I am using WordPress and have installed a plugin called 'EAN for WooCommerce' and another use one plugin 'Email Template Customizer' which allows me to customize the order email. I am customizing and creating an email template within HTML now I have a problem how can I view the information inside the EAN CODE in the HTML template. The plugin is in php how can i see its information in html it is like sku code just like sku code we see in order email so in html I want to see that code in the created template how is it possible. I checked the EAN plugin file, used its class, but the box was empty, and I didn't see anything.
