让织梦likearticle标签支持orderby的办法

if( empty($arcid) || $byabs==0 ) {
   $orderquery = " order by arc.id desc ";
}
else {
   $orderquery = " order by ABS(arc.id – ".$arcid.") ";
}

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";//如果没有特定设置排序则按照权重先排序
else $orderquery = " order by arc.sortrank $orderWay";
