以php联系表格回复地址 [英] reply-to address in php contact form
问题描述
在我的托管服务经过漫长的回落之后,我发现在为了避免欺骗,他们不会允许邮件发送到他们不承载的FROM地址。也就是说,如果网站的访问者以表单的形式写下了他的Gmail /雅虎等,我将不会得到它。
他们建议使用托管的电子邮件地址将其作为FROM地址,并将访客的输入电子邮件作为REPLY-TO地址。这似乎是合理的。
所以我挖了(例如这里:
PHP回复错误 - 管理员电子邮件不是联系表单的发件人
和
php联系表格在网站和回复 - 电子邮件)
,答案建议添加标题组件:
$ headers ='From:webmaster@example.com'。 \\\\。
'Reply-To:webmaster@example.com'。 \\\\。
'X-Mailer:PHP /'。 phpversion();
,并将其添加到
mail($ to,$ subject,$ message,$ headers);
所以这就是我做的。
$ email在这个模板中定义为访客的电子邮件,所以我做的是:
$ subject = 联络表:$ name;
$ message =$ message;
$ headers ='From:myemail@my_domain.com'。 \\\\。
'回复:$ email'。 \\\\。
'X-Mailer:PHP /'。 phpversion();
mail($ to,$ subject,$ message,$ headers);
这个都很好,很漂亮,但仍然不能正常工作。
电子邮件 do 现在,但详细信息是:
from:myemail @ my_domain.com via servername.hosting_company.com
**回复:$email@servername.hosting_company.com**
to:myemail@my_domain.com
所以,回复地址仍然不是访客离开的。
帮我这个吗不知道还能做些什么。
非常感谢!

尝试更改这部分代码:
$ subject =Contact form:$ name;
$ message =$ message;
$ headers ='From:myemail@my_domain.com'。 \\\\。
'回复:$ email'。 \\\\。
'X-Mailer:PHP /'。 phpversion();
为此:
$ subject =Contact form:$ name;
$ message =$ message;
$ headers ='From:myemail@my_domain.com'。 \\\\。
'Reply-To:'。 $电子邮件。 \\\\。
'X-Mailer:PHP /'。 phpversion();
基本上从单引号内取出 $ email ,并追加到该字符串
I bought a simple website template with a php contact form. Everything works great with the one small exception of actually receiving the messages sent via the form. That is, the contact form would show a success message, but the message would never arrive.
After a long back and forth with my hosting service, I found out that in order to avoid spoofing they won't allow emails to be sent where the FROM address they don't host. That is, if a visitor to the site writes down his gmail/yahoo etc. in the form, I won't get it.
They suggested using the email address hosted with them as the FROM address, and having the visitor's input email as the REPLY-TO address. This seems reasonable.
So I dug around (e.g. here: PHP reply-to error - comes with admin email not sender of contact form and php Contact Form on website and reply-to email )
and the answers suggest something adding a headers component:
$headers = 'From: webmaster@example.com' . "\r\n" .
'Reply-To: webmaster@example.com' . "\r\n" .
'X-Mailer: PHP/' . phpversion();
and also add it to
mail($to, $subject, $message, $headers);
so that's what I did. $email is defined in this template as what the visitor's email, so what I did was:
$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);
This is all nice and dandy but it still doesn't work well. Emails do go through now, but the details are:
from: myemail@my_domain.com via servername.hosting_company.com
**reply-to: $email@servername.hosting_company.com**
to: myemail@my_domain.com
so, the reply to address is still not what the visitor left.
Can you help me with this? Don't know what else I can do.
Many thanks!

Try changing this part of your code :
$subject = "Contact Form: $name";
$message = "$message";
$headers = 'From: myemail@my_domain.com' . "\r\n" .
'Reply-To: $email' . "\r\n" .
'X-Mailer: PHP/' . phpversion();
To this :
$subject = "Contact Form: $name";
$message = "$message";
$headers = 'From: myemail@my_domain.com' . "\r\n" .
'Reply-To: ' . $email . "\r\n" .
'X-Mailer: PHP/' . phpversion();
Basically take out the $email from inside the single quote and append it to that string
