What are the different ways to handle form submissions in SilverStripe?

Answer: In SilverStripe, form submissions can be handled in several ways:

1. Form Controller: Create a custom controller that extends `PageController` and use a `Form` object within it to process submissions.

2. ModelAdmin: For managing data, use `ModelAdmin`, which automatically handles form submissions for CRUD operations on data models.

3. Form Validation: Implement validation by defining methods in your form classes or using `RequiredFields` and `ValidationResult`.

4. Built-in Form Actions: Utilize built-in actions like `->setRedirect()` for post-submission redirects or custom actions for specific processing.

5. Ajax Forms: For asynchronous submissions, use AJAX with a custom JSON response for form handling.

6. Email Handling: Integrate an email function within form submission handling to notify or confirm with users.

These methods provide flexibility depending on the specific requirements of your application.
