原文外掛簡介
U2Code Product Addons lets customers personalize the products they buy — engraving text, gift wrap, image swatches, uploaded artwork, donations — and charges for it right on the product page, with a live totals box that updates as they pick.
Build addon groups once and attach them to your whole catalog, to specific products, categories, tags or brands, or add fields to a single product from its own edit screen. No code, no shortcodes.
Try the live demo — the builder and the storefront, ready to click through.
Field types
Multiple Choice — dropdown, radio buttons, checkboxes, buttons, pills, cards, or image and color swatches (square or circle)
Single Checkbox — gift wrap, express handling, an agreement to accept
Short Text — plain text, number, email, phone or URL, with optional character limits
Long Text — multi-line input for gift messages and instructions
Quantity — a numeric amount priced per unit
Date Picker — delivery and pickup dates, with selectable range limits
File Upload — artwork, photos and documents, with file type and size limits
Customer Defined Price — donations, tips, “pay what you want”
Heading — display-only text to structure long forms
Pricing
Charge a flat fee, a percentage of the product price, per quantity, or per character of what the customer types. Every price shows in a live totals box before add to cart and carries through the cart, checkout, order emails and the admin order screen.
Targeting
Assign addon groups to all products, or target specific products, categories, tags and brands — with exclusions
Show fields only for selected variations of a variable product
Reusable option sets, or import options straight from a product attribute
Design
Four storefront themes — Boxed, Compact, Bold and Soft — previewed live in the settings, or switch styling off entirely and use your theme’s own look. All markup uses plain, prefixed CSS classes that are easy to override.
Fits into your store
Classic and block-based (Store API) cart and checkout
Customers can reopen and edit their choices from the cart; you can edit them on the order from the admin
Uploaded files live in a protected folder, and files never attached to an order are cleaned up automatically
Multi-currency: WOOCS, CURCY, Aelia, WCML, WooPayments and Currency Switcher for WooCommerce
WPML and Polylang, including targeting translated products
Works alongside Tiered Pricing Table — addons stack correctly on tier prices
HPOS compatible
Pro version
The paid version adds features for stores that need more:
Date Range field — a start and end date priced per day, for rentals and hire periods
Dimensions field — width × height priced by area, for made-to-measure blinds, glass, fabric and signage
Users & Roles — show addon groups only to certain roles or specific customers, or hide them from some
Multiple file uploads on a single File Upload field
Selection limits — require a minimum and maximum number of choices on multi-select fields
Conditional logic — show or hide any field based on what the customer picked in another, with unlimited rules

Source code & build
The admin app in assets/admin/ is compiled with webpack. Its human-readable
source ships in this plugin under js-source/. To rebuild it:
cd js-source
npm install
npm run build
The output is written to assets/admin/. Everything else in assets/ is
hand-written and used as-is.
