Zend Framework 2 : ViewFeedStrategy : Generating Feeds

Posted in Tutorial PHP, Zend Framework 2 by samsonasik on September 18, 2012

Beside DefaultRenderingStrategy, ViewPhpRendererStrategy, and ViewJsonStrategy, Zend Framework 2 has ViewFeedStrategy that can be used in rendering generated feeds. It use FeedModel to utilize the strategy.

The enable the ViewFeedStrategy, we simply configure it in the module’s config.php :

return aray(
   'controllers'=> array( /* common code */ ),
   'router' => array( /* common code */ ),

   'view_manager' => array(
        'strategies' => array(

let’s test it :

namespace ZendSkeletonModule\Controller;

use Zend\Mvc\Controller\AbstractActionController;
use Zend\Feed\Writer\Feed;
use Zend\View\Model\FeedModel;

class SkeletonController extends AbstractActionController
    public function feedAction()
        $feed = new Feed();
        $feed->setTitle('Feed Example');
        $feed->setFeedLink('http://ourdomain.com/rss', 'atom');
            'name'  => 'admin',
            'email' => 'contact@ourdomain.com',
            'uri'   => 'http://www.ourdomain.com',
        $feed->setDescription('Description of this feed');

        //fake data...
        $data = array(
            0 => array('title' => 'my 1st post', 'link' => 'http://ourdomain.com/1stpost',
                       'content'=> 'summary of 1st post',
                       'date_created' => '2012-01-01 00:00:00',
                       'date_created' => '2012-01-01 00:00:00'
            1 => array('title' => 'my 2nd post', 'link' => 'http://ourdomain.com/2ndpost',
                       'content'=> 'summary of 2nd post',
                       'date_created' => '2012-02-01 00:00:00',
                       'date_created' => '2012-02-01 00:00:00'),
            2 => array('title' => 'my 3rd post', 'link' => 'http://ourdomain.com/3rdpost',
                       'content'=>'summary of 3rd post',
                       'date_created' => '2012-03-01 00:00:00',
                       'date_created' => '2012-03-01 00:00:00'),

        foreach($data as $row)
            //create entry...
            $entry = $feed->createEntry();




        $feedmodel = new FeedModel();

        return $feedmodel;

Generated feeds :

Done !

    Looks nice and tested,
    maybe it would even be possible to have some kind of mapper for a db result set which would make it easier,
    but for a simple application this should be enough.

    Zend Framework 2 has View FeedStrategy that can be used in making produced for .It use Feed Model to implement the technique

    I’ve been struggling to get this working for a while now (being a ZF2 newbie). I’m very greatful to see this post because it shows me I’m on the right track. I’ve implemented it in much the same way that you have, but I get the error:

    PHP Fatal error: Uncaught exception ‘Zend\\View\\Exception\\RuntimeException’ with message ‘Zend\\View\\Renderer\\PhpRenderer::render: Unable to render template “blog/blog/atom”; resolver could not resolve to a file’

    Do you know why ZF2 is attempting to use PhpRenderer rather than FeedRenderer?

      It should be work. try to die it. by using FeedModel, you not pass it to the view.

        Thanks. It turned out to be a stupid typo. I spelled “strategies” as “stratgies”. I generally rely on my IDE to pick out badly named symbol references, which is why I hate referencing symbols as strings.

    This string isn’t need: $feed->export(‘rss’);
