[Resolved] Session problems I can't figure out...

maxxd

Hi all. Okay, I'm logging in from an index page, passing the $_POST variables to a function that runs a query with the passed vars against a database, then should use the resulting recordset to set session variables. This works, as long as I echo the session vars from the page that calls the function. As soon as I move to another page, despite having called the session_start() function, I get one of two responses. Either the index is undefined or there's nothing there. This is despite the fact that there most certainly is something in each of the 3 set session variables on the previous page. It's just not transferring over. Anybody have any ideas? The verification code is as follows:

function logIn($usr, $pass){
	require("../connections/cnxns.inc");
	mysql_select_db($database);
	$qry="SELECT empID, name, department FROM tblemp LEFT JOIN tbldept ON dept = deptID WHERE empID = '".$usr."' AND pass = '".$pass."';";
	$rs=mysql_query($qry, $cnxn);
	$line=mysql_fetch_assoc($rs);
	$numRows=mysql_num_rows($rs);

if($numRows==1){
	session_start();
	session_register("name");
	session_register("dept");
	session_register("id");
	$HTTP_SESSION_VARS['id'] = $line['empID'];
	$HTTP_SESSION_VARS['name'] = $line['name'];
	$HTTP_SESSION_VARS['dept'] = $line['department'];
	echo $HTTP_SESSION_VARS['id']."<br>";
	echo $HTTP_SESSION_VARS['name']."<br>";
	echo $HTTP_SESSION_VARS['dept'];
//		header("Location: ".$line['department']."Index.php");
	} else {
		header("Location: index.php");
	}
}

I've commented out the header line in leiu of using a text link to move on to the next page - thought maybe, for some odd reason, that line was killing things. It's not the problem. The next page contains the session_start() call, and uses <?php print($HTTP_SESSION_VARS['name']); ?> to try to output the name. I get nothing. Literally. I've used sessions variables succesfully before on this server (no changes or updates - it's my personal testing system - so I know that there's no new settings I should have to deal with). It's just wierd.

Any ideas?

P.S. - the echo calls are there for testing. They work fine on the page that calls this function, but again I get nothing on the next page.

TTT

and you use session_start() on top of the next page??

maxxd

I do. Call it first line.

<?php
	session_start();
?>
<html>
<head>
<title>Company Intranet - <?php print($HTTP_SESSION_VARS['dept']." - ".$HTTP_SESSION_VARS['name']); ?></title>

...

You get the idea. This is causing me no end of trouble, as my title bar reads "Company Intranet - - ". Obviously, I'm trying to use the session vars a bit later down the page to run a query - that's causing larger headaches that the above quoted code, but that chunk was smaller and gives the idea...

[man]session_register[/man] in the man has 2 cautions

1.If you want your script to work regardless of register_globals, you need to instead use the $SESSION array as $SESSION entries are automatically registered. If your script uses session_register(), it will not work in environments where the PHP directive register_globals is disabled.

2.
If you are using $_SESSION (or $HTTP_SESSION_VARS), do not use session_register(), session_is_registered(), and session_unregister().

may I suggest switching to $_SESSION??

I'll give it a shot. Hell, right now, I'd sacrifice a stuffed hamster to the php deities if I honestly thought it would help... However, if I'm not using the sesion_register, should I simply declare and assign the vars at the same time?

$_SESSION['id']=$line['empID'];

Okay - thanks for the hint - I'm off to give it a try.

maxxd

OK. I had tried using just $_SESSION[] already, but I was also registering the session variables, which is apparantly a no-no. Stuffed hamster down, web site up! Thanks ever'body - I was just about out of hair on this one... 😃
