<div class="tabs">[e:loop={"select classid,classname from {$dbtbpre}enewsclass where classid in($public_r[add_zhann_home_classid1]) order by myorder,classid asc",0,24,0}]<?php$style = ''; if($bqno==1) $style="active";?> <div class="tab <?=$style?>"><?=$bqr[classname]?></div>[/e:loop]              </div>

解释:获取扩展变量add_zhann_home_classid1扩展变量里的栏目ID

if($bqno==1) $style="active";

如果是第一个,样式为active
