inherited

Using this object's id field, fetches the matching record in the DB, and looks at each variable in turn.

If the DB has different data, the db's data is used to update the object. This is different from the update() function, which acts on the DB record based on the object.

Return values

bool	True for success, false otherwise.

Member Data Documentation

$optional_fields

array data_object::$optional_fields = array()

inherited

Array of optional fields with default values - usually long text information that is not always needed.

If you want to create an instance without optional fields use: new data_object($only_required_fields, false);

$required_fields

array completion_criteria::$required_fields = array('id', 'course', 'criteriatype', 'module', 'moduleinstance', 'courseinstance', 'enrolperiod', 'timeend', 'gradepass', 'role')

Array of required table fields, must start with 'id'.

Defaults to id, course, criteriatype, module, moduleinstane, courseinstance, enrolperiod, timeend, gradepass, role
