Basically i've been looking for a code to put into the index page. Where let's say your new, and you see a text that says

welcome visitor and then you login, and once you are it should say Hello .'user'.

I've looked around, but no one seems to know. One came up, although it's from wordpress, and well i put it on my code, but i believe there something missing that i don't have. I just need a simple code, please you have one let me know

please explain the code and what I should change, cause sometimes i change things I shouldn't change and make things more complicated.

<?php include_once("header_bottom.php"); ?>

</html>

I put it back to my own code, because I kind of got confused on where to put it. I put it on the top for both and it showed up although the welcome guest shows up all the way to the top. The code on the bottom is where i want the text to be.

              <?php
?>
            <p align="left">Hello <strong><?=$_SESSION['username']?></strong> , are you already signed up? <a href="logout.php">Logout</a> and log back in. Maybe your wanting to <a href="registro.php">Signup</a>?</p>
            <p>
              <?php
        }
    ?>  
            </p></div></td>
                    </tr>
                  </table>
                  </div></td>
              </tr>
            </table>

    So let's assume user logs in, and correct credentials are set.

    So we set a session with the username (in this case Script47). So something like this.

    // Blah blah above user logs in...
    // $username is the value of the login form. You have now set SESSION "username" to that value
    session_start();
    $_SESSION['username'] = $username;
    

    There after, when on a "main" page (the page after login) have this.

    session_start();
    
    if(!isset($_SESSION['username']) || empty($_SESSION['username'])) {
        echo 'Welcome Guest.'; // Your message here.
    } else {
        echo 'Welcome ' . $_SESSION['username'];
    }
    

    Don't forget to start session when setting session.
