Since Contao does not have a built-in support for "multiple file uploads", our
terminal42/contao-fineuploader
has added a handler in Contao 5 to convert an array of uploads to separate upload fields. So if you have an input fieldattachements
with fineuploader, you would get anattachements_0
,attachements_1
etc. property in$files
of Contao'sprocessFormData
hook.This PR normalizes this back to the expected format of normalized files (
attachements => [0 => ..., 1 => ...]
).
