Question

I.e. would you recommend me to use one controller method like this:

function save()
{
    if(!is_bool($this->input->post('')))
    {
        $post_data = $this->input->post('');
        $this->mymodel->save($post_data);
    }
    $this->load->view('myview');
}

Or would you recommend writing it using two methods?

function save()
{
    if(!is_bool($this->input->post('')))
    {
        $post_data = $this->input->post('');
        $this->mymodel->save($post_data);
    }
    redirect('controller/method2')
}

The redirect is the crucial difference here. It prohibits resubmissions from update for example.

How do you do it? Is there another better way?

Answer 1

You should always redirect on a successful form post.
