Does anybody know of a good tutorial on how to implement form validation in a custom module in the Shopware 6 administration? The “how to’s” that I found go into the details of crud actions, but without any reference to validations. As a newbe to Shopware 6 programming, the existing Shopware 6 administration modules unfortunately are a bridge too far at this point in my learning curve ;-)
This brought me one step closer to implementing form validations in the backend. I do wonder though how to tie the validations into an entity’s API. Take customer as an example:
(BTW it looks like this has changed from my SW6 developer version, which defines e.g. an account service in customer.xml that mentions a validation factory).
A tutorial that describes what I need to define where in this context as per the latest SW6 programming guidelines would really help!
