[SOLVED] Problem with this code?

[phpcode]

I've been using Abyss web server for awhile but changed to Apache and now I've been getting problems with this code:

 

if ($do == "invalid"){
$msg = "Invalid username/password!<br><br><a href='forgot.php'>Forgot your login details? Click here</a>.";

} elseif ($do == "logout"){
$msg = "Logged out successfully.";
}

if (empty($_SESSION['name']) && empty($_SESSION['pass'])){

ShowForm();

}

$msg = strip_tags($msg, "<a><br>"); 
echo $msg; 

 

(not the full source)

 

Problem I'm having is it doesn't echo the variable msg but it did echo it when I was using Abyss web server.

 

Apache error log:

 

[Thu Jan 10 17:41:57 2008] [error] PHP Notice:  Undefined variable: do in login.php on line 50

 

Does anyone know why it wont work for Apache but does for Abyss?

[kenrbnsn]

Is the variable $msg set before the

<?php
if ($do == "invalid"){
?>

 

If not, that would explain the problem.

Where is $do defined?

[phpcode]

Edit: Found the problem.

 

I forgot to put $do = $_GET['do'];

Ok, where is the value for do coming from?

 

Nevermind
