Facebook Integration Problem

[eluser]jdav3579[/eluser]
Hi,
After scouring numerous posts on this subject, I cant seem to get my Facebook application to connect.
In my htaccess:

Code:

#Force PHP5
#remove comments below for live site
#also in config change this $config['index_page'] = "index.php?"; to this $config['index_page'] = "";
AddType x-mapp-php5 .php

RewriteEngine on
RewriteCond $1 !^(index\.php|images|styles|scripts|favicon\.ico|favicon\.png|robots\.txt|sitemap\.xml)
RewriteRule ^(.*)$ index.php?/$1 [L]

My config:

Code:

$config['uri_protocol']    = "AUTO";
$config['enable_query_strings'] = TRUE;

In my application:

Code:

class fb extends MY_Controller {

    private $facebook;

    function fb(){
        parent::MY_controller();
        $this->load->helper('facebook/facebook');
        $this->facebook = new Facebook(array(
                  'appId' => 'xxxxx',
                  'secret' => 'xxxxx'
                ));
    }

    function index(){
        $session = $this->facebook->getSession();
      
    }

}

It would appear that no session is being set. Can anyone possibly point me in the right direction at all please?

How are you referring to your class since you have enabled querystrings? The manual gives the following example with querystrings enabled (with your controller and method substituted

index.php?c=fb&m=index&id=345

How do you know your session is not being set? What kind of feedback/error are you getting?

Hi, Thanks for the reply. I was trying various configuration options, with and without query strings enabled.I will try it without query strings enabled - but I think facebook was adding data onto the end of the query string which was confusing CI.

I tested to see if the session was being set by var_dumping 'session' after this line:

Code:

$session = $this->facebook->getSession();

So what was it returning?

Hi,
It was just returning (NULL).
Cheers

Here's some code from a facebook app I've been playing with using CodeIgniter. It hides index.php but I'm using a hack to get GET data also. enable querystrings is OFF.

Code:

class Myapp extends Controller {

    function __construct() {
        parent::Controller();
        //get GET vars
        parse_str(substr(strrchr($_SERVER['REQUEST_URI'], "?"), 1), $_GET);
    }

    function index() {

        $data = array();

        $this->load->config('myapp');
        $this->load->library('facebook', $this->config->item('fb_settings'));

        $data['session'] = $this->facebook->getSession();

        $data['me'] = null;
        if ($data['session']) {
            try {
                $data['uid'] = $this->facebook->getUser();
                $data['me'] = $this->facebook->api('/me');
            } catch (FacebookApiException $e) {
                error_log($e);
            }
        }

        // login or logout url will be needed depending on current user state.
        if ($data['me']) {
            $data['logout_url'] = $this->facebook->getLogoutUrl();
        } else {
            $data['login_url'] = $this->facebook->getLoginUrl();
        }

        // This call will always work since we are fetching public data.
        $data['bretticus'] = $this->facebook->api('/bretticus');

        $data['app_id'] = $this->facebook->getAppId();
        
        $this->load->view('myapp/canvas', $data);
    }
}

Hi Bretticus,
Thanks for your help! much appreciated. I have been kind of successful, I think I am going to have to do quite a bit of learning on the subject as I think I am not fully understanding the facebook side of things! I think I am going to have to buy a book, but thanks anyway!
