织梦DedeCms5.7全站按TAG和关键字调用相关文章方法，可单用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，经测试效果极佳。
1.把下边代码保存到文章模版的适当位置
<div class="xgwz"> <dl class="tbox"> <dt><strong>相关文章</strong></dt> <dd> <ul class="c1 ico2"> {dede:likearticle col='2' row='10' titlelen='42' eregtype=all|tag|keyword} <li><a href="[field:arcurl/]">[field:title/]</a></li> {/dede:likearticle} </ul> </dd> </dl> </div>
2.把下边的php代码替换掉include/taglib/likearticle.lib里的代码
