I have figured out the drag and drop part but how would I then upload and POST the file to a URL with set parameters?
If I had a form I would just
<form enctype="multipart/form-data" method="post" action="url">
<input type="?" name="?"/>
<input type="?" name ="?" value="?"/>
</form>
How would I do above using the HTML5 drag and drop API???
