Right and for a good reason. The second stage of the preview form renders all of the submitted form fields as hidden fields. To render a large file upload field like that would cause problems in the user's browser (that hidden field could potentially have a very very large base64 encoded string etc.) > > def preview_post(self, request): > "Validates the POST data.

You might want to consider just creating a copy of the form preview application for your custom use. Here's one way to handle file uploads. When the file is upload in the first stage, save it in a temporary location (the new Upload File handlers let you do this quite easily.) Incorporate the filename and filesize into your custom hash and render the filename in a hidden field (instead of the file's contents.) The rest should follow from that. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
