php - PHP 回复错误 - 附带管理员电子邮件而不是联系表的发件人

Question

我有下面的 PHP 联系表格，其中包含验证码以确保正确。但是，当我从网站回复电子邮件时，它会随机发送一封电子邮件，我认为这是服务器管理员，但是，我希望它是发送表单的人的电子邮件。下面是代码，你能不能帮我？

<?php session_start();
if(isset($_POST['Submit'])) {   if( $_SESSION['chapcha_code'] == $_POST['chapcha_code'] && !empty($_SESSION['chapcha_code'] ) ) {
$youremail = 'info@domain.com';
$fromsubject = 'www.domain.co.uk';
$title = $_POST['title'];
$fname = $_POST['fname'];
$mail = $_POST['mail'];
$phone = $_POST['phone']; 
$subject = $_POST['subject']; 

$message = $_POST['message']; 
$to = $youremail; 
$mailsubject = 'Message from Website'.$fromsubject.' Contact Page';
$body = $fromsubject.'

The person that contacted you is:  '.$fname.'
 Phone Number: '.$phone.'
 E-mail: '.$mail.'
 Subject: '.$subject.'

 Message: 
 '.$message.'


|---------END MESSAGE----------|'; 
echo "Thank you for your message. I will contact you shortly if needed.<br/>
Go to <a href='/index.html'>Home Page</a>"; 
mail($to, $subject, $body);
    unset($_SESSION['chapcha_code']);
} else {

echo 'Sorry, you have provided an invalid security code';
}
} else { 
echo "You must write a message. </br> Please go to 
<a href='/contact.html'>Contact Page</a>"; 
}
?> 

有人告诉我将以下内容放入代码中，但我应该把它放在哪里？

$headers = "From: $mail\r\n"; 
$headers .= "Reply-To: $mail\r\n";   

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

非常感谢

请更换

mail($to, $subject, $body);

用你的代码

   $headers = "From: $mail\r\n"; 
   $headers .= "Reply-To: $mail\r\n";   

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