In a site I'm building I want different banner images for each section of the site, and so want a page to default it's parents banner if one is not set. I have set up the following code, but I don't see anything on the page

the code is based on [url=]this archived post[/url]

In Page.php

class Page extends SiteTree {
   static $has_one = array(
   'BannerImage' => 'Image'

class Page_Controller extends ContentController {
function getBannerImage() {

$BannerImage = $this->getParentBannerImage($this);
return $BannerImage;

private function getParentBannerImage($CurrentPage){
$Parent = $CurrentPage->Parent;


return $BannerImage;
// We found the current header! Let's return it!
} else {
return $this->getParentBannerImage($Parent);
// We didn't find a header,so we have to call ourselves again

} else {
return false;

In i'll just do something like this:

<div id="banner" style="background:url(<% control getBannerImage %>$URL<% end_control %>)"></div>

So, it's probably something completely obvious...just not to me at the mo!
