dedecms如何显示tags标签数量

织梦cms子栏目获取父级栏目名称教程，下面是调用顶级栏目名称的详细代码方法，一起来学习吧：

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}这个方法语句有些长。

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(推荐)：

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']);}}使用方法同上。
