reCaptcha Integration
I just tried integrating reCaptcha to replace the original capcha anti-spam field. I got the original directions here:
http://wiki.recaptcha.net/index.php/...rate_reCAPTCHA
1. Download the reCaptcha.php here
http://recaptcha.net/plugins/php/ and place it in the classipress folder
2. Signup for reCaptcha here
http://recaptcha.net/api/getkey and take note of the private and public keys
3. In postform.php look for div class capcha and comment-out the code within this div.
4. Paste the following lines - take note to change the public and private keys to the ones reCaptcha gave after signing up:
<?php require_once('recaptchalib.php');
define('PUBLIC_KEY', '6LcTCgAAAAAAgOdATOWSL66jRLL6ioPibkgMp');
define('PRIVATE_KEY', '6LtYPgAAAAAAbodQWSLAP66jR997ioPibkgMp');
echo recaptcha_get_html( PUBLIC_KEY ); ?>
5. In form_process.php after "<?php" paste the following lines:
require_once('recaptchalib.php');
define('PUBLIC_KEY', '6LcTCgAAAAAAgOdATOWSL66jRLL6ioPibkgMp');
define('PRIVATE_KEY', '6LtYPgAAAAAAbodQWSLAP66jR997ioPibkgMp');
$response = recaptcha_check_answer(
PRIVATE_KEY, $_SERVER['REMOTE_ADDR'],
$_POST['recaptcha_challenge_field'],
$_POST['recaptcha_response_field']
);
6. Look for the if-statement that validates the spam field and comment it out
insert a new ifelse statement:
if ( $response->is_valid ) {}
else { $err .= __('The reCaptcha spam field is incorrect') . "
"; }
That's it! Let me know if this works or if you have suggestions in optimising the code
