sessions again

[stuartc1]

Hi,

Sorry about this, but this is a real pain.

I have been trying to give a session variable a new value from the url querystring and finding it impossible.

example:

test.php -
<?
if (!(session_is_registered("testvar_session"))) {
session_register("testvar_session");
}

if (!(isset($testvar)))
{
$testvar_session = 5;
}
else
{
$testvar_session = $testvar;
}
echo $testvar_session;
?>

<a href="test.php?testvar=1">Test 1</a><br>
<a href="test.php?testvar=2">Test 2</a><br>

does anyone have any suggestions?

Thanks very much.
SC

do you need a call to session-start to be able to register a session variable?

I found the problem - the page that changed the session variable uses a function to build up pages, and the session is unavailable in these pages for some reason.
I have just passed in the value to the function and it works now. cheers
