[quote author="CroNiX" date="1384386338"]Any of the form_helper functions that retrieve a form value need at least one validation rule set up. set_value(), set_select(), set_radio(), set_checkbox(), etc., or they can't get the value.[/quote]
Good to know. Thank-you. Up to this point, this thread was a bit misleading in that regard.
[quote author="CroNiX" date="1384386338"]I don't know why you'd use an empty rule though. I'd at least make a callback function to see if that field was an int 0 or 1, or whatever allowable choices you have. If it goes in the database, it should be validated. What if I edited the form in my browser and sent "3" and that wasn't an allowable or valid choice? Your code would store it.[/quote]
That's a very good point to note, especially for anyone else that may be reading this thread. However, in this case, only somebody logged in as "admin" has access to my form.
