Question

This is a really frustrating problem (bug?) that I’ve been trying to figure out. Seems like alot of people complain about the same exact issue, but there’s no definite solution or tutorial fixing this issue.

Anyways, my problem is that I can get the SDK to log the user in just fine, however when they click on LogOut. It redirects them to facebook.com/home.php (even though the ‘next’ parameter is set to my site) and the User is still not logged out when I visit my site again…

Here is the code…(Facebook library is autoloaded thru the Codeigniter Configuration)

public function DestroySession()
{
        $this->load->helper('url');

if($this->facebook->getUser())
{
    $this->facebook->destroySession();


    $logout = $this->facebook->getLogoutUrl(array("next" => "http://mysite.com/"));


    redirect($logout, 'location', 301);
}
 }

So I got this to finally work. You can see the new function below. For some reasons that I am not entirely sure about you have to do these steps.

public function DestroySession()
{
    $this->load->helper('url');



//Get User ID
$user = $this->facebook->getUser();

if ($user)
{
    try
    {
        // Proceed knowing you have a logged in user who's authenticated.
       $user_profile = $this->facebook->api('/me');

   //   print_r($user_profile);
    } catch (FacebookApiException $e)
    {

        log_message('eror', $e);

        $user = null;
    }
}

// Login or logout url will be needed depending on current user state.
if ($user)
{
if( session_id() ){} else { session_start() ; }

    $logoutUrl = $this->facebook->getLogoutUrl($params = array('next' => base_url()));
    //echo 'Logout; '.($logoutUrl);
    $this->facebook->destroySession();
    redirect($logoutUrl, 'refresh');



}
}

See my orignal question for more context.

public function DestroySession()
{
    $this->load->helper('url');



//Get User ID
$user = $this->facebook->getUser();

if ($user)
{
    try
    {
        // Proceed knowing you have a logged in user who's authenticated.
       $user_profile = $this->facebook->api('/me');

   //   print_r($user_profile);
    } catch (FacebookApiException $e)
    {

        log_message('eror', $e);

        $user = null;
    }
}

// Login or logout url will be needed depending on current user state.
if ($user)
{
if( session_id() ){} else { session_start() ; }

    $logoutUrl = $this->facebook->getLogoutUrl($params = array('next' => base_url()));
    //echo 'Logout; '.($logoutUrl);
    $this->facebook->destroySession();
    redirect($logoutUrl, 'refresh');



}
}
