Checking some form data constraints before uploading.

[radwasherif]

I basically want to validate some form data (e.g. certain fields are not empty, some input is in certain format.. etc.) before actually uploading the files.

What happens is that if I place a callback before the upload, req.body is empty.

Anyone solutions/workarounds for this?

From the documentation:

Note that req.body might not have been fully populated yet. It depends on the order that the client transmits fields and files to the server.

I wish I had an easy solution for you but the only thing I can recommend is to manually reorder the fields with javascript to make sure that fields are sent before files.

This has come up a number of times before, e.g. #322 and #146 where an workaround is outlined...
