session_register in php_lib_login_includes

[hodges]

I am working with frymaster's php_lib_login_includes database library and postgresql.

When I updated to Redhat 8 and the current php (and postgres)
it appears that the session functions broke (they are from adodb
so I tried the most recent).

Note, also needed changes in how form data was passed, now you have to use $_POST.

When ever the main library file is loaded we have
session_register('gUser');
It appears that $gUser is not being saved or made available. Has
anyone got this library working with current versions of php and
postgres?

Thanks,
Tom

I also got the sample session script from
http://trios.org/php/sessions/

It does not run correctly, the login page never loads so the
if(!auth()): line is failing.

This may be related to my issue with php_lib_login

This really simple session script also fails to increment.
<?
session_start();
session_register("SESSION");

if (! isset($SESSION)) {
$SESSION["count"] = 0;
echo "<li>Counter initialized, please reload this page to see it increment";
} else {
echo "<li>Waking up session $PHPSESSID";
$SESSION["count"]++;
}
echo "<li>The counter is now $SESSION[count] ";
?>

$SESSION

shouldn't that be $_SESSION?

and btw, in PHP <4.3 it is not allowed to mix session_register with $_SESSION, it will mess up.

Hmm, this actually works. Now to figure out php_lib_login session
function.
Thanks, Tom

<?
session_start();
session_register("_SESSION");

if (! isset($SESSION))
{ $SESSION["count"] = 0;
echo "<li>Counter initialized, please reload this page to see it increment";}

else
{ echo "<li>Waking up session $PHPSESSID";
$SESSION["count"]++;}
echo "<li>The counter is now $SESSION[count] ";
?>

egh no 🙂

$_SESSION completely replaces session_register() in PHP 4.2 (or was it 4.1 already)

<?
session_start();
if (! isset($SESSION['count']))
{
$SESSION["count"] = 0;
echo "<li>Counter initialized, please reload this page to see it increment";
}
else
{
echo "<li>Have woken up session ".session_id();
$SESSION["count"]++;}
echo "<li>The counter is now $SESSION[count] ";
?>

I think this is the code in php_lib_logins that needs replacing

session_register('gUser');
if (empty($gUser)) $gUser = '';

with

session_start();
if (! isset ($_SESSION('gUser')
{
$gUser = '';
}

Does that look equivalent?

allmost.

vars never ever leave the $SESSION array, so whenever you want to work with a var that's in a session, you must access it through $SESSION:

<?
session_start();
if (! isset ($SESSION['gUser']))
{
$SESSION['gUser'] = '';
}
?>

[EDIT] array's, so use [] and not ()

[hodges]

$gUser is referenced in about 20 functions as a GLOBAL in the file
login.inc.php
I put this in one function:

$gUser = $_SESSION['gUser'];
echo "gUser= $gUser in line 306 <BR>\n";

and it seems to be working. Should that establish $gUser for global use in the other functions?

Thanks again for the great pointers!

BTW
Linux + Apache + PHP + PostgreSQL = success
That's faulty
Should be
Windows + Apache + PHP + MySQL = Success

No, not really,

Windows + Apache + PHP + MySQL = your worst nightmare.

But I won't get into a MySQL vs PostgreSQL argument here. If you want to know more about it, let me know and I'll give you some undeniable arguments why mysql = bad and postgresql = good.

[hodges]

This seems to have fixed it:

session_start();
if (! isset ($SESSION['gUser']))
{$gUser = '';}
else {$gUser=$SESSION['gUser'];}

Now the php_lib_logins_include library seems to work with current
php, postgresql, and redhat 8.

Thanks for all the help and suggestions.
