2. Basic knowledge of HTML, PHP and MySQL
Interest in MVC and CMS frameworks to reduce development
time
A web server with PHP/MySQL installed on it
Joomla! 2.5 package downloaded and installed
◦ it can be downloaded from http://www.joomla.org/download.html
NOTE: This presentation is focused for the beginners in Joomla! and would
cover only a basic overview due to limited time. Further details can be
discussed separately later.
3. An overview of both the
Joomla! Extensions to
understand the
basics, conventions and
structure.
4. What is a module?
◦ Modules are lightweight and flexible extensions
used for page rendering. These modules are often
“boxes” arranged around a component on a typical
page. A well-known example is the login module.
Why should we use a module?
◦ Can work standalone
◦ Good for code reusability
◦ Can work with component for database linking
Conventions
◦ Module name should be in small letters
◦ Module name should have a prefix “mod_”
5.
6. Depends on template
Added in template using below code:
◦ <jdoc:include type="modules" name=“module-positon-
name" />
Can be more than one modules on a page
7. Go to Joomla! Admin Panel
Access Top Menu>Extensions>Template
Manager
Click on options button on the top-right side
of the toolbar
Enable the “Preview module positions”
Go to website front panel and add “?tp=1” to
the url
◦ It will reveal the module positions in a Joomla
template
13. Mod_modulename – module folder
◦ mod_modulename.xml
◦ mod_modulename.php
◦ helper.php: This helper file contains a class to
provide various static functions to perform
operations. It could be used to perform some
calculation or to fetch data from DB.
◦ index.html: It is an empty file and created to
prevent direct access to the directory.
◦ tmpl folder
default.php:
index.html: It is an empty file and created to prevent
direct access to the directory.
14. What is component?
◦ Components are the main functional units of
Joomla!; they can be seen as mini-applications.
◦ A component can contain a module and a plug-in
Why should we use a component?
◦ To manage more functional part or application
◦ To provide backend handling to a front-end
functionality
Conventions
◦ Component name should be prefixed by “com_” e.g.
com_componentname
◦ Component name should start with small letters
15. Depends on template
Added in template using below code:
◦ <jdoc:include type="component" />
Can be only one component on a page

future too.

Hi, I am Vishwash Gaur. Today, I am going to present a beginner series webinar on the topic of Component and Module development in Joomla 2.5
There would be an added benefit if you have downloaded, installed and used Joomla! a little bit in prior.In reducing the procedural code issues i.e. lack of code reusability, higher debugging time and more
Modules typically makeup the elements of sidebar or content menus. Module complements the content contained in a component; they are not intended to be main sub-stance of the page.Modules are installed through the admin panel, they don’t manipulate any data from the database all what they do is display the contents on the page like examples on the page.
Module folder is located inside the modules directory of either front end or backend as per the case of development.
Components frequently have sophisticated back-end controls. The back-end is commonly used to create and manage the records from database. In Joomla, Content manager and Banner manager are examples of a component.Convention: Decide structure of component before development i.e. for front end, back end or both – it would allow you easy programming reference during the development.
