Question

我有以下观察者方法：

public function ModifyOrderECC(Varien_Event_Observer $observer)
{
    //sales_order_place_before
    Mage::log('ECC!! = ModifyOrderECC has been called successfully - event/array-5', null, 'mylog.log');
    $cart = $observer->getEvent()->getCart();
    try{
        if($cart != NULL)
        {
            Mage::log('$cart contains data!', null, 'mylog.log');

            foreach ($cart->getItems() as $item) {
                $getID = $item->getProduct()->getId();
                $productName = $item->getProduct()->getName();
                $productPrice = $item->getProduct()->getPrice();
                $quantity = (string)$item->getProduct()->getQtyOrdered();

                Mage::log('ID: '.$getID, null, 'mylog.log');
                Mage::log('Name: '.$productName, null, 'mylog.log');
                Mage::log('Price: '.$productPrice, null, 'mylog.log');
                Mage::log('Qty: '.$quantity, null, 'mylog.log');
            }
        }else
        {
            Mage::log('sorry Cart is null :(', null, 'mylog.log');
        }

    }catch(Exception $e)
    {
        Mage::log($e->getMessage());
        Mage::log('error = '.$e->getMessage(), null, 'mylog.log');
    }

}

但是getCart事件是null，我也尝试过getquote，它也是null。我需要从事件中获取购物车的内容，以查看其创建的内容。有什么想法吗？

Answer 1

根据 sales_order_place_before 事件， 仅提供订单对象并启用直接提供报价对象 。

您希望此活动中出现quote object，然后您需要从quote id获取Order object，然后使用quote id you can get quote object。

 public function ModifyOrderECC(Varien_Event_Observer $observer)
    {
        //sales_order_place_before


        $QuoteID=$observer->getEvent()->getOrder()->getQuoteId();
    $quoteObject=Mage::getModel('sales/quote')->load($QuoteID);
...
    }

Answer 2

通过查看order类（第1113行），您可以看到此事件为您提供了整个cart实例，而不是Mage_Sales_Model_Order实例。

如果您想检索cart，请执行：

$cart = Mage::getSingleton('checkout/cart')->getQuote();
foreach ($cart->getAllItems() as $item) {
    // do something
}

Magento sales_order_place_before $ observer getevent null
