Hello, can you show us how to limit the user to purchase whatever they like from one single category?

I bought this plugin since all of the code I found didn't work: https://stephensherrardplugins.com/plugins/woocommerce-user-role-minimums/
If you are using "/checkout/?add-to-cart=id" (as opposed to /cart...) and having the product added twice, try adding this to your functions.php file:
`add_filter( 'woocommerce_add_to_cart_redirect', 'bbloomer_redirect_checkout_add_cart' );
function bbloomer_redirect_checkout_add_cart() {
return wc_get_checkout_url();
}`
I needed to bypass the cart so this works for me. Good luck!

This doesn't seem to work when I change the quantity to 1. I'm not able to add a product to the cart anymore. And how can I add a 2nd category? I need to have the situation where the customer can select 1 product per category wit max 2 products in the cart.
So if you change the quantity validation from >= to > it will work
// validate if qty not already over if($running_qty > self::ALLOWED_QTY) { self::throwErrorNotice(); return false; }
