按钮每天可点击一次

Question

我有这个按钮，我想让每个用户每天都可以点击一次，例如用户 X 点击它，会出现一条消息说他得到了奖金，如果用户 X 尝试重新点击它会显示他这个消息“你已经得到了今天的每日奖金”或类似的东西。

<?php
session_start();
require_once '../constants/initSite.php';
$siteConstant->addFile('css', 'account.css');
echo $siteConstant->getHead();
echo $siteConstant->getMenu();

if(isset($_SESSION['username']) && isset($_SESSION['password'])){

    require_once '../constants/class.DatabaseConstants.php';
    require_once '../class/class.DBase.php';

    $done = false;

    $db = new DatabaseConstants();
    $dBase = new DBase($db->getHost(), $db->getUser(), $db->getPass());
    $dBase->setDatabaseName($db->getDb());

    if(!$dBase->connectDatabase()){
        die('SQL ERROR at db class vd fn');
    }
    $userQuery = mysqli_query($dBase->getDbobj(), "SELECT * FROM members WHERE username=('".$_SESSION['username']."')");
    if(mysqli_num_rows($userQuery)){
        $userData = mysqli_fetch_assoc($userQuery);
    }else{
        die('User Not Found!');
    }

    $userquery = mysqli_query($dBase->getDbobj(), ('UPDATE members SET dailybonus=1 WHERE username="'.$_SESSION['username'].'"') );

好吧，我不会为你编写代码，不要指望任何人在这里为你编写代码而不自己付出努力。我会告诉你如何去做。你有一个服务器（例如 tomcat）。客户端告诉这个服务器“嘿，我正在点击这个按钮”，服务器就像嗯好的让我检查这个用户的 SQL 数据库。 SQL 数据库然后转到 isButtonClickedToday 或任何内容所在的列，并做出适当的响应。一天结束后，tomcat 服务器与 SQL 服务器通信，“哟，将所有 isButtonClicked 数据设置为 false，现在是新的一天，兄弟”。好了，如果您不知道如何编写此代码，那么您可能应该先学习，然后再提出问题。
