retaining upload file information in form when validation fails on other fields If there are required fields in a form (ie '#required' is set to TRUE), and the user sets a file to be uploaded but not provide all the required fields, validation fails on the required fields and the validation hook does not get called; the specified file does not get uploaded (if that is where the upload code is placed) and the form is refreshed without the previously provided filename wiped out. Is there a way to either upload the file during validation, or reset the filename in the form field, so that the user doesn't have to reselect it again? 

thanks
I believe using the File_Managed fieldtype will fix your problem. This Drupal FAPI field type uploads the file to a temp directory BEFORE the form is submitted, and so you can access the file during/after validation. You can see an example of it being applied in the "image_example.pages.inc" in the Examples module. Hope this helps.
