Sessions without 'register globals' on.....

drucifer

I used to use sessions with Register Globals enabled but am trying to get to grips with the 'new' way whilst using PHP 4.3.2.

I have managed to register a variable using $_SESSION['variablehere']; and can call and output it on the same file. BUT I would like to be able to call the same variable on an include file within this but it never shows....can i do this?

In fact it I don't think the variable IS registering at all and was only outputting as it was assigned on the same page...

Maybe some code would help, I'm using this code to start the session from a form:

[FONT=courier new]session_start();

$var_user = $POST['SESSION_USER'];
$var_pass = $POST['SESSION_PASS'];

$SESSION['SESSION_USER'] = $var_user;
$SESSION['SESSION_PASS'] = $var_pass;[/FONT]

Am I way off?

Well, that should set it all correctly. Show what you're doing to get the vars out.

When setting, use $SESSION['var'] = 'value';. When checking it, use $SESSION['var']:
echo $_SESSION['var']; // echos 'value'

If that looks like what you tried, try showing some code.[/Old post]

I'm using this, but as I mentioned in my amended post, the variables don't seem to be registering at all?

[FONT=courier new]$SESSION_USER = $_SESSION['SESSION_USER'];

echo $SESSION_USER;[/FONT]

Try narrowing things down: scripts that are (a) as small as possible (to reduce the number of distractions and red herrings) and (b) still has the problem. Something like

page1.php

<?php
session_start();
$_SESSION['username']='foo!';
?>
<html><head><title></title></head>
<body><a href="page2.php">Click</a></body></html>

page2.php

<?php
session_start();
$username = $_SESSION['username'];
?>
<html><head><title></title></head>
<body><?php echo $username?></body></html>

And if you're getting no joy, see what the value of session_id() is, have a look at the session data file, check that you've got session handling properly enabled in php.ini.

Could it just be a local problem on my machine do you think as when I repeat the session_start() on the second page i get thie error below:

[FONT=courier new]Warning: session_start(): Cannot send session cookie - headers already sent by (output started at /Users/Shared/ceacb/code/page2.php:2) in /Users/Shared/ceacb/code/page2.php on line 3

Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at /Users/Shared/ceacb/code/page2.php:2) in /Users/Shared/ceacb/code/page2.php on line 3[/FONT]

Realised I had an extra bit of white space at the top of page2.php. Deleted that which got rid of the headers error but also did not print anything.....

OK, seems that Safari has some weird session issues but having mangled your code into mine I seem to have something working.....dunno what was happening but it seems fine now...thanks for your help!
