Note: This manual is for osCommerce v4.


Basic Provisions:

1. All extensions must be placed in separate folder.

2. The class file name must be the same as the folder name.

3. Templates must be placed in folder 'views'.

*** Widgets ***

if you want to use widgets in extensions

1. Add method getWidgets with $type parameter and describe widgets in array

example:

return [

           [

               'name' => 'CustomerLoyalty\ShoppingCart', 'title' => 'Customer Loyalty Info Box', 'description' => '', 'type' => 'cart',

           ],

       ];

in this case ShoppingCart (in subfolder \ShoppingCart) is widget ( ShoppingCart.php) can be used in customizing Themes

2. to show additional settings for widget use method showSettings

example:

   public static function showSettings($settings){

       return self::begin()->render('settings.tpl', ['settings' => $settings]);

   }

*** Bootstrap ***

if you want to use personal controllers

1) Create class in file named Bootstrap.php and place in root directory of your extension

use yii\base\Application;

use yii\base\BootstrapInterface;

class Bootstrap implements BootstrapInterface {

   public function bootstrap($app) {

       \Yii::setAlias('@your-extension-alias', dirname(__FILE__));

       if ($app instanceof \yii\web\Application) {

           if ($app->id == 'app-frontend') {

               $app->controllerMap = array_merge($app->controllerMap, [

                   'frontend-controller' => ['class' => 'common\extensions\your-extension\frontend\controllers\your-controller'],

               ]);

           } elseif ($app->id == 'app-backend') {

               $app->controllerMap = array_merge($app->controllerMap, [

                   'backend-controller' => ['class' => 'common\extensions\your-extension\backend\controllers\your-controller'],

               ]);

           }

       }

   }

}

2) enable your extension and try run index action https://yoursite/frontend-controller
