Suppose I have in php file
<?
$tpl->assign('_YEAR',date('Y'));
$tpl->assign('_FOOTER',"This is {$_YEAR}");
?>
and in templeate file
<div class="footer">{$_FOOTER}</div>
---
The current output is
<div class="footer">This is {$_YEAR}</div>
What do I do so that I get
<div class="footer">This is 2012</div>
----
P.S. Year is just an example. This can be any value coming from database.

Please help!

Smarty does not parse assigned variable values for template code.
If you really need it see {eval} http://www.smarty.net/docs/en/language.function.eval.tpl

But this has very bad performance as the compiler must be called for each such variable.
