为 foreach() 提供的参数无效（查看：E:\Codes\Php\Laravel\appoint_now-master\resources\views\staff\scheduler\index.blade.php）

Question

我是 laravel 的新手。我需要帮助

当我尝试通过 compact() 方法将数据发送到索引页面时，显示错误

错误

错误异常 为 foreach() 提供的参数无效（查看：E:\Codes\Php\Laravel\appoint_now-master\resources\views\staff\scheduler\index.blade.php）

index.blade.php

 </thead>
                <tbody>
               @foreach($schedules as $s)
                    <tr>
                        <td>{{ $s->name }}</td>
                        <td>{{ $s->created_at }}</td>
                        <td>
                            <div class="btn-group btn-block">
                                <a href="{{ route('staff.scheduler.edit', $s->id) }}" class="btn btn-primary" title="@lang('messages.edit')">
                                    <i class="fa fa-edit fa-fw"></i> @lang('messages.edit')
                                </a>
                            </div>
                        </td>
                    </tr>
                @endforeach
                </tbody>

控制器

public function index()
{
    $user = auth()->guard(GuardType::STAFF)->user();
    $schedules=StaffSchedules::where('staff_id','=',$user->id)->first();
    //dd($schedules);

    return view('staff.scheduler.index',compact('schedules'));
}

路线

 Route::prefix('businessStaffMember')->name('businessStaffMember.')->middleware([GuardType::BUSINESS])->group(function(){
    Route::get('/', [BusinessBusinessStaffMemberController::class, 'index'])->name('index');
    Route::get('/create', [BusinessBusinessStaffMemberController::class, 'create'])->name('create');
    Route::get('/{businessStaffMember}/edit', [BusinessBusinessStaffMemberController::class, 'edit'])->name('edit');
    Route::post('/', [BusinessBusinessStaffMemberController::class, 'store'])->name('store');
    Route::patch('/{businessStaffMember}', [BusinessBusinessStaffMemberController::class, 'update'])->name('update');
});

Answer 1

你的问题在这里：

$schedules=StaffSchedules::where('staff_id','=',$user->id)->first();

first() 返回对象

而@foreach 需要数组！！

注意：如果你想在 foreach 中渲染对象，你应该实现迭代器接口，就像我们在下面的 commnets 中的朋友所说的那样

将其更改为以下代码，然后重试：

$schedules=StaffSchedules::where('staff_id','=',$user->id)->get();
