發行按照價格在laravel訂購產品

Question

我想訂購產品的價格與一個鏈接從低到高和其他高到低， 但我點擊「由低到高」或「從高到低」的順序沒有改變，它保持在同一頁面上，但url正在改變。

這是在控制器中的功能：

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')); 
    } 
} 

這是路由：

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

那些是從視圖的鏈接，該視圖是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> 

該型號：

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(); 
     } 
    } 
}

在你的控制器試試這個：

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')); 
}
