I want to change the price in the Catalog View Page, I use a price attribute with the name rrp, and I need when customers are logged to display this price attribute otherwise display the normal price. I do this in Category Page like this:

                $objectManager = \Magento\Framework\App\ObjectManager::getInstance();
                $customerSession = $objectManager->get('Magento\Customer\Model\Session');
                if($customerSession->isLoggedIn()) {
                    <?= /* @noEscape */ $block->getProductPrice($_product) ?>
                <?php } else { ?>
                    <div class="price-box">
                        <span class="regular-price" id="product-price-<?php $_product->getId() ?>">
                            <span class="price">
                                <?php $pricingHelper = $this->helper(\Magento\Framework\Pricing\Helper\Data::class); ?>
                                <?php echo $pricingHelper->currency($_product->getData('rrp'), true, false); ?>
                <?php } ?>

But how I can do the same for Product View?

Thank you

  • What price should be when product will be added to cart ? Is this for display purpose only ? Commented Feb 27, 2020 at 13:07
  • @AnilSuthar in the cart must be the correct price, for example if the customer is logged then in the Cart will be the rrp price, otherwise the normal price.

You should create a plugin that changes the price after product loaded.

1 > Create di.xml file :

    <type name="Magento\Catalog\Model\Product">
        <plugin name="change_product_price" type="VENDOR_NAME\MODULE_NAME\Plugin\Product" sortOrder="1"/>

2 > Change the product price :



class Product
    public function afterGetPrice(\Magento\Catalog\Model\Product $subject, $result)
        // Create your logic here to change product price and return it
        return $result + 100;

3 > Flush Cache and Test

Your logic should be (Just for demo. Not Tested and don't use ObjectManager directly, use dependency instead.) :

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$customerSession = $objectManager->get('Magento\Customer\Model\Session');
if($customerSession->isLoggedIn()) {
    return $subject->getData('rrp');
    return $result;
