Custom购买现在的按钮不重新定向到WooCommerce中的结帐页面

Question

i我在单个产品页面上放置了一个自定义代码，以便在单个产品页面上使用add按钮，以便在任何产品上快速购买。但这不是重定向到结帐页面，像默认的woocommerce这样的反应 我在ocean themep functions.php文件中使用的代码是：

function sbw_wc_add_buy_now_button_single()
{
    global $product;
    printf('<button id="sbw_wc-adding-button" type="submit" name="sbw-wc-buy-now" value="%d" class="single_add_to_cart_button buy_now_button button alt">%s</button>', $product->get_ID(), esc_html__('Buy Now', 'sbw-wc'));
}
add_action('woocommerce_after_add_to_cart_button', 'sbw_wc_add_buy_now_button_single');

// Handle for click on buy now
function sbw_wc_handle_buy_now()
{
    if (!isset($_REQUEST['sbw-wc-buy-now'])) {
        return false;
    }
    WC()->cart->empty_cart();
    
    $product_id = absint($_REQUEST['sbw-wc-buy-now']);
    $quantity = absint($_REQUEST['quantity']);

    if (isset($_REQUEST['variation_id'])) {
        $variation_id = absint($_REQUEST['variation_id']);
        WC()->cart->add_to_cart($product_id, 1, $variation_id);
    } else {
        WC()->cart->add_to_cart($product_id, $quantity);
    }
    wp_safe_redirect(wc_get_checkout_url());
    exit;
}
add_action('wp_loaded', 'sbw_wc_handle_buy_now');

// Add "Buy Now" button after the "Add to Cart" button
function sbw_wc_add_buy_now_button_single()
{
    global $product;

    if (!$product || !is_a($product, 'WC_Product')) {
        return;
    }

    printf(
        '<button id="sbw_wc-buy-now-button" type="button" data-product-id="%d" class="single_add_to_cart_button buy_now_button button alt">%s</button>',
        esc_attr($product->get_ID()),
        esc_html__('Buy Now', 'sbw-wc')
    );
}
add_action('woocommerce_after_add_to_cart_button', 'sbw_wc_add_buy_now_button_single');

// Handle Buy Now request
function sbw_wc_handle_buy_now()
{
    if (!isset($_POST['sbw-wc-buy-now'])) {
        return;
    }

    WC()->cart->empty_cart();

    $product_id = absint($_POST['sbw-wc-buy-now']);
    $quantity = isset($_POST['quantity']) ? absint($_POST['quantity']) : 1;
    $variation_id = isset($_POST['variation_id']) ? absint($_POST['variation_id']) : 0;

    if ($variation_id) {
        WC()->cart->add_to_cart($product_id, $quantity, $variation_id);
    } else {
        WC()->cart->add_to_cart($product_id, $quantity);
    }

    wp_send_json_success(['redirect' => wc_get_checkout_url()]);
    exit;
}
add_action('wp_ajax_sbw_wc_handle_buy_now', 'sbw_wc_handle_buy_now');
add_action('wp_ajax_nopriv_sbw_wc_handle_buy_now', 'sbw_wc_handle_buy_now');

jQuery(document).ready(function ($) {
    $('#sbw_wc-buy-now-button').on('click', function () {
        var productID = $(this).attr('data-product-id');
        var quantity = $('input[name="quantity"]').val() || 1;
        var variationID = $('input[name="variation_id"]').val() || 0;

        $.ajax({
            type: 'POST',
            url: wc_add_to_cart_params.ajax_url,
            data: {
                action: 'sbw_wc_handle_buy_now',
                sbw-wc-buy-now: productID,
                quantity: quantity,
                variation_id: variationID,
            },
            success: function (response) {
                if (response.success && response.redirect) {
                    window.location.href = response.redirect;
                }
            },
        });
    });
});
