Smarty is a web template system written in PHP. Smarty is primarily promoted as a tool for separation of concerns.[1] Smarty is intended to simplify compartmentalization, allowing the front-end of a web page to change separately from its back-end. Ideally, this lowers costs and minimizes the efforts associated with software maintenance.

Smarty generates web content through the placement of special Smarty tags within a document. These tags are processed and substituted with other code. Tags are directives for Smarty that are enclosed by template delimiters. These directives can be variables, denoted by a dollar sign ($), functions, logical or loop statements. Smarty allows PHP programmers to define custom functions that can be accessed using Smarty tags.

Smarty example[edit]

Since Smarty separates PHP from HTML, there are two files — one contains the presentation code: an HTML template, including Smarty variables and tags - {$title_text|escape} {$body_html} - which might look like this:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "DTD/xhtml1-strict.dtd">
<html>
<head>
   <title>{$title_text|escape}</title>
   <meta http-equiv="content-type" content="text/html; charset=utf-8" />
</head>
 
<body> {* This is a little comment that won't be visible in the HTML source *}
 
{$body_html}
 
</body><!-- this is a little comment that will be seen in the HTML source -->
</html>

The business logic to use the Smarty template above could be as follows:

define('SMARTY_DIR', 'smarty-2.6.22/' );
require_once(SMARTY_DIR . 'Smarty.class.php');
 
$smarty = new Smarty();
$smarty->template_dir = './templates/';
$smarty->compile_dir = './templates/compile/';
 
$smarty->assign('title_text', 'TITLE: This is the Smarty basic example ...');
$smarty->assign('body_html', '<p>BODY: This is the message set using assign()</p>');
 
$smarty->display('index.tpl');
