Re: [flexcoders] file uploads
Hard to respond without seeing the code (a link or a paste of the text would be good). But I suspect the code presumes event handlers that are not implemented in the snippet you are using. fileRef needs at least one event handler to handle what the user does when he selects an item for upload, and lots of other stuff.
You need some code that looks like this: p_fileReference.addEventListener(Event.CANCEL, onCancel); p_fileReference.addEventListener(Event.COMPLETE, onComplete); p_fileReference.addEventListener(
IOErrorEvent.IO_ERROR, onIOError); p_fileReference.addEventListener(Event.OPEN, onOpen); p_fileReference.addEventListener(ProgressEvent.PROGRESS, onProgress);// p_fileReference.addEventListener(
SecurityErrorEvent.SECURITY_ERROR, securityErrorHandler); p_fileReference.addEventListener(Event.SELECT, onSelect);This code should be called when you instantiate the fileRefrence.the on parameters above are references to functions that handle events. Their declarations look something like this:
public function onSelect(p_event:Event) :void { public function onCancel(p_event:Event) :void { public function onOpen(p_event:Event) :void { public function onComplete (p_event:Event) :void {
public function onProgress (p_event:ProgressEvent):void{ public function onIOError(p_event:IOErrorEvent) :void {Hope this helps.RegardsHankOn 7/6/06,

I am using the code from the docs and Flex Builder is telling this 1120:
Access of undefined property fileRef. and that the selectHandler and
completeHandler are undefined properties as well. I am declaring the var
fileRef, so i dont get why its doing this... very frustrating... -- diabetic? http://www.diabetesforums.com

Re: [flexcoders] file uploads
Hi Clint,
I've just this very moment solved that one! :-) I couldn't get what
was going on either, but this is what I did:
For the sake of trying it out a created a new application to do it.
I left all the imports and var declarations where they were, but put
all the rest of the method calls and functions inside another function
and then called that function using the creationComplete application
tag attribute.
see below
?xml version="1.0" encoding="utf-8"?
mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
layout="absolute" creationComplete="initApplication()"
mx:Script
![CDATA[
import flash.net.FileFilter;
import flash.net.FileReference;
import flash.net.URLRequest;
public var imageTypes:FileFilter = new FileFilter("Images
(*.jpg, *jpeg, *.gif, *.png)","*.jpg; *jpeg; *.gif; *.png");
public var textTypes:FileFilter = new FileFilter("Text
Files (*.txt, *rtf)","*.txt; *.rtf");
public var allTypes:Array = new Array(imageTypes,
textTypes);
public var myFileRef:FileReference = new FileReference();
public function initApplication(): void
{
myFileRef.addEventListener(Event.SELECT, selectHandler);
myFileRef.addEventListener(Event.COMPLETE,
completeHandler);
myFileRef.browse(allTypes);
try {
var success:Boolean = myFileRef.browse();
} catch (error:Error) {
trace("unable to browse for files");
}
function selectHandler (even:Event):void
{
try {
var params:URLVariables = new URLVariables();
params.date = new Date();
var request:URLRequest = new
URLRequest("http://www.myplace.com/FlexImageUpload.php");
request.method = URLRequestMethod.POST;
request.data = "">
myFileRef.upload(request, "fileField");
} catch (error:Error) {
trace("Unable to upload file");
}
}
function completeHandler(event:Event):void
{
trace("Uploaded");
}
}
]]
