Cloning Elements

Use Service::cloneMe() to get an in-memory copy of any element (anything implementing ElementInterface):

$new = Pimcore\Model\Element\Service::cloneMe($source);

This does not update internal references. For example, a relation in the source element pointing to itself still references the source element in the copy.

For a persistent copy, use the copyAsChild method of the corresponding service:

$user = \Pimcore\Model\User::getById(123);

$assetService = new \Pimcore\Model\Asset\Service($user);
$assetService->copyAsChild($target, $source);

$documentService = new \Pimcore\Model\Document\Service($user);
$documentService->copyAsChild($target, $source); // additional arguments are available for inheritance, ...

$objectService = new \Pimcore\Model\DataObject\Service($user);
$objectService->copyAsChild($target, $source);

Where $source is the source element and $target the parent element of the new element. This also creates a unique element key (or filename for asset elements).

To update references in the copy, call the service's rewriteIds method with a mapper config:

$rewriteConfig = array(
    "object" => array(
        176 => 190
    )
);
$object = DataObject\Service::rewriteIds($object, $rewriteConfig);

This replaces all references to object ID 176 with references to object ID 190 in the copy.
