我想将product.available_date添加到Prestashop 1.6中的购物车中。
我在shopping-cart-product-line-tpl中添加了以下行
{if isset($product.available_date) && $product.available_date > $smarty.now|date_format:'%Y-%m-%d'}
<span id="availability_date_label">{l s='Availability date:'}</span>
<span id="availability_date_value">
{if Validate::isDate($product.available_date)}
{dateFormat date=$product.available_date full=false}
{/if}
</span>
但我发现在Cart.php中没有设置available_date
我在cart.php中找到了以下功能
公共函数getProducts（$ refresh = false，$ id_product = false，$ id_country = null）
我认为用于收集产品数据，它有一个sql-＆gt;选择如下：
// Build query
$sql = new DbQuery();
// Build SELECT
$sql->select('cp.`id_product_attribute`, cp.`id_product`, cp.`quantity` AS cart_quantity, cp.id_shop, pl.`name`, p.`is_virtual`,
pl.`description_short`, pl.`available_now`, pl.`available_later`, **(added p.`available_date` here)**,product_shop.`id_category_default`, p.`id_supplier`,
p.`id_manufacturer`, product_shop.`on_sale`, product_shop.`ecotax`, product_shop.`additional_shipping_cost`,

product_shop.advanced_stock_management, ps.product_supplier_reference supplier_reference');

我尝试在查询中添加p.available_date并获取日期，但是如果产品有组合则不行。然后它在两种组合上添加了相同的日期。
任何人都知道如何让它适用于组合？
答案 0 :(得分：0)
以上查询将通过将cart表与产品，类别和制造商表相关联来获取数据。上述查询中没有联接组合。但是您已经注意到系统正在从上面的查询中获取每个产品的 id_product_attribute ，如果组合功能在存储中处于活动状态，那么系统已经具有获取组合数据的条件，如下所示：
New-PSDrive -Name "X" -PSProvider FileSystem -Root "\\192.168.0.1\hde_path" -Persist
要获取组合可用日期，只需在选择查询中添加可用日期列，如下面的代码所示：
if (Combination::isFeatureActive()) {
$sql->select('
product_attribute_shop.`price` AS price_attribute, product_attribute_shop.`ecotax` AS ecotax_attr,
IF (IFNULL(pa.`reference`, \'\') = \'\', p.`reference`, pa.`reference`) AS reference,
(p.`weight`+ pa.`weight`) weight_attribute,
IF (IFNULL(pa.`ean13`, \'\') = \'\', p.`ean13`, pa.`ean13`) AS ean13,
IF (IFNULL(pa.`isbn`, \'\') = \'\', p.`isbn`, pa.`isbn`) AS isbn,
IF (IFNULL(pa.`upc`, \'\') = \'\', p.`upc`, pa.`upc`) AS upc,
IFNULL(product_attribute_shop.`minimal_quantity`, product_shop.`minimal_quantity`) as minimal_quantity,
IF(product_attribute_shop.wholesale_price > 0, product_attribute_shop.wholesale_price, product_shop.`wholesale_price`) wholesale_price
');
$sql->leftJoin('product_attribute', 'pa', 'pa.`id_product_attribute` = cp.`id_product_attribute`');
$sql->leftJoin('product_attribute_shop', 'product_attribute_shop', '(product_attribute_shop.`id_shop` = cp.`id_shop` AND product_attribute_shop.`id_product_attribute` = pa.`id_product_attribute`)');
} else {
$sql->select(
'p.`reference` AS reference, p.`ean13`, p.`isbn`,
p.`upc` AS upc, product_shop.`minimal_quantity` AS minimal_quantity, product_shop.`wholesale_price` wholesale_price'
);
}
