With this datasource you can easily add users to your Mailchimp newsletter. It works with CakePHP 2.0+.

Please check the original blogpost on our devblog for more background information.

Copy the plugin into the APP/Plugin folder and make sure it is loaded using CakePlugin::loadAll(), for example.

Add the $mailchimp datasource to APP/Config/database.php

public $mailchimp = array(
	'datasource' => 'Mailchimp.MailchimpSubscriberSource',
	'apikey' => 'YOUR_API_KEY',
	'listId' => 'YOUR_LIST_ID',
	'baseUrl' => 'http://us1.api.mailchimp.com/1.2/' // or another one, depending on the API version you use
);

For BC you can also use the Configure class to set the API data:

$config['Mailchimp'] = array(
	'apiKey' => 'YOUR_API_KEY',
	'defaultListId' => 'YOUR_LIST_ID',
);

Include the Model where you need it via

$this->MailchimpSubscriber = ClassRegistry::init('Mailchimp.MailchimpSubscriber');

When you've set the datasource up correctly, you will now be able to do stuff like $this->MailchimpSubscriber->save($this->request->data), or call other regular Model methods (like Model::find) from any controller that uses the MailchimpSubscriber model.

Possibly my Tools plugin for the admin backend (optional)
