in reply to Login Script

The code where you retrieve your form parameters should like something like this:

my $user_name = $cgi_object->param('user_name'} || ''; my $passwd = $cgi_object->param('passwd') || ''; unless ($user_name && $passwd) { # handle cgi param error }

The database query needs to use a placeholder, and check for errors - something like this:

eval { $sth = $dbh->prepare("select pass from users where user=?"); $sth->execute($user_name); }; if ($@) { # handle database error }

Since HTML is stateless, you need to use something like CGI::Session to remember that a particular user is logged in.

Using a framework will make your life much easier. Here's a link to a simple login tutorial I wrote:
RFC: Proposed tutorial - simple login script using CGI::Application

That should help get you started.
