如何获取paypal IPN中的item_number？

这里是从PayPal的一个样本响应后，我使用沙盒如何获取paypal IPN中的item_number？

Array

    [address_city] => San Jose 
    [address_country] => United States 
    [address_country_code] => US 
    [address_name] => Test User

    [item_number1] => 2 
    [item_number2] => 1 
    [last_name] => User 
    [mc_currency] => USD 
    [mc_fee] => 0.79 
    [mc_gross] => 17.00 
    [mc_gross_1] => 7.00 
    [mc_gross_2] => 10.00 
    [mc_handling] => 0.00

    [mc_shipping1] => 2.00 
    [mc_shipping2] => 0.00 
    [merchant_return_link] => click here 
    [notify_version] => 3.4 
    [num_cart_items] => 2

    [tax2] => 0.00 
    [test_ipn] => 1 
    [transaction_subject] => Shopping CartiPod TouchGiant Hamburger, the world's biggest 
    [txn_id] => 4BK63214AG342352Y

    [verify_sign] => A0Jk1FY.7aHd-VRk44a4grBP7kE.A0Azn34Obs6QiSJKuCvAWSWyItkH 
)

你可以看到，有item_name1和item_name2怎么去完成支付车的这些物品的价值，让我们说，例如，我有付10件物品？这将是像item_name1到item_name10

我生成项目的编号是通过我的PHP代码，这样

<?php 
    $i = 1; 
    foreach($_SESSION['cart'] as $id => $qty): 
    $product = find_product($id); 
?> 

<input type="hidden" name="item_name_<?php echo $i; ?>" value="<?php echo $product['ProductDescription']; ?>"> 
<input type="hidden" name="item_number_<?php echo $i; ?>" value="<?php echo $product['ProductID']; ?>"> 
<input type="hidden" name="amount_<?php echo $i; ?>" value="<?php echo $product['ProductOverridePrice']; ?>"> 
<input type="hidden" name="quantity_<?php echo $i; ?>" value="<?php echo $qty; ?>"> 

<?php 
    $i++; 
    endforeach; 
?>

，如果你看一下样品贝宝的响应，有mc_gross_1，mc_gross_2 ... tax1，tax2之类的..所以我怎样才能得到那些增加数字的值并将其保存在数据库中？

不过你也有[num_cart_items] = 2。所以只是做一个循环...

for ($i = 1; $i <= $_POST['num_cart_items']; $i++) { 
    $name = $_POST['item_name' . $i]; 
    $number = $_POST['item_number' . $i]; 
    $quantity = $_POST['quantity' . $i]; 
    //etc... 

    $query = "INSERT INTO payments (product_name, product_id, product_quantity) 
      VALUES ('" . mysql_real_escape_string($name) . "', '" . mysql_real_escape_string($number) . "', '" . mysql_real_escape_string($quantity) . "')"; 
    mysql_query($query); 
}

一个小小的警告：在'num_cart_items'参数不是由PayPal的IPN模拟器提供。只是想我会提到，以防有人使用它进行测试。 – 2013-08-23 20:27:47
