UW Oshkosh How-To's: PloneFormGen scripts to store uploaded files in a folder

These scripts are part of the Communication Studies Jobs site, that use

• a PloneFormGen form allows job applicants to upload between one and five files
  
• another PloneFormGen form that allows references to upload a letter of recommendation
  

All files are automatically stored in a folder for each applicant, based on the applicant's email address.  The scripts check first if they need to create the folder.

The screencast showing the jobs site is at https://www.youtube.com/watch?v=1kuHmr84CoY&feature=youtu.be

Script for Applicant's Form

# Available parameters:
#  fields  = HTTP request form fields as key value pairs
#  request = The current HTTP request.
#            Access fields by request.form["myfieldname"]
#  ploneformgen = PloneFormGen object
#
# Return value is not processed -- unless you
# return a dictionary with contents. That's regarded
# as an error and will stop processing of actions
# and return the user to the form. Error dictionaries
# should be of the form {'field_id':'Error message'}
