how to integrate google reCAPTCHA in codeigniter?

I am working in codeigniter 2.4. I have to use google recaptcha in ony of my project.Below is my code.

// field validation
$this->form_validation->set_rules('recaptcha_challenge_field', 'Captcha Code', 'trim|required|xss_clean|callback_checkCaptcha');

The call back function is :

    function checkCaptcha($captcha){
    $resp = $this->recaptcha->recaptcha_check_answer ( $this->input->ip_address(), $this->input->post('recaptcha_challenge_field',true), $this->input->post('recaptcha_response_field',true));

    if($resp->is_valid)
    {
        return true;
        }

    else 
    {
         $this->form_validation->set_message('checkCaptcha', 'Sorry Invalid captcha code');
         return false;
        }

    }

But I am getting this error:

  A PHP Error was encountered

  Severity: Notice

  Message: Trying to get property of non-object

 Filename: controllers/offer.php

 Line Number: 59

Please help me where I am going wrong .

Thanks.

public function captcha_verify(){
    $form_response = $this->input->post('g-recaptcha-response');
    $url = "https://www.google.com/recaptcha/api/siteverify";

    $secretkey = "6LeBGG0UAAAAAEzWMaT0sOjPxcbNwQe7TiWWAknQ";

    $response = file_get_contents($url."?secret=".$secretkey."&response=".$form_response."&remoteip=".$_SERVER["REMOTE_ADDR"]);

    $data = json_decode($response);
    print_r($data);

    if (isset($data->success) && $data->success=="true") {
        echo "Successfully Passed through captcha";
    }
    else{
        echo "Please Fill captcha";
    }
}

I have updated my code and it works for me now. In the captcha library I have made the is_valid property public and then I replaced 

if($resp->is_valid)

with 

if($this->recaptcha->is_valid)

Now it works for me.

Thanks for all who responed my question.

You need to provide your private key in here too as the first parameter:

$resp = $this->recaptcha->recaptcha_check_answer ($private_key,  $this->input->ip_address(), $this->input->post('recaptcha_challenge_field',true), $this->input->post('recaptcha_response_field',true));
echo "<pre>";print_r($resp);die; #check the response array.
