Feature: A validator flag that locks the frontend editor only 

Description 

The readonly and disabled flags of a field in Configuration/AcademicPersons/Settings.yaml lock it in the editing frontend and in the TYPO3 backend record editor at the same time. Installations that synchronize a field from a directory service usually want profile owners kept away from it while backend editors can still correct it, and had to reset the backend lock field by field through TCEFORM.

The new flag frontendreadonly locks a field in the editing frontend only. The example keeps the name fields away from profile owners and lets backend editors correct them:

validations:
  profile:
    firstName:
      - required
      - frontendreadonly
    middleName:
      - frontendreadonly
    lastName:
      - required
      - frontendreadonly
  # contract, emailAddress, phoneNumber, physicalAddress and
  # profileInformation repeated as shipped

A validations map of a site package replaces the shipped one as a whole, so every shipped set that should stay has to be repeated. A field that is listed gets exactly the flags listed for it: without required , the backend no longer requires it either.

• The editing frontend shows the field read-only and ignores a submitted value, exactly as for readonly .
• The backend record editor keeps the field editable. A required beside it still makes the field required there, while the editing frontend does not ask the owner for a value they cannot change.
• Listed together with readonly or disabled , the field stays locked in the backend as well.

The flag is matched case-insensitively, like every other flag, and works in every validation set.

Impact 

Nothing changes for an installation that does not list the flag. A TCEFORM reset of readOnly that only served to unlock the backend can be replaced by frontendreadonly in place of readonly .

The settings are cached. Flush the TYPO3 caches after changing Settings.yaml.

Affected Installations 

Installations that lock fields of the profile editing frontend of fgtclb/academic-persons-edit through their own Configuration/AcademicPersons/Settings.yaml.
