Question

我在登录时遇到问题我遇到了类似的错误“致命错误：在C：\ xampp \ htdocs \ cms \ application \ controllers \ admin \中调用未定义的方法User_m :: get_by（） user.php在第10行“

这是我的user_m.php模态文件

<run-privileged>

这是我的查看文件login.php

class User_m extends CI_Model{

    protected $_table_name = 'users';
    protected $_order_by = 'name';
    public $rules = array(

        'email' => array(
            'field' => 'email',
            'label' => 'Email',
            'rules' => 'trim|required|valid_email|xss_clean'
            ),

        'password' => array(
            'field' => 'password',
            'label' => 'Password',
            'rules' => 'trim|required'
            )
        );

    public function __construct()
       {
            parent::__construct();

       }

       public function login()
       {
            $user = $this->get_by(array(
                'email' => $this->input->post('email'),
                'password' =>$this->hash($this->input->post('password'))

                ), TRUE);

            if (count($user)) {
                $data = array(
                    'name' => $user->name,
                    'email' => $user->email,
                    'id' => $user->id,
                    'loggedin' => TRUE,
                );
                $this->session->set_userdata($data);
            }
       }

       public function logout()
       {
            $this->session->sess_destroy();
       }

       public function loggedin()
       {
            return (bool) $this->session->userdata('loggedin');
       }

       public function hash($string)
       {
            return hash('sha512', $string . config_item('encryption_key'));
       }
}

这是我的控制器user.php

<div class="modal-header">
   <h3>Log in</h3>
   <p>Please log in using your credentials</p>
  </div>
  <div class="modal-body">


  <?php echo validation_errors(); ?>
    <?php echo form_open(); ?>
    <table class="table">
        <tr>
            <td>Email</td>
            <td><?php echo form_input('email'); ?></td>
        </tr>
        <tr>
            <td>Password</td>
            <td><?php echo form_password('password'); ?></td>
        </tr>
        <tr>
            <td></td>
            <td><?php echo form_submit('submit', 'Log in', 'class="btn btn-primary"'); ?></td>
        </tr>
    </table>
    <?php echo form_close(); ?>
  </div>

Answer 1

您正在使用该模型，因此您应该将语法更改为以下内容：

$this->db->get('*')
->where('email', $email)->where('password', $password);

如果你想调用这个函数，你应该在模型类中定义它并将它添加到它自己的类中。

Answer 2

在user_m.php模式文件中更改此行：

class User_m extends CI_Model{

到

class User_m extends MY_Model

致命错误：在第10行的C：\ xampp \ htdocs \ cms \ application \ controllers \ admin \ user.php中调用未定义的方法User_m :: get_by（）
