[SOLVED] Access FB User Access Token from CB Connect was created by timomer

Hi,

I wish to access the FB Access Token that is created for the user when logging in with CB Connect. I can see its stored in $access_token in /components/com_comprofiler/plugin/user/plug_cbconnect/hybridauth/Providers/Facebook.php

Is this stored in any CB Table?

Many thanks,
tim

It's not stored anywhere except in the session. If you want access to it you need to call HybridAuth API.

fyi, for anyone else having this question you can access the current sessions token with the following function:

Function getaccesstoken (){
	//gets current session fb access token
	$config = 'hybridauth/config.php';
	require_once( "hybridauth/Hybrid/Auth.php" );
	$hybridauth = new Hybrid_Auth( $config ); 
 
	// call Hybrid_Auth::getSessionData() to get stored data
	$hybridauth_session_data = $hybridauth->getSessionData();
	$deserialized_array = unserialize($hybridauth_session_data);
	//var_dump($deserialized_array);
	$a = $deserialized_array['hauth_session.facebook.token.access_token'];
	$a = split('["]', $a);

	return $a[1]; 	
}

this may not be the best way, I hacked it together over the last few days. fyi you need to download a copy of hybridauth, the config file just needs some basic settings.

You don't need to hack anything together you can call it using CB Connect usage of HybridAuth API. Example as follows. HybridAuth is included with CB Connect so you don't need an external copy.

try {
	$hybrid		=	new cbconnectHybrid();
	$adapter	=	$hybrid->getAdapter( 'Facebook' );
	$token		=	$adapter->token( 'access_token' );
} catch ( Exception $e ) {}

The above should pull their access token if it's stored in the HybridAuth session. You can also directly access the adapter api using the following.

$token		=	$adapter->api->getAccessToken();

the above access the Facebook API library directly. I still have no idea why you need the token. You can make API calls using the above usage as well without ever needing to pass the token or make your own CURL calls as HybridAuth will handle that for you.

Hi Krileon,

Thanks for the reply, yes im sure there is a better way to do this.

Unfortunately your examples bring back an empty $token

The reason I need the token is for another script on my site that pulls in other user information via my FB app (status updates, pictures, etc)

You can also call getSessionData using the above APIs as well. I can't see how double including HybridAuth solves this. The session data and the cookies are still there and all the same. You're just loading the same PHP library twice. The only way this makes sense if your PHP script is external to Joomla, but even then you could just load the existing library in CB Connects folder.
