How to use PHP to develop mall functions: build membership points and level system

Introduction:
In modern e-commerce, a successful mall function not only needs to have product display and purchase functions, but also The improvement of user experience and user loyalty needs to be taken into consideration. The membership points and level system is an effective way to motivate users to purchase and enhance user loyalty. This article will introduce how to use PHP to develop a mall function and build a membership points and level system.

1. Mall function construction

1. Create database
   First, we need to create a database to store product information, order information and user information. You can use MySQL or other relational database management systems to create a database named "mall".
2. Create product table
   Create a table named "products" in the "mall" database to store product information.

CREATE TABLE products (
    id INT AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(255),
    description TEXT,
    price DECIMAL(10, 2),
    stock INT
);

3. Create order table
   Create a table named "orders" in the "mall" database to store order information.

CREATE TABLE orders (
    id INT AUTO_INCREMENT PRIMARY KEY,
    user_id INT,
    product_id INT,
    quantity INT,
    amount DECIMAL(10, 2),
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
    FOREIGN KEY (user_id) REFERENCES users(id),
    FOREIGN KEY (product_id) REFERENCES products(id)
);

4. Create user table
   Create a table named "users" in the "mall" database to store user information.

CREATE TABLE users (
    id INT AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(255),
    email VARCHAR(255),
    password VARCHAR(255),
    points INT,
    level TINYINT
);

5. Create registration and login functions
   Use HTML and CSS to build user registration and login pages, and use PHP to handle registration and login requests submitted by users. During registration, user information is inserted into the "users" table. When logging in, check whether the username and password entered by the user match, and save the user information to the session after successful verification.

2. Member points and level system construction

1. Points increase and decrease rules
   In order to motivate users to purchase goods and enhance user loyalty, we can design a set of points Increase and decrease rules. For example, each time a user purchases an item, he or she can earn 10 additional points, and each time a user spends 100 yuan, he or she can earn 50 additional points.
2. Update user points
   Update the user's points after the user purchases goods or consumes successfully.

// 更新用户积分
function updatePoints($userId, $points) {
    // 查询当前用户积分
    $currentPoints = selectPointsByUserId($userId);
    
    // 计算新的积分
    $newPoints = $currentPoints + $points;
    
    // 更新积分
    updatePointsByUserId($userId, $newPoints);
}

3. Member Level Rules
   In order to allow users to enjoy more benefits, we can design a set of membership level rules. According to the number of points of users, users are divided into different levels, and different discounts are provided to users of different levels.
4. Update user level
   Update the user's level based on the user's points.

// 更新用户等级
function updateLevel($userId, $points) {
    // 查询当前用户等级
    $currentLevel = selectLevelByUserId($userId);
    
    // 根据积分数判断新的等级
    if ($points >= 100 && $points < 200) {
        $newLevel = 'Bronze';
    } elseif ($points >= 200 && $points < 500) {
        $newLevel = 'Silver';
    } elseif ($points >= 500 && $points < 1000) {
        $newLevel = 'Gold';
    } elseif ($points >= 1000) {
        $newLevel = 'Platinum';
    } else {
        $newLevel = 'Regular';
    }
    
    // 更新等级
    updateLevelByUserId($userId, $newLevel);
}

5. Member Level Discount
   Different discounts are provided according to the user’s level.

// 根据用户等级获取折扣
function getDiscountByLevel($level) {
    switch ($level) {
        case 'Bronze':
            return 0.95; // 95%折扣
        case 'Silver':
            return 0.9; // 90%折扣
        case 'Gold':
            return 0.85; // 85%折扣
        case 'Platinum':
            return 0.8; // 80%折扣
        default:
            return 1; // 无折扣
    }
}
