sort children by Date
26 August 2009 at 2:55am
Hi there,
I want to control over a Pages children on which one every got a field Date. Instead of using the order which is given by drag and drop in the backend, I want to sort the children by the datefield. How do I implement this?

You could add a method to your class, that returns the child pages, sorted by date:
// this method belongs to your Page Class
// or the class that holds the sortable children
public function SortedChildren(){
// $children will be a DataObjectSet
$children = $this->Children();if( !$children )
return null; // no children, nothing to work with// sort the DataObjectSet
// see http://doc.silverstripe.com/doku.php?id=dataobjectset#sorting
$children->sort('Date');// return sorted set
return $children;

Is this function supposed to be posed in the class or in the controller class?

The function has to be in the Controller Class.
then you'll be able to acess your Custom-Sorted Children in the Template via:
<% control SortedChildren %>
$Date
<% end_control %>cheers.

I'm trying to get this to work on DataObject within a Children.GroupedBy control and I'm not getting any results. Anyone tried this?
