php codeigniter mime-types codeigniter-2

CodeIgniter: "The filetype you are attempting to upload is not allowed."

I'm experiencing a very odd upload problem. Here's the relevant view file:

<form action="http://localhost/index.php/temp/upload/" method="post" enctype="multipart/form-data">
    <fieldset>
        <input type="file" name="userfile"/>
        <input type="submit" value="Upload"/>
    </fieldset>
</form>

And here's my temp controller's upload() method:

public function upload()
{
    $config['upload_path']   = FCPATH . 'uploads' . DIRECTORY_SEPARATOR;
    assert(file_exists($config['upload_path']) === TRUE);
    $config['allowed_types'] = 'avi|mpg|mpeg|wmv|jpg';
    $config['max_size']      = '0';

    $this->load->library('upload', $config);
    if ($this->upload->do_upload('userfile') === FALSE)
    {
        // Some error occured
        var_dump($this->upload->display_errors('', ''));
        var_dump($_FILES);
    }
    else
    {
        // Upload successful
        var_dump($this->upload->data());
    }
}

When I upload an AVI video, everything works fine. When I upload, say, a WMV video, I get the following var dumps:

string 'The filetype you are attempting to upload is not allowed.' (length=57)

array
  'userfile' => 
    array
      'name' => string 'wmv.wmv' (length=7)
      'type' => string 'video/x-ms-wmv' (length=14)
      'tmp_name' => string 'C:\wamp\tmp\php2333.tmp' (length=23)
      'error' => int 0
      'size' => int 83914

The "wmv" extension is being interpreted as the MIME type: video/x-ms-wmv. This should be fine since my config/mimes.php has the following:

'wmv' =>  array('video/x-ms-wmv', 'audio/x-ms-wmv')

It's a similar situation when I try uploading other files. So far, the only one that seems to work is my test AVI video.

Any ideas what might be wrong?

UPDATE 1:

One my machine, only AVI uploads. On another developer's machine, no files upload. On yet another developer's machine, all supported files upload. Are these browser or server issues?

Solution

You are using Firefox, aren't you?

You could try looking at system/libraries/Upload.php line 199:

$this->_file_mime_type($_FILES[$field]);

Change that line to:

$this->_file_mime_type($_FILES[$field]); var_dump($this->file_type); die();

Then do upload your .wmv file. It would show something like application/octet-stream or whatever. Add that to your mimes.php. Hope this help =)
