I've been looking for the sample code for this but haven't find on yet.
Could you please help me find a method or exact sample code that will do the following:
I have a regular "contact us" form and some other forms that corrects my customer's name, email address etc. In these forms, I'd like to add a check box that says "Please add me to your e-newsletter" and if this check box button is added, this customer's name, email address will be opted-in (adds to constant contact database).
How to accomplish this task? I'd so appreciate your help.
