so I am have a query that finds all the products that are "on_sale" = 1 but the problem is that in smarty href="{$product.link}" return nothing
here is the SQL query
public static function getOnSaleProducts($id_lang, $page_number = 0, $nb_products = 10,
$count = false, $order_by = null, $order_way = null, Context $context = null)
{
if (!$context)
$context = Context::getContext();
$front = true;
if (!in_array($context->controller->controller_type, array('front', 'modulefront')))
$front = false;
if ($page_number < 0) $page_number = 0;
if ($nb_products < 1) $nb_products = 10;
if (empty($order_by) || $order_by == 'position') $order_by = 'date_add';
if (empty($order_way)) $order_way = 'DESC';
if ($order_by == 'id_product' || $order_by == 'price' || $order_by == 'date_add' || $order_by == 'date_upd')
$order_by_prefix = 'p';
else if ($order_by == 'name')
$order_by_prefix = 'pl';
if (!Validate::isOrderBy($order_by) || !Validate::isOrderWay($order_way))
die(Tools::displayError());
$groups = FrontController::getCurrentCustomerGroups();
$sql_groups = (count($groups) ? 'IN ('.implode(',', $groups).')' : '= 1');
if (strpos($order_by, '.') > 0)
{
$order_by = explode('.', $order_by);
$order_by_prefix = $order_by[0];
$order_by = $order_by[1];
}
if ($count)
{
$sql = 'SELECT COUNT(p.`id_product`) AS nb

return (int)Db::getInstance(_PS_USE_SQL_SLAVE_)->getValue($sql);
}
$sql = new DbQuery();

if (!$result)
return false;
$products_ids = array();
foreach ($result as $row)
$products_ids[] = $row['id_product'];
// Thus you can avoid one query per product, because there will be only one query for all the products of the cart
Product::cacheFrontFeatures($products_ids, $id_lang);
return Product::getProductsProperties((int)$id_lang, $result);
}
the query finds all the product I need but the products do not have links.
