I would like to rename the files uploaded to a webform according to some tokens or the value in some other field.
I did some research on this and was surprised to find no definite solution.
- https://www.drupal.org/node/326738 => A patch supplied for token support but the discussion ends without a final working patch
- https://www.drupal.org/node/364752 => Discussion on "Renaming file upload fields using other form fields". Discussion ends in "Won't Fix"
- Webform, creating customized directories for uploaded files => Approaches have been suggested here but no final solution given.
