Re: [PHP] Variables not working!
Try this for a generic fix if it is the globals issue:
Place this somewhere to set to TRUE or FALSE when needed
$GLOBAL_FIX = TRUE;
use an include on every script:
if($GLOBAL_VARS_FIX) {
if( phpversion() = '4.2.0' ) {
extract($_POST);
extract($_GET);
extract($_SERVER);
extract($_ENV);
extract($_COOKIE);
}
}

RE: [PHP] Variables not working!
It is most likely globals. Access the variables by... echo $_GET['fname']; or $_POST['fname']; if you are using post which it doesn't appear you do. Larry PS it is adviseable to leave globals alone in php.ini since it is set that way for security concerns. -Original Message- From: Kaushan [mailto:[EMAIL PROTECTED] Sent: Monday, January 19, 2004 10:44 AM To: [EMAIL PROTECTED] Subject: [PHP] Variables not working!

Turn on register_globals in your php.ini file.

Re: [PHP] Variables not working
Before you get carried away with registering globals, try echoing: $_SERVER[HTTP_USER_AGENT]; Or, for versions prior to 4.1.X, change that to: $HTTP_SERVER_VARS[HTTP_USER_AGENT]; Registering globals is insecure unless you are VERY careful about how every variable you have is defined...

RE: [PHP] Variables not working
Read these: Variables from outside PHP: http://uk.php.net/manual/en/language.variables.external.php It gives an example using $HTTP_POST_VARS. This is but one predefined variable, others can be read about here: Predefined Variables: http://ca.php.net/manual/en/language.variables.predefined.php Also consider extract and import_request_variables, I posted a bit about them awhile back here: http://marc.theaimsgroup.com/?l=php-generalm=101803683730027 And when in doubt, send your script to a call of phpinfo() and it'll provide a ton of useful information.
