Transform your WooCommerce store with helpful cart validation rules
What is Missing From Cart?
Missing From Cart is a powerful WooCommerce plugin that helps store owners guide customers toward complete purchases by ensuring they add the right combination of products to their cart.
Live demo: Try it yourself
This demo clothing store showcases two validation rules in action:
Rule 1: Complete outfit bundle
To checkout with clothing items, your cart must include:
- Accessories (Hat, Socks, or Shoes)
- Jackets
- Shirts
Try this: Add only a shirt to your cart, then visit the cart page to see the validation message.
Rule 2: Free gift requirement
Every order must include a “Free Gift” item to proceed to checkout.
How to test the demo
- Visit the Shop and browse our products
- Add a shirt to your cart (but skip the other categories)
- Go to your cart – you’ll see a helpful message explaining what’s missing
- Add the missing items and watch the validation clear
- Try checkout to see how smoothly it works
