发行按价格订购产品

Question

I want to order products by price with one link for low to high and the other high to low, But after I click "low to high" or "high to low" the order is not changing, it stays on the same page but the url is changing.

this is the function in the controller:

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')); 
    }
}

this is the route:

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

those are the link from the view, the view is 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>

the model:

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();
        }
    }
}

Answer 1

I think there's problem in your condition, but for the problem the page is not change. I think you can make your return outside the if statement. So the code should be like this:

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')); 
}

It will give you little error, but I think your page will change :D

In View -

<a href="{{ url('shop/'.$category['url'].'/sorting')}}?sort=ASC" style="color:black"> High to low</a>

In Route -

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

In Controller -

 public function products(Request $request, $category_url)
{
    $data = Input::all();

    Product::getProducts($category_url, self:: $data);

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

            if( !isset($data['sort']) )
               $data['sort'] = 'ASC';

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

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

I think you should set products in data.

if ( $category1 = Categorie::where('url', '=', $category_url)->first() ) {
    self::$data['products'] = Product::where('categorie_id', $category1->getAttribute('id'))->orderBy('price', $sort)->get();
}
