🔧 Issues Fixed

Issue #1: Variation Price Not Updating ✅

Problem:

// WRONG - Using sale_price check
const isOnSale = selectedVariation 
  ? parseFloat(selectedVariation.sale_price || '0') > 0 
  : product.on_sale;

Root Cause:

• Logic was checking if sale_price exists, not comparing prices
• Didn't account for variations where regular_price > price but no explicit sale_price field

Solution:

// CORRECT - Compare regular_price vs price
const currentPrice = selectedVariation?.price || product.price;
const regularPrice = selectedVariation?.regular_price || product.regular_price;
const isOnSale = regularPrice && currentPrice && parseFloat(currentPrice) < parseFloat(regularPrice);

Result:

• ✅ Price updates correctly when variation selected
• ✅ Sale badge shows when variation price < regular price
• ✅ Discount percentage calculates accurately
• ✅ Works for both simple and variable products

Issue #2: Variation Images Not in Gallery ✅

Problem:

// WRONG - Only showing product.images
{product.images && product.images.length > 1 && (
  <div>
    {product.images.map((img, index) => (
      <img src={img} />
    ))}
  </div>
)}

Root Cause:

• Gallery only included product.images array
• Variation images exist in product.variations[].image
• When user selected variation, image would switch but wasn't clickable in gallery
• Thumbnails didn't show variation images

Solution:

// Build complete image gallery including variation images
const allImages = React.useMemo(() => {
  const images = [...(product.images || [])];
  
  // Add variation images if they don't exist in main gallery
  if (product.type === 'variable' && product.variations) {
    (product.variations as any[]).forEach(variation => {
      if (variation.image && !images.includes(variation.image)) {
        images.push(variation.image);
      }
    });
  }
  
  return images;
}, [product]);

// Use allImages everywhere
{allImages && allImages.length > 1 && (
  <div>
    {allImages.map((img, index) => (
      <img src={img} />
    ))}
  </div>
)}

Result:

• ✅ All variation images appear in gallery
• ✅ Users can click thumbnails to see variation images
• ✅ Dots navigation shows all images (mobile)
• ✅ Thumbnail slider shows all images (desktop)
• ✅ No duplicate images (checked with !images.includes())
• ✅ Performance optimized with useMemo

💡 Key Learnings

Price Calculation:

• Always compare regular_price vs price, not check for sale_price field
• WooCommerce may not set sale_price explicitly
• Variation prices override product prices

Image Gallery:

• Variation images are separate from product images
• Must merge arrays to show complete gallery
• Use useMemo to avoid recalculation on every render
• Check for duplicates when merging

Variation Handling:

• Auto-select improves UX significantly
• Attribute matching needs to be flexible (multiple formats)
• Always update price AND image when variation changes
