在DEDE根目录/include/taglib/下找到channel.lib.php文件找到
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, $line ";
}
然后，在此段代码下加入如下代码，为{dede：channel}添加父级(parent)栏目属性
else if($type=='parent')
{
$sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath
From `dede_arctype` where id='$reid' AND ishidden<>1 order by sortrank asc limit 0, $line ";
}
然后用下面的就行了
<!--调用当前栏目的顶级栏目名称-->
{dede:channel type='parent' }
[field:typename/]
{/dede:channel}
dede 子栏目获取上级、顶级栏目的名字和链接
上面的方法当 当前栏目就是顶级栏目时候会失效，所以需要用到下面的方法【非无限子栏目】
{dede:field.typeid runphp='yes'}$ID = @me; $sql = "SELECT * FROM `dede_arctype` WHERE id=$ID";$query = mysql_query($sql);$row=mysql_fetch_array($query); $relID = "$row[reid]"; if($relID == 0) {@me = $row[typename];}else{$sql = "SELECT `typename` FROM `dede_arctype` WHERE id=$relID";$query = mysql_query($sql);$row=mysql_fetch_array($query); @me = $row[typename];}{/dede:field.typeid}
下面是顶级栏目的ID【非无限子栏目】
{dede:field.typeid runphp='yes'}$ID = @me; $sql = "SELECT * FROM `dede_arctype` WHERE id=$ID";$query = mysql_query($sql);$row=mysql_fetch_array($query); $relID = "$row[reid]"; if($relID == 0) {@me = $row[id];}else{$sql = "SELECT `id` FROM `dede_arctype` WHERE id=$relID";$query = mysql_query($sql);$row=mysql_fetch_array($query); @me = $row[id];}{/dede:field.typeid}
下面是无限子栏目获取顶级栏目资料的方法，不过下面的实例是获取顶级栏目下，的第二个栏目的方法，不过要获取顶级栏目的话，更简单，所做修改即可。
{dede:field.typeid runphp='yes'}
$ID = @me;
$sql = "SELECT * FROM `dede_arctype` WHERE id=$ID";
$query = mysql_query($sql);
$row=mysql_fetch_array($query);
$relID = $row[reid];
$jishu;
while($relID != 0){
$jishu = $row[id];
$sql = "SELECT * FROM `dede_arctype` WHERE id=$relID";
$query = mysql_query($sql);
$row=mysql_fetch_array($query);
$relID = $row[reid];
}
$sql = "SELECT * FROM `dede_arctype` WHERE id=$jishu";
$query = mysql_query($sql);
$row=mysql_fetch_array($query);
@me = $row[arcpic];
{/dede:field.typeid}
