How to set default action dynamically in Yii - yii

Question

i want to change default action of a controller depends on which user is logged in.
Ex. There are two users in my site : publisher and author and i want to set publisher action as default action when a publisher is logged in, and same for author.
what should i do? when can I check my roles and set their relevant actions?

Answer 1

Another way to do this would be setting the defaultAction property in your controller's init() method. Somewhat like this:
<?php
class MyAwesomeController extends Controller{ // or extends CController depending on your code
public function init(){
parent::init(); // no need for this call if you don't have anything in your parent init()
if(array_key_exists('RolePublisher', Yii::app()->authManager->getRoles(Yii::app()->user->id)))
$this->defaultAction='publisher'; // name of your action
else if (array_key_exists('RoleAuthor', Yii::app()->authManager->getRoles(Yii::app()->user->id)))
$this->defaultAction='author'; // name of your action
}
// ... rest of your code
}
?>
Check out CAuthManager's getRoles(), to see that the returned array will have format of 'role'=>CAuthItem object, which is why i'm checking with array_key_exists().
Incase you don't know, the action name will be only the name without the action part, for example if you have public function actionPublisher(){...} then action name should be: publisher.

Another, simpler, thing you can do is keep the default action the same, but that default action simply calls an additional action function depending on what kind of user is logged in. So for example you have the indexAction function conditionally calling this->userAction or this->publisherAction depending on the check for who is logged in.

I think you can save "first user page" in user table. And when a user is authenticated, you can load this page from database. Where you can do this? I think best place is UserIdentity class. After that, you could get this value in SiteController::actionLogin();
You can get or set "first page" value:
if (null === $user->first_page) {
$firstPage = 'site/index';
} else {
$firstPage = $user->first_page;
}
This is a complete class:
class UserIdentity extends CUserIdentity
{
private $_id;
public function authenticate()
{
$user = User::model()->findByAttributes(array('username' => $this->username));
if ($user === null) {
$this->errorCode = self::ERROR_USERNAME_INVALID;
} else if ($user->password !== $user->encrypt($this->password)) {
$this->errorCode = self::ERROR_PASSWORD_INVALID;
} else {
$this->_id = $user->id;
if (null === $user->first_page) {
$firstPage = 'site/index';
} else {
$firstPage = $user->first_page;
}
$this->errorCode = self::ERROR_NONE;
}
return !$this->errorCode;
}
public function getId()
{
return $this->_id;
}
}
/**
* Displays the login page
*/
public function actionLogin()
{
$model = new LoginForm;
// if it is ajax validation request
if (isset($_POST['ajax']) && $_POST['ajax'] === 'login-form') {
echo CActiveForm::validate($model);
Yii::app()->end();
}
// collect user input data
if (isset($_POST['LoginForm'])) {
$model->attributes = $_POST['LoginForm'];
// validate user input and redirect to the previous page if valid
if ($model->validate() && $model->login())
$this->redirect(Yii::app()->user->first_page);
}
// display the login form
$this->render('login', array('model' => $model));
}
Also, you can just write right code only in this file. In SiteController file.
