Magento的sales_order_place_before $觀察者getevent空

Question

我有以下觀察員方法：

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事件是空的，我也試了getQuote這也爲空。我需要從活動中獲取購物車的內容，以查看其創建的內容。有任何想法嗎？

Answer 1

按如，sales_order_place_before事件它只提供訂單對象，使提供的報價對象直接。

你想從這個事件quote object那麼你需要得到quote id從Order object然後使用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

這個事件爲您提供了一個完整的order實例，而不是一個cart實例，您可以查看Mage_Sales_Model_Order類（第1113行）。

如果你想獲取cart然後執行：

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