　　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

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

2,保存刚刚添加的产品到数据库　　

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

@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>
