you could actually just watch the videos up to about 14 or so then I started putting code back in for download.

You will get a lot less errors and understand it better if you do it that way. Although I still suggest supplementing it with the book I linked a few posts back!

Well i'm doing it along with the videos and checking in with that book. I'm not doing exactly what the videos say I've already watched all the videos (1-20) now i'm going back and doing them and substituting in what i want for the game I'm makeing and toying around with other code. Now that the videos are getting less and less. . . idk how to put it, necessary? You know they don't have to be a certain way or else the whole game wont work.

You should make the whole tutorial game verbatim and then edit it from there. That way you have a working game structure to build on. Substituting new parts as a beginner while you are laying the groundwork is a recipe for problems.

Hey, HallsofVallhalla i got a problem at authenticate.php at line 7 heres the code of authenticate.php:

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='battle.php'>Continue</a></big>";
  }
  else
  {
   echo "<big>Wrong username or password.<A href='login.php'>Try Again</a></big>";
  }
}
?>

Code: Select all

its not finding the post variable 'player', so you need to go to login.php and see if it is different when it sends it. feel free to post your login.php if you cant find it.

My english is very bad.. but heres the login.php

Code: Select all

<form method="POST" action="authenticate.php">
User Name <input type="text" name=player" size="21">
Password <input type="password" name="password" size="21" mask="x">
<br>
<input type="submit" value="Login" name="submit">

Heheh i don't know if this is outdated to write here, but i have been recently doing these tuts ~ and stumpled across a problem. I've looked this thread over, but dont seem to find the answer.

alot of people get the solution ~

Code: Select all

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

to

Code: Select all

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