After applying a filter, I need to save the url value and automatically show it in a field when a new communication (" Aggiungi comunicazione") is created. Can you help me? Thx

CodePudding user response：

you can get the Referer url on the setupCreateOperation with: request()->headers->get('referer')

PLEASE make sure you properly sanitize any input you get from the url, otherwise it could be a severe security issue.
