Authenticating a FACEBOOK Application - PHP

Question

i need to authenticate before posting to my own wall, so here is my code

function get_app_token($appid, $appsecret)
{
$args = array(
\'grant_type\' => \'c         


        

Answer 1

Value of $token is access_token=<YOUR_ACCESS_TOKEN>

You cannot pass $token value directly to the access_token parameter.

$token = get_app_token($appid, $appsecret);
$access_token = split('=',$token);
$attachment = array(
                    'message' => '',
                    'access_token' => $access_token[1],
                    'name' => 'Attachment Name',
                    'caption' => 'Attachment Caption',
                    'link' => 'http://apps.facebook.com/xxxxxx/',
                    'description' => 'Description .....',
                    'picture' => 'http://www.google.com/logo.jpg',
                    'actions' => array(array('name' => 'Action Text', 
                              'link' => 'http://apps.facebook.com/xxxxxx/'))
              );

Hope this will helps in making that work... :)

Answer 2

you can get access_token from session array of facebook object directly.

$session = $facebook->getSession();
$session['access_token'];

of course you need to be authorized. if session is not set you must redirect to loginUrl

$facebook->getLoginUrl(array('req_perms' => 'email,read_stream,publish_stream'));
// this will return url for your authorization

and request permission you need.

A client_credentials access token doesn't give any access to /me (who would "me" be in this case? there's nothing that ties it to a user), let alone posting access. It is for use only with application-level Graph API calls, like to get an application's Insights data.
