1 line changes to nop with significant impact

1) Product.aspx.cs line 72+ add in:

if (product.MetaDescription == "")
                product.MetaDescription = product.ShortDescription;

I.E if product SEO is blank use description

2) /Templates/Products/* - Change product title to <h1>

3) CheckoutPaymentMethod.ascx.cs

If there is only 1 checkout method, automatically select it:

Line 208:

else if (boundPaymentMethods.Count == 1)
            {
                phSelectPaymentMethod.Visible = true;
                pnlPaymentMethodsError.Visible = false;
                dlPaymentMethod.DataSource = boundPaymentMethods;
                dlPaymentMethod.DataBind();

                // Theres only one paymeny method, so no point in asking the user to select it

                int paymentMethodId = boundPaymentMethods[0].PaymentMethodId;
                var paymentMethod = PaymentMethodManager.GetPaymentMethodById(paymentMethodId);
                if (paymentMethod != null && paymentMethod.IsActive)
                {
                    NopContext.Current.User = CustomerManager.SetLastPaymentMethodId(
                        NopContext.Current.User.CustomerId, paymentMethodId);
                    var args1 = new CheckoutStepEventArgs() {PaymentMethodSelected = true};
                    OnCheckoutStepChanged(args1);
                    if (!this.OnePageCheckout)
                        Response.Redirect("~/checkoutpaymentinfo.aspx");
                }
            }

4) CheckoutBillintAddress.ascx.cs

When clicking Use Same as Shipping address button use this:

SelectAddress(billingAddress);

This will automatically select the address for the user and move to next step. Rather than copying values then having to click next.

Thanks

Could you explain how to skip the payment method for version 1.9?

There is no more PaymentMethodManager.

The code has a comment:
//or you can select it and go to the next step of checkout

but I don't know how to actually select the only available payment method.

Your help is much appreciated.

in v1.9  the payment method is automatically skipped if the order total is 0.00
