drupal-form-alter

What problem does it solve?

Modifying Drupal forms can require invasive changes; this skill provides a structured pattern to apply hook_form_alter and hook_form_FORM_ID_alter to adjust fields, access controls, and submission handling in a safe, repeatable way.

Core Features & Use Cases

• Combines OOP hooks and procedural hooks for Drupal 10.3+/11 to apply form alterations.
• Common alterations include hiding fields, changing required/default values, and attaching validators or submit handlers.
• Get the Form Object from FormState to access and modify the underlying entity during the alteration process.

Quick Start

Create a MyModuleHooks class and implement formAlter to modify a specific form (e.g., node_article_form) by adding a custom validate handler and a submit handler.
