Im a little confused on how should I get this done

I have Projects which have many Stages and each stage has one Region, Function, and Organization.

I want to save it all at once cause its all coming from the same form. When you create the project you also create the first stage for it

Code:

if($project->save(array($stage, $region, $function, $organization)))
                    {
                            $this->session->set_flashdata('success', 'Project Created');
                            redirect("Welcome");
                    }

I know this code wont work cause regions and functions arent related to projects but I just wanted to show it so that maybe someone could have an idea on how could i get this done
