You don't need to set an action, you can simply give it a name. So you form would look something like this:

<form name="submit" method="post" enctype="multipart/form-data">
  <label for="file">Filename:</label>
  <input type="file" name="file" id="file"><br>
  <input type="submit" name="submit" value="Submit">
</form>

Then your helper.php :

class ModHelloWorldHelper {
    public static function submit($file) {
        // some code goes here
    }
}

Then your mod_helloworld.php (which calls the function in the helper.php):

$input = new JInput;
$post = $input->getArray($_POST);

if ($post["submit"]) {
    modHelloWorldHelper::submit($file);
}

Please note that you will of course have to make a few changes to suits your needs as the code above is just there to give you a small head start
