How to implement Laravel 4 Partial Views - Binding Data to Partial Views

Question

I am discussing whether I should use Laravel to create an online store.

Demand. Show the cart in the sidebar listing the product in the main area. I need to bind data to my partial views.

I created a PartialController to display partial views.

 class PartialController extends BaseController { public function showCartSummary() { $cartItems = Cart::all(); return View::make('partials.cartsummary', array( 'cart' => $cartItems, )); } public function showProducts() { $products = Products::all(); return View::make('partials.products', array( 'products' => $products, )); } } 

I created a store index index to pull out partial views

Shop.Index.Blade.php

 @extends('master') @section('content') @include('partials.cart') @stop @section('side1') @include('partials.products') @stop 

The problem is that no data is passed to these views because partials.cart and partials.products are not called from their own controllers.

My workaround is to query the database in ShopController and pass that to the shop.index .

ShopController.php

I also created ShopController

  public function showIndex() { $cartItems = Cart::all(); $products = Product::all(); return View::make('shop.index', array( 'cartItems' => $cartItems, 'products' => $products )); } 

Of course, now I repeat my queries on db, and I don't want to repeat the same queries in every controller method that uses multiple views.

What is the best way to do this?

NB: I have more simplified database calls for the purposes of this question, and the code may have one or two typo / syntax errors, but are not important for this question.

Iteration 2:

I found that I can use view composers to create viewmodels / presenters.

shop.blade.php

 @extends('master') @section('content') @include('partials.products') @stop @section('side1') @include('partials.cartitems') @stop 

Now, to pass data to partial views: First, I turn off PartialController.php, and then change filter.php filters.php

 App::before(function($request) { View::composer('partials.products', 'ProductComposer'); View::composer('partials.cartitems', 'CartComposer'); }); class ProductComposer { public function compose($view) { $view->with('products', Product::all()); } } class CartComposer { public function compose($view) { $view->with('cartitems', Cart::all()); } } 

It's still very dirty, I don't want to fill in all my partial views in the filters.php file ... Is there a proper / official way to do this? Any examples?

Answer 1

Make the composers.php file in your app / directory and enable it through app / start / global.php. In this file, make calls to View :: composer (you do not need to put them inside App :: before).

Move the composer classes to the new app / composers / directory and add the directory to the autoloader in your composer.json.

In addition, your use of composers is correct.

Answer 2

for me create an abstract class ShopController extends BaseController

and in the constructor () write View :: composer

and you can use DB :: table ('products') → remember (100) → get (); vs all () for cache

Answer 3

You can just do

 @include('partials.products', array('data'=>'here'))
