dedecms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}  


函数代码,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.",%')";
