dede获取顶级栏目名称

做网站在二级页面需要 获得 从一级页面点进来的链接 的 顶级栏目名称，但dede给的标签貌似只能获得一串名称(顶级/二级/某链接)这样的，所以上网查了一些资料，找到个比较靠谱的。

1、新建一个文件叫 parentchannel.lib.php

<?php

/**

* 父栏目调用标签

*

* @version $Id: parentchannel.lib.php 1 9:29 2010年7月6日Z tianya $

* @package DedeCMS.Taglib

* @copyright Copyright (c) 2007 - 2010, DesDev, Inc.

* @license http://help.dedecms.com/usersguide/license.html

/*>>dede>>

function lib_parentchannel(&$ctag,&$refObj)

{

global $_sys_globals,$dsql;


$attlist = "row|100,nosonmsg|,col|1";

FillAttsDefault($ctag->CAttribute->Items,$attlist);

extract($ctag->CAttribute->Items, EXTR_SKIP);

$innertext = $ctag->GetInnerText();

 

$reid = 0;

$topid = 0;

//如果属性里没指定栏目id，从引用类里获取栏目信息

if(empty($typeid))

{

if( isset($refObj->TypeLink->TypeInfos['id']) )

{

$typeid = $refObj->TypeLink->TypeInfos['id'];

$reid = $refObj->TypeLink->TypeInfos['reid'];

$topid = $refObj->TypeLink->TypeInfos['topid'];

}

else {

$typeid = 0;

}

} //如果指定了栏目id，从数据库获取栏目信息

else

{

}


$sql = "SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath

FROM `#@__arctype` WHERE reid='$typeid' AND ishidden<>1 ORDER BY sortrank ASC LIMIT 1";

$dsql->SetQuery($sql);

if($totalRow==0){

if(!is_array($row)) return '';

}

if(trim($innertext)=='') $innertext = GetSysTemplets("part_type_list.htm");


$dtp = new DedeTagParse();

$dtp->SetNameSpace('field','[',']');

$dtp->LoadSource($innertext);

if(!is_array($dtp->CTags))

{

unset($dtp);

return '';

}

else

{

$row['typelink'] = $row['typeurl'] = GetOneTypeUrlA($row);

foreach($dtp->CTags as $tagid=>$ctag)

{

if(isset($row[$ctag->GetName()])) $dtp->Assign($tagid,$row[$ctag->GetName()]);

}

$revalue = $dtp->GetResult();

unset($dtp);

return $revalue;

}

}

?>

放到\include\taglib下

2、{dede:parentchannel}[field:typename/]{/dede:parentchannel}调用

OK!
