Adding ReCaptcha to the Registration Form

(EDIT: This is for Joomla 1.5)

I couldn't find precise instructions for Joomla 1.5 anywhere, but the following works for me:

Files to edit:

components/com_user/views/register/tmpl/default.php
components/com_user/controller.php

File to add (from the ReCaptcha website):
components/com_user/views/register/tmpl/recaptchalib.php

Replace the text YOUR-RECAPTCHA-PUBLIC-KEY and YOUR-RECAPTCHA-PRIVATE-KEY in the code below with the actual keys you received from the ReCaptcha website.

At the beginning of default.php ADD:

<script type= "text/javascript">
var RecaptchaOptions = {
theme: 'clean'
};
</script>

Look for the following line in default.php:

<button class="button validate" type="submit"><?php echo JText::_('Register'); ?></button>

BEFORE the line above ADD:

<?php
require_once('recaptchalib.php');
$publickey = "YOUR-RECAPTCHA-PUBLIC-KEY"; // you got this from the signup page
echo recaptcha_get_html($publickey);
?>

Look for the following line in controller.php:

global $mainframe;

AFTER this line ADD:

		require_once('views/register/tmpl/recaptchalib.php');
		$privatekey = "YOUR-RECAPTCHA-PRIVATE-KEY";
		$resp = recaptcha_check_answer ($privatekey,
		$_SERVER["REMOTE_ADDR"],
		$_POST["recaptcha_challenge_field"],
		$_POST["recaptcha_response_field"]);
		if (!$resp->is_valid) {
		die ("The reCAPTCHA wasn't entered correctly. Go back and try it again." .
		"(reCAPTCHA said: " . $resp->error . ")");
		}

That's it!

That means that you don't need to go and get new keys for every site you want to protect using recaptcha. Thanks for writing this up Nic.
