一、创建文章增删改成提交的控制器

1、注释文章查看权限，非登录状态可以查看文章列表页

   注释HomeController.php下//$this->middleware('auth');

修改模板文件

运行Sooma

2、创建提交控制器post

php artisan make:model Post --migration --resource

创建资源控制器（自动生成增删改查方法）和数据表

成功多了以下文件

 

3、创建数据表

增加数据表字段

更新数据表

php artisan migrate

 

4、创建提交post资源路由

Route::get('/', [App\Http\Controllers\HomeController::class, 'index'])->name( 'home');
Route::resource('/posts',App\Http\Controllers\PostController::class)->middleware('auth');

5、创建post控制器view目录post

 

二、文章添加功能实现

1.模板显示

2.复制home.blade.php模板到post下命名为create.blade.php

@extends('layouts.app')@section('content')
<div class="container"><div class="row justify-content-center"><div class="col-md-8"><h2>提交</h2>@if($errors->any())<div class="alert alert-danger"><ul>@foreach( $errors->all() as $error)<li>{{ $error }}</li>@endforeach</ul></div>@endif@if(session('success'))<div class='alert alert-success'>Updated Successfully!</div>@endif<form action="{{ route('posts.store') }}" method="post">@csrf<div class="form-group"><label for="title">标题</label><input type="text" class="form-control" id="title" name="title"></div><div class="form-group"><label for="title">内容</label><textarea  class="form-control" id="content" name="content" role="4"></textarea></div><button type="submit" class="btn btn-primary">提交</button></form></div></div>
</div>
@endsection

 3、控制器实现post

    /*** Store a newly created resource in storage.** @param  \Illuminate\Http\Request  $request* @return \Illuminate\Http\Response*/public function store(Request $request){//$request->validate(['title'=>'required','content'=>'required']);$post=new Post;$post->title=request('title');$post->content=request('content');$post->uid=\Auth::id();$post->save();return redirect()->to('/');}

三、文章修改

1、控制器显示post

  /*** Show the form for editing the specified resource.** @param  \App\Models\Post  $post* @return \Illuminate\Http\Response*/public function edit(Post $post){//return  view('post.edit',compact('post'));}

2、创建edit.blade.php模板文件

@extends('layouts.app')@section('content')
<div class="container"><div class="row justify-content-center"><div class="col-md-8"><h2>修改提交</h2>@if($errors->any())<div class="alert alert-danger"><ul>@foreach( $errors->all() as $error)<li>{{ $error }}</li>@endforeach</ul></div>@endif@if(session('success'))<div class='alert alert-success'>Updated Successfully!</div>@endif<form action="{{ route('posts.update',[$post->id]) }}" method="post">@csrf@method('put')<div class="form-group"><label for="title">标题</label><input type="text" class="form-control" id="title" name="title" value="{{ $post->title }}"></div><div class="form-group"><label for="title">内容</label><textarea  class="form-control" id="content" name="content" role="4" >{{ old('content',$post->content) }}</textarea></div><button type="submit" class="btn btn-primary">提交</button></form></div></div>
</div>
@endsection

3、文章修改保存控制器

   public function update(Request $request, Post $post){$request->validate(['title'=>'required','content'=>'required']);$post->title=request('title');$post->content=request('content');$post->uid=\Auth::id();$post->save();return redirect()->route('posts.edit',[$post->id])->with('success',true);}

四、文章列表显示

1、模板文件home.blade.php

@extends('layouts.app')@section('content')
<div class="container"><div class="row justify-content-center"><div class="col-md-8">@foreach(App\Models\Post::orderBy('created_at','DESC')->get() as $post)<div class="card"><div class="card-header">{{ $post->id }}&&{{ $post->title }}*****{{ $post->created_at }}</div><a href="{{ route('posts.edit',[$post->id] ) }}">修改</a><form action="{{ route('posts.destroy',[$post->id]) }}" method="post"><button type="submit" class="btn alert-danger"><a href="#">删除</a></button>@csrf@method('delete')</form><div class="card-body">{{ $post->content }}</div></div>@endforeach</div></div>
</div>
@endsection

五、删除文章

1、模板home.blade.php

  <form action="{{ route('posts.destroy',[$post->id]) }}" method="post"><button type="submit" class="btn alert-danger"><a href="#">删除</a></button>@csrf@method('delete')</form>

2、删除控制器post

    public function destroy(Post $post){//$post->delete();return redirect()->to('/');}
