cart must count only different products, not quantities

Hi there,

Admittedly I’m not 100% sure of the use case here: Why would you like to count 3 quantities as 1?

Perhaps it would help if you created a variable product where each variation is a predetermined Kilogram (e.g. 1 Kg, 2Kg, 5Kg, 10Kg etc.) –> Once the variation has been added to the cart, it’ll show up as 1 x 5Kg product) ??

– if I use variations, I can’t easily keep track of sales statistics:
I will see that I have sold:
10 times the 5kg tomatoes
6 times the 1kg tomatoes

Without variation I will see that I have sold.
56 times the 1kg tomatoes
so I sold 56 kg of tomatoes

– With the variations I should foresee all the possibilities, which could be many, complicating both the product creation process and reducing the user’s UX.
Now the user clicks on + and -, or enters the number of kgs from keyboards

In detail the order is shown to the customer who is buying: 10 quantities of tomatoes.
But in the preview on the cart, which shows the number of products in the cart, I would like to show only the number of different products.
If a customer buys 10 quantities of tomatoes, I would like to show 1 and not 10.

Thanks for your help and interest in the use case

Hi there,

But in the preview on the cart, which shows the number of products in the cart, I would like to show only the number of different products.
If a customer buys 10 quantities of tomatoes, I would like to show 1 and not 10.

If you wanted to just always show quantity of 1 for Cart items, you could use this PHP snippet:

// Always display quantity = 1 for Cart items
add_filter( 'woocommerce_cart_item_quantity', 'my_custom_cart_quantity' );
function my_custom_cart_quantity( $quantity ) {
    $quantity = 1;
    return $quantity;
}

Alternatively, since that quantity would be essentially meaningless since it just displays 1 no matter what is in the cart, you could just hide that column in the Cart table with CSS:

/* Hide quantity column in cart */
.woocommerce-cart .product-quantity {
  display: none !important;
}

Finally, if you would like to add full functionality for managing your products in different units (kg, m, etc), you could check out the Measurement Price Calculator extension available here:

I hope that helps! Have a wonderful day!
