dedecms如何调用得到文章所属的副栏目id及副栏目名称

标签调用代码：

{
    dede: arclist row = '2'
    titlelen = '100'
    typeid = 2 orderby = 'id'
} < span > < 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 -->   

</span > {
        /dede:arclist}

在/include/extend.func.php中增加如下代码：

//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       

if($typeid2==0){           

return '';       }else{           
$url='';           
foreach($arrs as $v){               

$url.='<a href="javascript:"               

onclick="javascript:change_tab('.$v.');">'.get_typename($v).'</a>';           }       

return $url;       }   }   

//织梦根据栏目编号typeid调用typename栏目名   

function get_typename($typeid){       

global $dsql;       
$rs=$dsql->getOne("select typename from arctype where id='$typeid'");   

return $rs['typename'];   
}

注意：织梦标签artlist不能调用副栏目中的文章内容的问题，即文章属于互联网这个副栏目，但互联网栏目中却不显示这个文章。需要修改系统文件/include/taglib/arclist.lib.php

if($CrossID=='') $orwheres[] = ' arc.typeid IN ('.GetSonIds($typeid).')';  
else $orwheres[] = ' arc.typeid IN ('.GetSonIds($typeid).','.$CrossID.')';

修改为

if($CrossID=='')  
$orwheres[] = " (arc.typeid in (".GetSonIds($typeid).") or arc.typeid2 in (".GetSonIds($typeid).") or CONCAT( ',', arc.typeid2, ',' ) LIKE '%,".$typeid.",%' )";  
else  
$orwheres[] = " (arc.typeid in (".GetSonIds($typeid).",".$CrossID.") or arc.typeid2 in (".GetSonIds($typeid).",".$CrossID.") or CONCAT( ',', arc.typeid2, ',' ) LIKE '%,".$typeid.",%')";
