Widgetizing application layouts

As mentioned earlier, we have the option of creating template files inside a theme or a plugin. Here, we will create the templates inside the plugins folder to improve flexibility. So, let's begin the process by creating a file called class-wpwa-theme.php within the root directory of our main plugin and including it in the class-wpwa-portfolio-manager.php file. 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>'
    ));
