We would like to have our module do more than just display links to the reviews. It would be helpful to include a summary of the review along with each link, and have the opportunity to display a random review. However, the way we currently have it coded is not sufficient to handle different scenarios efficiently. To fix this, we will centralize the data functions into a helper class. Create a file called helper.php in the /modules/mod_reviews folder and add the following code to this new file:

<?php
defined( '_JEXEC' ) or die( 'Restricted access' );
class modReviewsHelper
{
function getReviews(&$params)
{
$items = $params->get('items', 1);
$db =& JFactory::getDBO();
$query = "SELECT id, name, quicktake FROM #__reviews WHERE published = '1' ORDER BY review_date DESC";
$db->setQuery( $query, 0, $items );
$rows = $db->loadObjectList();
foreach ($rows as &$row)
{
$row->link = modReviewsHelper::makeReviewLink($row);
}
return $rows;
}
function...
