Re: [htmltmpl] Template math

[Brian M. <bm...@pa...>]

Yep, I do similar things every day with HTML::Template::Expr.
Like most perl and perl related solutions, you could do this one of several
ways...

You might try using successive <TMPL_IF EXPR="score < x"> statements (which
is rather lengthy, so I won't write it out), or you could try the following:

(For the sake of simplicity, I'll use the 10 star option, just so you can
get the idea)


        <img src="/images/<TMPL_VAR EXPR="int(score / 100)">-stars.gif">


The problem with this is that int() isn't going to be too terribly accurate.
Read the part of the H-T-Expr docs regarding custom functions and you should
be able to handle the inaccuracy by using a rounding function instead of
int().
