How i can upload File in CI

[eluser]An Phu[/eluser]
I'm using upload file library in CI to upload xls files but i can't use it . when i execute upload site it always say :"The filetype you are attempting to upload is not allowed."

This my code :

Code:

function do_upload()
    {
    $config['upload_path'] = './uploads/';
        $config['allowed_types'] = 'xls';
        $config['max_size']    = '4096';
        
      
        $this->load->library('upload', $config);
    
        if ( ! $this->upload->do_upload())
        {
            $error = array('error' => $this->upload->display_errors());
            
            $this->load->view('upload_form', $error);
        }    
        else
        {
            $data = array('upload_data' => $this->upload->data());
            
            $this->load->view('upload_success', $data);
        }
    }

and this is my define in mine file :

Code:

'xls'    =>    array('application/excel', 'application/vnd.ms-excel', 'application/msexcel'),

In an other thread I read that you need to define allowed
filetypes as following if the excel file is made with Excel 2007:

Code:

$config['allowed_types'] = 'xls|xlsx'; // xlsx is needed for excel 2007

What mime type does the browser send?
Add it to the $mimes array in mimes.php.

It is not that firefox can't upload xls. The problem is (sometimes) that different
browsers handle mime types of files in a different way.

So how to correct it ?

Find out which mime type the browser sends, then add this mime type to the $mimes array:

Code:

$mimes = array( ...
                'xls'    =>    array('application/excel', 'application/vnd.ms-excel', 'add-your-type-here'),
...
