Member Function Documentation

cloneCollection()

ilLPCollectionOfSCOs::cloneCollection	(	int	$a_target_id,
		int	$a_copy_id
	)

Scorm items are not copied, they are newly created by reading the manifest.

Therefore, they do not have a mapping. So we need to map them via the import_id/identifierref

Parameters

int	$a_target_id
int	$a_copy_id
