Magento--修改已存在的订单的运费

遇到一种情况，需要在下单后再由管理员添加订单运费，然后顾客再付款。那么问题来了，如何给订单添加运费呢？下面是一段代码，可以实现该功能：

$orderId = 'your order id';
$order = Mage::getModel('sales/order')->load($orderId);
$baseCurrencyCode = Mage::app()->getStore()->getBaseCurrencyCode();
$currentCurrencyCode = $order->getOrderCurrencyCode();
$shippingAmount = Mage::helper('directory')->currencyConvert($params['shipping']['amount'], $currentCurrencyCode, $baseCurrencyCode);
$notify = isset($params['shipping']['is_customer_notified']) ? true : false;

$order->setBaseGrandTotal($order->getBaseGrandTotal() + $shippingAmount);
$order->settBaseSubtotal($order->getBaseSubtotal() + $shippingAmount); //$order->setBaseSubtotalInvoiced($order->getBaseSubtotalInvoiced() + $shippingAmount); //$order->setBaseTotalInvoiced($order->getBaseTotalInvoiced() + $shippingAmount); //$order->setBaseTotalPaid($order->getBaseTotalPaid() + $shippingAmount); $order->setGrandTotal($order->getGrandTotal() + $shippingAmount); $order->setSubtotal($order->getSubtotal()); //$order->setSubtotalInvoiced($order->getSubtotalInvoiced() + $shippingAmount); //$order->setTotalInvoiced($order->getTotalInvoiced() + $shippingAmount); //$order->setTotalPaid($order->getTotalPaid() + $shippingAmount); $order->setBaseSubtotalInclTax($order->getBaseSubtotalInclTax() + $shippingAmount); $order->setSubtotalInclTax($order->getSubtotalInclTax() + $shippingAmount); $order->setTotalDue($order->getTotalDue() - $order->getShippingAmount() + $shippingAmount);

$order->setShippingAmount($shippingAmount); $order->setBaseShippingAmount($shippingAmount); 
Mage::getModel('wholesale/core')->sendOrderEmail($order, 'wholesale_savers_order_update', $attch = '');
$order->setCarriageConfirmed(1); 
$order->save();

 

上述的代码中，关于Invoice的都是注释掉的，下面分两个情况说一下：

当订单还是pending的时候，如果上面的Invoice代码没有注释掉，那么当你在后台点击生成Invoice的时候，生成的invoice将不会包含你添加的运费的金额。例如订单的金额是1000，后台添加了20块运费，那么在生成invoice的时候，invoice的金额就是1000，不会是1020。只有在添加运费时不设置SubtotalInvoiced等才会是1020.

 

权当备忘。
