Facebook Extension for the Yii Web Framework

Authenticate a Facebook user within a Yii Web Application and consequently use the Facebook API. This extension is based on PHP-SDK.

Developed by @ielshareef.

Installation

Clone the repo onto your machine Copy it to the protected/extensions folder in your Yii Web Application root Rename the folder to "facebook" Update the config file:

'import'=>array(
	'application.models.*',
	'application.components.*',
	'ext.facebook.*',
	'ext.facebook.lib.*',
)

Add an action to your Controller (default is SiteController.php under protected/controllers)

// Facebook log in
public function actionFacebooklogin() {
	Yii::import('ext.facebook.*');
    $ui = new FacebookUserIdentity(YOUR APP ID, YOUR APP SECRET);
	if ($ui->authenticate()) {
        $user=Yii::app()->user;
        $user->login($ui);
    	$this->redirect($user->returnUrl);
 	} else {
    	throw new CHttpException(401, $ui->error);
	}
}

The default actionLogout() can handle all types of authentication logouts, so you don't need a new one

In your layout's main.php file, edit the menu to all the Facebook login:

<?php $this->widget('zii.widgets.CMenu',array(
	'items'=>array(
		....
		array('label'=>'Sign in with Twitter', 'url'=>array('/site/twitterlogin'), 'visible'=>Yii::app()->user->isGuest),
		array('label'=>'Sign in with Facebook', 'url'=>array('/site/facebooklogin'), 'visible'=>Yii::app()->user->isGuest),
		array('label'=>'Login', 'url'=>array('/site/login'), 'visible'=>Yii::app()->user->isGuest),
		array('label'=>'Logout ('.Yii::app()->user->name.')', 'url'=>array('/site/logout'), 'visible'=>!Yii::app()->user->isGuest)
	),
)); ?>

You are all good to go!

Authenticated User Data

Once the user is authenticated, his/her information will be stored in Yii::app()->session['facebook_user'].
