Thanks! > > Ryan Check and initialize your input variables: if (!isset($_GET['action'])) { $action = ''; } else { $action = $_GET['action']; } switch ($action) { case 'something': do_something(); break; case 'something_else': do_something_else(); break; default: echo "Unrecognized action given"; break; } If this is something you need to do for every page on your site, put the if() check into an auto-prepended file or something.
