Date validation CI 1.7

Not sure if i fully understand your problem... but this may help

You CAN do without the actual element in the form

Code:

$this->form_validation->set_rules('date_of_birth', 'Birthday', 'required');

IF you do this before it (not tested by i'm pretty sure)

Code:

$_POST['date_of_birth'] = $this->input->post('day').' '.$this->input->post('month').' '.$this->input->post('year');
$this->form_validation->set_rules('date_of_birth', 'Birthday', 'required');

So in other words concatenate each drop down together (however you need to) and trick the form validation into thinking you posted that field.
