How to upload files using jQuery's ajax function with PHP?

Question

Here\'s my nonworking attempt:

Answer 1

Actually, HTML5 and the new File API does support uploading via XmlHttpRequest. It works beautifully in Firefox 4 and Chrome.

Answer 2

XmlHttpRequest has no support to upload files. you need to use some hidden iframe or a flash solution.

Answer 3

You can not upload file using plain JS/AJAX. A known trick is to post your file to a hidden iframe and update the iframe.
