未知的发件人或电子邮件标题中的其他电子邮件地址

Question

我正在尝试设置一个新的联系表。 我能够正确接收电子邮件和消息，但回复显示为（未知发件人）或我的名称服务器上的用户名，例如：coggi132@rs14.websitehostserver.net。 我已经看了4个小时了，删除并添加了我在网上看到的不同网络内容。 如果我将电子邮件地址硬编码到mail（...“ $ visitor_email”）部分中，它将起作用。 谢谢

这是html：

<form id="form" action="../assets/form-to-email.php" method="post">
    <p><label class="required" for="namet">Name</label>(required)<br /><input name="name" id="name" type="text" required/>
<input type="text" style="display:none;" id="zip" name="zip" placeholder="Leave this field blank" autocomplete="off"></p>
    <p><label class="required" for="mailt">E-mail</label>(required)<br /><input name="email" id="email" type="text" required/></p>
    <p><label for="phone">Phone</label><br /><input name="phone" id="phone" type="text" required/></p>
    <p><label class="required" for="message">Message</label>(required)<br /><textarea name="message" id="message" required></textarea></p>
    <p><input class="btn_m" type="submit" name="submit" value="Submit Form" /></p>
</form>

这是PHP

<?php
/*
if(!isset($_POST['submit']))
{
//This page should not be accessed directly. Need to submit the form.
echo "error; you need to submit the form!";
}*/
$name = $_POST['name'];
$visitor_email = $_POST['email'];
$message = $_POST['message'];
$phone = $_POST['phone'];

$email_subject = "New Message From NovaWebDev.com Form";
$email_body = "You have received a new message from $name.\n
Phone Number: $phone \n
Here is the message: $message \n".

$to = "info@novawebdev.com";//<== Website's email address
$headers = "From: $visitor_email \r\n";
$headers .= "Reply-To: $visitor_email \r\n";
//Send the email!
mail($to,$email_subject,$email_body, $headers);
//done. redirect to success page.
header('Location: /index.php/shared/email_success');


// Function to validate against any email injection attempts
function IsInjected($str)
{
  $injections = array('(\n+)',
          '(\r+)',
          '(\t+)',
          '(%0A+)',
          '(%0D+)',
          '(%08+)',
          '(%09+)'
          );
  $inject = join('|', $injections);
  $inject = "/$inject/i";
  if(preg_match($inject,$str))
    {
    return true;
  }
  else
    {
    return false;
  }
}

?> 

Answer 1

用这个;

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

Answer 2

我想通了。 我的电子邮件输入名为“ mail”，而我的php为“ email”。 感谢您的帮助。
