[hallsofvallhalla]

what is the error you are getting?

[herko125]

Notice: Undefined variable: player in C:\wamp\www\battle.php on line 11
thats the error

and second is....that when i try to login with existing usrname and password it says that the username or pw is wrong x.x

[hallsofvallhalla]

Its not saving your session.


after this

Code: Select all

if (isset($_SESSION['player']))
{
$player=$_SESSION['player'];
}

add this

Code: Select all

else
{
echo "You are not logged in. <a href='login.php'>Login";
exit;
}

there is something screwy with the username and password fields in the first videos, post your register and your reguser.php code...

[herko125]

okay

register.php

Code: Select all

<?php
include 'connect.php';

?>

<form method="post" action="reguser.php">
Type Username Here: <input type="text" name="player" size="21"><br>
Type Password Here: <input type="password" name="password" size="15"><br>
Retype password:  <input type="password" name="pass2" size="15"><br>
Type E-mail address: <input type="text" name="email" size="60"><br>
<input type="submit" value="submit">
</form>

reguser.php

Code: Select all

<?php
include 'connect.php';
?>

<?php
$player=$_POST['player'];
$password=$_POST['password'];
$pass2=$_POST['pass2'];
$player=strip_tags($player);
$email=$_POST['email'];
$email=strip_tags($email);

if ($email == "")
{
echo "You didn't enter a email address!<br>";
echo " <A href='register.php'>Go back</a>";
    exit;
    }
if ($password==$pass2)
{
 
  $isplayer="SELECT * from players where name='$player'";
  $isplayer2=mysql_query($isplayer) or die("Could not query players table");
  $isplayer3=mysql_fetch_array($isplayer2);
  if(!$_POST['password'] || !$_POST['pass2'])
  {
     print "You did not enter a password";
    echo " <A href='register.php'>Go back</a><br>";
    exit;
  }
  else if($isplayer3 || strlen($player)>15 || strlen($player)<1)
  {
     print "There is already a player of that name or the name you specified is over 16 letters or less than 1 letter<br>";
     echo " <A href='register.php'>Go back</a>";
    exit;
  }
  else
  {
    $isaddress="SELECT * from players where email='$email'";
    $isaddress2=mysql_query($isaddress) or die("not able to query for password");
    $isaddress3=mysql_fetch_array($isaddress2);
    if($isaddress3)
    {
      print "There is already a player with that e-mail address<br>";
      echo " <A href='register.php'>Go back</a>";
    exit;
    }
    else
    {
        $password=md5($password);
       
$SQL = "INSERT into players(name, password, email, level, exper) VALUES ('$player','$password','$email','1','0')";
      mysql_query($SQL) or die("could not register");
     
      print "Thank you for registering.";
   
    }
  }
}

else
{
  print "Your password didn't match or you did not enter a password<br>";
   echo " <A href='register.php'>Go back</a>";
    exit;
}
echo "<br><A href='login.php'>Login Page</a>";
?>

login.php (just incase)

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">
<input type="submit" value="Login" name="submit">

[hallsofvallhalla]

lets see the authenticate.php too.

[herko125]

okay

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' ";
   $result = mysql_query($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>";
}
}
?>

[hallsofvallhalla]

change this

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' ";

[herko125]

*edit*

so now when i login with an account named testing and I attack the creature....
the testing dont fight with Goblin...but player1 dose...
even if im not logged in with it...

Code: Select all

$playerinfo="SELECT * from players where name='player1'";

to

Code: Select all

$playerinfo="SELECT * from players where name='$players'";

Notice: Undefined variable: players in C:\wamp\www\attack.php on line 7
