8.2 WordPress Plugin Structure
Custom plugins follow an organizational pattern compatible with PSR4 rules, with additional consideration for plugin-specific requirements like activation hooks and uninstall procedures. Plugin architecture focuses on modularity and proper WordPress integration. Each major feature area has its own namespace and class structure, making it easy to maintain and extend functionality over time.
