This post may be outdated due to it was written on 2007. The links may be broken. The code may be not working anymore. Leave comments if needed.
my @a = ( 'a', $c->req->param('a'), 'b', $c->req->param('b'), 'c', undef , 'd',, 'f' );$c->res->body(Dumper(\@a));
when we try "?b=1", output:
$VAR1 = [

see? $c->req->param('a') is NOT undef.
so when u try something like
$rs->update( {
column1 => $c->req->param('column1'),
column2 => $c->req->param('column2')
} );
then if column1 param is not specified, this would raise error because $rs try to update column1, column2, $c->req->param('column2'). we want 4 but u give me 3.

so man, be careful of that. :)
