Question

如何通过laravel路线的价格订购产品？如何将其标记到路线的末尾？这是溃败

路线::得到（＆＃39;店/ {category_url}排序= ASC＆＃39;＆＃39; SortController @ sortByASC＆＃39）;

Answer 1

您无需在路线中添加，只需将其传递给网址，例如

Route::get('shop/{category}', 'SomeController@someFunction');

现在你的控制器功能：

public function someFunction($category, Request $request)
{

     $query = Model::query();
     if($request->sort)
      {
        $query = $query->orderBy('price', $request->sort);
      }
   $query = $query->get();
}

从您的视图构建此网址

<a href="/shop/{{$category}}?sort=ASC">Sort product ascending</a>

我们假设你的链接看起来像。 ... /店/种类？排序= ASC。您可以在控制器中获取get参数的值：

Route::get('shop/{category_url}','SortController@sort');

在您的content / sort.blade.php文件中：

class SortController extends MainController{
    public function sortByASC($category, Request $request)
    {
        if ($category1 = Categorie::where('url', '=', $category)->first()) {
            $sort = $request->get('sort', 'asc');
            $products = Product::where('categorie_id', $category1->getAttribute('id'))->orderBy('price', $sort)->get();
            $sort = $sort == 'asc' ? 'desc' : 'asc'; // to use in sort link
            return view('content.sort', compact('products', 'sort'));
        }
    }
}
