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

Question 1

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:wamptmpphp2333.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?

Question 2

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 =)

Question 3

SOLUTION: I've try to upload it to server. But it still gives me the same error. Then i found this: Codeigniter : The filetype you are attempting to upload is not allowed. Yesterday it was fine "The most recent time I have had this is when I upgraded my core Codeiginter version from 2.x to 3.x. I updated the contents of the system directory, but not application/config. I didn't spot the fact that the application/config/mimes.php file is slightly different - the newer version returns an array whereas the old one included it as a var. The fix was to copy in the newer version of mimes.php"

Question 4

Found a nice solution myself. If you want to generate reports in csv format it is very easy with codeigniter. Your model function

function index(){
return $query = $this->db->get('my_table');
    /*
    Here you should note i am returning 
    the query object instead of 
    $query->result() or $query->result_array()
    */
}

Now in controller

function get_report(){
    $this->load->model('my_model');
    $this->load->dbutil();
    $this->load->helper('file');
    /* get the object   */
    $report = $this->my_model->index();
    /*  pass it to db utility function  */
    $new_report = $this->dbutil->csv_from_result($report);
    /*  Now use it to write file. write_file helper function will do it */
    write_file('csv_file.csv',$new_report);
    /*  Done    */
}

No externals are required everything is available in codeigntier. Cheers! If you want to write xml file it is easy too.
Just use xml_from_result() method of dbutil and use write_file('xml_file.xml,$new_report) Visit these links they will help.

Question 5

check 2 things:

First: in your upload controller: make sure to set the correct allowed types

$config['allowed_types'] = 'csv';
$this->load->library('upload', $config);

Second: update the array $mimes in your config/mimes.php:

'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')

UPDATE:

you could use print_r($_FILES) in your upload controller to check for the mime-type missing. this would output something like:

[userfile] => Array
    (
        [name] => teste1.csv
        [type] => application/vnd.ms-excel
        [tmp_name] => C:Program Files (x86)EasyPHP-DevServer-13.1VC11binariestmpphp8BFD.tmp
        [error] => 0
        [size] => 7880
    )

Question 6

Please try below solution.

You have missed dynamic classes adding in div like apps and joomla

<div class="portfolio-item apps joomla col-xs-12 col-sm-4 col-md-3">

added class in above line with your existing code

<?php
foreach($results as $row) {
//code for getting dynamic class names from db
$class = explode(",.", $row->type);
$gettypes = implode(" ", $class); 
?>
<div class="portfolio-item <?php echo $gettypes;?> col-xs-12 col-sm-4 col-md-3">

Hope this work!

Question 7

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.
