Sonata admin, how to read non-displayed field?

Question

I added fields with the option "mapped" => false to the SonataAdmin form.

Now I need to access the values ​​of the form fields marked "mapped" => false in the postUpdate method. How can I get them?

Answer 1

You can simply get the form and data in your admin class. In the postUpdate method:

 $fieldData = $this->getForm()->get('name_of_field')->getData();
