## Facebook Apps Creation

To access Facebook API you need to create Facebook App and specify App ID & App Secret at the time of call Facebook API. Follow the step-by-step guide to creating and configure a Facebook App from the App Dashboard.

For add a platform click on Settings link from the left side menu panel » Click on the Add Platform button » Choose Website category » Enter site URL.
Once you completed the above steps, your apps settings page would something like the below.

## Installation

1. Clone the Repository. 
2. Import dbUsers.sql file through phpMyAdmin 
3. Open the User.php file and modify the $dbHost, $dbUsername, $dbPassword, $dbName variables value with your MySQL database credentials. 
4.Open the fbConfig.php file and specify the $appId, $appSecret, and $redirectURL as per your Facebook App credentials. 
5.Browse the index.php file in the browser and test the Login with Facebook functionality.

## Snippets

```<?php
session_start();

//Include Facebook SDK
require_once 'inc/facebook.php';

/*
 * Configuration and setup FB API
 */
$appId = '43........3187'; 								//Facebook App ID(create this from 																				developer.facebook.com)
$appSecret = 'ca55..............5add9a95f'; 			// Facebook App Secret
$redirectURL = 'http://fb.chasingpapers.com/'; // OAuth Uri  i.e. page where you want to redirect after 														                                                       login, this should be same as oauth login in dashboard

$fbPermissions = 'email';  //Required facebook permissions

//Call Facebook API
$facebook = new Facebook(array(
  'appId'  => $appId,
  'secret' => $appSecret
));
$fbUser = $facebook->getUser();
?>
```

## Tricks
In the Facebook App Dashboard: 1. Site Url / Mobile Site Url is the page where fb login button exists and 2. OAuth redirect URIs / Callback URI's is the page you want to get into after successful login(i.e. Website Home Login page => index.php) and this should be same as redirect url in fbconfig.php code
