Hi all,

I'm using the GroupedBy method in the templates to group a set of data by a Y-m-d formatted date. All works fine, except that I'd like to further format the index value. For example, here's how I'm using it currently:

<% loop GroupedData.GroupedBy(Day) %>
	<h2>$Day</h2>
	<% loop Children %>
		...
	<% end_loop %>
<% end_loop %>

Where (Day) relates to the following function:

public function getDay() {
	return date('Y-m-d',strtotime($this->ActivityStartDateTime));
}

Obviously the title then renders as a Y-m-d date (i.e. 2013-06-26), but what I'd like to do is to manipulate the $Day index value, so for example, what I'm looking to achieve is something similar to:

<% loop GroupedData.GroupedBy(Day) %>
	<h2>
		<span class="calendar-icon">
			<span class="month">$Day.FormatMonth</span>
			<span class="day">$Day.FormatDay</span>
		</span>
		$Day
	</h2>
	<% loop Children %>
		...
	<% end_loop %>
<% end_loop %>

... and use a function somewhere to format the $Day value:

public function FormatMonth() {
	return date('m',strtotime($this));
}
public function FormatDay() {
	return date('d',strtotime($this));
}

If there's a way to achieve the above then I'd be grateful for some pointers from someone.

Cheers,

Alex
