SESSION HELL.... Please Help.

jscnet

I'm having a nightmare experience -- Sessions!

Here's what I'm trying to accomplish:
I want to store my variables in a session, so that I can access them from page to page -- I want to avoid using hidden fields.

I've set the session.cache_limiter to = "" -- this has the effect of allowing the Caching to working normally, which I want.

Now, on (say) FORM1 (page1), I enter in some data, I then click my Submit button and go to FORM2 (page2) -- the SID doesn't transfer over.. annoying..

When I click my browsers back button, to go to FORM1 again -- if I make a change, and press Submit -- the data in my Session DOES NOT get updated (ie. does not reflect the change.)

Instead of using SID on each page, I am using session_id() and session_name() to reference the session. As SID doesn't seem to work from page to page.

So -- I want the functionality of someone being able to press their BACK button, make a change, then press submit and have those changes updated in the session file.

Please help -- this is insane and not at all working as I'd expect it to.

Thanks.

You need to make sure that you kill the variable, the resave it.

$var1 = "";
session_register("var1");

$var1 = "this";
session_register("var1");

This is how I got around that problem.

i'm confused as to how i would 'kill the variable' when i'm using my browsers BACK button?

thanks.

I am not sure if you are using session_start() on the page after form submission. This has to be the first statement on that page (even before sending the html header or connecting to db).

I am passing session data across quite successfully. If it doesn't work, let me know

Yes. I have session_start() at the very top of each page, along with session_register(...all my variables...) on each page, just below session_start().

Now -- it should work right? -- I mean, when I initially enter data into the form and press submit, the data IS sent to the session file -- however, when I press my browsers back button and (say) add something to another field or make a change to an existing field, then press submit ... the data isn't updated... and it also looks like I lose the SID constant, thereafter.

If I never press my browsers back button, the SID constant stays with me.

I would like to get this functionality (ie. allowing the user to press their back button, and having the session file update) -- working.

Now, remember, I have enabled normal caching... so, my forms / pages are cached. I am not using 'nocache', 'public', or 'private' -- although, enabling any of those doesn't seem to fix the problem... and 'nocache' is what I'm trying to avoid.

FYI: I am running this all on IIS 5.0 (Win2000 sp1), with PHP 4.05. I am also using the POST method on all my forms.

Thanks.
