Subject RE: CGI.pm - Unnamed parameter
Date Tue, 06 Nov 2001 22:43:54 GMT
Hi Ken, 

Try the following: 

my $q = new CGI;

if (defined $q->param('data')) {
 #
 # data was a parameter... 
 #
}
else {
 #
 # data was not a parameter... 
 #
}

cheers,

simran.

James,

Do you have to use CGI.pm?  Why not use the Apache::Request module?
It's much quicker and powerful, IMO.  $apr->path_info() should work
just fine for you, but it's only going to give you the "data" part of
"/script.pl?data."

Also, if you're going to stick to using CGI.pm, why are you saying
"$cgi->param{'foo'}" and not making the method call,
"$cgi->param('foo')"?
