I changed

$user = $this->facebook->require_login();

to

$this->user = $this->facebook->require_login();

in MY_Controller.php.

So I can use the log in user id value later on by using $this->user.

Yes, I revised my MY_Controller.php codes. I added below sentence also.

In traditional php programming, I just attach this at the end of facebookapi_php5_restlib.php, in the ci set up, the facebook client api is as plugin. 

So where and how should I save the code above?  Any suggestions?  Thanks.

by the way, why this thread is not moving to the top based on the last posted date?

You can add this array to application/config/facebook.php file as

And you shall call your array in everywhere like this:

Sorry if I post not related issues at this thread.  But I think you are the expert of CI facebook application here and this issue seems to modify on the codes of your controller or the other two controllers you mentioned.

I found some threads, using the same controller as yours, but add one line

parse_str($_SERVER[‘QUERY_STRING’],$_GET);

And then set up

$config[‘uri_protocol’]  = “PATH_INFO”;

or

$config[‘uri_protocol’]  = “ORIG_PATH_INFO”;

The reason to add this changes is to make the code like this working

<fb:iframe src=“http://cifacebook.foliosystems.ca/google_map” smartsize=true></fb:iframe>

the src is pointing to a CodeIgniter page, without the set up changes, facebook application doesn’t understand the url.

I did it, and it works.  But I am not quit clear about the codeigniter or facebook logic behind this set up.

Any advices?

does this still work i am getting

Fatal error: Class ‘Facebook_Controller’ r’ not found

Yes this class is still working. Your problem is MY_Controller.php problem, I guess.

Please check your application/config/config.php at 108th line at first.
It should be : $config[‘subclass_prefix’] = ‘MY_’;

Then check your location of MY_Controller.php file. It should be application/libraries
