Joshua posted updates about the PHP AJAX File Upload Progress Meter. The patched version gives more information such as upload speed and estimated time to completion, Joshua also created wiki to start the documentation process. You can see the demo working online with patch and extension and without patch.
Over the weekend my file upload progress meter code got lots of traffic. It seems it made it made it on the del.icio.us popular list as well as getting over a thousands diggs. To celebrate this i’ve updated the code.

The basic way the code works is we take a form containing a file upload and submit it using a hidden iframe as a target. Doing this lets the upload happen in the background. Then we poll the server on a regular basis (say a 2 second interval) asking it for update status. If you have the patch+extension installed this gives you file upload speed etc. If you don’t have the extesion we stop making AJAX calls and just animate the status bar until the upload finishes in the iframe and tells us were done.
