Control customer who bought can write review

Question

I want to accept customer who purchases can fill on review form. If a customer doesn't buy it, it'll show a notification that you must buy it before writing review. Can you help me how to work? Thanks.

Answer 1

I can give you a brief idea.

You would need to put condition in the review form.

Put below conditions before code:

• Whether a customer is logged in or not
• If customer is logged in, then check whether customer has ordered the same product SKU or not.

Please let me know if you have any query.

Update: To check whether customer is logged in or not, try below code:

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$customerSession = $objectManager->get('Magento\Customer\Model\Session');
if($customerSession->isLoggedIn()) {
   // customer login action
}
