How To Create Custom Form

How To Create Custom Form

Description

In this episode, you’ll learn how to create a custom form in Sylius. While Sylius generates basic forms automatically, more complex use cases – like dropdowns with predefined values – require custom form types.

Using the “Brand” entity as an example, you’ll learn:

  • How to add a new field (e.g., type) to a resource,
     
  • How to define a select list using class constants,
     
  • How to create a custom form type by extending AbstractResourceType,
     
  • How to register the form as a service and configure it in Sylius,
     
  • How to connect it to the admin interface and test it in action.
     

This episode shows how to combine Symfony flexibility with the powerful Sylius resource system to build advanced and user-friendly admin forms.
