Sessions. Very simple question ... please help.

[chunk]

I can't get sessions to work. Ive reduced what i'm trying to do down to the most simple level:

 

page1.php

 

<?php

session_start();

$_SESSION['username'] = "UserOne";

echo $_SESSION['username'];

echo "<br><a href='page2.php'>Go to another page</a>";

?>

 

page2.php

 

<?php

session_start();

echo $_SESSION['username'];

?>

 

All that ever happens is that you click on the link to page 2 (from page 1) and you get a blank page.

 

No matter what I do, I cant access the session variable in page 2, that I can on page 1.

 

Can anyone help? Thanks.

Have you check if session are enabled?

Have you check if session are enabled?

 

 

Ive tried to read through documentation and as far as I can tell, yes they are. Could you help me to check please?

Is that really all that's on page2? If there is still more code, a blank page could mean you have a fatal error, but don't have error reporting on.

create a file on your sever called phpinfo.php

copy and paste this in:

<?php

phpinfo();

?>

 

and access this page, I can take a look if you give the link

That is all thats on page two. Like I said, ive reduced it right down to the bare minimum so that all other causes of a problem can be ruled out.

sessions don't last between subdomains - are you going from www.domain.com to domain.com (no www?)

try placing print_r($_SESSION); on both pages?

[hvle]

Somebody has the same problem before.

He said if he commented out the session.save_path from php.ini, it works.

 

change

session.save_path to

;session.save_path

 

in your php.ini

Not going between subdomains no.

 

print_r($_SESSION) on page 1 gives me: ( [username] => UserOne )

print_r($_SESSION) on page 2 gives me: Array ( )

change

session.save_path to

;session.save_path

 

in your php.ini

 

Tried it. Makes no difference.

[Jessica]

What version of PHP is this?

[hvle]

ok,

 

now try change your session.save_path to a valid writeable directory.  Do not comment it out.

Got it to work. I commented it out, but forgot to restart my web server.

 

Commenting it out and restarting made it work.

 

Thanks very much!

 

Can I ask, is it a good idea to just comment it out or is it better to change it to something that is valid.

[hvle]

it is better to point to a valid directory.

if you commented it out, it would use cookie to store session data.

and personally, I think it is not safe to use cookie to store session data at all.

[Jessica]

Yeah you need a valid dir.

Users can easily edit cookie data, and if they have cookies blocked, your sessions won't work.

[chunk]

Ok, thanks. So what would make a good valid dir? Something in my apache web server folder where my php files are?

[hvle]

any local directory would do fine, it's your call
