原文外掛簡介
No bloat, no upsells, no page builder — just optional add-ons that follow your product through checkout.
Product Add-Ons lets a store admin attach optional extras to any simple or variable product — for example an Office Chair at $200 with an Extended Warranty (+$30), a Headrest (+$45), a Footrest (+$25) and Premium Assembly (+$50). Shoppers tick the add-ons they want on the product page; the total updates instantly with no page reload, and the selected add-ons and their prices ride along with that product through the cart, checkout, the resulting order, order emails and any invoice built from standard WooCommerce order data.
This plugin is intentionally simple: no page builder, no complex conditional logic, no separate add-on inventory. Just add-ons, priced, optionally imaged, shown in one of five ready-made designs.
Features
Up to 5 add-ons per product, managed from a repeater on the product’s own “Add-Ons” tab
Drag-and-drop reordering, per-add-on enable/disable, name/description/price/image fields
Global default position and design, with an optional per-product override
Five frontend designs: Classic List, Grid Cards, Compact List, Toggle Switches, and Image Cards
Live price preview (Product Price / Add-Ons / Total) with zero page reloads
Add-on price is only ever added when selected — the product’s own base price is never modified
Selections are re-validated and re-priced on the server at Add to Cart — the browser is never trusted for the actual charge
Different add-on selections never merge into the same cart line
Add-ons appear on the cart and checkout review tables, and are saved to the order as line item meta — visible in wp-admin (classic and HPOS), order emails, the customer’s account order view, and most invoice/PDF plugins that read standard order item meta
Works with WooCommerce’s High-Performance Order Storage (HPOS)
Graceful when WooCommerce is inactive — the plugin stays dormant instead of causing a fatal error
Optional data cleanup on uninstall (off by default — your data is safe unless you opt in)
Known limitations (by design, to keep this simple)
The Cart/Checkout blocks (as opposed to the classic shortcode-based Cart/Checkout pages) are not yet officially declared compatible; the underlying data hooks used here are widely supported by WooCommerce Blocks’ backward-compatibility layer, but this hasn’t been exhaustively tested against every block-based theme.
Add-ons are configured per simple/variable product (variable add-ons apply to the whole product, not per-variation).
Add-ons don’t carry their own separate stock/inventory tracking.
The Product CSV importer/exporter and the REST API do not currently include add-on fields.
“Order Again” (re-ordering a past order from My Account) re-adds the base product but does not currently re-select its add-ons.
