Need assist Filtering Comments/Returning Errors to appropriate view.

[eluser]dancrew32[/eluser]
I threw in some pseudocode in comments() because I'm not particularly sure how to do form_open('movie/comments'); and trigger some kind of conditional statement to run through insert_comment($data).

Code:

function comments()
{
    $data['title']    = 'Comments List';
    $data['comments'] = $this->Movie_model->fetchRow($this->uri->segment(3), 'movie_id', 'movie_comments');
    
        if post is detected {
        
        // Data Input
        $data['comment']  = $this->input->post('comment', TRUE); // XSS Filtered?
        $data['author']   = $this->input->post('author', TRUE);
        $data['movie_id'] = $this->input->post('movie_id', TRUE);
        
        insert_comment($data);

    }
    
    $this->load->view('front/movie_comment_view', $data);
}

private function insert_comment($data)
{
    $this->form_validation->set_rules('comment', 'Comment', 'required|min_length[1]|max_length[100]|xss_clean|prep_form');
    $this->form_validation->set_rules('author', 'Author', 'required|min_length[1]|max_length[40]|xss_clean|prep_form');
            
    if ($this->form_validation->run() == FALSE) {
        $this->load->view('front/movie_comment_view', $data);        
    } else {
        $this->Movie_model->insertRow('movie_comments', $data);
        redirect('movie/comments/'. $data['movie_id']);    
    }
}

Sorry for noobin ya..
