I'm attempting to make an HTML form with three different images that do three different actions. The buttons must be images, and all three buttons must be in the same form.

I made this simple script to test. Does anyone know a more elegant way to do this? I can't do three separate forms, because I need the data in the text box. Note that this is purely academic, as I am doing nothing exciting with the form data, I just thought it was an interesting problem. 
#!/usr/bin/perl -Tw
use CGI;
use CGI::Carp qw( fatalsToBrowser );
use strict;

my $cgi = CGI->new();

my $mode   = $cgi->param('mode');
my $action = get_action( $cgi );

my $date = scalar localtime();

print $cgi->header();

print <<EndHTML;
  <html>
  <head><title>Test Three: ( $action : $mode )</title></head>
  <body>
  <form method="get" action="test_three.cgi">
  <input type="text" name="date" value="$date"><br>
  <input type="image" name="invite" alt="Invite" src="invite.gif">
  <br>
  <input type="image" name="view" alt="View Results" src="view.gif">
  <br>
  <input type="image" name="leave" alt="Leave" src="exit.gif">
  <br>
  <input type="hidden" name="mode" value="1">
  </form>
  </body>
  </html>
EndHTML


sub get_action {
  my $cgi = shift;
  my $action;
  my @actions = qw( view invite leave );

  TRY:
  for my $try ( @actions ) {
    if ( $cgi->param("$try.x") || $cgi->param("$try.y") ) {
      $action = $try;
      last TRY;
    }
  }

  $action;
}
