通过从另一个表 laravel 检索值向表添加值

Question

我目前正在为我的任务制作 web（在线商店）。 我有包含 idStore 和 idProduct 的产品表，我正在制作还包含 idStore、idProduct 和 idOrder 的订单表。 如何通过检索客户选择的 Product.idStore 和 Product.idProduct 来为 Order.idStore 和 Order.idProduct 添加值？

创建订单

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreateOrdersTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('orders', function (Blueprint $table) {  
            $table->increments('idOrder');
            $table->integer('idProduct');  
            $table->integer('idStore'); 
            $table->date('rentdate');
            $table->date('returndate');
            $table->integer('price');  
            $table->string('ship_to');
            $table->timestamps(); 
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('orders');
    }
}

OrderController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Order;
use App\Product;

class OrderController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        $orders = Order::paginate(4);
        return view('v4.index', compact('orders'));
    }

    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create($slug)
    {
        $order = Product::where('idProduct', $slug)->first()->product()->orderBy('created_at', 'DESC')->paginate(12);
        return view('v4.create', compact('order'));  
    }

    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        //
    }

    /**
     * Display the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function show($id)
    {
        //
    }

    /**
     * Show the form for editing the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function edit($id)
    {
        //
    }

    /**
     * Update the specified resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function update(Request $request, $id)
    {
        //
    }

    /**
     * Remove the specified resource from storage.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function destroy($id)
    {
        //
    }
}

请帮帮我，我必须在 5 月 19 日之前提交。 谢谢！

不确定您到底要做什么，但我想您只是想获得基于ID和StoreID的产品，您会这样做

Product::where('idProduct', $id)->where('idStore', $store)->first()

或者，如果您想自动返回 404，只需调用->firstOrFail()

仅供参考，您可能想查看如何更改您的 ID 的工作方式，通常而不是使用这个：

$table->increments('idOrder')
$table->integer('idProduct')

您将查看更合适的命名约定，例如：

$table->id()
$table->integer('product_id')

即使您正在考虑通过订单允许超过 1 个产品，我建议创建一个可以容纳篮子 session 的表，您可以使用session()->getId()来确定客户/访客和和/或者在两个orders上存储session_id ，让我们说baskets表或在baskets表上存储order_id以建立关系。

也只是为了让您知道在您的create.blade.php中，您的隐藏输入：

<input type="hidden" class="form-control" name="$order->idStore">

需要像这样包装在名称中：

<input type="hidden" class="form-control" name="{{ $order->idStore }}">
