Code:

if ( ! $this->input->post('hours'))
{
    // Require your start/stop times.
}
else
{
    // Require hours
}

I was originally going to go with that method, but the problem was that I wanted the user to be able to fill in timeStart, timeStop and hours, or hours, or timeStart and timeStop. If I had the write the code for that it then it would have been over complicated for the little bit I wanted.

2) Don't use form validation at all, and check the values / create error messages manually.

I considered that as well, but the reason I chose to do this project in CodeIgniter is because I have a much larger project coming up that is required to be done in CI, and thus I would like to try to understand CI's features to the best of my ability before I start the coding process on the other.
