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.
