Member Function Documentation

◆ cloneCollection()

ilLPCollectionOfSCOs::cloneCollection	(	$a_target_id,
		$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

$a_target_id
$a_copy_id

Reimplemented from ilLPCollection.
