Is there a way to automatically apply a coupon code?

[valtinho]

I need to apply a coupon code automatically based on the affiliate ID.

How could I do this?

Thanks in advance!

You can check the affliate id on the page where you want to apply the coupon. Depending upon the affliate you can apply some coupon. For example

Code: Select all

protected void Page_Load(object sender, EventArgs e)
    {
        if (Token.Instance.User.AffiliateId == 2)
            ApplyCoupon("coupon-code");
    }

private void ApplyCoupon(string couponCode) 
    {
        if (String.IsNullOrEmpty(couponCode))
            return;
        Coupon coupon = CouponDataSource.LoadForCouponCode(couponCode);
        String couponValidityMessage = String.Empty;
        if (coupon != null)
        {
            if (!CouponCalculator.IsCouponAlreadyUsed(Token.Instance.User.Basket, coupon))
            {
                if (CouponCalculator.IsCouponValid(Token.Instance.User.Basket, coupon, out couponValidityMessage))
                {
                    Basket basket = Token.Instance.User.Basket;
                    BasketCoupon recentCoupon = new BasketCoupon(Token.Instance.UserId, coupon.CouponId);
                    basket.BasketCoupons.Add(recentCoupon);
                    
                    // APPLY COUPON COMBINE RULE
                    //THE RULE: 
                    //If most recently applied coupon is marked "do not combine", then all previously
                    //entered coupons must be removed from basket.

                    //If most recently applied coupon is marked "combine", then remove any applied
                    //coupon that is marked "do not combine".  (Logically, in this instance there
                    //could be at most one other coupon of this type...)
                    string previousCouponsRemoved = "";

                    if (recentCoupon.Coupon.AllowCombine)
                    {
                        //IF ALLOW COMBINE, REMOVE ALL PREVIOUS NOCOMBINE COUPONS
                        for (int i = (basket.BasketCoupons.Count - 1); i >= 0; i--)
                        {
                            if (!basket.BasketCoupons[i].Coupon.AllowCombine)
                            {
                                if (previousCouponsRemoved.Length > 0)
                                {
                                    previousCouponsRemoved += "," + basket.BasketCoupons[i].Coupon.Name;
                                }
                                else
                                {
                                    previousCouponsRemoved = basket.BasketCoupons[i].Coupon.Name;
                                }

                                basket.BasketCoupons.DeleteAt(i);
                            }
                        }
                    }
                    else
                    {
                        //IF NOT ALLOW COMBINE, REMOVE ALL EXCEPT THIS COUPON
                        for (int i = (basket.BasketCoupons.Count - 1); i >= 0; i--)
                        {
                            if (basket.BasketCoupons[i] != recentCoupon)
                            {
                                if (previousCouponsRemoved.Length > 0)
                                {
                                    previousCouponsRemoved += "," + basket.BasketCoupons[i].Coupon.Name;
                                }
                                else
                                {
                                    previousCouponsRemoved = basket.BasketCoupons[i].Coupon.Name;
                                }
                                basket.BasketCoupons.DeleteAt(i);
                            }
                        }
                    }

                    basket.Save();
                    basket.Recalculate();
                }
                else
                {
                    //Invalid Coupon

Thank you so much, it worked perfectly!

[saiho01]

that's pretty convenient, where should I put that code?

It depends upon requirement, for example have a look at following thread

Those are exactly what I was looking for! I have a few more questions though, bear with me here. These are the 3 conditions I am trying to implement into our shopping cart.

1)introduce a continual 30% discount for subscribers to our service.
2)one time 30% discount for non-subscribers
3)expiration date for the coupon (see it as an introductory discount)

So the question is, what can I do to accomplish that? And if I used the same coupon for both subscribers/non-subscribers with an expiration date within one week, what would happen to the price for subscribers after that?

Thanks
