Fix 'Server responded with 0 code' on new uploader #5

Currently the new uploader code successfully uploads the file, however it returns "Server responded with 0 code" and does not take the user to the uploaded file nor does it return a link the user can follow at all.

This poses a problem as the file is uploaded and stored on server but there is no way to access it.

Update:
Coding JSON into the new uploader code as shown below now seems to work and pass a HTTP 200 into the user client.

        $droploaddata = '{ "Location": "https://i.zxicar.us/' . $newfilename . '" }'; 
        header('Content-type: application/json');
        echo $droploaddata;
        return;

NEW PROBLEM:
The client doesn't seem to understand the returned value and redirects the user client to undefined instead. Need to find a way to overcome this.
