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

<?php
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;
      parent::__construct();
   }
   
   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(
       "FileTypeID"
    ));
   }
   
   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
    Director::redirect($this->Redirect);
   }
}
?>

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.
