How to change Yii Error Handler on the fly? - php

In Yii's config.php we have this statement which declares which Controller is the default and only-one Error-Handler within the application:
'errorHandler' => array(
'errorAction' => 'site/error',
),
So, I need to have an actionError() under my SiteController, to get the errors previewed in my site, but this is not what I really need.
I am trying to change the Yii::app()->errorHandler->errorAction on the fly, throughout my custom-controllers who extend the base CController (Yii's base controller).
Till now, I have tried something like this:
<?php
class AdminController extends CController {
public $layout = '//layouts/admin';
public function init() {
parent::init();
Yii::app()->errorHandler->errorAction = '/admin/error';
}
}
But gives no results, nor hope. Note that I also have this URL configuration:
'/admin' => '/admin/home',
'/admin/<controller:\w+>' => '/admin/<controller>',
'/admin/<controller:\w+>/<action:\w+>/<id:\d+>' => '/admin/<controller>/<action>',
'/admin/<controller:\w+>/<action:\w+>' => '/admin/<controller>/<action>',
And this means I have a whole Controllers-Views group named admin, and they are stored in following directories:
protected/controllers/admin
protected/views/admin
So by that logic, I have ErrorController in both: admin and controllers root, and by the same structure in the views directory.
That's what I have tried, and I really appreciate help, so thank you all in advance!

You should try this :
Yii::app()->setComponents(array(
'errorHandler'=>array(
'errorAction'=>'/admin/error'
)
));

execute global function automatically on running controller in yii2

We have web pages, where user will be redirected to $this->goHome(), if the session timeouts or user logouts. We have to destroy the all the session so, we have to add a function with destroying session. This function should be executed before running any action/controller in Yii2 i.e. similar to hooks in codeigniter. We have tried a helper function with destroying session and we have called the function as HomeHelper::getHelpDocUrlForCurrentPage(); in main.php layout, but the layout will be executed after running action in controller, it should work on running any controller as we have 100+ controllers. How this can be achieved, please suggest us in right way. Thanks in advance.
in
config/main.php
you could try using 'on beforeAction'
return [
'vendorPath' => dirname(dirname(__DIR__)) . '/vendor',
'bootstrap' => [
'log',
....
],
'on beforeAction' => function($event){
// your code ..
} ,
'modules' => [
....
],
...
];
While #ScaisEdge solution would work I believe application config is not proper place to hold application logic.
You should use filters to achieve result you want.
First you need to implement filter with your logic. For example like this:
namespace app\components\filters;
class MyFilter extends yii\base\ActionFilter
{
public function beforeAction() {
// ... your logic ...
// beforeAction method should return bool value.
// If returned value is false the action is not run
return true;
}
}
Then you want to attach this filter as any other behavior to any controller you want to apply this filter on. Or you can attach the filter to application if you want to apply it for each action/controller. You can do that in application config:
return [
'as myFilter1' => \app\components\filters\MyFilter::class,
// ... other configurations ...
];
You might also take a look at existing core filters if some of them can help you.

How to use cakephp classes like cakelog in external script

I have a php script in webroot folder and i want to use CakeLog::write inside it.
Is there anyway to include cakephp classes in this kind of scripts?
I know that i can bring my script to some controller action but I want to know is there anyway to use cakephp classes outside of it?
after a month it seems that there is no answer for this question.
for solving my problem I wrote my own CakeLog class with write method:
my CakeLog config in bootstrap.php:
CakeLog::config("default", array(
'engine' => 'Syslog',
'prefix' => 'tgui',
'flag' => LOG_ODELAY | LOG_PID,
'facility' => LOG_LOCAL0
));
so my custom class will be following:
class CakeLog {
public static function write($type, $msg) {
openlog("tgui", LOG_ODELAY | LOG_PID, LOG_LOCAL0);
syslog($type, $msg);
closelog();
}
}

Phalcon router doesn't react to subfolders and namespace declaration

So I've been reading a ton of stackoverflow and phalcon forum threads.. (I'm starting to hate this framework), but nothing seem to work and it doesn't explain why like Laravel does, for example.
I'm just trying to be able to operate with this application structure:
As you can see, all I want is to use namespaced controllers in subfolders to make more order for my code.
According to all explanations, here's my loader.php:
<?php
$loader = new \Phalcon\Loader();
/**
* We're a registering a set of directories taken from the configuration file
*/
$loader->registerDirs(
array(
$config->application->controllersDir,
$config->application->modelsDir,
$config->application->pluginsDir
)
)->register();
AFAIK, Phalcon should traverse all subfolders for not found classes when used via registerDirs.
Then I define my routes to specific controller after the main route to index controllers in base directory:
<?php
$router = new Phalcon\Mvc\Router(false);
$router->add('/:controller/:action/:params', array(
'namespace' => 'App\Controllers',
'controller' => 1,
'action' => 2,
'params' => 3,
));
$router->add('/:controller', array(
'namespace' => 'App\Controllers',
'controller' => 1
));
$router->add('/soccer/soccer/:controller', array(
'namespace' => 'App\Controllers\Soccer',
'controller' => 1
));
$router->add('/soccer/:controller/:action/:params', array(
'namespace' => 'App\Controllers\Soccer',
'controller' => 1,
'action' => 2,
'params' => 3
));
return $router;
And one of my controllers look like:
<?php namespace App\Controllers\Soccer;
use App\Controllers\ControllerBase as ControllerBase;
class IndexController extends ControllerBase
{
public function indexAction()
{
}
}
What's wrong here? Default top namespace is not registered? Am I missing something?
This just doesn't work. When I try to open myserver.com/soccer which I expect to go to app/controllers/soccer/IndexController.php, but instead it tells me:
SoccerController handler class cannot be loaded
Which basically means it's looking for SoccerController.php in /controllers directory and totally ignores my subfolder definition and routes.
Phalcon 1.3.0
Stuck on this for a week. Any help - Much appreciated.
I was having a problem with loading the ControllerBase and the rest of the controllers in the controllers folder using namespaces. I was having a hard time since other example projects worked fine and I realized that I was missing a small detail in the despatcher declaration where I was supposed to setDefaultNamespace
(ref: https://github.com/phalcon/vokuro/blob/master/app/config/services.php)
$di->set('dispatcher', function () {
$dispatcher = new Dispatcher();
$dispatcher->setDefaultNamespace('App\Controllers');
return $dispatcher;
});
or you can specify it directly on the routing declaration file like this
$router->add("/some-controler", array(
'namespace' => 'App\Controllers'
'controller' => 'some',
'action' => 'index'
));
that should work as well, it might be a bit confusing at first with namespaces but once you get a hang of it you will love this extremely fast framework
It looks like your namespaces have capitals
App\Controllers\Soccer
and your folder structure does not
app\controllers\soccer
In my app I have controllers with a namespace and I have just tried changing the case of the folders so they don't match and I get the missing class error.
Of course it does raise a question, how many controllers are you planning on having that namespacing them is worthwhile? Are you grouping controllers and action by function or content? I used to have loads of controllers in Zend, but now I have grouped them by function I only have 16 and I am much happier. e.g. I suspect soccer, rugby, hockey etc will probably be able to share a sport controller, articles, league positions etc will have a lot of data in common.
ps Don't give up on Phalcon! In my experience it is sooo much faster than any other PHP framework I have used it is worth putting up with a lot :)
Are you sure Phalcon traverses subfolders when registering directories to the autoloader? Have you tried adding a line to your autoloader which explicitly loads the controllers\soccer directory?
Alternatively, if your soccer controller is namespaced, you can also register the namespace: "App\Controllers\Soccer" => "controllers/soccer/" with the autoloader.

Yii actionError not handling request when error occurs

I have made my custom controller and set it as default in my main config file.
All the other actions are working fine. But when there is any error i have made :
public function actionError() {
echo 'Error'; die;
}
and then i made a not found request. It did not did the action written by me, but did default action.
Please suggest!!
If you want to use your custom error action, you have to configure the errorAction in the errorHandler application component. You can do so in your main.php. If your controller is CustomController you'd configure:
'components' => array(
// ...
'errorHandler' => array(
'errorAction' => 'custom/error',
),
// ...
You dont have to echo inside the controller.Create a view file inside your views folder and render it like so public function actionError(){ $this->render('viewName') }

Zend Framework 2.1, output from one controller action to another controller

I am using zend framework 2.1. I am trying to load the output of my indexAction from my login controller inside of my index controller. The end result I am trying accomplish is to just have my login form loaded on the index page as if it is part of that view.
I have searched for a few hours with no avail. I have attempted to use $this->view->action, which i've seen in earlier versions of zf2 but that has not worked either.
Any information would be helpful.
Taken from this blog, which explains in depth why $this->view->action() has been removed from ZF2, an example how to use the forward() (ZF2 documentation) controller plugin:
You can forward all necessary data to another controller inside your index controller action using the forward() controller plugin like this:
public function indexAction() {
$view = new ViewModel();
$login_param = $this->params('login_param');
$login = $this->forward()->dispatch('App\Controller\LoginController', array(
'action' => 'display',
'login_param' => $login_param
));
$view->addChild($login, 'login');
return $view;
}
In your view, all you need to do is:
<?php echo $this->login; ?>
Please note that the forward() plugin might return a Zend\Http\PhpEnvironment\Response instead. This happens if you use a redirect() in your login controller / action.
Also, if the Servicemanager claims to not find App\Controller\LoginController, have a look in your module.config.php. Look for a section called controllers.
Example:
[...]
'controllers' => array(
'invokables' => array(
'LoginCon' => 'App\Controller\LoginController',
'IndexCon' => 'App\Controller\IndexController',
'DataCon' => 'App\Controller\DataController',
)
),
[...]
Here, there is an alias for your login controller called LoginCon, you should use this name as controller name in the dispatch() method instead.
