Answer 1

$config['upload_path'] = 'uploads/category/'.$id.'/';
        //echo $file_name;die;
        //echo $config['upload_path'];
        $config['allowed_types'] = 'gif|jpg|jpeg|png';
        $config['max_size'] = '2048';
        $config['max_width'] = '1920';
        $config['max_height'] = '1280';
        $this->load->library('upload');
         foreach ($_FILES as $key => $value) {
            //print_r($key);

            if (!empty($key['name'])) {

                $this->upload->initialize($config);
                if (!$this->upload->do_upload($key)) {
                  // echo 'test';die;
//                    rmdir('uploads/category/'.$id);
                    $errors = $this->upload->display_errors();
                    flashMsg($errors);
                }
}
}
