php+mysql+jquery实现日历签到

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');
  }
