您沒有選擇要上傳的文件

這是我的控制器

function post() { 
    $config['file_name'] = 'produk_' . date('Y_m_d_H_i_s'); 
    $config['upload_path'] = './uploads/'; 
    $config['allowed_types'] = 'gif|GIF|jpg|JPG|jpeg|JPEG|png|PNG'; 
    $config['max_size'] = '8000'; 
    $config['max_width'] = '4000'; 
    $config['max_height'] = '2000'; 
    $this->load->library('upload', $config); 
    $this->upload->initialize($config); 
    if (!$this->upload->do_upload()) { 
     echo $this->upload->display_errors(); 
     echo 'Error Bos'; 
    } else { 
     if ($this->_validation() === FALSE) { 
      $this->session->set_flashdata('message', $this->message->message_error('Gagal Menambah Data')); 
      redirect(base_url() . "admin/produk"); 
     } else { 
      $data = $this->upload->data(); 
      $this->_create_thumbnail($data["file_name"]); 
      $this->_create_mini($data["file_name"]); 
      $data_adalah = $this->input->post(); 
      $data_adalah['GambarBesar'] = $data['file_name']; 

      unset($data_adalah['submit']); 
      $this->mproduk->add_record($data_adalah); 
      $this->session->set_flashdata('message', $this->message->message_success('Berhasil Menambah Data')); 
      redirect(base_url() . "admin/produk"); 
     } 
    } 
}

，這我認爲

我有一個proble當我試圖上傳圖片時，我總是收到一條錯誤消息：「您不選擇要上傳的文件。」我的代碼有什麼問題？幫我先生

$這個 - > upload-> do_upload（）函數需要兩個參數1）htmlFieldName 2）pathWhereFileWouldBeUpload –

如果這兩個值不配置以及設置，文件上傳腳本不起作用 –

注意：默認情況下，上傳例程期望文件來自稱爲userfile的表單字段，並且表單也必須是「多部分類型」，並且必須檢查文件夾權限777 –

嘗試改變$this->upload->do_upload()到$this->upload->do_upload('userfile')

我已更改但它仍然不起作用 – innonx

你可以使用add var_dump（$ _ FILES）來調試錯誤;如果你得到null數組，問題出現在你的html代碼中。 –
