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('/');}
