Introduction

It is important to make the separation between display (presentation) design and creating the application. Simply, you can create content first without having to consider display (the Presentation Layer). Or, you can design the look without the design of the application code. At first, Smarty wants to act as a "Template Engine". However, now they claim that it is not only a template engine; Smarty is a template/presentation framework. The Word Framework that refers to Smarty is no longer a simple tag of a template engine. He has focused on how to help you make a high-performance, scalable, secure and flexible application.

What is Smarty

Smarty is a "Template Engine" which separates Presentation Layer from the Business Layer and provides manageable wait exchange data between the two layers.

Ok, in the next article, we will try to test it.

First Program in Smarty

Create a file named "test.tpl" within the template folder. Enter the following code:

<html>

<head>

<title>{$title}</title>

</head>

<body>

{$hello}

</body>

</html>

Next, create a PHP file named "test.php" within www/test/smarty. Enter the following code:

<?php

require 'Smarty/libs/Smarty.class.php';

$smarty = new Smarty;

$smarty->assign('title','Hello World');

$smarty->assign('hello','Hello World, this is my first Smarty!');

$smarty->display('test.tpl');

?>

Output

Smarty Template Basic

We will see something basic about Smarty. You must be familiar with them.

Comment

Comments are statements added in code to explain something or to provide a note. In Smarty we can use comments such as:

<html>

<body>

{* this template use Smarty! *}

{* put any code at here! *}

</Body>

</html>

Method

Such as with other classes, Smarty has methods. We can use a Smarty method to help our job. I just want to show a little of that and then we will talk later. See:

<html>

<Body>

{config_load file="colors.conf"}

{include file="header.tpl"}

{if $somebody}

Welcome, {$name}

{else}

Who are you?!?

{/if}

</Body>

</html>

Attribute

Such as HTML, in Smarty a tag/command can have one or more attributes. Example:

<html>

<Body>

{include file="footer.tpl"}

</Body>

</html>

Variable

<html>

<Body>

{funk var="test $foo test"}

{funk var="test $foo_bar test"}

{funk var="test $foo[0] test"}

{funk var="test $foo[bar] test"}

{funk var="test $foo.bar test"}

{funk var="test `$foo.bar` test"}

</Body>

</html>

Mathematics

<Body>

{$foo * $bar}

{$foo + $bar}

</Body>

Associative array in Smarty

Build a template by creating a file named "test.tpl" within a template. Enter the following code:

<html>

<head>

<title>{$title}</title>

</head>

<body>

id : {$contact.id} <br>

name : {$contact.name} <br>

email : {$contact.email} <br>

phone : {$contact.phone} <br>

</body>

</html>

Next, create a file named "test.php" and enter the following code:

<?php

require 'Smarty/libs/Smarty.class.php';

$smarty = new Smarty;

$smarty->assign('title','Contact Detail');

$smarty->assign('contact',array('id'=>1,

'name'=>'Vinod Kumar',

'email'=>'[email protected]',

'phone'=>'8506800799'

));

$smarty->display('test.tpl');

?>

Create Object in Smarty

We will see how to access data from a class.

Build a template by creating a file named "test.tpl" within the template. Enter the following code:

<html>

<head>

<title>{$title}</title>

</head>

<body>

id : {$contact->id} <br>

name : {$contact->name} <br>

email : {$contact->email} <br>

phone : {$contact->phone} <br>

</body>

</html>

Next, create a file named "test.php" and enter the following code:

<?php

require 'Smarty/libs/Smarty.class.php';

class Contacts{

var $id = "1;"

var $name = 'Vinod kumar';

var $email = '[email protected]';

var $phone = '8506800799';

}

$contact = new Contacts;

$smarty = new Smarty;

$smarty->assign('title','Contact Detail');

$smarty->assign('contact',$contact);

$smarty->display('test.tpl');

?>
