2 个解决方案

#1

specify the form action and add a submit button. upon submit, $_POST['sexo'] should contain your result (m or h)

指定表单操作并添加提交按钮。提交后,$ _POST ['sexo']应包含您的结果(m或h)

#2

This is not a recommended fix, but it will work:

这不是推荐的修复,但它可以工作:

Change:

 <form  method="POST">

To:

 <form action="#"  method="post">

NOTE: Technically method should be lower case. It's an XHTML requirement. You would be penalized by W3C mobileOK validation.

注意:技术方法应该是小写的。这是XHTML的要求。您将受到W3C mobileOK验证的惩罚。
