Prevent fake add to cart links
edited March 2012
How does FoxyCart prevent fake add to cart links? Anyone with a little understanding of websites can recognize the pattern of text links that add items to cart and just put in their own price. What prevents this?
For what it's worth, in all the years that FoxyCart has been running, there has only actually been a couple confirmed reports of this happening.
That said though, we have implemented a feature called HMAC Validation that allows you to encrpyt your add to cart forms in such a way that they can't be openly tampered with. For notes on how to set that up, see this page:
