[!--quoteo(post=357555:date=Mar 23 2006, 12:05 PM:name=wildteen88)--][div class=\'quotetop\']QUOTE(wildteen88 @ Mar 23 2006, 12:05 PM) [snapback]357555[/snapback][/div][div class=\'quotemain\'][!--quotec--] If you parsing the variable [b]person[/b] over the url then you will want to use the $_GET superglobal array instead, ie $_GET['person']; This is because you have register_globals turn off. So you will need to use the superglobal array instead. [/quote] Thanks for letting me know that the cause was register_globals was off. I turned it on and it worked. However, this does lead to security issues as stated in the narratives in php.ini, but the code I am going through is research anyway so for the time being that doesn't matter. I will also look at superglobal arrays at some point as well. I tried the $_GET['person'] in my code and it still didn't work until I turned register_globals on. Could you please post the alternative code to me (Ie. Your version with the $_GET change) so I can see what I have to do in future if I intend to leave register_globals turned off. Thanks, Nick.

Hi Guys. Yep, am a newbie and the second bit of code I write wont work (the first was helloworld - would be difficult to not get that working!) Anyway, the code I am using is: (Who_are_you.php) <html> <head> <title>Who Are You?</title> </head> <body> <form action="you_are.php"> Please enter your name:<br /> I am... <?php print('<input type="text" name="person" value="' . $person . '"size="15" />'); ?> <input type="submit" value="Go!" size="15" /> </form> </body> </html> (You_are.php) <html> <head> <title>You Are ...</title> </head> <body> <?php print('Well, hello ' . $person . ', nice to meet you!'); print('<br />'); print('<a href="who_are_you.php?person=' . urlencode($person) . '"> Back to who are you?</a>'); ?> </body> </html> The output I get is: (Who are you.php): Please enter your name: I am... Notice: Undefined variable: person in c:\Inetpub\wwwroot\PHP-tests\Mastering PHP 4.1\Listing 1.3\who_are_you.php on line 9 NB. It does display the textbox and button, and when I submit I get: Notice: Undefined variable: person in c:\Inetpub\wwwroot\PHP-tests\Mastering PHP 4.1\Listing 1.3\YOU_ARE.php on line 7 Well, hello , nice to meet you! Notice: Undefined variable: person in c:\Inetpub\wwwroot\PHP-tests\Mastering PHP 4.1\Listing 1.3\YOU_ARE.php on line 9 Back to who are you? the value $person is passed over in the url: [a href=\"http://mysql_server/PHP-tests/Mastering%20PHP%204.1/Listing%201.3/you_are.php?person=nick\" target=\"_blank\"]http://mysql_server/PHP-tests/Mastering%20...php?person=nick[/a] Oh, and I am using PHP 5.1.2 on IIS5 (Win XP Professional). Nick. Hope someone can help. Regards, Nick.
