Question

I want to make a file chooser that can allow me to choose
(Browse) where's the file that i want to upload. Anyone know how to
create a file chooser with flex builder 2 ? I'm very appreciate for
any answer.

Answer 1

Here is an example that will make a file browser to choose
either an image or mp3 file:
private var upload_ref:FileReference;
private function upload_media():void {
var media_filter:FileFilter;
var filter_array:Array = new Array();
media_filter = new FileFilter("Images (*.jpg, *.jpeg, *.gif,
*.png)", "*.jpg; *.jpeg; *.gif; *.png");
filter_array.push(media_filter);
media_filter = new FileFilter("Audio (*.mp3)", "*.mp3");
filter_array.push(media_filter);
upload_ref = new FileReference();
upload_ref.browse(filter_array);
upload_ref.addEventListener(Event.SELECT, file_selected);
private function file_selected(evt:Event):void {
if (upload_ref.name != null &&
upload_ref.name.search(" ") == -1 &&
upload_ref.name.search("'") == -1) {
var sendVars:URLVariables = new URLVariables();
sendVars.file_path = "/path_on_server_to_upload_to";
var request:URLRequest = new URLRequest();
request.url = "
http://yourserver.com/upload_php_script.php";
request.data = sendVars;
request.method = URLRequestMethod.POST;
upload_ref.addEventListener(Event.COMPLETE, completeUpload);
upload_ref.upload(request);
} else {
Alert.show("File name can only include letters, numbers or
underbars. No spaces.");
