Look, Brent. You say your code doesn't work, but you don't show it. Someone suggests you show it, and you do, but you don't point out the areas that don't meet your expectations, or the errors you're getting, or anything. You need to help people help you by providing all the information available. Information is what debugging is all about. As it is, we have to examine your code from top to bottom instead of concentrating on one particular section. Of course, we'll do that, but give us a break, huh?

Right off the top of my head, before I look in detail, I see your function name is invalid.

EDIT: Oops, your form action in incorrect, also. The action specifies what server page to request (normally a script), it doesn't specify a function name. Let me ask a question: are you aware of the client/server nature of the interaction and exactly what that means in terms of what code is run where?

EDIT 2: You're overlapping your form and table elements in non-compliant ways.

This is how i would do it.

[PHP]
<html>
<head>
<title>Login:</title>
</head>
<body>
<?PHP
switch ($_POST['action'])
{
case "Login":
$username=$_POST['username'];
$password=$_POST['password'];
if($username=='webmaster' && $password=='pass')
{
print("success");
}
else
{
print("failure");
}
break;
default:
?>
<form method="post" name="form1" action="mypage_name.php?action=Login">
<table name="login_menu" width="100" background="pic_1.jpg">
<th>
User info
</th>
<tr>
<td>
Username:
<br>
<input type="text" name="username" size="10">
</td>
</tr>
<tr>
<td>
Password:
<br>
<input type="password" name="password" size="10">
</td>
</tr>
<tr>
<td>
<input type="submit" value="Login">
</td>
</tr>
<tr>
<td>
<b>(</b><a href="register.html">register</a><b>)</b>
</td>
</tr>
</table>
</form>
<?PHP
break;
} //end of switch.
?>
</body>
</html>
[/PHP]

Please note that you should replace "mypage_name.php" with the name of your page. I am sure that you could use phpself() if you really wanted, but you must have the "?action=Login" part for it to work.

If it's 1 user, just use http auth.

[PHP]<?
if (!isset($PHP_AUTH_USER))
{
header("WWW-Authenticate: Basic realm=\"Protected Page\"");
Header("HTTP/1.0 401 Unauthorized");
exit;
}

else if(($PHP_AUTH_USER=="user") && ($PHP_AUTH_PW=="password"))
{
echo "You got in...";
//place page content or re-direct ehre
}

//part 3
else
{
echo "Sory dude, wrong password";
//it didn't work
}
?>[/PHP]
