Newbie Needs Form Protection

[pab1953]

I have a form on a Go Daddy server that uses GD's gdform.php (see below). Does this provide any sort of spam protection? If not, what can I do to stop spam?

Thanks.

<?php
 $request_method = $_SERVER["REQUEST_METHOD"];
 if($request_method == "GET"){
  $query_vars = $_GET;
 } elseif ($request_method == "POST"){
  $query_vars = $_POST;
 }
 reset($query_vars);
 $t = date("U");

 $file = $_SERVER['DOCUMENT_ROOT'] . "/../data/gdform_" . $t;
 $fp = fopen($file,"w");
 while (list ($key, $val) = each ($query_vars)) {
  fputs($fp,"<GDFORM_VARIABLE NAME=$key START>\n");
  fputs($fp,"$val\n");
  fputs($fp,"<GDFORM_VARIABLE NAME=$key END>\n");
  if ($key == "redirect") { $landing_page = $val;}
 }
 fclose($fp);
 if ($landing_page != ""){
header("Location: http://".$_SERVER["HTTP_HOST"]."/$landing_page");
 } else {
header("Location: http://".$_SERVER["HTTP_HOST"]."/");
 }


?>

You can't modify gdform.php on their servers, can you? Write up your own. recently discussed [webmasterworld.com] - follow the link in my post there to help you get started. I've never had to use captcha to stop link spam.
