How to login from different tables in Yii2 basic application? - yii2

Question

i have two table : Admin and Employees.
with different columns name.
how to create database login system for this scenario.
i am using Yii2 basic application.
i don't know how to deal with this problem.

Answer 1

One way out of this situation is using abstractions
E.g:
abstract class User extends ActiveRecord{
// abstract method that should overrided child classes
abstract function tableName();
}
class Admin extends User {
function tableName() { return 'admin'; }
}
class Employee extends User {
function tableName() { return 'employee'; }
}
But, it's depended on your exact situation. Also you can use setTableName() method for override only table name in the same class.

Answer 2

I agree that it's better to use some common user table. But if you still want to use 2 tables you can do that like this
<?php
namespace common\models;
use Yii;
use yii\base\Model;
/**
* Login form
*/
class LoginForm extends Model
{
public $username;
public $password;
public $rememberMe = true;
private $_user = false;
/**
* #inheritdoc
*/
public function rules()
{
return [
// username and password are both required
[['username', 'password'], 'required'],
// rememberMe must be a boolean value
['rememberMe', 'boolean'],
// password is validated by validatePassword()
['password', 'validatePassword'],
];
}
/**
* Validates the password.
* This method serves as the inline validation for password.
*/
public function validatePassword()
{
if (!$this->hasErrors()) {
$user = $this->getUser();
if (!$user) {
$this->addError('password', 'Incorrect username or password.');
return ;
}
if (!$user->validatePassword($this->password)) { // you need to implement this method for both models
$this->addError('password', 'Incorrect username or password.');
return ;
}
}
}
/**
* Logs in a user using the provided username and password.
*
* #return boolean whether the user is logged in successfully
*/
public function login()
{
if ($this->validate()) {
return Yii::$app->user->login($this->getUser(), $this->rememberMe ? 3600 * 24 * 30 : 0);
} else {
return false;
}
}
/**
* Finds user by [[username]]
*
* #return User|null
*/
public function getUser()
{
if (!$this->_user) {
$this->_user = Employee::findByUsername($this->username);
}
if (!$this->user) {
$this->_user = Admin::findByUsername($this->username);
}
return $this->_user;
}
}
