"Thank You" Redirect Page

Hi,
I want my form to redirect to a “thank you” page when someone contacts me. Yea, I took out my email I don’t like people seeing that :thumb:.

<?php
if(isset($_POST['email'])) {
    
    // EDIT THE 2 LINES BELOW AS REQUIRED
    $email_to = "Email Address";
    $email_subject = "Email Subject";
    
    
    function died($error) {
        // your error code can go here
        echo "We are very sorry, but there were error(s) found with the form your submitted. ";
        echo "These errors appear below.<br /><br />";
        echo $error."<br /><br />";
        echo "Please go back and fix these errors.<br /><br />";
        die();
    }
    
    // validation expected data exists
    if(!isset($_POST['first_name']) ||
        !isset($_POST['email']) ||
        !isset($_POST['comments'])) {
        died('We are sorry, but there appears to be a problem with the form your submitted.');        
    }
    
    $first_name = $_POST['first_name']; // required
    $email_from = $_POST['email']; // required
    $comments = $_POST['comments']; // required
    
    $error_message = "";
    $email_exp = "^[A-Z0-9._%-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$";
  if(!eregi($email_exp,$email_from)) {
      $error_message .= 'The Email Address you entered does not appear to be valid.<br />';
  }
    $string_exp = "^[a-z .'-]+$";
  if(!eregi($string_exp,$first_name)) {
      $error_message .= 'The Name you entered does not appear to be valid.<br />';
  
  }
  if(strlen($comments) < 2) {
      $error_message .= 'The Comments you entered do not appear to be valid.<br />';
  }
  
  
  }
  if(strlen($error_message) > 0) {
      died($error_message);
  }
    $email_message = "Form details below.

";
    
    function clean_string($string) {
      $bad = array("content-type","bcc:","to:","cc:","href");
      return str_replace($bad,"",$string);
    }
    
    $email_message .= "Name: ".clean_string($first_name)."
";
    $email_message .= "Email: ".clean_string($email_from)."
";
    $email_message .= "Comments: ".clean_string($comments)."
";
    
    
// create email headers
$headers = 'From: '.$email_from."
".
'Reply-To: '.$email_from."
" .
'X-Mailer: PHP/' . phpversion();
@mail($email_to, $email_subject, $email_message, $headers);  
?>

<!-- include your own success html here -->
