php forms email validation

Php 表单错误消息无法正常工作，表单无法提交,php,forms,email,validation,Php,Forms,Email,Validation,我对表单验证和处理非常陌生，事实上，这是我的第一次尝试，我创建了一个简单的联系人表单，其中包含必需的文本字段、注释文本区域和两个单选按钮。我已经完成了许多基本的教程，并使用PHP编写了脚本。我遇到的问题是，如果表单未填写，当我单击“提交”时，我会被引导到一个新页面，其中有一条错误消息，说我需要填写我的姓名。但是，如果我填写我的姓名并单击submit，我会收到相同的消息，而不是为下一个字段指定的错误消息。当所有字段都归档时，我甚至收到了这个消息。这是我的密码： <?php $

总是正确的-这让我觉得你在$\u POST['name']
中没有任何价值-放一些消息，看看你有什么信息。
