There is no built-in functionality. The details will depend on your requirements. Maybe point to some of the answers you have seen and explain what you don't understand.

I'm trying with dropzone.js but I have some difficult to integrate it in sqlform. Someone has used it with sqlform?
Thanks
Fabio

Perhaps this will help. This is not my code by the way. I modified it.

web2py.app.multi_upload2.w2p

Mind that with modern browsers (tested on chrome), dropzone is not necessary as it is the default behavior. All you need to do is use CSS to style the <input type="file"/> to make it clear to users they can drop files there.

Thanks Ron.
Thanks Massimo, I have 6 upload fields (img01, img02,...img06); there is way to use multiple upload with only one <input type="file" multiple> in a SQLFORM?

Thanks
Fabio

@fabio using dropzone.js helps, it can upload in parallel many files using the same SQLFORM, so it is not uploading in a single POST call, but many in parallel: one for each uploaded file.

The best way to do it is to write a specific action that handles just the file upload, independently from the rest of the form...

Parallel upload works correctly if you do not use a sqlite db since sqlite by design does not allow concurrent transactions
