Я использую fullcalendar , чтобы создать событие синхронизации в базе данных. Появляется модальное окно с возможностью удаления таблицы из базы данных. В этом же модальном окне я использую Cut File Browser php , чтобы перечислить все файлы в каталоге.
Моя цель - добавить для каждого файла возможность добавлять илиудалите его из базы данных, связанной с тем же созданным событием календаря.
Так что мне нужно добавить таблицу в базу данных, и для каждого файла мне нужны две кнопки. Один для добавления информации о file_path для каждого файла в базе данных, а другой для его удаления.
В то же время я хочу показать, какие файлы фактически добавляются в базу данных событий таблицы.

СУЩЕСТВУЮЩАЯ БАЗА ДАННЫХ:

Существующая база данных предназначена для полного календаря, мне нужнодобавить строку внутри таблицы для каждого файла path_file
