How to Add Custom Block to Order View Information in Magento

We will introduce several ways to add a new custom block to order view, code snippets are under a module named Dolphin_OrderSection.

Step 1: Create Registration

Create registration.php file in the app/code/Dolphin/OrderSection folder with the following code.

<?php

use Magento\Framework\Component\ComponentRegistrar;

ComponentRegistrar::register(ComponentRegistrar::MODULE, 'Dolphin_OrderSection', __DIR__);

<?php

use Magento\Framework\Component\ComponentRegistrar;

ComponentRegistrar::register(ComponentRegistrar::MODULE, 'Dolphin_OrderSection', __DIR__);

Step 2: Create a module

Create a module.xml file in the app/code/Dolphin/OrderSection/etc folder with the following code.

<?xml version="1.0" ?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Step:3 Create a Layout

Create a sales_order_view.xml file in the app/code/Dolphin/OrderSection/view/adminhtml/layout folder with the following code.

<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="admin-2columns-left"
      xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
    <body>
        <!--add custom block -->
        <referenceBlock name="order_additional_info">
            <block class="Dolphin\OrderSection\Block\Adminhtml\Order\View\View" name="sales_custom_view"
                   template="Dolphin_OrderSection::order/view/view.phtml"/>
        </referenceBlock>

    </body>
</page>

<?xml version="1.0"?>

<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="admin-2columns-left"

xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">

<body>

<block class="Dolphin\OrderSection\Block\Adminhtml\Order\View\View" name="sales_custom_view"

template="Dolphin_OrderSection::order/view/view.phtml"/>

</referenceBlock>

</body>

</page>

A block is a unit of page output that renders some distinctive content (anything visually tangible for the end-user), such as a piece of information or a user interface element.

- class: A fully-qualified class name, such as Vendor\Module\Block\Class. Defaults to Magento\Framework\View\Element\Template. ex: “Dolphin\OrderSection\Block\Adminhtml\Order\View\View”
- name: 0-9, A-Z, a-z, underscore (_), period (.), dash (-). Should start with a letter. Case-sensitive. ex: “sales_custom_view”
- template:Vendor_Module::path/to/template.phtml (Scope is already in the templates directory of the module) ex: “Dolphin_OrderSection::order/view/view.phtml”

Step:4 Create a Block

Create a View.php file in the app/code/Dolphin/OrderSection/Block/Adminhtml/Order/View folder with the following code.

<?php

namespace Dolphin\OrderSection\Block\Adminhtml\Order\View;
class View extends \Magento\Backend\Block\Template
{
    public function getOrderCustom()
    {

        //your custom code in here
        $returnData = "Dolphin";
        return $returnData;
    }
}

<?php

namespace Dolphin\OrderSection\Block\Adminhtml\Order\View;

class View extends \Magento\Backend\Block\Template

{

public function getOrderCustom()

{

//your custom code in here

$returnData = "Dolphin";

return $returnData;

}

Step:5 Create a Template

Create a template file that will be used to call block function. Create view.phtml file in the app/code/Dolphin/OrderSection/view/adminhtml/templates/order/view with the following code.

<?php
/**
 * @var $block \Dolphin\OrderSection\Block\Adminhtml\Order\View\View
 */
?>
<div class="admin__page-section-item order-custom-information">
    <div class="admin__page-section-item-title">
        <span class="title">Custom Information</span>
    </div>
    <div class="admin__page-section-item-content">
        <div class="order-custom-information-title">Add custom block information</div>
    </div>
</div>

<?php

/**

* @var $block \Dolphin\OrderSection\Block\Adminhtml\Order\View\View

<span class="title">Custom Information</span>

</div>

<div class="order-custom-information-title">Add custom block information</div>

</div>

After that, clear the cache, go to sales order and click to view any order. you will see your custom information block.
