Get the total stock of all variations from a variable product In Woocommerce

Question

IN woocommerce I would like to display the total stock of all variations in a variable product. The stock of each product variation is managed at the product variation level

Answer 1

add_action( 'woocommerce_before_add_to_cart_button', 'get_selected_variation_stock' );
function get_selected_variation_stock() {
    global $product;

    if ($product->is_type( 'variable' ))
    {
        $avail_vari = $product->get_available_variations();
        foreach ($avail_vari as $key => $value)
        {
            $vari_id = $value['variation_id'];
            $vari_colr = $value['attributes']['attribute_pa_colour'];
            $vari_obj = new WC_Product_variation($vari_id);
            $vari_stock = $vari_obj->get_stock_quantity();

            echo $vari_colr . ": " . $vari_stock . " ";

        }
    }

Paste this code into function.php of your theme and hurray your work will be done.
