I'm trying to do something like this:
I want every first time visitor to my site to be redirected to a registration page(for a mailing list, not site registration) and after the registration to be redirected to a thankyou page where a cookie will be set to prevent this process to happen on the next visit to my site.
I created a function for creating a cookie if it doesn't exist in the functions.php file and I also call it there.
Here are the problems I still have:
1. I want the cookie to be set only in the thankyou page. I tried doing it with a condition in the function "is_page(3)" but the page id is not loaded yet when functions.php is loaded.
2. Maybe this is a beginners question: how do I redirect to another page from within the wordpress page?
*The redirection from the registarion to the thankyou page are done automatically by the mailing list registration butoon so I don't need to do anything there.
Thanks in advance
