Ok, every time we refresh catalog detail page, we will see randonm string. Now, I want the random string to be refreshed when customer add a product to cart. etc/frontend/sections.xml - <?xml version="1.0"?>
- <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
- xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Customer:etc/sections.xsd">
- <action name="checkout/cart/add">
- <section name="customsection"/>
- </action>
- </config>
