SESSIONs = !BACK ?

Jimmy_xx

Hey, I use sessions for storing the users navigation information as they move around my websites. This however means that when the user clicks the back button of the browser it just goes back to the same page (index.php) but the session hasnt rolled-back so the user sees exactly the same thing.

an example of this is:
goto one of my site:

1) http://www.reality-creations.com/
2) click on "internet services"
3) click the back button

you will see your still on internet services.

does anyone know a way around this?

thanks very much !

Hard to say how your system is set up with the little info you provided.

However, $_SERVER['HTTP_REFERER']; will return the last URL.

So, in your index.php:

if ($_SERVER['HTTP_REFERER'] == 'http://www.reality-creations.com')
$_SESSION['SomeSession'] = '';

However, it's hard to say when we know so little about how your page works.

my index.php file is the only file which ever is called. It displays the relevant area of the site by reading which variables are set in my session.

I have tried to explain it simply below:

is the area set in the session?
no: include the area selection page
yes:

is the sub area set in the session?
no: include the sub area selection page
yes: include the sub areas file

so in effect, on my original post when you click internet services, its selected a different area and the default sub area and then the 'internet services' sub menu item. All running from the index.php.

I hope thats made it a little clearer 😕

thanks!

When the back button in the browser is clicked, does it re-send the URLs?

If it does, you have to validate the variables and clear the session if the variable is empty, which it should be when the user clicks back enough times til it hits the welcome page.

If the browser simply loads the pages from cache without re-sending the URLs then it's beyond your control, and you'll have to re-design your system.

Instead of using frames you could simply set up a table and include different pages in the different cells.

That would of course make your left menu non stationary, but other than that, it shouldn't have any impact on the page.

Hope this helps,
