Laravel创建产品-CRUD之Create and Store

　　上一篇说了laravel用crud之index列出产品items，我们现在试着添加产品，用到CRUD的 Create 和 Store 方法，打开/app/Http/Controllers/ItemController.php定义一下create和store方法

1,添加新产品

?

1 2 3 4

public function create() {     return view('items.create'); }

2,保存刚刚添加的产品到数据库　　

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

public function store(Request $request)     {         $validatedData = $request->validate([             'name' => 'required|unique:items|max:255',             'price' => 'required|numeric',             'img' => 'required|max:255',             'description' => 'required|max:255',         ]);//检查输入是否合法         //         $item = New Item;           $item->name = $request->name;         $item->price = $request->price;         $item->img = $request->img;         $item->description = $request->description;           $item->save();                  }

　　3,写create.blade.php模板，文件在/resources/views/items/create.blade.php，添加如下代码

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58

@extends('layouts.app')   @if ($errors->any())     <div class="alert alert-danger">         <strong>Errors:</strong>         <ul>             @foreach ($errors->all() as $error)                 <li>{{ $error }}</li>             @endforeach         </ul>     </div> @endif   @section('content')     <div class="container">         <div class="row">             <div class="col-md-8 col-md-offset-2">                 <div class="panel panel-default">                     <div class="panel-heading">Create New Item</div>                     <div class="panel-body">                         <form method="POST" action="/items" aria-label="Register">                             @csrf                             <div class="form-group row">                                 <label for="name" class="col-md-4 col-form-label text-md-right">Name</label>                                 <div class="col-md-6">                                     <input id="name" type="text" name="name" value="" required="required" autofocus="autofocus" class="form-control">                                 </div>                             </div>                             <div class="form-group row">                                 <label for="email" class="col-md-4 col-form-label text-md-right">Price</label>                                 <div class="col-md-6">                                     <input id="email" type="text" name="price" value="" required="required" class="form-control">                                 </div>                             </div>                             <div class="form-group row">                                 <label for="password" class="col-md-4 col-form-label text-md-right">Img</label>                                 <div class="col-md-6">                                     <input id="password" type="text" name="img" class="form-control">                                 </div>                             </div>                             <div class="form-group row">                                 <label for="password-confirm" class="col-md-4 col-form-label text-md-right">Description</label>                                 <div class="col-md-6">                                     <input id="password-confirm" type="text" name="description" required="required" class="form-control">                                 </div>                             </div>                             <div class="form-group row mb-0">                                 <div class="col-md-6 offset-md-4">                                     <button type="submit" class="btn btn-primary">Save</button>                                 </div>                             </div>                         </form>                     </div>                 </div>                </div>            </div>        </div>    @endsection
