undefined variable - form

asleeptheyfell

I am running PHP-4.2.3, and am getting an Undefined Variable error when trying to do this:

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>

i can't seem to get the php to recognize "www.nothing.com/whatever.php?Author=whatever as a variable, can anyone see why? thanx

PHP doesn't convert GET variables automaticaly unless you have the "register globals" option turned on in your PHP config. so, you can either turn on "register globals" or, more preferably, you can just access the appropriate global array that your variable is stored in. In your example the 'author' variable will be stored in the $GET superglobal array as $GET['author'], so your code PHP code needs to change like this:

<HTML>
<HEAD></HEAD>
<BODY>
Your favorite author is:
<?php
echo $_GET['author'];
?>
</BODY>
</HTML>

That was quick, thanx. I knew of the "register_globals" thing, but since that is a security risk, I needed a different way to do it. You're much appreciated.
