Joomla Hello World Module

This post documents my experience while following the Creating a simple module Joomla 3.x tutorial. I am brand new to Joomla and wanted to share my experience for anyone else trying to develop, install and demo this module in their Joomla 3 environment.

After following the steps in the tutorial, you can compare your mod_helloworld files to the files I have pushed to github. Additionally, here is the file structure of the module.


  • mod_helloworld
    • sql
      • mysql
        • install.mysql.utf8.sql
        • uninstall.mysql.utf8.sql
    • tmpl
      • default.php
      • index.html
    • helper.php
    • index.html
    • mod_helloworld.php
    • mod_helloworld.xml

Install the Module

I created the module directly in the Joomla modules folder. For example,

Using XAMPP for Windows as my local Joomla development environment.

In this example, install the module as follows:

  1. Copy the mod_helloworld folder into the Joomla modules folder if it isn’t already there.
  2. In the Joomla Administration page (/administrator), navigate to Extensions > Manage
  3. Select Discover from the sub menu.
  4. Select the Discover button.
  5. Check the box next to the Hello World module.
  6. Select the Install button.
