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">
        <input type="file" name="userfile"/>
        <input type="submit" value="Upload"/>

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('', ''));
        // Upload successful

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)

  'userfile' => 
      '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?


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?



You are using Firefox, aren't you?

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


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 =)

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"

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(){
    /* 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 */
    /*  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.

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/', 


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/
        [tmp_name] => C:Program Files (x86)EasyPHP-DevServer-13.1VC11binariestmpphp8BFD.tmp
        [error] => 0
        [size] => 7880

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

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!

If you're using Codeigniter version 2.1.0 there is a bug in the Upload library. See 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


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

to this:

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

2) modify line number 1058


@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.
