session not saved

[zang8027]

on my site, i am setting 2 sessions. Now, if you log in, it sets a session called 'priv'. If you click buy, it takes you to paypal, you go through that, and then once the order is complete, paypal uses a instant notfication to send certain values back to whatever page i tell it to.

 

So, assuming you logged in, and the session was set, this should be registered right?:

 

 

<?php
session_start();


//We need to first grab the information being passed
$date = $_REQUEST['payment_date'];
$cost = $_REQUEST['mc_gross'];
$restaurant = $_SESSION['rest'];
$user = $_SESSION['priv'];

if(session_is_registered('priv')){

	$myFile = "./payments.log";
	$fh = fopen($myFile, 'a') or die("Cannot Connect to Log");

	$v = "$user was set \n";

	fwrite($fh, $v);
	fclose($fh);
}else{
	$myFile = "./payments.log";
	$fh = fopen($myFile, 'a') or die("Cannot Connect to Log");

	$v = "$user $restaurant No session registered \n";

	fwrite($fh, $v);
	fclose($fh);

}

 

 

It doesn't. I can echo out the session and get the proper value but when paypal sends back to this page (which is never opened, so the user never sees this page.. its all behind the scenes), the session is no longer set.

 

 

Im stumped... any ideas on how I can save the session data? I would write it to a file BUT there could be multiple orders going on at once so the session that I write to a .txt file would be over written.

 

 

 

The end goal is to grab the order information that paypal is sending back, connecting to a database, and add the stuff to a table where userID = {$_SESSION['priv']};

I had very similar issues when I had one web-page embedded inside another using the <OBJECT> tag.

 

Bizarrely, the session variable was kept in Firefox but not IE,  this was utterly WEIRD since PHP, as you probably already know is run on the SERVER - and therefore the browser should not have made a scrap of difference.  But it did !!!!!!

 

I tore my hair out over it and lost quite a bit of sleep that night trying to fix it.

 

The alarm bells rang a bit for me when you said "this goes on behind the scenes" which is similar to what I was trying to do.  The only answer in the end was to NOT do it behind the scenes and to figure out another way of doing it.

 

Also, the bouncing back to and fro from paypal may be re-setting your session variables.  One alternative is to try saving the info in a browser-side cookie.  Another is to quickly poke the variable into a mysql database and then dig it out again later.  But be warned - IE8 does weird unexpected things with this technique as I found to my intense frustration.

session_is_registered has long been depricated. I would use....

 

if (isset($_SESSION['priv']) {

 

and see if your issue persists.

You forgot a parenthesis

if (isset($_SESSION['priv'])) {

<?php
session_start();
if(isset($_SESSION['priv'])){
     echo 'im set!';
}else{
     echo 'im not set';
}
?>
