You can try with this

 if (is_readable($gambar)) {
            $media_files = $gamba;
            $this->load->library('upload');

            // Get file data
            $type = explode("/", $gamba['type']);
            $cMediaType = $type[0];
            $cMediaName = $gamba['name'];
}

Your controller Code

Change this line of code:

$this->load->library('upload', $config);

To this (do not send the second parameter)

$this->load->library('upload');
