volist 、获取IP和事件以及分页功能

1、Volist标签主要用于在模板中循环输出数据集或者多维数组。

2、

前台显示ip和time  建表的时候两个数据类型都选vachar，然后在添加数据的时候

 public function add(){

      import('ORG.Util.Date');

       $user=D('liuyan');

       if($vo=$user->create()){

           echo 'create成功';

            $list = array('title' => I('title'),

                                     'content'=> I('content'),

                                     'time'=> time(),

                               'name'=>I('name'),

                 'tel'=>I('tel'),

                 'email'=>I('email'),

                

                 'ip'=>get_client_ip());

            

           if ($user->add($list)){ 

               $list['id']=$id;

            $list['title']=$title;

           $list['time'] = date('Y-m-d H:i:s', time());

           $list['ip'] = $_SERVER['REMOTE_ADDR'];

         

              $this->success("发布留言成功"); 

           }else{ 

                $this->error($user->getError()); 

           } 

       }else{ 

           echo 'create失败'; 

           $this->error($user->getError()); 

           

       }

3、

分页功能

 $User=M("liuyan");

        import('ORG.Util.Page');

                 

                            $count = $User->count();

 

                            $Page= new Page($count ,5);

                            $limit= $Page->firstRow . ',' . $Page->listRows;

                        $show =$Page->show();// 分页显示输出

                            $list= $User->order('time')->limit($limit)->select();

 

                            $this->assign('list',$list);

                            $this->assign('page',$show);

                            $this->display();

 

再在模板页面中写上

         <div class="result page">{$page}</div>
