This tutorial help us in creating RSS Feed in cakephp framework. For more on RSS Feed see the link below:

"http://findnerd.com/account#url=/list/publish/What-is-RSS-Rich-Site-Summary-/2965/"

Let use take a table users in the database.

Step 1: We make changes in our routes.php file

path: projectfile/app/core/routes.php

<?php

Router::parseExtensions('rss');

/**
 * Load the CakePHP default routes. Only remove this if you do not want to use
 * the built-in default routes.
 */
require CAKE . 'Config' . DS . 'routes.php';

?>

Step 2: Now we will add a 'RequestHandler' and 'Paginator' component in the UsersController.php file

path: projectfile/app/Controller/UsersController.php

<?php

class UsersController extends AppController {

    var    $uses          = array('User');
    public $components   = array( 'Paginator','RequestHandler');
    public $helpers            = array('Html');

public function index(){    

        $this->User->recursive = 0;
        $this->set('users',$this->paginate());
    }
}

?>

Step 3: Now we will create rss layout as we create a layout for your view file.

Path: projectfile/app/View/Layout/rss/default.ctp

<?php
    echo $this->rss->header();
    $channel = $this->rss->channel(array(),$ChannelData,$content_for_layout);
    echo $this->rss->document(array(),$channel);
?>

channel() => it is rss helper method.

Header() => it is rss helper method.

Document()=> it is rss document method. It takes 2 parameters one is empty array and another is the contents of the rss

Step 4: Now we will create rss view file and this view file will be created for the index action of in UserController.php file.

Path: projectfile/app/View/User/rss/index.ctp

<?php

$channelData=array(
'title'=>'Our Current Users',
'link'=>$this->html->url(array(
'controller'=>'users',
'action'=>'index',
'ext'=>'rss',
)),
'description'=>'List of the users registered with the app',
'language'=>'eng-us'
);

$this->set('ChannelData',$channelData);

foreach($users as $user){

    echo $this->rss->item(
        array(),
        array(
        'Title'=>$user['User']['user_name'],
        'link'=>array(
            'controller'=>'users',
            'action'=>'view', $user['User']['id'],
        ),
        'guid'=>array(
            'controller'=>'users',
            'action'=>'view', $user['User']['id'],
        ),
        'description'=>"<div>".strip_tags($user['User']['email'])."</div>",
        'registrationDate'=>$user['User']['created'],
        )
    );
}    
?>

Step 5: Now to see the RSS feed use the following url:

url: yourdomain/projectfilename/controller/index.rss
