    Preserve registration 'extra' values during approval (bug #1001064)

    When approving registration, there is an option to add institution
    staff permission - this property is saved in the 'extra' column of the
    usr_registration table. But if the local registraion submit hook has
    been used to store other properties in this column, they are removed
    during approval. This change ensures the existing properties are left
    in place.

    Don't write logged out user preferences to the db (bug #1001064)

    $USER->set_account_preferences() always saves preferences to the
    usr_account_preference table as well as to $USER. Adding a test for
    the user's id means that this function can be safely called on a
    logged-out user.

    Add local hooks for registration and user initialisation (bug #1001064)

    Three new hooks are added:

    local_init_user() - called after $USER is initialised. This is useful
    for changing the user's theme before $THEME is initialised.

    local_register_submit() - called when the registration form is
    successfully submitted, but before the submitted values are saved to
    usr_registration. This is useful for remembering the properties or
    preferences of the logged-out user when the form was submitted.

    local_post_register() - called after a user has successfully been
    created and logged in during registration. This is useful when
    properties of the user (which may have been saved to usr_registration
    by local_register_submit()) need to be transferred to the newly
    registered user.

Kristina, this isn't a feature that users will notice, it's just an aid to developers who wish to extend or customise Mahara, so I'm not sure it should have the newfeature tag.

Hi Richard,

I think it's a new feature, but it is one that I'll not document in the manual then.
