用php联系表格回复地址

Question

我买了一个简单的网站模板与php联系表格.实际接收通过表单发送的消息的一个小例外,一切都很好.也就是说,联系表单会显示成功消息,但消息永远不会到达.

经过我的托管服务的漫长反复,我发现为了避免欺骗,他们不允许在他们不主持的FROM地址发送电子邮件.也就是说,如果该网站的访问者在表单中写下他的gmail/yahoo等,我将无法得到它.

他们建议使用托管在其中的电子邮件地址作为FROM地址,并将访问者的输入电子邮件作为REPLY-TO地址.这看似合理.

所以我挖了一下(例如这里: PHP回复错误 - 附带管理员电子邮件而非联系表格的发件人 和 网站上的php联系表格以及回复电子邮件)

并且答案提示添加标题组件:

$headers = 'From: webmaster@example.com' . "\r\n" .
    'Reply-To: webmaster@example.com' . "\r\n" .
    'X-Mailer: PHP/' . phpversion();

并将其添加到

mail($to, $subject, $message, $headers);

这就是我做的.$ email在此模板中定义为访问者的电子邮件,因此我所做的是:

$subject = "Contact Form: $name";
$message = "$message";
$headers = 'From: myemail@my_domain.com' . "\r\n" .
    'Reply-To: $email' . "\r\n" .
    'X-Mailer: PHP/' . phpversion();

mail($to, $subject, $message, $headers);

这一切都很好,花花公子,但它仍然不能很好地工作.电子邮件现在通过,但细节是:

from:    myemail@my_domain.com via servername.hosting_company.com 
**reply-to:  $email@servername.hosting_company.com**
to:  myemail@my_domain.com

所以,回复地址仍然不是访客留下的.

你能帮帮我吗？不知道我还能做些什么.

非常感谢!

如果有人有兴趣,这里是完整的PHP文件:

foreach($_POST as $key => $value) {
    if(ini_get('magic_quotes_gpc'))
        $_POST[$key] = stripslashes($_POST[$key]);

$name = $_POST["name"];
$email = $_POST["email"];
$message = $_POST["message"];

// Test input values for errors
$errors = array();

Answer 1

尝试更改代码的这一部分:

$subject = "Contact Form: $name";
$message = "$message";
$headers = 'From: myemail@my_domain.com' . "\r\n" .
    'Reply-To: $email' . "\r\n" .
    'X-Mailer: PHP/' . phpversion();

对此:

$subject = "Contact Form: $name";
$message = "$message";
$headers = 'From: myemail@my_domain.com' . "\r\n" .
    'Reply-To: ' . $email . "\r\n" .
    'X-Mailer: PHP/' . phpversion();

基本上从单引号中取出$ email并将其附加到该字符串
