Session var not maintaining across pages

[jamessmb]

Hi,

Can someone tell my why this Session var isn't being saved?

// set here
$HTTP_SESSION_VARS['sv_adCatText'] = $row_GetCatText['category'];
if($_POST['selCat'] == "9"){
header("Location: " . "CreateAdBook.php");
exit;
}else{
header("Location: " . "CreateAdNonBook.php");
exit;
}

//CreateAdNonBook.php

<td><?php echo $HTTP_SESSION_VARS['sv_adCatText']; ?></td>

I get this error:
Notice: Undefined index: sv_adCatText

If I do this in the first page:
$HTTP_SESSION_VARS['sv_adCatText'] = $row_GetCatText['category'];
echo $HTTP_SESSION_VARS['sv_adCatText'];
exit;

sv_adCatText echo's correctly.

If I do:
<?php
var_dump($HTTP_SESSION_VARS);
?>

on the second page, I see all the Session vars but not the one I want.

Thanks,
James

I certainly hope you're using session_start() as the very first thing on your page. Also, not that it is of supreme importance, but you can access the session variables with $_SESSION replacing $HTTP_SESSION_VARS.

The behavior of PHP sessions has be changed quite a bit in recent releases for security reasons. I'm not sure that $HTTP_SESSION_VARS[] will be stored even WITH session_start() at the top of the page.

As Ravenous suggests, you should be using the superglobal array $_SESSION[] in all cases.

After staring at it for an hour, i finally realized I had misspelled session_start().

So are you saying that I should use $_SESSION instead of $HTTP_SESSION_VARS?

Thanks,

$_SESSION is a superglobal array, always globally available, and does not need to be declared inside a function.

I would not be surprised to see some of the old notations deprecated, then deleted in a future release of PHP.
