Handling SESSION Vars

ashay

Hi I have a unique Problem

I am setting some session variables which I need to access when I open a POP up window.

I figured that since sessions are not sent to popups we need to explicitely start the SESSION. I did that.

so in pop up, my code looks like this.

if(!isset($_SESSION['user_memberid'])){
	session_start();
	$memb = $_SESSION['user_memberid'];
	echo "Ashay".$memb;
}

Still the $memb variable is not being set.
Does anybody know any way out of this so that I can access my SESSION variables?

The POP is mbeing generated by a third party code called WYSIWYG Pro.

In the popup, after calling session_start(), try doing this:

print_r($_SESSION);

to see what is in the superglobal. If there's nothing in there, it probably means the session ID is not being propagated correctly, and might need to be passed via the URL or something.

The code block you posted runs only if "$_SESSION['user_memberid']" is not set. Inside that block you attempt to assign the unset session value to "$memb", when it's already been determined that there is no value to assign.

If you turn on error_reporting and display_errors then this will be pointed out to you when you run the code.

<?php
// As Drakla reminds:
// This has to be started before any SESSION work/testing
session_start();

// one ! exclamationmark, makes all the difference
// this line reads like:
// if NOT isset SESSION user_memberid
if ( !isset ( $_SESSION ['user_memberid'] ) ) {

$memb = $_SESSION['user_memberid'];
echo "Ashay".$memb;
}

?>

you know what todo now, ashay
dont you?

Drakla

$_SESSION array isn't available until after you use session_start(), so the above will always be true.

yay sumthing i can at least help with im pretty sure your code should look like this.

<?php
session_start();
header('Cache-control: private');
 /* internet explorer 6 fix otherwise sessions can get all screwed up.*/


if(!isset($_SESSION['user_memberid'])){
    $memb = $_SESSION['user_memberid'];
    echo "Ashay".$memb;
}
?>

be aware your saying if $SESSION['user_memberid'] is not set the variable $memb = $SESSION['user_memberid'] which means if its not set your assigning an empty value to $memb its the same as sayin $memb = FALSE;

now if you want $_SESSION['user_memberid'] to be $memb thus registering the session you will use:

$_SESSION['user_memberid'] = $memb

because:
$_SESSION['user_memberid'] = $memb

and

$memb = $_SESSION['user_memberid']

are two different things.

tell me if im wropng i think thats it so if you want to register the session you will use this:

<?php
session_start();

header('Cache-control: private'); //ie6 fix

if(!isset($_SESSION['user_memberid'])){
   $_SESSION['user_memberid'] = $memb
    echo "Ashay".$memb;
}

well i thionk thats it but this also rely's on the fact $memb is set.

bradgrafelman

if(!isset($_SESSION['user_memberid'])){ 
    $memb = $_SESSION['user_memberid'];

Erm, that doesn't make sense at all.

If 'user_memberid' isn't set, why would you assign its value to a variable? It doesn't have a value... it's not set...

<?php 
session_start(); 

header('Cache-control: private'); //ie6 fix 

if(!isset($_SESSION['user_memberid'])){ 
   $_SESSION['user_memberid = $memb 
    echo "Ashay".$memb; 
}

Despite the coding/typing errors, that's probably what was intended.

ownedman

also ALWAYS know when you want sessions in your script if you do it is MUCH EASSIER and correct to put session start up at the top

session_start();
header('Cache-control: private'); // ie6 fix

/* if you want ANY sessions in your page always put this info at the very top of the page. and ill just add how to destroy a session*/

// in order to unregister a single session //use:

if (isset($_SESSION['watevasession'])) {
$_SESSION['watevasession'] = FALSE;
}

/* replace watevasession with the session name */

/* to destroy all sessions that came to the page or have been started on the page use this */

$_SESSION = array();
session_destroy();

// you can add an if statement

if (isset($_SESSION)) {
$_SESSION = array();
session_destroy;
}

that should answer any SESSION questions

Ok Let me rephrase my question again.
The question was not about the code I posted there.
Its about, why my session varibles are not getting set in the POP UP windows. the variable

 $_SESSION['user_memberid']

is set in the parent window. But now when I call the POP UP from the same window, I cannot access the same Session variable, even after doing session_start();
Do any body know how to get ure SESSION Variables in a POP UP window?

[man]session_set_cookie_params[/man] called before session start in BOTH scripts and with a lifetime that's not zero.

halojoy

now a popup window
can be like whatever other php page.
It is a new page.

so it may be that you need to set session_start() first thing in that page.
Is that popup window page called something?
popper.php

in that case, try to put session_start(); in that popper.php
first thing

ashay

in that case, try to put session_start(); in that popper.php
first thing [/B]

Did that already

Drakla

And did you try what I suggested?

like this?

session_set_cookie_params;
session_start();

That is something new to me, halojoy
what does this function do and why we need it?
😕
time to do some study of my own - next time I will know this!!!!!
