Hey I´m trying to send a URL to customers where they already have products in the shopping cart.

I used this method


And it also adds a product but somehow it doesn´t show up, see image below.

No product is in the cart

Any ideas?

  • What have you tried so far to debug? Are there any errors? Does it work via the normal add to cart way?

  • On other pages the product add to cart works fine.

  • I wonder if the form_key is expiring

  • Yes, ditch form_key, it's session dependent. And use uenc parameter if you need it. It contains a go back url encoded. Sep 7, 2015 at 10:17
  • I´ve tried to remove the form_key but have the same result. What is the uenc parameter?

That worked for me. Sadly I can´t use the product SKU which I hoped for.
