    hi,
    I want to try and make it so that when someone is not logged in, it shows a "login" button on my main page, but if they are logged in, if doesn't show the login button.
    so I was just wondering how amember knows when you are logged in, so that I can make my page know when you are logged in, to display the login button or not. (I know enough php to make it display the button, but anything harder than that, and you may need to explain ;))
    Thanks

    It's easy:

    PHP:
    <?php
    session_start    ()
    if (    $l=$_SESSION['_amember_login']){
          $u = $_SESSION['_amember_user'];
      print     "Hello $u[name_f] $u[name_l]!<br>";
    } else {
      print     "<form method=post action='/amember/login.php'>
     Login: <input type=text name=amember_login><br>
     Password: <input type=password name=amember_pass><br>
      <input type=submit value=Login>
    </form>"    ;
    }

    ?>

    When I first tried this code snippet, I received the following error message:

    Code:
    Warning: Cannot send session cache limiter - headers already sent
    I solved the problem by moving the following line to the very start of my PHP file, before the <html> tag:

    Code:
    <?php session_start() ?>
    And then the remaining code, which now works fine, becomes:

    Code:
    <?php
if ($l=$_SESSION['_amember_login']){
  $u = $_SESSION['_amember_user'];
  print "Hello $u[name_f] $u[name_l]!<br>";
} else {
  print "<form method=post action='/amember/login.php'>
Login: <input type=text name=amember_login><br>
Password: <input type=password name=amember_pass><br>
  <input type=submit value=Login>
</form>";
}
