if I have url rules like this
<module>/<controller>/<action>
how i can extends as controller?
real example
i want to make route like this:
hxxp://s*te.com/admin/company/user/create
hxxp://s*te.com/<module>/<controller>/<action>/???
if you see, 'user' is a action from 'company' controller
I want to make user become a controller, so 'create' will be an action function
is possible?
'<module:[\w\-]+>/<controller:[\w\-]+>/<user_id:\d+>/<action:[\w\-]+>' => '<module>/<controller>/<user_id>/<action>',
public function actionCreate($user_id = null){
//your statment here
}

I need to check the records in the notifications table at every page load of every controller.
So I wrote it in a component and the component is executed in the bootstraping process.
I need the notifications to be available in the layout so that i can show them in the notification menu.
below is what I have tried so far:
component:
namespace admin\components;
use Yii;
use yii\base\Component;
use admin\models\Notification;
class NotificationManager extends \yii\base\Component{
public function init() {
$notifications = Notification::find()->orderBy('id DESC')->asArray()->all();
//echo "<pre>"; print_r($notifications);exit;
if(count($notifications)>0){
foreach ($notifications as $notif) {
if($notif['type'] == 'courier')
$courier_notifications[] = $notif;
elseif($notif['type'] == 'order')
$order_notifications[] = $notif;
}
Yii::$app->view->params['courier_notifications'] = $courier_notifications;
Yii::$app->view->params['order_notifications'] = $order_notifications;
}
}
}
Layout:
$courier_notifications = $this->params['courier_notifications'];
I am not sure which part am I going wrong: in component or in the layout?
I appreciate your help.
Im not sure why your component execution during bootstrap fails to add the value to params.But believe it to be an overkill.
You can rather move the logic to component method and access in layout whenever necessary
Component.
namespace admin\components;
use Yii;
use yii\base\Component;
use admin\models\Notification;
class NotificationManager extends Component{
public function notifications($type = 'courier') {
$notifications = Notification::find()
->where(['type' => $type])
->orderBy('id DESC')
->asArray()->all();
return $notifications;
}
}
Add the component class under Components section in your config file
'notificationManager ' => [
'class' => 'admin\components\NotificationManager'
]
Layout
$courier_notifications = yii::$app->notificationManager->notifications('courier');
If you really want to go bootstrap mode, you need to implement yii\base\BootstrapInterface and put your logic in the bootstrap($app) method in order for the param to be available site-wide by setting the value of Yii::$app->params['notifications'] to the result of your logic.
Another common approach is to add a new method public function displayNotifications or whatever you want to name it, to your component, move all the logic in it and then in your layout/view etc., call it with Yii::$app->notificationManager->displayNotifications(). You can also pass additional parameters to it and enhance your logic.
notificationManager has to be replaced with the name you registered your custom component in the Yii app config (web.php for basic app, main.php for advanced app).
LE - If you only registered your component for bootstrap, you should also register it in the components array.
'notificationManager' => [
'class' => '\admin\components\NotificationManager'
]
Today i wanted to use Cakephp3 auth component.
I have studies cakephp3 blog tutorial and auth documentation.
I have followed Blog tutorial, and for now everything works fine, like login,logout etc...
I wanted to have UsersController to be protected and used only when i will logged in.
And this is ok, but now i saw that i need to login to other controllers actions, for example i have PagesController, which should be public.
I found this in docs:
// Allow only the view and index actions.
$this->Auth->allow(['view', 'index']);
But i have a lot of actions, and listing actions in this function may be problematic.
My question is: How can i globally set all actions of UsersController to be protected, and all the rest of controllers to be public ?
Thank You.
For UsersController
class UsersController extends AppController
{
public function beforeFilter(Event $event)
{
// allow only login, forgotpassword
$this->Auth->allow(['login', 'forgotpassword']);
}
}
For Other controller. (Example: PagesController)
class PagesController extends AppController
{
public function beforeFilter(Event $event)
{
// allow all action
$this->Auth->allow();
}
}
In your appsController, you can add below code. You must add all the view names in $this->Auth->allow('ViewName').
public function beforeFilter(Event $event)
{
parent::beforeFilter($event);
// Allow users to register and logout.
// You should not add the "login" action to allow list. Doing so would
// cause problems with normal functioning of AuthComponent.
$this->Auth->allow(['Index', 'View', 'Edit', 'CustomViewName']); // NOTE: DO NOT ADD VIEWS THAT ARE USED BY YOUR USERSCONTROLLER.
}
And from UsersController, you can remove $this->Auth->allow(['add', 'logout']);. This is how I would do it.
I think you can use ControllerAuthorize.It will allows you to handle authorization checks in a controller callback.Add this setting in your app component.
$this->loadComponent('Auth', [
'authorize' => 'Controller',
]);
Then you can prevent or allow access by isAuthorized()
example :
public function isAuthorized($user) {
if ( isset($user['role']) == 'yourRole' ) {
return TRUE;
}
else {
header("location: Router::url('/', true)");
exit();
}
}
For details
cake doc
Try:
$this->Auth->deny(['controllers name that you want to authorize']);
I would like to check if my user have filled certain fields in his profile before he can access any action of any controller.
For example
if(empty(field1) && empty(field2))
{
header("Location:/site/error")
}
In yii1 I could do it in protected\components\Controller.php in init() function
But in yii2 I'm not sure where to put my code. I cannot modify core files, but not sure what to do in backend of my advanced application to make it work.
I know I can user beforeAction() but I have too many controllers to do that and to keep track of every controller
In case you need to execute a code before every controller and action, you can do like below:
1 - Add a component into your components directory, for example(MyGlobalClass):
namespace app\components;
class MyGlobalClass extends \yii\base\Component{
public function init() {
echo "Hi";
parent::init();
}
}
2 - Add MyGlobalClass component into your components array in config file:
'components' => [
'MyGlobalClass'=>[
'class'=>'app\components\MyGlobalClass'
],
//other components
3 - Add MyGlobalClass into bootstarp array in config file:
'bootstrap' => ['log','MyGlobalClass'],
Now, you can see Hi before every action.
Please note that, if you do not need to use Events and Behaviors you can use \yii\base\Object instead of \yii\base\Component
Just add in config file into $config array:
'on beforeAction' => function ($event) {
echo "Hello";
},
Create a new controller
namespace backend\components;
class Controller extends \yii\web\Controller {
public function beforeAction($event)
{
..............
return parent::beforeAction($event);
}
}
All your controllers should now extend backend\components\Controller and not \yii\web\Controller. with this, you should modify every controller. I would go for this solution.
I believe you might also replace 1 class with another (so no change to any controller necessary), something like
\Yii::$classMap = array_merge(\Yii::$classMap,[
'\yii\web\Controller'=>'backend\components\Controller',
]);
See more details here: http://www.yiiframework.com/doc-2.0/guide-tutorial-yii-integration.html and I took the code from here: https://github.com/mithun12000/adminUI/blob/master/src/AdminUiBootstrap.php
you can put this in your index.php file. However, make sure you document this change very well as somebody that will come and try to debug your code will be totally confused by this.
Just i think this code on config file can help you:
'on beforeAction' => function ($event) {
// To log all request information
},
'components' => [
'response' => [
'on beforeSend' => function($event) {
// To log all response information
},
],
];
Or, https://github.com/yiisoft/yii2/blob/master/docs/guide/security-authorization.md use RBAC, to restrict access to controllers actions one at a time based on rules. Why would you want to restrict access to controller actions based on user fields is beyond me. You will not be able to access anything (including the login form) if you put a restriction there.
I'm trying to implement the following:
Simple controller and action. Action should return response of 2 types depending on the request:
HTML in case of ordinary request (text\html),
JSON in case of ajax request (application\json)
I've managed to do this via a plugin for controller, but this requres to write
return $this->myCallBackFunction($data)
in each action. And what if I wan't to do this to whole controller? Was trying to figure out how to implement it via event listener, but could not succed.
Any tips or link to some article would be appreciated!
ZF2 has the acceptable view model selector controller plugin specifically for this purpose. It will select an appropriate ViewModel based on a mapping you define by looking at the Accepts header sent by the client.
For your example, you first need to enable the JSON view strategy by adding it to your view manager config (typically in module.config.php):
'view_manager' => array(
'strategies' => array(
'ViewJsonStrategy'
)
),
(It's likely you'll already have a view_manager key in there, in which case add the 'strategies' part to your current configuration.)
Then in your controller you call the controller plugin, using your mapping as the parameter:
class IndexController extends AbstractActionController
{
protected $acceptMapping = array(
'Zend\View\Model\ViewModel' => array(
'text/html'
),
'Zend\View\Model\JsonModel' => array(
'application/json'
)
);
public function indexAction()
{
$viewModel = $this->acceptableViewModelSelector($this->acceptMapping);
return $viewModel;
}
}
This will return a normal ViewModel for standard requests, and a JsonModel for requests that accept a JSON response (i.e. AJAX requests).
Any variables you assign to the JsonModel will be shown in the JSON output.
I am creating a rest api using yii framework so the basic output format would be json....
I want all actions in a controller to have header content-type as 'application-json'.
I tried to put it in beforeFilter function in the controller but it didn't work.
Can any one help me out...
Create an init() function in the Controller class (protected/components/Controller.php). This will be called when any Controller/Action is called. Eg:
public function init(){
if ($this->id == 1){
// perform controller specific function
}
}
The $this->id returns the controller id. You must obviously replace the 1 in the code above with the relevant controller id for the controller you want the function to take place with
