Предотвратить закрытие модального режима в случае ошибки и ввода останется

Это то, что я хочу. Когда я нажал кнопку «Сохранить», в случае ошибки мой модал не исчезнет. И мой вклад останется.

Мой модал исчезнет, ​​если регистрация прошла успешно

У меня есть здесь коды и использование Laravel.

Вот вид и контроллер
