# Zend Framework Facebook Library
* Author:  Erick Rojas ([email protected])

The purpose of the Zend Framework Facebook Library is to provide a simple (and standarized) way
in which you can use the Facebook PHP SDK classes  within the recommended ZF project folder
hierarchy.

It's based on the Official Facebook PHP SDK. It has been modified so that all classes follow ZF
naming guidelines and a Resource has been created so that you can easily set your params from
application.ini

# INSTALLATION

Simply, copy the Facebook folder to your ZF library folder and add the following lines to your
application/configs/application.ini file replacing APP_ID and APP_SECRET with your own.

autoloadernamespaces[] = "Facebook_"
pluginPaths.Facebook_Resource = APPLICATION_PATH "/../library/Facebook/Resource"
resources.facebook.appid = "APP_ID"
resources.facebook.secret = "APP_SECRET"

# REQUIREMENTS

- Zend Framework 1.11+
- PHP 5.2 or newer.

# USAGE

From any Controller or Model, you can get the Facebook_Facebook object by reading the registry
key 'Facebook', after doing so you can call any of the available methods from Facebook Docs.

# EXAMPLE

$facebook = Zend_Registry::get('Facebook');
$user = $facebook->getUser();
		
if ($user) {
	try {
		// Proceed knowing you have a logged in user who's authenticated.
		$user_profile = $facebook->api('/me');
	} catch (Facebook_Api_Exception $e) {
		$user = null;
	}
}
		
// Login or logout url will be needed depending on current user state.
if ($user) {
	$logoutUrl = $facebook->getLogoutUrl();
	$this->view->link = $logoutUrl;
	$this->view->user = $user_profile;
} else {
	$loginUrl = $facebook->getLoginUrl(array('scope' => 'email,publish_stream'));
	$this->view->link = $loginUrl;
}
