Why this lesson matters

Understand layouts and components 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.

How to reason about it

  • For Layouts and Components, the outcome to verify is: CSRF protection and repopulating old input are part of a reliable form flow.
  • In Layouts and Components, keep this failure controlled: Putting queries or business decisions inside Blade templates couples presentation to data access and makes behavior hard to verify.
  • Layouts and Components practice target: Build a form page from a layout and reusable component, including CSRF protection and validation-error output.

Practical walkthrough

In the Layouts and Components walkthrough: CSRF protection and repopulating old input are part of a reliable form flow.

    <button type="submit">Save</button>
</form>
