Templated emailer

This library simply ties together Symfony's powerful templating engine with the flexibility of Swiftmailer, allowing you to send templated emails easily.

Setup

Without DI

If you're not using DI (or don't know what DI is) there is a helpful factory to create the mailer:

$emailer = \Silktide\TemplatedEmailer\TemplatedEmailerFactory::create('/path/to/templates');

The only required argument is the path to the folder containing your email templates (see Creating a template below).

By default, the factory will set up the class to use PHP's mail() function to send your mail and Symfony's PhpEngine for templating. You can optionally provide a Swiftmailer transport class as the second argument if you want to use a different transport, e.g. SMTP. Here's an example of using an alternative transport:

$transport = \Swift_SmtpTransport::newInstance('smtp.example.org', 25)
            ->setUsername('your username')
            ->setPassword('your password');
$emailer =  \Silktide\TemplatedEmailer\TemplatedEmailerFactory::create('/example', $transport);

Dependency injection / manual instantiation

The TemplatedEmailer class just requires two arguments, a Symfony template engine and an instance of Swift_Mailer:

/**
* @var \Symfony\Component\Templating\EngineInterface
*/
$templateEngine;

/**
* @var \Swift_Mailer
*/
$emailClient;

$emailer = new \Silktide\TemplatedEmailer\TemplatedEmailer($templateEngine, $emailClient);

Creating a template

Templates are using Symfony's well documented template library. Here's a very basic example:

<h1>An email from myApp</h1>
<p>Dear <?php echo $recipientName; ?></p>
<p><?php echo $message; ?>

The variables in the message are passed through as an array to the send() method (see usage below).

Usage

Before any emails can be sent, you must set a sender:

$emailer->setSender('pat@postman.com', 'Postman Pat');

Sending an email now just requires a recipient, subject, template filename and context:

$this->mailer->send(
    'mrsgoggins@greendalepo.com',
    'Jess the black and white cat',
    'anEmail.php',
    [
        'recipientName' => 'Mrs Goggins',
        'message' => 'Hello!'
    ]
);

The recipient can also have a name set by using an array in the format ['email@host.tld' => 'Friendly Name']:

$this->mailer->send(
    ['mrsgoggins@greendalepo.com' => 'Mrs Goggins'],
    'Jess the black and white cat',
    'anEmail.php',
    [
        'recipientName' => 'Mrs Goggins',
        'message' => 'Hello!'
    ]
);
