本文主要介绍了php+mysql+jquery实现日历签到功能的过程与步骤，具有很好的参考价值

在网站开发过程中我们会经常用到签到功能来奖励用户积分，或者做一些其他活动。这次项目开发过程中做了日历签到，因为没有经验所有走了很多弯路，再次记录过程和步骤。

1.日历签到样式：

2.本次签到只记录本月签到数，想要查询可以写其他页面，查询所有签到记录。(功能有，非常麻烦，古没有做。)

3.前台代码

*{margin:0;padding:0;font:14px/1.8 "Helvetica Neue","microsoft yahei";}

签到记录

已签到

立即签到

function MonthSign(){

//ajax获取日历json数据

type:'POST',

datatype:"json",

success:function(msg){

//alert(msg);

/*var signList=[{"signDay":"10"},{"signDay":"11"},{"signDay":"12"},{"signDay":"13"}];

var dPrevDate = new Date(iYear, iMonth, 0);

return dPrevDate.getDate();

},

aMonth[1] = new Array(7);

}

}

htmls.push("

");

}

htmls.push("

");

htmls.push("

");

htmls.push("

");

return htmls.join('');

}

};

4.后台代码：查询今天是否签到：

$points = M('points_log');

$userid=session('user.id');

$begintime=date("Y-m-d H:i:s",mktime(0,0,0,date('m'),date('d'),date('Y')));

$endtime=date("Y-m-d H:i:s",mktime(0,0,0,date('m'),date('d')+1,date('Y'))-1);

$where=array(

'points'=>'5',

'user_id'=>$userid,

'createtime' => array(array('gt',$begintime),array('lt',$endtime)),

);

$res=$points->where($where)->order("createtime desc")->select();

//var_dump($res['0']['points']);

$this->assign('res',$res);

5.查询积分：

/*查询积分*/

$jfen=M(cuser);

$list=$jfen->where(array('id'=>$userid))->field('points')->find();

$preg = '/[0]*/';

$poin = preg_replace($preg, '', $list, 1);

$this->assign('poin',$poin);

6.签到写入数据库：

/*签到*/

if(IS_AJAX){

$userid=session('user.id');

$type='签到';

$typename='checkin';

$id_status='up';

$date=Date('Y-m-d H:i:s');

$dataList=array(

'user_id'=>$userid,

'type'=>$type,

'typename'=>$typename,

'id_status'=>$id_status,

'points'=>'5',

'createtime'=>$date,

'remark'=>'奖励5积分'

);

$points = M('points_log');

if($points->add($dataList)){

$log=session('user.id');

$user=M('cuser');

$user->where(array('id'=>$log))->setInc('points',5);

}

$this->ajaxReturn($status);

}

7. /*查询本月签到天数，并以json格式返回*/

public function MonthSign(){

$userid=session('user.id');

$points = M('points_log');

$res=$points->where(array('user_id'=>$userid))->select();

$sign='[';

foreach($res as $key=>$value){

$first=explode(' ', $value['createtime']);

$second=explode('-', $first['0'])['2'];

if($key==0){

$sign .= '{"signDay":"'.$second.'"}';

}else{

$sign .= ',{"signDay":"'.$second.'"}';

}

}

$sign .=']';

$this->ajaxReturn($sign,'json');

}
