Well that's odd, I did a recheck just now, and see that it is how it is done using mysqli. You can check it out on w3schools: https://www.w3schools.com/php/func_mysqli_fetch_row.asp The example there is my reference, I don't know why it doesn't recognize mysqli_fetch_row, have you verified the PHP version and mysqli module?

Replace the line where it says: while($rows = mysqli_query($result)) { With this, I strongly believe this is what you meant to do: while ($rows=mysqli_fetch_row($result)) { It is the explanation for the error message, you wanted to use mysqli_fetch_row(), which requires one argument, but mistakenly type mysqli_query() instead, which, as you have used previously, requires two arguments :) Hth, cmiiw

This the code to it <?php session_start(); /* * To change this license header, choose License Headers in Project Properties. * To change this template file, choose Tools | Templates * and open the template in the editor. */ $username = $_SESSION['username']; include("connect.php"); $result = mysqli_query($conn,"select users.last_name, users.first_name, users.phone, from users where username='$username'"); while($rows = mysqli_query($result)) { $user_fullname = $rows['first_name'].' '.$rows['last_name']; $phone = $rows['phone']; } ?> <html> <body> Welcome <?php echo $_SESSION['username']; ?>, <a href="logout.php">logout</a> </body> </html>
