Question

When registering new user, user can upload photo or leave it as default, but in CI if no file is chosen $this->upload->do_upload() returns false. How can I bypass exactly this error. Below is my way:

if($this->form_validation->run()==FALSE)
            {
                $this->load->view('add_item_form', array('error' =>''));
            }
            else
            {
                $config['upload_path'] = 'images/';
                $config['allowed_types'] = 'gif|jpg|jpeg|png';
                $config['max_size'] = '100';
                $config['max_width'] = '1024';
                $config['max_height'] = '768';

                $this->load->library('upload', $config);
                $no_photo_error = "<p>You did not select a file to upload.</p>";

                if(!$this->upload->do_upload() AND $this->upload->display_errors() != $no_photo_error)
                {
                    $error = array('error' => $this->upload->display_errors());
                    $this->load->view('add_item_form', $error);
                }
                else
                {
                    $data['title'] = 'Add Item';
                    $this->load->view('success', $data);
                }
            }
        }

// Check if we are even trying to upload anything
if ( ! ($_FILES AND $_FILES['userfile']['name']))
{
      // do_upload() logic here
}
else
{
      // no files selected for upload
}
