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_”
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
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
http://yoursite.com/index.php?tp=1 Open your page with “?tp=1” at the end of url and it will reveal all Module positions
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.
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
Depends on template Added in template using below code: ◦ <jdoc:include type="component" /> Can be only one component on a page
