Add this bundle to your src/ dir and the Facebook PHP SDK to your vendor/ dir:
$ git submodule add git://github.com/FriendsOfSymfony/FacebookBundle.git src/FOS/FacebookBundle $ git submodule add git://github.com/facebook/php-sdk.git vendor/facebook -
Add the FOS namespace to your autoloader:
// app/autoload.php $loader->registerNamespaces(array( 'FOS' => __DIR__.'/../src', // your other namespaces )); -
Add this bundle to your application's kernel:
// app/ApplicationKernel.php public function registerBundles() { return array( // ... new FOS\FacebookBundle\FOSFacebookBundle(), // ... ); } -
Configure the
facebookservice in your config:# application/config/config.yml fos_facebook: file: %kernel.root_dir%/../vendor/facebook/src/facebook.php alias: facebook app_id: 123456879 secret: s3cr3t cookie: true # application/config/config.xml <fos_facebook:api file="%kernel.root_dir%/../vendor/facebook/src/facebook.php" alias="facebook" app_id="123456879" secret="s3cr3t" cookie="true" />If you do not include a
filevalue in the config you will have to configure your application to autoload theFacebookclass. -
Add this configuration if you want to use the
security component:# application/config/config.yml security: factories: - "%kernel.root_dir%/../src/FOS/FacebookBundle/Resources/config/security_factories.xml" providers: fos_facebook: id: fos_facebook.auth firewalls: public: pattern: /.* fos_facebook: true anonymous: true only_facebook: # with facebook entry point (redirect to the facebook login url) pattern: /only_facebook/.* fos_facebook: true access_control: - { path: /.*, role: [ROLE_USER, IS_AUTHENTICATED_ANONYMOUSLY] } -
Optionally define a custom user provider class and use it as the provider or define path for login
# application/config/config.yml security: factories: - "%kernel.root_dir%/../src/FOS/FacebookBundle/Resources/config/security_factories.xml" providers: fos_facebook: id: fos_facebook.user_provider firewalls: public: pattern: /.* fos_facebook: login_path: /facebook check_path: /facebook-check default_target_path: /facebook provider: fos_facebook anonymous: true
A templating helper is included for loading the Facebook JavaScript SDK and
initializing it with parameters from your service container. To setup the
Facebook JavaScript environment, add the following to your layout just after
the opening body tag:
<body>
<!-- inside a php template -->
<?php echo $view['facebook']->initialize(array('xfbml' => true)) ?>
<!-- inside a twig template -->
{{ facebook_initialize({'xfbml': true}) }}
If you will be adding XFBML markup to your site you may also declare the
namespace, perhaps in the opening html tag:
<html xmlns:fb="http://www.facebook.com/2008/fbml">
Just add the following code in one of your templates:
<!-- inside a php template -->
<?php echo $view['facebook']->loginButton(array('autologoutlink' => true)) ?>
<!-- inside a twig template -->
{{ facebook_login_button({'autologoutlink': true}) }}
This requires adding a getFacebookId() and setFBData() method to the User model.
