从网址获取id

Question

如何获取通过url传递的id并将其保存在输入中？控制器是这样的：

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Http\Requests;
use App\Http\Controllers\Controller;
use URL;
use DB;

class productController extends Controller
{
    //
    public function getIndex(){
        $in=URL::get('id');
        $product=DB::table('products')->get(['id','name','salary','sale','p_salary','n_salary','best','type','image_name','category_id','sub_id','incategory_id','new']);
        return view('contents.products')->with('product',$product)
                                        ->with('in',$in);

    }
}

，视图就是这样：

@extends('master')
@section('content')
<form method="POST" action="{{action('productController@getIndex')}}" enctype="multipart/form-code">
{!! csrf_field() !!}
<div class="em-wrapper-main">
    <div class="container container-main">
        <div class="em-inner-main">
            <div class="em-wrapper-area02"></div>
            <div class="em-wrapper-area03"></div>
            <div class="em-wrapper-area04"></div>
            <div class="em-main-container em-col1-layout">
                <div class="row">

此外，您可以<?php namespace App\Http\Controllers; use Illuminate\Http\Request; use App\Http\Requests; use App\Http\Controllers\Controller; use Request; use DB; class productController extends Controller { public function getIndex() { $in=Request::get('id'); $product=DB::table('products')->where('incategory_id', $in)->get(['id','name','salary','sale','p_salary','n_salary','best','type','image_name','category_id','sub_id','incategory_id','new']); return view('contents.products')->with('product',$product); } } type-hint：

Illuminate\Http\Request
