So,
In a work that i’m working on, some values of checkboxes and radios have values = 0.
CodeIgniter don’t like them.
Found the solution for it here.
FYI – I fixed this bug. I dont know how to do pull requests – but you need to change Form_validation line 825:
from: if (($field == ” OR $value == ”) OR ($field != $value))
to: if (($field === ” OR $value === ”) OR ($field != $value))Otherwise it doesnt evaluate the 0 correctly.
You probably also need to do it to lines 781 and 869 (set_select() and set_checkbox() )- but I havent tested it
