edit prestashop hook

this prestashop hook give me only the first result even if the customer buy 2 items, public function hookDisplayAdminOrder($params) { $id_order = (int) Tools::getValue('id_order'); // Get all products associated with the order $sql = 'SELECT product_id FROM '._DB_PREFIX_.'order_detail WHERE id_order = '.(int) $id_order; $result = Db::getInstance(_PS_USE_SQL_SLAVE_)->executeS($sql); $product_ids = array(); foreach ($result as $row) { $product_ids[] = $row['product_id']; } // Iterate over all products foreach ($product_ids as $product_id) { // Obter informações do produto $sql_product = 'SELECT url FROM '._DB_PREFIX_.'scrape_ali_info WHERE id_product='.(int) $product_id; $product_data = Db::getInstance(_PS_USE_SQL_SLAVE_)->getRow($sql_product); // Do something with product information $this->context->smarty->assign(array( 'id_produto' => $product_id, 'ali_url' => $product_data['url'], 'id_order' => $id_order )); // Here you can make decisions about what to do with the data, or just display it echo $this->display(__FILE__, 'views/templates/admin/[login to view URL]'); } } when I try to do echo inside, its not working. someone can only edit this code to make it work.
