Basic Process of model, Controller, and view for Laravel5 framework learning-php instance

This article describes the basic processes of models, controllers, and views in the Laravel5 framework. In fact, the MVC Architecture Model divides an interactive system into three components. The model contains core functions and data. The view displays information to the user. The controller processes user input. A view and a controller constitute a user interface. 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 the 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 = false abort (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.
