实现日历签到功能

日历签到功能通常包括用户每日签到记录、连续签到统计以及奖励机制。以下是实现这一功能的详细步骤：

数据库设计

创建签到记录表，包含用户ID、签到日期和连续签到天数等字段：

CREATE TABLE user_checkins (
    id INT AUTO_INCREMENT PRIMARY KEY,
    user_id INT NOT NULL,
    checkin_date DATE NOT NULL,
    consecutive_days INT DEFAULT 1,
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
    UNIQUE KEY (user_id, checkin_date)
);

签到逻辑处理

编写PHP代码处理签到请求，检查用户是否已签到并更新连续签到天数：

function handleCheckin($userId) {
    $today = date('Y-m-d');
    $pdo = new PDO('mysql:host=localhost;dbname=your_db', 'username', 'password');

    // 检查今日是否已签到
    $stmt = $pdo->prepare("SELECT * FROM user_checkins WHERE user_id = ? AND checkin_date = ?");
    $stmt->execute([$userId, $today]);
    if ($stmt->rowCount() > 0) {
        return ['status' => 'error', 'message' => '今日已签到'];
    }

    // 获取昨日签到记录
    $yesterday = date('Y-m-d', strtotime('-1 day'));
    $stmt = $pdo->prepare("SELECT consecutive_days FROM user_checkins WHERE user_id = ? AND checkin_date = ?");
    $stmt->execute([$userId, $yesterday]);
    $consecutiveDays = $stmt->rowCount() > 0 ? $stmt->fetch()['consecutive_days'] + 1 : 1;

    // 记录今日签到
    $stmt = $pdo->prepare("INSERT INTO user_checkins (user_id, checkin_date, consecutive_days) VALUES (?, ?, ?)");
    $stmt->execute([$userId, $today, $consecutiveDays]);

    return ['status' => 'success', 'consecutive_days' => $consecutiveDays];
}

日历显示实现

生成日历视图并标记已签到日期：

function generateCalendar($userId, $year, $month) {
    $pdo = new PDO('mysql:host=localhost;dbname=your_db', 'username', 'password');
    $stmt = $pdo->prepare("SELECT checkin_date FROM user_checkins WHERE user_id = ? AND YEAR(checkin_date) = ? AND MONTH(checkin_date) = ?");
    $stmt->execute([$userId, $year, $month]);
    $signedDates = array_column($stmt->fetchAll(), 'checkin_date');

    $daysInMonth = date('t', mktime(0, 0, 0, $month, 1, $year));
    $calendar = [];

    for ($day = 1; $day <= $daysInMonth; $day++) {
        $date = sprintf('%04d-%02d-%02d', $year, $month, $day);
        $calendar[$day] = [
            'date' => $date,
            'signed' => in_array($date, $signedDates)
        ];
    }

    return $calendar;
}

前端展示

使用HTML/CSS展示日历和签到按钮：

<div class="calendar">
    <?php foreach ($calendar as $day => $data): ?>
        <div class="day <?= $data['signed'] ? 'signed' : '' ?>">
            <span class="date"><?= $day ?></span>
            <?= $data['signed'] ? '✓' : '' ?>
        </div>
    <?php endforeach; ?>
</div>

<button id="checkin-btn" onclick="handleCheckin()">每日签到</button>

奖励机制实现

根据连续签到天数发放奖励：

php实现日历签到

function giveReward($userId, $consecutiveDays) {
    $rewards = [
        3 => ['type' => 'points', 'amount' => 100],
        7 => ['type' => 'points', 'amount' => 300],
        30 => ['type' => 'vip', 'days' => 1]
    ];

    if (isset($rewards[$consecutiveDays])) {
        $reward = $rewards[$consecutiveDays];
        // 实现发放奖励的逻辑
        return $reward;
    }

    return null;
}
