laravel：单击第二个分页的下一页时如何删除第一个分页

Question

我有两个分页传递到的索引页面。首先，我让幻灯片显示特色项目，然后在该滑块通过第二个分页之后还有其他项目。但是当我点击下一页时。第一个分页项不显示，但该 div 的标题仍然存在。我的问题是我可以做些什么来删除除索引页面和 ?page=1 at url 之后的页面之外的任何其他页面上特色项目滑块的整个 div。我试图设置 if 条件，但是当 url 没有获取值时，它会给我错误。是否有任何解决方案可以在除 1 和简单索引之外的任何其他页面上隐藏整个滑块 div。

    class IndexController extends Controller
    {
        public function Index(){
            //Get all Products 
            $allProducts = DB::table('categories')
                ->join('products','products.category_id','=', 'categories.id')
                ->where('categories.status','=','1')->where('products.status','=','1')->paginate(9);


            // Get featured products
            $featuredProducts = DB::table('categories')
                ->join('products','products.category_id','=', 'categories.id')
                ->where('categories.status','=','1')->where('products.status','=','1')->where('feature_item',1)->paginate(25);


            //Get all Categories and sub Categories
            $categories = Category::with('categories')->where(['parent_id'=>0])->get();

            $banners = Banner::where('status','1')->get();

            return view('index')->with(compact('featuredProducts','allProducts','categories','banners'));

        }
    }

Answer 1

您可以使用request()->getQueryString() 来检查查询参数。

@if (!str_contains(request()->getQueryString(), 'page')) || (str_contains(request()->getQueryString(), 'page=1'))
  // show pagination only if page is 1 or there is no page param
@endif
