Joomla 11.1 JView

Description

JView is an abstract class which provides the basic functionality for Joomla's MVC design pattern. You need to write your own concrete View classes, to make full use of the functionality. Learn more

The Joomla MVC Design Pattern

Model-View-Controller (MVC) is a set of design patterns, that are used to separate the different layers of your application.

  • The View displays the data of the model by passing it to a template. The view object can therefore access the data of the model. Joomla implements the basic functionality in the abstract JView class.
  • The Model stores the data of the application, and contains the business logic. Joomla implements the basic functionality in the abstract JModel class.
  • The Controller handles the user requests and evokes the model and the views to change it's state. Joomla implements the basic functionality in the JController class.
