如果您放弃完整的代码，并希望我们能够为您解决问题，甚至不必说出问题，您将永远得不到任何帮助。 – 2010-03-17 09:11:32

您需要使用$_GET['flag_num']获得查询参数，而不是$flag_num。该脚本没有做任何事情，因为没有任何变量具有任何价值。同样，$_GET['max_num'],$_GET['min_num']，$_GET['hid_num']。

仍然无法正常工作..我想我应该使HTML然后使用它的帮助下get method.is它？ – user216112 2010-03-17 13:56:48

这将有助于了解您遇到的问题，只是说它不起作用不够好。 – 2010-03-17 14:22:18
