I presume you only seting $q when it's a POST request to make sure that users only login with POST, but i think you'll still want to have a my $q = CGI->new() since you may want to, say, set $q->cookie or do a $q->header 'location: http://elsewhere.com/' etc regardless of wether the user has posted the form...

CGI::param 'foo' will give you back foo from get/post-age, and will play nice and give you an undef if the form wasn't posted or that field wasn't supplied.

If you're not unconditionally putting something in $q then you can't trust $q to be defined and so you should check that there's something there, every time you want to call something on it. It's only safe to do $q->somestuff() if ref $q ie you can only use methods on $q if it is an object (ie if it's a blessed reference) HTH

    I actually have one more question with regards to retrieving the value in the cookie from a different cgi file. I am using the sample code form the CPAN tutorial 
    $name = $session->param($username);
printf "<input type=\"text\" name=\$username\" value=\"%s\" />", $name
+;

    Just wondering should as in the creating the session, $name here be defined as my $name ->new CGI() or just my $name also the value that i passed into the session was 
     $name = $query->param($username);
        $session->param($username, $name);

    [download]
    so in retrieving the cookie am i right to put $username into the "param" field in the line $name = $session->param($username); and into the name field in the line 
    printf "<input type=\"text\" name=\$username\" value=\"%s\" />", $name
+;

      I'm not sure if you've read it, but Ovid wrote a CGI course that you may be interested in

      Also, merlyn wrote some neat Web Techniques Columns that may interest you.

      Oh, and I think there's a book on Perl CGI too... ;)

    Adding a  my $q = CGI->new() seemed to do the trick, thanks for all the help, appreciate it!
