SF2C18 | Mastering Symfony Forms

  • In one day, learn the basics and advanced techniques of handling web forms with the Symfony Form component. You will learn how to create simple form types, extend built-in form types, implement data transformers to normalize data, listen to form events to modify data and form structure, and also create form type extensions to dynamically extend multiple form types in one go.

  • Prerequisites

    Basic knowledge of Symfony

  • Goals

    This one-day workshop helps you to get started with the Symfony Form framework. The first part of the workshop is dedicated to (re)discover the basic concepts such as building form types, dealing with options, processing, validating and rendering forms. The second half of the workshop will then tackle more advanced subjects such as form internals, form data transformers, event listeners and even form type extensions.
