检查用户是否不活跃,不登录 [英] Check if user is not active, not to log in
问题描述
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:
I want to add condition for my login form - if a user is not already active, not to log in. I'm using CodeIgniter. That's my controller:
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');
}
}
}
我的模特是:
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 $result->row_array();
}
我在登录功能中尝试过此操作:$this->db->where('deactivated_at = "0000-00-00 00:00:00" OR deactivated_at IS NULL');
,但是它不起作用.如果不是活动用户,该如何进行身份验证,根本不登录?
I have tried with this: $this->db->where('deactivated_at = "0000-00-00 00:00:00" OR deactivated_at IS NULL');
in my login function, but it does not work. How could I make this authentication, if not active user, not to log in at all?
推荐答案
我的代码中有几句话是错误的.
There's a few things I would say is wrong with your code.
首先,您要在表单验证完成之前尝试登录用户.应该在之后执行此操作,否则我看不到需要验证吗?
First off, you're trying to login the user before the form validation has completed. This should be done afterwards, or I don't see the need for validation?
这是我在控制器中的登录功能版本.
This would be my version of your login function, within your controller.
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..
}
}
}
因此,在通过表单验证之前,您无需进入模型.然后,在您的模型中;
So you don't go to the model, until the form validation has passed. Then, in your model;
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;
}
}
希望这会有所帮助.
