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

复制代码4.后台代码：查询今天是否签到：

复制代码$points = M('points_log');$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);

复制代码5.查询积分：

复制代码/*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);

复制代码6.签到写入数据库：

复制代码/*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);

}

复制代码7. /*查询本月签到天数，并以json格式返回*/复制代码public functionMonthSign(){$userid=session('user.id');$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');

}
