Good Evening UncleCheese,

I would like to learn the trick to make the sortable Enum value you did for ImageGallery module. I have two dataobjects

1. ActivityPage - Class
1. Project - DataObject
2. ActivityPhoto - DataObject

Through your kindness advice before, I can bring two DataObject work in one Page. I would like to have sortable Enum like the one you made within ImageGallery module, which allow user to choose ProjectTitle to upload ActivityPhoto.

Thanks in advance for your advice.

Hi UncleCheese,

The thing is I have two DataObject which already bring to CMS and has many is the relationship beftween those dataobject.

- Project
- ActivityPhoto

I would like to know the trick how to create filter which allow user to select Project Code from Project DataObject before inserting new record for ActivityPhoto.

Once again, thanks for your advice and contribution.


Now i can bring up the filter but it doesn't work properly.


class Activity extends Page {

static $icon = "activities/images/activity";
static $db = array(
static $has_many = array(
'ActivityPhotos' => 'ActivityPhoto',
'Projects' => 'Project'

function getCMSFields() {

$fields = parent::getCMSFields();
$manager = new ImageDataObjectManager(
array('Title' => 'Title'),

$manager->setFilter('ProjectID', 'Choose Project Code', $this->Projects()->toDropdownMap('ID', 'Code'));
$items = new DataObjectManager(
$fields->addFieldsToTab("Root.Content.Projects", $items);
$fields->addFieldToTab("Root.Content.Activity", $manager);
$fields->removeFieldFromTab("Root.Content", 'Photo');

if ($this->Projects()->Count() > 0)
$this->ActivityPhotos()->filter = "ProjectID_" . $this->Projects()->First()->ID;
$manager->setAddTitle("Photos to " . $this->CurrentProjectCode());
$manager->filter_empty_string = false;
return $fields;

function getProjectID() {
return str_replace("ProjectID_", "", $this->ActivityPhotos()->filter);

function CurrentProjectCode() {
return DataObject::get_one("Project", $this->getProjectID())->Code;


class Activity_Controller extends Page_Controller {
