Launching a contact form thank-you page

Hello,

any kind chaps out there that can help with this?

instead of displaying the “Data has been submitted to…”
how might i alter the code to launch a thank you page
using “header” and if sending fails make it launch an
error page?

its the code provided in the php tutorial section. i
want to keep it simple cos im certainly no progammer!

thanks

<?php
if(isset($_POST['submit'])) {

    $to = "info@conflictingpixels.com"; 
    $subject = "MK Removals Website Contact Form";
    $name_field = $_POST['name'];
    $email_field = $_POST['email'];
    $message = $_POST['message'];
    $option = $_POST['radio'];
    $dropdown = $_POST['drop_down'];

    foreach($_POST['check'] as $value) {
        $check_msg .= "Checked: $value
";
    }
    
    $body = "From: $name_field
 E-Mail: $email_field
 $check_msg Option: $option
 Drop-Down: $dropdown
 Message:
 $message
";

    echo "Data has been submitted to $to!";
    mail($to, $subject, $body);
    
} else {
    echo "blarg!";
}
?>
