CakePHP 3 Facebook Plugin

A CakePHP 3.x Plugin to allow Facebook Login into an application.

Requirements

• CakePHP 3.x with Auth component correctly setup. Refer to http://book.cakephp.org/3.0/en/controllers/components/authentication.html for setup
• PHP 5.4.6+
• Facebook PHP SDK 4.0+
• Users Table with at least the following columns
  • facebook_id varchar(20)
  • first_name // can be set in config
  • last_name // can be set in config
  • username // can be set in config
  • password // can be set in config

For existing applications that already have a first_name, last_name, username and password already created with a different column name, you can dynamically set it in configuration options when loading the Component to your AppController.php file. See section 2 of Configuration below

NOTE: Facebook PHP SDK is a requirement. Composer will automatically install Facebook for you if not already installed. If manual download is chosen, you must download the Facebook Source into vendor/facebook/php-sdk-v4 and make sure it can be loaded by the composer. Else you need to manually include FAcebook's autoload.php file in your application's bootstrap.php.

Included

• Facebook Graph Component
• Facebook Graph Helper
  • $this->Facebook->loginLink()
  • $this->Facebook->loginButton()
  • $this->Facebook->likeButton()
  • $this->Facebook->shareButton()
  • $this->Facebook->sendButton()
  • $this->Facebook->followButton()
  • $this->Facebook->comments()
  • $this->Facebook->embeddedPosts()
  • $this->Facebook->embeddedVideo()
  • $this->Facebook->page()

***** See below for more details on how to use each

Installation

Composer (Best Choice)

1. Add the following to your composer.json located in the root of your application, in the require section . ie. /var/www/domain.com/composer.json

"require": {
	"akkaweb/cakephp-facebook": "dev-master"
}

2. Run the following at the root of your application

sudo php composer.phar update

Note: if composer.phar is not found, you need to install it. Follow CakePHP's documentation here -> http://book.cakephp.org/3.0/en/installation.html. Refer to Installing Cakephp section

Git Clone (plugins/AkkaFacebook)

git clone git@github.com:akkaweb/AKKA-CakePHP-Facebook-Plugin.git

Download

https://github.com/akkaweb/AKKA-CakePHP-Facebook-Plugin/archive/master.zip

Note: When installing with either manual download or Git Clone and CakePHP complains it cannot find the plugin, you need to add the plugin to vendor/cakephp-plugins.php in the plugins array [] --> 'AkkaFacebook' => $baseDir . '/plugins/AkkaFacebook/'. If you are using composer, running php composer.phar dumpautoload could be sufficient. If it does not work add the following to the "autoload" section in the root application's composer.json file in the "psr-4": section: "AkkaFacebook\\": "./plugins/AkkaFacebook/src"

Configuration

1. Load the plugin in your application's bootstrap.php file:

Plugin::load('AkkaFacebook', ['bootstrap' => false, 'routes' => true]);

2. Load the plugin's component in AppController.php

Note: You need to obtain your facebook App Id and App Secret from http://developers.facebook.com. Once you are on that page and have an App created, you can retrieve your App Id and App Secret. Make sure you add your domain to App Domains in the Settings page.

user_columns is optional and should only be used if your Users database columns defer from the defaults as specified in the Requirement section, above.

public function initialize(){
    parent::initialize();
    
    $this->loadComponent('AkkaFacebook.Graph', [
	    'app_id' => 'your-fb-app-id',
	    'app_secret' => 'your-fb-app-secret',
	    'app_scope' => 'email', // https://developers.facebook.com/docs/facebook-login/permissions/v2.3
	    'redirect_url' => '', //ie. Router::url(['controller' => 'Users', 'action' => 'login'], TRUE),
	    'post_login_redirect' => '' //ie. Router::url(['controller' => 'Users', 'action' => 'account'], TRUE)
	    // 'user_columns' => ['first_name' => 'fname', 'last_name' => 'lname', 'username' => 'uname', 'password' => 'pass'] //not required
    ]);
}

Usage

Note: FacebookHelper is automatically loaded by the Graph Component. If that is not desired, add 'enable_graph_helper' => false, to $this->loadComponent() above.
