Syntax of params block is wrong here. It probably should look like:

params =3D ( name =3D> John
           upload =3D> ( /home/john/file_name.txt ) )

or

params =3D ( name =3D> John
           upload =3D> ( /home/john/file_name.txt=20
                       file_name.txt ) )

or

params =3D ( name =3D> John
           upload =3D> ( /home/john/file_name.txt=20
                       file_name.txt
                       Content-Type =3D> text/plain ) )

Some background:

When you do file uploads content of form is encoded as multipart MIME
data streams (see RFC1867 for explanation) and each parameter is
represented as a separate MIME part which can have its own headers.

Syntax Explanation:

When you specify file upload parameter it is specified as a list which
looks like

    ( FILE, FILENAME, HEADER =3D> VALUE... )

where

FILE - is path to file which is sent to the server

(optional) FILENAME - filename which appear in the headers of
corresponding MIME part

(optional) HEADER =3D> VALUE, ... - These parameters let you to specify
additional headers for corresponding MIME part. For example they can
be used to specify a type of the uploaded file. I.e. text/plain for
plain text or image/png for PNG images.
