Add route

The Code is as follows:

Route: get ('arties', 'articlescontroller @ Index ');

Create a controller

The Code is as follows:

Php artisan make: controller ArticlesController -- plain

Modify Controller

<? Php namespace App \ Http \ Controllers; use App \ Article; use App \ Http \ Requests; use App \ Http \ Controllers \ Controller; use Illuminate \ Http \ Request; class ArticlesController extends Controller {public function index () {$ articles = Article: all (); return $ articles ;}}

You can see the returned JSON result in the browser, cool!

Modify the controller and return to the view

Public function index () {$ articles = Article: all (); return view ('articles. Index', compact ('articles '));}

Create View

@ Extends ('layout ') @ section ('content') Articles @ foreach ($ articles as $ article) {{$ article-> title }}

{$ Article-> body }}

@ Endforeach @ stop

Browsing result, COOL !!!!

Show a single article

Add a route that displays detailed information

The Code is as follows:

Route: get ('articles/{id} ', 'articlescontroller @ show ');

Here, {id} is a parameter, indicating the id of the article to be displayed. Modify the controller:

Public function show ($ id) {$ article = Article: find ($ id); // if the document cannot be found if (is_null ($ article )) {// production environment APP_DEBUG = falseabort (404);} return view ('articles. show ', compact ('Article '));}

Laravel provides more convenient functions to modify the controller:

Public function show ($ id) {$ article = Article: findOrFail ($ id); return view ('articles. show', compact ('Article '));}

It's cool.

Create View

@ Extends ('layout ') @ section ('content') {$ article-> title }}{{ $ article-> body }}@ Stop

Try to access:/articles/1/articles/2 in the browser

Modify index View

@ Extends ('layout ') @ section ('content') Articles

@ Foreach ($ articles as $ article) {-- this method can be --} id} ">{{ $ article-> title }{{ -- this method is more flexible, unlimited path --}}
Id]) }}" >{{ $ article-> title }}{{ -- you can also use --}}
Id) }}" >{{ $ article-> title }}

{$ Article-> body }}

@ Endforeach @ stop

The above is all the content of this article, hoping to help you learn the Laravel5 framework.
