Symfony Forms in Detail
summary
Covers the Symfony Form Component internals and concrete how‑tos: wiring DTOs to HTML using form types and DataMapperInterface, instantiating immutable value objects via an empty_data closure, converting SKU/value objects with a model transformer that throws TransformationFailedException, and using Doctrine’s entity type for category choices. Walks through building contact, category and product forms, adding Bootstrap 4 theming, catching domain exceptions and turning them into form errors, and shipping runnable exercises with PHPUnit functional tests and repository branches.
