Loadvars.send to php problem

1

I’m having an issue trying to use the loadvars.send to send a string into php, everytime i try and run the script it comes up saying that the variable is an undefined index. I’m using something similar to this:


function sendData() {
var output:LoadVars = new LoadVars();
output.img = "hello"
output.send("../saveBitmap.php", "output", "POST");
}

and the php picking it up is


$img = $_POST['img'];
echo $img;

anyone able to help out on this one???
