thinkPHP连表问题，大家进来看看，谢谢了。

join('__COUNTS__ ON __CHOICES__.id = __COUNTS__.cid AND __CHOICES__.vid = __COUNTS__.vid')->order($order)->select();是什么意思，我看不懂，求解释，谢谢了。

回复讨论(解决方案)

相当这样
... inner join counts on choice.id = counts.cid and choices.vid = counts.vid order by $order;
__COUNTS__ 若是有设置表前缀的话，会自动加上 如 t_ 那么 __COUNTS__ 解析后就是 t_counts
