V9显示哪些栏目的方法
{loop subcat(0,0,0,$siteid) $r}
{if
$r[‘catid‘]==1||$r[‘catid‘]==2 } //显示哪些栏目
{php $num++}
<div class="box cat-area" {if
$num%2!=0}style=" margin-right:10px"{/if}>
<h5 class="title-1">{$r}<a
href="{$r}" class="more">更多>></a></h5>
<div
class="content">
{pc:content action="lists"
catid="$r" order="updatetime DESC" thumb="1" num="1" return="info"}
{loop
$info $v}
<p>
<img
src="{thumb($v,90,0)}" width="90" height="60"/>
<strong><a target="_blank"
title="{$v[‘title‘]}"{title_style($v)}>{str_cut($v[‘title‘],28)}</a></strong><br />{str_cut($v[‘description‘],100)}
</p>
{/loop}
{/pc}
<div
class="bk15 hr"></div>
{pc:content
