class TumblrLoginController extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->library('session');
}
Public function index()
{
$consumerKey = "YOUR_CONSUMER_KEY";
$consumerSecret = "CONSUMER_SECRET KEY";

$client = new Tumblr\API\Client($consumerKey, $consumerSecret);
$requestHandler = $client->getRequestHandler();
$requestHandler->setBaseUrl('https://www.tumblr.com/');

// If user visiting the first time
if (!$_GET['oauth_verifier']) {
// grab the oauth token
$resp = $requestHandler->request('POST', 'oauth/request_token', array());
$out = $result = $resp->body;
$data = array();
parse_str($out, $data);

$oauthData = array(
't' => $data['oauth_token'],
's' => $data['oauth_token_secret']
);

$this->session->set_userdata($oauthData);
echo '<a href="https://www.tumblr.com/oauth/authorize?oauth_token=' . $data['oauth_token'].'"> Login With Tumblr </a>';
} else {
$verifier = $_GET['oauth_verifier'];
// use the stored tokens
$client->setToken($this->session->userdata('t'), $this->session->userdata('s'));
// to grab the access tokens
$resp = $requestHandler->request('POST', 'oauth/access_token', array('oauth_verifier' => $verifier));
$out = $result = $resp->body;
$data = array();
parse_str($out, $data);
// and print out our new keys we got back
$token = $data['oauth_token'];
$secret = $data['oauth_token_secret'];
//echo "token: " . $token . "<br/>secret: " . $secret;

// and prove we're in the money
$client = new Tumblr\API\Client($consumerKey, $consumerSecret, $token, $secret);
$info = $client->getUserInfo();
echo "<br/><br/>congrats " . $info->user->name . "!";
}
}
}
