Is it possible to create a multipart form that uploads the file using  
an AJAX remote call? I’m having a hard time figuring out the syntax  
if it is possible!

Thanks,  
Tom

Hi, I can tell you that is absolutely not possible to upload files  
with AJAX or Javascript of any kind. JS has always been prevented from  
accessing the client filesystem as a basic security feature. The only  
way is regular POST

It isn’t possible. You can upload to a hidden div, though. Here’s a  
plugin that helps with that:

Which is but one solution to the problem. I prefer SWFUpload (http://  
swfupload.mammon.se/), because it doesn’t involve polling the server  
for upload progress (the small flash movie monitors the upload  
stream) and it allows better file selection (filtering of files, max  
size, multiple selections in dialog, Â…). You can see an  
implementation at [http://demo.placid.be/albums/11;manage](http://demo.placid.be/albums/11;manage)
