检查用户是否不活跃，不登录

Question

我想为我的登录表单添加条件 - 如果用户尚未激活，则不要登录。我正在使用 CodeIgniter。那是我的控制器：

public function login ()
    {
            
        $this->load->model('user_model');
        $user=$this->user_model->login();
        
        $this->form_validation->set_rules('username', 'Username', 'trim|required|callback_login_check');
        $this->form_validation->set_rules('password', 'Password', 'trim|required'); 

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

            $this->index();
        }
        else 
        {
            if(count($user) > 0 )    
            {
                $this->load->library('session'); 
            
                 $data = array(
                    'username' => $user['username'],
                    'user_id' => $user['user_id'],
                    'is_logged_in' => TRUE,
                    'role_id' => $user['role_id']
                
                );
                $this->session->set_userdata($data);         
                
                redirect('index/home_page');
            }
        }
    }

我的模型是：

 public function login()
    {
        $this->db->select('*'); 
        $this->db->from('users');     
        $this->db->where('username', $this->input->post('username'));
        $this->db->where('password',sha1($this->input->post('password')));
        //$this->db->where('deactivated_at = "0000-00-00 00:00:00" OR deactivated_at IS NULL');
        
        $result=$this->db->get();
            return $result->row_array();            
    }

我已经在我的登录功能中尝试使用这个：$this->db->where('deactivated_at = "0000-00-00 00:00:00" OR deactivated_at IS NULL');，但它不起作用。如果不是活动用户，我如何进行此身份验证根本不登录？

我想说您的代码有几处错误。

首先，您试图在表单验证完成之前让用户登录。这应该在之后完成，或者我认为不需要验证？

这将是您控制器中我的登录功能版本。

function login()
{
  $this->load->model('users_model');

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

  if (!$this->form_validation->run())
  {
    $this->index(); // Show the login form..
  }
  else
  {
    // This is where we try to login the user, now the validation has    passed
    if ($user = $this->users_model->login())
    {
      // Start the session...
    }
    else
    {
      // The model returned false..
    }
  }
}

所以在表单验证通过之前，您不要转到模型。然后，在你的模型中；

function login()
{
  $where = array(
    'username' => $this->input->post('username'),
    'password' => sha1($this->input->post('password'))
  );
  // $this->db->select('*'); No need for this line
  $query = $this->db->get_where('users', $where);
  if ($query->num_rows() > 0)
  {
    // Found a match
    // Are they activated?
    if (!is_null($query->row('deactivated_at'))
    {
      // The user isn't deactivated
      return $query->row_array();
    }
    else
    {
      // The user is deactivated
      return false;
    }
  }
  else
  {
    // The username and/or password is wrong...
    return false;
  }
}

希望对您有所帮助。
