Solution 1:

I think you are missing one condition here

you have only

if($ret === false) {
    die('There was an error writing this file');
}

try to add the else and see

if($ret === false) {
    die('There was an error writing this file');
} else {
  header('Location: ' . $_SERVER['HTTP_REFERER']);
}
