How to Refresh Checkout Page WooCommerce

Update woocommerce checkout order detials with jquery or php

jQuer - 

    jQuery('body').trigger('update_checkout');
    
    
  /* to update info on your checkout page, you need to trigger the update_checkout function
     so add this in your javascript file for your theme or plugin
  */
  /* what this does is update the order review table but what it doesn't do is update shipping costs;
     the calculate_shipping function of your shipping class will not be called again;
     so if you were like me and you made a shipping method plugin, and you had to change costs based on the payment method, then
     this is the only way to ensure it does just that
  */

php - 

  <?php

    # add this in your plugin file, and that's it, the calculate_shipping method of your shipping plugin class will be called again

    function action_woocommerce_checkout_update_order_review($array, $int)

    {

    WC()->cart->calculate_shipping();

    return;

    }

    add_action('woocommerce_checkout_update_order_review', 'action_woocommerce_checkout_update_order_review', 10, 2);

  ?>
