模板标签里面
内容页判断tag相关的内容大于等于1条显示内容，不然不显示
{if $_.tag >= 1}<div class="xiangguan">
<div class="tit">
<span class="name">{$keywords}</span>
<span class="size">状态</span>
<span class="lang">格式</span>
<span class="time">更新时间</span>

{related module=MOD_DIR tag=$tag NOT_id=$id num=1000} {/related} 判断查询内容的数量大于1条才显示 {if $count >= 1}<div class="xiangguan"> <div class="tit"> <span class="name">{$keywords}</span> <span class="size">状态</span> <span class="lang">格式</span> <span class="time">更新时间</span> </div> {related module=MOD_DIR tag=$tag NOT_id=$id num=1000} <dl{if $key%2==1} class="line"{/if}> <dt class="name"><a class="type" target="_blank" href="{dr_cat_value('book',$t.catid,'url')}" target="_blank">[{dr_cat_value('book',$t.catid,'name')}]</a><a class="title" target="_blank" href="{$t.url}" target="_blank">{dr_strcut($t.title,20)}</a><em>{$t.tags}</em></dt> <dd class="size">{$t.version}</dd> <dd class="lang">TXT</dd> <dd class="time">{date('Y-m-d',$t._updatetime)}</dd> </dl> {/related} </div>{else}11111111111111{/if}
