<p>
一、打开include/taglib/目录下的 tag.lib.php 文件</p>
<p>
找到下面这段代码，并在中间插入标注部分代码，（红色）</p>
<blockquote>
<ol class="dp-c">
<li class="alt">
<span><span>(</span><span class="vars">$getall</span><span>==0 && isset(</span><span class="vars">$refObj</span><span>->Fields[</span><span class="string">'tags'</span><span>]) && !</span><span class="func">empty</span><span class="keyword">empty</span><span>(</span><span class="vars">$refObj</span><span>->Fields[</span><span class="string">'aid'</span><span>])) </span></span>
</li>
<li>
<span>{ </span>
</li>
<li class="alt">
<span><span class="vars">$dsql</span><span>->SetQuery(</span><span class="string">"Select tid From `ddmx_taglist` where aid = '{$refObj->Fields['aid']}' "</span><span>); </span></span>
</li>
<li>
<span><span class="vars">$dsql</span><span>->Execute(); </span></span>
</li>
<li class="alt">
<span><span class="vars">$ids</span><span> = </span><span class="string">''</span><span>; </span></span>
</li>
<li>
<span><span class="keyword">while</span><span>(</span><span class="vars">$row</span><span> = </span><span class="vars">$dsql</span><span>->GetArray()) </span></span>
</li>
<li class="alt">
<span>{ </span>
</li>
<li>
<span><span class="vars">$ids</span><span> .= ( </span><span class="vars">$ids</span><span>==</span><span class="string">''</span><span> ? </span><span class="vars">$row</span><span>[</span><span class="string">'tid'</span><span>] : </span><span class="string">','</span><span>.</span><span class="vars">$row</span><span>[</span><span class="string">'tid'</span><span>] ); </span></span>
</li>
<li class="alt">
<span>} </span>
</li>
<li>
<span><span class="keyword">if</span><span>(</span><span class="vars">$ids</span><span> != </span><span class="string">''</span><span>) </span></span>
</li>
<li class="alt">
<span>{ </span>
</li>
<li>
<span><span class="vars">$addsql</span><span> = </span><span class="string">" where id in($ids) "</span><span>; </span></span>
</li>
<li class="alt">
<span>} </span>
</li>
<li>
<span><span class="keyword">if</span><span>(</span><span class="vars">$addsql</span><span>==</span><span class="string">''</span><span>) </span><span class="keyword">return</span><span> </span><span class="string">''</span><span>; </span></span>
</li>
<li class="alt">
<span>} </span>
</li>
<li>
<span><span><span class="comment">//自定义添加标签</span><span> </span></span></span>
</li>
<li class="alt">
<span><span><span class="keyword">else</span><span> </span><span class="keyword">if</span><span>(</span><span class="vars">$getall</span><span>==2) </span></span></span>
</li>
<li>
<span><span>{ </span></span>
</li>
<li class="alt">
<span><span><span class="vars">$addsql</span><span> = </span><span class="string">" where typeid='{$refObj->Fields['typeid']}' "</span><span>; </span></span></span>
</li>
<li>
<span><span>} </span></span>
</li>
<li class="alt">
<span><span><span class="comment">//自定义添加标签结束</span><span> </span></span></span>
</li>
<li>
<span><span class="keyword">else</span><span> </span></span>
</li>
<li class="alt">
<span>{ </span>
</li>
<li>
<span><span class="keyword">if</span><span>(!</span><span class="func">empty</span><span class="keyword">empty</span><span>(</span><span class="vars">$typeid</span><span>)) </span></span>
</li>
<li class="alt">
<span>{ </span>
</li>
<li>
<span><span class="vars">$addsql</span><span> = </span><span class="string">" where typeid='$typeid' "</span><span>; </span></span>
</li>
<li class="alt">
<span>} </span>
</li>
</ol>
</blockquote>
<p>
二、修改你的模板</p>
<p>
模板调用如下：</p>
<blockquote>
<ol class="dp-xml">
<li class="alt">
<span><span>{</span><span class="attribute">dede:tagsort</span><span>='hot'</span><span class="attribute-value">getall</span><span>='2'} </span></span>
</li>
<li>
<span> </span>
</li>
<li class="alt">
<span><span class="tag"><</span><span class="tag-name">a</span><span> </span><span class="attribute">href</span><span>=</span><span class="attribute-value">''</span><span class="tag">></span><span></span><span class="tag"></</span><span class="tag-name">a</span><span class="tag">></span><span> </span></span>
</li>
<li>
<span> </span>
</li>
<li class="alt">
<span>{/dede:tag} </span>
</li>
</ol>
</blockquote>
<p>
这样就能更完美的根据自己的需要来定制要显示的内容了。</p>
