How to use PHP Developer Mall to realize the membership level point redemption function

With the rapid development of e-commerce, mall websites have become one of the main channels for people to purchase goods and services. In order to attract more consumers and increase user stickiness, the mall needs to provide some special functions and services. One of the common features is the membership level point redemption function. This article will introduce how to use the PHP Developer City website to realize the membership level point redemption function.

First, we need to create a database table to store membership level and points information. Suppose we need to store the member's ID, name, level and points. In the MySQL database, create a table named members and add the following fields:

id: Member ID, set it as the primary key, And set up automatic growth
name: Member name, set to VARCHAR type, length is 50
level: Member level, set to INT type
points: Member points, set to INT type

Next, we need to create a script in PHP that connects to the database. First, we need to create a file named config.php in the root directory of the mall website to store the configuration information of the database connection. In config.php, add the following code:

<?php
$db_host = 'localhost';
$db_username = 'username';
$db_password = 'password';
$db_name = 'database_name';

$conn = mysqli_connect($db_host, $db_username, $db_password, $db_name);

if (!$conn) {
    die('数据库连接失败：' . mysqli_connect_error());
}
?>

Copy after login

Note: username, password and database_name need to be Replace with your actual database username, password, and database name.

Next, we need to write a PHP script to handle the logic of membership level point redemption. Create a file named redeem_points.php in the root directory of the mall website and add the following code:

<?php
session_start();
require 'config.php';

// 处理会员等级积分兑换的逻辑
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    $member_id = $_SESSION['member_id'];
    $points = $_POST['points'];
    $level = $_POST['level'];

    // 更新会员积分和等级
    $sql = "UPDATE members SET points = points - $points, level = $level WHERE id = $member_id";
    $result = mysqli_query($conn, $sql);

    if ($result) {
        echo "会员等级积分兑换成功！";
    } else {
        echo "会员等级积分兑换失败：" . mysqli_error($conn);
    }
}
?>

Copy after login

In the above code, we first passsession_start()The function starts the session to obtain the member ID in subsequent logic. Then, we obtain the points and level information submitted by the user from the $_POST array, and use the UPDATE statement to update the member points and level information in the database.

Finally, we need to create a page in the mall website to display the interface for redeeming membership level points. Create a file named redeem_points.php in the root directory of the mall website and add the following code:

<?php require 'config.php'; ?>

<!DOCTYPE html>
<html>
<head>
    <title>会员等级积分兑换</title>
</head>
<body>
    <h1>会员等级积分兑换</h1>
    <form method="POST" action="redeem_points.php">
        <label for="points">积分：</label>
        <input type="text" id="points" name="points"><br>

        <label for="level">等级：</label>
        <input type="text" id="level" name="level"><br>

        <input type="submit" value="兑换">
    </form>
</body>
</html>

Copy after login

In the above code, we first passrequire 'config. The php' statement introduces the configuration file of the database connection. We then create a form that allows members to enter the points and tiers they want to redeem. When a member clicks the "Redeem" button, the form will be submitted to the redeem_points.php script for processing.

Through the above steps, we have successfully implemented the membership level point redemption function. Members of the mall website can complete the points redemption operation by filling in the points and level form. This can encourage members to consume and increase user stickiness, while also bringing greater benefits to the mall.
