Hello. I have been trying to make a widget that has an upload form. The widget would be used to upload images/pdf's to the selected folder (the admin will choose which folder to upload to when they add the widget to the page.)

I got the widget to display the form, and everything looks good. The error I get is when I try to submit it. For some reason, I cant get the upload to work.

GalleryUpload.php

<?php
class GalleryUpload extends Widget {
	static $db = array(
				"Location" => "varchar", //location of folder to upload files to
				"Redirect" => "varchar" //landing page after user uploads image
						);	
				
	static $defaults = array(
		"Location" => "assets/galleries/",
		"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(
		   "FileTypeID"
	   ));
	}
	
	function doForm($data, $form) {
	   $file = new File();
	   $file->loadUploaded($_FILES['FileTypeID']);
	
	   // Redirect to a page thanking people for registering
	   Director::redirect($this->Redirect);
	}
}
?>
