Question

应用折扣后我需要进行运费计算

例如。
购物车总额：65 $
免费送货开始：65 $
折扣：5％

折扣后，价格降至65 $以下，并且仍然免费送货我需要它来计算发货之前的折扣

Answer 1

首先按运营商设置范围（0-65：X欧元，高于65：0欧元）

重写Cart.php类

Rewrite function getPackageShippingCost

行后

// Order total in default currency without fees
$order_total = $this->getOrderTotal(true, Cart::BOTH_WITHOUT_SHIPPING, $product_list);

添加此

//Recalcul total pour panier et livraison gratuite 
$listeDiscounts = $this->getCartRules();        
$total_discounts = 0;
if (is_array($listeDiscounts)) {
    if (isset($listeDiscounts[0]['value_real']))
        $total_discounts = $listeDiscounts[0]['value_real'];            
}
$price_to_apply_shipment = floatval($order_total) - floatval($total_discounts);

替换

//$check_delivery_price_by_price = Carrier::checkDeliveryPriceByPrice($row['id_carrier'], $total_order, (int)$id_zone, (int)$this->id_currency);
by                    
$check_delivery_price_by_price = Carrier::checkDeliveryPriceByPrice($row['id_carrier'], $price_to_apply_shipment, (int)$id_zone, (int)$this->id_currency);

然后

//$shipping_cost += $carrier->getDeliveryPriceByPrice($the_total_price, $id_zone, (int)$this->id_currency);
By 
$shipping_cost += $carrier->getDeliveryPriceByPrice($price_to_apply_shipment, $id_zone, (int)$this->id_currency);
