Most likely it has to do with your error_reporting setting. See :
http://uk.php.net/manual/en/phpdevel-errors.php#internal.e-notice
http://uk.php.net/manual/en/features.error-handling.php
Level E_NOTICE produces Warnings such as "Undefined Variable", so, doing
the following :
echo $iamnotset;
Produces such a Error/Warning. Any "direct" use of $iamnotset will, which
is why functions such as isset() and empty() exist :
if (isset($var)) echo $var;
I am guessing either you have :
if ($submit) {
// process form and no Warnings as $submit is set
} else {
// show form and WILL show the Warnings as $submit is not set
}
Consider :
if (isset($submit)) {
It's not uncommon to have E_NOTICE off but good little PHP developers
develop with error_reporting turned up full blast, E_ALL in da house!
Second, perhaps you expect register_globals to be on, see the following :
http://uk.php.net/manual/en/configuration.php#ini.register-globals
http://uk.php.net/manual/en/security.registerglobals.php
If off, foo.php?fruit=apple will not create $fruit but rather, you'd go
through a predefined variable like : $HTTP_GET_VARS['fruit'].
