CakePHP – View Events

There are several callbacks/events that we can use with View Events. These events are helpful to perform several tasks before something happens or after something happens. The following is a list of callbacks that can be used with CakePHP.

S.No Event Function & Description
1 Helper::beforeRender(Event $event, $viewFile)

The beforeRender method is called after the controller’s beforeRender method but before the controller renders view and layout. This receives the file being rendered as an argument.

2 Helper::beforeRenderFile(Event $event, $viewFile)

This method is called before each view file is rendered. This includes elements, views, parent views and layouts.

3 Helper::afterRenderFile(Event $event, $viewFile, $content)

This method is called after each View file is rendered. This includes elements, views,parent views and layouts. A callback can modify and return $content to change how the rendered content will be displayed in the browser.
