How can I retrieve the compile_id within a smarty3 template?

For example, I wish to reference the compile_id in an {if} block:

You shouldn't do THAT in a template, not with compile_id.
compile_id produces a separate compiled version of the template. Given your example, each of these versions will include the same code, which raises a question of what you really trying to achieve here with different compile_id's.
Even if we step down and discuss cache_id, you don't need to know that either.
You must not base your template logic on outside knowledge. And knowing technical metadata is an outside knowledge.
If you want to change your template behavior from your application code (i.e. by passing special variables you think template is checking), you should really reconsider your application logic.
Probably, you need more than one template. Probably, you didn't read inheritance rules or did not gave them a good thought.
Simple rule is to only work your template from explicit knowledge. From the data you have assigned to it directly. That is, Smarty::assign();…

Hi AnrDaemon,

Thanks for your reply. On reflection I can see that you are correct.

As an afterthought, probably an example givein in the http://www.smarty.net/forums/viewtopic.php?t=25486 may be of use to you.

The one benefit of {extends} versus {include} is that {extends} produces one compiled template for its inheritance chain. (In that mentioned example, 3 template sources will produce one compiled template).

Thanks for the pointer.

I'm glad I posted the question that I did. Although my original thinking arose from a flaw in my conceptualisation at the "project level" and I don't actually need to do anything equivalent to what I was asking for, I can see that template inheritance would help parts of my design. This includes the part whose faulty planning spurred my question
