Template variables start with the $dollar sign. They can contain numbers,
letters and underscores, much like a
PHP variable.
You can reference arrays
by index numerically or non-numerically. Also reference
object properties and methods.
Config file variables
are an exception to the $dollar syntax
and are instead referenced with surrounding #hashmarks#, or
via the
$smarty.config variable.
Example 3-2. Variables
{$foo} <-- displaying a simple variable (non array/object)
{$foo[4]} <-- display the 5th element of a zero-indexed array
{$foo.bar} <-- display the "bar" key value of an array, similar to PHP $foo['bar']
{$foo.$bar} <-- display variable key value of an array, similar to PHP $foo[$bar]
{$foo->bar} <-- display the object property "bar"
{$foo->bar()} <-- display the return value of object method "bar"
{#foo#} <-- display the config file variable "foo"
{$smarty.config.foo} <-- synonym for {#foo#}
{$foo[bar]} <-- syntax only valid in a section loop, see {section}
{assign var=foo value='baa'}{$foo} <-- displays "baa", see {assign}
Many other combinations are allowed
{$foo.bar.baz}
{$foo.$bar.$baz}
{$foo[4].baz}
{$foo[4].$baz}
{$foo.bar.baz[4]}
{$foo->bar($baz,2,$bar)} <-- passing parameters
{"foo"} <-- static values are allowed
{* display the server variable "SERVER_NAME" ($_SERVER['SERVER_NAME'])*}
{$smarty.server.SERVER_NAME}
Request variables such as $_GET,
$_SESSION, etc are available via the
reserved $smarty variable.
