正如你所看到的，有item_name1和item_name2如何获取这些项目的值，例如我已经支付了10项？这可能是从item_name1到item_name10

我通过我的PHP代码生成了这些项目编号，比如

<?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;
?>

如果你看一下示例paypal响应，有mc_gross_1，mc_gross_2 ... tax1，tax2等等。那么我如何获得那些增加数字并将其保存在数据库中的值呢？

Answer 1

你也有[num_cart_items] = 2。所以只做一个循环...

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);
}

如何在paypal IPN中获取item_number？
