Thinkphp篩選數據，根據不同條件切換不同導航鏈接，根據過期時間篩選數據

 $map = array('closed' => 0, 'user_id' => $this->uid, 'ltime' => array('GT', TODAY));
        $aready = (int) $this->_param('aready');
        if ($aready == 1) {
            //$map['closed'] = 0;
           $map['ltime'] = array('GT', TODAY);//進行中
        }elseif ($aready == 2) {
          //  $map['closed'] = 1;//往期
            $map['ltime'] = array('ELT', TODAY);//往期
        }
        $count = $Crowd->where($map)->count();
