title: 0 getting inserted into table fields
body: <p>I have a website done using code igniter. My issue is in the registration form where '0' values getting inserted into my database  table columns without any known submission. i can view the IP address from  which the registrations comes. Since java script validations are given, also one field is readonly in my form, am surprised how '0' get dumped into my table fields. This dummy registration happen 2 or 3 at a time, then after few hours may be another insertion. can someone help to deal with it.</p>
