Code sample

The following code copies an existing object and gives it one location in the node tree. It was taken from the copy view of the content module (kernel/content/copy.php).

The used variables are:

• $object: instance of eZContentObject you want to copy
• $newParentNodeID: node id of the parent for the new object
• $allVersions: true if you want to copy all versions of the object to the new object, false if you only want to copy the currently published version

$db = eZDB::instance();
$db->begin();
$newObject = $object->copy( $allVersions );

$curVersion        = $newObject->attribute( 'current_version' );
$curVersionObject  = $newObject->attribute( 'current' );
$newObjAssignments = $curVersionObject->attribute( 'node_assignments' );
unset( $curVersionObject );

// remove old node assignments
foreach( $newObjAssignments as $assignment )
{
    $assignment->purge();
}

// and create a new one
$nodeAssignment = eZNodeAssignment::create( array(
                                                 'contentobject_id' => $newObject->attribute( 'id' ),
                                                 'contentobject_version' => $curVersion,
                                                 'parent_node' => $newParentNodeID,
                                                 'is_main' => 1
                                                 ) );
$nodeAssignment->store();

// publish the newly created object
include_once( 'lib/ezutils/classes/ezoperationhandler.php' );
eZOperationHandler::execute( 'content', 'publish', array( 'object_id' => $newObject->attribute( 'id' ),
                                                          'version'   => $curVersion ) );
// Update "is_invisible" attribute for the newly created node.
$newNode = $newObject->attribute( 'main_node' );
eZContentObjectTreeNode::updateNodeVisibility( $newNode, $newParentNode );

$db->commit();
