I want to achieve a seemingly simple task, however I have been searching the web and the forums here to no avail for more than a week
My problem is this

I have enabled search form in a silverstripe website and have managed to successfully implement the search of dataobjects on the site.

However when the DataObjects(Products), are displayed in the search results I want to be able to link them to the category pages that they belong to. To achieve this I wrote a simple function in the page controller, that will return the category page based on the ID provided.

public function getCategoryPages($theID) {
   return SiteTree::get()->filter('ID',$theID);
}

and I wanted to be able to do this in the template

<% loop $Results %>

               <% if CategoryID %>
            
               <% loop $Top.getCategoryPages($CategoryID) %>
                  <a href="$Link">Link</a>
               <% end_loop %>
               <% end_if %>
<% end_loop %>

The problem is no matter what I do I am not able to pass the correct $CategoryID value to the function. I have tried, almost everything but I am not able to do so, please someone point me in the right direction, it was my understanding that this is possible to do in SilverStripe 3.0 which is the version I am using. I am I trying to do something that is not possible? If so how can I get around this problem? Any help would be greatly appreciated (I have pulled all of my hair out trying to figure this out :( )
