I am trying to get the location from static $db for GalleryUpload, in GalleryUpload_Controller. Here is the code:

class GalleryUpload extends Widget {
	static $db = array(
				//"Page" => "varchar", //page name
				"Location" => "varchar", //location of folder to upload files to                          <-- this is the location
				"Redirect" => "varchar" //landing page after user uploads image
	static $defaults = array(
		"Location" => "new-gallerypage/",
		"Redirect" => "thank-you-page/"
	static $title = "Gallery Upload";
	static $cmsTitle = "Gallery Upload";
	static $description = "Display an upload box for visitors to upload files";
	function getCMSFields() {
			return new FieldSet(
								new TextField("Location", "Set the location for files to be saved to"),
								new TextField("Redirect", "Landing page for users, after they upload a file")
	function Form() {
		$controller = new GalleryUpload_Controller($this);
		return $controller->Form();
	function DescriptionSegment() {
		if(!class_exists("GalleryPage")) {
			return _t("LatestPicturesWidget.NOCLASS","You don't have the Gallery module installed, which is required by this widget.");
		return parent::DescriptionSegment();

class GalleryUpload_Controller extends Controller {
	protected $widget;
	function __construct($widget = null) {
		if($widget) $this->widget = $widget;
	function widget() {
		if($this->widget) return $this->widget;
		else if(is_numeric($this->urlParams['ID'])) return $this->widget = DataObject::get_by_id('Widget', $this->urlParams['ID']);
		else user_error('No widget selected', E_USER_ERROR);
	function Link() {
		if($this->widget()) return $this->class . '/' . $this->widget()->ID;
		else return $this->class . '/';
	function Form() {
	   return new Form($this, "Form", new FieldSet(
		   new SimpleImageField (
			   $name = "FileTypeID",
			   $title = "Upload your image"
	   ), new FieldSet(
	   // List the action buttons here - doform executes the function 'doform' below
		   new FormAction("doForm", "Submit")
	   // List the required fields here
	   ), new RequiredFields(
	function doForm($data, $form) {
	   $file = new File();
	   $location = "/galleries/";// . $this->Widget->GalleryUpload->Location;               <-- I need the location from above
	   $file->loadUploaded($_FILES['FileTypeID'], $location );
	   // Redirect to a page thanking people for registering

I've tried several ways, just to see if it would work, but I haven't managed to come up with anything.

How would I get the right location?

Solved: selected it from the database instead.
