FAQPage Schema

How do I write a Drupal 11 hook_form_alter using OOP instead of procedural code?▼

Drupal 11 OOP hooks use the #[Hook] attribute and are auto-registered in the src/Hook directory. This modern pattern replaces procedural hook_form_alter implementations while maintaining the same alteration capabilities for your module development.

When should I use Drupal hooks versus event subscribers in module development?▼

Drupal hooks are suitable for form alterations and node presave operations, while event subscribers are preferred for decoupled logic. This skill provides decision guidance to choose between procedural hooks and OOP events based on your specific use case.

Does Drupal 11 still support procedural hooks in .module files?▼

Yes, Drupal 11 continues to support classic procedural hooks like hook_form_alter in .module files. You can use procedural implementations alongside modern OOP hooks depending on your module's architectural needs.

What is the correct namespace placement for OOP hooks in Drupal 11?▼

OOP hooks in Drupal 11 must be placed in the src/Hook directory with proper namespace structure. This ensures auto-registration works correctly with the #[Hook] attribute and dependency injection patterns.

Can I use dependency injection with Drupal 11 hooks?▼

Yes, Drupal 11 OOP hooks support dependency injection through the modern auto-registration system. This allows you to inject services directly into your hook classes rather than using procedural service calls.

Why use OOP hooks over procedural hooks in Drupal 11?▼

OOP hooks offer better testability, dependency injection support, and cleaner code organization through auto-registration. Procedural hooks remain viable for simple alterations, but OOP provides modern patterns for complex module development.
