undefined variable

The view method in your controller:

PHP Code:

public function view($slug=NULL)
     {
         $data['post']=$this->Post_model->get_posts($slug);
         if(empty($data['post'])){
             show_404();
         }
         $data['title']=$data['post']['title'];
         $this->load->view('templates/header');
         $this->load->view('posts/index',$data);
         $this->load->view('templates/footer');
     } 


It clearly says it's loading the posts/index view!!!!!
