You can pass additional variables to the upload script using either the POST or GET request
method. To send additional
POST variables to your upload script, you can use the following
code:
var fileRef:FileReference = new FileReference();
fileRef.addEventListener(Event.SELECT, selectHandler);
fileRef.addEventListener(Event.COMPLETE, completeHandler);
fileRef.browse();
function selectHandler(event:Event):void
{
var params:URLVariables = new URLVariables();
params.date = new Date();
params.ssid = "94103-1394-2345";
var request:URLRequest = new URLRequest("http://www.yourdomain.com/
FileReferenceUpload/fileupload.cfm");
request.method = URLRequestMethod.POST;
request.data = params;
fileRef.upload(request, "Custom1");
