Re: reason for a "Notice:.." on one site but not another? (Same code.)

It's either the 'error_reporting' configuration directive that's different between the two servers, or 'display_errors', or both. On one server the E_NOTICE bit-field is set in 'error_reporting', and it sounds like 'display_errors' is also set (unless you're seeing that notice in a log file). On the other server, one or the other of those things is not set (or both of them aren't). You can use call ini_get('error_reporting') and ini_get('display_errors'), to see what they're set to on each server. Or just create a small page that only calls phpinfo(), to see all configuration directives. Here's the write-up of the directives (one is right below the other): http://us3.php.net/manual/en/errorfunc.configuration.php#ini.error-reporting As others have pointed out, it's a good idea to call isset() on a POST-variable before trying to get at its value. This will avoid a notice being thrown. Lately I've stopped touching $_POST directly and started using filter_input() instead; this also avoids the problem and provides several other benefits: http://us2.php.net/manual/en/function.filter-input.php The filter_* functions are only available in core since 5.2.0, though.
