Este es usado para convertir a mayusculas una variable.
Example 5.21. upper
<?php
$smarty->assign('articleTitle', "If Strike isn't Settled Quickly it may Last a While.");
?>
Donde index.tpl es:
{$articleTitle}
{$articleTitle|upper}
Esta es la Salida:
If Strike isn't Settled Quickly it may Last a While. IF STRIKE ISN'T SETTLED QUICKLY IT MAY LAST A WHILE.
