Codeigniter — Загрузить фото с формой добавления пользователя

Я хочу знать…

Я никогда не могу загрузить фото в свою папку и базу данных. Я пробовал это тысячу раз. В чем я ошибаюсь, пожалуйста, помогите мне в этом.

Я могу добавить пользователя хорошо. Это не проблема. Но я попробовал это с загрузкой фотографий, которые никогда не загружали ни одной фотографии. Мои коды:

контроллер:

     public function insert () {

$config['upload_path'] = './upload/user/';
$config['allowed_types'] = 'jpg|jpeg|png|gif';
$config['max_size'] = 1024;
$config['max_width'] = 100;
$config['max_height'] = 100;
$config['file_name'] = rand(100,999);
$config['overwrite'] = false;

$this->load->library('upload', $config);
if(!$this->upload->do_upload('userImg')) {

$this->load->view('user');
}


$data = array (
"userUsername" => $this->input->post("userUsername"),
"userPass" => $this->input->post("userPass"),
"userEmail" => $this->input->post("userEmail"),
"userName" => $this->input->post("userName"),
"userSurname" => $this->input->post("userSurname"),
"userImg" => $this->input->post("userImg"),
"userLang" => $this->input->post("userLang"),
"userType" => $this->input->post("userType"),
"userDate" => date('Y-m-d H:i:s'),
);
$insert = $this->db->insert("user", $data);
if($insert) {
redirect(base_url("user"));
}else {

redirect(base_url("user"));

}

}
