Using JMVC in a different way. This should work on 1.5 but need some changes.

1. Joomla! Component Complexity

but for a complex component how does it work?
Lets think on a ecommerce component

6. software

How to start?

7. ecommerce software

1. Separate your functionalities
2. List functionalities by “group”

11. modular
component
architecture
Component
Component modules (folder)
Module name Module name 2 Module name 3
Controllers Controllers Controllers
Helpers Models Helpers Models Helpers Models
Views Views Views
All components modules work together and build our component.

12. Understand
Modular component
URL
index.php?option=com_ecommerce&module=catalog&task=controller.task
component Component module Task

13. understand
Jcontroller(Legacy)
getInstance
JController::getInstance(‘BASE_NAME’);
1. Will search controller.php file in a base_path
2. If not defined base_path will assume JPATH_COMPONENT
3. Your master controller name should be “BASE_NAME” + “Controller”

14. Examples
Jcontroller(Legacy)
getInstance
Instantiations Master Controller Name Component
JController::getInstance(‘Content’); ContentController com_content
JController::getInstance(‘Users’); UsersController com_users
JController::getInstance(‘Banners’); BannersController com_banners

15. Understand
Modular component
Bootstrap.php
- Read Configuration from config/module.php
- Check if requested module are exists in folder structure
- Define JPATH_COMPONENT_MODULE with module path
- Define base_path as JPATH_COMPONENT_MODULE from JControllerLegacy
- Use as base_name “COMPONENT” + “MODULE”

16. Understand
Modular component
Logic
index.php?option=com_ecommerce&module=catalog
include Read config.
ecommerce.php bootstrap.php config
module.php
Instantiate Controller
folder
MODULE MODULE MODULE

17. Pseudo Code
Modular component
Bootstrap.php
index.php?option=com_ecommerce&module=catalog
Component = Ecommerce
Module = Catalog
JController::getInstance(
‘EcommerceCatalog’,
array(
‘base_path’ => JPATH_COMPONENT_MODULE
)
);

18. File system
Default component
architecture
Attributes for Customers, Products ???
What relations between controllers ???
How to start to understand???
Questions?!

19. File system
Modular component

20. File system
Modular component

Attributes for products
Products Management
Tags for products

21. Understand
Modular component
Module file system
Repository of component modules
Component Module Name
Sub Controllers from Catalog Component Mod.
Helpers from Catalog Component Module
Models from Catalog Component Module
Tables from Catalog Component Module
Views from Catalog Component Module
Master Controller

22. Code
Modular component
Standards
Component + Module + “Controller” + Controller Name
Component + Module + “Helper”
Component + Module + “Model” + Model Name
Component + Module + “Table” + Table Name
Component + Module + “View” + View Name
Component + Module + “Controller”

23. Code
Modular component
Standards
EcommerceCatalogControllerTags
EcommerceCatalogHelper
EcommerceCatalogModelTags
EcommerceCatalogTableTags
EcommerceCatalogViewTags
EcommerceCatalogController

24. Build your
Modular component
Example
This is a sample concept for development a complex software as a Joomla! component.
I’ve not interesting on continue development of this example.
The example its not fully implemented.
It just for show a better way “thinking out of box” How to build complex components.
If you use it, please feedback to community and share the solutions/problems that
you’ve found by using this architecture.
THANK YOU!
