描述了如何将数据从表单传递到控制器

Question

我试图将数据从HTML表单传递到控制器，但当我使用dd函数时，它不显示我来自HTML的任何输入值，它与具有相同控制器的另一个HTML页面一起工作我的控制器

public function carEdit(Request $request, Cars $cars, $id)
{
$data = $request->input();
dd($data); //when use dd it's give me 
// array:1 [▼
//  "_token" => "UE36YHG6TF1HnGsAkLFJAOFsrACZ8pmL3Ya9iFHE"
//]
// I think it should show me the input values in the form like this:
// array:1 [▼
// 'title'
// 'content'
// 'youtube'
// ...etc]
$cars = DB::table('cars')->where('id',$id)->get();
$car = Cars::findOrFail($id);
// $car->title = $data['title'];
// $car->content = $data['content'];
// $car->youtubevid = $data['youtubevid'];
// $car->bannerimage = $data['bannerimage'];
// $car->extrainfo = $data['extrainfo'];
// $car->location = $data['location'];
// $car->car_price = $data['car_price'];
$car->update();
return view('/dashboard/editCars')->with('cars',$cars);
} 

HTML代码

@extends('dashboard.base')
@section('content')
<div class="container-fluid">
<div class="fade-in">

您将Id作为静态传递。我认为最好的方法就是

<form method="post" action="/cars/$variableYouWantToPassHere/edit" 
enctype="multipart/form-data" >
public function carEdit(Request $request, $id){
$data = $request->all();
dd($data);//when use dd it's give me 
}

then in your route

Route::POST('/cars/{id}/edit','YOURCONTROLLER@carEdit');
