There isn't a entry named 'cgi-bin/formtomailscript2.cgi' in the array
$_SERVER, so I would guess it could not work.
$_SERVER is just a predefined variable which can be used without to declare
it and which contains information such as headers, paths, and script
locations. An example of the keys it contains is:
$_SERVER["DOCUMENT_ROOT"]
$_SERVER["HTTP_ACCEPT"]
$_SERVER["HTTP_ACCEPT_LANGUAGE"]
$_SERVER["HTTP_CONNECTION"]
$_SERVER["HTTP_HOST"]
$_SERVER["HTTP_USER_AGENT"]
$_SERVER["HTTP_XXXXXXXXXXXXXXX"]
$_SERVER["PATH"]
$_SERVER["REMOTE_ADDR"]
$_SERVER["REMOTE_PORT"]
$_SERVER["SCRIPT_FILENAME"]
$_SERVER["SERVER_ADDR"]
$_SERVER["SERVER_ADMIN"]
$_SERVER["SERVER_NAME"]
$_SERVER["SERVER_PORT"]
$_SERVER["SERVER_SIGNATURE"]
$_SERVER["SERVER_SOFTWARE"]
$_SERVER["GATEWAY_INTERFACE"]
$_SERVER["SERVER_PROTOCOL"]
$_SERVER["REQUEST_METHOD"]
$_SERVER["QUERY_STRING"]
$_SERVER["REQUEST_URI"]
$_SERVER["SCRIPT_NAME"]
$_SERVER["PATH_TRANSLATED"]
$_SERVER["PHP_SELF"]
There would be 2 more keys, in the case the connection is using the https
protocol. None of them will translate a filename to the real path on the
server, but you have to know it. In your case, you could put
action='http://www.smilelearning.com.au/cgi-bin/formtomailscript2.cgi' or
action='/cgi-bin/formtomailscript2.cgi', using a relative path.
