Displaying current class in laravel

I'm trying to get my menu to display the current class, I can do it with the id, but at the moment I'm using my seo table to display a url.html instead of an id.

My route

Route::get('/{id}', function($id = 1){
    if(is_numeric($id))
    {
        $menu = App\Modules\Menu\Models\Menu::find($id); 
        $action = 'content';
        return App::make('App\Modules\Open\Http\Controllers\OpenController')->$action($id);
    }else{
        $column = 'url';
        $url = App\Modules\Seo\Models\Seo::where($column, '=', $id)->get();
        $seo = App\Modules\Seo\Models\Seo::where('url', $id)->firstOrFail();
        foreach($seo->menu as $test){
            $test_url = $test->id;
        }

        $action = 'content';
        return App::make('App\Modules\Open\Http\Controllers\OpenController')->$action($test_url);
    }
});

My menu_active function in my helpers.php

function menu_active($test_url){



    if(is_array($id)){
        return in_array(Request::path(), $test_url) ? 'current' : '';
    }

    return Request::path() == $test_url ? 'current' : '';
}
