I'm used to write two runmodes for every panel in my application. In your case, they would be login and login_update. Given a method redirect to set the appropriate headers, the code could be the following (not-so-pseudo-code):
# Does nothing except printing the form. # Using sessions you can pass to it an error_message, # for example. # sub login + { my $self = shift; + my $tmpl = $self->load_tmpl( 'login' ); + return $tmpl->output(); + } sub login_update + { my $self = shift; + my $q = $self->query; # Fetch username and password from the form # if ( PASSWORD CORRECT ) { $self->redirect( { rm => 'first_panel' } ); } else { # It could store some useful info in a session, # for example the error message. # $self->redirect( { rm => 'login' } ); } return; }
I use this technique a lot, and it has proven its flexibility and efficiency.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • Outside of code tags, you may need to use entities for some characters:
            For:     Use:
    & &amp;
    < &lt;
    > &gt;
    [ &#91;
    ] &#93;
