织梦调用父级栏目链接和名称

最近因为网站开发，子栏目首页需要调用当前子栏目的顶级栏目名称和链接，打开文件

/include/taglib/channel.lib.php  

找到代码

else if($type=='self')  
{  
    if($reid==0) return '';  
    $sql = "SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath  
        FROM `dede_arctype` WHERE reid='$reid' And ishidden<>1 order by sortrank asc limit 0, $line ";  
}

在其后添加

else if($type=='topone')  
{  
if($reid==0) return '';  
$rowR = $dsql->GetOne("SELECT * FROM `dede_arctype` WHERE id='$typeid' ");  
$topids = $rowR['topid'];  
$sql = "SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath  
FROM `dede_arctype` WHERE reid='0' And id='$topids' And ishidden<>1 order by sortrank asc limit 0, $line ";  
}  
else if($type=='fatherlist')  
{  
$rowR = $dsql->GetOne("SELECT * FROM `dede_arctype` WHERE id='$typeid' ");  
$reid = $rowR['reid'];  
$rowR = $dsql->GetOne("SELECT * FROM `dede_arctype` WHERE id='$reid' ");  
$reid = $rowR['reid'];  
$sql = "SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath  
FROM `dede_arctype` WHERE reid='$reid' And ishidden<>1 order by sortrank asc limit 0, $line ";  
}

然后就可以在模板中调用父级栏目和父级顶级栏目了：

{dede:channel type='topone'}[field:typename/][field:typeurl/][field:id/]{/dede:channel}
