Hi,

Great module, it seems to be working well for us.

Problem

We have a banner ad on another site for a promotion we are running. Instead of giving the user a coupon they had to retype, I wanted the link to add the coupon / discount directly to their cart. The easiest way to do this is through rules.

The problem was that there is not a relevant action for adding a coupon to a specific order. I tried to use the '%off' action on each of the line items in an order, but this didn't get me anywhere. The other problem is that having a discount without a coupon code gets applied to every user, which is not what I wanted.

Solution

I modified the code to add the action. It was pretty straight forward and seems to be working, so I thought I'd share incase it's useful to anyone else.

Inside commerce_coupon.rules.inc

/*
 * Implements hook_rules_action_info()
 */
function commerce_coupon_rules_action_info() {
  $actions['commerce_coupon_apply_to_order'] = array(
    'label' => t('Apply a coupon to a cart order'),
    'group' => t('Commerce Coupon'),
    'parameter' => array(
      'coupon_code' => array(
        'type' => 'text',
        'label' => t('Coupon Code'),
        ),
      'commerce_order' => array(
        'type' => 'commerce_order',
        'label' => t('Order'),
        ),
      )
    );

  return $actions;
}


/*
 * Rules action callback: apply a coupon to given order
 */
function commerce_coupon_apply_to_order($coupon_code, $commerce_order){
  $error = '';
  commerce_coupon_redeem_coupon_code($coupon_code, $commerce_order, $error);
  if($error != ''){
    drupal_set_message(t('Error adding coupon: ' . $error), 'error');
  }
}

Hope this is useful to someone. Let me know if you decide to include it in your code base

You may want to use something like this for the action instead:

/*
 * Rules action callback: apply a coupon to given order
 */
function commerce_coupon_apply_to_order($coupon_code, $commerce_order){

  drupal_page_is_cacheable(FALSE);
 $user = $GLOBALS['user'];

  // Create new cart if no order exists for this user.
  if (!$commerce_order) {
    $commerce_order = commerce_cart_order_new($user->uid);
  }

  // Apply coupon to order.
  $error = '';
  $coupon = commerce_coupon_redeem_coupon_code($coupon_code, $commerce_order, $error);

  if ($coupon) {
    // Reload the order so it is not out of date.
    $commerce_order = commerce_order_load($commerce_order->order_id);

    // Recalculate discounts.
    commerce_cart_order_refresh($commerce_order);
  }

  if (!$error) {
    // If a coupon was invalidated during the cart refresh (e.g. if its
    // discounts failed their conditions), an error message will have been
    // set.
    $error = &drupal_static('commerce_coupon_error_' . strtolower($coupon->code));
  }

  if (!$error) {
    // Allow modules/rules to act when a coupon has been successfully added
    // to the cart.
    rules_invoke_all('commerce_coupon_applied_to_cart', $coupon, $commerce_order);
  }

}

tnx for this Rules...But it can only work with One Coupon Code.
how we can use unlimited Coupon code with this Rules action?
