Question

我有一个通过TruckController生成的资源控制器php artisan make:controller TruckController --resource。

当我转到localhost/trucks/1/edit时，编辑表单会成功显示。

当我单击提交时，我将重定向到资源显示页面（localhost/trucks/1）；但是，卡车信息不会更新，也不会引发任何错误。

似乎update函数根本没有触发，我认为这意味着我的表单中的action属性存在问题，但我不确定。路由应该没有问题，因为路由是资源控制器，因此应该已经定义了路由。

edit.blade.php

                <form method="PUT" action="{{ action('TruckController@update', ['id' => $truck->id])  }}" class="validate form-horizontal form-groups-bordered" novalidate="novalidate">
                    @csrf
                    <input type="hidden" name="state" data-geo="administrative_area_level_1" value="{{ $truck->state }}">
                    <input type="hidden" name="city" data-geo="locality" value="{{ $truck->city }}">
                    <input type="hidden" name="zipcode" data-geo="postal_code" value="{{ $truck->zipcode }}">



                    [ ... ]
                </form>

TruckController @ update

/**
     * Update the specified resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function update(TruckCreateRequest $request, Truck $truck)
    {
        $validated = $request->validated();

        $truck->name = $request->name;
        $truck->description = $request->description;
        $truck->save();
    }

TruckCreateRequest.php

<?php

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class TruckCreateRequest extends FormRequest
{
    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        return true;
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    {
        return [
            'name'              => 'required',
            'description'       => 'required',
            'city'              => 'required',
            'state'             => 'required',
            'zipcode'           => 'required',
            'address'           => 'required'
        ];
    }
}

Answer 1

从Laravel文档中：

由于HTML表单无法发出PUT，PATCH或DELETE请求，因此您将需要添加一个隐藏的_method字段来欺骗这些HTTP动词。

尝试向表单添加隐藏的方法字段：

 @method('PUT')

在此处了解更多信息：https://laravel.com/docs/5.7/blade#method-field

Answer 2

您应该尝试以下操作：

<form method="POST" action="{{ action('TruckController@update', [$truck->id])  }}" class="validate form-horizontal form-groups-bordered" novalidate="novalidate">
                    @csrf
                    <input type="hidden" name="state" data-geo="administrative_area_level_1" value="{{ $truck->state }}">
                    <input type="hidden" name="city" data-geo="locality" value="{{ $truck->city }}">
                    <input type="hidden" name="zipcode" data-geo="postal_code" value="{{ $truck->zipcode }}">
