Below are instructions on how to add ReCaptcha to the Your_Account Module In PHP-Nuke 8.0
Files you will need:
recaptchalib.php (from http://recaptcha.net/plugins/php/)
config.php (from PHP-Nuke)
index.php (from modules/Your_Account)
recaptcha_functions.php (a file I give you)
First Get Your Public and Private Keys from ReCaptcha.net, and put them in the recaptcha_functions.php file
File:recaptcha_functions.php
<?php
/**
* $Id: $
* Author: Bandit-X <www.Bandit-X.Net>
* Licence: GNU
*/
if (!defined('MODULE_FILE')) {
die ("You can't access this file directly...");
}
require_once('recaptchalib.php');
$publickey = "my public key"; // you got this from the signup page
$privatekey = "my private key";
function recaptcha_showform()
{
global $publickey;
echo "<script type=\"text/javascript\">var RecaptchaOptions = { theme : 'white'};</script>";
echo recaptcha_get_html($publickey);
}
function recaptcha_showtable()
{
global $publickey;
echo "<tr><td colspan='2'><script type=\"text/javascript\">var RecaptchaOptions = { theme : 'white'};</script>";
echo recaptcha_get_html($publickey);
echo "</td></tr>";
}
function recaptcha_check(){
global $privatekey;
$resp = recaptcha_check_answer ($privatekey,
$_SERVER["REMOTE_ADDR"],
$_POST["recaptcha_challenge_field"],
$_POST["recaptcha_response_field"]);
return $resp;
}
function recaptcha_error()
{
include_once("header.php");
OpenTable();
echo "<center><font class=\"title\"><b>ReCaptcha Error!</b></font><br><br>";
echo "<font class=\"content\">The reCAPTCHA wasn't entered correctly. Go back and try it again<br>"._GOBACK."</font></center>";
CloseTable();
include_once("footer.php");
}
?>
Now lets Open up the index.php file from the Your_Account module, first make a backup of that file.

if(is_user($user)) {
include("modules/$module_name/navbar.php");
}

require_once('recaptcha_functions.php');
}
}
