Rss View

A CakePHP view class to quickly output RSS feeds

• By default template-less
• Very customizable regarding namespaces and prefixes
• Supports CDATA (unescaped content).

Configs

• 'limit' => 100 // batch of records per loop
• 'timeout' => null // in seconds
• 'fields' => array() // if not displayField
• 'updateFields' => array() // if saved fields should be different from fields
• 'validate' => true // trigger beforeValidate callback
• 'updateTimestamp' => false // update modified/updated timestamp
• 'scope' => array() // optional conditions
• 'callback' => null

Usage

You can config it in your actions like so:

$this->viewClass = 'Tools.Rss';

The nicer way would be to use extenions-routing and let CakePHP auto-switch to this view class. See the documentation on how to use view class mapping to automatically respond with the RssView for each request to the rss extension:

'rss' => 'Tools.Rss'

With the help of parseExtensions() and RequestHandler this will save you the extra view config line in your actions.

By setting the '_serialize' key in your controller, you can specify a view variable that should be serialized to XML and used as the response for the request. This allows you to omit views + layouts, if your just need to emit a single view variable as the XML response.

In your controller, you could do the following:

$this->set(array('posts' => $posts, '_serialize' => 'posts'));

When the view is rendered, the $posts view variable will be serialized into the RSS XML.

Note The view variable you specify must be compatible with Xml::fromArray().

If you don't use the _serialize key, you will need a view. You can use extended views to provide layout like functionality. This is currently not yet tested/supported.
