I wanted to add total price in single product page. Unfortunately I'm not a programmer. It means I actually don't know about JavaScript or code well.
So I searched some codes on google and added it in function.php file.
This is the code:
add_action( 'woocommerce_single_product_summary', 'woocommerce_total_product_price', 29 );
function woocommerce_total_product_price() {
    global $woocommerce, $product;
    echo sprintf('<div id="product_total_price" style="margin-bottom:20px;">%s %s</div>',__('price total','woocommerce'),'<span class="price">'.$product->get_price().'</span>'.'KRW');
    ?>
        <script>
            jQuery(function($){
                var price = <?php echo $product->get_price(); ?>,
                    currency = '<?php echo get_woocommerce_currency_symbol(); ?>';
                $('[name=quantity]').change(function(){
                    if (!(this.value < 1)) {
                        var product_total = parseFloat(price * this.value);
                        $('#product_total_price .price').html(product_total.toFixed(0));
                    }
                });
            });
        </script>
    <?php
}
My problem is the code doesn't show thousands separator. How can I do that?
And I want to add the total price between quantity and add to cart button. Now the total price is before quantity.
Thanks.
