控制器里面调用方法：

        $db = M('teamnotice');
        $notice = $db -> where(array('noticeid' => $noticeid)) ->find();
        $mytids = M('users') -> field('tids') -> where(array('uid'=> session('uid'))) ->find();
        if($notice['acceptuids'] !=0 && !in_uid(session('uid'),$notice['acceptuids']))$this->error('Sorry!','/App');/*不在拒绝查看ID范围内*/
        if(!in_uid($notice['tid'],$mytids['tids']))$this->error('Sorry!','/App');/*不在同一个团队不能查看*/
        if($notice['receipt']==2){/*如果已查看*/
            $data['noreceipts'] = removeUid(session('uid'),$notice['noreceipts']);
            $data['count'] = array('exp','count + 1');
            $db ->where(array('noticeid' => $id)) -> save($data);/*更新未发送回执者*/
        }else{
            $db -> where(array('noticeid' => $id)) -> save(array('count' => array('exp','count + 1 ')));
        }
        $notice['userfriend'] = M('userfriend') ->where(array('uid'=>session('uid')))->find();
        $notice['count'] += 1;
        $cdb = M('teamcomment');
        $teamcomment = $comment = $cdb -> where(array('noticeid'=>$id ,'status' => 1)) -> order('commentid desc') ->page($p,20)->select();
        $notice['commentNum'] = $count= $cdb ->where(array('noticeid'=>$id ,'status' => 1))->count();
        $Page = new ThinkPagemini($count,20);
        $page_tpl = urlencode('[PAGE]'); 
        $Page->url = "/Team/Notice/pages/?id=$id&p={$page_tpl}";
        $show = $Page->show();// 分页显示输出
        //$teamcomment['count'] = countString($comment['count']);
        $notice['teamcomment'] = $teamcomment;
        $this -> assign('notice',$notice);

    }

        $n = $db-> field('acceptuids')-> where(array('noticeid' => $noticeid)) ->find();
        $mytids = M('users') -> field('tids') -> where(array('uid'=> session('uid'))) ->find();
        if($n['acceptuids'] !=0 && !in_uid(session('uid'),$n['acceptuids']))$this->ajaxReturn(array('page'=>'Sorry!No author access'));/*不在拒绝查看ID范围内*/
         $cdb = M('teamcomment');
        $notice['teamcomment'] = $cdb -> where(array('noticeid'=>$id ,'status' => 1)) -> order('commentid desc') ->page($p,20)->select();
        foreach ($notice['teamcomment'] as $k => $v) {
            $name = getUserRealName(session('uid'),$v['uid']);
            $notice['teamcomment'][$k]['rname'] = $name['tname'];
            $notice['teamcomment'][$k]['head'] = getBighead($v['uid']);
            $notice['teamcomment'][$k]['ctime'] = date('m-d H:i',$v['ctime']);
            $notice['teamcomment'][$k]['zan'] = countString($v['zan']);
            $notice['teamcomment'][$k]['jubao'] = ($v['jubao'] == '' || is_null($v['jubao'])) ? 0 : count(explode(',',$v['jubao']));            
        }
        $count = $cdb ->where(array('noticeid'=>$id ,'status' => 1))->count();
        $Page = new ThinkPagemini($count,20);
        $page_tpl = urlencode('[PAGE]'); 
        $Page->url = "/Team/Notice/pages/?id=$id&p={$page_tpl}";
        $notice['page'] = $Page->show();// 分页显示输出
