I added p.`condition` at the end to sql query in getProducts method like this:
$sql->select('cp.`id_product_attribute`, cp.`id_product`, cp.`quantity` AS cart_quantity, cp.id_shop, cp.`id_customization`, pl.`name`, p.`is_virtual`, pl.`description_short`, pl.`available_now`, pl.`available_later`, product_shop.`id_category_default`, p.`id_supplier`, p.`id_manufacturer`, m.`name` AS manufacturer_name, product_shop.`on_sale`, product_shop.`ecotax`, product_shop.`additional_shipping_cost`, product_shop.`available_for_order`, product_shop.`show_price`, product_shop.`price`, product_shop.`active`, product_shop.`unity`, product_shop.`unit_price_ratio`, stock.`quantity` AS quantity_available, p.`width`, p.`height`, p.`depth`, stock.`out_of_stock`, p.`weight`, p.`available_date`, p.`date_add`, p.`date_upd`, IFNULL(stock.quantity, 0) as quantity, pl.`link_rewrite`, cl.`link_rewrite` AS category, CONCAT(LPAD(cp.`id_product`, 10, 0), LPAD(IFNULL(cp.`id_product_attribute`, 0), 10, 0), IFNULL(cp.`id_address_delivery`, 0), IFNULL(cp.`id_customization`, 0)) AS unique_id, cp.id_address_delivery, product_shop.advanced_stock_management, ps.product_supplier_reference supplier_reference, p.`condition`');
Yet when i run this code in cart-detailed-product-line.tpl file, nothing shows in the console, even i added the condition ( New ) to all the products in the cart from the BO!
<script> console.log('{$product.condition.label}'); </script>
