There's one problem with using URLVariables: it works on NUL-terminated strings, so if you happen to have a 0 in the compressed data, it will be truncated
Some time ago I wrote a class to post data in multipart format (basically, it does the same the browser does when you have a form with a file input). I used it to send image files, but since the data is binary, it shouldn't matter what kind of file you're sending. So, from the php side you handle it much like an oridnary html form. Text variables will be put in $_POST, and the "files", i.e. the binary data, would be in $_FILES. I had uploaded that class to pastebin and it's still there: http://pastebin.com/f11a897cf I'm re-pasting a use example from another email: =====> An example of use (it's a copy & paste from some worting code, just to give you an idea): import ar.com.califa010.utils.FormData; // getEncodedImg() is a method that returns a JPG as a byteArray var rawJpg:ByteArray = getEncodedImg(); var formData:FormData = new FormData(); var imageMimeType:String = FormData.JPG_FILE; var fileName:String = "imageFile.jpg"; // from the php side, you'll get this data with $_FILES['imageFile'] // rawJpg is the byteArray you want to send // fileName and imageMimeType don't really matter that much // it's supposed to send the name of the original file and the type to hint the server, but // I think you can leave it as is and will have no problems formData.addFile("imageFile", rawJpg, fileName, imageMimeType); formData.addField("sFormat",imgFormat); formData.addField("idImagen",_idImagen); var req:URLRequest = new URLRequest(url); req.method = "POST"; req.contentType = formData.contentType; req.data = formData.getPostData(); var loader:URLLoader = new URLLoader(); configureListeners(loader); loader.load(req); =====> Cheers Juan Pablo Califano 2008/10/3, Benny <[EMAIL PROTECTED]>: > > We are getting closer ;-) > > The code you provided worked for me too. > When I compare my code to yours I notice that I am using the $_POST array > while you are using the PHP input stream.
