Ok... I've been
playing with the file upload stuff all morning, and am 80% of the way there.
Here's a quick sample of what my Browse button fires:
private function fileBrowse():void
{
var imagesFilter:FileFilter = new FileFilter("Images", "*.jpg;*.jpeg");
imageFileRef.addEventListener(Event.COMPLETE, onComplete);
imageFileRef.addEventListener(ProgressEvent.PROGRESS, progressHandler);
imageFileRef.addEventListener(Event.SELECT, onSelect);
imageName.text = "";
imageFileRef.browse([imagesFilter]);
}
var imagesFilter:FileFilter = new FileFilter("Images", "*.jpg;*.jpeg");
imageFileRef.addEventListener(Event.COMPLETE, onComplete);
imageFileRef.addEventListener(ProgressEvent.PROGRESS, progressHandler);
imageFileRef.addEventListener(Event.SELECT, onSelect);
imageName.text = "";
imageFileRef.browse([imagesFilter]);
}
private function fileUpload():void
{
uploadProgressPopup = uploadProgressBar(PopUpManager.createPopUp(this, flexComponents.uploadProgressBar, true));
uploadProgressPopup = uploadProgressBar(PopUpManager.createPopUp(this, flexComponents.uploadProgressBar, true));
var urlVars:URLVariables = new
URLVariables();
urlVars.userID = model.currentUser.userID;
urlVars.mouseID = model.editMouse.mouseID;
uploadTarget.data = ""> uploadTarget.method = URLRequestMethod.POST;
for (var i:int=0; i < imageFileRef.fileList.length; i++){
imageFileRef.fileList[i].upload(uploadTarget);
}
}
private function progressHandler(event:ProgressEvent):void {
var percentLoaded:Number = Number((event.bytesLoaded / event.bytesTotal) * 100);
uploadProgressPopup.doUpdateProgress(percentLoaded);
Alert.show("The file is " + percentLoaded.toString() + "% loaded.");
}
private function onComplete(event:Event):void {
Alert.show("Done.");
PopUpManager.removePopUp(uploadProgressPopup);
}
urlVars.userID = model.currentUser.userID;
urlVars.mouseID = model.editMouse.mouseID;
uploadTarget.data = ""> uploadTarget.method = URLRequestMethod.POST;
for (var i:int=0; i < imageFileRef.fileList.length; i++){
imageFileRef.fileList[i].upload(uploadTarget);
}
}
private function progressHandler(event:ProgressEvent):void {
var percentLoaded:Number = Number((event.bytesLoaded / event.bytesTotal) * 100);
uploadProgressPopup.doUpdateProgress(percentLoaded);
Alert.show("The file is " + percentLoaded.toString() + "% loaded.");
}
private function onComplete(event:Event):void {
Alert.show("Done.");
PopUpManager.removePopUp(uploadProgressPopup);
}
Now, I can browse
just fine, and my upload button fires off the upload, and the files make it
safely to the server, where ColdFusion saves them to the filesystem. The only
problem is that my progressHandler() and onComplete() methods never
fire.
Is there some trick?
Do I need to have ColdFusion return something?
