使用PHP和Vue实现支付后会员积分的积分有效期延长方法

<?php
// 设置数据库信息
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "members_db";

// 建立数据库连接
$conn = new mysqli($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);
}

// 接收POST请求中的会员ID和支付金额
$member_id = $_POST['member_id'];
$payment_amount = $_POST['payment_amount'];

// 查询会员信息
$sql = "SELECT * FROM members WHERE id = '" . $member_id . "'";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // 找到会员信息
    $member = $result->fetch_assoc();

    // 计算新的积分有效期
    $new_expiry_date = date('Y-m-d H:i:s', strtotime($member['expiry_date']) + $payment_amount);

    // 更新会员积分有效期
    $update_sql = "UPDATE members SET expiry_date = '" . $new_expiry_date . "' WHERE id = '" . $member_id . "'";
    $conn->query($update_sql);

    echo "积分有效期已延长";
} else {
    echo "找不到会员信息";
}

$conn->close();
?>
