loncreateuser.pm
- include $permission as 3rd arg in calls to lonuserutils::print_upload_manager_form()
and lonuserutils::upfile_drop_add().
- set $env{'form.phase'} to '', so "Create new user" textbox re-displays via breadcrumb link, if username entered in "Create new user" textbox contained prohibited characters.
- include $permission as 7th arg in calls to &print_user_modification_page().
- Add $context (course, author, or domain) as first arg in &user_search_result().
- Additional breadcrumb link for "Results" after completing bulkaction of listed users
- Wording change for links on CUSR main menu (Manage -> Modify for single users).
- &build_search_response() takes $context (course, author, or domain) as first arg
- check whether user can create new accounts if search found no match. Either display creation instructions or message with link to helpdesk if creation prohibited.
- generation of interface for activating a role for a single user moved to &course_level_row() for both standard and custom roles.
- users with section-specific 'cst' priv (e.g., in a custom-role) can create student roles in user's section.
lonuserutils.pm
- $permission arg for print_upload_manager_form() and upfile_drop_add().
- section box in pop-up window generated to allow selection of ne section when
making bulk change to users selected from filtered list generated by §ion_picker().
