Ok, this is my script. Obviously, look at the fields and modify them.

 

Login:

//put this before your opening html tags
<?php
ob_start();
session_start();
include 'dbs.php';



if (isset($_POST['username']) && isset($_POST['password']))
{
    //if the user has just tried to log in
    $username = $_POST['username'];
    $password = $_POST['password'];
    
    
    $query= 'select * from users '
            ."where username='$username' "
            ."and password=md5('$password')";
    $result = mysql_query($query);

    if (mysql_num_rows($result) > 0)
    {
        //if they are in the db, register the user id

        $_SESSION['user'] = $username;


$userr = mysql_query("SELECT * FROM users WHERE username = '$username'");
  $row = mysql_fetch_assoc($userr);
        $_SESSION['lvl'] = intval($row['level']);
$_SESSION['userID'] = intval($row['ID']);


$id = $_SESSION['userID'];

$lin = "UPDATE users SET llin = NOW() WHERE ID = '$id' ";
mysql_query($lin) or die('Error, query failed now');
$liyn = "UPDATE users SET active = '1' WHERE ID = '$id' ";
mysql_query($liyn) or die('Error, query failed');





    }
}

?>

// Put this stuff in the middle of your page.
<font face="Verdana, Helvetica, Trebuchet MS, Comic Sans MS, Arial">
<?php
  if (isset($_SESSION['user']))
  {
    //logged in OK
    echo '<br>Welcome back, '.$_SESSION['user'].'!'.' Redirecting in 5 seconds or <a href="index.php">continue</a>.';
?>
<meta http-equiv="REFRESH" content="5;url=index.php">
<?php
  }
  else
   {
       if (isset($username))
       {
           //they tried to log in and failed
           echo '<font color="grey"><i>Login failed. Please try again.</i></font><br><br>';
       }
       else
       {
           //they have not tried to log in or have not yet logged out
           echo 'If you already have a user name and password, please login below. <br /><br>';
       }
    //provide a form to log in
    echo '<form method="post" action="login.php">';
    echo '<table>';
    echo '<tr><td>User Name:</td>';
    echo '<td><input type="text" name="username"></td></tr>';
    echo '<tr><td>Password:</td>';
    echo '<td><input type="password" name="password"></td></tr>';
    echo '<tr><td colspan="2" align="center">';
    echo '<input type="submit" value="Log in"></td></tr>';
    echo '</table></form>';
echo '<font size="-3">Not registered? Register <a href="register.php">here</a>.</font>';
  }
ob_end_flush();
?>
</font>

 

Register:

<font face="Verdana, Helvetica, Trebuchet MS, Comic Sans MS, Arial">
<form  method="post" action="reging.php">
WARNING! You MUST type in a valid Email address otherwise you will not be able to make changes to your account.
<hr>
Type Username: 
<input type="text" name="u1">
<br>
Retype Username: 
<input type="text" name="u2">
<br>
<br>
Type Password: 
<input type="password" name="p1">
<br>
Retype Password: 
<input type="password" name="p2">
<br>
<br>

Retype Email: 
<input type="text" name="e2">
<br>
<br>
<input type="submit" value="Submit"><input type="reset" value="Reset">
</form>









</font>

 

reging.php:

<?php



include 'dbs.php';


if ($_POST['u1'] == $_POST['u2'] && $_POST['e1'] == $_POST['e2'] && $_POST['p1'] == $_POST['p2']) { 

if ($_POST['u1'] == ''){
echo "No.";
exit;
}

if ($_POST['e1'] == ''){
echo "No.";
exit;
}

if ($_POST['p1'] == ''){
echo "No.";
exit;
}


$sql = "select * from users where username='" . $_POST['u1'] . "'"; 
$result = mysql_query($sql); 


$sql2 = "select * from users where email='" . $_POST['e1'] . "'"; 
$result2 = mysql_query($sql2); 

if (mysql_num_rows($result) >= 1) { 
$err =  "Username, ";
}else{
$err =  "";
}

if (mysql_num_rows($result2) >= 1) { 
$err2 =  "Email ";
} else {
$err2 = "";
}



if (mysql_num_rows($result) >= 1 || mysql_num_rows($result2) >= 1) { 

echo '<b>Error: </b>'; echo $err; echo $err2; echo 'already in use - <a href="register.php">try again</a>.';
} else { 
$username = $_POST['u1']; 
$pass = md5($_POST['p1']); 
$email = $_POST['e1']; 


$usernamee = htmlentities($username);
$emaile =  htmlentities($email);


$sql = "INSERT INTO users (ID, username, password, email, level) VALUES (NULL, '$usernamee', '$pass', '$emaile', '10')";
mysql_query($sql) or die('Registration failed'); ?>
<meta http-equiv="REFRESH" content="0;url=pregister.php">

<?php
}
}else{
echo '<b>Error:</b> You filled the form in incorrectly - <a href="register.php">try again</a>.';
}
?>

 

then for a protected page:

if(!isset($_SESSION['user']))
{
?>
  You have to login/register this page. Return to the <a href="forum.php">General Board List</a> to select a board.
  <?php

exit;
}
// put protected page here
?>

 

 

Okay, thats quick. If some stuff doesn't link up, tell me, ill fix it. Where it includes dbs.php, thats your database connection page

 

Any problems, questions, let me know.

}

else {

$kt = split(' ', $levels);

 

$query = mysql_query('SELECT Level_access FROM users WHERE ID = "'.mysql_real_escape_string($_SESSION['user_id']).'"');

$row = mysql_fetch_assoc($query);

 

$access = FALSE;

 

while(list($key,$val)=each($kt))

{

if($val==$row['Level_access'])

{//if the user level matches one of the allowed levels

$access = TRUE;
