Question

在Prestashop的CartRule类中，定义了这个常量：

/* Filters used when retrieving the cart rules applied to a cart of when calculating the value of a reduction */
const FILTER_ACTION_ALL = 1; 
const FILTER_ACTION_SHIPPING = 2;
const FILTER_ACTION_REDUCTION = 3;
const FILTER_ACTION_GIFT = 4;
const FILTER_ACTION_ALL_NOCAP = 5;

有没有人知道在使用FILTER_ACTION_ALL_NOCAP时过滤了什么购物车规则？

谢谢。

它用于部分使用的购物车规则。当您使用getContextualValue()过滤器从CartRule班级调用功能CartRule::FILTER_ACTION_ALL_NOCAP时，它会返回购物车总规则金额，而不仅仅是应当在当前购物车中应用的金额（金额永远不会更高）比产品数量）：

// The reduction cannot exceed the products total, except when we do not want it to be limited (for the partial use calculation)
if ($filter != CartRule::FILTER_ACTION_ALL_NOCAP) {
    $reduction_amount = min($reduction_amount, $this->reduction_tax ? $cart_amount_ti : $cart_amount_te);
}

验证订单时，将检索购物车规则值：

$values = array(
    'tax_incl' => $cart_rule['obj']->getContextualValue(true, $this->context, CartRule::FILTER_ACTION_ALL_NOCAP, $package),
    'tax_excl' => $cart_rule['obj']->getContextualValue(false, $this->context, CartRule::FILTER_ACTION_ALL_NOCAP, $package)
);

如有必要，会生成新的购物车规则。

在Prestashop CartRule类中常量FILTER_ACTION_ALL_NOCAP的含义是什么？
