Answer 1

You can't upload files with AJAX because you can't do multi-part encoded requests - that's a limitation of the XMLHttpRequest API.

Workarounds for this typically involve using an IFRAME that is the target of a form that handles the actual file upload as a separate sub-process to the overall form. The response loaded in the IFRAME then communicates back to the DOM in the parent/calling page with information about the uploaded file.

Answer 2

If you add a hidden iframe on the page

<iframe name="iframe1" ... />

And the change the target on your form to post to the iframe

<Form traget="iframe1" ...>...</form>

You can upload and post the data to the page. You can also use javascript (JQuery) to get hook into the events of the iframe.

To get a upload progress meter, use the php uploadprogress module. It works great! http://pecl.php.net/package/uploadprogress and http://bluga.net/projects/uploadProgressMeter/
