仅包含电子邮件字段的PHP表单赢得'；t发送，而完整的表单工作正常

所以我设法得到了一个包含姓名、电子邮件和消息的表单，现在我正试图制作另一个表单，以实现某种“敬请关注”的功能，但我无法让它在我的一生中发挥作用。我希望有人能指出（可能）明显的错误

同一页面中的2个字段应具有相同的名称和id。 尝试为表单操作属性提供完整的url，即使用站点url ex site\u url/页面

注意：您的代码不安全。 注意2：您应该为每个表单的“提交”按钮指定不同的名称，并且应该使用if（）确定是否单击了该按钮。

这应该有效。

两个表单都在同一页中？是的，它们链接到两个不同的PHP文件。第2个字段在同一页中应该有相同的名称和id。更改一个字段名称并尝试它将起作用。我将更改为其他名称并在PHP中进行了更改，但当我按提交按钮时仍然没有发生任何事情。尝试在表单操作属性中提供完整url我尝试了一下，但电子邮件表单仍然没有任何作用。此外，完整表单现在只显示传入电子邮件中提交的名称，而email:和message:字段保持为空。我发现两个php文件都有语法错误，我不知道如何修复它。只需在两个回音“”的末尾添加分号（；）；
