getting session to pass to another page

[kilbey1]

I have sessions stored to a database fine; but it won't pass to another page. What could be wrong here?

Start page session code:

	require "include/db_control.php";
	require "include/html_templates.php";
	require "include/form_controls.php";
	require "include/SQLutilities.php";
	HTMLhead("Welcome To SMCP Review", "include/defaultStyle.css", FALSE);


OpenMySQL();
function mysql_table_exists($table, $link)
{
     $exists = mysql_query("SELECT 1 FROM `$table` LIMIT 0", $link);
      if ($exists) return true;
     return false;
}

if(!mysql_table_exists("sessions",$DB))
{
       $query = 'CREATE TABLE sessions
                 (
                  SessionID     char(255)   not null,
                  LastUpdated   datetime    not null,
                  DataValue     text,
                  PRIMARY KEY ( SessionID ),
                  INDEX ( LastUpdated )
                 )';
       mysql_query($query);
}


function sessao_open($aSavaPath, $aSessionName)
{
       global $aTime;

   sessao_gc( $aTime );
   return True;
}

function sessao_close()
{
       return True;
}

function sessao_read( $aKey )
{
       $query = "SELECT DataValue FROM sessions WHERE SessionID='$aKey'";
       $busca = mysql_query($query);
       if(mysql_num_rows($busca) == 1)
       {
             $r = mysql_fetch_array($busca);
             return $r['DataValue'];
       } ELSE {
             $query = "INSERT INTO sessions (SessionID, LastUpdated, DataValue)
                       VALUES ('$aKey', NOW(), '')";
             mysql_query($query);
             return "";
       }
}

function sessao_write( $aKey, $aVal )
{
       $aVal = addslashes( $aVal );
       $query = "UPDATE sessions SET DataValue = '$aVal', LastUpdated = NOW() WHERE SessionID = '$aKey'";
       mysql_query($query);
       return True;
}

function sessao_destroy( $aKey )
{
       $query = "DELETE FROM sessions WHERE SessionID = '$aKey'";
       mysql_query($query);
       return True;
}

function sessao_gc( $aMaxLifeTime )
{
       $query = "DELETE FROM sessions WHERE UNIX_TIMESTAMP(NOW()) - UNIX_TIMESTAMP(LastUpdated) > $aMaxLifeTime";
       mysql_query($query);
       return True;
}

session_set_save_handler("sessao_open", "sessao_close", "sessao_read", "sessao_write", "sessao_destroy", "sessao_gc"); 

session_start();
header("Cache-control: private"); 
// Get the user's input from the form 
   			$username = $_POST['username']; 

		// Register session key with the value 
		$_SESSION['username'] = $username; 

?>

Debug code on another page always shows up "Ok, the session is no longer registered! "

ession_start();
header("Cache-control: private"); //IE 6 Fix 


if (isset($_SESSION['username'])) {
       echo "The session is still registered.<br /><br />"; 
} else { 
       echo "Ok, the session is no longer registered! <br />"; 
} 

Current PHP.INI file session settings:

[Session]
session.save_handler = files
session.save_path = C:\services\php\sessiondata ; argument passed to save_handler

session.use_cookies = 1
; session.use_only_cookies = 1

session.name = PHPSESSID

session.auto_start = 0

session.cookie_lifetime = 0

session.cookie_path = /

session.cookie_domain =

session.serialize_handler = php

session.gc_probability = 100
session.gc_dividend = 100

session.gc_maxlifetime = 1440

session.bug_compat_42 = 1
session.bug_compat_warn = 1

session.referer_check =

session.entropy_length = 0

session.entropy_file =

;session.entropy_length = 16

;session.entropy_file = /dev/urandom

session.cache_limiter = nocache

session.cache_expire = 180

session.use_trans_sid = 0

Database results thus far:

Here's an addition to this.

Throw these items into a .php file; one spits out a cookie and shows a count, start, and how long it lasts.
The second part points to a session, gives the session id, count, start and how long it lasts.

My result on session is always 0!

Here's the code.

<?php

 // Register the variable named "foo"
session_register("foo");
$foo = "bar";

// See if the HTTP request has set $count as the 
// result of a Cookie called "count"
if(!isset($count)) {
  // No cookie called count, set the counter to zero  

  $count = 0;

  // .. and set a cookie with the "start" time
  // of this stateful interaction
  $start = time(  );
  setcookie("start", $start, time(  )+600, "/", "", 0);

} else {
    $count++;
}

// Set a cookie "count" with the current value
setcookie("count", $count, time(  )+600, "/", "", 0);

?>
