I was trying to use a inherited model, by creating a model in core/ folder, and create a newer model that extends the model in core/ folder, but then, when I try to log in, I get this error:
Severity: Notice
Message: Undefined property: CL_Login::$M_Login
Filename: controllers/CL_Login.php
Line Number: 47
The form is showed correctly, and posts to the following controller CL_Login/VerifyLogin.
I have created the following controller:
public function VerifyLogin()
{
$this->form_validation->set_rules('InputUsername', 'Username', 'required');
$this->form_validation->set_rules('InputPassword', 'Password', 'required|callback_CheckPassword');
if ($this->form_validation->run())
{
echo 'login sukses';
}
else
{
echo 'login gagal';
}
}
public function CheckPassword()
{
$output = $this->M_Login->get_login($this->input->post('InputUsername'),$this->input->post('InputPassword'));
print_r($output);
// if($output)
// {
// return true;
// }
// else
// {
// return false;
// }
}
And here's the model inside Model folder:
class M_Login extends MY_Model {
protected $table = 'ms_user';
protected $primary_key = 'user_id';
public function __construct()
{
parent::__construct();
}
public function get_login($query = NULL, $username, $password)
{
$query['where']['user_name'] = $username;
$query['where']['user_password'] = md5($password);
return $this->get($query);
}
}
And here's the model inside core folder:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

The controller receives the value from the textbox smoothly with no problem. However, I got the mentioned error above. What else should I check?
