I need to get the collection of orders with the the items ordered by using the customer ID. But I am not getting the items ordered in my collection. Please help.

 $objectManager = MagentoFrameworkAppObjectManager::getInstance();
 $order = $objectManager->create('MagentoSalesModelOrder')->getCollection()->addAttributeToFilter('customer_id', $captinId)->setOrder('entity_id',$direction)->setPageSize($pageSize)->setCurPage($currentPage);
 $orderResult = $order->getData();
return $orderResult;

Try the following way:

$captinId = 2;
$direction = 'ASC';
$pageSize = 20;
$currentPage = 1;
$objectManager = MagentoFrameworkAppObjectManager::getInstance();
$orderItemCollection = $objectManager->create('MagentoSalesModelResourceModelOrderItemCollection')
 ->setOrder('entity_id', $direction)
 ->setPageSize($pageSize)
 ->setCurPage($currentPage);

$orderItemCollection->getSelect()->joinLeft(
 'sales_order',
 'sales_order.entity_id=main_table.order_id',
 ['increment_id']
)->where('sales_order.customer_id=?', $captinId);
$orderResult = $orderItemCollection->getData();

Note: Avoid to use MagentoFrameworkAppObjectManager::getInstance()

Please try the code below.

$objectManager = MagentoFrameworkAppObjectManager::getInstance();
$lastyear = date('Y-m-d', strtotime("-1 year"));
$orderCollection = $objectManager->create('MagentoSalesModelResourceModelOrderCollection');
$orderCollection->addAttributeToFilter('customer_id',123456)
 ->addAttributeToFilter('status','complete')
 ->addAttributeToFilter('created_at', array('gteq' => $lastyear))->load();

echo "<pre>";print_r($orderCollection->getData()); exit;

Then you need to load the order items by order ID.

<?php
$orderid = 2;

$objectManager = MagentoFrameworkAppObjectManager::getInstance();
$order = $objectManager->create('MagentoSalesApiDataOrderInterface')->load($orderid);

//Loop through each item and fetch data
foreach ($order->getAllItems() as $item)

 //fetch whole item information
 print_r($item->getData());

 //Or fetch specific item information
 echo $item->getId();
 echo $item->getProductType();
 echo $item->getQtyOrdered();
 echo $item->getPrice(); 


?>
