is there proper codeigniter library to work with facebook php sdk - php

Question

I have searched Google for Libraries for Facebook, and have found this one: http://www.haughin.com/code/facebook/,
but it seems a bit outdated.
I wanted something for this one: https://github.com/facebook/php-sdk/
I have written my own wrapper for it meanwhile, but it seems like I'm having some issues with $_REQUEST['...']

Answer 1

You can use Official PHP Facebook SDK in Codeigniter easily. The only problem is Facebook SDK needs $_REGISTER and in Codeigniter you don't have it.(Because of the mod_rewrite)
Here's the little solution:
1- This is for the $_REGISTER problem. Use this before loading Facebook class:
parse_str( $_SERVER['QUERY_STRING'], $_REQUEST );
2- Facebook SDK has 2 files. Put them into one file and save it to your application/helper folder as facebook_helper.php. Then loading and using is such an ease like this:
$this->load->helper( 'facebook' );
$facebook = new Facebook( array( 'appId' => 'XXX', 'secret' => 'xxx' ) );
// ... The rest is not different. You can read Facebook SDK examples

So here's a trick I used to use facebook PHP sdk with my CodeIgniter app. From the SDK code, take Facebook.php and take out the FacebookApiException class, and put it in a new file called FacebookApiException.php. Now, I put facebook.php and FacebookApiException.php into the models folder, and used them as regular models.
Here is the code I used for authenticating users and providing access to an application via Facebook.
function facebook_login(){
# Creating the facebook object
$facebook = new Facebook(array(
'appId' => 'XXXXXXXXXXXXXXXXX',
'secret' => 'XXXXXXXXXXXXXXXXX',
'cookie' => true
));
# Let's see if we have an active session
$session = $facebook->getSession();
if(!empty($session)) {
# Active session, let's try getting the user info
try{
$uid = $facebook->getUser();
$param = array(
'method' => 'users.getinfo',
'uids' => $uid,
'fields' => 'uid, username, name, profile_url, pic_big',
'callback' => ''
);
$user = $facebook->api($param);
} catch (Exception $e){
$url = $facebook->getLoginUrl(array(
'req_perms' => 'user_about_me, email, status_update, publish_stream, user_photos',
'next' => site_url() . 'user/facebook_login',
'cancel' => site_url()
));
redirect($url);
}
if(!empty($user)){
# User info ok?
print_r($user);
// Add user oauth token and info to DB, and then redirect to some controller in your application.
redirect('/'); // redirect to homepage
} else {
# For testing purposes, if there was an error, let's kill the script
die("There was an error.");
}
} else {
# There's no active session, let's generate one
$url = $facebook->getLoginUrl(array(
'req_perms' => 'user_about_me,email,status_update,publish_stream,user_photos',
'next' => site_url() . 'user/facebook_login',
'cancel' => site_url()
));
redirect($url);
}
}
Hope this helps.

You can handle it in clear way by writing a small library by inheriting Facebook SDK class. Please follow my post on http://www.betterhelpworld.com/codeigniter/how-to-use-facebook-php-sdk-v-3-0-0-with-codeigniter to get it working.
