This MIVA Merchant plugin module inserts the category name directly below the product name in the Basket (BASK) and Invoice (INVC) screens. When a product is in more than one category, the module displays all of them. Each category name is linked to the corresponding category list screen in the Basket Screen.
This module is licensed to one domain. It may be used in more than one store within the same domain without additional licensee fees.
Also, in Merchant version 4.14-4.2x, the module creates a basket price sum variable which can optionally be displayed in the basket and invoice. This price variable combines the product's basket base price with its attribute prices so that you can show the sum total for the product and hide the individual attribute prices in the basket. This is particularly useful when you have products with a base price of $0.00 and the actual price is based on the attributes selected.
While use of the OpenUI is recommended, the module does have tokens that can be used in page templates to run the code to display the categories or price combination.
We also have the corresponding module for the 5.x version of Merchant.
