Hello World Plugin for Joomla!

This is a ready to go Joomla Plugin Boilerplate that you can use to build your own plugins. I have added all the settings, elements and things I could find.

What does it do?

This is a content plugin that replaces a user defined shortcode with a language sensitive Hello World statement. You can set the language in the plugin.

How to use this module

• Install the plugin.
• Configure the plugin how you want it, including making sure to publish it.
• Insert the shortcode into an article.
• Load the newly saved article, with the shortcode, and you should see the shortcode has been replaced with the Hello World message..

Notes

• When the install mechanism is used, the title for the plugin comes from en-GB.plg_qwrealurl.sys.ini / PLG_QWREALURL_NAME="Hello World"
• The plugin name is helloworld
  • Can be called by $this->_name
  • Is made from the filename helloworld.php, the .php file extension is removed.
• You can restrict this plugin to work only on certain components using $context.

Compatibility

plg_helloworld is fully compatible with Joomla versions 3.x (possibly only 3.8+) and 4.x. A few alterations and the plugin will work on earlier versions of Joomla.

License

plg_helloworld is a Joomla module developed by QuantumWarp and released under the GNU General Public License.
