Azi am avut nevoie sa afisez 2 dropdown-uri cu ore si minute intr-un template facut cu smarty, si am descoperit ca poti folosi loop-uri in smarty fara sa ai array-uri predefinite in PHP.

{section name=hours start=0 loop=24 step=1}
$smarty.section.hours.index}
{/section}

{section name=minutes start=0 loop=60 step=1}
$smarty.section.minutes.index}
{/section}
