Facebook PHP SDK v4 Examples

My name is Sohaib Ilyas better known as Roomi and here in this repository I am going to upload all the PHP files related to latest Facebook PHP SDK v4 which will be related to the video series on codenmind.com website.

Usage

All you need to do is to download the whole ./src/Facebook from https://github.com/facebook/facebook-php-sdk-v4/tree/4.0-dev and then upload the downloaded Facebook folder to your hosting and then watch the video tutorials on http://codenmind.com/facebook-sdk-v4-php-tutorials/ to learn that how you can get your own Facebook Developer account and make it up and running after making Facebook Developer account and uploading the Facebook folder to your hosting all you need to do add different lines of code as you can see different examples here like getting basic info about user, posting on timeline etc etc just use different examples and make sure you have included all the classes the first in the start of the index.php file, and the example below is for the canvas app which works on Facebook with apps.facebook.com/APP_NAMESPACE/ link.

<?php
session_start();
require_once( 'Facebook/HttpClients/FacebookHttpable.php' );
require_once( 'Facebook/HttpClients/FacebookCurl.php' );

} catch (FacebookRequestException $ex) {
	echo $ex->getMessage();
} catch (\Exception $ex) {
	echo $ex->getMessage();
}

if ($session) {
	try {
		$request = new FacebookRequest($session, 'GET', '/me');
		$response = $request->execute();
		$me = $response->getGraphObject();
		echo $me->getProperty('name');
	} catch(FacebookRequestException $e) {
		echo $e->getMessage();
	}
} else {
	$helper = new FacebookRedirectLoginHelper('https://apps.facebook.com/APP_NAMESPACE/'); // add your Facebook app namespace here
	
	// getting the login url for your app
	$auth_url = $helper->getLoginUrl(array('email')); // add new permission here as an index type array
	
	// redirecting the user directly to your Facebook canvas app you can also make a link of it
	echo "<script>window.top.location.href='".$auth_url."'</script>";
}
