PHP와 Vue: 멤버십 포인트 누적 계산을 구현하는 방법

<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

// 创建数据库连接
$conn = new mysqli($servername, $username, $password, $dbname);

// 检查连接是否成功
if ($conn->connect_error) {
    die("数据库连接失败: " . $conn->connect_error);
}
?>

<?php
// 获取会员ID和积分值
$member_id = $_POST['member_id'];
$points = $_POST['points'];

// 更新会员积分
$sql = "UPDATE users SET points = points + $points WHERE id = $member_id";

if ($conn->query($sql) === TRUE) {
    echo "会员积分更新成功";
} else {
    echo "会员积分更新失败: " . $conn->error;
}

// 关闭数据库连接
$conn->close();
?>

npm install axios

<script>
import axios from 'axios';

export default {
  data() {
    return {
      member_id: '',
      points: '',
    };
  },
  methods: {
    updatePoints() {
      axios.post('http://localhost/update_points.php', {
        member_id: this.member_id,
        points: this.points,
      }).then(response => {
        console.log(response.data);
      }).catch(error => {
        console.error(error);
      });
    },
