wap/index.php
 
if (!empty($_GET["action"]))
$action=$_GET["action"];
else
$action="home";
//$action=empty($action)?"home":$_GET["action"];
//===============================
if(in_array($action, array('home','offer_cat','offer_list','offer_detail','product_cat','product_list','product_detail','news_cat','news_list','news_detail','corporate_cat','corporate_list','corporate_detail','search','corporate_moredetail','product_showimg')))
{
        require'inc/'.$action.'.php';
}news_cat.php文件
 
if(!empty($_GET['nid']))
{
        $nid=$_GET['nid'];
    $sql="select * from ".NEWSCAT." where pid=$nid";
    $db->query($sql);
    $sre=$db->getRows();
        if(count($sre)>0)
        {
                foreach($sre as $v)
                {
                        echo "[资讯]<a href='?action=news_list&newsid=".$v['catid']."'>".$v['cat']."</a>";
                }
                echo "      <a href='?action=news_cat'><i>返回</i></a>";
                //echo "  <anchor>后退<prev/></anchor>";
        }
        else
        {
                header("Location:./?action=news_list&nid=".$nid);
        exit();
        }
}随便一条错误的语句即可得到数据库前缀
