一、web前端及ajax部分文件index.html

<html> <head> <meta http-equiv=Content-Type content="text/html;charset=utf-8"> <title>PHP+AJAX+MYSQL实现每日签到</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>

二、PHP后端处理部分

sign.php文件<?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. } ?>

三、Mysql数据库部分

CREATE TABLE IF NOT EXISTS `sign` (
`uid` int(11) NOT NULL,
`dateline` varchar(10) COLLATE utf8_bin NOT NULL, PRIMARY KEY (`uid`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_bin;INSERT INTO `sign` (`uid`, `dateline`) VALUES (1, '1389072071'), (2, '1389072735'); CREATE TABLE IF NOT EXISTS `user` (
`id` int(11) NOT NULL AUTO_INCREMENT COMMENT 'USERID',
`username` varchar(35) COLLATE utf8_bin NOT NULL COMMENT 'username',
`signdays` int(11) NOT NULL COMMENT '签到天数', PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_bin AUTO_INCREMENT=3 ;INSERT INTO `user` (`id`, `username`, `signdays`) VALUES (1, 'ggbound', 4), (2, 'other', 1);
