Form validation combination of two fields

[eluser]Unknown[/eluser]
Hi!

I have a form which has 2 fields, hours(text input) and minutes(dropdown) which make total duration. Total duration must be positive. How can i validate this?

I have a form_validation rule:

Code:

$this->form_validation->set_rules("minutes", 'Minutes', 'required|callback_duration_is_positive');

And i have a callback (which obviously do not work atm):

Code:

function duration_is_positive($minutes) {
        if ($minutes == 0) {
            $this->form_validation->set_message('duration_is_positive', 'Duration has to be positive.');
            return false;
        }
        else
            return true;
    }

Can i pass hours to callback somehow?

Thank you very much!

Yes you can pass hours to call back

Code:

function duration_is_positive($minutes) {
        $hours=$this->input->post('your_hours'); //This is how you call other fields in callback

        if ($minutes == 0) {
            $this->form_validation->set_message('duration_is_positive', 'Duration has to be positive.');
            return false;
        }
        else
            return true;
    }
