DedeCMS用于图片站WEB开发时，需要随机调用文章、图集和关联文章、图集功能，以增加用户黏度，属于站内优化重要一部分。一般用标签调用都有排序orderby，默认的排序主要有
{dede:arclist orderby=''}
[field:title/]
{/dede:arclist}
orderby='sortrank' 文档排序方式
orderby='hot' 或 orderby='click' 表示按点击数排列
orderby='sortrank' 或 orderby='pubdate' 按出版时间排列
orderby='near'
orderby='lastpost' 按最后评论时间
orderby='scores' 按得分排序
orderby='id' 按文章ID排序
orderby='rand' 随机获得指定条件的文档列表
但{dede:likearticle}却没有orderby这个功能。下面是修改方法：
打开/include/taglib/likearticle.lib.php，找到
if( empty($arcid) || $byabs==0 ) {
$orderquery = " order by arc.id desc ";
}
else {
$orderquery = " order by ABS(arc.id - ".$arcid.") ";
}
修改为
if($orderby=='hot' || $orderby=='click') $orderquery = " order by arc.click $orderWay";
else if($orderby == 'sortrank' || $orderby=='pubdate') $orderquery = " orderby arc.sortrank $orderWay";
else if($orderby == 'id') $orderquery = " order by arc.id $orderWay";
else if($orderby == 'near') $orderquery = " order by ABS(arc.id - ".$arcid.")";
else if($orderby == 'lastpost') $orderquery = " order by arc.lastpost $orderWay";
else if($orderby == 'scores') $orderquery = " order by arc.scores $orderWay";
else if($orderby == 'rand') $orderquery = " order by rand()";
else if($orderby == 'weight') $orderquery = " order by arc.weight asc";
else $orderquery = " order by arc.sortrank $orderWay";
