сначала я прошу прощения за мой плохой английский, у меня проблема с моим кодом, когда я хочу запросить и проверить, находится ли пользователь, который входит в систему, в базе данных или нет, а также проверить его пароль, и если он турист или гид, и когда я отлаживаю программу, первое утверждениепередается и вторая проверка пароля, он никогда не проходил и не запускал следующую страницу, в ней говорится, что пароль неверный, как я решаю эту проблему, пожалуйста: (
