Question

我已经检查了我的代码可能出错的所有可能的事情，但它仍然显示我的错误。请帮忙。

 Unable to access an error message corresponding to your field name Username.(check_username)

这是我的代码：

 public function index()
    {
        if ( ! file_exists(APPPATH.'/views/login.php'))
        {
            /* Whoops, we don't have a page for that! */
            show_404();
        }
        $this->load->helper('security');    
        $this->load->library('form_validation'); // Including Validation Library.
        $this->form_validation->set_error_delimiters('<div class="error">', '</div>'); // Displaying Errors in Div
        $this->form_validation->set_rules('username', 'Username', 'trim|required|xss_clean|callback_check_username'); // Validation for Username Field
        $this->form_validation->set_rules('password', 'Password', 'trim|required|xss_clean'); // Validation for Password field.         

        if ($this->form_validation->run() == FALSE) {
            $this->load->view('login');         
        }

        function check_username($username)
        {               
            if ($username == 'test') {                
                 $this->form_validation->set_message('check_username','already exists.');  
                 return false;
            } else {
                return TRUE;
            }               

        }   
    }

Answer 1

在配置文件中执行$config['global_xss_filtering'] = TRUE;。

Codeigniter-3 xss_filtering中的

不是form_validation的一部分。

Answer 2

您必须在系统文件夹中添加验证语言。查看视频
