PHP and Vue development: How to implement the expiration of member points

As a membership-based website, points are one of the important means to attract and retain members. However, if points are not properly managed and processed, the value of points will decrease and even cause economic losses. Therefore, the expiration processing of membership points is a necessary function.

In PHP and Vue development, we can implement the expiration processing of membership points through the following steps:

1. Design the database table structure

First, Create a member points table in the database, including the following fields: point ID, member ID, point value, expiration time, etc. Determine if points have expired by setting the Expiration Time field to compare to the current time.

2. Writing PHP back-end code

In the PHP back-end code, we can use scheduled tasks to check and process expired points. The following is a sample code:

<?php
// 这是一个每天定时执行的任务，可以使用Linux系统的cron来实现

// 连接数据库
$mysqli = new mysqli("localhost", "username", "password", "database");

// 检查过期积分
$query = "SELECT * FROM points WHERE expire_date < CURDATE()";
$result = $mysqli->query($query);

if ($result->num_rows > 0) {
    // 处理过期积分
    while ($row = $result->fetch_assoc()) {
        // 执行你希望的处理操作，比如删除过期积分或者给会员发送提醒
        // 例如：删除过期积分
        $deleteQuery = "DELETE FROM points WHERE id = " . $row['id'];
        $mysqli->query($deleteQuery);
    }
}

// 关闭数据库连接
$mysqli->close();
?>

3. Writing Vue front-end code

In the Vue front-end code, we can obtain members’ points by calling the interface provided by the PHP backend information, and display and remind members according to the expiration date.

The following is a sample code that shows how to obtain member points information asynchronously and display expiration reminders:

<template>
  <div>
    <h2>{{ member.name }}的积分：{{ member.points }}</h2>
    
    <p v-if="isExpired">{{ member.name }}的积分将在{{ expireDate }}过期，请尽快使用！</p>
  </div>
</template>

<script>
export default {
  data() {
    return {
      member: {
        id: 1,
        name: "",
        points: 0,
        expireDate: ""
      },
      isExpired: false
    };
  },
  mounted() {
    // 异步获取会员积分信息
    axios.get("/api/member/1/points")
      .then(response => {
        this.member = response.data;
        
        // 检查积分是否过期
        if (new Date(response.data.expireDate) < new Date()) {
          this.isExpired = true;
        }
      })
      .catch(error => {
        console.log(error);
      });
  }
};
</script>

<style>
/* 样式代码 */
</style>

Through the above steps, we can implement the expiration processing of member points. The PHP back-end code will regularly check expired points and perform corresponding processing operations, while the Vue front-end code will display and remind members of the expiration of points based on the expiration time.

It should be noted that the above code is only an example, and the specific implementation method may differ according to specific business needs. For example, you may need to add more fields to store information such as the source of points, usage records, etc. In addition, in order to ensure the security and reliability of the code, the back-end code also needs to be optimized and error handled.

In short, through reasonable database design, PHP back-end code and Vue front-end code writing, we can realize the function of member points expiration processing, thereby improving the user experience of the website and member management efficiency.
