session related

Hi,

I am not sure if this is the correct forum for this question but one of you might have experienced the same.

In results.php I have a table with an onClick event to overview.php.

Inside the table I have a button to hotlist.php.

in hotlist.php I have a button to either overview.php or results.php (session variable $previousUrl).

in results.php $previousUrl is set to "results.php", in overview.php to "overview.php".

When I am in results.php and click the button to hotlist.php, apparantly the table onClick event to overview.php is first triggered (although this is not visible as the next page is hotlist.php) because variable $previousUrl has become "overview.php" which is wrong!

Does anyone has a trick to fix this problem?

Thanks,
Ron

I all you want to do is store the URL for the previous page, you can use the $_SERVER['HTTP_REFERER'] (prior to v4.1 use $HTTP_SERVER_VARS array) variable to retrieve the previous URL, but, this will return a URL from another site if someone links to your page.

There are other ways of retieving the REFERER without a session, just add the URL to your links like so:

then check it on the next page with:

if ($_GET['referer']) {
// do some stuff
}

or for details on session_start() chack out

Thanks,

Yes, I did try that. From results.php to shortlist.php it works. But if I want to delete a form item in shortlist.php and reload the page (same structure table with onClick event to overview.php and remove button inside the table), $previousUrl is changed to overview.php while it should still be results.php!

So ideally I would like to set $previousUrl on the referer page itself so it can never change. I need to find a way to stop the onClick event in the table when a button inside the table is clicked.
