"{{$ item-> id}}"

MyController.php - contains the method:

public function results(Request $request){

}

Answer 1

Just make a form and post it , or have some hyperlink

<form  method="POST" action="/route_to_your_controller">
            {{ csrf_field() }} 
            <input type="hidden" name="item_id" value="{{$item->id}}" required>
</form>

Route

Route::post('/route_to_your_controller', 'yourController@results');

Controller

public function results(Request $request){
{
    $name = $request->input('item_id')     
}

Answer 2

在你的MyController中使用

public function results(Request $request, Item $item){
    //and here I want to use the value {{$ item-> id}}
 $item_id = $item->id;
}
