笨照片上传在非允许的类型没有错误警告文件

Question

这里是上传功能：

$config['upload_path'] = './photos/'; 
    $config['allowed_types'] = 'gif|jpg|png'; 
    $config['max_size'] = 1024 * 2; 
    $config['encrypt_name'] = true; 

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

    if (!$this->upload->do_upload("photo_data")) 
    { 
     $this->error = true; 
     $this->response = $this->upload->display_errors('', ''); 
    } 
    else 
    { 
     $this->upload->data(); 
     $this->response = "Photo successfully changed."; 
    } 

    $array = array(
     'error' => $this->error, 
     'response' => $this->response 
    ); 

    return $array; 

不过，为了测试它不容许的文件类型，除了一个，我让我改名的视频，以.JPG并试图把它上传...

它没有继续进行，但它没有也发送一个错误信息......我在upload classreturns false somwhere想......任何想法如何确保它发送一条消息给用户至上？

如何在视图中打印错误？在上传类返回false某处的方法是，你已经签了假的人，即$this->upload->do_upload()

你应该通过这些错误的观点，如果你希望自己的网站显示它们：

这是假设的代码你贴是从控制器：

$array = array(
     'error' => $this->error, 
     'response' => $this->response 
    ); 

$this->load->view('upload_view',$array); 
//instead of returning, as "return" in a controller makes little sense. If you're inside a model, then, get the returned value in a controller and pass it to a view. 

在你的 “upload_view.php” 查看文件：

<div class="<?php $error? 'error' : 'success';?>"><?php echo $response;?></div>
