ClicShopping\OM is a framework utilizing new features in PHP to improve the performance, security, and modularity of the codebase. Taking advantage of namespaces and autoloading, it is now even easier to add new features and extend existing features without the need to edit core source code files.

The base framework is located in the includes/ClicShopping directory:

Framework             Namespace              Location
Core                  ClicShopping\OM            includes/ClicShopping/OM
Sites                 ClicShopping\Sites         includes/ClicShopping/Sites
Apps                  ClicShopping\Apps          includes/ClicShopping/Apps
Custom                ClicShopping\Custom        includes/ClicShopping/Custom


The framework is built utilizing the PSR-4 standard for autoloading classes from matching namespaces and file paths. Classes are automatically loaded on demand and don't need to be included/required manually.

The base namespace the autoloader watches for is ClicShopping\ and loads the class files located in the includes/ClicShopping/ directory.


Class    File Location

ClicShopping\OM\CLICSHOPPING        includes/ClicShopping/OM/CLICSHOPPING.php
ClicShopping\OM\Db                  includes/ClicShopping/OM/Db.php
ClicShopping\OM\Registry            includes/ClicShopping/OM/Registry.php
ClicShopping\Sites\Shop\Shop        includes/ClicShopping/Sites/Shop/Shop.php
ClicShopping\Apps\VENDOR\APP\APP    includes/ClicShopping/Apps/VENDOR/APP/APP.php

Classes in the framework must declare their namespace as the first PHP code in the file.


    namespace CLICSHOPPING\OM;
    class NewClass {

The full namespace to the above example would be:


and the location of the file would be:


For another class to be able to load ClicShopping\OM\NewClass automatically, it needs to be declared with PHP's use keyword after the namespace of the class and before any other PHP code.


    namespace ClicShopping\OM;
    use ClicShopping\OM\NewClass;
    class AnotherNewClass {
       public function __construct() {
         $NewClass = new NewClass();

The framework autoloader (ClicShopping\OM\CLICSHOPPING::autoload()) is registered as an autoloader in includes/application_top.php and is automatically initialized in all main PHP files that include the application_top.php file.
Template files do not need to have a namespace set, but still need to reference framework classes that it uses:


    use ClicShopping\OM\HTML;
    echo HTML::outputProtected('Hello World!');

More information about namespaces can be found at the PHP Namespace documentation page.



Sites are registered in the framework to initialize and apply environment parameters specific to that site.
The available sites in the core are:

Site                    Controller
Shop (default)          ClicShopping\Sites\Shop\Shop
Admin                   ClicShopping\Sites\ClicShoppingAdmin\Admin

Sites are registered and retrieved as follows:

    use ClicShopping\OM\CLICSHOPPING;
    $site = CLICSHOPPING::getSite();

Custom Directory

To customize a core source file, copy it to this directory matching the directory structure of the original file.

For example,

- to make custom changes to ClicShopping/OM/Session/File.php

- copy the complete file to ClicShopping/Custom/Session/File.php and perform your changes to this new file.


Although the custom class is copied to a Custom directory, it must retain the original Core namespace. Due to this, copied classes cannot extend the original class in the Core namespace.


ClicShopping\Custom\Conf                          Configuration setting
ClicShopping\Custom\Sites\Shop (default)          Shop classes
ClicShopping\Custom\OM                            OM classes
ClicShopping\Custom\Schema                        Database file installation 



Apps are self-contained packages that add new or extend existing features through modules and hooks. Apps reside in their own directory and do not need to edit core source code files.
Apps are located in the following directory:

Namespace                                      Location
ClicShopping\Apps\VENDOR\APP    includes/ClicShopping/Apps/VENDOR/APP

Apps also have a public directory for public accessible files such as stylesheets, javascript, and images, located at:


More information is available in the Apps chapter.



Services are portions of the online store that do not directly relate to the customer purchasing a product, but can be helpful in setting up the


Services are available in Shop and ClicShoppingAdmin. it can use everywhere inside the site.



Service for the mail


  namespace ClicShopping\Service\Shop;

  use ClicShopping\OM\Registry;

  use ClicShopping\OM\Mail as MailClass;

  class Mail implements \ClicShopping\OM\ServiceInterface {

    public static function start() {

      if (is_file(CLICSHOPPING_BASE_DIR . 'OM/Mail.php')) {
        Registry::set('Mail', new MailClass());

        return true;
      } else {
        return false;

    public static function stop() {
      return true;

How to call inside a file :

$CLICSHOPPING_Mail = Registry::get('Mail');
