The restriction is bidirectional: if a product from Category A is in the cart, products from Category B cannot be added, and vice versa. ### Features: * Define unlimited category restriction pairs * Fully bidirectional — one rule covers both directions * Supports category hierarchies (subcategories inherit parent restrictions) * Disabled add-to-cart buttons on shop and product pages with a clear explanation * Option to show the explanation (for why a product can’t be added) with a clear message, or a tooltip ## Screenshots [⌊Settings screen⌉⌊Settings screen⌉[ Settings screen [⌊Product can not be added (shop page)⌉⌊Product can not be added (shop page)⌉[ Product can not be added (shop page) [⌊Product can not be added (product page)⌉⌊Product can not be added (product page )⌉[ Product can not be added (product page) ## Installation #### Installation from within WordPress 1.

Sometimes you do not want customers to purchase products from specific different categories at the same time. For example, they can buy something from the TOYS category, and they can buy something from the CLOTHING category, but not at the same time. So once they have a product from the TOYS category in the cart, they can’t add something from the CLOTHING category, or vice versa. This plugin lets you do that and restricts products from certain categories to be in the cart together. ### Why? Maybe products from Category A are shipped from one warehouse, and products from Category B are shipped from another warehouse, and you want every order to contain products from the same warehouse. Or maybe products from Category C have free shipping, and products from Category D require shipping costs and having those products in the same order complicates your shipping. There’s a few situations where this will be useful! ### I want people to be able to order TOYS and APPAREL WOMEN together, but not any -other- subcategories from APPAREL (MEN and KIDS). Don’t create a restriction between TOYS and APPAREL. Instead, you would need to set up 2 restrictions: – TOYS and APPAREL MEN – TOYS and APPAREL KIDS With this setup, TOYS can be purchased together with products from APPAREL WOMEN, but TOYS can not be purchased with products from any other subcategory in APPAREL. ### I need more help please!
