Question

我的控制器。

//Load Login Page------------------------------------------------------------------------------------------------------------------------------------------------------------

    function login(){
            $this->load->helper('form');
            $data['title'] = "Login";
            $this->load->view("view_header",$data);
            $this->load->view("view_login", $data);
    }


    //Login Validation------------------------------------------------------------------------------------------------------------------------------------------------------------

    public function login_validation(){

        $this->load->library('form_validation');

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

        $this->form_validation->set_rules('Password', 'Password', 'required|trim|md5');

        if ($this->form_validation->run()){
            redirect('site/members');
        }
        else{
            $this->load->view('view_header');
            $this->load->view('view_login');
        }

    }

    public function validate_credentials(){
        $this->load->model('model_users');

        if ($this->model_users->canLogin()){
            return true;
        }
        else{
            $this->form_validation->set_message('validate_credentials', 'Incorrect username or password');
            return false;
        }

    }



    //Load Members Page------------------------------------------------------------------------------------------------------------------------------------------------------------

    public function members(){

        $data['title'] = "Members";
        $this->load->view('view_header');
        $this->load->view("view_members", $data);
    }

我的模特

class Model_users extends CI_Model {


    public function canLogin(){

        $this->db->where('Username', $this->input->post('Username'));
        $this->db->where('Password', md5($this->input->post('Username')));

        $query = $this->db->get('user_registration');


        if ($query->num_rows() == 1){
            return true;
        }
        else{
            return false;
        }

    }

我的表格

<?php
  echo form_open('site/login_validation');

  echo form_label('Username:', 'Username');
  echo form_input('Username');
  echo "<br>";

  echo form_label('Password:', 'Password');
  echo form_password('Password');
  echo "<br>";

  echo form_submit('Login', 'Login');

  echo validation_errors();

  echo form_close(); 

  ?>

似乎无法获取我的用户名和密码进行验证。它允许我在没有现有帐户的情况下访问成员页面。因为我一直在关注Youtube教程，所以无法找到问题。

尝试此代码并使用回调函数进行表单验证，您可能需要在routes.php $ route [＆＃39; login＆＃39;] =＆＃34; login / index＆＃34 ;;

请勿使用 MD5 仅将其用于测试。

class Login extends CI_Controller {

public function index() {

$this->load->library('form_validation');
$this->load->helper('form');
$this->load->helper('url');

$data['title'] = "Login";

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

 $this->form_validation->set_rules('Password', 'Password', 'required|trim|md5');

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

$this->load->view('view_header');
$this->load->view('view_login');


} else{

redirect('site/members');

}

}

public function validate_credentials(){
$this->load->library('form_validation');
$this->load->model('model_users');

if ($this->model_users->canLogin()){

return true;

} else{

 $this->form_validation->set_message('validate_credentials', 'Incorrect username or password');
        return false;
    }

}

}

查看

<?php
  echo form_open('login');

  echo form_label('Username:', 'Username');
  echo form_input('username'); // Lower case
  echo "<br>";

  echo form_label('Password:', 'Password');
  echo form_password('password'); // Lower case
  echo "<br>";

  echo form_submit('Login', 'Login');

  echo validation_errors();

  echo form_close(); 

  ?>

表格不会验证用户名和密码
