And then instantiate the appropriate class to the template to be loaded. (Use Autoloader)

require './WPsB_Class_Selector.php';

$args = array(
    'prefix' => "WPsB",
    'suffix' => "Controller",
    'store_name' => 'my_controller'
);

$WPsB_Class_Selector = new WPsB_Class_Selector($args);
$WPsB_Class_Selector->register();

post type is post, template single.php, WPsB_Single_Post_Controller instance is stored in the set_query_var($args['store_name'])

in theme template,

$my_data = get_query_var( 'my_controller' );


echo esc_html( $my_data->foo );

• getter/setter static function
• Corresponding to the attachment', paged, comment_popup`
