I am developing a script that uses WWW::Mechanize. Some users will have more or less HTML form fields than others, so my script has to accomodate for that.

I have variables like this for data 

$var1_a = "name";
$var1_b = "Richard";
$var2_a = "age";
$var2_b = "12";
$var3_a = "location";
$var3_b = "mars";

Now some of these vars will NOT be used and will be set to ="". A's are the field names, B's are the values.

Is there a better way to set this up? Preferably a way that the user can add INFINITE form fields for WWW::Mechanize to pull through?

Other question is a two parter. If using MY method of hard coding the vars, how do I transfer them to my $mech call the most efficient way? I don't suppose I can put if conditionals in the FIELDS() to see whether certain fields were used. 

    $mech->submit_form(
        form_name => $search_form,
        fields      => {
            $forum_user     => $username,
            $forum_pass    => $password,
        }
    );

2nd question is, if you have a better way of storing the data and looping over the form fields/values, can you post an example?
