這是我的登錄頁面。我從這裏得到什麼代碼或查詢並添加到我想要顯示用戶名的位置，以顯示用戶全名？如何從數據庫中獲取用戶的名稱，並在用戶登錄時將其顯示給用戶？
<?php
define('DB_HOST', 'localhost');
define('DB_NAME', 'university portal');
define('DB_USER','root');
define('DB_PASSWORD','password007');
$con=mysql_connect(DB_HOST,DB_USER,DB_PASSWORD) or die("Failed to connect to MySQL: " . mysql_error());
$db=mysql_select_db(DB_NAME,$con) or die("Failed to connect to MySQL: " . mysql_error());
/*
$ID = $_POST['user'];
$Password = $_POST['pass'];
*/
function SignIn()
{
session_start(); //starting the session for user profile page
if(!empty($_POST['UserName'])) //checking the 'user' name which is from Sign-In.html, is it empty or have some text
{
$query = mysql_query("SELECT Username, Password, voting_status FROM voters where Username = '$_POST[UserName]' AND Password = '$_POST[password]'") or die(mysql_error());
$row = mysql_fetch_array($query) or die(mysql_error());
if(!empty($row['Username']) AND !empty($row['Password']))
{
$_SESSION['Username'] = $row['Password'];
$_SESSION['Voting Status'] = $row['voting_status'];
header("location:Voters Account.php");
}
else{
echo "username or password is incorrect";
}
}
}
if(isset($_POST['submit']))
{
SignIn();
}
?>
這是我要顯示用戶全名的地方，所以請我真的需要幫助，謝謝。在[用戶名]的行
