I'm working with Gravity Forms to allow unregistered users to upload various file types: A. Actually files like PPT, PDF, DOC, PNG B. Entering a URL of an existing Youtube video

The form we created become a draft waiting to be published. We're now looking for a way to be able to:

  • In case it's an actual file like PPT embed a file viewer (a-la slideshare), and automatically add a preview picture of the contents of the file.

  • In case it's a video, obtaining a frame from the video for a preview.

Any suggestion on how to do this? Thanks,

You will have to use the gform_pre_submission action hook which runs after you submit your form to parse the $_FILES array and achieve what you are trying. – Rutwick Gangurde Nov 12 '11 at 6:00
