Functions

Each Smarty tag either prints a variable or invokes some sort of function. Functions are processed and displayed by enclosing the function and its attributes into delimiters like so: {funcname attr1="val" attr2="val"}.

{config_load file="colors.conf"}

{include file="header.tpl"}

{if $highlight_name}
    Welcome, <font color="{#fontColor#}">{$name}!</font>
{else}
    Welcome, {$name}!
{/if}

{include file="footer.tpl"}

Both built-in functions and custom functions have the same syntax within templates.

Built-in functions are the inner workings of Smarty, such as {if}, {section} and {strip}. They cannot be modified.

Custom functions are additional functions implemented via plugins. They can be modified to your liking, or you can add new ones. {html_options} and {popup} are examples of custom functions.
