I am using the following code to pull 2 children of the StaffHolderpage into the Homepage.

Page.php:

function ChildrenWithLimit($limit = 2) { 
return DataObject::get('Page', "ParentID = $this->ID", '', '', $limit); 
}

Homepage.ss:


<% control Page(about-us) %> 

  <ul id="StaffList">
   <% control ChildrenWithLimit %> 

      <li>
        <div class="staffname"><a href="$Link">$Title</a></div>
        <div class="staffphoto">$Photo</div>
        <div class="staffdescription"><p>$Content.FirstSentence</p></div>
      </li>
    <% end_control %>
<% end_control %>

But what I hope to do, is to randomly choose 2 of these. Is this possible? how would it be done? Any help would be much appreciated.

Hi
Using "RAND()" for the sorting should do the trick. Eg.

return DataObject::get('Page', "ParentID = $this->ID", 'RAND()', '', $limit);
