Integrate Facebook Php Client

[eluser]mohrt[/eluser]
Yes, I just launched my first facebook app today.

http://apps.facebook.com/motortopia/

The only snafu I ran into was $_GET var clobbering by CI. I had to replace them in the controller. Here is a snippet:

Code:

class F8 extends Controller {
  function F8()
  {
    parent::Controller();
    // work around CI GET clobbering
    parse_str($_SERVER['QUERY_STRING'],$_GET);
    
    if($this->uri->segment(2) !== 'remove_app')
      require_once APPPATH.'/scripts/facebook_client/appinclude.php';
  }
  function index()
  {
     // you should use view files here, etc
     echo "Welcome!";
     // see all the $_POST data the Facebook environment gives you
     print_r($_POST);
  }
}

I dumped all the facebook client data in one directory then included the appinclude.php from the constructor.

My callback URL looks like http://www.mydomain.com/f8/

Anytime you call a URL like http://apps.facebook.com/myapp/foo/bar/blah, the callback URL fetched by Facebook will be http://www.mydomain.com/f8/foo/bar/blah

My post-remove URL is http://www.mydomain.com/f8/remove_app

The post-remove URL cannot include the appinclude.php file, thus the segment check.
