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 = $row[typename];}{/dede:field.typeid}
复制代码 这个方法语句有些长。
方法二:
- {dede:field.title runphp='yes'}
- list($toptype,$sontype)=split('/',@me);@me=$toptype;
- {/dede:field.title}
复制代码
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 = $row[typename];}{/dede:field.typeid}
复制代码
方法四(推荐):
打开include/helpers/extend.helper.php,添加一个函数:
- <span style="background-color: rgb(255, 255, 255);">/</span>**
- * 获取指定栏目id的顶级栏目的名称
- *
- * @return string
- */
- if ( ! function_exists('getTopChannelName'))
- {
- function getTopChannelName($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']);
- }
- }
复制代码
在列表页这么使用:
- {dede:field name='id' function='getTopChannelName(@me)'/}
复制代码
在内容页这么使用:
- {dede:field name='typeid' function='getTopChannelName(@me)'/}
复制代码
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']);
- }
- }
复制代码
使用方法同上。
