php - 如何在codeigniter中上传图片

Question

我无法在 codeigniter 的目标文件夹中上传图像，我在controller/admin 文件夹下创建了一个名为 site 的 Controller 。我在模型文件夹下添加了一个模型，名称为model_view，最后在 View 文件夹中创建了一个 View ，名称为view_addsite。我在 mysql 中创建了一张名为 sitesettings 的表，并在该表中添加了 14 列。听到的问题是除图像之外的所有字段都添加到表中。请找到代码。

           controller(site)::

        public function add()

        $datte = date('Y-m-d H:i:s');
       if(!$this->input->post('buttonSubmit'))
         {
          $data['message'] = '';
            $this->load->view('admin/view_addsite', $data);
        }
         else
         {
           //$this->load->library('form_validation');
           if($this->form_validation->run('addsite'))
            {   
                    $config['upload_path']          = './uploads/';
                  $config['allowed_types']        = 'gif|jpg|png';
                 $config['max_width']    = '2048';
                 $config['max_height']   = '2048';
                  $this->load->library('upload', $config);
