Widgetizing application layouts

As mentioned earlier, we have the option of creating template files inside a theme or a plugin. Here, we are going to create the templates inside the plugins folder to improve flexibility. So, let's begin the process by creating another plugin named WPWA Theme Manager. Create a folder named wpwa-theme and define the main plugin file as class-wpwa-theme.php with the usual plugin definitions. Next, we can update the constructor code as follows to register the widgetized area for the home page:

class WPWA_Theme {

  public function __construct() {
    $this-> register_widget_areas();
  }
  public function register_widget_areas() {
    register_sidebar(array('name' => __('Home Widgets','wpwa'),'id' => 'home-widgets','description' => __('Home Widget Area', 'wpwa'),'before_widget' => '<div id="one" class="home_list">','after_widget' => '</div>','before_title' => '<h2>','after_title' => '</h2>'));
  }
}
