[Koha-devel] Use of TMPL_IF EXPR

[Owen Leonard]

> Is it a performance worry or a security worry?

What I know is that the EXPR syntax sometimes leads to lines like this
in the error log:

"EXPR:at pos 25: non-initialized variable loggedinusername"

This happens when one of the variables being checked by the EXPR
doesn't exist. So in this case the template is saying:

 <!-- TMPL_IF EXPR="OpacNav||loggedinusername" -->

...and in this case no one is logged in.

I don't know what the ramifications are beyond junk in the error log.
