    {
        $data['groups'] = $this->model_get->getAllGroups();
        $this->load->view("site_header");
        $this->load->view("site_nav");
        $this->load->view('login');
        $this->load->view('content_view');  
        $this->load->view("content_video");

                            if (is_array($groups))
                                {
                                    foreach($groups as $row)
                                    { 
                                      echo '<option value="'.$row->page.'">'.$row->page.'</option>';
                                    }
                                }
                            ?>

尝试：

$this->load->view('content_view', $data);

尝试将数据从db插入CodeIgniter中的下拉列表时显示错误
