I am running php-4.2.3, I am using this code:
The HTML:
<HTML>
<HEAD></HEAD>
<BODY>
<FORM METHOD=GET ACTION="text.php">
Who is your favourite author?
<INPUT NAME="Author" TYPE="TEXT">
<BR>
<BR>
<INPUT TYPE=SUBMIT>
</FORM>
</BODY>
</HTML>
The PHP:
<HTML>
<HEAD></HEAD>
<BODY>
Your favorite author is:
<?php
echo $Author;
?>
</BODY>
</HTML>
Can anyone see why it would give me the error:
Notice: Undefined variable: Author in c:\inetpub\wwwroot\php\text.php on
line 6
Any help would be appreciated. thanx

Ah crap, prematurely sent! I need food/coffee..
that said, lemme clarify some things.
The reason you're getting your errors is because PHP has error_reporting set to
E_ALL by default, whereas in older versions, E_NOTICE level warnings were
suppressed.
Another change is that GET, POST, etc.. variables are not, by default, copied
into global scope. (That is, 'register_globals = off' in php.ini).
There've been hundreds of posts on this list about $author in chapter 3,
register globals, and error reporting.
You received two replies already:
> I think that you should use the POST method, not the GET one...
> Hope it helps..
At the risk of sounding harsh, this is a useless suggestion. You're getting
the error because $Author doesn't exist because it wasn't copied from
$_GET['Author'] into a global variable. Changing to POST would yield the same
results for a similar reason -- the value wasn't copied from $_POST['Author'].
> turn register_globals on in php.ini file
This suggestion will fix your problem at the cost of not explaining WHY you
should or should not turn register_globals = on in php.ini.
For more info, search the list archives for register_globals, and read up on
why PHP changed the default values of error_reporting and register_globals
here:

Take care,
Nik
