织梦arclist标签idlist按指定id顺序输出

1、打开 /include/taglib/arclist.lib.php 找到，大概在第338行

else if($orderby == 'rand') $ordersql = "  ORDER BY rand()";

在它下面加入一行

else if($orderby == 'idlist') $ordersql = "  ORDER BY FIELD(arc.id,$idlist)";

2、dede:arclist idlist='' 标签里加入orderby='idlist'

例如

{dede:arclist idlist='1,2,4,6,10'?orderby='idlist'}
<li><a href="[field:arcurl/]">[field:id/] - [field:title/]</a></li>
{/dede:arclist}
