Code from controller:
public function actionSomeName($param){
do something here...
$this->renderPartial('_formCalculations', array(
'modelX'=>$modelX,
'modelY'=>$modelY,
));
}
I want to call that function in my view, but it won't work.
Is $this->renderPartial correct ? I think not, because it's only for views? But which function do I have to use then?
$this->renderPartial('Controllername/Somename',array("param"=>"value"));
You can't call the controller/action directly in the view.
You can user render/renderPartial. Render/renderPartial reference
a view file, not a controller action
You could put in your logic in the code as well (in your example, the "do something here..." part) but that is not good MVC!
The other alternative is to use a widget
Surly you can`t use renserPartial individually, but you can do it so:
$body = $this->renderPartial('Controllername/Somename',array("param"=>"value"),true);
In this code you have that view file`s scripts and you can use them anywhere you need.

I have this two file path:
1: /api/math/application/controllers/test.php
2: /learn/mathtek/application/controllers/Auth.php
I need to call the controller from path2(Auth) inside the controller of path1(test). Is this possible? if yes how?
Ive tried to used the redirect() function but didnt work.
Also i tried this:
require_once('/learn/mathtek/application/controllers/Auth.php');
$aObj = new a(); //create object
$aObj->custom_a(); //call function
but it still didnt work...help please ... newbie in codeigniter here
Thanks guys for the help. I ended up doing a direct post of the path using redirect function to make it work.
1: /api/math/application/controllers/test.php - codeigniter1
2: /learn/mathtek/application/controllers/Auth.php - codeigniter2
Examples:
If i want to call path(2) from path(1).
redirect('http://localhost/learn/mathtek/auth/signin'); --'signin' is a function inside 'auth' controller
thats the code inside the 'test' controller. This works in codeigniter even if its from different path of controller.
However this doesnt work for UNITY(WEBGL). Thats why i ended doing an echo and returning it back.
You can't call any other controller action/method for have output or return value in your controller action/method because it is out of rules of MVC.
But you can redirect from one controller action to another controller action and pass argument in another controller action like below:
redirect("CONTROLLER/ACTION/ARGUMENT1/ARGUMENT2");
Edit:
suppose you are in Test controller and in test_method() action of Test controller then you can put your business logic code in the method and got some output and now you want to call any other controller function(eg: Auth) for perform any other operation with that output then you can pass that output in a redirect function as below:
redirect("Auth/auth_method/ARGUMENT1/ARGUMENT2");
There is a controller :
use Phalcon\Mvc\Controller;
class ReferentielClientController extends Controller
{
public function indexAction(){
// moteur de template pour une View
$this->view->act_form = 'ReferentielClient/ajouterClient';
return $this->view->pick("client/listerClient");
}
public function ajouterClientAction(){
$this->view->action_form = 'ajouterClientExec';
return $this->view->pick("client/ajouterClient");
}
...
}
From a view I want to call the indexAction method of the controller ReferentielClientController. How to do that ?
Short answer: You can't.
You can't since indexAction is not a normal method, it's an action. Actions aren't called by anyone in the usual way that methods are, they are called with routes an url. Let me explain this a little bit further:
Using MVC, we have the following route using :
http://www.example.org/a/b/c
a is which we call module.
b is which we call controller.
And c is which we call action.
Index actions and default modules will not appear in the URL.
So, how to call functions from view? Better not to. Best way to proceed is to do everything in your controller and pass that info to the view. I.e.:
public function indexAction(){
$this->view->myInfo = $allMyInformationInOneObject;
}
And then, in the view (index.phtml):
<p>
<?php echo $this->myInfo ?>
</p>
Summary:
You don't need to call any controller function from the view, just give it that info from the controller.
Added info about redirection
OK, answering to your commentary. What you want is not to call that function but to redirect the browser to that action.
So, I'll suppose you have your route created in your router, if not, please, go to the Zend documentation about routing. It's highly recommended to create routes instead of using the URL itself.
I guess that you will not be able to use the normal redirecting using href on a button or such, so you will need to use the redirector helper. Since you are not in a controller, you are not able to use the helper by using:
$this->_helper->redirector->gotoUrl($url);
So you will need to instance the redirector like this:
$redirector = Zend_Controller_Action_HelperBroker::getStaticHelper('redirector');
$redirector->gotoUrl($url);
Being this $url, the URL given by your router, as you can read in the link above.
This can be done but I strongly recommend not to redirect from the view but from the controller. It would be good that all the logic remains in the controller.
I hope this helps!
Ok I found it : I set the href to point to the controller : Annuler
I have a view that is rendered with its controller. The function that calls the view is linked in my routes. It works fine when directly accessing the route, but obviously my controller is not included when I include it in my template.
How do I use my controller when I include my view?
I'm on Laravel 3.
Right now I have my controller :
public function get_current()
{
// $sales = ...
return View::make('sale.current')->with('sales',$sales);
}
My route (which obv only work on GET /current) :
Route::get('current', 'sale#current');
My master view
#include('sale.current')
Then my sale.current view calls $sales
#foreach($sales as $sale)
Thanks!
So this is the case when you want to call some laravel controller action from view to render another partial view. Although you can find one or another hack around it. However, please note that laravel controllers are not meant for that.
When you encounter this scenario when you want to reuse the same view again but don't want to supply all necessary data again & again in multiple controller actions, it's the time you should explore the Laravel View Composers.
Here is the official documentation link : https://laravel.com/docs/master/views#view-composers
Here is the more detailed version of it :
https://scotch.io/tutorials/sharing-data-between-views-using-laravel-view-composers
This is the standard way of achieving it without any patch work.
Your question is still unclear but I can try to help you. I did a small example with the requirements you gave. I create a route to an action controller as follows:
Route::get('test', 'TestController#test');
In TestController I define the action test as follows:
public function test()
{
return View::make('test.home')->with('data', array('hello', 'world', '!'));
}
According to your asking, you defined a view who includes content from another view (layout) and in that layout you use the data passed for the action controller. I create the views as follows:
// home.blade.php
<h1>Message</h1>
#include('test.test')
and
// test.blade.php
<?php print_r($data); ?>
When I access to "test" I can see print_r output. I don't know if that is what you are doing, but in my case works fine.
I hope that can help you.
I wanted the functionalities of view files to run in controller file also.
For example, I wanted $this->escapeHtml() which runs in view file alone to run in controller through some means like $this->...->escapeHtml()
Is this possible? Kindly help.
You need to get the ViewHelperManager and extract the EscapeHtml helper. This is a one example how to do it from the controller:
$viewHelperManager = $this->getServiceLocator()->get('ViewHelperManager');
$escapeHtml = $viewHelperManager->get('escapeHtml'); // $escapeHtml can be called as function because of its __invoke method
$escapedVal = $escapeHtml('string');
Note that it is recommended to escape and display the output in the view scripts and not in the controller.
I have a controller that is called with AJAX (sends JSON data), so I don't use a view.
I need to use a personnal view helper to format my data, but in my controller.
Is that possible ?
Or maybe I am doing it wrong (maybe I should have a view, but how with JSON) ?
You can access any ViewHelper from the Controller by
$this->view->helpername(/*params*/);
// or
$helper = $this->view->getHelper('helpername');
// or
$broker = Zend_Controller_Action_HelperBroker::getStaticHelper('ViewRenderer');
$broker->getView()->helpername(/*params*/);
See Zend: How to use a custom function from a view helper in the controller?
However, you might be right that you are doing it wrong (funny pic btw), but I cannot really tell from your question. Please refine it as to why you need to call the view helper and what it is supposed to format.
Zend_Controller_Front::getInstance()->getParam('bootstrap')->getResource('view');
Just be sure that the returned view is the view you want. Because down the line, the view may get overwritten and on the controller you have a spank new view.
And all those values you setup on the view on the action helper and the like... before the controller is kicked in? All gone with the wind!
So test before assuming that if you get a view resource. it is really the same view resource you expect, and that all your vars are still there.
You may be surprised as i was!
You can create an instance of a Helper .. this will work in Controllers, Models and everywhere you need the Helper.
eg.
// create Instance
$serverUrl_helper = new Zend_View_Helper_ServerUrl();
// get the ServerUrl
$serverUrl = $serverUrl_helper->serverUrl();
Another approach is to use the ContextSwitch or AjaxContext action-helpers. This allows you to use a view-script from which you can then call your view-helper in the standard manner.
Just use action helpers, many of view helpers are available as action helpers too.
Or directly by using Zend_Date or sprintf.
