sessions within functions

[magicpants]

Has anyone else had problems setting sessions whilst within functions? I seem to be only able to set session values whilst out of a function. Anyone?

not me

how do you set session variables?

do you use $_SESSION instead of session-register?

[magicpants]

Here is the code that I am using:

session1.php...

<?
session_start();
setsession();

//---------------------------------------------

function setsession() {

$HTTP_SESSION_VARS['session_var'] = "hello";

}

?>

<a href="session2.php">next</a>

session2.php...

<?
session_start();
getsession();

//------------------------------------------------

function getsession() {
echo "val".$HTTP_SESSION_VARS['session_var'];
}

?>

try using $_SESSION instead of $HTTP_SESSION_VARS

[magicpants]

That seems to do the trick. Thanks.

But why shouldn't $HTTP_SESSION_VARS work?

Cheers

$HTTP_SESSION_VARS is a variable like $fubar and therefore has to be imported into a function's namespace using global

$_SESSION is a superglobal array that youdon't need to import into a function's namespace

OK. I understand now.

Thanks for your help.
