Question

我的表单验证错误已停止工作，昨天正常工作，我一定做错了什么但似乎无法找到它。

当我点击注册而不填写任何信息时，它只会重定向到加载视图的admin_login.php。

admin_login.php //控制器文件

<?php
//session_start();
defined('BASEPATH') OR exit('No direct script access allowed');
class Admin_login extends CI_Controller {
 function __construct()
{
    parent::__construct();
    $this->load->helper('form');
    $this->load->helper('url');
    $this->load->library('session');
    $this->load->model('loginModel');   
}
   public function index()
   {
      $this->load->view('admin_view');
   }
   public function login()
   {
    // Load session library
    $this->load->library('form_validation');
    $this->form_validation->set_rules('admin', 'user_name', 'required|alpha');
    $this->form_validation->set_rules('password', 'Password', 'required');

                if ($this->form_validation->run() == FALSE)
            {

                 return redirect('admin_login');
                    //$this->load->view('admin_view');
                }
            else
            {       
                //echo "successful validation <br>";
                 $admin = $this->input->post('admin');
                 $password = $this->input->post('password');
                 $login_id = $this->loginModel->admin_login($admin, $password);
                         if($login_id)
                {
                  echo "valid admin_name and user <br>";
                  //$this->session->set_userdata('id', $login_id);


                  //return redirect('listing');
                 $this->load->view('listing');
                }
                else
                {
                  //$this->session->set_flashdata('flashError','invalid user_name/password');
                  redirect('admin_login');
                  echo "wrong admin_name or password";
                }                   
           }
        }
}

admin_view.php //查看文件

<?php

defined('BASEPATH') OR exit('No direct script access allowed');

Answer 1

将此更改为

<?php  echo form_open('admin_login/login'); ?>

到

<?php  echo form_open('Admin_login/login'); ?>

您的班级名称是 Admin_login ，但您尝试打开 admin_login 类

Answer 2

始终使用$ this-＆gt; load-＆gt; view（）; 而是redirect（）;功能。重定向功能不会显示任何验证错误消息。

未显示任何验证错误。我正在尝试在验证错误时获取错误消息
