笨 - 如何顯示從do_upload

Question

我想顯示對重定向link.here內容插件的成功消息的錯誤消息是我的控制器代碼： -

public function do_upload($field) { 
     $config['upload_path'] = './uploads/'; 
     $config['allowed_types'] = 'gif|jpg|png'; 
     $config['max_size'] = '100000'; 
     $config['max_width'] = '3000'; 
     $config['max_height'] = '3000'; 

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

     if (!$this->upload->do_upload($field)) { 
      $error = array('error' => $this->upload->display_errors()); 

      return $error; 
     } else { 

      $updata =$this->upload->data(); 
      $data = $updata['raw_name'].$updata['file_ext']; 
      return $data; 
     } 


    } 


public function index() { 

$this->load->model('blog'); 

     if(isset($_POST['post']) && (!empty($_POST['post']) || strlen($_FILES['inputUpProfile']['name']) > 0)){ 
     if(strlen($_FILES['inputUpProfile']['name']) > 0) 
     { 
     $pic = $this->do_upload('inputUpProfile'); 
     print_r($pic); 
     if ($this->input->post('post') == ''){$type="image";} else {$type="image-with-text";} 
     } 

     else {$pic = ""; $type = "text"; } 

      $result = $this->blog->addPost($_SESSION['user_id'], $type , $this->input->post('post'),$pic); 
     } 
$this->template->build('home_view',$this->data); 
} 

時上傳圖片超過3000的大向我顯示此消息

Array ([error] => 

The filetype you are attempting to upload is not allowed. 
) 

如何在我的視圖中讀取此錯誤？

============================================== ==

更新： -

錯誤messagelike這樣的： -

Array ([error] => 

The filetype you are attempting to upload is not allowed. 
)

Answer 1

$pic = $this->do_upload('inputUpProfile'); 
$this->data['upload_error'] = $pic['error']; 

然後在視圖：

echo $upload_error; 

Answer 2

，如果你有像

Array ([error] => 
    The filetype you are attempting to upload is not allowed. 
) 

錯誤的控制器，你可以像

if (!$this->upload->do_upload($field)) { 
    $error = array('error' => $this->upload->display_errors()); 
    $this->session->set_flashdata('error',$error['error']); 
    redirect('your_function_which_loads_the_view','refresh'); 
} 

，並在視圖頁面做類似

if($this->session->flashdata('error')){echo $this->session->flashdata('error');} 

請讓我知道，如果你面對任何問題。
