when I have a create-form of a custom module I would like to add some fields into the html that do not actually belong to this module but another one.
Its only like 2 or 3 fields I would have to add, it would be easy for the user if he could enter all values in a single form. I would like to retrieve the website content in an after save hook and then manually write new records of the other module to db. This requires that during hook execution it is somehow possible to retrieve the original website content to extract the information I need. Is this somehow doable?
