Hello everyone!
This code is originally is written by: vendiddy (Topic) but, it’s using old validation class.
This one is packed and it uses new version of validation class.

Important! You must have account on reCAPTCHA.NET to get public and private keys. Without keys, this addon won’t work!!

Pack is here, it contains ReadMe and code.

Hope you’ll like this one.
Please report bugs and etc here.
Thanks.

Edit:
You can also download this addon from Wiki .

Thanks

Np, when you guys test it out, please let me know

I did have a small issue with this.

Due to extanding the Form Validation I had to do add this->  before CI. ie.

Hope this helps.

Anyone know how to get two recaptchas on one page? It currently will only display the second recaptcha.

For those wondering, I had to use the ajax method: http://recaptcha.net/fastcgi/demo/ajax

Okay, now I’ve been informed that it’s throwing an error. When you submit the form the “To use reCAPTCHA you must get an API key from…” error pops up. Any ideas?

Hello!

I did have a small issue with this.

Due to extanding the Form Validation I had to do add this->  before CI. ie.

function recaptcha_matches()
    {
        $this->CI =& get_instance();
        $this->CI->config->load('recaptcha');
        $public_key = $this->CI->config->item('recaptcha_public_key');
        $private_key = $this->CI->config->item('recaptcha_private_key');
        $response_field = $this->CI->input->post('recaptcha_response_field');
        $challenge_field = $this->CI->input->post('recaptcha_challenge_field');
        $response = recaptcha_check_answer($private_key,
                                           $_SERVER['REMOTE_ADDR'],
                                           $challenge_field,
                                           $response_field);
        if ($response->is_valid)
        {
            return TRUE;
        }
        else
        {
            $this->CI->form_validation->recaptcha_error = $response->error;
            $this->CI->form_validation->set_message('recaptcha_matches', 'The %s is incorrect. Please try again.');
            return FALSE;
        }
    } 

Hope this helps.
