I have the following setup. A FacultyPage page type and a Faculty dataobject. A FacultyPage has many Faculty and a Faculty has one Faculty Page. Within the Faculty Page controller I have the following code...

function showfaculty() {
      if($id = Director::urlParam('ID')) { // check to see we have been passed an ID
         $showfaculty = DataObject::get_by_id("Faculty", $id);
         return $this->customise(array('Faculty' => $showfaculty))->renderWith(array('FacultyMember', 'Page'));
      }
   }

This works fine with a url like mysite.com/facultypage/showfaculty/1

My question is how to get the correct facultypage to print in the link? Because it is within a faculty control loop on the FacultyPage.ss page it won't display the url with the facultypage part, nor can I call something like $URLSegment. Here is the template code...

<% control Faculty %>
<tr class="<% if Even %>even<% else %>odd<% end_if %>">
<td><a href="showfaculty/$ID">$FirstName $LastName</a></td>
<td>$Phone</td>
<td class="last"><a href="mailto:$Email">$Email</a></td>
<% end_control %><!-- end of Faculty control -->

I need this part: <a href="showfaculty/$ID"> to print: mysite.com/facultypage/showfaculty/1 not this: mysite.com/showfaculty/1

Any ideas would be a big help, thanks!

You need to overload your Link() method on the Faculty object

function Link()
{
return $this->FacultyPage()->Link("showfaculty")."/".$this->ID;
}

You can also use the $EvenOdd template variable and clean up those if blocks.

Perfect, that's exactly what I needed, and thanks for the tip about the EvenOdd variable - much cleaner!
