帝国cms是一款非常优秀的内容管理系统，它可以帮助我们快速地建立一个网站。在网站建设过程中，我们经常需要调用二级栏目来展示网站内容。本文将介绍如何在帝国cms中调用二级栏目。
一、创建二级栏目
在帝国cms中，创建二级栏目非常简单。首先，我们需要在后台管理系统中找到“栏目管理”选项，然后点击“添加栏目”按钮。在弹出的对话框中，我们可以填写二级栏目的名称、链接地址、栏目类型等信息。更后，点击“确定”按钮即可创建二级栏目。
二、调用二级栏目
在帝国cms中，调用二级栏目也非常简单。我们只需要在需要展示二级栏目的页面中添加如下代码：
<?php
$sortid = $GLOBALS['sortid'];
$sort = $GLOBALS['sort'];
$secondsort = $sort['son'][$sortid]['son'];
foreach($secondsort as $k=>$v){
$secondsort[$k]['url'] = $GLOBALS['cfg_basehost'] . $v['url'];
}
?>
上述代码会自动调用当前页面的二级栏目，并将二级栏目的信息存储在$secondsort数组中。我们可以通过遍历$secondsort数组来展示二级栏目的信息。
三、帝国cms图集调用
在帝国cms中，我们经常需要调用图集来展示网站内容。下面是一个简单的帝国cms图集调用示例：
<?php
$aid = $aid ? $aid : $GLOBALS['aid'];
$arc = GetOneArchive($aid);
if($arc['channel'] == 1){
$dtp = new DwtTagParse();
$dtp->LoadTemplate($cfg_basedir . $cfg_templets_dir . $arc['tempid'] . '.htm');
$dtp->Assign('title', $arc['title']);
$dtp->Assign('litpic', $arc['litpic']);
$dtp->Assign('description', $arc['description']);
$dtp->Assign('pubdate', GetDateMk($arc['pubdate']));
$dtp->Assign('click', $arc['click']);
$dtp->Assign('body', $arc['body']);

$dtp->Assign('tags', GetTags($aid));
$dtp->Assign('prev', GetPreNext($aid, $arc['typeid'], 0));
