Rendering a List view of Zoo items using Code
 

Zoo is one of the most versatile CCK extensions available in Joomla. Its flexible & at the same time easy to use for end users. Inspite of these positive points, there are times when you have to dive into development & Zoo APIs to develop your own custom views.

In this particular case, we wanted to develop a List/Grid view with Zoo ( of a particular Content Type)  which showed all Zoo attributes in a table view for easier data viewing on the frontend for content managers. In this blog, we will tell you just how to go about doing that !

You must be thinking what's the big deal ? Just fetch the records based on submission id & display them in any way you want.

Well... Its not as easy as that, as Zoo uses JSON to store record data which is great.. But its makes it a bit difficult to render zoo elements. Its quite complicated to get zoo item details from database by executing queries.Even if you manage it won't be robust . To get related records from table you have to deal with a 36 key string, which zoo uses as field identifier. So lets get away from this hassle of doing it with your own code. Thats not the right way to go about it anyways !

Lets take a look at how best to do that using the Zoo APIs.

// Get the Zoo Instance
$zapp = App::getInstance('zoo');

$items = $app->table->item->all(array('conditions' => 'id = '.$Zoo_Item_id)); 

//$Zoo_Item_id must be zoo item id of which you want to render details
 
foreach($items as $item)
{
 foreach ($item->getElements() as $id => $element)
 {
  echo $element->render(); 
 }
}
