Scope
This article is intended for use with Kohana 2.x version. I have tested only with the latest, which is 2.3.4 as of today.
Kohana’s « Feed » helper
The official documentation of the helper is located here :https://docs.kohanaphp.com/helpers/feed
With this helper you can easily create an RSS feed, however the method doesn’t natively support nested tags. So … won’t work and you’ll get this error :
1 | SimpleXMLElement::addChild() expects parameter 2 to be string, array given |
Workaround : syntax in your controller
Logic tends to nest your tags into a sub-array, like this :
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 | public function rss() { $info = array('title' => 'Christian Lapie', 'notes' => 'Latest updates'); $items = ORM::factory('article') ->where('statut', 'publie') ->orderby('date', 'desc') ->find_all(); $rssitems = array(); foreach($items as $item) { $rssitems[] = array( 'title' => $item->titre, 'link' => Kohana::config('site.url_site').'/oeuvres/'.$item->id.'/'.url::title($item->titre), 'description' => $item->soustitre, 'author' => 'Christian Lapie', 'pubDate' => date("D, d M Y H:i:s +0100", strtotime($item->date)), 'image' => array( 'url' => Kohana::config('site.url_site').'/IMG/arton'.$item->id.'.jpg', 'title' => $item->titre, 'link' => Kohana::config('site.url_site').'/oeuvres/'.$item->id.'/'.url::title($item->titre) ) ); } echo feed::create($info, $rssitems); exit();} |
(look carefully at the image key and its sub-pairs)
Editing Kohana’s core
It turns out to be pretty simple.
You will open the following file :
1 | /system/helpers/feed.php |
Then find the following lines (around 114) :
1 2 | // Add the info to the row$row->addChild($name, $value); |
Finally replace the block with this :
1 2 3 4 5 6 7 8 9 | // Add the info to the rowif (is_array($value)) { $temp = $row->addChild($name); foreach($value as $key1 => $value1) { $temp->addChild($key1, $value1); }} else { $row->addChild($name, $value);} |
Et voilà !
Now you can have a nicely valid tag :
Result
1 2 3 4 5 6 7 8 9 10 11 12 | <item> <title>Les secrets d'un temps immense</title> <link>https://lapie.localhost/oeuvres/318/les-secrets-dun-temps-immense</link> <description>Varsovie, Blonie, Pologne (Poland)</description> <author>Christian Lapie</author> <pubDate>Wed, 12 Jan 2011 00:00:00 +0100</pubDate> <image> <url>https://lapie.localhost/IMG/arton318.jpg</url> <title>Les secrets d'un temps immense</title> <link>https://lapie.localhost/oeuvres/318/les-secrets-dun-temps-immense</link> </image></item> |
You can add optional parameters such as Width, Height… see the RSS Specifications here.

Great post. Exactly solved my problem.
In my case the file that need to be revised is located here:
SYSPATH/classes/Kohana/Feed.php [ 163 ]
Thanks for sharing.
Glad it helped!
