require_once HELPERS_PATH.'/helper.php';

class JBusinessDirectoryModelPackages extends JModelList {
public function __construct($config = array()) {
if (empty($config['filter_fields'])) {
$config['filter_fields'] = array(
'id', 'p.id',
'name', 'p.name',
'price', 'p.price',
"special_price", "p.special_price",
"days", "p.days",
"special_from_date", "p.special_from_date",
"special_to_date", "p.special_to_date",
"status", "p.status",
'ordering', 'p.ordering',
"popular", "p.popular"
);
}

parent::__construct($config);
}
