I have an ajax method which sends data to one of my controller but the method inside of my controller is not getting fired. Everytime the first method is getting executed on call. The controller looks as it follows
class TieraerzteControllerUploader extends JController
{
/**
* display task
*
* #return void
*/
function display($cachable = false)
{
require_once JPATH_COMPONENT_ADMINISTRATOR.'/helpers/upload.php';
$upload_handler = new UploadHandler();
//this one is going to be outputed
die();
}
public function locator(){
// I wait here for a dump, but is not happening
var_dump('test');
die();
echo '{"text":"John Smith","id":"433"},{"text":"Paul Sparks","id":"434"}';
}
}
I call the controller with the following url
/administrator/index.php?option=com_tieraerzte&task=uploader.locator&tmpl=component&q=search
even if I call the above url the result is the same
I think you are using wrong formated joomla url.
Try this url formate,u may call the controller
index.php?option=com_tieraerzte&view=uploader&tmpl=component&q=search
watch the difference between your url and my url.

I searched more time to find how to get the controller method name by passing the URL but not found my expected answer. I want to make a method where I will pass a URL and it will give the corresponding controller action like as below but I can't figure out.
I found a helper which just return the current URL's action which is Route::currentRouteAction()
If a route in my application like as Route::get('/abc', 'YourController#method') which will generate the url http://example.com/abc
then how can I get the YourController#method by passing http://example.com/abc
function getAction($url){
//what will be logic?
// return like App\Controllers\MyController#method
}
I have to make a custom permission system where I need it for show and hide the menu by checking the URL of each menu.
Within your controller you can do the following:
<?php
use Illuminate\Routing\Router;
use Illuminate\Http\Request;
public function index(Request $request, Router $route)
{
$action = $router->getRoutes()->match($request)->getActionName();
// action should be what you're looking for.
}
You can try this if you want to:
Route::get('/the/url', 'YourController#method');
Every time anything calls the URL in the route, your method will be called.
You don't need to navigate to that url to call your method, it could be called by a form action, or a buttons action and just execute your method.
Edit:
url is your url as parameter (plain route)
import this:
use Illuminate\Routing\Route;
this is your function:
public function method(Route $route, $url)
{
$routes = \Route::getRoutes()->getRoutes();
foreach($routes as $r){
if($r->getUri() == $url){
$youraction= $r->getActionName();
dd($youraction);
}
else{
dd('does not exist');
}
}
}
Tested.
In the header section of my website I want to show new message. I have a method that fetches new methods and return them. The problem is that header section is in thelayout section and I don't want to repeat one method in all of my controllers.
How to achieve this by not copying the method to all of my controllers? I want to trigger newMessages() method on every page request to gather new messages for logged in user. How to do this the right way?
In your controller overwrite the oOntroller class function beforeAction()
protected function beforeAction($event)
{
$someResult = doSomething()
if ($someResult == $someValue)
{
return true;
}
else
{
return true;
}
}
The return value can be used to stop the request dead in its tracks. So if it returns false, the controller action is not called, and vice versa().

You can use import controller in another controller action. something like below
class AnotherController extends Controller
{
public function actionIndex()
{
Yii::import('application.controllers.admin.YourController'); // YourController is another controller in admin controller folder
echo YourController::test(); // test is action in YourController
}
}
I'm trying to develop a package, so I've followed this tutorial until Creating a Facade section because I don't need a facade.
The problem is:
/app/routes.php
Route::get('test', 'Aristona\Installer\Installer#install');
throws an exception: Call to undefined method Aristona\Installer\Installer::callAction()
My Installer.php is like this:
workbench/aristona/installer/src/Aristona/Installer/Installer.php
<?php namespace Aristona\Installer;
class Installer
{
public static function install()
{
return "Hello";
}
}
The class is loading. I've added it to my service providers list. Also I can confirm it is loading by adding one more install method, because PHP throws a fatal error about redeclaring same method twice.
I've tried different combinations on my method prefixes (e.g without static) Doesn't solve.
Anyone know what am I doing wrong?
Your getting an error because you're trying to use routing to controller where none exists. To be more specific, Laravel is trying to perform this method from it's core Controller class:
/**
* Execute an action on the controller.
*
* #param string $method
* #param array $parameters
* #return \Symfony\Component\HttpFoundation\Response
*/
public function callAction($method, $parameters)
{
$this->setupLayout();
$response = call_user_func_array(array($this, $method), $parameters);
// If no response is returned from the controller action and a layout is being
// used we will assume we want to just return the layout view as any nested
// views were probably bound on this view during this controller actions.
if (is_null($response) && ! is_null($this->layout))
{
$response = $this->layout;
}
return $response;
}
So unless the class you're specifying in Route::get() is extending either BaseController or Controller, this exception will be thrown. If you tested the same method inside a closure, it would work.
More about Laravel controller routing can be found here.
To fix this, you should either add a controller to your package or use the Installer class inside another controller.
I'm trying to generate ajax specific responses from my controllers by using the Request::ajax() method, which is working just fine. The only problem is that the way I have it set up right now isn't really a nice looking solution.
My controller:
class HomeController extends BaseController {
protected $layout = 'layouts/main';
public function __construct()
{
$this->beforeFilter('auth');
}
public function getIndex()
{
$view = View::make('content.home.index');
if(Request::ajax()) return $view; //For ajax calls we only want to return the content to be placed inside our container, without the layout
$this->layout->menu = 'content.menu';
$this->layout->content = $view;
}
}
So right now, for every method I define within my controllers I need to add the code snippet that checks for an AJAX request and returns a single view if the statement returns true.
This leads to my question that is probably more PHP related than it is to the framework;
Is there a way of executing my AJAX check on every method call, without actually placing it inside the method? Or is there some other solution to keep my code DRY?
Thanks in advance!
PS: This is my first post on stackoverflow, so feel free to correct me if I made any mistakes
Create a new barebone layout named 'layouts/ajax' (or any name you like).
<?php echo $content ?>
In your Base controller, override this setupLayout() function.
protected function setupLayout()
{
if ( ! is_null($this->layout))
{
$layout = Request::ajax() ? 'layouts/ajax' : $this->layout;
$this->layout = View::make($layout);
}
}
Change your getIndex() function to this.
public function getIndex()
{
$view = View::make('content.home.index');
$this->layout->menu = 'content.menu';
$this->layout->content = $view;
}
Now non-ajax requests will be rendered using layout set in the controller, where as ajax requests will receive whatever set to $this->layout->content.
Note : Controller will neglect the layout setup in setupLayout(), if the called method returns truthy value. So this method will not work for functions like below.
public function getIndex()
{
return View::make('content.home.index');
}
You could just change the layout property, in the constructor, if it's an ajax request:
public function __construct()
{
$this->beforeFilter('auth');
if(Request::ajax()) {
$this->layout = '';
}
}
If it doesn't work try setting it to NULL instead.
Why would you return a VIEW via ajax? Are you using it to create a SPA? If so there are better ways. I'm generally against returning HTML via AJAX.
The route I'd go in your position is probably opposite of how you're doing it. Render the view no matter what, if the request is ajax, pass the extra data back and have JS render the data on the page. That's essentially how most Javascript MVC frameworks function.
Sorry if I am totally missing the point here, just going on an assumption of your end goal with the info you provided.
I'm returning data from Controller like this:
/**
* Password request sent
*
* #return array
*/
public function passwordRequestSentAction ()
{
return array(
'foo' => $this->bar,
);
}
But $this->foo is null within layout.phtml even though its correct within controller/passwordRequestSent.phtml
I had to create postDispatch method in my abstract controller and link to it in attachDefaultListeners() and do this in postDispatch:
$e->getViewModel()->setVariables($e->getResult()->getVariables());
Is that really the way to go? I simply want to share all my variables across, no matter if its layout or page template.
You can access the layout-template by calling $this->layout():
class MyController extends AbstractActionController
{
public function myAction()
{
$layout = $this->layout();
// Returns the ViewModel of the Layout
}
}
For more information & samples check the manual's examples.
However in most cases I'd suggest writing a viewhelper for these tasks - especially for navigation/... This encapsulates the controller's logic from viewing tasks like I want the navigation displayed here or Show me the user's login box. Same goes for almost every type of status messages.
