Session Problem

**Hartmann** · Oct 16, 2000 08:09

I am testing out some sessions on my home comp (Win98 with PHP4, MySQL, and Apache) I put in the following code:

Code:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

<html>
<head><title>New User</title></head>
<body>
<?php
session_register ("count");
$count++;
?>

Hello visitor, you have seen this page <? echo $count; ?> times.<p>

<php?
# the <?=SID?> is necessary to preserve the session id
# in the case that the user has disabled cookies
?>

To continue, <A HREF="nextpage.php?<?=SID?>">click here</A>
     

</body>
</html>

And I get this error:
Warning: Cannot send session cookie - headers already sent by (output started at c:\phpdev\www\work\session.php:6) in
c:\phpdev\www\work\session.php on line 7

Warning: Cannot send session cache limiter - headers already sent by (output started at c:\phpdev\www\work\session.php:6)
in c:\phpdev\www\work\session.php on line 7

Warning: open(/tmp/sess_4723d19e4c4f908f32832f38655a32e3, O_RDWR) failed: m (2) in
c:\phpdev\www\work\session.php on line 7
Hello visitor, you have seen this page 1 times.

To continue, click here
Warning: open(/tmp/sess_4723d19e4c4f908f32832f38655a32e3, O_RDWR) failed: m (2) in Unknown on line 0

Warning: Failed to write session data. Please check that the current setting of session.save_path is correct (/tmp) in Unknown
on line 0

I went into the php.ini file and changed the save.path to (sessions)
Any suggestions??
Thanks,

A couple of things: First you need to use
session_start();
to initiate the session Also in the to continue line it should read
To continue, <A HREF="nextpage.php?SID=<? print $SID; ?>">click here</A>

Oh yeah and on the following line
<php?
# the <?=SID?> is necessary to preserve the session id
# in the case that the user has disabled cookies
?>
should be
<?php
# the <?=SID?> is necessary to preserve the session id
# in the case that the user has disabled cookies
?>

<html>
<head><title>New User</title></head>
<body>
<?php
session_register ("count");
$count++;
?>

Hello visitor, you have seen this page <? echo $count; ?> times.<p>

<php?
# the <?=SID?> is necessary to preserve the session id
# in the case that the user has disabled cookies
?>

To continue, <A HREF="nextpage.php?<?=SID?>">click here</A>

</body>
</html>

Ok did all of that.... But I still get this error

Sounds like a problem in your php.ini file. I have never had much luck with PHP4 built-in session management and normally resort to using the PHPLIB for session management. You should have a look at it.

You can use the PHPLib with PHP4?
From this site: http://phplib.netuse.de/
?

The problem is definitely in your php.ini file. You need to set a directory to contain your temporary session files. The setting is clearly marked in php.ini, and is set to "/tmp" by default (which I assume doesn't work on your computer). You should probably set it to something like "C:\WINDOWS\TEMP".
