    后台调用

     $User = M('api_article'); // 实例化User对象
                $count      = $User->where(array('er_id'=>$id))->count();// 查询满足要求的总记录数
                $Page       = new ThinkPage($count,2);// 实例化分页类 传入总记录数和每页显示的记录数(25)
                $show       = $Page->show();// 分页显示输出
    // 进行分页数据查询 注意limit方法的参数要使用Page类的属性
                $article = $User->where(array('er_id'=>$id))->order('fabutime desc')->limit($Page->firstRow.','.$Page->listRows)->select();
                $this->assign('show',$show);// 赋值分页输出
           $this->assign('article', $article);//二级分类文章列表       

    $this->display();
