FileReference, return data from server side upload script

[springframework]

I have php upload code that uploads the file. this works!

now what i need is to return data from the server side upload script to the client.

i do 'echo' with php to print out whatever i want but then inside the completeHandler i get this error.

ReferenceError: Error #1069: Property data not found on flash.net.FileReference and there is no default value.
at ---------------::--------/completeHandler()

PHP Code:

file.addEventListener(DataEvent.UPLOAD_COMPLETE_DATA, completeHandler);
file.upload(uploadURL);

function completeHandler(event:Event):void {
    _output.text = "completeHandler: " + event.target.data;
} 


i have also tried

file.addEventListener(Event.COMPLETE, completeHandler);

Well from the server you have to use flash.net.URLLoader to get the data or you could use flash.display.Loader if the data is image or swf file

When you upload the file, the php should move the file somewhere where the file can be requested by flash.

var request:URLRequest = new URLRequest("yourfile.txt");
            loader = new URLLoader();
            try {
                loader.load(request);
            }
            loader.addEventListener(Event.COMPLETE,handleFileLoaded);

but this code should fire after file.addEventListener(Event.COMPLETE, completeHandler); the completeHandler fires , so that the file is uploaded for sure

and you should have the function

function handleFileLoaded(event:Event){
          trace(event.target.data);
}

[springframework]

ok i figured it out. this works now.

PHP Code:

file.addEventListener(DataEvent.UPLOAD_COMPLETE_DATA, completeHandler);
file.upload(uploadURL);

function completeHandler(event:Event):void {
    _output.text = "completeHandler: " + event.data;
} 


P.S. ignore what AleksandarAndreev was saying above, its useless to this problem

well, the reason you are getting the error is because you by typing event.target.data you are trying to access data property in the filereference, and you can't do this . The FileReference doesn't have data property , only the URLLoader has and you should use both FileReference and URLLoader in order to upload the file and than to load it in flash.

[AleksandarAndreev]

and of course you should start loading the uploaded file , after it complete its uploading, so you shouldn't use

file.addEventListener(DataEvent.UPLOAD_COMPLETE_DA TA, completeHandler);

you should use

file.addEventListener(Event.COMPLETE, completeHandler);

in order to check when the uploading has completed.

I don't think that it works just because the Event object doesn't have property data which you are trying to access by event.data

[springframework]

sorry this works!

PHP Code:

file.addEventListener(DataEvent.UPLOAD_COMPLETE_DATA, completeHandler);
file.upload(uploadURL);

function completeHandler(event:DataEvent):void {
    _output.text = "completeHandler: " + event.data;
}

Yep - agree this is the correct way.

Normally you'd use event.target.data if you were using URLLoader with the Event class as the event parameter.

When it comes to uploading, you do use event.data because the data property exists inside the event parameter which is a DataEvent class, a sub class of the Event class. The FileReference class doesn't have a data property, so the event.target.data should fail.

I am having the same problem. Upon upload I am trying to get some data back from php to flash. I need php to rename the image and return the new name to flash I cant make out from your snipets the whole process can you post a working sample of php and flash.

thanx much dave

Dave - which Browser are you testing this in?

In IE, the return of data would return painlessley. I've found Mozilla & Safari to not work. I had to write a custom class to get this to work on those 2 browsers.
