✨ Features

  • 🛒 Slide-in AJAX side cart drawer — opens automatically on add-to-cart; stays perfectly in sync through WooCommerce's own fragment system. Floating cart button with live item-count badge.
  • 🚚 Free shipping progress bar — the classic "Add $12 more for free shipping" nudge. Threshold auto-detected from your Free Shipping method, or override it manually / via filter.
  • 🏷 Coupons inside the drawer — customers apply and remove coupon codes without leaving the page. Validation comes from WooCommerce core, so usage limits and expiry rules just work.
  • 🔗 In-cart cross-sells — your product cross-sells rendered inside the drawer with AJAX add-to-cart.
  • ✅ One-click order bump — a discounted offer with strikethrough pricing and a "Save X%" badge above the place-order button. Percentage or fixed-amount discounts.
  • 📊 Bump analytics — offers accepted, orders with bump, bump revenue and checkout conversion, tracked privately in your own database.
  • 🎨 Brandable — left/right drawer position plus an accent color picker that recolors the button, progress bar, coupons and bump box.
  • ♿ Accessible — dialog semantics, keyboard focus trap, Escape to close, prefers-reduced-motion support, aria-live coupon feedback.
  • 🌍 Translation-ready — all strings internationalized, .pot template included.
  • 🧹 Clean — no external HTTP calls, no tracking, no license checks, no build step; HPOS compatible; fully removed on uninstall.

⚙️ Developer API

Small, documented surface — no hook spaghetti:

Hook Type Purpose
wscb_free_shipping_threshold filter Change the free shipping bar threshold at runtime.
wscb_setting filter Override any plugin setting at read time ($value, $key).
wscb_drawer_opened / wscb_drawer_closed JS event (body) React to the drawer opening/closing.
wscb_coupon_updated JS event (body) Fires after a coupon is applied/removed (array of applied codes).
wscb_open_drawer JS event (body) Open the drawer programmatically.
[data-wscb-open] HTML attribute Add to any element to open the drawer on click. 
// Example: open the drawer from your own code.
jQuery( 'body' ).trigger( 'wscb_open_drawer' );
// Example: 150 free-shipping threshold for everyone.
add_filter( 'wscb_free_shipping_threshold', fn () => 150.0 );

AJAX endpoints (?wc-ajax=…): wscb_update_cart_item, wscb_apply_coupon, wscb_remove_coupon, wscb_toggle_bump — all nonce-protected, guests included.

❓ FAQ

Does the order bump work with the block checkout? Not yet — the bump renders on the classic [woocommerce_checkout] shortcode checkout, which most themes and checkout plugins use.

How is the free shipping threshold detected? From your configured Free Shipping methods (min_amount) across all shipping zones, falling back to the legacy setting. Override it in settings or with the wscb_free_shipping_threshold filter.

Where is the bump revenue number from? Bump line items are flagged with hidden order item meta (_wscb_bump); orders containing one count as conversions and their line totals count as revenue. Nothing leaves your server.

Does it create database tables? No. Two options rows (settings + analytics counters), both deleted on uninstall.

See the full FAQ in the docs.
