Description

HDWebmobile Product Options & Add-ons lets you add paid customization options to any simple product: a text field for engraving, a dropdown for a size or material upgrade, or a checkbox for gift wrap. Each option can add a flat amount to the price, and shoppers see a live running total as they make their selections — before they even click Add to Cart.

Every price is a flat amount you enter yourself and it's looked up fresh from the product whenever something is added to the cart — there is no formula language, expression evaluator, or anything resembling eval() anywhere in this plugin. That's a deliberate design choice: a well-known paid "product add-ons" plugin for WooCommerce disclosed a critical, unauthenticated Remote Code Execution vulnerability caused by unsafely evaluating merchant-defined pricing formulas. This plugin gets the same practical result (customers pay more for the options they pick) without that entire class of risk.

Features

Text, dropdown, and checkbox product options, each with an optional flat price adjustment
A live price preview updates on the product page as customers fill in options, before adding to cart
Works correctly everywhere in WooCommerce: the product page, cart, Mini-Cart, Checkout (classic and block-based), the order confirmation page, order emails, and the admin Edit Order screen -- all using WooCommerce's own standard cart/order mechanisms, not a separate parallel system
Required options are enforced on the server, not just with a browser-side required attribute -- a request that skips a required option is rejected before it reaches the cart
Every submitted option value is re-validated against the product's own current configuration before any price is applied, so a tampered request can't fabricate a discount or a fake option
No formula evaluation of any kind -- every price is a flat, merchant-entered amount
