How can I access the Component Template ID from within my Component DWT?

Question

In the HTML template for my Component I need to write out the TCM URI of the Component Template:

<!-- Start Component Presentation: {"ComponentID" : "@@Component.ID@@",
                        "ComponentTemplateID" : "@@ComponentTemplate.ID@@" } -->

But unfortunately ComponentTemplate.ID doesn't exist.

How can I access the Component Template ID from within my Component DWT?

Answer 1

I'm afraid you'll have to write a C# TBB (fragment or assembly):

TcmUri templateId = engine.PublishingContext.ResolvedItem.Template.Id;
if (templateId.ItemType == ItemType.ComponentTemplate) {
    Item item = package.CreateStringItem(ContentType.Text, templateId.ToString());
    package.PushItem("ComponentTemplateID", item);
}

You can only access the ComponentTemplate.ID from within a Page DWT layout...

Answer 2

Add a "ComponentTemplateID" parameter to the Template Invocation in the compound template. You can then access this in the same way as package variables.
