I have a library function that sets up my forms, and submits data. They're long, and they work, so I'll spare you reading my code. :)

I simply need a way for my functions to determine how to handle the data.

Until now, the function did one thing: Submit a report for the current user. NOW, the client has requested that an administrator also be able to complete a form--this means that the form would be filled out, and it would CREATE a user at the same time, whereas the current function EDITS and is accessed by an EXISTING user.

Do I need a separate function to do essentially the same thing?

How do I make one function perform two tasks? One to update a user, and if there is no user, create one.

Current controller:

function survey()
{
    $id = $this->session->userdata('id');
    $data['member'] = $this->home_model->getUser($id);

    //Convert the db Object to a row array
    $data['manager'] = $data['member']->row();
    $manager_id = $data['manager']->manager_id;
    $data['manager'] = $this->home_model->getUser($manager_id);
    $data['manager'] = $data['manager']->row();
    $data['header'] = "Home";
    $this->survey_form_processing->survey_form($this->_container,$data, $method);

}

Current Library:

function survey_form($container)
{
           //Lots of validation stuff
    $this->CI->validation->set_rules($rules);

        if ( $this->CI->validation->run() === FALSE )
        {
            // Output any errors
            $this->CI->validation->output_errors();
        }
        else
        {
            // Submit form
            $this->_submit();
        }
    $this->CI->load->view($container,$data);

The submit function is huge too. Basically says, "Update table with data where user_id=current user"

I hope this wasn't too confusing. I'll create two functions if need be, but I'd like to keep redundancy down! }
