Laravel 电子商务动态产品过滤

Question

我遇到了一个大问题，找不到解决方法。我正在使用 Laravel 构建一个电子商务应用程序，为产品构建一个良好的过滤系统至关重要。我有 products 和 attributes table 具有多对多关系。枢轴 table product_attribute 有额外的 value（如果 attribute 是颜色，value 将是红色例如）柱子。当进入商店页面时，有一个带有过滤选项的侧边栏。我可以显示的唯一选项是 brand，因为它与产品 table 是一对多关系。显示这些属性的正确方法是什么。正如我提到的，属性对于页面上的产品应该是动态的。不同类别的不同产品（自行车、衣服、球、游泳池 tables）可能具有不同的属性。

public function show($slug){

  // Get products with attributes for specic 
  $category = Category::with('products')->where('slug',$slug)->firstOrFail();

  // Collect brand ids
  $b_ids = array_filter($category->products->pluck('brand_id')->toArray());

  //Get brands to show in the filtering options
  $brands = Brand::whereIn('id',$b_ids)->get();

  $attributes = ?

  return view('front.shop', compact('category','brands', 'attributes'));
  }

Answer 1

预加载产品属性 - Category::with('products.attributes')

public function show($slug){

  // Get products with attributes for specic 
  $category = Category::with('products.attributes')->where('slug',$slug)->firstOrFail();

  // Collect brand ids
  $b_ids = array_filter($category->products->pluck('brand_id')->toArray());

  //Get brands to show in the filtering options
  $brands = Brand::whereIn('id',$b_ids)->get();

 

  return view('front.shop', compact('category','brands'));
}

然后在视图中可以通过产品访问属性

that's not what I want. It just gives me the value. I want attribute name to be displayed at the top (for example COLOR) and values (Red, Blue, etc) at the bottom next to a checkbox for the user to filter

假设您将属性的所有可能值存储为选项

// ...

@foreach($categories as $category)
   @foreach($category->products as $product)
        @include('attribute-options', ['attributes' => $product->attributes])
    @endforeach
@endforeach

// ...

将产品的属性显示提取到部分 - attribute-options.blade.php

@foreach($attributes as $attribute)
    <h3>{{ $attribute->name }}
    <ul>
        @foreach($attribute->options as $option)
            <li>
                <label for="{{$attribute->name}}-{{$option}}">{{ $option }}
                    <input 
                      type="radio" 
                      value="{{$option}}"
                      id="{{$attribute->name}}-{{$option}}"
                      name="{{$attribute->name}}-{{$option}}"
                    />
                </label>
            </li>
        @endforeach
    </ul>
@endforeach
