I think you should use the post method for the form and then store the values in the sessions but remember to start session first Here you logged in

<php? 
  // Check to see if we have some POST data, if we do process it
  if ( isset($_POST['name']) && isset($_POST['pass']) ) {
    $_SESSION["name"] = htmlentities($_POST["email"]);
     header( 'Location: view.php' ) ;
     return;
  }
?>


<form action="handleLogin.php" method="post">
  <div class="user-box">
    <input type="text" name="loginEmail" required="">
    <label>Email</label>
  </div>
  <div class="user-box">
    <input type="password" pass="loginPass" required="">
    <label>Password</label>
  </div>
  <input type="submit" value="LogIn" name="submit">
</form>

Did you actually defined $_SESSION['username'] = 'some username or database value'; any where at your back-end program? You should share that too if the problem has not been resolved!
