What result is tossed by WPDB when there is no results to a query? Is it an empty result or a NULL return? IE What do I test for in a if statement? "" or NULL?
$userdata = $wpdb->get_row("SELECT * FROM $users_table WHERE user_email = $email", ARRAY_A);
I need to be able to know which result is thrown if no row is found that matches the query...
