Update Woocommerce cart after adding a product (jQuery)

Question

The Ajax seems to work just fine but the cart content won't refresh as expected. I want the contents of the cart to be refreshed once the "add to cart" button is clicked. As it is now, I have to refresh the page manually to see the added products.

I'm using this function to add a product to my woocommerce cart:

      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){
                    console.log("Product added");
                }/*,
              dataType: 'JSON'*/
            }); 
      }

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

Is it possible to refresh only the cart after a product was added?

Answer 1

This is possible - you need to use a modified version of this code:

http://docs.woothemes.com/document/show-cart-contents-total/

Edit - in case of future 404's

<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;

}

Do you mind if the ajax request "automatically" refreshes the page on its own? then you could try something like this... (untested).

 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'*/
            }); 
      }
