Mailman

A CodeIgniter library for using various third-party email systems.

Why is this useful?

Many web-apps are using email platform services instead of their own server or SMTP solutions. Mailman provides a way for you to use any of these third-party libraries interchangeably.

For instance, if you reach a daily limit on AmazonSES, you can quickly and effortessly switch over to Mandrill by simply changing a configuration, instead of editing your code everywhere emails are sent.

The nerdier reason why

This library has a generic Interface and a implementing Abstract class. Mail transport classes such as AmazonSES or Mandrill extend this abstract class and compose their related third-party libraries (amazon_ses, mandrill PHP sdk).

Why is this cool? This means that any code you write in your application using the Mailman library will always use the same methods no matter which email transport you use.

If you change from Amazon to Mandrill or another third-party email system, you only need to change a configuration, rather than changes in your code.

OOP is good!

Dependencies

This library will depend on any third-party email libraries you use.

Out of the box, Mailman uses Amazon SES, which depends on this SES library by Joël Cox (Not included).

Update!

Mailman now also supports Mandrill for use as a transport! Download the Mandrill library.

Documentation

Note:

This library uses views for the email bodies, in conjunction with the CI template parser library to populate those templates with your data.

Parameters needed for sending email:

transport - Which email service are you using (default: AmazonSes)
to - A valid email address, or array or email addresses
from - A valid email address
subject - A subject line
template_html - Path to the view file for the HTML email
template_alt - Path to the view file for the plain-text version of the email
template_data - An array of data to be parsed by the CI template parser library and injected into the html and alternate plain text view files.

Optional Parameters, depending on transport.

from - A valid email address.
cc - A valid email address
bcc - A valid email address

Class Constants:

Mailmail::MAILMAN_TRANSPORT_DEFAULT = 'AmazonSes'
Mailmail::MAILMAN_TRANSPORT_AMAZONSES = 'AmazonSes'
Mailmail::MAILMAN_TRANSPORT_MANDRILL = 'Mandrill'

Usage Examples:

Methods are accessible via Static methods, or via classic CI library calls. Here's some sample usage.

//Load Library
$this->load->library('mailman');



//Classic CI implementations
$this->mailman->setTransport(Mailman::MAILMAN_TRANSPORT_AMAZONSES);

$this->mailman->sendmail(array(
	'to' => 'example@example.com',
	'from' => 'system@example.com',
	'from_name' => 'Do Not Reply',
	'cc' => 'another@example.com',
	'bcc' => 'sneaky@example.com',
	'subject' => 'Test Email',
	'template_html' => 'email/example',
	'template_alt' => 'email/example_alt',
	'template_data' => array(
	 		'headline' => 'Example Headline',
	 		'body' => 'Example Message.',
	 		'example list' => array(
	 			'List Item 1',
	 			'List Item 2',
	 			'List Item 3'
	 		)
	 	)
));

## Alternatively, chain the methods
$this->mailman->setTransport(Mailman::MAILMAN_TRANSPORT_AMAZONSES)->sendmail(array(
	'to' => 'example@example.com',
	'subject' => 'Test Email',
	'template_html' => 'email/example',
	'template_alt' => 'email/example_alt',
	'template_data' => array(
	 		'headline' => 'Example Headline',
	 		'body' => 'Example Message.',
	 		'example list' => array(
	 			'List Item 1',
	 			'List Item 2',
	 			'List Item 3'
	 		)
	 	)
));

## OR just let mailman default to AmazonSes (Current set default)
$this->mailman->sendmail(array(
	'to' => 'example@example.com',
	'subject' => 'Test Email',
	'template_html' => 'email/example',
	'template_alt' => 'email/example_alt',
	'template_data' => array(
	 		'headline' => 'Example Headline',
	 		'body' => 'Example Message.',
	 		'example list' => array(
	 			'List Item 1',
	 			'List Item 2',
	 			'List Item 3'
	 		)
	 	)
));

## OR change the default yourself and set transport to it:
$this->mailman->setTransport(Mailman::MAILMAN_TRANSPORT_DEFAULT)->sendmail(array(
	'to' => 'example@example.com',
	'subject' => 'Test Email',
	'template_html' => 'email/example',
	'template_alt' => 'email/example_alt',
	'template_data' => array(
	 		'headline' => 'Example Headline',
	 		'body' => 'Example Message.',
	 		'example list' => array(
	 			'List Item 1',
	 			'List Item 2',
	 			'List Item 3'
	 		)
	 	)
));


//Super-cool static method way
$this->mailman::instance()->setTransport(Mailman::MAILMAN_TRANSPORT_AMAZONSES);

## OR
$this->mailman::instance()->setTransport(Mailman::MAILMAN_TRANSPORT_AMAZONSES)->sendmail( ... );

## OR default to AmazonSes
$this->mailman::email(array(
	'to' => 'example@example.com',
	'subject' => 'Test Email',
	'template_html' => 'email/example',
	'template_alt' => 'email/example_alt',
	'template_data' => array(
	 		'headline' => 'Example Headline',
	 		'body' => 'Example Message.',
	 		'example list' => array(
	 			'List Item 1',
	 			'List Item 2',
	 			'List Item 3'
	 		)
	 	)
));

My library does more, how do I get to it?

If the email transport does more, or you need extra options, there is an available function getCore() in each transport, which will give you direct access to that library. Here's an example.

$this->load->library('mailman');

$this->mailman->setTransport(Mailman::MAILMAN_TRANSPORT_MANDRILL);

$mandrill = $this->mailman->getTransport()->getCore();

// Lets get a list of Mandrill webhooks we have set up, for instance
$webhooks = $mandrill->webhooks_list();

print_r($webhooks);

To Do:

Make email transport used a config value, override-able in code (instead of current in-code selection with default)
Add more libraries (Sendgrid, Postmark)
Support arrays for multiple to, cc, bcc fields [as email systems allow]
Wiki for platform-specific and extra information
