Codecs.mpFormDataDecode for each file found in the data, just before
the file is created and written. If null is returned then the file is
not created or written. This allows you to control which files are
written and the names of the resulting files.
For Codecs.mpFormDataEncode this is also invoked on each filename, allowing
you to control the actual name used in the filename attribute
of the Content-Disposition header. This does not change the name of the
file actually read. If null is returned then the file is ignored.
filename - the original filename in the Content-Disposition headerfieldname - the name of the this field, i.e. the value of the
name attribute in Content-Disposition
header
