How to make a progress bar for a file upload ?

[Forki]

I made a website with AJAX and PHP for uploading and managing files. Not only files but also a lot of metadata and permissions. I have one page with a private, shared and public workspace. A form to create/modify/move/delete a folder or file is just a new layer on top of the current contents of the webpage. When a user presses submit, data is send to server thru ajax, data is checked. If OK a return message is send with an OK and the form disappears, otherwise the fields with the errors are highlighted. For a file upload I use a hidden iframe where the server sends a generated javascript: when OK form disappears, otherwise fields with the errors are higlighted. It is not just a file upload, but users has to specify a lot of metadata for each file depending on the type.
For large files I need something for the users so that they can see that the upload is busy, but I would like to close the form so that the users can contunue working. For this I need the upload of the file and display of the progress bar take place in a a different window or in another frame/place.

I will probably will have to use a perl-script to accomplish this, but I want to keep it as basic as possible. Just a progressbar, or maybe bytes send versus total bytesize, ... But only one file needs to be uploaded at the time.

Any solutions ?

Thanx,
