Question

Is there a Codeigniter library available that allows me to

• Login users with their Facebook account
• Import profile data, including interests?

This library by Elliot Haughin should cover the login part but I’m less sure about importing profile data.

Anyone have information about this?

Answer 1

The official Facebook PHP SDK actually works fine with Codeigniter.

put base_facebook.php and facebook.php in your libraries directory

create a facebook.php file in your config directory with these contents

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');

$config['appId']  = 'YOUR_APP_ID_HERE'; 
$config['secret'] = 'YOUR_APP_SECRET_HERE';

then use it like this

...
$this->load->library('facebook');

//Example usage from sdk example
if ($user) {
    try {
        // Proceed knowing you have a logged in user who's authenticated.
        $user_profile = $this->facebook->api('/me');
    } catch (FacebookApiException $e) {
        error_log($e);
        $user = null;
    }
}

// Login or logout url will be needed depending on current user state.
if ($user) {
    $logoutUrl = $this->facebook->getLogoutUrl();
} else {
    $loginUrl = $this->facebook->getLoginUrl();
}
