README

Install this package in your Rocker application and you will have a restful API that can authenticate users that has logged in using their facebook identities.

This installation walk through takes for granted that you have some prior knowledge about composer

1) Install PHP-Rocker

Here you can read more about how to get started with PHP-Rocker

2) Add the facebook login package

Add "rocker/facebook-login" : "1.*" to the application requirements in composer.json and run composer update in the console.

3) Edit config.php

In the file config.php you add your facebook application data and change the authentication class to Rocker\FacebookLogin\Authenticator. You will also have to add the facebook connect operation.

return array(
    ...

    'application.operations' => array(
        ...
        'facebook/connect' => '\\Rocker\\FacebookLogin\\Connect'
    ),

    'application.auth' => array(
        'class' => '\\Rocker\\FacebookLogin\\Authenticator',
        'mechanism' => 'facebook realm="your.website.com"'
    ),

    ...

    'facebook' => array(

        'id' => 'Facebook app id',
        'secret' => 'Facebook app secret',

        # (Optional) Comma separated string with data fields in the facebook response that
        # should saved as user meta when the user gets connected
        'connect_data' => 'birthday,locale',

        # (Optional) Comma separated string with authentication mechanisms that should be disabled
        'disabled_auth_mechanisms' => 'rc4,basic',
    )

);

4) Implementation

The following example uses rocker.js together with Facebook javascript SDK

<html>
<head></head>
<body>
    <button id="login-button">Login with FB</button>

    <script src="/scripts/rocker.js"></script>
    <script src="//connect.facebook.net/en_US/all.js"></script>

    <script>

    // Initiate FB
    FB.init({
        appId      : FB_APP_ID,
        status     : true,
        cookie     : false,
        oauth      : false
    });

    // Instantiate the Rocker server
    var rocker = new Rocker('https://api.mywebsite.com/');

    var onFacebookLogin = function() {

        // Connect user
        rocker.request({
            path : 'facebook/connect?access_token='+FB.getAccessToken(),
            method : 'POST',
            onComplete : function(status, json, http) {

                // set facebook auth data
                rocker.auth = 'facebook '+FB.getAuthResponse().userID+':'+FB.getAccessToken();

                // From here on you can access any operation that requires authentication
                rocker.me(function(rockerUser) {
                    console.log(rockerUser);
                });
            }
        });

    };

    // When user clicks on login button
    document.getElementById('login-button').onclick = function() {

        // Check login status
        FB.getLoginStatus(function(response) {
            if (response.status === 'connected') {
                onFacebookLogin();
            } else {

                // Login
                FB.login(function(response) {
                    if(response.status == 'connected') {
                        onFacebookLogin();
                    }
                }, {scope: 'email,user_birthday,user_location'});
            }
        });
    };

    </script>
</body>
