                • 之前写过一篇文章《DEDECMS织梦栏目和内容页调用相关文章》

                  今天在记录一篇织梦文章tag标签或者文章keyword关键字调用相关文章 


                  摘要:官方的dede:likearticle并没有那么精准的输出相关文章,下面我们自定义一个类库文件来实现精准获取相关文章 单用tag来调用相关文章,也可用tag+keyword来调用相关文章(默认tag优先于keyword,可以自己排序)非常适合SEO

                  前台模板标签调用写法

                  {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='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=''
