Analysis of mall after-sales service function developed using PHP

Mall after-sales service is a very important part of the e-commerce platform. It is responsible for handling after-sales issues such as refunds, returns, and exchanges after users purchase goods. . In order to improve user experience and merchant operation efficiency, we can use PHP language to develop the after-sales service function of the mall.

1. Database design
First of all, we need to design a database to store after-sales service-related data. Suppose we have the following tables:

1. users table: stores user information, including user ID, user name, mobile phone number, etc.
2. orders table: stores order information, including order ID, user ID, product ID, order time, etc.
3. aftersales table: stores after-sales service information, including after-sales ID, order ID, after-sales type, application time, etc.
4. aftersales_items table: stores specific product information for after-sales services, including after-sales ID, product ID, product quantity, etc.

2. Page design
Next, we need to design a page to display after-sales service related information. The following is a sample code for a simple after-sales service page:

<?php
// 连接数据库
$conn = new mysqli('localhost', 'username', 'password', 'database');

// 获取用户ID
$user_id = $_SESSION['user_id'];

// 查询用户的售后服务信息
$query = "SELECT * FROM aftersales WHERE user_id = $user_id";
$result = $conn->query($query);

// 循环获取售后服务信息并展示在页面上
while ($row = $result->fetch_assoc()) {
    $aftersales_id = $row['aftersales_id'];
    $order_id = $row['order_id'];
    $aftersales_type = $row['aftersales_type'];
    $apply_time = $row['apply_time'];

    echo '<div>';
    echo '售后ID：' . $aftersales_id . '<br>';
    echo '订单ID：' . $order_id . '<br>';
    echo '售后类型：' . $aftersales_type . '<br>';
    echo '申请时间：' . $apply_time . '<br>';
    echo '</div>';
}
?>

3. Function implementation
Next, we need to implement some common after-sales service functions, such as submitting after-sales applications, processing after-sales applications, etc. The following is a sample code for implementing a simple after-sales service function:

<?php
// 连接数据库
$conn = new mysqli('localhost', 'username', 'password', 'database');

// 提交售后申请
function submit_aftersales($order_id, $aftersales_type) {
    $user_id = $_SESSION['user_id'];
    $apply_time = date('Y-m-d H:i:s');
    
    // 插入售后服务信息到数据库
    $query = "INSERT INTO aftersales (order_id, user_id, aftersales_type, apply_time) 
              VALUES ($order_id, $user_id, '$aftersales_type', '$apply_time')";
    $conn->query($query);
}

// 处理售后申请
function process_aftersales($aftersales_id, $process_status) {
    // 更新售后服务信息，设置处理状态
    $query = "UPDATE aftersales SET process_status = '$process_status' WHERE aftersales_id = $aftersales_id";
    $conn->query($query);
}

// 调用提交售后申请函数
submit_aftersales(1, 'return');

// 调用处理售后申请函数
process_aftersales(1, 'completed');
?>

The above code is a simple example of a mall after-sales service function, which you can modify and expand according to specific needs. The mall after-sales service function developed using PHP language can help us better manage after-sales affairs and improve user experience and merchant operation efficiency.
