在include/common.func.php的最下方加入：</p>
<div class="jb51code" style='margin: 0px; padding: 0px; outline: none; line-height: 25.2px; font-size: 14px; width: 660px; overflow: hidden; clear: both; font-family: tahoma, arial, "Microsoft YaHei";'>
<pre class="brush:php;toolbar:false;">

global $dsql;
$row = $dsql->GetOne("SELECT typename,topid FROM dede_arctype WHERE id= $id");
if ($row['topid'] == '0')
{
return $row['typename'];
}
else
{
$row1 = $dsql->GetOne("SELECT typename FROM dede_arctype WHERE id= $row");
return $row1['typename'];
}
}

在文章页或者栏目列表页调用时，在所要调用 名称的位置加上下面这行代码即可实现。</p>
<div class="jb51code" style='margin: 0px; padding: 0px; outline: none; line-height: 25.2px; font-size: 14px; width: 660px; overflow: hidden; clear: both; font-family: tahoma, arial, "Microsoft YaHei";'>

dedecms获取顶级栏目名称、二级栏目名称实现方法</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
今天做站的时候碰到一个问题，需要在二级、三级，甚至更多级，获取顶级栏目或者二级栏目名称。</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
现在和大家分享下最简单的实现方法。找到include/common.func.php文件，在里面加入下面这段代码：</p>
<div class="jb51code" style='margin: 0px; padding: 0px; outline: none; line-height: 25.2px; font-size: 14px; width: 660px; overflow: hidden; clear: both; font-family: tahoma, arial, "Microsoft YaHei";'>
<pre class="brush:php;toolbar:false;">
//获取二级栏目名
function GetTopTypename($id)
{
global $dsql;
$row = $dsql->GetOne("SELECT typename,reid FROM gsh_arctype WHERE id= $id");
if ($row['reid'] == '0')
{
return $row['typename'];
}
else
{
$row2 = $dsql->GetOne("SELECT typename FROM gsh_arctype WHERE id= $row");
return $row2['typename'];
}
}</pre>
</div>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
然后在任意列表页、内容页需要调用名称的地方加入：</p>
<div class="jb51code" style='margin: 0px; padding: 0px; outline: none; line-height: 25.2px; font-size: 14px; width: 660px; overflow: hidden; clear: both; font-family: tahoma, arial, "Microsoft YaHei";'>
<pre class="brush:xml;toolbar:false;">
{dede:field.typeid fuction="GetToypename(@me)"/}</pre>
</div>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
如果在dede标签里面，就用下面这句调用：</p>
<div class="jb51code" style='margin: 0px; padding: 0px; outline: none; line-height: 25.2px; font-size: 14px; width: 660px; overflow: hidden; clear: both; font-family: tahoma, arial, "Microsoft YaHei";'>
<pre class="brush:php;toolbar:false;">
</pre>
</div>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
上面这个方法是调用栏目的二级栏目名称，如果需要顶级栏目名称，只要将SQL里面的reid字段改成topid就可以了。另外记得将gsh_arctype前缀改成你数据库的前缀。</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
