for a menu i parse the third level from sitetree. Every third level item is related to some dataobjects. These dataobject are nested under the related menuitem (<% control getFirmenforBanner %>) and link to the same template (e.g. What i want to do:

If the show parameter from URL is similar to the $ID within <% control getFirmenforBanner %>, then i want to write a "class="current" to the <li>.

Can anybody help?

<ul class="menu">
          <% control Menu(3) %>	  
          <li class="sublevel1"><a href="{$Link}" title="weiter in $Title.XML page" class="$LinkingMode"><span>$MenuTitle</span></a>
          <% if LinkOrCurrent = current %>
            <% control getFirmenforBanner %>
            <li class="sublevel2"><a href="{$URLSegment}/show/$ID">$Firmenname</a></li>
              <% end_control %>
              <% end_if %>
          <% end_control %>

Hi Carsten,

I had a similar problem trying to show the "current" image in a custom gallery page I built. Templates currently do not have this ability. What I did in the end was this:

class GalleryPage extends Page {

static $has_many = array (
'Images' => 'GalleryPage_Image'


class GalleryPage_Controller extends Page_Controller {


class GalleryPage_Image extends Image {

static $has_one = array(
'GalleryPage' => 'GalleryPage',

function IsCurrent() {
return (Director::urlParam("ID") == $this->ID) ? true : false;


Basically, as the control loops through Images, the Image has a check against the URL. In my template:

<% control Images %>
<div <% if IsCurrent %>class="current"<% end_if %>>
<a href="$CurrentPage.URLSegment/showImage/$ID" onclick="return false;">
<img src="$URL" alt="$Title" />
<% end_control %>

Some code has been removed for clarity, so copy and paste won't work. Hope this helps.

Hi Dave,

very good idea. But i have already solved it by altering my control. I have just added the id to my DataObjectSet.

$firmen = new DataObjectSet();
			 $urlid = Director::urlParam('ID'); // URL PARAMETER VERARBEITEN
			 $count = -1;
			 foreach($result as $row) { 
				if($row['ID'] == $urlid){
					$row['status'] = ' current';
				} else {
					$row['status'] = '';
				$firmen->push(new ArrayData($row));

Thanks a lot for your reply.

Greetings from Germany, Carsten.
