Question

我目前正在开发一家网上商店。对于本网站，我没有将任何购物车历史记录存储到我的数据库中，因此我没有关于客户订单的任何详细信息。我计划在客户付款后立即获取订单详情。

我现在的问题是我的产品作为数组发送到paypal，每个交易都保存到我的数据库表字段中，如下所示：

20-1,21-1

20和21是产品ID，紧邻它是数量。

我需要知道，我是否可以仅从paypal IPN检索订单而无需创建特定数据库来存储客户的订单？

我真的需要你的帮助吗

$product_id_string = $_POST['custom'];
$product_id_string = rtrim($product_id_string, ","); // remove last comma
// Explode the string, make it an array, then query all the prices out, add them up, and make sure they match the payment_gross amount
$id_str_array = explode(",", $product_id_string); // Uses Comma(,) as delimiter(break point)
$fullAmount = 0;
foreach ($id_str_array as $key => $value) {

    $id_quantity_pair = explode("-", $value); // Uses Hyphen(-) as delimiter to separate product ID from its quantity
    $product_id = $id_quantity_pair[0]; // Get the product ID
    $product_quantity = $id_quantity_pair[1]; // Get the quantity
