session data getting lost

[jkmambo@gmail.com]

Session data is getting lost in PHP version 4.4.1 which used to work in
version 4.3.3

The code is similar to the one below

Assume the file is called count.php which requires a parameter
productid;

session_start() ;
if (!isset($_SESSI ON['countAccess'])) $_SESSION['countAccess'] = 0;
else $_SESSION['countAccess']++;

echo $_SESSION['countAccess'];


if I call the script with a parameter for example
count.php?produ ctid=78

when I press refresh button $_SESSION['countAccess'] does not get
incremented but if I call it without the parameter,
$_SESSION['countAccess'] gets incremented.
I am also losing data if I call another script.

Does anyone know what's going on here?

Thank you

Why don't you use {} to mark your logical blocks?
This is PHP, not python. ;-)

Like:
session_start() ;
if (!isset($_SESSI ON['countAccess'])) {
$_SESSION['countAccess'] = 0;
} else {
$_SESSION['countAccess']++;
}

echo $_SESSION['countAccess'];

That ?productid=78 has nothing to do with the SESSION.
It will appear in $_GET, not $_SESSION.
So this is very surprising.
Do you have more code, without {}, that might interfere?
If yes: fix it, and if the problem persists, show us the code.

Re: session data getting lost

Works for me on 3.3.10 and 4.4.1

Must be one of your settings or something elsewhere in the script

Re: session data getting lost

When you use one statement in an if-else block you dont need {} for all
C type languages. {} are only used to group statements

Re: session data getting lost

I apologize the problem was not with the parameter. The code is working
sometimes and other times it does not work whether I am using a
paramter or not. The first time I tested the ecript today it was not
working, then I addeda simple echo statement to display a string. Then
the script worked OK. This is the setting of my session in php.ini

Re: session data getting lost

I have discovered what the problem was. I installed Zone Alarm Internet
Security Suite and it appears its blocking the session information. I
have disabled it and the system is working fine now.

Re: session data getting lost

Sorry, still works every time, even with your ini file - could it be a
caching thing?

What OS and browser are you on?

Re: session data getting lost

The problem was being caused by zone alarm internet security software
blocking sessions. I do not understand why it's doing this for. I
wanted to buy it but now I will think twice before I buy it.
I thought the problem could have been due to my web hosting company
updating the PHP version and not setting up the session values
properly.
Thank you for taking your time to help me with this problem

No, you don't *need* them. However, I still add them in my code.
Overall it makes things more readable, IMHO.

It also means I don't have unanticipated problems when I add another
statement to a then or else clause.

Re: session data getting lost

Erwin as implying that the braces are required in PHP even for one
statement but which they are not. In my opinion its more legible not to
have the braces and the code looks shorter.

Re: session data getting lost

I'd do a single line "if" as

if (!isset($_SESSI ON['countAccess'])) $_SESSION['countAccess'] = 0;

but if I had an else, i'd probably use braces, but I'd lay it out:

if (!isset($_SESSI ON['countAccess']))
{
$_SESSION['countAccess'] = 0;
}
else
{
$_SESSION['countAccess']++;
}

And harder to follow and maintain....

Was it blocking the session cookie? If so, this is a more general problem.
