I create the session variable $_SESSION within my validateLogin.php file shown here:

<?php
    include'db_config.inc';
    require_once('InitDB.php');
    
    $error_msg = '';
    $error_flag = false;
    
    function clean($str) {
	$str = @trim($str);
	
        if(get_magic_quotes_gpc()) {
	    $str = stripslashes($str);
	}
	
        return mysql_real_escape_string($str);
    }
    
    try {
        $dbh = new PDO("mysql:host=127.0.0.1;dbname=$db", $user, $password);
    }
    catch (PDOException $e) {
        die($e->getMessage());
    }
    
    $username = clean($_POST['username']);
    $password = clean($_POST['password']);
    
    if((!isset($username))or(!isset($password))){
        $error_msg = 'Missing Value or Values';
        $error_flag = true;
    }
    
    if($error_flag){
        $_SESSION['ERR_MSG'] = $error_msg;
        session_write_close();
	header("location: login.html");
	exit();
    }
    
    $loginmatches = $dbh->query ("SELECT * FROM Member WHERE username = '$username'
                                  AND password = '$password'");
    
    if($loginmatches){
        if($loginmatches->rowCount() == 1){
            $member = $loginmatches->fetch(PDO::FETCH_ASSOC);
	    
	    $dbh->exec ("INSERT INTO `Login` 
			(`username`,`loginTime`)
			VALUES ('$username',NOW())");
	    
	   [B] $_SESSION['SESS_MEM_ID'] = $member['username'];
	    
	    switch($member['siteRole']){
		case "MEMBER":
		    header("location: member_profile.php");[/B]
	    }
        }
	else {
	    header("location: login.php");
	}
    }
    else{
	$error_msg = 'Incorrect value or values entered!';
	$_SESSION['ERR_MSG'] = $error_msg;
	session_write_close();
	header("location: login.php");
    }
    
    echo $member['username'];
    
    
?>

I have highlighted in bold where the variable is created and forwarded to the member profile page. This is my member profile page code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <title>Member Login</title>
    <link rel="stylesheet" type="text/css" media="screen" href="login.css" />
    </head>
    <body>
        <div id = "whole">
            <div id = "mainHeading">
                <h1>Taxi Service</h1>
            </div>
            <div id = "links">
            </div>
            <div id = "content">
                Welcome <?php echo $_SESSION['SESS_MEM_ID']; ?>
            </div>
            <div id = "footer">
            </div>
        </div>
    </body>
</html>

Where the username should be printed out within the php tags, i receive the following error:

Notice: Undefined variable: _SESSION in C:\Program Files\EasyPHP-5.3.8.1\www\Final Year Project\member_profile.php on line 16

Once i find out why the variable isn't passing, i'd like to use the sessions to display error messages if a login fails also.

Any help would be appreciated.

Thanks.

hmm. DO you have session_start() at the top of all files that use $_SESSION?

Member Avatar for BenzZz

I tried that before and still got the message saying that the index SESS_MEM_ID was undefined.

Member Avatar for BenzZz

anyone?

Member Avatar for diafol

It's just that I don't see a session_start in the profiles page.

Member Avatar for BenzZz

I inserted the session_start at the top of the page:

<?php
    session_start();
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <title>Member Login</title>
    <link rel="stylesheet" type="text/css" media="screen" href="login.css" />
    </head>
    <body>
        <div id = "whole">
            <div id = "mainHeading">
                <h1>Taxi Service</h1>
            </div>
            <div id = "links">
            </div>
            <div id = "content">
                Welcome <?php echo $_SESSION['SESS_MEM_ID']; ?>
            </div>
            <div id = "footer">
            </div>
        </div>
    </body>
</html>

and still getting this output:

Welcome
Notice: Undefined index: SESS_MEM_ID in C:\Program Files\EasyPHP-5.3.8.1\www\Final Year Project\member_profile.php on line 19
