Solved: Re: Using Object Manager to get Order Information

stanhook · ‎09-24-2020

Hi,

I am trying to get some order information for a shipping module to display in the admin. I have this in view/adminhtml/templates/order/view/custom_fields.phtml

$orderId = $this->getRequest()->getParam('order_id');
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$order = $objectManager->create('Magento\Sales\Api\Data\OrderInterface')->load($orderId);

$shippingMethod = $order->getShippingDescription();
$shippingMethod = $order->getShippingmethod();
echo 'Shipping is ' . $order->getShippingMethod();

This gets the information just fine. But I know that I shouldn't use Object Manager this way. I tried something in Block/Order/Info.php and something in my di.xml file but that didn't work. What do I need to do so this works the right way?

Thanks!

Hi @stanhook

You need to create customer controller, block and layout.xml for specific page where you are using this phtml file.
For example:

namespace Vendor\Module\Controller\Category;
class View extends \Vendor\Module

\Controller\Category
{
    /**
     * @var \Magento\Framework\Controller\Result\ForwardFactory
     */
    protected $_coreRegistry = null;
    /**
     * @var \Magento\Framework\View\Result\PageFactory
     */
    protected $resultPageFactory ;

    /**
     * @param \Magento\Backend\App\Action\Context $context
     * @param \Magento\Framework\View\Result\PageFactory $resultPageFactory
     */
    public function __construct(        \Magento\Framework\App\Action\Context $context, 
        \Magento\Framework\View\Result\PageFactory $resultPageFactory,
        \Magento\Framework\Registry $registry

    ) {
        $this->resultPageFactory  = $resultPageFactory;
        $this->_coreRegistry = $registry;
        parent::__construct($context);
    }

    /**
     * Product list page
     *
     * @return \Magento\Backend\Model\View\Result\Page
     */
    public function execute()
    {   
        $resultPage = $this->resultPageFactory ->create();
        $blockInstance = $resultPage->getLayout()->getBlock('category.index');

    }
}

layout in frontend

<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../../../lib/internal/Magento/Framework/View/Layout/etc/page_configuration.xsd"> 
    <body>
        <referenceContainer name="content">
            <block class="Vendor\Module\Block\Faq" name="category.index" template="Addon_Faq::view.phtml"/>               
        </referenceContainer>
    </body>

</page>

your xml name should be controller_modle_view.xml.

and create custom block by name
Vendor\Module\Block\Faq

Where you can create your custom function which can you in phtml file directly.

Hope it may help you!

@stanhook you can create a Block and try the below code

namespace EmizenTech\Module\Block;
use Magento\Catalog\Api\ProductRepositoryInterface;
class Order extends \Magento\Framework\View\Element\Template
{
    protected $order;
	public function __construct(
		\Magento\Sales\Api\Data\OrderInterface $order,
	) 
	{
		$this->order = $order;
    }

	public function getOrder()
	{
			$orderId = $this->getRequest()->getParam('order_id');
			$order = $this->order->load($orderId);
	}
}

inside the phtml file, you can just call below code

$order = $block->getOrder();
$shippingMethod = $order->getShippingDescription();
$shippingMethod = $order->getShippingmethod();
echo 'Shipping is ' . $order->getShippingMethod();

I hope it helps!

Hi @amitsamsukha,

I tried the code as you have it:

use Magento\Catalog\Api\ProductRepositoryInterface;

/**
 * Invoice view  comments form
 *
 * @api
 * @author      Magento Core Team <core@magentocommerce.com>
 * @since 100.0.2
 */
class Info extends \Magento\Framework\View\Element\Template
{
    protected $order;

    public function __construct(
        \Magento\Sales\Api\Data\OrderInterface $order
    ) 
    {
        $this->order = $order;
    }

    /**
     * Retrieve current order model instance
     *
     * @return \Magento\Sales\Model\Order
     */

    public function getOrder()
    {
            $orderId = $this->getRequest()->getParam('order_id');
            $order = $this->order->load($orderId);
    }
}

in my phtml:

$order = $block->getOrder();

echo 'order id ' . $order . '<br />';

$shippingMethod = $order->getShippingmethod();
echo 'Shipping is ' . $shippingMethod;

and received this error:

Uncaught Error: Call to a member function getShippingmethod() on null

I can't even get the order id with

$order = $block->getOrder();
echo 'order id ' . $order . '<br />';

Nothing shows.

Thought's?

@stanhook

kindly check the order is you are using is a parameter not into post &

its it should be entity id, not increment id.

Hi @amitsamsukha,

So I tried it with just entering a number:

$orderId = $this->getRequest()->getParam('268');
$order = $this->order->load($orderId);

and just in case I tried this:

$orderId = $this->getRequest()->getParam(268);
$order = $this->order->load($orderId);

And this

$orderId = '268';
$order = $this->order->load($orderId);

This is in the URL:

sales/order/view/order_id/268/key/

And still nothing happens.

Just to note, that if I do this:

public function getTheInfo()
    {
            $info = 'hello';
            return $info;
    }

and this in my phtml file:

echo 'order is '. $block->getTheInfo();

nothing other the the "order is" text appears, "hello" is not there. So I must be doing something wrong. Just to note, that on this page there is other information that is showing in the admin so I know that page is working and being called. I just can't seem to get anything else to work.

Thanks.
Stan
