Question

当我准备编辑表时，出现以下错误：

“此路由不支持POST方法。受支持的方法： GET，HEAD。”

<?php

Route::get('/crear',[

    'uses'=>'CarController@mostrar',

    'as'=>'cars.create'

]   

);

Route::post('/crear',[

    'uses'=>'CarController@crear',

    'as'=>'cars.crear'

]);

Route::get('/', 'CarController@casa' );

Route::post('cars/{id?}/editar', 'CarController@edit')->name('editarcar');

Route::post('cars/{id?}/editar', 'CarController@update');

Auth::routes();

Route::get('/home', 'HomeController@index')->name('home');

Route::resource('cars', 'CarController');

可见

@extends('layouts.app')

@section('title', 'Contact')

@section('content')

    <div class="container col-md-8 col-md-offset-2">

        <div class="well well bs-component">

        return redirect(action('CarsController@edit', $car->id))->with('status', 'El car ' . $id . ' ha sido actualizado');

    }

Answer 1

更新控制器>使用正确的变量compact来编辑动作。

public function edit($id)
{
    $car = car::whereid($id)->firstOrFail();

    return view('edit', compact('car'));

}

添加一个{{ route("cars.update", ['car' => $car->id]) }}之类的表单操作，以便您的视图如下：

@extends('layouts.app')

@section('title', 'Contact')

@section('content')

    <div class="container col-md-8 col-md-offset-2">

        <div class="well well bs-component">

            <form class="form-horizontal" action="{{ route("cars.update") }}" method="post">

                @foreach ($errors->all() as $error)

                    <div class="alert alert-danger">{{ $error }}</div>

                @endforeach

                @if(session('status'))

                    <div class="alert alert-success">

                        {{ session('status') }}

                    </div>

                @endif

                {!! csrf_field() !!}

                <fieldset>

                    <legend>Editar </legend>

                    <div class="form-group">

                        <label for="patente" class="col-lg-label">patente</label>
