Why this lesson matters

Understand forms and csrf and apply it in a small Laravel feature. Blade is server-rendered presentation: layouts remove repeated page chrome, components package reusable UI, and form helpers preserve security and validation feedback.

  • In Forms and CSRF, keep this failure controlled: Putting queries or business decisions inside Blade templates couples presentation to data access and makes behavior hard to verify.
  • Forms and CSRF practice target: Build a form page from a layout and reusable component, including CSRF protection and validation-error output.
