Question

我尝试在Codeigniter中开发一个登录系统，但出于某种原因，当表单被提交并显示ERROR LOADING PAGE时。我试图在表单中的action =“”上找到很多可能性，但它总是给我同样的错误。有人可以帮我吗？

我的代码如下：

我的观点signIn.php

<?php include("includes/header.php"); ?>

<body>
  <div id="login" data-role="page" class="outpage">
    <div data-role="header"><h1>login</h1></div>
    <div class="confpage" style="text-align:center;">
      <img src="<?php echo base_url() ?>template/images/logomarca.jpg" />
        <form action="user/login" method="post">
        <input type="text" placeholder="Email" name="email" id="email">
        <input type="password" placeholder="Password" name="password" id="password">
        <button class="buttonDefault" type="submit" name="submit" id="submit">Login</button>
      </form>
      <a data-transition="slide" href="<?php echo base_url(); ?>">Back</a>
    </div>
  </div>
</body>

我的控制器user.php

<?php

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

class User extends CI_Controller{

    public function __construct(){

        parent::__construct();
        $this->load->model('user_model');
        $this->load->helper(array('form', 'url'));
        $this->load->library('form_validation');

    }

    public function signIn(){

        $this->load->view('signIn');

    }


    public function login(){

        $this->form_validation->set_rules('email', 'Email', 'trim|required');
        $this->form_validation->set_rules('password', 'Password', 'trim|required|callback_check_database');

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

            $this->load->view('signUp');

        }else{

            $this->load->view('admin/admin');

        }



    }


    function check_database($password){

        //Field validation succeeded.  Validate against database
        $email = $this->input->post('email');


        //query the database
        $result = $this->user->login($email, $password);

        if($result) {

            $sess_array = array();

            foreach($result as $row){
                    $_SESSION['id'] = $row->id;
                    $_SESSION['fname'] = $row->fname;
                    $sess_array = array(
                                        'id' => $row->id,
                                        'fname' => $row->fname);

                $this->session->set_userdata('logged_in', $sess_array);

            }
            return TRUE;
        }
        else
        {
            $this->form_validation->set_message('check_database', 'Invalid email or password');
            return false;
        }
    }

}

那就是我的模型user_model.php

<?php

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

class User_model extends CI_Model{


public function __contruct(){

    parent::__contruct();


}


    public function signUp($data){

        $this->db->insert('users', $data);

    }


    public function login($email, $password) {

        $password = md5($password);

        $this -> db -> select('id, fname, lname, password');
        $this -> db -> from('users');
        $this -> db -> where('email', $email);
        $this -> db -> where('password', $password);
        $this -> db -> limit(1);

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

        if($query -> num_rows() == 1) {

            return $query->result();

        }else {

            return false;

        }
    }



}

表单操作本身使用的URL不正确。显然，你会收到一个错误。请尝试使用以下网址。

<?php echo site_url(); ?>user/login

希望这可以帮到你。
