问题在于你的脚本，如果你有两个单独的文件，它就不会工作。

（不是那么快Fred）... 它仍然有效，但它不会按预期工作，以便向您显示一个或多个字段的错误消息没有填写，是你的代码的全部目的。

它需要在一个文件中（首先是PHP，然后是你的HTML表单）旁注：顺序并不重要;选择是你的。此外，您还需要修改代码，使其包含有效的From:。 更多相关内容。

除此之外，我已经说过的内容必须是.php扩展名。

因此您需要更改此行：

$from = 'Demo Contact Form';

为：

$from = "From: ". $name . " <" . $email . ">\r\n";

为了在电子邮件中显示该人的姓名，但同时使用电子邮件地址作为＆＃34;来自：＆＃34;

否则，它看起来好像来自您自己的服务器，而不是来自此人的电子邮件。

（我已经为自己测试过了）
