Я написал HTML-форму в bws.html чтобы пользователь мог вводить записи. После нажатия кнопки «отправить» форма будет направлена на form_action.php . Он отобразит пользовательский ввод и позволит пользователю проверить их ввод. После подтверждения и нажатия кнопки «Подтвердить и сохранить» вводимые пользователем данные будут сохранены в текстовом файле.

Однако, когда я нажал кнопку «подтвердить и сохранить», она перешла на новую веб-страницу и показала только те две кнопки, которые я сделал в form_action.php . Он не сгенерировал новый текстовый файл ‘data.txt «автоматически в корневом каталоге моего документа веб-сервера Apache.

Я новичок в html и php. Как я могу решить эту проблему?

Большое спасибо за вашу помощь.

Вот моя html-форма и php-код:

bws html:
