Paypal快速結帳結帳後的多個項目

Question

我目前正在實施一個PayPal快速結帳，我有多個項目進入訂單。這些項目已成功進入Pay​​Pal並單獨顯示在發票上。一旦客戶返回到我的網站，客戶將通過一個處理頁面返回，該頁面將這些項目放入數據庫中，但不是單個項目的單獨價格被列出，而是隻收到一個項目和總價格。

if($_POST) //Post Data received from product list page. 
{ 
//Other important variables like tax, shipping cost 
$TotalTaxAmount  = 0.00; //Sum of tax for all items in this order. 
$HandalingCost  = 0.00; //Handling cost for this order. 
$InsuranceCost  = 0.00; //shipping insurance cost for this order. 
$ShippinDiscount = 0.00; //Shipping discount for this order. Specify this as negative number. 
$ShippinCost  = 0.00; //Although you may change the value later, try to pass in a shipping amount that is reasonably accurate. 

//we need 4 variables from product page Item Name, Item Price, Item Number and Item Quantity. 
//Please Note : People can manipulate hidden field amounts in form, 
//In practical world you must fetch actual price from database using item id.

這是Paypal發送的信息數組。

我的代碼結束了GetExpressCheckout要求

foreach($paypal_product['items'] as $key=>$p_item){ 
        $buyerName = urldecode($httpParsedResponseAr["FIRSTNAME"]).' '.urldecode($httpParsedResponseAr["LASTNAME"]); 
        $buyerEmail = urldecode($httpParsedResponseAr["EMAIL"]);       

        $insert_row = $db->query("INSERT INTO BuyerTable 
        (BuyerName,BuyerEmail,TransactionID,ItemName,ItemNumber,ItemAmount,ItemQTY) 
        VALUES ('$buyerName','$buyerEmail','".$transactionID."','".$p_item['itm_name']."','".$p_item['itm_code']."','".$p_item['itm_price']."','".$p_item['itm_qty']."')"); 
        $insert_row->execute(); 
        } 

所有的產品現在都用其正確的價值和數量分別列出創建用於插入foreach循環。
