这是可能的-您需要使用此代码的修改版本：
http://docs.woothemes.com/document/show-cart-contents-total/
编辑-以防将来出现404

<a class="cart-customlocation" href="<?php echo wc_get_cart_url(); ?>" title="<?php _e( 'View your shopping cart' ); ?>"><?php echo sprintf ( _n( '%d item', '%d items', WC()->cart->get_cart_contents_count() ), WC()->cart->get_cart_contents_count() ); ?> - <?php echo WC()->cart->get_cart_total(); ?></a>

// Ensure cart contents update when products are added to the cart via AJAX (place the following in functions.php).
// Used in conjunction with https://gist.github.com/DanielSantoro/1d0dc206e242239624eb71b2636ab148
add_filter('add_to_cart_fragments', 'woocommerce_header_add_to_cart_fragment');

function woocommerce_header_add_to_cart_fragment( $fragments ) {
    global $woocommerce;

    ob_start();

    ?>
    <a class="cart-customlocation" href="<?php echo $woocommerce->cart->get_cart_url(); ?>" title="<?php _e('View your shopping cart', 'woothemes'); ?>"><?php echo sprintf(_n('%d item', '%d items', $woocommerce->cart->cart_contents_count, 'woothemes'), $woocommerce->cart->cart_contents_count);?> - <?php echo $woocommerce->cart->get_cart_total(); ?></a>
    <?php

    $fragments['a.cart-customlocation'] = ob_get_clean();

    return $fragments;

}

你介意 AJAX 请求“自动”刷新页面吗？那么你可以尝试类似这样的东西...（未经测试）。

function addToCart(p_id) {
            jQuery.ajax({
              type: 'POST',
              url: '/wp/?post_type=product&add-to-cart='+p_id,
              data: { 'product_id':  p_id,
              'quantity': amount},
              success: function(response, textStatus, jqXHR){
                    location.reload(true);
                }/*,
              dataType: 'JSON'*/
            }); 
      }

首先观察购物车中的html是什么，以及您需要哪些信息来完成该操作。例如，您的购物车可能看起来像这样：

<div id="cart">
  <form action="checkout" method="POST" id="cart_checkout_form">
    <table id="cart_table">
      <tr>
         <td> Product </td>
         <td> Qty </td>
         <td> Price </td>
      </tr> 
      <tr>
         <td> <input type="hidden" name="product_id" value="221321"/> Product 1</td>
         <td> 2</td>
         <td> 200 $</td>
      </tr>

    </table>

  </form>
</div>

现在，您的代码应包含以下更改以反映产品：

function addToCart(p_id) {
        jQuery.ajax({
          type: 'POST',
          url: '/wp/?post_type=product&add-to-cart='+p_id,
          data: { 'product_id':  p_id,
          'quantity': amount},
          success: function(response, textStatus, jqXHR){
                /* response should contain details required for adding to cart

                   like price quantity name etc in the json response */

                var new_product_html = "<tr><td><input type='hidden' value='"+ response.product_id +"' name="product_id"/>"+ response.product_name +" </td><td>"+response.product_qty+"</td><td>"+ response.product_price +"</td></tr>";

                $("#cart_table").append(new_product_html);

                console.log("Product added");

            }/*,
          dataType: 'JSON'*/
        }); 
  }

jQuery('#addToCart').click(function(e) {
  e.preventDefault();
  addToCart(prod_id["product_id"]);
  return false;
});

这将反映在获得产品添加到购物车。请阅读以下链接，如果你觉得困惑。Tutorial还有jquery append和 AJAX 函数在www.example.com更详细jquery.com

这似乎对我很有效，至少在我尝试过的主题上是这样：

jQuery( document.body ).trigger( 'wc_fragment_refresh' );
