Proper syntax for ft_api_check_submission_is_unique IP Address check

[fourmat]

I am trying to make sure that form submissions are unique with both email and IP address verification. I currently have the verification for the email address working, but I am wondering what the proper syntax is for the $criteria array using IP address: eg:

current

PHP Code:

$criteria = array(
  "col_19" => $_POST["Email"]
); 


would it be?

PHP Code:

$criteria = array(
  "col_19" => $_POST["Email"],
  "ip_address" => $_POST["ip_address"]
); 


I guess my confusion is that the form isn't actually posting the ip address as a hidden field and FT seems to be adding the IP field, so I'm not sure how to structure the variable name.

Hi fourmat,

Good question! You had the syntax right, just not the way of extracting the user's IP address. Try this:

PHP Code:

$criteria = array(
  "col_19" => $_POST["Email"],
  "ip_address" => $_SERVER["REMOTE_ADDR"]
); 


Let me know if that doesn't work!
