在現在的好多網站上都出現了每日簽到以及簽到送禮等互動功能，這邊呢，作者就使用最原始的PHP配合MYSQL、AJAX來制作了一個簡單的每日簽到功能，至於送禮還有其他的小游戲就需要讀者們自己去增加和拓展了。
下面先看下文件目錄：
database：
顧名思義就是存放數據庫SQL語句的文件，里面存放了已經設計好的簡單的幾張表。
js：
存放JS腳本庫。
index.php
用的是.PHP為后綴的，其實下面看到后，讀者可能會說，里面沒PHP代碼，直接弄成.HTML的后綴好了，其實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實現簽到</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(){ $.get("/sign.php?do=sign",{},function(data){ if(data==1){ alert("sign success!"); window.location.href='/'; }else if(data==2){ alert("already sign today! next tomorrow!"); } }); } </script> </head> <body> <a style="cursor:pointer;" onclick="doSign();">簽到<span>連續簽到<span id="days"></span>天</span></a> </body> </html>
sign.php 該文件就是具體處理簽到的PHP代碼了，具體的code如下：
<?php if ($_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.
}
}
?>
數據庫：測試數據庫結構及具體內容如下：
-- phpMyAdmin SQL Dump -- version 3.4.8 -- http://www.phpmyadmin.net -- -- Host: localhost -- Generation Time: Jan 07, 2014 at 01:32 PM -- Server version: 5.5.28 -- PHP Version: 5.2.17p1 SET SQL_MODE="NO_AUTO_VALUE_ON_ZERO"; SET time_zone = "+00:00"; /*!40101 SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT */; /*!40101 SET @OLD_CHARACTER_SET_RESULTS=@@CHARACTER_SET_RESULTS */; /*!40101 SET @OLD_COLLATION_CONNECTION=@@COLLATION_CONNECTION */; /*!40101 SET NAMES utf8 */; -- -- Database: `sign` -- -- -------------------------------------------------------- -- -- Table structure for table `sign` -- 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; -- -- Dumping data for table `sign` -- INSERT INTO `sign` (`uid`, `dateline`) VALUES (1, '1389072071'), (2, '1389072735'); -- -------------------------------------------------------- -- -- Table structure for table `user` -- 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 '簽到天數', 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 */;
到此一個每日簽到的功能就基本完成了！
