    include template based on nubmer of children Link to this post

    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');
