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

Question

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.

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')
