Using controller context in a view

Yii views are pretty powerful and have many features. One of them is that you can use controller context in a view. So, let's try it.

Getting ready

Set up a new application using yiic webapp.

How to do it...

Create a controller as follows:

class WebsiteController extends CController
{   
   function actionIndex()
   {
      $this->pageTitle = 'Controller context test';
      $this->render('index');
   }

   function hello()
   {
      if(!empty($_GET['name']))
         echo 'Hello, '.$_GET['name'].'!';
   }
}

Now, we will create a view showing what we can do:

<h1><?php echo $this->pageTitle?></h1>
<p>Hello call. <?php $this->hello()?></p>
<?php $this->widget('zii.widgets.CMenu',array(
'items'=>array(
      array('label'=>'Home', 'url'=>array('index')),
      array('label'=>'Yiiframework home', 'url'=>'http://yiiframework.ru/',
   ),
))?>

How it works...

We are using $this in a view to refer to a currently running controller. When doing it, we can call a controller method and access its properties. The most useful property is pageTitle which refers to the current page title and there are many built-in methods that are extremely useful in views such as renderPartials and widget.
