Details edit

  • &$template: UsercreateTemplate instance for the form

Deprecated edit

From MediaWiki 1.27 on, the hook is deprecated and superseded by AuthManager functionality. Login form fields should be added by some authentication provider returning an instance of an appropriate AuthenticationRequest subclass instance in getAuthenticationRequests(), and that object can define the fields via getFieldInfo(). The authentication provider can read the submitted data from the AuthenticationRequest object via its testForAuthentication or beginPrimaryAuthentication/continueAuthentication methods.

For purely cosmetic changes to the form, which don't need to be reflected to the API (such as adding more information or interactive widgets) the AuthChangeFormFields hook can be used.
