CodeIgniter“您尝试上传的文件类型不被允许”。 [英] CodeIgniter "The filetype you are attempting to upload is not allowed."

问题描述

我在搜索很多，并发现很多问题，关于这个问题，不幸的是没有答案确实帮助我。

我试图上传一个png图像，我收到以下错误：

您尝试上传的文件类型不允许。

我遵循此CI指南来构建我的代码： http：/ /codeigniter.com/userguide/libraries/file_uploading.html

这是我得到的：

查看文件：

  [..] 
<？= form_open_multipart（）？& 
< input type =filename =userfilesize =20/> 
< br />< br /> 
< input type =submitvalue =upload/> 
<？= form_close（）？> 
 [..] 
  

我的控制器：

  $ config ['upload_path'] ='./uploads/'; 
 $ config ['allowed_types'] ='gif | jpg | png'; 
 $ config ['max_size'] ='100'; 
 $ config ['max_width'] ='1024'; 
 $ config ['max_height'] ='768'; 
 
 
 $ this-> load-> library（'upload'，$ config）; 
 
 $ xx = array（'upload_data'=> $ this-> upload-> data（））; 
 $ mimetype = $ xx ['upload_data'] ['file_type']; 
 
 var_dump（'Mime：'。$ mimetype）; 
 var_dump（$ _ FILES）; 
 
 if（！$ this-> upload-> do_upload（））
 {
注意:: add（$ this-> upload-> display_errors ，'error'）; 
} 
 else 
 {
 $ data ['upload_data'] = $ this-> upload-> data（）; 
} 
  

正如你可以看到的，我尝试 var_dump

$

>看起来一切都很好：

  array（1）{[userfile] = array（5）{[name] => string（14）imageofm.png[type] => string（9）image / png[tmp_name] => string（18）/ var / tmp / php5cDAZJ[error] => int（0）[size] => int（358）}} 
  

此外，我得到'png'=> ;在 config / mimes.php 中的数组（'image / png'，'image / x-png'）， >

但是，它对所有图片都有效（尚未尝试其他扩展程序）。

帮助尝试。

解决方案

只需编辑 application / config / mimes.php ，并将 csv 的行替换为

：

  csv'=> array（'application / vnd.ms-excel'，'text / anytext'，'text / plain'，'text / x-comma-separated-values'，'text / comma-separated-values'，'application / octet -stream'，'application / vnd.ms-excel'，'application / x-csv'，'text / x-csv'，'text / csv'，'application / csv'，'application / excel' /vnd.msexcel'）
  

I was searching a lot and found many questions regarding this problem, unfortunately none of answers did help me.

I'm trying to upload a png image, and I'm receiving the following error:

The filetype you are attempting to upload is not allowed.

I was following this CI guide to build my code: http://codeigniter.com/user_guide/libraries/file_uploading.html

Here is what I got:

view file:

[..]
   <?= form_open_multipart() ?>
   <input type="file" name="userfile" size="20" />
   <br /><br />
   <input type="submit" value="upload" />
   <?= form_close() ?>
[..]

My controller:

    $config['upload_path']   = './uploads/';
    $config['allowed_types'] = 'gif|jpg|png';
    $config['max_size']      = '100';
    $config['max_width']     = '1024';
    $config['max_height']    = '768';


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

        $xx = array('upload_data' => $this->upload->data());
        $mimetype= $xx['upload_data']['file_type'];

        var_dump('Mime: ' . $mimetype);
        var_dump($_FILES);

        if ( !$this->upload->do_upload())
        {
            Notice::add($this->upload->display_errors(), 'error');
        }
        else
        {
            $data['upload_data'] = $this->upload->data();
        }

As you can see I'm tryin to var_dump the mime type and result is empty.

When I do var_dump($_FILES) it looks like everything is fine:

array(1) { ["userfile"]=> array(5) { ["name"]=> string(14) "imageofm.png" ["type"]=> string(9) "image/png" ["tmp_name"]=> string(18) "/var/tmp/php5cDAZJ" ["error"]=> int(0) ["size"]=> int(358) } }

Also, I got 'png' => array('image/png', 'image/x-png'), line, in my config/mimes.php.

However, it does happend for all images (haven't tried yet other extensions).

I'd appreciate every help attempt.

解决方案

Just edit the mimes.php file in application/config/mimes.php and replace the line for the csv by this one:

'csv' => array('application/vnd.ms-excel', 'text/anytext', 'text/plain', 'text/x-comma-separated-values', 'text/comma-separated-values', 'application/octet-stream', 'application/vnd.ms-excel', 'application/x-csv', 'text/x-csv', 'text/csv', 'application/csv', 'application/excel', 'application/vnd.msexcel')
