Setcookie to keep my event calendar filters?

[Kritter5x]

Hi, I have built an event calendar and whipped up some basic event filters to use in it. All of that works fine, but i've had people complain that as soon as they switch pages, it resets any filters or months they might have jumped too. It was suggested to use Setcookie functions to keep chosen filters etc, but I can't for the life of me get it working properly no matter where or how I use them. I'm still learning most of this stuff and i'd like to get this working. Any suggestions or taking a look at my code would be fantastic.

Try storing it in a session.

[mac_gyver]

pass your filters that determine what is displayed when you make a get request for a page as $_GET parameters in the url. that's what $_GET parameters are designed to do.

 

this will allow someone to bookmark the page and return to the same point later or to share a link to the results or to even try different searches and can navigate back to any point as long as the visited pages are still in their browser history.

Unfortunately i'm not sure how to really do either of those suggestions, at least in the code I have.
