php - 在laravel中获得产品ID

嗨，我正试图从表products中获取产品id，以便将其插入到wishlist表中，控制器就是这样的：

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Http\Requests;
use App\Http\Controllers\Controller;
use Auth;
use App\User;
use App\Product;
use DB;

class listController extends Controller
{
    //
    public function getCreate(){

        $list=DB::table('wishlist')->get(['id','product_id']);
        $product=Product::get(['name','id','salary','image_name']);
        $user=Auth::user()->id;
        return view('contents.wishlist')->with('list',$list)
                                        ->with('product',$product)
                                        ->with('user',$user);
    }
    public function postCreate(Request $request){
        $id=$request->input('id');
        $user_id=Auth::user()->id;
        $product_id=Product::find('id');

        DB::table('wishlist')->insert(['id'=>$id,'user_id'=>$user_id,'product_id'=>$product_id]);
        return redirect()->action('listController@postCreate');
    }
}

我可以用什么函数来得到？
显示列表的视图是：

<form id="wishlist-view-form" action="{{ action('listController@postCreate') }}" method="post">
    <fieldset>
        <input name="form_key" type="hidden" value="inYgLvzSpOOWWVoP" />
        <table class="data-table" id="wishlist-table">
            <thead>
                <tr>
                    <th></th>
                    <th>Product Details and Comment</th>
                    <th>Add to Cart</th>
                    <th></th>
                </tr>
            </thead>
            <tbody>
                @foreach($product as $p)
                    @foreach($list as $l)
                        @if($p->id == $l->product_id)
                            <tr id="item_6">
                                <td>
                                    <a class="product-image" href="product_detail" title=" {{$p->name}} "> <img src="{{asset('images/')}}/{{$p->image_name}}" width="113" height="113" alt=" {{$p->name}} " /> </a>
                                </td>
                                <td>
                                    <h3 class="product-name"><a href="product_detail" title=" {{$p->name}} "> {{$p->name}} </a></h3>

最佳答案

在html内部添加另一个输入以获取产品id

<input type="hidden" name="product_id" value="{{ $p->id }}" />

在foreach方法中，请使用以下内容：

$product_id = $request['product_id'];

//or

$product_id = Input::get('product_id');
