Forms in Symfony 3

on YouTube ↗49m

" summary

Symfony 3 Form component applied inside a DDD app: a three-layer CRM example (domain, application, infrastructure) with three hands‑on assignments in a 3‑hour workshop. Shows CRUD for Organization using empty_data to instantiate aggregates with nonstandard constructors, explains FormBuilder vs immutable Form instance and handleRequest method, implements DataTransformer for PhoneNumber/Email (including TransformationFailedException and custom invalid messages), resolves block prefix collisions by overriding getBlockPrefix, and uses DataMapper for multi-field Address and ProposedContact command to build commands instead of persisting entities directly.
