can anyone help me to resolve the issue "An Error Was Encountered Non-existent class: recaptchalib"

Question

I am updating recaptcha library to recaptchalib.

I am getting this error.

An Error Was Encountered Non-existent class: recaptchalib

1. Include the library recaptchalib.php in library folder.
2. User controller:

    $this->load->library('recaptchalib');

    $data['fincaptcha_ok'] = $this->recaptchalib->recaptcha_get_html();

    $this->recaptchalib->recaptcha_check_answer($_SERVER['REMOTE_ADDR'],$this->input->post('recaptcha_challenge_field'),$this->input->post('recaptcha_response_field'));
    if(!$this->recaptchalib->getIsValid()) {
        $this->load->helper('directory');
        $data['error'] = 'incorrect captcha';
        $data['body_content']           = 'user/register';
        $this->load->view('template', $data);

3. View:<?php echo $fincaptcha_ok; ?>

Correct me if i'm wrong, but i think you use this recaptcha lib.

this Library provides a set of functions and has no object implementation. That said it should work if you use it like:

$this->load->library('recaptchalib');

$data['fincaptcha_ok'] = recaptcha_get_html();

$objResponse = recaptcha_check_answer($_SERVER['REMOTE_ADDR'],$this->input->post('recaptcha_challenge_field'),$this->input->post('recaptcha_response_field'));

if(!$objResponse->is_valid) 
{
    $this->load->helper('directory');
    $data['error'] = 'incorrect captcha';
    $data['body_content']           = 'user/register';
    $this->load->view('template', $data);
}

As an additional information, eventually it's better to use the built in captcha helper. Take a closer look at their documenation here.
