Question

我想按价格订购产品，一个链接从低到高，另一个从高到低，但是，在我点击“从低到高”或“从高到低”后，订单不会改变，它会停留在同一页面上，但网址会发生变化。

这是控制器中的功能：

public function products(Request $request, $category_url, $sort= 'ASC')
{
    Product::getProducts($category_url, self:: $data);

    if ( $category1 = Categorie::where('url', '=', $category_url)->first() ) {

        $products = Product::where('categorie_id', $category1->getAttribute('id'))->orderBy('price', $sort)->get();

        return view('content.products', self::$data , compact('products', 'sort')); 
    }
}

这是路线：

  Route::get('shop/{category_url}/sorting-{sort?}', 'ShopController@products');

这些是视图中的链接，视图是content.products

  <a href="  {{ url('shop/'.$category['url'].'/sorting-asc')}}" style="color:black"> High to low</a> |
  <a href="  {{ url('shop/'.$category['url'].'/sorting-desc')}}" style="color:black">Low to high</a>

模特：

class Product extends Model {


static public function getProducts($category_url, &$data){

    $data['products']=$data['category']=[];


    if ($category=Categorie::where('url','=', $category_url)->first()){

        $category= $category->toArray();
        $data['category']=$category;
        $data['title']=$data['title']. ' | ' . $category['title'];


        if ($products=Categorie::find( $category['id'])->products){

            $data['products']= $products->toArray();
        }
    }
}

在你的控制器中试试这个：

if ( $category1 = Categorie::where('url', '=', $category_url)->first() ) {

    $products = Product::where('categorie_id', $category1->getAttribute('id'));
    $products = strtolower($sort) == 'asc' ? $products->orderBy('price'):$products->orderByDesc('price');
    $products = $products->get();

    return view('content.products', self::$data , compact('products', 'sort')); 
}
