Each Smarty tag either prints a
|
|
<link linkend="language.variables">variable</link> 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"}.

Both built-in functions and custom functions have the same syntax in
|
|
the templates. Built-in functions are the inner workings of Smarty,
|
|
such as <command>if</command>, <command>section</command> and
|
|
<command>strip</command>. 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. <command>html_options</command> and
|
|
<command>html_select_date</command> are examples of custom functions.
