Smarty Template Engine

Smarty is a template engine for PHP that facilitates the separation of presentation from application logic. Hazaar MVC supports Smarty (.tpl) as a first-class citizen.

Basic Syntax

Smarty uses curly braces {} for logic and variables.

<h1>Hello, {$name}!</h1>

{if $user.is_logged_in}
    <p>Welcome back, {$user.name}!</p>
{else}
    <a href="/login">Log In</a>
{/if}

<ul>
    {foreach $items as $item}
        <li>{$item}</li>
    {/foreach}
</ul>

View Helpers

Hazaar MVC View Helpers are automatically enabled in Smarty templates. If you initialize a helper in your controller:

// In Controller
$this->view->addHelper('Form');

You can use it directly in your Smarty template as an object:

{$form->open()}
    {$form->input('username')}
{$form->close()}

Custom Functions

You can register custom PHP functions in your controller to be used within your Smarty views.

1. Register in Controller:

$this->view->registerFunction('myFunc', function($param) {
    return "Processed: " . strtoupper($param);
});

2. Call in Smarty:

{myFunc param="test value"}

Layouts

When creating a layout file in Smarty, use the special {layout} function to render the inner view content.

<!DOCTYPE html>
<html>
    <head>
        <title>{$title}</title>
    </head>
    <body>
        <div class="container">
            <!-- Render the main view here -->
            {layout}
        </div>
    </body>
</html>
