Pre-Event Files

Maintainer:Not configured

Uploads one or more files and attaches them to a KIO Link pre-event, or to every pre-event whose folio is listed in folios.

Files are stored as uploads/event_files/<file name>: a file with the same name as an existing one overwrites its content for every pre-event that uses it.

Any multipart field name is accepted; every file in the request is uploaded.

Bug: the event ID is read from a path parameter that does not exist, so without folios the files are uploaded but not attached to anything (matchedCount: 0).

Public: no session token is required and nothing is checked besides the IDs.
