im trying to perform a conditional check to include a different template based on the total number of children. so if there is only one child, display the full entry...if there is more than 1, display a summary list.

my code looks like this:

// model //////////////////////////////////////////////////////

class ExhibitionsHolder extends Page {


public function numChildren(){

return DB::query("SELECT COUNT(*) FROM SiteTree_Live WHERE ParentID = '$this->ID'")->value();



// template code //////////////////////////////////////////////////////////

<% if numChildren == 1 %>
<!-- display only 1 entry -->
<% include ExhibitionPage %>
<% else %>
<% if numChildren == 0 %>
No entries found....
<% else %>
<!-- display summary of all entries -->
<% include ExhibitionList %>
<% end_if %>      
<% end_if %>

this works...however, wondering if there is a better way to do this without having to nest conditional statements.

i tried using else_if...but it did not work.

<% else_if Something %> is supported in SilverStripe, not sure if <% else_if Something == 0 %> is supported though. SSViewer is a very simple parser so most complex tasks are left to your PHP.

If you wanted to clean that out you could rewrite your function to something which used a switch (or if .. else) statement in the PHP function and did a return $this->renderWith('TemplateName');
