Selecting side bar blocks per page.

I have a sidebar on my website which contains a set of blocks. These blocks are basically just a single link (i.e. "Download White Papers" or "Request a Demo"). Some pages need to have some of the blocks visible, other pages have different blocks. After reading [url][/url] and [url][/url] it seemed as though it would be fairly simple to create a new page type called SideBarItem, and add a has_many to the Page class.

I'm having a couple of problems though. First off, if I click "add" in the complex table field, I get an error stating that the function SideBarItem() is not defined. I can still however create pages of type SideBarItem in the site tree and get them to show up in the table though. Unfortunately when I do this, the check box to associate it with the page is disabled and cannot be clicked.

Any thoughts would be appreciated (I am a newbie- sorry..)

My code:


class Page extends SiteTree {
public static $has_many = array( 'SidebarItems' => 'SidebarItem' );

public function getCMSFields() {
$fields = parent::getCMSFields();

$tablefield = new HasManyComplexTableField(
'Title' => 'Title',

$tablefield->setAddTitle('A SidebarItem');
$fields->addFieldToTab('Root.Content.SidebarItems', $tablefield);

return $fields;



class SidebarItem extends Page {

class SidebarItem_Controller extends Page_Controller {


Obviously nothing special for SidebarItem..
