PHP Notices and Session Warning

(Update: edited code format slightly)

Plugin works great but when I was doing some debugging for another issue, I noticed that there were php notices stemming from line 46 in camera_functions.php. I just did a check for $current_user and that fixed the issue. Here’s the code:

if ($current_user) {
  if ($current_user->display_name == 'pixtest') {
    if(isset($_SESSION[$name])){
      if($_SESSION[$name]=='') {
        return $return;
      } else {
        return $_SESSION[$name];
      }
    } else {
      return $return;
    }
  } else {
    return $return;
  }
}
else {
  return $return;
}
