Class: completion_info - X-Ref
Class represents completion information for a course.Does not contain any data, so you can safely construct it multiple times
without causing any problems.
| get_aggregation_methods() X-Ref |
| Return array of aggregation methods return: array |
| __construct($course) X-Ref |
| Constructs with course details. When instantiating a new completion info object you must provide a course object with at least id, and enablecompletion properties. Property cacherev is needed if you check completion of the current user since it is used for cache validation. param: stdClass $course Moodle course object. |
| is_enabled_for_site() X-Ref |
| Determines whether completion is enabled across entire site. return: bool COMPLETION_ENABLED (true) if completion is enabled for the site, |
| is_enabled($cm = null) X-Ref |
| Checks whether completion is enabled in a particular course and possibly activity. param: stdClass|cm_info $cm Course-module object. If not specified, returns the course return: mixed COMPLETION_ENABLED or COMPLETION_DISABLED (==0) in the case of |
| print_help_icon() X-Ref |
| Displays the 'Your progress' help icon, if completion tracking is enabled. Just prints the result of display_help_icon(). |
| display_help_icon() X-Ref |
| Returns the 'Your progress' help icon, if completion tracking is enabled. return: string HTML code for help icon, or blank if not needed |
| get_completion($user_id, $criteriatype) X-Ref |
| Get a course completion for a user param: int $user_id User id param: int $criteriatype Specific criteria type to return return: bool|completion_criteria_completion returns false on fail |
| get_completions($user_id, $criteriatype = null) X-Ref |
| Get all course criteria's completion objects for a user param: int $user_id User id param: int $criteriatype Specific criteria type to return (optional) return: array |
| get_user_completion($user_id, $criteria) X-Ref |
| Get completion object for a user and a criteria param: int $user_id User id param: completion_criteria $criteria Criteria object return: completion_criteria_completion |
| has_criteria() X-Ref |
| Check if course has completion criteria set return: bool Returns true if there are criteria |
| get_criteria($criteriatype = null) X-Ref |
| Get course completion criteria param: int $criteriatype Specific criteria type to return (optional) |
| get_aggregation_method($criteriatype = null) X-Ref |
| Get aggregation method param: int $criteriatype If none supplied, get overall aggregation method (optional) return: int One of COMPLETION_AGGREGATION_ALL or COMPLETION_AGGREGATION_ANY |
| get_incomplete_criteria() X-Ref |
| clear_criteria() X-Ref |
| Clear old course completion criteria |
| is_course_complete($user_id) X-Ref |
| Has the supplied user completed this course param: int $user_id User's id return: boolean |
| user_can_override_completion($user) X-Ref |
| Check whether the supplied user can override the activity completion statuses within the current course. param: stdClass $user The user object. return: bool True if the user can override, false otherwise. |
| update_state($cm, $possibleresult=COMPLETION_UNKNOWN, $userid=0,$override = false, $isbulkupdate = false) X-Ref |
| Updates (if necessary) the completion state of activity $cm for the given user. For manual completion, this function is called when completion is toggled with $possibleresult set to the target state. For automatic completion, this function should be called every time a module does something which might influence a user's completion state. For example, if a forum provides options for marking itself 'completed' once a user makes N posts, this function should be called every time a user makes a new post. [After the post has been saved to the database]. When calling, you do not need to pass in the new completion state. Instead this function carries out completion calculation by checking grades and viewed state itself, and calling the involved module via mod_{modulename}\\completion\\custom_completion::get_overall_completion_state() to check module-specific conditions. param: stdClass|cm_info $cm Course-module param: int $possibleresult Expected completion result. If the event that param: int $userid User ID to be updated. Default 0 = current user param: bool $override Whether manually overriding the existing completion state. param: bool $isbulkupdate If bulk grade update is happening. return: void |
| internal_get_state($cm, $userid, $current) X-Ref |
| Calculates the completion state for an activity and user. Internal function. Not private, so we can unit-test it. param: stdClass|cm_info $cm Activity param: int $userid ID of user param: stdClass $current Previous completion information from database return: mixed |
| get_grade_completion(cm_info $cm, int $userid) X-Ref |
| Fetches the completion state for an activity completion's require grade completion requirement. param: cm_info $cm The course module information. param: int $userid The user ID. return: int The completion state. |
| set_module_viewed($cm, $userid=0) X-Ref |
| Marks a module as viewed. Should be called whenever a module is 'viewed' (it is up to the module how to determine that). Has no effect if viewing is not set as a completion condition. Note that this function must be called before you print the page header because it is possible that the navigation block may depend on it. If you call it after printing the header, it shows a developer debug warning. param: stdClass|cm_info $cm Activity param: int $userid User ID or 0 (default) for current user return: void |
| count_user_data($cm) X-Ref |
| Determines how much completion data exists for an activity. This is used when deciding whether completion information should be 'locked' in the module editing form. param: cm_info $cm Activity return: int The number of users who have completion data stored for this |
| count_course_user_data($user_id = null) X-Ref |
| Determines how much course completion data exists for a course.

| is_course_locked() X-Ref |
| Check if this course's completion criteria should be locked return: boolean |

| reset_all_state($cm) X-Ref |
| Recalculates completion state related to an activity for all users. Intended for use if completion conditions change. (This should be avoided as it may cause some things to become incomplete when they were previously complete, with the effect - for example - of hiding a later activity that was previously available.) Resetting state of manual tickbox has same result as deleting state for it. param: stcClass|cm_info $cm Activity |
| get_data($cm, $wholecourse = false, $userid = 0, $unused = null) X-Ref |
| Obtains completion data for a particular activity and user (from the completion cache if available, or by SQL query) param: stdClass|cm_info $cm Activity; only required field is ->id param: bool $wholecourse If true (default false) then, when necessary to param: int $userid User ID or 0 (default) for current user param: null $unused This parameter has been deprecated since 4.0 and should not be used anymore. return: object Completion data.

| get_progress_all($where = '', $where_params = array() X-Ref |
| Obtains progress information across a course for all users on that course, or for all users in a specific group. Intended for use when displaying progress. This includes only users who, in course context, have one of the roles for which progress is tracked (the gradebookroles admin option) and are enrolled in course. Users are included (in the first array) even if they do not have completion progress for any course-module. param: bool $sortfirstname If true, sort by first name, otherwise sort by param: string $where Where clause sql (optional) param: array $where_params Where clause params (optional) param: int $groupid Group ID or 0 (default)/false for all groups param: int $pagesize Number of users to actually return (optional) param: int $start User to start at if paging (optional) param: context $extracontext If set, includes extra user information fields return: stdClass with ->total and ->start (same as $start) and ->users; |
