PHP+MYSQL+AJAX实现每日签到

在现在的好多网站上都出现了每日签到以及签到送礼等互动功能，这边呢，作者就使用最原始的PHP配合MYSQL、AJAX来制作了一个简单的每日签到功能，至于送礼还有其他的小游戏就需要读者们自己去增加和拓展了。

下面先看下文件目录：

database：

顾名思义就是存放数据库SQL语句的文件，里面存放了已经设计好的简单的几张表。

js：

存放JS脚本库。

index.php

用的是.PHP为后缀的，其实下面看到后，读者可能会说，里面没PHP代码，直接弄成.HTML的后缀好了，其实大家可以自己去修改的，作者就不更改了。

index.php code:

<html>  
    <head>  
        <meta http-equiv=Content-Type content="text/html;charset=utf-8">  
        <title>PHP+AJAX+MYSQL实现签到</title>  
        <script type="text/javascript" src="js/jquery.min.js"></script>  
        <script type="text/javascript">  
            //page load get num  
            $(window).ready(function(){  
                doGetDays();  
            });  
            //get sign days  
            function doGetDays(){  
                $.get("/sign.php?do=getDay",{},function(data){  
                    $("#days").html(data);  
                });  
            }  
            //do  sign  
            function doSign(){  
                $.get("/sign.php?do=sign",{},function(data){  
                    if(data==1){  
                        alert("sign success!");  
                        window.location.href='/';  
                    }else if(data==2){  
                        alert("already sign today! next tomorrow!");      
                    }  
                });  
            }  
        </script>  
    </head>  
    <body>  
        <a style="cursor:pointer;" onclick="doSign();">签到<span>连续签到<span id="days"></span>天</span></a>  
    </body>  
</html>

sign.php 该文件就是具体处理签到的PHP代码了，具体的code如下：

<?php      
      
    if ($_GET['do']=='getDay'){  
        $db=new mysqli('localhost','root','123456','sign');  
        $uid=2;  
        $getDay="SELECT `signdays` FROM `user` WHERE `id`= {$uid}";  
        $day=$db -> query($getDay);  
        $days =$day -> fetch_array(MYSQLI_ASSOC);  
        echo $days['signdays'];  
    }  
      
    if ($_GET['do']=='sign'){  
        $db=new mysqli('localhost','root','123456','sign');  
        $uid=2;  
        $time=time();  
        //check sign today ?  
        $todayBegin=strtotime(date('Y-m-d')." 00:00:00");  
        $todayEnd= strtotime(date('Y-m-d')." 23:59:59");  
        $checkSignSql="SELECT * FROM `sign` WHERE `uid` = {$uid} AND `dateline` < {$todayEnd} AND `dateline` > {$todayBegin} ";  
        $checkSignToday= $db -> query($checkSignSql);  
        $checkSign = $checkSignToday -> fetch_array(MYSQLI_ASSOC);  
        if (empty($checkSign)){  
            $sql="SELECT * FROM `sign` WHERE `uid` = {$uid} ";  
            $return = $db -> query($sql) -> fetch_array(MYSQL_ASSOC);//check sign table exist uid record ?  
            if (empty($return)){//no  
                $insertSql="INSERT INTO `sign` (`uid`,`dateline`) VALUES ('{$uid}','{$time}') ";  
                $insert = $db -> query($insertSql);  
                $updateSignSql="UPDATE `user` SET `signdays` =1 WHERE `id` = {$uid} ";  
                $db -> query($updateSignSql);  
                echo 1;  
            }else{  
                // check is continuous ? reset with login set signdays as 0 !!!!!  
                $yesterdayBegin= strtotime(date("Y-m-d",strtotime("-1 day"))." 00:00:00");  
                $yesterdayEnd= strtotime(date("Y-m-d",strtotime("-1 day"))." 23:59:59");  
                $checkContinuSql="SELECT * FROM `sign` WHERE `uid` = {$uid} AND `dateline` < {$yesterdayEnd} AND `dateline` > {$yesterdayBegin}";  
                $checkContinuYesterday = $db ->query($checkContinuSql) -> fetch_array(MYSQL_ASSOC); 　　　　　　　　　if (!empty($checkContinuYesterday)){ 　　　　　　　　　　　$replaceSql="REPLACE INTO `sign` (`uid`,`dateline`) VALUES ('{$uid}','{$time}') "; 　　　　　　　　　　　$replace=$db -> query($replaceSql); $updateSignSql="UPDATE `user` SET `signdays` = `signdays` + 1 WHERE `id` = {$uid} ";　　　　　　　　　　　$db -> query($updateSignSql); echo 1; 　　　　　　　　　　}else{　　　　　　　　　　　　　　　　　　　　} 　　　　　　　} 　　　　}else{ 　　　　　　echo 2;// allready sign.   　　　　} } ?>

数据库：测试数据库结构及具体内容如下：

INSERT INTO `sign` (`uid`, `dateline`) VALUES

  `signdays` int(11) NOT NULL COMMENT '签到天数',  
  PRIMARY KEY (`id`)  
) ENGINE=MyISAM  DEFAULT CHARSET=utf8 COLLATE=utf8_bin AUTO_INCREMENT=3 ;  
  
--  
-- Dumping data for table `user`  
--  
  
INSERT INTO `user` (`id`, `username`, `signdays`) VALUES  
(1, 'ggbound', 4),  
(2, 'other', 1);  
  
/*!40101 SET CHARACTER_SET_CLIENT=@OLD_CHARACTER_SET_CLIENT */;  
/*!40101 SET CHARACTER_SET_RESULTS=@OLD_CHARACTER_SET_RESULTS */;  
/*!40101 SET COLLATION_CONNECTION=@OLD_COLLATION_CONNECTION */;

到此一个每日签到的功能就基本完成了！
