}

The onRegistration method converts the application event into a mailer method. Our mailer could either be registered in the application bootstrap, or in the Table class' initialize() hook.
