I am creating functionality for additional donation. I am trying to add donation amount in quote total but it will not reflect.
This my code portion of that part :
<?php
namespace Yogesh\Donation\Controller\Index;
class Index extends \Yogesh\Donation\Controller\Index
{
public function execute()
{
$post = $this->getRequest()->getPostValue();
$quote = $this->checkoutSession->getQuote();
$donation = $post['donation_amount'];
$grand_total = $quote->getGrandTotal();
$new_grand_total = $grand_total + $donation;
$quote->setGrandTotal($new_grand_total);
$quote->save();
$this->_redirect('checkout/cart');
}
}
?>
Addition of donation amount not display or reflect on front side. How can I update quote total ? Please any one have idea about that.
Thanks
