Email Template v0.2.2

This component facilitates for the sending of emails using Swiftmailer.

Usage

This library is made up of a few key concepts. A Message, Prepare and Mailer. All three are required to construct the email, prepare the body and send the email. Optionally, you may also choose to add Attachment to your Message.

Message

Constructs the bare bones of an email, such as who it's going to, the subject line etc.

Email

The Email class is the most basic of all emails, and simply allows you to create an email with to, cc, bcc, from, subject and body information. The default content type for Email messages is 'text/plain'.

$email = new EmailTemplate\Message\Email;
$email->to(['[email protected]']);
$email->from('[email protected]', 'The Webmaster');
$email->subject('Hello there');
$email->body('Hello there!');

EmailTemplate

The EmailTemplate class builds on the Email class, but instead allows you to load in a template with placeholders. This template is then parsed and prepared with your data to allow you to create dynamic emails. The default content type for EmailTemplate messages is text/html.

$emailTemplate = new EmailTemplate\Message\EmailTemplate('/path/to/email-templates');

// Retrieve your email template (/path/to/email-templates/your-email-template.html)
$emailTemplate->load('your-email-template')

// You can specify a name if you like
$emailTemplate->to(['[email protected]' => 'John Smith']);

$emailTemplate->from('[email protected]');
$emailTemplate->subject('Hello there');

Mesages with Fallback

You can specify both plain text and HTML alternatives to an email by specifiying a content type when setting the body of the email:

$email->body('<strong>This is HTML</strong>', 'text/html');
$email->body('This is text', 'text/plain');

If the content type is omitted, the default content type will be used (text/plain for Email and text/html for EmailTemplate)

Attachment

All Message classes are able to support attachments via their attachment method. An attachment can be either the path to the file, or the actual contents of the file itself. Multiple attachments can be added with subsequent calls to the attachment method.

This example is a path to the attachment:

// Create the attachment
$attachment = new EmailTemplate\Attachment\Attachment;
$attachment->filename('hello.txt');
$attachment->data('/path/to/your/file', true);

// Now attach it!
$email->attachment($attachment);

This example is an inline attachment, an image called waves.png. Note the disposition() method that will attempt to inline the image instead of just attaching it to the message.

// Create the attachment
$attachment = new EmailTemplate\Attachment\Attachment;
$attachment->filename('waves.png');
$attachment->data({wavesbinarydatahere});
$attachment->contentType('image/png');
$attachment->disposition('inline');

// Now attach it!
$email->attachment($attachment);

Prepare

This is what generates the actual body of an email template. It should be used in conjuction with Message\EmailTemplate.

VsprintPrepare

This is a very simple handler, which accepts the template and an array of parameters to be included.

It can be used standalone:

$prepare = new \EmailTemplate\Prepare\VsprintfPrepare();
$parsed = $prepare->render('Hi %s', array('there'));

Or assuming $emailTemplate from the above example:

// This will be used to replace the placeholders in the template
$emailTemplate->prepare(new \EmailTemplate\Prepare\VsprintfPrepare(), ['Brendan']);

// Or you can inject the parsed template
$emailTemplate->setParsedTemplate($parsed);

MustachePrepare

This allows you to markup your template using Mustache.

It can be used standalone:

$prepare = new \EmailTemplate\Prepare\MustachePrepare();
$parsed = $prepare->render('Hi {{name}}', array('name' => 'there'));

Assuming $emailTemplate from the above example:

// This will be used to replace the placeholders in the template
$emailTemplate->prepare(new \EmailTemplate\Prepare\MustachePrepare(), ['Brendan']);

// Or you can inject the parsed template
$emailTemplate->setParsedTemplate($parsed);

Mailer

This is how the emails will actually be sent.

SwiftMailer

For the moment, sending of Emails is abstracted to use the Swiftmailer class.

// Now lets prepare the mailer
$mailer = new \EmailTemplate\Mailer();

// Set the mail configuration
$mailer->setConfiguration([
    'host' => 'your host',
    'port' => 'your port'
    'user' => 'your username',
    'password' => 'your password'
]);

// If you want logging, you can pass a Monolog handler to do so
$mailer->setLogger($logger);

// The mailer can handle any email that implements the MessageInterface
$mailer->send($email); // This can also be $emailTemplate
