Php 在laravel中定义全局变量时如何升级？

我有一个这样的滑块组表，我现在就在这个页面上，或者在地址中<代码>http://localhost:8000/admin/slider-组

当我点击这个

+

时，它会将我重定向到这个地址

http://localhost:8000/admin/slider-组/1/滑块

或在这些表中

web.php

Route::resource('admin/slider-groups', 'Admin\SliderGroupController');
Route::prefix('admin/slider-groups/{sliderGroup}')->group(function(){
    Route::resource('admin/sliders', 'Admin\SliderController');
});

SliderGroupController.php

public function index(Request $request)
{
    $sliderGroups = SliderGroup::all();
    return view('admin.groups.index', compact('sliderGroups'));
}

public function edit($sliderGroupId,Slider $slider)
{
    return view('admin.sliders.edit', compact('slider', 'sliderGroupId'));
}

public function update(Request $request, $sliderGroupId, Slider $slider)
{
    if ($request->hasFile('src'))
    {
        $file = $request->file('src');
        $nane = time();
        $extension = $file->getClientOriginalExtension();
        $fileName = $nane . '.' . $extension;
        $path = $file->storeAs('images/sliders', $fileName, 'public');
    }
    $data = [
        'userId' => auth()->id(),
        'groupId' => $request->groupId,
        'src' => $path,
    ];
    $slider->update($data);
    return redirect()->route('sliders.index', $sliderGroupId);
}

admin.groups.index.blade.php

@foreach($sliderGroups as $sliderGroup)
    ...
    <a href="{{ route('admin::sliders.index',   $sliderGroup->id) }}" class="mr-1">
        <i class="la la-plus text-grey text-shadow-custom font-medium-4 font-weight-normal"></i>
    </a>
@endforeach

<form method="post" action="{{ route('admin::sliders.update', [$slider->id,$sliderGroupId ]) }}" enctype="multipart/form-data">
    @csrf
    @method('PUT')
    ...

admin.sliders.edit.blade.php

@foreach($sliderGroups as $sliderGroup)
    ...
    <a href="{{ route('admin::sliders.index',   $sliderGroup->id) }}" class="mr-1">
        <i class="la la-plus text-grey text-shadow-custom font-medium-4 font-weight-normal"></i>
    </a>
@endforeach

<form method="post" action="{{ route('admin::sliders.update', [$slider->id,$sliderGroupId ]) }}" enctype="multipart/form-data">
    @csrf
    @method('PUT')
    ...

但它并没有保存我的表格
