php+mysql+jquery日历签到

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

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');
    }
