It returns no object because no record in the database satisfied the where condition. In other words, there is no data to turn into an object.

Perhaps the easiest solution is to have the callback respond in a logical way when its argument is null.

Oh... and for what it's worth. The following

PHP Code:
public function check_role($email){
   if ($email->user_role == 0) {
       return false;
   return true;

would be much more concise if written like this

PHP Code:
public function check_role($email){
   return $email->user_role != 0;

Or, if you want to account for the argument possibly being null

PHP Code:
public function check_role($email){
   return ! empty($email->user_role);
