Discussion on the implementation of the mall delivery progress monitoring function developed by PHP

In the modern e-commerce industry, timely and accurate understanding of the delivery progress of goods is crucial for both merchants and buyers. In order to meet this demand, we can develop a reliable mall delivery progress monitoring function through PHP.

This article will discuss how to use PHP and related libraries and technologies to achieve this functionality. We will step by step introduce the entire process of shipping from the mall and give corresponding code examples.

1. Determine the database structure

First, we need to design the database structure to store order information and shipping status. We can create a table called "orders" with the following fields: order_id (order ID), customer_name (customer name), status (shipping status), and update_time (update time).

Use the following SQL code to create a table:

CREATE TABLE orders (
  order_id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
  customer_name VARCHAR(30) NOT NULL,
  status VARCHAR(10) NOT NULL,
  update_time TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
)

2. Create order

In the mall website, when a customer places an order, we need to The information is saved to the database. You can use the following code to create a file called "create_order.php" to handle the order creation logic:

connect_error) {
    die("连接数据库失败：".$conn->connect_error);
}

// 获取顾客姓名
$customer_name = $_POST['customer_name'];

// 创建订单并插入数据库
$sql = "INSERT INTO orders (customer_name, status) VALUES ('".$customer_name."', '待发货')";

if ($conn->query($sql) === true) {
    echo "订单创建成功";
} else {
    echo "订单创建失败".$conn->error;
}

// 关闭数据库连接
$conn->close();
?>

3. Update shipping status

Once the merchant is ready to ship , they can notify buyers by updating order shipping status. You can use the following code to create a file named "update_status.php" to handle the logic of updating the shipping status:

connect_error) {
    die("连接数据库失败：".$conn->connect_error);
}

// 获取订单ID和新的状态
$order_id = $_POST['order_id'];
$status = $_POST['status'];

// 更新发货状态
$sql = "UPDATE orders SET status='".$status."' WHERE order_id=".$order_id;

if ($conn->query($sql) === true) {
    echo "状态更新成功";
} else {
    echo "状态更新失败".$conn->error;
}

// 关闭数据库连接
$conn->close();
?>

4. Monitor the shipping progress

Buyers can Understand the delivery status of your order in real time by monitoring the delivery progress page. You can use the following code to create a file called "track_order.php" that uses Ajax to get the latest shipping status:

订单发货进度：

5. Get the latest shipping status

Finally, we can use the following code to create a file named "get_status.php", which is used to return the latest shipping status through Ajax:

connect_error) {
    die("连接数据库失败：".$conn->connect_error);
}

// 查询最新状态
$sql = "SELECT status FROM orders ORDER BY update_time DESC LIMIT 1";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    $row = $result->fetch_assoc();
    echo $row["status"];
} else {
    echo "暂无更新";
}

// 关闭数据库连接
$conn->close();
?>

With the above code example, we can implement a Basic shopping mall delivery progress monitoring function. Merchants can create orders and update delivery status, and buyers can monitor the delivery progress of orders in real time.

Of course, this is just a simple implementation example, and actual development may involve more complex logic and functions. I hope this article can provide readers with some ideas and guidance for improvement and expansion in actual projects.
