Where req.form comes into it is that it is the prevailing convention that if anything ever creates an instance of util.FieldStorage, that it store it as req.form. It should only create the instance of util.FieldStorage though if req.form doesn't already exist. Thus the code for a handler becomes: if not hasattr(req, 'form'): req.form = util.FieldStorage(req) upfile = req.form.getfirst('UploadFile') if upfile: ... This is what mod_python.publisher and mod_python.psp do in more recent versions. Peoples comments about req.form were referring to that under the belief that the person was using one of the handlers that leaves the form it creates as req.form. The person was however using a basic handler where it isn't created and so they would have to create it themselves. Following best practice, they should when they create the form, store it as req.form as the code I give shows. Using this convention you have a better chance of things working when integrating different handler mechanisms together as you will inherit the form created by another handler instead of creating it again and loosing your POST data. BTW, one is best off using getfirst() instead of either subscript operator or getlist(). By using getfirst() in preference to getlist(), you do not have to then access the first element as only one will be returned or None if it doesn't exist. If there is no field, getlist() returns an empty list and access the first entry in the list will raise an exception. It is also better than using subscript operator as it will raise an exception if field doesn't exist also and if it does exist can return either a single field object or a list of fields if there were duplicated entries.
