How to use PHP Developer City to implement the order payment timeout cancellation function

In the development of e-commerce, order payment is a crucial link. However, due to various reasons, buyers often do not complete payment immediately after placing an order. In order to protect the rights and interests of merchants, it is necessary to limit the payment time within a certain period of time and cancel the order after the payment times out. This article will introduce how to use the PHP Developer City to implement the order payment timeout cancellation function.

First of all, in order to implement the order payment timeout cancellation function, we need to save the creation time and payment status of the order in the database. Create an order table, including fields such as order number, creation time, payment time, order status, etc.

Next, when the user places an order, the creation time and order status (unpaid) of the order are inserted into the order table. At the same time, in order to easily check whether the order has timed out, a field can be added to the order table to save the payment timeout time. For example, assuming the order timeout is 30 minutes, you can add a field named "expire_time" to the order table to save the payment timeout (order creation time 30 minutes).

After the user completes the payment, update the order's payment time and order status (paid) to the order table.

In order to detect payment timeout, you can set up a scheduled task in the background management system to check the order status and payment time in the order table every minute. By comparing the current time with the payment time of the order, you can determine whether the order has timed out. If the order times out, the order status is updated to canceled and a corresponding notification is sent to the buyer.

The following is a simple PHP code example:

// 检查订单是否超时并取消
function checkOrderTimeout() {
    $now = date("Y-m-d H:i:s");
    $expiredOrders = getExpiredOrders($now);

    foreach ($expiredOrders as $order) {
        cancelOrder($order['order_id']);
        sendNotification($order['user_id'], '您的订单已超时取消');
    }
}

// 获取超时订单
function getExpiredOrders($now) {
    $sql = "SELECT * FROM orders WHERE order_status='未支付' AND expire_time < '$now'";
    // 执行查询操作
    // ...

    // 返回结果集
    // ...
}

// 取消订单
function cancelOrder($orderId) {
    $sql = "UPDATE orders SET order_status='已取消' WHERE order_id='$orderId'";
    // 执行更新操作
    // ...
}

// 发送通知
function sendNotification($userId, $message) {
    // 发送通知给用户
    // ...
}

// 每分钟执行一次检查订单超时任务
// cron: * * * * * /usr/bin/php /path/to/check_order_timeout.php >/dev/null 2>&1
checkOrderTimeout();

By setting a scheduled task and executing the task of checking the order timeout every minute, the order payment timeout cancellation function can be implemented.

To sum up, by using the PHP Developer City to implement the order payment timeout cancellation function, the rights and interests of merchants can be effectively protected. By setting up scheduled tasks to check order timeouts, cancel overtime orders and notify buyers, you can improve user experience and optimize the order management process.
