Help with $_SESSION

broann

Pardon my ignorance, I've been searching for answers for this new $SESSION to work to no avail. If someone can help me out by giving examples how I can pass the session_id to the next page and access the same $SESSION["var"] on that page, it would be very helpful.

My question is, once I set this on the 1st page:
<?
session_start();
if (!isset($SESSION["foo"])) {
$SESSION["foo"] = "test foo";
}

?>
<body>
<? echo $_SESSION["foo"] . " ";
echo session_id() . " ";

echo " ";
?>
<a href="reg_2.php?id="<? session_id(); ?>">reg_2.php</a>
</body>

How do I set up link to the next page, and what should I put on the next page? Will this be correct?

<?
session_id($GET["PHPSESSID"]);
session_start();
?>
<body>
<? print $SESSION["foo"]." "; ?>
</body>

But I got this error message:

Warning: Undefined index: foo in c:\phps\reg_2.php on line 6

I'm new to PHP so this is also a major factor of the failure. Again, thanks for your help.

Use of $SESSION (or $HTTP_SESSION_VARS with PHP 4.0.6 or less) is recommended for security and code readablity. With $SESSION or $HTTP_SESSION_VARS, there is no need to use session_register()/session_unregister()/session_is_registered() functions. Users can access session variable like a normal variable.

Should work,
but... first, you need to lose this:
session_id($_GET["PHPSESSID"]);
..that just does't seem right,
and the session_start() will handle that for you anyway.

Hi
I use session ids a lot. What I do is
session_sart();
at the begging of every page that you want variables to be used in
then register the variables ie
session_register ( "variablename" ):
in the section you have declared that variable. Do not use the $ sign when using session_register only the variablename:
example
session_start();
session_register( "name" );
$name=$form[name];

Make sure you you session_start on the next page that way the variable $name will be carried over.
Hope this helps

I just read in the manual that if I use $_SESSION I don't need to use session_register(), isn't this going to be deprecated? But somehow I couldn't think any other way to make it work.

I tried it and somehow it still didn't work, is there anything that I should change in php.ini probably? BTW, I'm running PHP on Win2K if that would make anything different.

I found my way more reliable. And definitely keeps track of of the user if that's the case
