Postfilters
Template postfilters are PHP functions that your templates are ran through
after they are compiled. Postfilters can be either
registered or loaded
from the plugins directory by using
load_filter() function or by
setting
$autoload_filters
variable. Smarty will pass the compiled template code as the first
argument, and expect the function to return the result of the
processing.

$smarty->register_postfilter("add_header_comment");
$smarty->display("index.tpl");
