Kohana Facebook Class

This class will help you easily integrate Facebook php sdk into your kohana application. It is written for use with Facebook's JS API for actual login/logout.

This class only exists so that you can get Facebook user details for your users.

Javascript Setup

Here is some sample javascript to paste at the bottom of your html document you wish to use Facebook data on:

<script>
	window.fbAsyncInit = function() {
		FB.init({
			appId   : '{{app_id}}',
			session : {{encoded_session}}, // don't refetch the session when PHP already has it
			status  : true, // check login status
			cookie  : true, // enable cookies to allow the server to access the session
			xfbml   : true // parse XFBML
	});

	// whenever the user logs in, we tell our login service
	FB.Event.subscribe('auth.login', function() {
	  window.location = "{{base}}users/fb_login"
	});
  };

  (function() {
	var e = document.createElement('script');
	e.src = document.location.protocol + '//connect.facebook.net/en_US/all.js';
	e.async = true;
	document.getElementById('fb-root').appendChild(e);
  }());
</script>

You will need to pass {{app_id}}, and a json_encode()'d session variable to connect to Facebook. I use Mustache in this example, but you can use whatever you'd like.

The auth.login event will fire whenever someone logs into your site with a Facebook login button (<fb:login-button autologoutlink="true"></fb:login-button>) and will redirect to your Facebook specific login page.

Class Usage

1. Kohana_Facebook::instance()->logged_in() - Tells you if the user is authenticated with facebook
2. Kohana_Facebook::instance()->account() - Gives you the raw user object provided by facebook_
