1、$aid文章ID
2、$typeid文章所属栏目ID
3、$act当前文章所属栏目的标识
4、$ksOne文章一级栏目名称
5、$ksTwo文章二级栏目名称

if((!isset($_GET['act'])) || ($_GET['act']=="") || (!in_array($_GET['act'], $ksxxListArr))){

  }

/****************定义方法获取上下篇***************************/

if($arc['id'] !=""){
   include(dirname(__FILE__).'/templets/article.htm');
  }else{
   ShowMsg('非法请求，请勿修改参数！', '/');
   exit();
  }

注意：上下篇调用参考如下：
  
   <div class="prenext">
    <ul>
      <li><?php echo $PreNext['pre']; ?></li>
      <li><?php echo $PreNext['next']; ?></li>
    </ul>
   </div>
