    $recaptcha_google = trim($this->input->post('g-recaptcha-response'));
    $userIp_google= $this->input->ip_address();
    // put your google secret key hear
    $google_secret='put-your-secret-key-hear';
    $data_google_captcha = array(

        'response' => "$recaptcha_google",
        'remoteip' =>"$userIp_google"
    );
 
    $live_captcha_verfy = curl_init();
    curl_setopt($live_captcha_verfy, CURLOPT_URL, "https://www.google.com/recaptcha/api/siteverify");
    curl_setopt($live_captcha_verfy, CURLOPT_POST, true);
    curl_setopt($live_captcha_verfy, CURLOPT_POSTFIELDS, http_build_query($data_google_captcha));
    curl_setopt($live_captcha_verfy, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($live_captcha_verfy, CURLOPT_RETURNTRANSFER, true);
    $captcha_response = curl_exec($live_captcha_verfy);
    $status_capcha= json_decode($captcha_response, true);
    if(empty($status_capcha['success'])){
        return FALSE;
    }else{
        return TRUE;
    }
}

And Then create this simple ci validation rule as well as validation message

$this->form_validation->set_rules('g-recaptcha-response', 'recaptcha validation', 'required|callback_validate_captcha');
$this->form_validation->set_message('captcha_validation_google', 'Again Please check your Google the the captcha form');
