Form + GET

Hey everyone,

I’ll try to explain, as clearly as I can, the problem I’m facing.
I have a page, view.php. It allows people to view data out of the data base. You can call view.php with GET parameters, so it’s able to be bookmarked. For example: view.php?mode=shows, view.php?mode=episodes.

The latter, view.php?mode=episodes, lists all episodes in the database. Just above the data table I want a dropdown, with all the shows in the database, allows the user to click one of the shows, and the site would filter to only show episodes of that show. But I want people to be able to bookmark the page with the filter too, so I don’t want a form with a dropdown, and POST the information. I want the page to read, for example, view.php?mode=episodes&s=6, 6 being the ID of the show.

So on the view.php?mode=episodes, I want a dropdown menu with all existing shows (working fine). I want a user to be able to select a show, and then the site would filter all episodes for that show, and the user should be able to bookmark it. What’s my best option here?
Any questions, just ask.
