validation of a checkbox using the "required" rule

Hopefully this makes sense:

Note: You can apply your own custom error messages to any rule, just by setting the message similarly. For example, to change the message for the "required" rule you will do this:

Code:

$this->validation->set_message('required', 'Your custom message here');

Replace ="required" with code above
