I want to make some action (php script) before all actions in my frontend app and then pass a result from that script to actions in variable - so I can get variable value from all actions. Where should I declare sth like this?
If the filter solution dont feet your needs, you can also create a base action class with a preExecute function:
// app/frontend/lib/baseActions.class.php
class baseActions extends sfActions
{
public function preExecute()
{
$this->myVar = .... // define your vars...
}
}
Then your module actions class extends your baseActions class:
// app/frontend/modules/myModule/actions/actions.class.php
class myModuleActions extends baseActions
{
public function executeIndex(sfWebRequest $request)
{
// var $this->myVar is available in any action and in your template
...
}
}
if you have to use the preExecute function in your module class action, remember to call parent::preExecute() in it.
What kind of information ?
I would recommend you to use filters.
In your apps/frontend/config/filters.yml:
rendering: ~
myfilter:
class: myCustomFilter
Create the file lib/filter/myCustomFilter.php:
<?php
class myCustomFilter extends sfFilter
{
public function execute ($filterChain)
{
if ($this->isFirstCall())
{
// do what ever you want here.
$config = Doctrine_Core::getTable('Config')->findAll();
sfConfig::set('my_config', $config);
}
$filterChain->execute();
}
}
And then, every where, you can retrieve your data:
sfConfig::get('my_config');

Where do I store misc functions? How do I use them? Should it be a DependencyInjection? Should it just be a class and do I do something like use Acme\Bundle\AcmeBundle\Misc\ClientIPChecker?
Say I have a function:
<?php
class ClientIPChecker {
public static function isLocal(Request $request){
return in_array('127.0.0.1', $request->getClientIp())
}
}
And I want to use this function in two controllers. How do I do this in Symfony2?
If you have a set of consistent function put them in a class/service. If functions do different things put them in the appropriate class/service. In this particular case, I'll go for either custom Request or custom Controller (probably the latter, avoding messing app.php or app_dev.php).
With custom controller this doesn't work:
// Automatic binding of $request parameter
public function indexAction(Request $request)
{
// Won't work with custom controller
if ($request->isLocal)) {
// ...
}
// You have to do
if ($this->getRequest()->isLocal()) {
// stuff
}
}
Option 1: extend Symfony Request
namespace My\HttpFoundation;
use Symfony\Component\HttpFoundation\Request as BaseRequest;
class Request extends BaseRequest
{
public function isLocal()
{
return in_array('127.0.0.1', $this->getClientIp());
}
}
Then in web/app.php and web/app_dev.php modify:
use Symfony\Component\HttpFoundation\Request;
to be:
use My\HttpFoundation\Request;
Option 2: create a BaseAbstractController and use it instead of Symfony controller
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
abstract class BaseAbstractController extends Controller
{
public function isRequestLocal()
{
return in_array('127.0.0.1', $this->getRequest()->getClientIp())
}
}
Option 3: custom service as explained here
I want to use this code in my application:
class ControllerExtension extends Symfony\Bundle\FrameworkBundle\Controller\Controller
{
public function render($view, array $parameters = array(), Response $response = null)
{
//etc.
}
}
But where do I put it and how do i activate it? I'm guessing it's something to do with the services.yml file. I've used Event Listeners, but this is obviously different.
From your code snippet (http://justpaste.it/2caz), it seems that you missed the "return" keyword in your call to parent.
class ControllerExtension extends Symfony\Bundle\FrameworkBundle\Controller\Controller
{
public function render($view, array $parameters = array(), Response $response = null)
{
if($this->getRequest()->getRequestFormat() == 'json') {
return new Response(json_encode($parameters));
} else {
// Missing 'return' in your snippet
return parent::render($view, $parameters, $response);
}
}
}
class MyController extends ControllerExtension
{
public function indexAction()
{
// This should now work
return $this->render(...);
}
}
You can put it in your bundle's Controller directory i.e src/YourNamespace/YourBundleName/Controller/ControllerExtension.php.
Make sure you provide the appropriate namespace in that file:
namespace YourNamespace\YourBundleName\Controller;
class ControllerExtension extends Symfony\Bundle\FrameworkBundle\Controller\Controller
{
...
To use it, either create a route for it in src/YourNamespace/YourBundlename/Resources/config/routing.yml
or
extend it:
namespace YourNamespace\YourBundleName\Controller;
class OtherController extends ControllerExtension
{
...
If what you are actually looking to do is override another bundle's controller, see the cookbook which describes overriding controllers.
Edit:
As far as I know, there's no way to automatically make this controller somehow take effect. You can have each of your controllers extend it as I've indicated above.
You might be able to create an event listener and use the response event to somehow change the response if the format is json. But, I'm not sure how you would access the view data from the event listener.
I have this thing that I need in multiple places:
public function init()
{
$fbLogin = new Zend_Session_Namespace('fbLogin'); #Get Facebook Session
if(!$fbLogin->user) $this->_redirect('/'); #Logout the user
}
These two lines:
$fbLogin = new Zend_Session_Namespace('fbLogin'); #Get Facebook Session
if(!$fbLogin->user) $this->_redirect('/'); #Logout the user
Whats the best way to do it in ZendFramework?To create a plugin or? I mean I want to execute it in multiple places but If I need to edit it I want to edit it in one place.
Here is an example of an Action Helper that you can call from your controllers easily.
<?php
class My_Helper_CheckFbLogin extends Zend_Controller_Action_Helper_Abstract
{
public function direct(array $params = array())
{
// you could pass in $params as an array and use any of its values if needed
$request = $this->getRequest();
$view = $this->getActionController()->view;
$fbLogin = new Zend_Session_Namespace('fbLogin'); #Get Facebook Session
if(!$fbLogin->user) {
$this->getActionController()
->getHelper('redirector')
->gotoUrl('/'); #Logout the user
}
return true;
}
}
In order to use it, you have to tell the helper broker where it will live. Here is an example code you can put in the bootstrap to do so:
// Make sure the path to My_ is in your path, i.e. in the library folder
Zend_Loader_Autoloader::getInstance()->registerNamespace('My_');
Zend_Controller_Action_HelperBroker::addPrefix('My_Helper');
Then to use it in your controller:
public function preDispatch()
{
$this->_helper->CheckFbLogin(); // redirects if not logged in
}
It doesn't go into much detail, but Writing Your Own Helpers is helpful as well.
If you need this check in every Controller you could even set up a baseController from which you extend instead of the default one:
class My_Base_Controller extends Zend_Controller_Action
{
public function init()
{ ...
class IndexController extends My_Base_Controller
{ ...
Shift your init() into the base controller and you don't need to repeat yourself in every specific controller.
Need a varying init() in a specific controller?
class FooController extends My_Base_Controller
{
public function init()
{
parent::init();
...
Commando need's help from you.
I have a controller in Yii:
class PageController extends Controller {
public function actionSOMETHING_MAGIC($pagename) {
// Commando will to rendering,etc from here
}
}
I need some magic method under Yii CController for controlling all subrequest under /page || Page controller.
Is this somehow possible with Yii?
Thanks!
Sure there is. The easiest way is to override the missingAction method.
Here is the default implementation:
public function missingAction($actionID)
{
throw new CHttpException(404,Yii::t('yii','The system is unable to find the requested action "{action}".',
array('{action}'=>$actionID==''?$this->defaultAction:$actionID)));
}
You could simply replace it with e.g.
public function missingAction($actionID)
{
echo 'You are trying to execute action: '.$actionID;
}
In the above, $actionID is what you refer to as $pageName.
A slightly more involved but also more powerful approach would be to override the createAction method instead. Here's the default implementation:
/**
* Creates the action instance based on the action name.
* The action can be either an inline action or an object.
* The latter is created by looking up the action map specified in {#link actions}.
* #param string $actionID ID of the action. If empty, the {#link defaultAction default action} will be used.
* #return CAction the action instance, null if the action does not exist.
* #see actions
*/
public function createAction($actionID)
{
if($actionID==='')
$actionID=$this->defaultAction;
if(method_exists($this,'action'.$actionID) && strcasecmp($actionID,'s')) // we have actions method
return new CInlineAction($this,$actionID);
else
{
$action=$this->createActionFromMap($this->actions(),$actionID,$actionID);
if($action!==null && !method_exists($action,'run'))
throw new CException(Yii::t('yii', 'Action class {class} must implement the "run" method.', array('{class}'=>get_class($action))));
return $action;
}
}
Here for example, you could do something as heavy-handed as
public function createAction($actionID)
{
return new CInlineAction($this, 'commonHandler');
}
public function commonHandler()
{
// This, and only this, will now be called for *all* pages
}
Or you could do something way more elaborate, according to your requirements.
You mean CController or Controller (last one is your extended class) ?
If you extended CController class like this:
class Controller extends CController {
public function beforeAction($pagename) {
//doSomeMagicBeforeEveryPageRequest();
}
}
you could get what you need
How can i forward to other action inside the same controller avoiding repeat all dispatch proccess ?
Example:
If i point to User Controller the default action is indexAction() inside this funciton i use _forwad('list') ... but all dispatch proccess are repeated.. and i dont that
Whats is the right way ?
Usually, you will install routes to redirect your users to the proper (default) action, instead of the index action (read how to redirect from a given route using Zend_Router). But you can do everything manually if you really want to (however this is called "writing hacker code to achieve something dirty") directly from the controller.
Change your "view script" to be rendered, then call your action method....
// inside your controller...
public function indexAction() {
$this->_helper->viewRenderer('foo'); // the name of the action to render instead
$this->fooAction(); // call foo action now
}
If you tend on using this "trick" often, perhaps you may write a base controller that you extend in your application, which can simply have a method like :
abstract class My_Controller_Action extends Zend_Controller_Action {
protected function _doAction($action) {
$method = $action . 'Action';
$this->_helper->viewRenderer($action);
return $this->$method(); // yes, this is valid PHP
}
}
Then call the method from your action...
class Default_Controller extends My_Controller_Action
public function indexAction() {
if ($someCondition) {
return $this->_doAction('foo');
}
// execute normal code here for index action
}
public function fooAction() {
// foo action goes here (you may even call _doAction() again...)
}
}
NOTE : this is not the official way to do it, but it is a solution.
We Can Also use this Helper To redirect
$this->_helper->redirector->gotoSimple($action, $controller, $module, $params);
$this->_helper->redirector->gotoSimple('edit'); // Example 1
$this->_helper->redirector->gotoSimple('edit', null, null, ['id'=>1]); // Example 2 With Params
If you don't want to re-dispatch there is no reason you can't simply call the action - it's just a function.
class Default_Controller extends My_Controller_Action
{
public function indexAction()
{
return $this->realAction();
}
public function realAction()
{
// ...
}
}
You could also create a route. For example I have in my /application/config/routes.ini a section:
; rss
routes.rss.route = rss
routes.rss.defaults.controller = rss
routes.rss.defaults.action = index
routes.rssfeed.route = rss/feed
routes.rssfeed.defaults.controller = rss
routes.rssfeed.defaults.action = index
Now you only need one action and that is index action but the requess rss/feed also goes there.
public function indexAction()
{
...
}
