session wont work

[roomyz]

my session wont work.

i dont know why.

here is the in file1:

session_start();
header("Cache-control: private");
include('fogsheader.php');
ibase_pconnect("path.xxx","GUEST", "123456" );
if (ibase_errmsg()) {
	echo "error: " . ibase_errmsg();
    exit;
}

global $HTTP_SERVER_VARS;

//register session variables
$idnumber = $_POST['idnumber'];
$password = $_POST['password'];

session_register($idnumber);
session_register($password);
session_register($name);
session_register($currentyear);
session_register($currentsem);
session_register($subject);
session_register($section);
session_register($schedule);
session_register($room);
session_register($remarks);

....
?>
i used the registered variables on this page for querying from an interbase database and everythings good.

but on file2:

<?php
session_start();
header("Cache-control: private");
include('fogsheader.php');

session_register($action);
$action = $_POST["action"];

echo "
<div id=\"CenterContent\">
<p>You are logged in as: <strong>$name</strong>. <br>

Idnumber: <strong>$idnumber</strong><br>

Academic Year: <strong>$currentyear</strong> &nbsp;&nbsp;&nbsp;&nbsp;
Semester: <strong>$currentsem</strong><br>
Subject: <strong>$subject - $section</strong><br>
Action: <strong>$action</strong></p>

";

ibase_pconnect("path","GUEST", "123456" );
if (ibase_errmsg()) {
	echo "error: " . ibase_errmsg();
    exit;
}

if ($action=="View Class List") {
	$Q = ibase_query("SELECT * FROM SELECT_ENROLLEES(?,?,?,?)", $subject, $section, $currentyear, $currentsem); 
	echo "<table width=\"100%\">
		<tr>
		<td><strong>Name</strong></td>
		<td><strong>Course</strong></td>
		<td><strong>Idnumber</strong></td>
		<td><strong>Date Enrolled</strong</td>
		</tr>
		<form action=\"http://www.msumain.edu.ph/scripts/fogs/fogsprint.php\" method=\"post\" target=\"_self\"> 	
	";

	$i = 0;
	while ($R = ibase_fetch_row($Q)) {
		$i++;
		echo " 
			<tr>
			<td>$R[1]</td>
			<td valign=\"top\">$R[3] </td>
			<td valign=\"top\">$R[0] </td>
			<td valign=\"top\">$R[4] </td>
		";
	}
	echo "
			</table></form><br>
	";
}
else if ($action=="Enter Grades") {
	$Q = ibase_query("SELECT * FROM SELECT_GRADESHEET(?,?,?,?)", $subject, $section, $currentyear, $currentsem); 
	echo "<table width=\"100%\">

....

?>

how come the session variables dont work no more?
im using php version 4.2.3

the page comes out like:

you are logged on as <BLANK>
academic year <BLANK> semester <BLANK>
damn!!! <BLANK><BLANK><BLANK> nothing is coming out of my queries!

i remember the query working and then the next day it just goes poof! <BLANK>! nothing comes out.

i also tried using $_SESSION['variablename'] for defining session variables but an error comes out. how come??

thanx to anyone who can help out....

session_register($idnumber);
session_register($password);
session_register($name);
session_register($currentyear);
session_register($currentsem);
session_register($subject);
session_register($section);
session_register($schedule);
session_register($room);
session_register($remarks);

Should read

session_register(idnumber);
session_register(password);
session_register(name);
session_register(currentyear);
session_register(currentsem);
session_register(subject);
session_register(section);
session_register(schedule);
session_register(room);
session_register(remarks);

Cheers.

Suggestion: since you've got $POST[] you'll have $SESSION[] as well. That's a lot easier to deal with, 'cos it works like an ordinary array.

Instead of going
session_register('idnumber'); (note: not session_register(idnumber)😉, and then using $idnumber in the script, you can get rid of the session_register() line and just use $_SESSION['idnumber'] the way you would any other variable.

im not sure about something but when i use

$_SESSION['variablename'] i can initialize the variables but i cant seem to echo it properly....

for example:

while(condition) {
echo "
<form action=\"http://www.mypath.php\" method=\"post\" target=\"_self\">
<tr>

<tr>
<td valign=\"top\"> $SESSION['subject'] </td> // this is line 95
<td valign=\"top\"> $SESSION['section'] </td>
// some more code
</tr>
";

the error goes like this:

Parse error: parse error, expecting T_STRING' orT_VARIABLE' or `T_NUM_STRING' in /home/website/mypath.php on line 95

what is wrong here?

i read somewhere that use should use $_SESSION['variablename'] with the single quotes or else some error will happen(i think its in the manual)
