Laravel從MySQL獲取錯誤：試圖獲取非對象的屬性

Question

我是Laravel的新手，我想製作一個使用MySQL獲取產品的小本地主機網站。

我研究並應用了一些答案後，我仍然有問題：

試圖讓非對象（查看物業： F：\ XAMPP \ htdocs中\ Laravel \資源\意見\ welcome.blade.php ）

web.php

<?php 

/* 
|-------------------------------------------------------------------------- 
| Web Routes 
|-------------------------------------------------------------------------- 
| 
| Here is where you can register web routes for your application. These 
| routes are loaded by the RouteServiceProvider within a group which 
| contains the "web" middleware group. Now create something great! 
| 
*/ 

Route::get('/', function() { 
    //return view('welcome'); 
    $products = DB::table('laravel_products')->pluck('product_name', 'product_about', 'producer_ID', 'product_added'); 
    return view('welcome', ['products' => $products]); 
}); 

welcome.blade.php

<table class="table table-striped"> 
         <thead> 
          <tr> 
           <td>Product name</td> 
           <td>Description</td> 
           <td>Date added</td> 
          </tr> 
         </thead> 
         <tbody> 
         <?php 

         foreach ($products as $value) { 
          echo ' 
           <tr> 
            <td>' . $value->product_name . '</td> 
            <td></td> 
            <td></td> 
           </tr> 
          '; 
         } 

         ?> 
         </tbody> 
        </table> 

我應該怎麼做才能從MySQL獲取？

Answer 1

你應該試試這個：

Route::get('/', function() { 
    //return view('welcome'); 
    $products = DB::table('laravel_products')->select('product_name', 'product_about', 'producer_ID', 'product_added')->get(); 
    return view('welcome', compact('products')); 
}); 


<table class="table table-striped"> 
          <thead> 
           <tr> 
            <td>Product name</td> 
            <td>Description</td> 
            <td>Date added</td> 
           </tr> 
          </thead> 
          <tbody> 
         @if(isset($products)) 
          @foreach($products as $value) 

            <tr> 
             <td> {{$value->product_name}}</td> 
             <td></td> 
             <td></td> 
            </tr> 
          @endforeach 
          @endif 
          </tbody> 
         </table> 

希望這對你的工作！
