Php Session Error

mthirumalai

I have the code listing for a page 'general1.php'. This page has a few 'include' files.

The session is created in the previous page and hence is available in this page. The session variable '$SESSION['ROOT'] is available in ' include($SESSION['ROOT']."util/dbUtils.php") line.

The next line is include($_SESSION['ROOT']."menu/navigationlinks.php");

This navigationlinks.php has another include within it and is ccoded like this:
"include include ($_SESSION 'ROOT']."globals/global_def.php");

In this line, I get an error that '%_SESSION' is undefined. I checked and the session id was null within 'navigationlinks.php'

How to fix this error? Am I doing anything wrong here.

Please help.

---- Code Below ---

<? session_start();
// echo 'General One SessionID is ' . session_id();
?>
<html><link rel="stylesheet" href="<? echo $_SESSION['SITEROOT'].'Style/style.css';?>" type="text/css" />
<head>
<title>Title One</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>

include($SESSION['ROOT']."util/dbUtils.php");
// echo 'General One SessionID is ' . session_id();
include($SESSION['ROOT']."menu/navigationlinks.php");
include ($_SESSION['ROOT']."menu/content_menu.php");
nav_menu('top');
<br>';
?>
<table width="100%" cellspacing="0" cellpadding="0">
<tr>

<?
$channel = $GET['id2'];
$label = $GET['id1'];
// echo $channel.' '.$label;
format_page2 ($channel, $label);
?>

   <? include ($_SESSION['SITEROOT']."footer.php")?>
</td>

</tr>
</table>

</body>
</html>

Not 100% sure of the problem but noticed;

This navigationlinks.php has another include within it and is coded like this:

include include ($_SESSION 'ROOT']."globals/global_def.php");

Contains a typo and should be:

 include ($_SESSION['ROOT']."globals/global_def.php");

Also whats the difference between $SESSION['ROOT'] and $SESSION['SITEROOT'] ??

Thanks Rosco.

Theh code is indeed 'include $_SESSION['ROOT']......'. there'sonly one 'include'.

I still get the error in session being lost.

<Page1>
session_start();
include a.php
include b.php
include c.php
include d.php
</page1>.

This is the structure. The session is not availale in c.php. What could be the reason?

The differnece between SITEROOT and ROOT - is for IIS local testing. SITEROOT is the directory path while ROOT is the url path.

Any help will be greatly appreaciated.

Very Bizarre - not seen that before.

What code do you have in page c?

Anything that is effecting / using the session?

Includes basically force all the code in the file to read as if it was in file - so if its available at the start then Page B or Page C is doing something to corrupt it..

mthirumalai

The first line in file C is (there are seven lines in the beginning that are commented out...)

include ($_SESSION['ROOT']."globals/global_def.php");

here it says that SESSION is undefined...
The actual error is
Undefined variable: SESSION in c:\inetpub\wwwroot\SRMI\menu\navigationlinks.php on line 8

thanks

If you comment out that line - and do a:

print_r($_SESSION);

Do you get the same error ?

mthirumalai

Yes.

I commented the 'include' and included the 'print_r..'

I got the following error on this print_r line..
Notice: Undefined variable: _SESSION in c:\inetpub\wwwroot\SRMI\menu\navigationlinks.php on line 7

thanks

OK - how about doing the print_r just before you do the include c?

Does it still error?

mthirumalai

The print_r lists all the session var before the 'include c'.

Only within C - it does not see the session....

Hi,

do you have a unset($_SESSION) line in any of the scripts ? If not then post the scripts as attachment (zip) so we can look a little deeper into the code.

The test code is enclosed as a zip file.

There is no unset in the code.

Thanks for your offer to help.

OK I had to do a little debugging change the short quotes <? to <?php

and the redirect didn't work for me - so I included the index.php code in the general code.

Two typos - include ($_SESSION['ROOT']."test25.php");

There is no test25.php - changed to test24.php.

Also test24.php starts with two open quotes:
<? <?

Once I fixed them it worked fine and the session was available throughout!
