Facebook session not being created

I am using this code to post to the user's wall :

require 'fb/src/facebook.php';
$facebook = new Facebook(array(
   'appId' => 'xxx',
   'secret' => 'xxx',
));
$params = array(
    'canvas' => 1,
    'scope' => 'publish_stream,email,user_about_me,user_birthday,user_website',
    'redirect_uri' => 'urlhere',
);

$fb_session = $facebook->getUser();

// Session based API call.
if ($fb_session) 
{
    try 
    {
         $args = array(
                  'message' =>  $_GET['by'],
                  'link' => 'linkhere/',
                  'caption' => $_GET['test']
                 );
         $post_id = $facebook->api("/me/feed", "post", $args);
     } 
     catch (Exception $e) 
     {

         $fb_login_url = $facebook->getLoginUrl($params);
         echo $e->getMessage();
     }
} 
else 
{
     $fb_login_url = $facebook->getLoginUrl($params);
}

The code is working till the point uuer clicks on login part to post. After that the url contains a code = xxxzz and a state =yyy but the $fb_session is 0.

This works sometimes without any changes. Please help!

You should include the access token when you try to post to some User Facebook wall.

First get access token:

$fbToken = NULL;
$fbToken = $facebook->getAccessToken();

right after $fb_session = $facebook->getUser();

and then include it in the $args array:

 'access_token' => $fbToken

if session is NOT created or access token is not valid, you should redirect the user back to re-authorize your Facebook App.

So in ELSE, you should add 

   header("Location: $fb_login_url ");

after $fb_login_url = $facebook->getLoginUrl($params);

  • assuming that everything else is correct, but the access_token is not valid, you should also include header("Location: $fb_login_url "); before echo $e->getMessage();

in both cases you are using getloginurl

shouldn't it be 

if ($fb_session) {
try {
$args = array(
'message' =>  $_GET['by'],
'link' => 'linkhere/',
'caption' => $_GET['test']
);
$post_id = $facebook->api("/me/feed", "post", $args);
} catch (Exception $e) {
$fb_logout_url = $facebook->getLogoutUrl;
.
.
