Design ideas for mall points system developed with PHP

Introduction:
With the development of e-commerce, mall points system has become an indispensable part of major e-commerce platforms. The points system can not only improve user shopping experience, but also increase user stickiness and encourage users to return to shopping. This article will introduce how to develop a simple mall points system using PHP and provide code examples.

1. System requirements analysis:
The mall points system mainly has the following functional modules:

1. User registration and login: Users need to register an account and log in to the system to obtain, Use points.
2. Points acquisition: Users can obtain points by shopping, participating in activities, etc.
3. Use of points: Users can use points to deduct part or all of the product amount.
4. Points inquiry: Users can check their points balance.
5. Points record: records the user’s points acquisition and usage records to facilitate user query and system management.

2. System design:

1. Data table design:
   Based on demand analysis, we need to design the following database tables:
2. users : Stores basic user information, such as username, password, email, etc.
3. points: Stores the user's points information, such as user ID, point balance, etc.
4. transactions: Stores the user's points consumption and acquisition records, including time, type, number of points, etc.
5. User registration and login:
   When users register, they need to provide user name, password and email information. We can insert new user records in the users table. When users log in, they need to verify whether the username and password are correct. After passing the verification, the user information can be stored in the session for subsequent use.
6. Points acquisition and use:
   a. Points acquisition: When the user completes shopping or participates in an activity, the corresponding points need to be added to the user's points balance. A record can be inserted into the transactions table to record the user ID, number of points, type (shopping, activities, etc.) and time.
   b. Points use: When a user chooses to use points to deduct the amount when shopping, the number of points selected by the user needs to be converted into the deduction amount, and the corresponding points are subtracted from the user's points balance. You can also insert a record into the transactions table to record the user ID, number of points, type (deduction) and time.
7. Points query:
   Users can query their points balance by calling the interface. Retrieve the record of the corresponding user ID in the points table, obtain the points balance and return it to the user.
8. Points record:
   Record the user's points acquisition and usage records in the transactions table to facilitate user query and administrator processing.

3. Code example:
The following is a simple PHP code example to demonstrate the user login and points query functions:

// User login
function login($username, $password) {
// Verify that the username and password are correct
$user = getUserByUsername($username);
if($user && $user['password'] == $ password) {

// 登录成功，将用户信息存储在session中
$_SESSION['user'] = $user;
return true;

} else {

return false;

}
}

// Points query
function getPoints($userId) {
// Query the user's points balance
$points = getPointsByUserId($userId);
return $points;
}

// Calling example
session_start();
if( login('user1', 'password123')) {
$userId = $_SESSION'user';
$points = getPoints($userId);
echo "The current user's point balance is:" . $points;
} else {
echo "Login failed";
}

Conclusion:
This article introduces the design ideas of using PHP to develop the city points system and provides the code Example. Through the above design ideas and examples, we can carry out secondary development according to needs to implement a simple and practical mall points system to improve user shopping experience and user stickiness of the platform. hope that it can help us!
