DedeCMS内容页添加＂相关文章＂功能

在DedeCms文章内容页底部加入一个"相关文章"的栏位，不但可以去除DEDECMS默认模版原有的生硬，增加美观，而且对SEO和提升网站PV也有很大的帮助，要想实现这个功能很容易，利用现成的likearticle标签即可。实现方法如下："

1.进入DedeCms网站管理后台，打开文章内容页模版article_article.htm，如下图：

2.找到以下代码：

<br> <span class="sh_symbol"><span style="font-size:12px;"><!--</span></span><span class="sh_normal"> </span><span class="sh_symbol"><span style="font-size:12px;">/</span></span><span style="font-size:12px;">handle </span><span class="sh_symbol"><span style="font-size:12px;">--></span></span><br><span class="sh_symbol"><span style="font-size:12px;"></</span></span><span style="font-size:12px;">div</span><span class="sh_symbol"><span style="font-size:12px;">></span></span><br><span class="sh_symbol"><span style="font-size:12px;"><!--</span></span><span class="sh_normal"> </span><span class="sh_symbol"><span style="font-size:12px;">/</span></span><span style="font-size:12px;">viewbox </span><span class="sh_symbol"><span style="font-size:12px;">--></span></span><br> <span class="sh_symbol"><span style="font-size:12px;"><!--</span></span> <span class="sh_comment"><span style="font-size:12px;">//AJAX评论区 --></span></span><br><span class="sh_cbracket"><span style="font-size:12px;">{</span></span><span style="font-size:12px;">dede</span><span class="sh_symbol"><span style="font-size:12px;">:</span></span><span style="font-size:12px;">include file</span><span class="sh_symbol"><span style="font-size:12px;">=</span></span><span class="sh_string"><span style="font-size:12px;">'ajaxfeedback.htm'</span></span> <span class="sh_regexp"><span style="font-size:12px;">/} </</span></span><span style="font-size:12px;">div</span><span class="sh_symbol"><span style="font-size:12px;">></span></span><br><span class="sh_symbol"><span style="font-size:12px;"><!--</span></span> <span class="sh_comment"><span style="font-size:12px;">//左边内容结束 --></span></span>

3.在 和 之间插入代码，效果如下：

<span class="sh_symbol"><span style="font-size:12px;"><!--</span></span><span class="sh_normal"> </span><span class="sh_symbol"><span style="font-size:12px;">/</span></span><span

　 　但是，likearticle标签调用的相关文章是取自当前栏目的，这就局限了我们在SEO方面的应用，根据网站整体的SEO策略有时候我们需要从全站 库里调取相关文章，因为这样做，既可以确保内容页面中内链相关度，又可以实现跨栏目的内链接，实现这个功能同样很简单，只需修改很少的代码；当然，它会带 来一个问题：要么从当前栏目中调用相关文章，要么从所有栏目里调用相关文章，二者只能选其一；如果可能那能定义新标签，为每个栏目定义差异化的调用方式， 效果会更好。具体的代码修改如下：

4.打开文件：\include\taglib\likearticle.lib.php，

　　找到代码：

<br><span style="font-size:12px;">$typeid </span><span class="sh_symbol"><span style="font-size:12px;">=</span></span> <span class="sh_string"><span style="font-size:12px;">" And arc.typeid in($typeid) And arc.id<>$arcid "</span></span><span class="sh_symbol"><span style="font-size:12px;">;</span></span><span style="font-size:12px;"> </span>

　　修改为：

<br><span style="font-size:12px;">$typeid </span><span class="sh_symbol"><span style="font-size:12px;">=</span></span> <span class="sh_string"><span style="font-size:12px;">" And arc.id<>$arcid "</span></span><span class="sh_symbol"><span style="font-size:12px;">;</span></span>

最后保存后更新htm文档就可以了。
