    Hello !
    I would like to put decimals in my woocommerce product quantities. I have a php code but there are some bug.
    I would like quantities ranging from 0.10 -> 0.20 -> 0.30> 0.40 ….. it is a textile shop and I sell fabric 10 cm by 10 cm.
    The code causes errors: example: it writes quantities like 0.1000 or it goes from 0.1 to 0.1856 for example
    Are there other solutions? Can you help me?

    here is the php code in function.php :

    // Add min value to the quantity field (default = 1)
    add_filter('woocommerce_quantity_input_min', 'min_decimal');
    function min_decimal($val) {
        return 0.1;
    }
     
    // Add step value to the quantity field (default = 1)
    add_filter('woocommerce_quantity_input_step', 'nsk_allow_decimal');
    function nsk_allow_decimal($val) {
        return 0.1;
    }
     
    // Removes the WooCommerce filter, that is validating the quantity to be an int
    remove_filter('woocommerce_stock_amount', 'intval');
     
    // Add a filter, that validates the quantity to be a float
    add_filter('woocommerce_stock_amount', 'floatval');
     
    // Add unit price fix when showing the unit price on processed orders
    add_filter('woocommerce_order_amount_item_total', 'unit_price_fix', 10, 5);
    function unit_price_fix($price, $order, $item, $inc_tax = false, $round = true) {
        $qty = (!empty($item['qty']) && $item['qty'] != 0) ? $item['qty'] : 1;
        if($inc_tax) {
            $price = ($item['line_total'] + $item['line_tax']) / $qty;
        } else {
            $price = $item['line_total'] / $qty;
        }
        $price = $round ? round( $price, 2 ) : $price;
        return $price;
    }

    Hi there,

    That code looks like it should work. Does it work if you turn off the quantity buttons in Customize > Layout > WooCommerce?

    Hello
    excuse me for my translation, I’m french

    Thank you very much, yes it works! no more bug.

    Can we assign this function.php to a product category?
    Finally can we give a minimum quantity?

    thank you so much

    Hi there,

    Not too sure what you mean – do you only want to apply your functions above to a specific product category?

    You’ve set the minimum quantity in the min_decimal() function.

    thank you for the solution, it’s OK ->”That code looks like it should work. Does it work if you turn off the quantity buttons in Customize > Layout > WooCommerce?”

    I would like to have decimals just for only product category. it’s possible?

    thank you so much

    Hmm, I’m not sure if that’s do-able, as the quantity can be changed in multiple places (including the cart). You might need to check with WooCommerce whether it’s possible.

    If there’s a conditional we can use (is_product_category()) that will work everywhere (the cart too), then I should be able to help.

    OK, thanks
    my knowledge of php is limited
    where should I put this condition?
    thank you

    I’m not sure that condition will actually work for what you’re trying to do. That’s why I mentioned you might want to contact WooCommerce support to see if they have any better ideas.
