ReCAPTCHA library - ignited

[eluser]inverse.chi[/eluser]
I am getting exactly the same problem. Dragged the files into a fresh CI 2.0 installation and am not able to validate even when the correct text is entered.

Any luck?

[quote author="fran-quero" date="1298090051"]Hello. JayTee, thank you very much for your work. It´s great to come to CI for first time and find it filled with usefull libraries.

I´ve installed reCaptcha, but I can´t make it work. My problem is the last step. The captcha form loads well, it´s validated when is blank, but when it´s filled it never validates, even if the 2 words are correct I always have the Incorrect Security Image Response.

A very important detail that I am embarrased for, is that the demo works perfect
But I have compare every line, I have read all the post from this thread, I have spent about 3 hours, and as the great Homer Simpson said: 'It´s my first day'.

Please, give me a light. Here´s my code:

Controller

Code:

function create_user()
{
  $this->data['title'] = "Create User";

  //validate form input
  $this->form_validation->set_rules('first_name', 'First Name', 'required|xss_clean');
  //.... more validations ...
  $this->form_validation->set_rules('recaptcha_response_field','lang:recaptcha_field_name','required|callback_check_captcha');

  if ($this->form_validation->run() == true)
  {
     //.......
  } else {
    $this->data['recaptcha'] = $this->recaptcha->get_html();
    $this->load->view('auth/create_user', $this->data);
  }
}

function check_captcha($val) {
      if ($this->recaptcha->check_answer($this->input->ip_address(),$this->input->post('recaptcha_challenge_field'),$val)) {
        return TRUE;
      } else {
        $this->form_validation->set_message('check_captcha',$this->lang->line('recaptcha_incorrect_response'));
        return FALSE;
      }
}

Thanks in advance for your help.[/quote]
