Smarty 2.x and 3.0

Template variables start with the dollar($) sign. They can contain numbers, letters and underscores, much like a PHP. You can reference arrays by index numerically or non-numerically. Also reference object properties and methods.

1. Config file variables are an exception to the $dollar syntax and the $smarty.config variable.

2. { * display the server variable "SERVER_NAME" ($_SERVER['SERVER_NAME'])*}
{$smarty.server.SERVER_NAME}

3. Math and embedding tags:

4. Defining Arrays:

5. Smarty "dot" syntax (note: embedded {} are used to address ambiguities):

This is a short-hand version of the {assign} function. You can assign values directly to the template, or assign values to array elements too.

Example1 :

{$myname="Sunil"}
My name is : {$myname}

Example2 :

{assign var=myname value="Sunil"}
My name is : {$myname}

Example3 :

{assign "myname"  "Sunil"}
My name is : {$myname}

Most of the functions take attributes that specify or modify their behavior. Attributes to Smarty functions are much like HTML attributes. Static values don't have to be enclosed in quotes, but it is recommended for literal strings. Variables may also be used, and should not be in quotes. Some attributes require boolean values (true or false). These can be specified as either unquoted true, on, and yes, or false, off, and no.

Example1 :

$states_name = array("Odisha","Andhra Pradesh","Delhi","Punjab");
$state_index=array(0,1,2,3);
<select>
{html_options options=$states_name selected=$state_index.3}
</select>

Example2 :

{html_select_date display_days=no}
