Re: Optional fields

You can do this by just using PHP to build your SQL statment.

if (!empty($first_name)) {
  $sql_query .= " first_name = '$first_name' AND";
}

Do that for each of the fields you want to be able to search on.  If they
put something in, then it will be included in the SQL SELECT.  Remember, you
have to strip off the last AND.  You can do this with a simple:

$sql_query = ereg_replace(" AND$", "", $sql_query);
