Details edit

NOTE: Consider using ParserOptionsRegister instead.

  • &$confstr: Reference to a hash key string which can be modified
  • User $user: User object that is requesting the page
  • &$forOptions: Array of options used to generate the $confstr hash key

A parser extension which depends on user options should install this hook and append its values to the key.
