reCaptcha problems

Hello all,

I have setup recaptcha on my form and am having a few problems.

My form layout is as follows -

Form.php - page containing form fields and reCaptcha - source code is below -

<?php

require_once('recaptchalib.php');

$publickey = "XXXXXXXXXXXXXXXXXXXXXXXXX"; // you got this from the signup page

echo recaptcha_get_html($publickey);

# the response from reCAPTCHA

$resp = null;

# the error code from reCAPTCHA, if any

$error = null;

# are we submitting the page?

if ($_POST["submit"]) {

$resp = recaptcha_check_answer ($privatekey,

$_SERVER["REMOTE_ADDR"],

$_POST["recaptcha_challenge_field"],

$_POST["recaptcha_response_field"]);

if ($resp->is_valid) {

echo "You got it!";

# in a real application, you should send an email, create an account, etc

} else {

# set the error code so that we can display it. You could also use

# die ("reCAPTCHA failed"), but using the error message is

# more user friendly

$error = $resp->error;

}

}

echo recaptcha_get_html($publickey, $error);

?>

----------------------------------------------------------------------------------------------------

Process.php - page containing mail intructions as well as redirect if recaptcha was a success.

<?php

require_once('recaptchalib.php');

$privatekey = "XXXXXXXXXXXXXXXXXXX";

$resp = recaptcha_check_answer ($privatekey,

$_SERVER["REMOTE_ADDR"],

$_POST["recaptcha_challenge_field"],

$_POST["recaptcha_response_field"]);

if(!$resp->is_valid) {

header("location:newsletter-success.php");

die();

}

else if($resp->is_valid) {

header("location:newsletter-error.php");

}

mail( "XXXXXXXXXXXXXX", "Newsletter Sign Up",

"\nEnquiry From: - $name

\nPostcode: - $postcode

\nTelephone Number: - $telno

\nEMAIL ADDRESS:- $email

\nFurther Detail:- $furtherdetails

\nPrefered Contact Time:- $contacttime

\nInterested in the following newsletter/s:- $newsletters",

"From: NewsLetterService@XXXXXXXXXXXXXX" );

?>

------------------------------------------------------------------------------------------

Success.php - reCapthcha and information sent ok!

Error.php - reCaptcha error page with back function to re-enter reCaptcha code.

The form sends, and directs to the process.php form page, just stays there, it doesn't then re-direct to the success or error page?

Please help,

Regards
