You can learn how to add a custom amount in order total from here:
http://webkul.com/blog/add-custom-pricefee-order-total-magento2/
Now, if you want to display the custom price fee on the sales order view page, then you can follow the following process:
firstly, you need to create a sales_order_view.xml file in the folder:
app/code/Webkul/Test/view/frontend/layout
<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
<body>
<referenceContainer name="order_totals">
<block class="Webkul\Test\Block\Sales\Order\Test" name="customfee"/>
</referenceContainer>
</body>
</page>
Now, you need to define a block file in which you need to define the init_totals() function, which adds a custom fee amount to your order view.
<?php
namespace Webkul\Test\Block\Sales\Order;
use Magento\Sales\Model\Order;
class Test extends \Magento\Framework\View\Element\Template
{
/**
* @var Order
*/
protected $_order;
/**
* @var \Magento\Framework\DataObject
*/
protected $_source;
/**
* @param \Magento\Framework\View\Element\Template\Context $context
* @param array $data
*/
public function __construct(
\Magento\Framework\View\Element\Template\Context $context,
array $data = []
) {
parent::__construct($context, $data);
}
public function getSource()
{
return $this->_source;
}
public function displayFullSummary()
{
return true;
}
public function initTotals()
{
$parent = $this->getParentBlock();
$this->_order = $parent->getOrder();
$this->_source = $parent->getSource();
$title = 'Custom Fee';
$store = $this->getStore();
if($this->_order->getCustomfee()!=0){
$customAmount = new \Magento\Framework\DataObject(
[
'code' => 'customfee',
'strong' => false,
'value' => $this->_order->getCustomfee(),
'label' => __($title),
]
);
$parent->addTotal($customAmount, 'customfee');
}
return $this;
}
/**
* Get order store object
*
* @return \Magento\Store\Model\Store
*/
public function getStore()
{
return $this->_order->getStore();
}
/**
* @return Order
*/
public function getOrder()
{
return $this->_order;
}
/**
* @return array
*/
public function getLabelProperties()
{
return $this->getParentBlock()->getLabelProperties();
}
/**
* @return array
*/
public function getValueProperties()
{
return $this->getParentBlock()->getValueProperties();
}
}
Here, the init_totals() function adds the custom fee to your order by using the addTotal() method.
$customAmount is an object of dataObject that stores the label, code, and value for a custom fee.
‘customfee’ is the custom amount field name.
After this, your custom fee amount is visible on the customer’s order view page.
