CCNow 服务器响应后无法识别 PHP 会话

Question

我将 CCNow 支付网关与我的自定义 PHP 购物车一起使用。我的代码运行良好，只是当 CCNow 服务器响应我的页面时无法识别购物车会话。

在该响应中，CCNow 发送带有订单状态的订单详细信息，我的代码应该在此阶段保存或更新订单。

我通过直接在浏览器中输入页面来测试该页面，它运行良好。我还通过将订单 ID 存储在日志文件中来确保 CCNow 响应发生。

有什么想法吗？我的代码如下：

<?php
session_start();
include('includes/config.php');
include('includes/db.php');

$status = 0;
$x_status = '';
$x_orderid = '';
$x_orderdate = '';
$key = '12345';

if(isset($_REQUEST['x_status'])){
    $x_status = strtolower($_REQUEST['x_status']);
}

if(isset($_REQUEST['x_orderid'])){
    $x_orderid = $_REQUEST['x_orderid'];
}

if(isset($_REQUEST['x_orderdate'])){
    $x_orderdate = $_REQUEST['x_orderdate'];
}

$str = $x_orderid . '^' . $x_status . '^' . $x_orderdate . '^' . $key;
$hash = md5($str);

if(($x_status == 'pending') || ($x_status == 'test')){
    $status = 1;
}

$order_exists = false;

$sql = "SELECT id FROM orders WHERE method = 'CCNow' and x_orderid = '" . $x_orderid . "' LIMIT 1";
$result = mysql_query($sql);
while ( $value = mysql_fetch_array($result) ){
    $order_exists = true;
}

if($order_exists){ // update order
    $sql = "UPDATE orders SET status = " . $status . " WHERE method = 'CCNow' and x_orderid = '" . $x_orderid . "'";
    $result = mysql_query($sql);
}
else{ // add new order
    if(isset($_SESSION["products"])){
        $customer_id = $_SESSION['customer_id'];
        $net = $_SESSION['cart_net'];
        $shipping_cost = $_SESSION['cart_shipping_cost'];
        $date = date("Y-m-d");
        // save order
        $sql = "INSERT INTO orders(customer_id, date, method, status, net, shipping_cost, x_orderid) ";
        $sql.= "VALUES($customer_id, '$date', 'CCNow', $status, $net, $shipping_cost, '$x_orderid')";
        $result = mysql_query($sql);
        $order_id = mysql_insert_id($GLOBALS['connection']);
        // save order details
        foreach ($_SESSION["products"] as $cart_itm){
            $product_id = $cart_itm["ID"];
            $product_code = $cart_itm["code"];
            $product_qty = $cart_itm["qty"];
            $product_price = $cart_itm["price"];
            $subtotal = ($cart_itm["price"]*$cart_itm["qty"]);
            $sql = "INSERT INTO order_details(order_id, product_id, price, qty, net) ";
            $sql.= "VALUES($order_id, $product_id, $product_price, $product_qty, $subtotal)";
            $result = mysql_query($sql);
        }
        // unset cart sessions and redirect to success page
        unset($_SESSION['cart_net']);
        unset($_SESSION['cart_shipping_cost']);
        unset($_SESSION['products']);
    }
    else{
        file_put_contents('ccnowlog.txt', date('Y-m-d h s i') . 'Not seeing the session!!!', FILE_APPEND);
    }
}

// This is an OK response to CCNow IMPORTANT
echo 'ok';

?>

您的问题是逻辑问题！

您与 CCNow 通信并发送交易。但是服务器 von CCNow 会单独回答您 - 从逻辑上讲，“客户会话”将无法访问。

您必须使用 Order-ID 才能获取数据。另外你可以修改参数。下面是来自插件的一个小示例：

 $data['x_fp_sequence']             = $sessionid
 $data['x_invoice_num']             = $sessionid;

你看，会话 ID 将与 x_fp_sequence 和 x_invoice_num 一起传递。在您的响应脚本上，您必须使用它来获取用户会话。否则，您可以直接从数据库中获取用户数据。
