I am working in a codeigniter's file upload page in one of my projects. I am not able to upload Fast Report(.fr3) file types. I am using the following code
$config['allowed_types'] = 'fr3';
$this->load->library('upload', $config);
What should I do to upload these types of files through codeigniter. I could not find a solution in codeigniter documentation. Thanks In Advance..
