Creating a content plugin

An interesting use case of content plugins is using them to include content from other components inside Joomla! articles or even in modules. This gives the administrator of a Joomla! site lots of flexibility and is easy to implement from a developer’s point of view. So, we are going to develop a content plugin that allows the website manager to include these projects in their content.

It’s customary that this kind of plugin uses a shortcode to indicate the project we want to include, so our plugin will use the shortcode {projectlink 42} to embed a link to the project with ID 42 in a Joomla! article:

1. Let’s write our manifest file for this plugin:

   <?xml version="1.0" encoding="UTF-8"?>
   <extension type="plugin" group="content"
     method="upgrade">
       <name>plg_content_projectlink</name>
