未定义变量：tabelstok.blade.php上的键-编程知识-白鹭情

在我遇到这个问题之前，我尝试将数据库从 laravel 连接到 phpmyadmin，我认为它已经解决了我不知道它是否解决了或者还没有导致错误在它说“SQLSTATE [HY000] [1045] 访问之前说不同”拒绝用户'homestead'@'localhost'（使用密码：YES）”类似的东西，在我更改了一些代码之后，我又遇到了另一个问题。

我收到一条错误讯息，例如Undefined Variable: Key from this file name tabelstok.blade.php

来自tabelstok.blade.php 的代码：

<!DOCTYPE html>
<html>
<head>
    <title>Tabelstok</title>
    <h1> Tabel Stok Master </h1>
</head>
<body>
    <table width="80%" border="1">
        <th> No </th>
        <th> Kode Barang </th>
        <th> Nama Barang </th>
        <th> Harga Barang Terakhir </th>
        <th> Id Satuan </th>

        <?php
        foreach ($ds as $key) {

        }
        ?>

        <tr>
        <td> {{$key->no}} </td>
        <td> {{$key->kode}} </td>
        <td> {{$key->nama}} </td>
        <td> {{$key->hbt}} </td>
        <td> {{$key->ids}} </td>
        </tr>
        
    </table>
</body>
</html>

这是我的控制器代码：

<?php

namespace App\Http\Controllers;

use Illuminate\Foundation\Bus\DispatchesJobs;
use Illuminate\Routing\Controller as BaseController;
use Illuminate\Foundation\Validation\ValidatesRequests;
use Illuminate\Foundation\Auth\Access\AuthorizesRequests;
use Illuminate\Support\Facades\DB;
use Illuminate\Http\Request; 

class regbcontroller extends BaseController     
{
    //class terdiri dari :
    //1. fungsi/method   atribut/data/variabel
public function fungsimenuregb(){
    return view ('regb.viewcontroller');
    }

public function fungsimenuregb2(){
    return view ('regb.viewcontroller2');
    }

public function fungsimenuparam(Request $r){
    $nil1=$r->nilai1;
    $nil2=$r->nilai2;

        return view ('regb.viewparam')
        ->with('nilaa1', $nil1)
        ->with('nilaa2', $nil2)
        ;
    }

    public function fungsitabelstok(Request $r){
        $ds=DB::table('tbbarang')
                 ->get();

        return view ('regb.tabelstok')
                 ->with('ds',$ds);

    }

public function simpantambahstok(Request $r){
    //proses simpan
    $simpan=array
    (
            'kode' => $r -> kd,
            'nama' => $r -> nama,
            'hbt' => $r -> hbt,
            'idsatuan' => $r -> ids
    );

    DB::table ('tbbarang') ->insertgetID($simpan);

    return redirect('tabelstok')
        -> with('pesan', 'profile updateSuccess');
}

}

这是我的路线代码：

<?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!

*/


//UNTUK MEMANGGIL WELCOME
Route::get('/', function () {
    return view('welcome');
});



//UNTUK MENERIMA REQUEST MENUSATU
Route::get('/menusatu', function () {
    return view('regb.halamansatu');
});

Route::get('/menudua', function () {
    return view('regb.halamandua');
});

    
Route::get('/menukontroller','regbcontroller@fungsimenuregb');

Route::get('/menukontroller2','regbcontroller@fungsimenuregb2');

Route::get('/menu/{nilai1}/{nilai2}','regbcontroller@fungsimenuparam');

Route::get('/tabelstok','regbcontroller@fungsitabelstok');

Route::get('/tambahstok','regbcontroller@formtambahstok');

Route::get('/editstok', 'regbcontroller@formeditstok');

Route::post('/simpantambahstok', 'regbcontroller@simpantambahstok');

Route::post('/simpaneditstok', 'regbcontroller@simpaneditstok');
