This is used to uppercase a variable. This is equivalent to the PHP strtoupper() function.
Example 5-22. upper
<?php$smarty->assign('articleTitle', "If Strike isn't Settled Quickly it may Last a While.");?>
Where template is:
{$articleTitle} {$articleTitle|upper}
Will output:
If Strike isn't Settled Quickly it may Last a While. IF STRIKE ISN'T SETTLED QUICKLY IT MAY LAST A WHILE.
See also lower and capitalize.
