帝国cms内容页输出当前信息所属专题及专题下信息

做了个模板，用到专题输出判断，具体逻辑如下：

内容模板中分两段判断，

1、当前信息如果有所属专题，则输出当前内容页所属专题

2、如果以上条件不满足，则输出默认专题

代码附上（参考sy12）：

<?php
$classname = $class_r[$navinfor['classid']]['classname'];
?>

                <div class="detailCont_left5">
            <p class="csTlt_1 csTlt_2"><span>相关专题</span><a href="/zt/" rel="external nofollow"  class="more" target="_blank" title=""><em>更多</em><i class="icon"></i></a></p>
            <div class="tabBar">
