This series of classes easily manage the uploading, downloading, encoding and saving of files into and out of Flash to the server.
The Filez set is basically broken into a series of 5 classes …
Filez_Uploader along with the accompanying PHP file uploads files or images with some added features, among them the ability to set a maximum file size, set a maximum number of files in the directory, and the option to overwrite another file or not.
Filez_Encoder encodes either a .JPG or .PNG image. It actually uses two separate types of custom encoders based upon ADOBE’s JPGEncoder & PNGEncoder. The JPG encoder comes courtesy of Eugene Zatepyakin. I made a few mods to the PNGEncoder to return a progress event.
Filez_Snapshot ( for Flash 10+ ) uses the FileReference method to save directly without needing any server side technology, so if you just need the ability to save directly from flash you could just use Filez_Encoder and Filez_Snapshot.
Filez_PostByteArray posts ByteArrays to a server. It uses Jonathan Marston’s UploadPostHelper. Unfortunately it doesn’t support a progress event on upload though it should work more than fine for small to medium files.
Filez_Downloader downloads a file from a passed URL.
A few things you might notice about the classes … I’ve opted to use callbacks as opposed to custom events since they seem more reliable and can easily pass arguments back with them.
Here’s a stripped down sample usage of the FilezEncoder class …
import com.patterntest.filez.*;
// create instance ...
var filezEncoder:Filez_Encoder = new Filez_Encoder();
// call Filez_Encoder ...
filezEncoder.go(clip,onProgress,onCompleteCallBack,alertCallBack,{});
// callbacks ...
function onProgress(_percent:String):void {
txtArea.text = int(Number(_percent)*100) +" %";
}
function onCompleteCallBack(_byteArray:ByteArray):void {
txtArea.text = _byteArray.toString()
}
function alertCallBack(_alert:Array):void {
txtArea.appendText(_alert)
}
// begin encoding ...
imageEncoder.beginEncode();
