Powering hundreds of thousands of learning environments globally, Modular Object-Oriented Dynamic Learning Environment, aka Moodle, is used by institutions and organisations large and small across both academic and enterprise spheres making it arguably the world’s most widely used learning platform.

Because it is open-source, Moodle can be customised in any way and tailored to individual needs. Its modular setup and interoperable design allow developers to create PHP plugins and integrate external applications to achieve specific functionalities. Knowledgable Moodle developers are in demand the world over and based on the latest Long Term Support version of Moodle, this book aims to give non-Moodle PHP developers a comprehensive introduction to developing plugins for the platform.

By the end of this book, you will be able to create Moodle plugins to perform just about any task you need to.

The book covers:

  • A short history of Moodle and a high level discussion of the learning environments;
  • Essential information for developing plugins including coding guidelines and development tools;
  • High level descriptions of the common APIs;
  • Exploring common plugin requirements;
  • Developing 10 different common plugins as examples;
  • Other development concepts – backup, git, testing and releasing code to the Moodle plugins directory.

Chapter 1: Introduction to Moodle and Learning Environments: A general overview of the history of Moodle and other learning applications and the current operating environment.
