Laravel 5 Basics (8) - Basic Process of Model, Controller, and View

• Add route

<code>Route::get('artiles', 'ArticlesController@index');</code>

• Create Controller

<code> php artisan make:controller ArticlesController --plain</code>

• Modify controller

<code><?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;
    }

}</code>

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

Modify the controller and return to the view

<code>	public function index() {
        $articles = Article::all();

        return view(&#39;articles.index&#39;, compact(&#39;articles&#39;));
    }</code>

Create View

<code>@extends(&#39;layout&#39;)

@section(&#39;content&#39;)
    <h1>Articles</h1>

    @foreach($articles as $article)
        <article>
            <h2>{{$article->title}}</h2>

            <div class="body">{{$article->body}}</div>
        </article>
    @endforeach
@stop</code>

Browse the results, COOL! ! ! !

• Show single post

Add route showing details

<code>Route::get('articles/{id}', 'ArticlesController@show');</code>

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

<code>    public function show($id) {
        $article = Article::find($id);

        //若果找不到文章
        if (is_null($article))
        {
            //生产环境 APP_DEBUG=false
            abort(404);
        }
        return view('articles.show', compact('article'));
    }</code>

Laravel provides more convenient functions to modify the controller:

<code>    public function show($id) {
        $article = Article::findOrFail($id);

        return view('articles.show', compact('article'));
    }</code>

It's cool.

New View

<code>@extends('layout')

@section('content')
    <h1>{{$article->title}}</h1>

    <article>
        {{$article->body}}
    </article>
@stop</code>

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

Modify index view

<code>@extends('layout')

@section('content')
    <h1>Articles</h1>
    <hr/>
    @foreach($articles as $article)
        <article>
            <h2>
                {{--这种方式可以--}}
                <a href="/articles/{{$article->id}}">{{$article->title}}</a>
                {{--这种方式更加灵活，不限制路径--}}<br>
                <a href="{{action(&#39;ArticlesController@show&#39;, [$article->id])}}">{{$article->title}}</a>
                {{--还可以使用--}}<br>
                <a href="{{url(&#39;/articles&#39;, $article->id)}}">{{$article->title}}</a>
            </h2>

            <div class="body">{{$article->body}}</div>
        </article>
    @endforeach
@stop</code>

The above introduces the basics of Laravel 5 (8) - the basic process of model, controller and view, including the content. I hope it will be helpful to friends who are interested in PHP tutorials.
