AddBinaryData Issue

Unity Engine
1

I have a Byte array delcared:

public Byte[] clipArray;

After filling the array, I post it to a web form like this:

string url = "removed for privacy/security";
		WWWForm form = new WWWForm();
		form.AddBinaryData("soundArray", clipArray);
		Debug.Log(clipArray.Length);
		WWW www = new WWW(url, form);
        StartCoroutine(WaitForRequest(www));

IEnumerator WaitForRequest(WWW www)
    {
        yield return www;

        // check for errors
        if (www.error == null)
        {
            Debug.Log("WWW Ok! - result: " + www.data);
        } else {
            Debug.Log("WWW Error: "+ www.error);
        }    
    }

On the php side, I use $_REQUEST to get the array:

$soundFileArray = ($_REQUEST["soundArray"]);
$soundFileName = "sound.wav";

$fh = fopen($soundFileName, 'w');
fwrite($fh, $soundFileArray);
fclose($fh);

However, when I run the program, the sound.wav file is empty. The byte array doesn’t seem to be passed. What am I doing wrong?

In your PHP file you must check for $_FILES and not $_REQUEST to read your uploaded binary/file.

Thank you! I’m new to PHP. I’m going to look into using $_FILES now.
