调用代码

{dede:liketags row='3' typeid='6' titlelen='250' eregtype='all|tag|keyword' flag='c' infolen='250'}
<li>
<a href="[field:arcurl/]" title="[field:title/]" target="_blank">
<div class="list-img">
<img src="[field:litpic/]" alt="[field:title/]"/>
</div>
<div class="list-info">
<p class="title">[field:title/]</p>
<p class="meta">¥[field:jiage /]元</p>
</div>
</a>
</li>
{/dede:liketags}

typeid的= '6'可指定栏目

flag ='c'可指定文章属性调用,例如推荐[c]头条[h]

¥[field:jiage /]元自定义字段直接写即可,不需要像dede:arclist那样加channelid =''addfields =''
