dedecms子栏目如何调用父级栏目名称方法

方法一：

{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}

方法二：

{dede:field.title  runphp='yes'}
list($toptype,$sontype)=split('/',@me);@me=$toptype;
{/dede:field.title}

方法三：

{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]"; $topID="$row[topid]"; 
if($relID == 0) {@me = $row[typename];}
else{$sql = "SELECT `typename` FROM `dede_arctype` WHERE id=$topID";
$query = mysql_query($sql);$row=mysql_fetch_array($query); 
@me = $row[typename];}{/dede:field.typeid}

方法四：

打开include/helpers/extend.helper.php，添加一个函数：

/**
*  获取指定栏目id的顶级栏目的名称
*
* @return     string
*/
if ( ! function_exists('getTopChannelName'))
{
function getTopChannelName($id) {
global $dsql;
$typeinfo = $dsql->GetOne("SELECT * FROM `dede_arctype` WHERE id='{$id}'");
if($typeinfo['reid']==0) return $typeinfo['typename'];
else return getTopChannelName($typeinfo['reid']);
}
}

在列表页这么使用：{dede:field name='id' function='getTopChannelName(@me)'/}

在内容页这么使用：{dede:field name='typeid' function='getTopChannelName(@me)'/}

附带获取顶级栏目的url：

打开include/helpers/extend.helper.php，添加一个函数：

/**
*  获取指定栏目id的顶级栏目的url
*
* @return     string
*/
if ( ! function_exists('getTopChannelUrl'))
{
function getTopChannelUrl($id) {
global $dsql;
$typeinfo = $dsql->GetOne("SELECT * FROM `dede_arctype` WHERE id='{$id}'");
if($typeinfo['reid']==0) return GetOneTypeUrlA($typeinfo);
else return getTopChannelUrl($typeinfo['reid']);
}
}
