I'm not sure how i would hook SHtml.fileUpload into this because
swfupload lets me configure an URL
that it will post to for each file uploaded, I don't even need a form
to do this (this is all flash/swf). I currently
have a LiftView subclass that handles it and is processing it like
this:
S.request match {
case Full(req) =>
req.uploadedFiles.foreach { file: FileParamHolder =>
println("Name: " + file.name)
println("File name: " + file.fileName)
resizeAndSave(file)
}
case _ =>
}
I guess the only thing I need to change is using a custom dispatch
instead of the view in order to return my own LiftResponse instead of
a NodeSeq
back to the client.
Cheers,
Alli
