SPAM Contact Form How do I stop it?

[RobScotland]

Hi Folks Could someone please help me sort this little problem out. I have a contact form on my site and a few weeks ago I started to get SPAM. I have no idea how to stop this and if I can stop it. My have little knowledge of PHP. This is the script I have. I have had a look through the forum but if Im honest its goes right over my head. Thanks in advance.

 

<?php
    $email = "info@themcdonaldguesthouse.co.uk";
    $subject = "Contact Form";
    $message = "\name: ".$_POST['name'];
    $message .= "\nEmail Adress: ".$_POST['email'];
    $message .= "\nTelephone: ".$_POST['telephone'];
$message .= "\nday: ".$_POST['day'];
$message .= "\nmonth: ".$_POST['month'];
$message .= "\nyear: ".$_POST['year'];
$message .= "\nnights: ".$_POST['nights'];
$message .= "\nrooms: ".$_POST['rooms'];
$message .= "\npersons: ".$_POST['persons'];
$message .= "\nmessage: ".$_POST['message'];




    $message = addslashes($message);
    mail($email, $subject, $message);
    
header( "Location: http://www.themcdonaldguesthouse.co.uk/thankyou.html" );
?>

Google for captcha. Thats about the only way to stop spam bots.
