Question

Regards,

I have a problem with Facebook SDK-PHP and Codeigniter.

I do not get the user’s session when I try to capture and obtain basic data for that user.

The error I get is: “An active access token must be used to query information about the current user.”

And when I apply the “getUser ()”, I get “0”.

NOTE: I download the php-sdk and put on my directory libraries the files base_facebook.php and facebook.php

In my application/config/config.php I put the key and app_secret of my facebook application.

Config.php :

$config['base_url'] = 'http://localhost/myapp_local';
$config['app_id'] = 'xxxxxxxxxxxxxx';
$config['secret'] = 'xxxxxxxxxxxxxxxxxxxxxxxx';
$config['app_name'] = 'http://apps.facebook.com/myapp_local/';

In my Controller Main.php i have the follow code:

class Main extends CI_Controller {

    public function __construct() {
        parent::__construct();
        $fb_config = array(
            'appId' => $this->config->item('app_id'),
            'secret' => $this->config->item('secret')
        );
        $this->load->library('facebook', $fb_config);

    private function _getInfoUserFB() {
        try {
            $fb_id = $this->facebook->getUser();
            if ($fb_id) {
                $fb_data = $this->facebook->api('/me');
                return $fb_data;
            }
        } catch (Exception $exc) {
            echo $exc;
        }
    }
       [....]
}

Now, in my variables $fb_id , where obtain the bool value, always i have “0”.
So, when i try to get the data of the current user facebook always i have a Exception with the message: “An active access token must be used to query information about the current user.”

$fb_data['id'] = NULL
$fb_data['first_name'] = NULL
$fb_data['last_name'] = NULL

What i doing wrong here? Any step or setting I miss?

NOTE 2: I don’t have some button Login with Facebook, my app connect directly to facebook via the configuration of my app on facebook. (Canvas URL, Secure Canvas URL, Canvas Page, Site URL)

Note 3: My application have some permission that need require, So I put the necessary permissions on Settings-Permissions BUT don’t show me the option of “Auth Referrals” to show Dialog confirm permissions.

I use CodeIgniter version 2.1.3 and PHP-SDK v 3.2.0

You have to go to Facebook Developer Site -> Apps -> Permission. And set the basic info permission for your app.

Then in your function getLoginUrl(array("scope" => "user_about_me))), you have to give the parameters.

Finally you have to save the access token $this->facebook->getAccessToken();

If you have problems you can ask me. I have setup my Codeigniter with nearly all Social Media Platforms 🙂
