In the CMS I need the AssetAdmin to show a custom folder. I might be going around this the wrong way. I'm try to decorate AssetAdmin.

In my _config.php

I've got

Object::add_extension('AssetAdmin', 'MemberAssets');

Then MemberAssets is


class MemberAssets extends DataObjectDecorator {
   function init() {
         echo 'init happening - maybe two lots of data decoratoring does not work';

    * Return the entire site tree as a nested UL.
    * @return string HTML for site tree
   public function SiteTreeAsUL() {

      $obj = singleton('Folder');
      $obj->setMarkingFilter('ClassName', ClassInfo::subclassesFor('Folder'));
      $obj->markPartialTree(30, null, "ChildFolders");

      if($p = $this->currentPage()) $obj->markToExpose($p);

      // getChildrenAsUL is a flexible and complex way of traversing the tree
      $siteTreeList = $obj->getChildrenAsUL(
         '"<li id=\"record-$child->ID\" class=\"$child->class" . $child->markingClasses() . ($extraArg->isCurrentPage($child) ? " current" : "") . "\">" . ' .
         '"<a href=\"" . Controller::join_links(substr($extraArg->Link(),0,-1), "show", $child->ID) . "\" class=\"" . ($child->hasChildFolders() ? " contents" : "") . "\" >" . $child->TreeTitle() . "</a>" ',

      // Wrap the root if needs be
      $rootLink = $this->Link() . 'show/root';
      $baseUrl = Director::absoluteBaseURL() . "assets/";
      if(!isset($rootID)) {
         $siteTree = "<ul id=\"sitetree\" class=\"tree unformatted\"><li id=\"record-root\" class=\"Root\"><a href=\"$rootLink\"><strong>EXTENDED{$baseUrl}</strong></a>"
         . $siteTreeList . "</li></ul>";

      return $siteTree;


I've got init happening - maybe two lots of data decoratoring does not work showing.

Does any have ideas about what I've doing wrong? or there another solution to my problem ?

I've been trying the same. But yeah, the SiteTreeAsUl extend doesn't work. Have you found a solution yet?

I think it's easier to just set the rootfolder, but haven't really found out yet how to.

Yes I did solve it.

What I've got is

class MemberAssets that extends AssetsAdmin

Then I've got some like

public function SiteTreeAsUL() {
       if(Permission::checkMember(Member::currentUser(), "ADMIN")) {
          return $this->AdminSiteTreeAsUL();
       } else {
          return $this->UserSiteTreeAsUL();


Then tidy up the CMS menu in the _config.php I've got

Director::addRules(100,array('admin/files/$Action/$ID/$OtherID' => 'MemberAssets'));

CMSMenu::remove_menu_item('MemberAssets');//this seems to be a bit hack but it works
CMSMenu::add_link('AssetAdmin', 'Files', 'admin/files', $priority = 2);

I hope that helps
