My updateHunter() in HunterController.php file should make an update of the registration method information and redirect to the listing page if everything is ok, if not, it should return to the update form which will be shown message(s) to correct the problem of a certain field(s).
When returning to the form page form_update.php to make the user correct the failed fields I come across the error: Update Undefined variable $user_hunter.
