Smarty: Functions

Every Smarty tag either prints a variable or invokes some sort of function. These are processed and displayed by enclosing
the function and its attributes within delimiters like so: {funcname attr1='val1' attr2='val2'}.

Example function syntax

{config_load file='colors.conf'}
{include file='header.tpl'}
{insert file='banner_ads.tpl' title='Smarty is cool'}
{if $logged_in}
Welcome, {$name}!
{else}
hi, {$name}
{/if}
{include file='footer.tpl' ad=$random_id}
