How to use PHP and Vue to develop the redemption record of member points after payment

Introduction:
With the rapid development of e-commerce and mobile payment, more and more Many companies choose to provide points systems for members to attract more users and enhance user loyalty. In this article, we will introduce how to use PHP and Vue to develop a simple post-payment membership points redemption record function, and provide specific code examples.

1. Requirements Analysis
Before starting development, we first need to analyze our needs. We need to implement the following functions:

1. Users can purchase goods through payment and obtain corresponding points.
2. Users can use points to redeem products, and the redemption record will be saved and displayed in the user's personal center interface.
3. The administrator can view the redemption records of all users and perform corresponding management operations.

2. Technology Selection
For developing this function, we chose to use PHP as the back-end development language and Vue as the front-end development framework. At the same time, we also need to use MySQL to store the user's redemption record information.

3. Database design
In the database, we need to create the following tables:

1. User table (users), used to store basic information of users.
2. The product table (goods) is used to store basic information about the product.
3. Points record table (points), used to store users’ points redemption records.

4. Back-end development

1. First we need to create a PHP file to process the user's payment request. We can use the API of the third-party payment platform to implement the payment function and obtain the order number and points after successful payment.
2. After the user successfully pays and obtains points, we need to save the order number, number of points, user ID, product ID and other information into the points record table.

The following is a simple PHP code example for processing the user's payment request and saving the points record information:

<?php
// 处理用户支付请求
// 获取支付成功的订单号和积分数
$orderId = $_POST['orderId'];
$points = $_POST['points'];

// 保存积分记录到数据库
$userId = $_SESSION['userId'];
$productId = $_POST['productId'];

$sql = "INSERT INTO points (order_id, points, user_id, product_id) VALUES ('$orderId', '$points', '$userId', '$productId')";
// 执行 SQL 语句（需要自己实现数据库连接和执行方法）
$result = execute($sql);
if ($result) {
    echo "保存成功";
} else {
    echo "保存失败";
}
?>

2. Next, we need to create a PHP interface , used to obtain the user’s points redemption record. The following is a simple PHP code example:

<?php
// 获取用户的积分兑换记录
$userId = $_SESSION['userId'];

$sql = "SELECT * FROM points WHERE user_id = '$userId'";
// 执行 SQL 语句（需要自己实现数据库连接和执行方法）
$result = execute($sql);

// 将结果返回给前端
echo json_encode($result);
?>

5. Front-end development

1. In the front-end interface, we need to create a redemption record page to display the user’s Points redemption records. We can use Vue to implement interface rendering and data binding.

The following is a simple Vue code example to display the user's points redemption record:

<template>
  <div>
    <h2>我的积分兑换记录</h2>
    <ul>
      <li v-for="record in records" :key="record.id">
        <p>订单号：{{ record.orderId }}</p>
        <p>兑换积分：{{ record.points }}</p>
        <p>兑换时间：{{ record.created_at }}</p>
      </li>
    </ul>
  </div>
</template>

<script>
export default {
  data() {
    return {
      records: []
    };
  },
  mounted() {
    // 在组件加载完成后，从后端接口获取用户的积分兑换记录
    this.getRecords();
  },
  methods: {
    getRecords() {
      // 发送请求到后端接口
      axios.get('/api/records')
        .then(response => {
          this.records = response.data;
        })
        .catch(error => {
          console.error(error);
        });
    }
  }
};
</script>

2. Finally, we need to create an administrator interface for display Points redemption records for all users. The implementation of this interface is similar to the user interface, except that a different backend interface needs to be called to obtain the point redemption records of all users.

6. Summary
This article introduces how to use PHP and Vue to develop a simple redemption record function for member points after payment. We analyzed the requirements, selected the appropriate technology and database design, and provided specific code examples. Developers can make corresponding modifications and extensions based on actual needs and business logic to meet their own needs. I hope this article can be helpful to everyone.
