Combining Modifiers

You can apply any number of modifiers to a variable. They will be applied in the order they are combined, from left to right. They must be separated with a | (pipe) character.

<?php

$smarty->assign('articleTitle', 'Smokers are Productive, but Death Cuts Efficiency.');

where template is:

{$articleTitle}
{$articleTitle|upper|spacify}
{$articleTitle|lower|spacify|truncate}
{$articleTitle|lower|truncate:30|spacify}
{$articleTitle|lower|spacify|truncate:30:". . ."}
