Facebook app development environment on localhost

I am running an app live at domain.com and wants to continue the development on localhost for which I setup local.domain.com to 127.0.0.1 in my hosts file. Everything works fine other than PHP is not able to pick up session when the login is handled by the JS SDK.

My JS code:

FB.login(func开发者_如何学运维tion(response) {
        if (response.session) {
            if (response.perms) {
                // user is logged in and granted some permissions.
                // perms is a comma separated list of granted permissions
                init();
            } else {
                // user is logged in, but did not grant any permissions, eh?
                showMessage( "Error!", "You haven't grant proper permissions!" );
            }
        } else {
            // user is not logged in
            showMessage( "Error!", "You are not logged in" );
        }
    }, {perms:'email'});

After the login from JS, I do an AJAX call where PHP can't pick up session information. My PHP code:

$session = $facebook->getSession(); // this is null somehow

The same code works fine, live on domain.com but on localhost, the $session on PHP side is null. Any ideas?

Did you try using localhost as your application domain name?

You should probably create 2 apps, one for your local testing and another one for your live code.
