Hi Eric,
It sounds like you have hit the dreaded "top level param, not referenced before
use in template loop, so I'll just do nothing" bug... try this somewhere before
your first TMPL_LOOP (say at the top of the file), in your first template:
<!-- H::T BUG: <TMPL_VAR URL_BASE> -->
which _should_ do absolutely nothing useful/harmful to the html output.
However, it will result in H:T actually getting a reference to the URL_BASE
variable.
What you were expecting to happen (ie template variable used in some child
template, when being set at the top-level), is what most people expect to
happen... In my own templates, I have also hit this problem.
This bug is a result of how H::T handles TMPL_LOOP invocations... it basically
does a recursive call of itself, passing the known params from the previous
instance, into this new invocation. Since the previous invocation hasn't
referenced the TMPL_VAR, that value isn't passed into the TMPL_LOOP invocation.
Hope this helps,
Mathew
