Hi there Associates!!

In immediately’s weblog, I’ll clarify how we will modify the entire on the checkout web page.

This weblog is helpful if it’s essential to replace the entire primarily based on any situation solely on the checkout web page.

To start with, we are going to create a gross sales.xml file contained in the, and so on folder. You possibly can merely use the under code in your gross sales.xml file.

<?xml model="1.0" ?>

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Sales:and so on/gross sales.xsd">
    <part title="quote">
        <group title="totals">
            <merchandise title="totalupdate" occasion="WebkulTestModelTotalUpdateTotal" sort_order="225"/>
        </group>
    </part>
</config>

Now we are going to create a UpdateTotal.php file contained in the mannequin folder.

You possibly can merely use the under code in your UpdateTotal.php file and modify it accordingly.

namespace WebkulTestModelTotal;

class UpdateTotal extends MagentoQuoteModelQuoteAddressTotalAbstractTotal
{

protected $quoteValidator = null;

    public perform __construct(
    MagentoQuoteModelQuoteValidator $quoteValidator)
    {
    $this->quoteValidator = $quoteValidator; 
    }

    public perform acquire(
    MagentoQuoteModelQuote $quote,
    MagentoQuoteApiDataShippingAssignmentInterface $shippingAssignment,
    MagentoQuoteModelQuoteAddressTotal $complete
    ){
        mum or dad::acquire($quote, $shippingAssignment, $complete);
        
        if (You possibly can outline you situation right here) {
            $extraCharge = 10; // you should use your worth
            $total->setGrandTotal($total->getGrandTotal()+$extraCharge);
            $total->setBaseGrandTotal($total->getBaseGrandTotal()+$extraCharge);
        }else{
            $total->setGrandTotal($total->getGrandTotal());
            $total->setBaseGrandTotal($total->getBaseGrandTotal());  
        }
        return $this;
        
    }

    protected perform clearValues(AddressTotal $complete)
    {
        $total->setTotalAmount('subtotal', 0);
        $total->setBaseTotalAmount('subtotal', 0);
        $total->setTotalAmount('tax', 0);
        $total->setBaseTotalAmount('tax', 0);
        $total->setTotalAmount('discount_tax_compensation', 0);
        $total->setBaseTotalAmount('discount_tax_compensation', 0);
        $total->setTotalAmount('shipping_discount_tax_compensation', 0);
        $total->setBaseTotalAmount('shipping_discount_tax_compensation', 0);
        $total->setSubtotalInclTax(0);
        $total->setBaseSubtotalInclTax(0);
    }
    
}

Now the Complete shall be up to date primarily based in your situation.
