    Set Custom Price of Product

    First create events.xml file in folder ‘Webkul/Hello/etc/frontend’ and use event ‘checkout_cart_product_add_after’.

    <?xml version="1.0"?>
    <config xmlns:xsi="" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">

    		public function execute(\Magento\Framework\Event\Observer $observer) {
    			$item = $observer->getEvent()->getData('quote_item');

    Is there a way to update selected **bundle product** option price programmatically on cart page?

    by using this code I am able to get Selected Bundle Product Options but I don’t know how to update price for each option Individually?

    $options = $item->getProduct()->getTypeInstance(true)->getOrderOptions($item->getProduct());

    Basically, I want to update quote of single and bundle product with custom price.

    After adding custom price to product currency is not converting on cart page. Please suggest any solution if you also faced the issue.
    Magento ver. 2.1.7

      Hello Ashish,

      You need to convert amount according to currency.
      you can use this snippet to get price according to currency.
      $objectManager = MagentoFrameworkAppObjectManager::getInstance();$storeManager = $objectManager->get(‘MagentoStoreModelStoreManagerInterface’);$priceCurrency = $objectManager->get(‘MagentoFrameworkPricingPriceCurrencyInterface’);$currency = null;$price = 100;$store = $storeManager->getStore()->getStoreId();$price = $priceCurrency->convert($price, $store, $currency);

      if you have any issue or doubt let me know.
