Daha spesifik Ben $last_name tüm görüntülemek için alınamıyor.

Aşağıdaki kodu:

$name_and_date = "$first_name $last_name | $today | <a href=\"logout.php\">Log out</a>";

İşte kod fazla.

// Place Session variables into local variables
$user_id = $_SESSION['user_id'];
$first_name = $_SESSION['first_name'];
$last_name = $_SESSION['last_name'];
$email = $_SESSION['email'];
$registration_date = $_SESSION['registration_date'];
// Convert the sign up date to be more readable by humans
$registration_date = strftime("%b %d, %Y", strtotime($registration_date));
// Use PHP to find today date and get it ready for display
$today = date("F j, Y");
$name_and_date = "$first_name $last_name | $today | <a href=\"logout.php\">Log out</a>";
require_once ('../mysqli_connect.php'); // Connect to the db.
// Query member data from the database and ready it for display
	$mysqli = new mysqli("localhost", "root", "", "sitename");
	$dbc = mysqli_query($mysqli,"SELECT * FROM users WHERE user_id='$user_id'");
if (!$dbc) {
	// There was an error...do something about it here...
	print mysqli_error();
}  else {
	while($row = mysqli_fetch_array($dbc)){ 
		$city = $row["city"];
		$zip = $row["zip"]; 
		$bio_body = $row["bio_body"];
        $last_name = $row["last_name"];
	}
}
