,子栏目调用父级栏目名称方法,下面是调用顶级栏目名称的方法：方法一：,1,2,3,4,5,6,7,{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 = $row[typename];}{/dede:field.typeid},这个方法语句有些长。,方法二：,1,2,3,{dede:field.title runphp='yes'},list($toptype,$sontype)=split('/',@me);@me=$toptype;,{/dede:field.title},方法三：,1,2,3,4,5,6,7,8,{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 = $row[typename];}{/dede:field.typeid},方法四（推荐）：,打开include/helpers/extend.helper.php，添加一个函数：,1,2,3,4,5,6,7,8,9,10,11,12,13,14,/**,* 获取指定栏目id的顶级栏目的名称,*,* @return string,*/,if ( ! function_exists('getTopChannelName')),{,function getTopChannelName($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：,1,2,3,4,5,6,7,8,9,10,11,12,13,14,/**,* 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']);,},},使用方法同上。
