Unable to receive form details run on PHP script to email

[angienithya]

Hi, I am unable to get the details of the form submission to my email address. Below is my PHP code. The webserver is running Microsoft IIS 6.0. I even tried running .php test scripts and it failed.

<?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'];
 
 
//Validate first
 
if(empty($name)||empty($visitor_email)) 
 
{
    echo "Name and email are mandatory!";
    exit;
}
 
if(IsInjected($visitor_email))
 
{
    echo "Bad email value!";
    exit;
}
 
$email_from = '[e-mail]';//<== update the email address
 
$email_subject = "New Form submission";
 
$email_body = "You have received a new message from the user: $name.\n".
 
"User's email: $visitor_email. \n".
 
"User's contact number: $phone. \n".
 
"Here is the message: $message";
 
 
$to = "[e-mail]";//<== update the email address
 
$headers = "From: $email_from \r\n";
 
$headers .= "Reply-To: $visitor_email \r\n";
 
//Send the email!
 
mail($to,$email_subject,$email_body,$headers);
 
//done. redirect to thank-you page.
 
header('Location: thank-you.html');
 
 
// 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;
  }
}
 
?>
