如何从 controller class 中的 url 中获取价值

Question

这是我的路线。

Route::get('fieldequips/{hex}', Fieldequips::class,'render')->name('fieldequips');

这是我的导航

 <x-jet-dropdown-link href="{{ route('fieldequips', ['hex'=>3]) }}" :active="request()->routeIs('fieldequips')">{{ __('Equipment') }}
</x-jet-dropdown-link>

My url looks like this http://localhost:8000/fieldequips/3 But somehow when i try to retrieve the 3 from url using my render function in Fieldequips class

public function render(Request $request)
    {


        $hex=$request()->hex;
        if($hex=3){
        $this->fieldequips = Fieldequip::all();}

        return view('livewire.fieldequips');
    }

它总是失败，我如何将其格式化为正确的方式？

您仍然可以键入提示 Illuminate\Http\Request 并通过定义 controller 方法来访问您的路由参数十六进制，如下所示：

public function render(Request $request, $hex)
    {
        if($hex=3){
        $this->fieldequips = Fieldequip::all();}

        return view('livewire.fieldequips');
    }
