实现客户签到功能

使用PHP实现客户签到功能需要结合数据库操作和前端交互。以下是一个基本的实现方案：

php实现客户签到

数据库设计

创建一张签到表存储签到记录：

php实现客户签到

CREATE TABLE user_check_in (
    id INT AUTO_INCREMENT PRIMARY KEY,
    user_id INT NOT NULL,
    check_in_date DATE NOT NULL,
    check_in_time DATETIME NOT NULL,
    points_earned INT DEFAULT 0,
    UNIQUE KEY (user_id, check_in_date)
);

签到核心代码

<?php
// 连接数据库
$db = new PDO('mysql:host=localhost;dbname=your_db', 'username', 'password');

// 获取用户ID
$userId = $_SESSION['user_id'] ?? 0;

// 检查今日是否已签到
$stmt = $db->prepare("SELECT * FROM user_check_in WHERE user_id = ? AND check_in_date = CURDATE()");
$stmt->execute([$userId]);
$hasCheckedIn = $stmt->fetch();

if (!$hasCheckedIn && $userId) {
    // 执行签到
    $points = 10; // 每次签到获得10积分

    $stmt = $db->prepare("INSERT INTO user_check_in (user_id, check_in_date, check_in_time, points_earned) 
                         VALUES (?, CURDATE(), NOW(), ?)");
    $stmt->execute([$userId, $points]);

    // 更新用户总积分
    $stmt = $db->prepare("UPDATE users SET points = points + ? WHERE id = ?");
    $stmt->execute([$points, $userId]);

    echo json_encode(['success' => true, 'message' => '签到成功，获得'.$points.'积分']);
} else {
    echo json_encode(['success' => false, 'message' => '今日已签到']);
}
?>

前端交互示例

function checkIn() {
    fetch('check_in.php')
        .then(response => response.json())
        .then(data => {
            alert(data.message);
            if(data.success) {
                // 更新UI显示
                document.getElementById('checkInBtn').disabled = true;
            }
        });
}

连续签到奖励

可以扩展签到逻辑实现连续签到奖励：

// 检查昨日是否签到
$stmt = $db->prepare("SELECT check_in_date FROM user_check_in 
                     WHERE user_id = ? AND check_in_date = DATE_SUB(CURDATE(), INTERVAL 1 DAY)");
$stmt->execute([$userId]);
$yesterdayChecked = $stmt->fetch();

// 计算连续签到天数
if ($yesterdayChecked) {
    $stmt = $db->prepare("SELECT consecutive_days FROM users WHERE id = ?");
    $stmt->execute([$userId]);
    $consecutiveDays = $stmt->fetchColumn();
    $consecutiveDays = $consecutiveDays ? $consecutiveDays + 1 : 2;

    // 根据连续天数计算奖励
    $points = min(10 * $consecutiveDays, 100); // 最多100积分

    // 更新连续签到天数
    $stmt = $db->prepare("UPDATE users SET consecutive_days = ? WHERE id = ?");
    $stmt->execute([$consecutiveDays, $userId]);
} else {
    // 重置连续签到
    $stmt = $db->prepare("UPDATE users SET consecutive_days = 1 WHERE id = ?");
    $stmt->execute([$userId]);
    $points = 10;
}
