Question

我有两个文件上传文件：一个用于图片上传，另一个用于视频上传。现在的问题是，如果我为视频或图像上传了无效的文件类型，它会显示相同的错误

The filetype you are attempting to upload is not allowed.

我需要的是自定义错误，以便视频就像

The video you are attempting to upload is not allowed.

我怎样才能做到这一点？我正在分享视频和图像的代码部分。

查看页码：

<tr>
  <td>
    <label for="video_type">Video Genre <span class="required">*</span></label>
  </td>
  <td>
    <?php 
    $array['']="Select";
    foreach($genre as $row)
    {
      $array[$row->id] = $row->genre;
    }
    echo form_dropdown('video_type',$array, set_value('video_type'));
    ?>
  </td>
  <td>
    <?php echo form_error('video_type'); ?>
  </td>
</tr>
<tr>
  <td>
    <label for="uploader_id">Upload Video <span class="required">*</span></label>
  </td>
  <td>
    <input type="file" name="video"  class="input" value="<?php echo set_value('video'); ?>" />
  </td>
  <td>
    <?php echo form_error('video'); ?>
  </td>
</tr>

控制器：

function index()
{   
  $data['dropdown'] = lang_dropdown();  // multilanguage dropdown list
  $data['language']=$this->session->userdata('site_language');
  $userid=$this->tank_auth->get_user_id();

  if (empty($_FILES['thumb_image']['name']))

        $this->load->library('upload', $config1);
        $this->upload->initialize($config1);

        if (!$this->upload->do_upload('thumb_image'))

          $this->load->view('layout/template',$data);
        }        
      }

      if ($this->Video_model->SaveForm($form_data) == TRUE) // the information has therefore been successfully saved in the db
      {
        $data['successmsg']="Successfully uploaded the video";
      }
      else
      {
        echo 'An error occurred saving your information. Please try again later';
      }

      $this->form_validation->unset_field_data();
      $this->load->view('layout/template',$data);
    }
  }
}

试试这个

if (empty($_FILES['video']['name']))
  {
    $this->form_validation->set_message('required', 'video name incorrect'); //put this line above this statement
    $this->form_validation->set_rules('video', 'Video', 'required');
  }
