Question

My app allows users to send requests using Facebook Requests Dialogue.

I run the init as follow:

<div id="fb-root"></div>
<script src="http://connect.facebook.net/en_US/all.js"></script>
<script>
FB.init({
    appId: '193078857407882',
    status: true,
    cookie: true,
     xfbml: false,
       });
</script>

From what I understand in the documentation the ‘status: true’ is supposed to check if the user is logged in to facebook.

However in my app when the user is not logged in it just shows the following error message:

An error occurred with hbg. Please try again later.

How can I force the application to check if the user is logged in and if not to log in?

You can check login status by calling FB.getLoginStatus

    FB.getLoginStatus(function(response) {
        if (response.authResponse) {
        // logged in and connected user
        } else {
            FB.login(function(res) {
                if (res.authResponse) {
                    // user logged in
                } else {
                    // user cancelled login
                }
            });
        }
    });
