Si usa per trasformare una variabile in maiuscolo.
Example 5.21. upper
<?php $smarty = new Smarty; $smarty->assign('articleTitle', "If Strike isn't Settled Quickly it may Last a While."); $smarty->display('index.tpl'); ?>
Dove index.tpl è:
{$articleTitle} {$articleTitle|upper}
Questo stamperà:
If Strike isn't Settled Quickly it may Last a While. IF STRIKE ISN'T SETTLED QUICKLY IT MAY LAST A WHILE.
