Laravel删除产品-CRUD之delete(destroy)

　　上一篇讲了Laravel编辑产品-CRUD之edit和update，现在我们讲一下删除产品，方法和前面的几篇文章类似，照着ytkah来操作吧

　　1,controller的function destroy定义，注意这里的Name是destroy（controller的function查看方法在这），文件在/app/Http/Controllers/ItemController.php

    public function destroy($id)
    {
        $item = Item::find($id);
        $item->delete();
    }

　　2,模板的编辑，有两个地方，show.blade.php和index.blade.php，用<input type="hidden" name="_method" value="DELETE">的方法

show.blade.php模板修改

@extends('layouts.app')

@section('content')
    <div class="container">
        <div class="row">
            <div class="col-md-12">
                <div class="card">
                    <div class="card-header">Item:{{$item->id}}</div>
                    <div class="card-body">
                        <div class="col-md-8" style="float: left;">
                            <div class="form-group row">
                                <label class="col-md-2 text-md-right" >ID:</label>
                                <div class="col-md-6">{{$item->id}}</div>
                            </div>  
                            <div class="form-group row">
