Hey,
Sorry for the late reply. Here are the instructions to do it. Let me know if you have any problems. You will have to signup at recaptcha's site and get your public and private keys. Also, upload the attached file to the nbs directory.
Open nbs/templates/default/new_forum.tpl
Find & Delete:
{if $S_captcha == 1}{literal}&& new_forum.captcha_code.value != ''{/literal}{/if}Find:
<a href="#" onclick="refresh_image();"><img style="border: 2px solid #000000" src="nbs/captcha.php?template={$S_template}" name="captcha" /></a><br /><br /><input type="text" name="captcha_code" size="31" onkeydown="enable();" onkeyup="enable();" tabindex="9" />Replace With:
{$captcha}Close & Save nbs/templates/default/new_forum.tpl
Open new_forum.php
Find:
define('PHRASE_TYPE', 4);Add Under (Make sure you put your public and private keys in the quotes below!!!):
define('RECAPTCHA_PUBLIC_KEY', 'PUT YOUR RECAPTCHA PUBLIC KEY HERE');
define('RECAPTCHA_PRIVATE_KEY', 'PUT YOUR RECAPTCHA PRIVATE KEY HERE');Find:
require_once('nbs/global.php');Add Under:
require_once('nbs/recaptchalib.php');Find & Delete:
OR ($nbs->setting['captcha'] AND empty($_POST['captcha_code']))Find:
// include captcha class
require('nbs/php-captcha.inc.php');
if (!PhpCaptcha::Validate($_POST['captcha_code']))
{
print_error_message($nbs->phrase['image_verification_code_incorrect_error']);
}
Replace With:
$resp = recaptcha_check_answer(RECAPTCHA_PRIVATE_KEY, $_SERVER["REMOTE_ADDR"], $_POST["recaptcha_challenge_field"], $_POST["recaptcha_response_field"]);
if (!$resp->is_valid)
{
print_error_message($nbs->phrase['image_verification_code_incorrect_error']);
}
Find:
if ($nbs->setting['captcha'])
{
$tpl->assign('L_image_verification', $nbs->phrase['image_verification']);
$tpl->assign('L_new', $nbs->phrase['new']);
}
Add Under:
$tpl->assign('captcha', recaptcha_get_html(RECAPTCHA_PUBLIC_KEY));Close & Save new_forum.php
