我已经在顶部提供了预标签，以便我可以看到什么值正在进行，当我点击ragister按钮时，所有值都是正确的，除了业余爱好，因为它给予“在“为什么这样，请让我知道，我是新来的PHP，请尽可能详细地解释我。问题在业余爱好，因为无法使用PHP获取选定的值

感谢名单，@Jamkelvl ......还有一两件事是有没有其他简单的方法验证在“性别”作为我”米无法理解这....在我的代码 – Shanky
此链接显示一个类似于你的形式和讨论验证。也许这会有所帮助。 [PHP表单验证]（http://www.w3schools.com/php/php_form_validation.asp） – lovermanthing
您是否试图验证性别单选按钮是否已被选中？如果是这样，它看起来像你试图从jQuery推到一个PHP数组，这是不可能的。 PHP是服务器端语言，jQuery是客户端。如果你想覆盖那些没有启用javascript的用户，你只需要用jQuery或者PHP或者两者都进行验证。 –
