请帮我修改编辑和删除功能。
这是我的控制器：
class Recipe_controller extends CI_Controller{
function __construct(){
parent:: __construct();
$this->load->library('session');
$this->load->helper('url');

$this->form_validation->set_rules('category', 'Category', 'callback_combo_check');

function view_appetizer(){

}
MODEL：

这是我的VIEW for edit：

我的编辑功能代码可能出现什么问题？忘记删除功能的内容是什么？如何上传图片将其保存在文件夹中，图片文件名将保存在数据库中？我希望有人可以帮助我，我是codeigniter的新人。谢谢
