🛒 WooCommerce Variation Upsell Compatibility

Make Variation Swatches and Checkout Upsell Funnel play nicely — RTL & Hebrew included

A WordPress plugin that fixes the compatibility gaps between WooCommerce Variation Swatches and the WooCommerce Checkout Upsell Funnel, so variation products work correctly inside upsell popups — on standard and RTL stores, with dedicated Hebrew RTL handling.

📑 Table of Contents

❗ The Problem

When a store uses variation swatches (radio / button / color / image) and an upsell funnel at checkout, the swatch selection and add-to-cart logic often break inside the upsell popup — customers can't pick a variation or add the product. On RTL stores (notably Hebrew), the layout and click handling break further. This plugin patches both.

✨ Features

Feature Description
🌍 Universal Compatibility Works on both standard (LTR) and RTL stores.
🔭 Dynamic Popup Detection Uses a MutationObserver to catch and fix popups added on the fly.
🎛️ Variation Selection Fix All swatch types — radio, button, color, image — select correctly in upsell popups.
🛒 Add-to-Cart Fix Restores add-to-cart for variation products inside upsells.
🧩 Special Popup Structures Handles unusual radio-based variation swatch markup.
🇮🇱 Hebrew RTL Support Specialized fixes for Hebrew right-to-left WooCommerce stores.

📋 Requirements

  • WordPress 5.0+
  • WooCommerce 4.0+ (tested up to 8.0)
  • PHP 7.0+
  • WooCommerce Variation Swatches (Pro)
  • WooCommerce Checkout Upsell Funnel

🚀 Installation

  1. Upload the variation-upsell-compatibility folder to /wp-content/plugins/.
  2. Activate the plugin from the Plugins menu in WordPress.
  3. Done — there's nothing to configure. The plugin works automatically when both required plugins are active.

⚙️ How It Works

The plugin detects when both Variation Swatches and Checkout Upsell Funnel are active, then injects targeted JavaScript fixes so they cooperate inside upsell popups.

Key components:

  • js/variation-upsell-fix.js — general compatibility fixes for variation upsells on all stores.
  • js/hebrew-rtl-fix.js — specialized fixes for Hebrew RTL stores, covering every swatch type.

🇮🇱 Hebrew / RTL Support

The Hebrew RTL fix provides dedicated handling for:

  • Radio Button Swatches — keeps radio inputs visible and selectable.
  • Button Swatches — fixes selection state and click handling.
  • Color Swatches — restores selection and visual feedback.
  • Image Swatches — maintains selection state and click handling.
  • Select Dropdowns — correctly updates the hidden <select> elements.

Every variation type gets optimized click handling and immediate visual feedback for a smooth RTL checkout experience.

🩺 Troubleshooting

  1. Open your browser console and check for JavaScript errors.
  2. Confirm both required plugins are active and updated to their latest versions.
  3. Verify your theme is WooCommerce-compatible.
