I have a blade template called 'main' and I wonder how I can render a sub template by calling a controllers method in my main template. Lets say I have a Controller WidgetsController with a method getSubView. The method returns a specific view with some data from (for instance) a database.
I already tried to #include a template but this will not call the controller which sets some necessary data to the view.
Thanks.
views don't call services, they only take variables and put them on screen for presentation.
you're on the good side with #include(). you only need to gather the infos for that sub view beforehand in the controller, and pass it to the View::make('main')->with($vars).
you may also consider using another <?= View::make('subview')->with($vars->sub);?> within the the view. or just use the #extend functionality.
I don't entirely understand your question.
I think what you are looking for is a View Composer
It allows you to get data for a subview without having to create the data in every controller.

I'm trying to implement mvc design pattern to my existing dating-web-app project. I believe I understood the concepts and created a login model and controller without any problems. Basically, I have a base controller which initiates a view object on construct. Than I use that object to send information to the view from within the controllers as method parameters. However, I couldn't decide how to send variables to the top menu view. Since this menu displays dynamic information (request count, notification count,etc) and included in every page of the application, only two options come to my mind:
Send information to the view from every controller, which seemed like reuse of code.
Put a seperate action in the base controller and make it called automatically when other controllers extend base controller.
Which one should I choose? Or, is there a better way to do this?
how I can call an action from the view of another action, knowing that the 2 actions are belong to the same controller ?
the controller is named FilesController, and the requested action is named Subscribing.
Actions shouldn't really be called from within the view. The view should only have data fed into it that will be represented by the view code itself. Views can, however, call other views. You may want to look at how your logic is structured to see if there's a different way to go about doing this.
There is one way, though, and that's via ajax. You can make an ajax call via Javascript/jQuery to a controller, and then have that controller send back a view, which is then placed into a specific area of the original view file.
I can't figure out how to solve this problem i'm facing. Alright, so basically i have a default view/site/index.php view file which is generating the home page. Now i have built two separated Models and their associated Controllers and views. I want to include those view of the controllers in the default home page view i.e. views/site/index.php. Does it make any sense ?
So my home page is divided into several sections. The header and footer parts are the same throughout the whole site, which is why i've written them in the /themes/brushed/layouts folder under separate files. Those are being loaded fine.
The two controller i was talking about are named as FrontPageCategoriesController.php and TopProductsController.php. They are generating their separate view files i.e. index.php in their respective view folders.
How will i include those view files (index.php) into the main site view file (views/site/index.php). I just can't include those files using include_once() because the data is being generated yet by its controller. So whats the way to achieve this ?
Can anyone please help me out with this. Thanks in advance.
First you should move data generation from controller to model. Controller should only wire your input parameters to model and pass it to view. The reason is that you want to reuse models, not controllers. Remember that controller is bound to page request, while model is not.
Then just use your model to fetch the data and renderPartial to render the data. For example:
$categories = FrontPageCategories::model()->findAll();
$this->renderPartial('/frontPageCategories/index', array(
'categories' => $categories,
));
In fact it is possible to fetch categories from model directly in view, if they are not dependant on some parameters in the current page.
Actually, you should use renderPartial for your header and footer too.
Well, I've read this tutorial if I could say: http://www.symfony-project.org/book/1_1/02-Exploring-Symfony-s-Code
And, actually, I write my code very similiary. But my question, where should I insert my jQuery code? I am sure it should be in the part of the View, but are there any good examples on how should I combine it to make "live" websites?
Edit: By saying live, I mean, for example, send POST request through Ajax and get information and similar. So, no refreshes for people.
Thank you.
jQuery as a part of javascript resources should be included in html.head or in-place, depending on what should jquery do and if the code is reusable for more views.
So it has to be part of View and you're choice is to set it up in layout or action view itself
If you need the javascript on every page then add it to your master view if not then just include it to the particular view files.
In context to codeigniter:
I extend the controller with MY_Controller and initialize a property as array which would hold the scripts that are added dynamically to the view.
eg.
var $templateData['scripts'] = array();
The controllers then pass $this->templateData to the views
And the views load the extra scripts( available as $scripts) as directed by the controllers in the head tag
This way you can even avoid loading the main jquery file when not needed.
Loading jquery.js only for the controller that need it.
I am facing a problem in zend-framework related to layout. Here I have to pass some values to the layout that will be used to display the top-ranking users of the site.
Since I am new to zend-framework, I'm not able to find any way to do so.
If you have any code, idea or link, please provide me.....
Thanks in advance...........
Create a Controller Plugin that fetches this data anytime before the layout is rendered and pass the data to to the view. Then render that data on your layout.phtml like you would render any other data, e.g. use a ViewHelper or a Partial.
See http://zendframework.com/manual/en/zend.controller.plugins.html
Or use an Action Helper as explained at
http://weierophinney.net/matthew/archives/246-Using-Action-Helpers-To-Implement-Re-Usable-Widgets.html
The layout in Zend Framework is just an other view. We could define the layout as the "outer view" and the view associated with a controller action as the "inner view". To send data to the layout from a controller you can simply like this
From the controller
$this->view->someData = $data
From the layout
$this->someData
