codeignitorで画像をアップロードする方法

Question

codeignitorのコピー先フォルダに画像をアップロードできません。コントローラ/管理フォルダの下にsiteという名前のコントローラを1つ作成しました。モデルフォルダの下に1つのモデルを追加しました。 view_addsiteという名前のviewフォルダに1つのビューを作成しました。私はmysqlの中にsitesettingsという名前のテーブルを1つ作成し、そのテーブルに14個のカラムが追加されています。テーブル内のimage.pleaseを除いて、コードを見つけて助けてください。詳細について

public function do_upload() 
{ 
    $config['upload_path']   = './uploads/'; 
    $config['allowed_types']  = 'gif|jpg|png'; 
    $config['max_size']    = 100; 
    $config['max_width']   = 1024; 
    $config['max_height']   = 768; 
    $this->load->library('upload', $config); 

    if (! $this->upload->do_upload('userfile')) 
    { 
      $error = array('error' => $this->upload->display_errors()); 
      $this->load->view('upload_form', $error); 
    } 
    else 
    { 
      $data = array('upload_data' => $this->upload->data()); 
      $this->load->view('upload_success', $data); 
    } 
}

をあなたのformタグに にenctype = "multipart/form-データ" が欠落しても、単に画像入力ボックスの後</form>を削除しています。
