DEDECMS织梦调用得到文章所属的副栏目id及副栏目名称的教程

        <a  href="javascript:"onclick="javascript:change_tab([field:typeid/]);">[field:typename/]</a> 
        <!-- 上面是文章所属的主栏目,很方便调用. --> 
        [field:typeid2 function="get_url_by_typeid2(@me)"/] 
        <!-- 上面是文章所属的副栏目,需要单独写函数get_url_by_typeid2 -->

//得到副栏目信息,并组织字符串 
function get_url_by_typeid2($typeid2){ 
        $arrs=explode(",",$typeid2);//解析副栏目字段

//织梦根据栏目编号typeid调用typename栏目名
