Hello,
assume that you need to compare two values from a submitted form to determine values are valid or not.
For example, if you have a date picker with
year,
month and
day values, you need to check both month and day values to see whether the date is valid, because months can have 28, 29, 30 or 31 days.
I cannot implement a validator callback for this situation, since it needs two parameters: month and day.
I thought maybe I can do the validation after the calling the
$this->form_validation->run() and cancel the valid status and repopulated the form and data; but I don't know how.
I appreciate you help.
