that just means you submit button is not working. Check your login code and see why.

ah should I have a submit button on login i just have to press enter because there isn't one

[OldRod]

Looking back at the code you posted on an earlier page for your login screen:

Code: Select all

<form method="POST" action="authenticate.php">
UserName <input type="text" name="player" size="21"<----------- add > here
Password <input type="password" name="password" size="21" mask="x">
<br>
<input type="submit" value="login" name="submit"<-------------add ></form> here

You're missing a ">" at the end after "submit" and you also need a </form> tag closing

  $query = "select name,password from players where name='$player' and '$password'";
  $result = mysql_query($query) or die("Could not query players");
  $result2 = mysql_fetch_array($result);
  if ($result2)
  (
  $_SESSION['player']=$player;
  
  echo "<big>Logged in succesfully<br>";
  echo "<A href='battle.php'>Continue</a></big>";

couple issues
you have ( and ) instead of { and } on your if and else statements

Code: Select all

if (isset($_POST['submit']))
(
$player=$_POST['player'];

should be

Code: Select all

if (isset($_POST['submit']))
{
$player=$_POST['player'];

and this

Code: Select all

$query = "select name,password from players where name='$player' and '$password'";

should be

Code: Select all

$query = "select name,password from players where name='$player' and password='$password'";

Either of those are likely the problem. When structuring issues occur such as swapping "( )" for "{ }", you will oftentimes get "parse errors". This usually means the interpreter is completely messed up and has no idea what you are doing. A simple mistake trips it, and it just keep tripping.

how can i make a racing game using php?

If you follow along with the tutorials, everything you would need to make a racing management game is there. You just have to be creative. If you are interested in making an online game where you control the cars, and actually steer them, that cannot be done with PHP. PHP is a server-side scripting language, so it can only update the player when the screen refreshes. Maybe something like that could be done with AJAX, but I would suggest against making it multiplayer, because the calculations would have to be done on the browser-side, which could easily be hacked.
