Quirky Sessions - Variables not Coming back!

akido

Something is strange with my sessions - I'm not sure if its a code problem, but I'm pretty sure it's a server problem because my session code works on an external server but not mine (I just installed it a few days ago).

Anyways, none of the variables come back from the session, I can register 'my_var' but when I call it, it's empty. Sometimes the session register variables dont appear to register at all after opening up the sess files

Code:

<?php

session_start();

$my_var = "I like to watch the grass grow";
$my_var2 = "But I hate watching cows!";

# display them for the heck of it
echo "Variable 1: ".$my_var." - Variabe 2: ".$my_var2;

# set variables into a session format
session_register('my_var');
session_register('my_var2');

# display link to next page:
?>
<a href="sessions.php?a=2">Page 2</a>
<?php
if($_GET['a'] == 2) {
	# output the variables:
	echo "<br><br>Variables (but called from the session):<br>Variable 1: ".$_SESSION['my_var']." - Variable 2: ".$_SESSION['my_var2'];

}
?>

Thanks in advance.

From the manual.

If you are using $_SESSION (or $HTTP_SESSION_VARS), do not use session_register(), session_is_registered() and session_unregister().

How do I set them then?

(im sure this is so easy im just being stupid)

I got that to work using this code:

<?php

session_start();

$my_var = "I like to watch the grass grow";
$my_var2 = "But I hate watching cows!";

# display them for the heck of it
echo "Variable 1: ".$my_var." - Variabe 2: ".$my_var2;

# set variables into a session format
$_SESSION['my_var'] = $my_var;
$_SESSION['my_var2'] = $my_var2;

# output the variables:
echo "<br><br>Variables (but called from the session):<br>Variable 1: ".$_SESSION['my_var']." - Variable 2: ".$_SESSION['my_var2'];

?>

however -

1 - does this actually work, how I set them? Is this the right way to set the sesion vars?

2) - The reason it wasnt working before is because I had register_globals off, so I turned them on and it works, but I want to code with them off, that's the whole point 🙂

3) is there anything else about sessions I should know?

From what I understand, the way you have changed it to is "the way it's now done". I have come on a similar track to you. I'm guess you already know since you have it working, but I'll state it just in case:

You can set a session val: $SESSION['varname']=$varname
And get a session val: $varname=$SESSION['varname']

I think it is done like this to encourage OO, but that's just a guess.

How did you turn register_globals back on?

Also, something that might come in handy is $_POST['varname']. This was anotherone I had to implement after ugrading my server.

I'm curious: what are you running? OS & dist(if applicable)
I'm using Redhat 9.0

Hey, I already use $POST and $GET, but since I had register_globals on or whatever I didn'tsee the actual results!

You turn it back on by editing whatever file you use to configure php (in my case, php.ini) and find register_globals = <On/Off>

I'm using Windows XP PRO, I tried linux mandrake but since I need my modem to work and I could never get it working I gave up and went back to windows XP.
