Creating tailored digital experiences often requires going beyond standard out-of-the-box features. This written course guides you through the process of developing custom modules, custom entities, and complex business logic in Drupal. You will transition from basic site-building to writing clean, maintainable, and secure object-oriented code. By reading through structured explanations and analyzing real-world code snippets, you will master the underlying APIs and architecture that power Drupal's robust ecosystem. What you'll learn: - Understand foundational Drupal architecture, including the service container, dependency injection, and modern PHP standards. - Build custom content and configuration entities to model complex data structures. - Implement granular access control, custom permissions, and security best practices for your modules. - Configure events, event subscribers, and plugins to alter and extend core system behavior. - Optimize application performance using advanced caching APIs, cache tags, and contexts. - Manage configuration deployment workflows using the configuration synchronization system. The course starts with essential terminology and the core concepts of dependency injection before guiding you step-by-step through custom entity creation, routing, the Form API, and advanced event handling. You will learn entirely through clear, written explanations, code examples, and practical conceptual exercises. This course is designed for web developers and Drupal site builders who want to start writing custom code.
