in thread simplifying a CGI param request

hashes don't keep them in the order I need. How would I sort them to print out q1, q2, q3 etc in order in a foreach loop?

    You'd take his for loop and instead of putting the stuff in a hash you'd just do something with the number right then and there! 
    for (1 .. 25) {
  my $value = param("q$_");
  print "Value #$_ = $value\n";
}

      This could work or you could drop the "q" from the hash key and then just do a numeric sort on the hash and add it back in at the end.

        Or you could sort it thusly:

        foreach $key( map { $_->[1] }
              sort { $a->[0] <=> $b->[0] }
              map { m/q(\d+)/; [ $1, $_ ] }
              keys %hash ){
  print "$key : $hash{$key}\n";
}
