◆ _writeReturned()

ilExerciseMembers::_writeReturned	(	$a_obj_id,

Write returned status.

The returned status is initially 0. If the first file is returned by a user for any assignment of the exercise, the returned status is set to 1 and it will stay that way, even if this file is deleted again. -> learning progress uses this to determine "in progress" status

Parameters

int	exercise id
int	user id
text	status
