I need to add check boxes for services like " facebook, twitter, youtube" in client creation page the values will be the same name and should be saved in service column to be viewed in a table for clients

how to do it in controller and create view

this is the controller @store

 $input = $request->except('service');

    $services =  $request['service'];

    if(isset($services)) {

        foreach ($services as $service) {

            $input['service'] = $services;
        }
    }

    Client::create($input);
    return redirect('admin/clients');
