Any of those methods can work.
1. You can pass it through the address bar, if you want to use links. This is the usual method for using "paging" techniques--- "?page=1", etc., and you can just multiply $_GET['page'] by 12.
2. Forms work fine, if you are certain a user will be submitting one. If not, best not to use them because you'd need a backup method anyway.
3. Just start a session, store $_SESSION['var'] = 12;, and move on from there. However, this is not a way to track what pages they came from, where they go next, etc. You could also try that: $_SESSION['var'] = 'currentpagename';

I don't know exactly what you are trying to do, so go ahead and use whatever method is easiest to make work.

I would suggest using get variables, because they are fairly easy to use and they are reliable. It know it makes the page urls look kinda funny, but they are useful and this is how many websites keep track of "location"-- look at this forum, for instance. Any time you have numerical data that changes the content of a page while using the same script, get vars are a great way to go.

The other option here is to do something else entirely:
You could use server side includes (like php's include()) to keep a common script on all of the pages. Then that script could take the page's value-- like "page1" or "page2", as you set it, and decide what to do with "12" from that.


The real question you need to answer is which you want:
1. A system that changes "12" based on the page you are on? (I suggest get vars or the include() idea)
2. A system that changes "12" based on the previous page? (I suggest sessions, or maybe get vars)
