Question

我在生产服务器中遇到了一个非常奇怪的问题。我正在开发MLM项目，用户可以从他们的个人文件柜中订购产品。当他们刷新（更改所选项目的数量）在购物车页面上时出现问题，如果用户更改数量并刷新购物车价格计算错误，但一切都在我的本地机器上正常工作：

以下是代码的简化版本：

QuantityType

....
public function buildForm(FormBuilderInterface $builder, array $options)
{
    $productLineItems = $options['productLineItems'];

    /** @var ProductLineItem $productLineItem */
    foreach ($productLineItems as $productLineItem) {
        $builder
            ->add(
                $builder
                    ->create($productLineItem->getId(), 'form', [
                        'data' => $productLineItem
                    ])
                    ->add('quantity', 'number', [
                        'data' => $productLineItem->getQuantity()
                    ])
                    ->add('remove', 'submit')
            );
    }
}

CartType

...
public function buildForm(FormBuilderInterface $builder, array $options)
{

    $builder
        ->add('productLineItems', 'sl_core_quantity', [
            'productLineItems' => $options['productLineItems']
        ])
        ->add('update', 'submit')
    ;

    ...
}

控制器：

$partner = $this->getEntityManager()->getRepository('SLCoreBundle:User')->find($partnerId);

/** @var BaseOrderManager $orderManager */
$orderManager = $this->get('sl.core.manager.base_order');

$order = $orderManager->getOrderByUserAndStatus($partner, BaseOrder::STATUS_CART, BaseOrderManager::TYPE_PARTNER);

$cartProductLineItems = $orderManager->getProductLineItemsByOrder($order);

$cartForm = null;
if (null != $cartProductLineItems) {
    $cartForm = $this->createForm('sl_core_cart', null, [
        'productLineItems' => $cartProductLineItems,
        'user' => $partner,
        'action' => $this->generateUrl('ACTION', ['partnerId' => $partnerId])
    ]);

    $cartForm->handleRequest($request);
    if ($cartForm->isValid()) {

        $clickedButton = $cartForm->getClickedButton();

        if ($clickedButton->getName() == 'remove') {
            $selectedItem = $clickedButton->getParent()->getData();

            $label = $selectedItem->getLabel();

            $orderManager->removeItemFromOrder($order, $selectedItem);

            $this->get('session')->getFlashBag()->add('notice', $label . ' removed from your cart.');
        }
        else if ($clickedButton->getName() == 'update') {
            $submittedData = $cartForm->getData();

            $submittedProductLineItems = $submittedData['productLineItems'];

            $orderManager->updateProductLineItems($order, $submittedProductLineItems);

            $this->get('session')->getFlashBag()->add('notice', 'Shopping cart updated.');
        }
        else if ($clickedButton->getName() == 'checkout') {
            $submittedData = $cartForm->getData();
            $submittedProductLineItems = $submittedData['productLineItems'];
            $orderManager->updateProductLineItems($order, $submittedProductLineItems);

            return $this->redirect($this->generateUrl('ACTION', ['partnerId' => $partnerId]));
        }

        return $this->redirect($this->generateUrl('ACTOPN', ['partnerId' => $partnerId]));
    }
}

return $this->render('@SLWeb/BackOffice/Order/create_partner_order.cart.html.twig', [
    'currency_code' => $request->cookies->get('sl_currency_code'),
    'cart_form' => null != $cartForm ? $cartForm->createView() : null,
    'cart_product_line_items' => $cartProductLineItems,
    'order' => $order,
    'partner' => $partner
]);

BaseOrderManager

public function updateProductLineItems(BaseOrder $order, array $lineItems)
    {
        $quantityChanged = false;

        $orderLineItems = $this->entityManager->getRepository('SLCoreBundle:ProductLineItem')->fetchAllUnchangedQuantityByOrder($order);

        /**
         * @var int $key
         * @var ProductLineItem $submittedLineItem
         */
        foreach (array_values($lineItems) as $key => $submittedLineItem) {

            $submittedLineItemQuantity = $submittedLineItem->getQuantity();
            $orderLineItemQuantity = $orderLineItems[$key]['quantity'];

            if ($submittedLineItemQuantity == $orderLineItemQuantity) {
                continue;
            }

            ....

            $productLineItemPrices = $submittedLineItem->getLineItemPrices();
            /** @var LineItemPrice $productLineItemPrice */
            foreach ($productLineItemPrices as $productLineItemPrice) {
                $priceValue = $productLineItemPrice->getValue();

                $productLineItemPrice->setTotalPrice($priceValue * $submittedLineItem->getQuantity());

                if ($submittedLineItemQuantity < $orderLineItemQuantity) {
                    $quantityDiff = $orderLineItemQuantity - $submittedLineItemQuantity;
                    $this->updateOrderPrice($order, $productLineItemPrice, $quantityDiff, self::QUANTITY_DECREASED);

                    ....
                }
                else {
                    $quantityDiff = $submittedLineItemQuantity - $orderLineItemQuantity;
                    $this->updateOrderPrice($order, $productLineItemPrice, $quantityDiff, self::QUANTITY_INCREASED);

                    ....
                }
            }

            $quantityChanged = true;
        }

        if ($quantityChanged) {
            $this->entityManager->flush();

    }



public function updateOrderPrice(BaseOrder $order, LineItemPrice $lineItemPrice, $quantity, $operation = self::QUANTITY_INCREASED)
    {

    }

生产服务器屏幕（错误）： enter image description here 更糟糕的是（下次刷新后）

enter image description here

本地版本（正确）： enter image description here

我甚至不明白为什么相同版本的代码工作方式如此不同，项目版本是相同的，php，nginx，mysql版本和配置是相同的，禁用缓存没有帮助，在哪里挖？ / p>

可能是我以某种方式解决了问题，但我完全不了解问题和解决方案：）

在我的fetchAllUnchangedQuantityByOrder($order)方法中，我正在直接查询数据库以获取未更改的行，就像这样（因为，我的getters在表单绑定后返回更改的表单值）：

public function fetchAllUnchangedQuantityByOrder(BaseOrder $order)
{
    $orderId = $order->getId();

    $connection = $this->getEntityManager()->getConnection()->prepare('
        SELECT li.quantity
        FROM sl_product_line_item AS li
        INNER JOIN
        sl_base_line_item AS bli ON li.id = bli.id
        WHERE bli.order_id = :order_id
        ORDER BY bli.created_at ASC
    ');

    $connection->bindParam(':order_id', $orderId, \PDO::PARAM_INT);
    $connection->execute();

    return $connection->fetchAll();
}

我认为这是问题，有时它会返回错误的价值，我不明白为什么......

我改变了这一行，问题就消失了。

...

$orderLineItem = $this->entityManager->getUnitOfWork()->getOriginalEntityData($submittedLineItem);

if ($submittedLineItemQuantity == $orderLineItem['quantity']) {
    continue;
}

...
