Tracking state in a slideshow

[greta]

Hello 🙂

I've created a simple slideshow, using url parameters to keep the state, like in this sample:

http://mysite.com/mypage.php?slide=3

Now I'd like to use something more elegant; the best I could come up is a solution in which
every action ('next','prev') points to a separate php file manipulating session variables.
See code:

<?php // back.php

session_start();

if (isset($_SESSION["slide"])) $_SESSION["slide"]--;

header("Status: 301 prev slide");
header("Location: mypage.php");

?>

I'm sure there are many other ways; I'm not really satisfied with this approach.
Anyone with a better solution?
TIA, Greta

To be honest, if you want a variable to go through page to page, use cURL to do it. But, for what you want, cURL seems impractical. Most likely what you originally had: stage=1, stage=2 ...; is your best bet. And it's not a bad idea, and it doesn't look sloppy.

Thanks for replying 🙂

Being a newbie, when reading your post I hadn't the slightest idea of what cURL was.
After reading the faqs and a couple of articles however, I still can't understand how
I could benefit from it (am i really that dumb?).
Can you add a few words on the topic?

Thanks again, Greta

cURL is just generally good for posting vars to another script without showing them in the URL.

They wouldn't be of help here, but for future reference (as I can see you asking how to post vars from a script).
