Я пытаюсь вставить несколько отмеченных / не отмеченных значений в базу данных с помощью кнопки отправки.после нажатия кнопки отправки сначала в базу данных будет вставлено одно или несколько отмеченных значений флажка, а затем отмеченные / непроверенные изображения появятся в отмеченных флажках (какое проверенное изображение представляет значение 1, а непроверенное изображение представляет значение 0.)
Проблема:
Я попробовал метод, описанный ниже, но смог вставить только одно значение флажка в базу данных, для результата флажок появился как число вместо изображения с флажком / без проверки и требовался дляобновите страницу для отображения отмеченных / не отмеченных изображений.
