Add a View to Joomla Site Part

When no task is given in the request variables, the default task will be executed. The default task is display. The JControllerLegacy class has such a task. When display is used, the 'view' variable will decide what will be displayed.


class HelloWorldViewHelloWorld extends JViewLegacy
function display($tpl = null)
// Assign data to the view
$this->msg = 'Hello World';

// Display the view

The view sets up the text to be output and then calls the base display class. JViewLegacy is a base class for a Joomla View. In current example, this method will display data using the tmpl/default.php file.


<h1><?php echo $this->msg; ?></h1>

This template file will be included by the JViewLegacy class. Therefore, here, $this refers to the HelloWorldViewHelloWorld class.
