Installation consists of two parts: getting composer package and configuring an application.

Installing an extension

The preferred way to install this extension is through composer.

Either run

php composer.phar require --prefer-dist yiisoft/yii2-smarty

or add

"yiisoft/yii2-smarty": "~2.0.0"

to the require section of your composer.json.

Note that the smarty composer package is distributed using subversion so you may need to install subversion.

Configuring application

To use this extension, simply add the following code in your application configuration:

return [
    'components' => [
        'view' => [
            'renderers' => [
                'tpl' => [
                    'class' => 'yii\smarty\ViewRenderer',
                    //'cachePath' => '@runtime/Smarty/cache',

After configuration is done, you need to create templates in files that have the .tpl extension (or use another file extension but configure the component accordingly). Unlike standard view files, when using Smarty you must include the extension in your $this->render() or $this->renderPartial() controller calls:

return $this->render('renderer.tpl', ['username' => 'Alex']);
