<?PHP print_r(变量);?>
1.
<div class="webnav"> {pc:get sql="select catname,url from v9_category order by listorder ASC" } <ul class="clearfix"> <!--<li><a href="{siteurl($siteid)}">首页</a></li>--> {loop @H_403_24@$data @H_403_24@$r} <li><a href="{@H_403_24@$r[url]}">{@H_403_24@$r[catname]}</a></li> {/loop} </ul> {/pc} {PHP echo runhook('glogal_menu')} </div>
加粗的写法：从栏目表查出catname 和 url字段值 按照listorder 正序排列
{pc:get sql="select catname,url from v9_category order by listorder ASC" } 可以改写成
{pc:get sql="select*from v9_category order by listorder ASC" }
2.导航选中状态：
例如：
<div {pc:get sql="select * from v9_category order by listorder ASC"class="clearfix"> {$catid} <li><a href="{siteurl(@H_403_24@$siteid)}">首页</a></li>else} <li class="current"><a href="{siteurl(@H_403_24@ {/if} {loop @H_403_24@} <li {$catid==@H_403_24@if}><a href="{@H_403_24@loop} </ul>pc} {PHP )} </div>
当然首页那也可以这样：
$catid //当前栏目ID
$r['catid'] //循环出来的
