Cakephp 2.3: Auth component, Authenticate user on two column in OR - php

Question

I am building the application using cakephp.
I have choosed the cakephp2.3.
User would be authenticated using either 'email' OR 'username'.
I found one option with Auth component "scope", but with this we can set static conditions.
LIKE: if user is active,, is_active => 1
But I want that while authenticating auth component should check either 'email' or 'username' field and other is password.
Is there any way?

Answer 1

This needs some code. You can easily find it through Users/CakeDC plugin found here
This plugin Uses the auth component below for login with multiple columns.
https://github.com/CakeDC/users/blob/master/Controller/Component/Auth/MultiColumnAuthenticate.php
It also includes an example of how to use. If you don't want the whole plugin you can just copy the MultiColumnAuthenticate.php to the folder app/Controllers/Components/Auth/.
if you copy only the file then in beforeFilter method inside your AppController you must write:
class AppController extends Controller {
public function beforeFilter() {
parent::beforeFilter();
$this->Auth->authenticate = array(
'MultiColumn' => array( //With no plugin
'fields' => array(
'username' => 'username',
'password' => 'password'
),
'columns' => array('username', 'email'),
)
);
}
}

according to cakephp documentation.
FormAuthenticate allows you to authenticate users based on form POST data. Usually this is a login form that users enter information into
By default AuthComponent uses FormAuthenticate
you can try this:
// Pass settings in $components array
public $components = array(
'Auth' => array(
'authenticate' => array(
'Form' => array(
'fields' => array('username' => 'email', 'password' => 'password')
)
)
)
);
