A client wanted to generate an .ics (add to outlook calendar) link from an appointment request form on his website. The site is in WordPress and we use gravity forms.
This is the final code I ended up using in the page template for my forms confirmation page. I had to set up the confirmation as a redirect and pass the necessary variables first (anytime you see me using $_GET in the code).
