我在做什麼form_validation消息名稱字段訪問錯誤？

Question

我想嘗試有效確認密碼與我的確認密碼匹配，但它不會然後它會顯示我一個錯誤，但是當我嘗試設置我的消息用戶名然後告訴我它不能被訪問我是什麼做錯了？但我嘗試更改以我的用戶名提交的名稱，但它不起作用。

new_user控制器

public function new_user(){ 
    $first_name = $this->security->xss_clean(strip_tags($this->input->post('first_name'))); 
    $last_name = $this->security->xss_clean(strip_tags($this->input->post('last_name'))); 
    $profile_id = $this->security->xss_clean(strip_tags($this->input->post('profile_id'))); 
    $password = $this->security->xss_clean(strip_tags($this->input->post('password'))); 
    $username = $this->security->xss_clean(strip_tags($this->input->post('username'))); 
        $data = array(
         'first_name' => $first_name, 
         'last_name' => $last_name, 
         'profile_id' => $profile_id, 
         'password' => password_hash($password, PASSWORD_BCRYPT), 
         'username' => $username, 
        ); 

        $this->form_validation->set_rules('first_name','first_name','trim|required'); 
        $this->form_validation->set_rules('last_name','last_name','trim|required'); 
        $this->form_validation->set_rules('username','username','trim|required|'); 
        $this->form_validation->set_rules('password', 'password', 'trim|required'); 
        $this->form_validation->set_rules('conf_password', 'conf_password', 'matches[password]|required'); 

        $this->form_validation->set_message('first_name', 'Please enter First Name'); 
        $this->form_validation->set_message('last_name', 'Please enter Last Name'); 
        $this->form_validation->set_message('username', 'Please enter Username'); 
        $this->form_validation->set_message('password', 'Please enter Password'); 

        if ($this->form_validation->run() == FALSE) { 
         $this->json($this->form_validation->error_array()); 
        }else{ 
         $this->user->signup($data); 
        } 
       }

我想你應該 替換此

$this->form_validation->set_rules('username','username','trim|required|'); 

收件人：

$this->form_validation->set_rules('username','username','trim|required');
