织梦dedecms获取当前栏目的上级栏目的方法:
{dede:field name='typeid' runphp='yes'}

global $dsql;

$typeid = @me;
$query = "SELECt reid FROM dede_arctype where id = $typeid";
$rs = $dsql->GetOne($query);
$reid = $rs['reid'];//获取到栏目的上级栏目

$query2 = "SELECt * FROM dede_arctype where id = $reid";
$row = $dsql->GetOne($query2);

$typename = $row['typename'];
$link = GetTypeUrl($row['typeid'],MfTypedir($row['typedir']),$row['isdefault'],$row['defaultname'],$row['ispart'],$row['namerule2'],$row['moresite'],$row['siteurl'],$row['sitepath']);
@me = "<a href='{$link}'>{$typename}</a>";//这里面的这个A标签可以随意加代码,比如"<li><a href='{$link}'>{$typename}</a></li>"
