Como colocar o nome do usuário logado no sistema PHP

Question

Bom dia pessoal, sou novo em PHP e gostaria de uma ajuda, estou adapitando um layout no meu painel php e agostaria de colocar o usuário logado nele de acordo com o login que foi utilizado para logar no sistema.

 

Segue abaixo os códigos de validação...

 

<?php error_reporting (E_ALL & ~ E_NOTICE & ~ E_DEPRECATED);require_once('Connections/config.php'); ?>
<?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "") 
{
  if (PHP_VERSION < 6) {
    $theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;
  }

  $theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);

  switch ($theType) {
    case "text":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;    
    case "long":
    case "int":
      $theValue = ($theValue != "") ? intval($theValue) : "NULL";
      break;
    case "double":
      $theValue = ($theValue != "") ? doubleval($theValue) : "NULL";
      break;
    case "date":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;
    case "defined":
      $theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
      break;
  }
  return $theValue;
}
}
?>
<?php
// *** Validate request to login to this site.
if (!isset($_SESSION)) {
  session_start();
}

$loginFormAction = $_SERVER['PHP_SELF'];
if (isset($_GET['accesscheck'])) {
  $_SESSION['PrevUrl'] = $_GET['accesscheck'];
}

if (isset($_POST['Login'])) {
  $loginUsername=$_POST['Login'];
  $password=$_POST['Senha:'];
  $MM_fldUserAuthorization = "";
  $MM_redirectLoginSuccess = "painel.php";
  $MM_redirectLoginFailed = "erro.php";
  $MM_redirecttoReferrer = false;
  mysql_select_db($database_config, $config);
  
  $LoginRS__query=sprintf("SELECT Login, Senha FROM `usuário` WHERE Login=%s AND Senha=%s",
    GetSQLValueString($loginUsername, "text"), GetSQLValueString($password, "text")); 
   
  $LoginRS = mysql_query($LoginRS__query, $config) or die(mysql_error());
  $loginFoundUser = mysql_num_rows($LoginRS);
  if ($loginFoundUser) {
     $loginStrGroup = "";
    
    if (PHP_VERSION >= 5.1) {session_regenerate_id(true);} else {session_regenerate_id();}
    //declare two session variables and assign them
    $_SESSION['MM_Username'] = $loginUsername;
    $_SESSION['MM_UserGroup'] = $loginStrGroup;          

    if (isset($_SESSION['PrevUrl']) && false) {
      $MM_redirectLoginSuccess = $_SESSION['PrevUrl'];    
    }
    header("Location: " . $MM_redirectLoginSuccess );
  }
  else {
    header("Location: ". $MM_redirectLoginFailed );
  }
}
?>

    </tr>
  
</td>
   
    </tr>
  
</table>


    </div>
    </center>

</body>
</html>

 

 

 

E em outra pagina já do painel eu tenho uma área que gostaria de colocar o usuário conforme código abaixo.

 

 <a href="#" class="dropdown-toggle" data-toggle="dropdown">
                          <span class="hidden-xs">          <!--Aparecer o nome do usuário logado??? -->      </span>
            </a>

 

Desde já agradeço a compreenção e ajuda de todos.
