In Magento 2, You can redirect to the previous page. This allows customers to redirect back to the page from where the customer came.
In Your Controller write the following code:
<?php namespace Company\Module\Controller\Index; use Magento\Framework\Controller\ResultFactory; class Actionname name extends \Magento\Framework\App\Action\Action { public function execute() { $resultRedirect = $this->resultFactory->create(ResultFactory::TYPE_REDIRECT); //your code work around here $resultRedirect->setUrl($this->_redirect->getRefererUrl()); return $resultRedirect; } }
