SimplePie CakePHP Component
This article is also available in the following languages:
SimplePHP is a PHP class for retrieval and parsing of RSS feeds. This is a wrapper to that class making it easy to use in the CakePHP framwork. Much of this component is taken from the work of Scott Sansoni (http://cakeforge.org/snippet/detail.php?type=snippet&id=53). This is mostly an update so the component works with the lastest version of SimplePie.
Download
You can download a zip of the component at http://sandbox.pseudocoder.com/demo/simplepie.Usage
- CakePHP either 1.1 or 1.2
- Download SimplePie 1.0.1 (http://simplepie.org/downloads) and unzip the contents. Move the simplepie.inc to one of the vendors folders. Rename the file to simplepie.php. I like to put the file in the sub folder with the README.txt and LICENSE.txt for easy reference.
- Download the component (or paste the full code from below) and unzip it to app/controllers/components.
- Include the component in any controller that will need it.

class SimplepieComponent extends Object {
var $cache;
function __construct() {
$this->cache = CACHE . 'rss' . DS;
}
function feed($feed_url) {
//make the cache dir if it doesn't exist
if (!file_exists($this->cache)) {
$folder = new Folder();
$folder->mkdirr($this->cache);
}
//include the vendor class
vendor('simplepie/simplepie');
//setup SimplePie
$feed = new SimplePie();
$feed->set_feed_url($feed_url);
$feed->set_cache_location($this->cache);
//retrieve the feed
$feed->init();
//get the feed items
$items = $feed->get_items();
//return
if ($items) {
return $items;
} else {
return false;
}
}
}
?>
?>
Controller Class:
<?php $items = $this->Simplepie->feed('http://feeds.feedburner.com/pseudocoder');
?>
View Template:
foreach($items as $item) {
echo $html->link($item->get_title(), $item->get_permalink()) . '<br />';
}
1) I'm trying to do a basic setup using a static feed address (as above) and I get an undefined variable for items in the view and therefore an invalid argument for the foreach. I'm using cake 1.2.7 and the only download of simplepie I seem to be able to get my hands on 1.2. I am slightly uncertain as to whether I've named the component file correctly 'simplepie.php', same as the file that goes in the vendors directory, but I don't think I would get as far as I have if I had done that wrong.
2) In general, my intention is to have a mysql table with a list of blog rss feeds which includes basic info such as title but also a snippet of text plus time and date from the most recent post. Where am I actually running logic that associates said snippet with my mysql table -- should that be in the model? There are some allusions in the cookbook as to the potential of a model being an rss feed but I haven't seen any practical examples. Plus the specific feeds which are being accessed vary according to what's in the list of feeds. It's not like I want a single rss feed to neatly populate a table -- it's more like I have a feed address in a mysql row and I want that to be the basis for two other rows to become populated.
Any advice on either point would be greatly appreciated.
For Cake 1.3 replace the Component's line
$folder->mkdir($this->cache);with
$folder->create($this->cache);First one was explained above - add the following before the class:
App::import('Vendor', 'Simplepie', array('file' => 'simplepie/simplepie.php'));
The second one is regarding the cache - correct the following, from:
$folder->mkdirr($this->cache);to:$folder->mkdir($this->cache);This should make it work perfectly!
I am new to cake,
Does anyone know the solution for this please?
Thks.
And vendor() is deprecated. App::import('Vendore', ...) should be used.
Very simple to use and exposes details like how it's suggested in comments here.
the only pb i have is i m loosing connexion infos (login, pass...)and i can"t find why.
any idea ?
There is a fix for this but I don't know how to apply it in the cakephp environment, here's the link: http://simplepie.org/wiki/faq/i_m_getting_memory_leaks
Any help with this would be appreciated.
On 1.2.x RC1, I got this error.
All you need to do is change the line (simplepie component):
from:
Component Class:
<?phpvendor('simplepie/simplepie');
?>
to:
Component Class:
<?phpApp::import('Vendor', 'simplepie/simplepie');
?>
Hope this helps!
Great tutorial about integrating SimplePie in a cakePHP application.
SimplePie 1.0.1 cann't download any more at the website, only SimplePie 1.1. The new version gaves the warning:
Warning (2): preg_match() [function.preg-match]: Compilation failed: nothing to repeat at offset 551 [CORE\app\vendors\rss\simplepie.php, line 11599] Warning (2): preg_match() [function.preg-match]: Compilation failed: nothing to repeat at offset 497 [CORE\app\vendors\rss\simplepie.php, line 11687] Warning (2): preg_match() [function.preg-match]: Compilation failed: nothing to repeat at offset 497 [CORE\app\vendors\rss\simplepie.php, line 11753]
Does somebody now where I can downlaod SimplePie 1.0.1 or is there an update of the component for this problem?
