Tevens is submit meestal geen goede manier van het controleren want als je in een input veld op enter druk wordt het formulier gesubmit zonder de waarde van de knop door te sturen.
als je in een <input> name=test hebt staan moet je bij if($_POST['test']) natuurlijk wel diezelfde naam gebruiken.. hier gebruik je in de je form hele andere namen dan in je verwerking
dus bv:
