Sonata Admin how to read not mapped field?

forms, php, sonata-admin, symfony

Solution

You can simply get Form and filed data in your admin class. In method postUpdate:

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

Problem

I added fields with the option `"mapped" => false` to a SonataAdmin form. Now I need to access the values of the form fields marked with `"mapped" => false` in the method `postUpdate`. How can I retrieve them?
