You could try something like this:
<?php
$mysql_host = "localhost";
$mysql_login = "username";
$mysql_pw = "password";
if($submit == "Submit"){
$db_security = mysql_connect($mysql_host, $mysql_login, $mysql_pw);
mysql_select_db("dbname",$db_security);
$sql = "UPDATE tablename SET name = '$name' WHERE id = '$id'";
$result = mysql_query($sql);
}else{
echo "<FORM ACTION='$PHP_SELF' METHOD='post'>";
echo "ID : <INPUT TYPE='id' NAME='name' SIZE='5'><BR>";
echo "Name : <INPUT TYPE='text' NAME='name' SIZE='75'><BR>";
echo "<INPUT TYPE='submit' NAME='submit' VALUE='Submit'>";
echo "</FORM>";
}
?>

Also, read this (which is taken from the php.ini):
<snip>
E_NOTICE - run-time notices (these are warnings which often result
; from a bug in your code, but it's possible that it was
; intentional (e.g., using an uninitialized variable and
; relying on the fact it's automatically initialized to
an
; empty string)
</snip>
So, by using ~E_NOTICE in the statement I last showed you, you suppress
those WARNINGS, if this is the case with your problem.

That won't work because you have to actually send the form before using the
variable $username.
Check your php.ini and make sure you have your error_reporting line set
like this:
error_reporting = E_ALL & ~E_NOTICE
hope that helps,

Yours did not work as it either. Thanks for the attempt. Although a few
things about your code that I thought my be the problem:
- You had "<? " and not "<?php" ... even after changing that it had the same
affect (I do not know if that is okay or not, that's why I changed it)
-The "action" setting is seen as not even a blank space when coverted to
HTML (because it unassigned or is that server default variable?)
-Everything else was normal and I've seen before and it still does not work.
I guess I will definately be getting Linux.
THANK YOU for trying to help me get this work. I wish I could simply use XP
for this stuff, but I don't have a problem getting Linux and using it either
so thank you!

You may want to do some XML export and import. That will give you a
widely compatible data exchange method.
Later, you can use that XML feed to provide syndication contents, etc.
(Think about the future!)

I seem to be having trouble being able to *write* text to a file within a
Windows server. Does anyone know what needs to be done to get this to work?
I've tried making sure that the direcories are set to the maximum
permissions (read/write/execute) to anyone. Still doesn't work.
I'm trying this:
$fp = fopen("test.txt", "w"); flock($fp, 1);
fputs($fp, "testing");
fclose($fp);
and I've tried "a", "a+", "w+", and "w" and no results.
