在Codeigniter中上传 - 不允许您尝试上传的文件类型

问题描述

我收到错误：当我尝试上传任何文件时，我们不允许尝试上传的文件类型。

  if（！empty（$ _ FILES ['proof_of_purchase'] ['name']））{
 $ config ['upload_path'] ='./uploads/invoices/'; 
 $ config ['allowed_types'] ='gif | jpg | jpeg | png | pdf | bmp'; 
 $ config ['max_size'] ='3000'; 
 $ this-> load-> library（'upload'，$ config）; 
 
 //如果有错误，返回并显示
 if（！$ this-> upload-> do_upload（'proof_of_purchase'））
 {
 $ data ['error'] = $ this-> upload-> display_errors（）; 
 $ data ['include'] ='pages / classic-register'; 
} else {
 $ data ['upload_data'] = $ this-> upload-> data（）; 
 $ filename = $ data ['upload_data'] ['file_name']; 
} 
} 
  

我试过了许多不同的文件 - gif& jpeg并且每次都得到相同的错误。

var_dump（$ _ FILES）;给我：

  array（1）{[proof_of_purchase] => array（5）{[name] => string（28）2010-12-04_00019.jpg[type] => string（10）image / jpeg[tmp_name] => string（19）D：\temp\php2BAE.tmp[error] => int（0）[size] => int（58054）}} 
  

我检查了mime配置，它包含正确的东西。示例：

 'jpeg'=> array（'image / jpeg'，'image / pjpeg'），
'jpg'=> array（'image / jpeg'，'image / pjpeg'），
'jpe'=> array（'image / jpeg'，'image / pjpeg'），
  

长在这，它的驱动我坚果！任何想法都会非常有帮助。

解决方案

如果您使用Codeigniter版本2.1.0， 。有关详情，请参见。

基本上，我做的是修改文件上传类中的几行代码（位置：./system/libraries/Upload.php）

1）修改行号1044

：

  $ this-> file_type = @mime_content_type（$ file ['tmp_name']）; 
 return; 
  

：

  $ this-> file_type = @mime_content_type（$ file ['tmp_name']）; 
 if（strlen（$ this-> file_type）> 0）return; 
  

2）修改行号1058

from：

  @exec（'file --brief --mime-type'。escapeshellarg（$ file ['tmp_path'] ），$ output，$ return_code）; 
  

：

  @exec（'file --brief --mime-type'。escapeshellarg（$ file ['tmp_name']），$ output，$ return_code） 
  

正如你可能看到的，行1058尝试使用不存在的数组值。 p>

I am getting the error: The filetype you are attempting to upload is not allowed when I try to uplaod any file.

if(!empty($_FILES['proof_of_purchase']['name'])) {
    $config['upload_path'] = './uploads/invoices/';
    $config['allowed_types'] = 'gif|jpg|jpeg|png|pdf|bmp';
    $config['max_size'] = '3000';
    $this->load->library('upload', $config);

      // if there was an error, return and display it
    if (!$this->upload->do_upload('proof_of_purchase'))
    {
        $data['error'] = $this->upload->display_errors();
        $data['include'] = 'pages/classic-register';
    } else {
        $data['upload_data'] = $this->upload->data();
        $filename = $data['upload_data']['file_name'];
    }
}

I have tried many different files- mostly gif & jpeg and get the same error each time.

var_dump($_FILES); gives me:

array(1) { ["proof_of_purchase"]=> array(5) { ["name"]=> string(28) "2010-12-04_00019.jpg" ["type"]=> string(10) "image/jpeg" ["tmp_name"]=> string(19) "D:\temp\php2BAE.tmp" ["error"]=> int(0) ["size"]=> int(58054) } }

I have checked the mime config and it contains the right stuff. Example:

'jpeg'  =>  array('image/jpeg', 'image/pjpeg'),
'jpg'   =>  array('image/jpeg', 'image/pjpeg'),
'jpe'   =>  array('image/jpeg', 'image/pjpeg'),

I've spent far too long on this and it's driving me nuts! Any ideas would be extremely helpful.

解决方案

If you're using Codeigniter version 2.1.0 there is a bug in the Upload library. See http://codeigniter.com/forums/viewthread/204725/ for more details.

Basically what I did was modify a few lines of code in the File Upload Class (Location: ./system/libraries/Upload.php)

1) modify Line number 1044

from:

$this->file_type = @mime_content_type($file['tmp_name']);
return;

to this:

$this->file_type = @mime_content_type($file['tmp_name']);
if (strlen($this->file_type) > 0) return;

2) modify line number 1058

from:

@exec('file --brief --mime-type ' . escapeshellarg($file['tmp_path']), $output, $return_code);

to this:

@exec('file --brief --mime-type ' . escapeshellarg($file['tmp_name']), $output, $return_code);

As you can probably see, line 1058 tries to use an array value that does not exist.
