title: Codeigniter unchecked checkbox value = blank?
body: <p>I have this database where I have to capture a lot of yes/no questions, and the prefered method for the users is checkboxes. Everything is working as it should, except when it comes to retreive and show the values. Unchecked boxes return values of "0"</p>
  
  <p>Is there anyway to either ignore and not display "0" in the reports OR change the default value from "0" to blank"</p>
