PHP and Vue: How to implement the extension mechanism of the validity period of member points

Introduction:
Member points are a common reward mechanism in e-commerce platforms, which can motivate members They continue to purchase and participate in activities. However, for some points rules, points have a validity period. Once the points expire, they cannot be used, causing trouble to members. This article will introduce how to use PHP and Vue to implement the membership points validity extension mechanism, and provide specific code examples.

1. Back-end implementation
Use PHP on the back-end to implement the membership points validity extension mechanism. We need the following steps:

1. Create database table
   Create A database table named "members" is used to store member information, including member ID, points, validity period and other fields.

CREATE TABLE members (
    id INT PRIMARY KEY AUTO_INCREMENT,
    name VARCHAR(255) NOT NULL,
    points INT NOT NULL,
    expire_date DATE NOT NULL
);

2. PHP code logic
   In the PHP code, we can use the following logic to extend the validity period of membership points:

// 获取当前时间
$currentDate = date('Y-m-d');

// 查询会员信息
$query = "SELECT * FROM members";
$result = mysqli_query($connection, $query);

// 遍历每个会员
while ($row = mysqli_fetch_assoc($result)) {
    $expireDate = $row['expire_date'];
    $points = $row['points'];
    $id = $row['id'];

    // 如果当前时间大于有效期并且积分大于0
    if ($currentDate > $expireDate && $points > 0) {
        // 将有效期延长一年
        $newExpireDate = date('Y-m-d', strtotime('+1 year', strtotime($expireDate)));
        
        // 更新数据库中的有效期字段
        $updateQuery = "UPDATE members SET expire_date = '$newExpireDate' WHERE id = '$id'";
        mysqli_query($connection, $updateQuery);
    }
}

2. Front-end To implement
Use Vue on the front end to implement the membership points validity extension mechanism, we need the following steps:

1. Create a Vue component
   Create a Vue component named "MemberList", use It is used to display the member list and provide the function of extending the validity period of points.

<template>
  <div>
    <ul>
      <li v-for="member in members" :key="member.id">
        <span>{{ member.name }}</span>
        <span>{{ member.points }}</span>
        <span>{{ member.expireDate }}</span>
        <button @click="extendExpireDate(member.id)">延长有效期</button>
      </li>
    </ul>
  </div>
</template>

<script>
export default {
  data() {
    return {
      members: [],
    };
  },
  mounted() {
    this.fetchMembers();
  },
  methods: {
    fetchMembers() {
      // 调用API获取会员列表
      // ...

      // 将数据存储到this.members中
      // ...
    },
    extendExpireDate(id) {
      // 调用API将指定会员的有效期延长
      // ...

      // 更新this.members中对应会员的有效期
      // ...
    },
  },
};
</script>

2. Calling the back-end API
   In the Vue component, we can use tools such as axios to call the back-end API interface to extend the validity period of membership points.

axios.post('/api/extendExpireDate', { id: memberId })
  .then(response => {
    // 成功延长有效期后，更新会员列表中对应会员的有效期
    const updatedMembers = this.members.map(member => {
      if (member.id === memberId) {
        return { ...member, expireDate: response.data.expireDate };
      }
      return member;
    });

    this.members = [...updatedMembers];
  })
  .catch(error => {
    // 处理错误
  });

3. Summary
By using PHP and Vue to handle the back-end logic and front-end interface respectively, we can implement the extension mechanism of the membership points validity period. The backend uses PHP's database operation function to query and update member information, and the frontend uses Vue to display the member list and call the backend API to extend the validity period. The above are the basic ideas and code examples for implementing this function. The specific implementation method can be adjusted and expanded according to project needs.
