[ 38 ] Chapter 2 Using the factory( ) method In our current action_index() method, we are creating the View object using the factory() static method. The method accepts a second argument of an array that is then accessible in the view file. A few small changes will turn our static welcome page into a dynamic view. Time for action – Passing data via the factory method To create and output data from our controller, we will need to modify both the controller action and the view file.

This could also be written with the same outcome as: public function action_index() { $view = View::factory('welcome'); $view->set('site_name', 'Egotist'); $view->set('random', rand(1,10)); $this->request->response = $view; } Using the set() method makes it easy to read code, and can be a good pattern to use when the values for the view variables will be computed elsewhere, and then set once the view is instantiated. Again, there were no changes necessary to the view file because the same names were used for our view variables.

Php, and is located in application/classes/controller/, meeting the first and second rules as outlined above. The class is named Controller_Welcome, where welcome is the filename capitalized, and Controller_ is prepended, passing the third rule. The Controller_Welcome class extends Controller, passing the last rule. [ 35 ] Using Views and Controllers The next line of code reads: public function action_index() This creates a new controller action named index.
