Question

How to implement the sale of goods in fractional sq m, if the price of the order is for 1 sq m
.
Or maybe there are other ways to change the price before putting it in the cart. but without changing it for 1 square in the admin panel.

Answer 1

in functions.php

function min_decimal($val) {
    return 0.01; // Минимальное значение
}

add_filter("woocommerce_quantity_input_min", "min_decimal");

function step_decimal($val) {
    return 0.01; // Шаг    
}

add_filter("woocommerce_quantity_input_step", "step_decimal");

// Удаление и добавление своего фильтра проверки количества

remove_filter("woocommerce_stock_amount", "intval");
add_filter("woocommerce_stock_amount", "floatval");
