I will have to review the code in a little bit for the error but here is video 14. It was on the second page.

Alright, thanks. Just post it once you are done. Thank you so much.

Post by **hallsofvallhalla** » Wed Aug 25, 2010 1:34 am

then change this line

Code: Select all

$width = ($playerinfo3['hpoints'] / $playerinfo3['maxhp']) * 100;

hey halls i have a problem, whenever i create my username and password and email, it says you are now registered, but when i go to login it says the username or password you entered is incorrect, what am i doing wrong? i think its something wrong with my authenticate page. please take a look.

Code: Select all

<?php
include_once 'connect.php';
session_start();

if (isset($_POST['submit']))
{
  $player=$_POST['player'];
  $password=$_POST['password'];
  $player=strip_tags($player);
  $password=strip_tags($password);
  $password=md5($password);

  $query = "select name,password from players where name='$player' and password='$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 successfully<br>";
    echo "<A href='index.php'>Continue</a></big>";
  }
  else
  {
   echo "<big>Wrong username or password.<A href='login.php'>Try Again</a></big>";
  }
}
?>
