Question

我正在尝试显示与某个类别相关的产品。但是它显示了与其他类别也相关的所有产品。

刀片：

<div class="row">
    @foreach($categories as $category)
        @foreach ($category->products as $product)
        <div class="col-sm-12 col-md-6 col-lg-4 p-b-50">
        <!-- Block2 -->
            <div class="block2">
                <div class="block2-img wrap-pic-w of-hidden pos-relative block2-labelnew">
                    <img src="{{ URL::to('/') }}/images/backend_images/product_images/{{ $product->product_image }}" 
                        class="img-thumbnail" style="width: 270px; height: 360px;" />
                    <div class="block2-overlay trans-0-4">

                    </div>
                </div>

                <div class="block2-txt p-t-20">
                    <a href="product-detail.html" class="block2-name dis-block s-text3 p-b-5">
                        {{ $product->product_name }}
                    </a>

                    <span class="block2-price m-text6 p-r-5">
                        $75.00
                    </span>
                </div>
            </div>
        </div>
        @endforeach
    @endforeach
</div>

控制器：

public function products(Request $request, Product $product)
{
    $categories = Category::with('products')->distinct()->get();
    return view('product.listing', compact('product', 'categories'));
}

路线：

Route::get('/product/{id}','Admin\ProductController@products')->name('product.products');

Answer 1

public function products(Request $request, Category $category)
{
     $products = Product::where('category_id',$category->id)->get();
     $categories = Category:all();
     return view('product.listing', compact('products','categories'));
}

Answer 2

编辑控制器：

  public function products(Request $request, Product $product)
  {
      $categories = $product->categories;
      return view('product.listing', compact('product', 'categories'));
  }

此外，您还应该在产品模型上具有类别关联方法。

Answer 3

    public function products(Request $request)
      {
          $categories = Category::where('id',$request->id)->with('products')->get();
          return view('product.listing', compact('categories'));
      }

 @foreach($categories as $category)
                        @foreach ($category as $product)

Answer 4

您的路线是

Route::get('/product/{id}','Admin\ProductController@products')->name('product.products'); 
//{id} it means you're getting category id from route right? so you can directly access it in controller.

控制器

//$id is from route.
public function products($id) 
{
  $products = Product::with('category')->where('category_id',$id)->get();

  return view('product.listing', compact('products'));
}

在您的刀片文件

中

@foreach($products as $product)
//here your all product which belongs to that categories.
and now if you want to access categories then may do as.

categories :- {{ $product->category->name }} //make sure it belongsTo in product

@endforech

Answer 5

假设产品具有一个类别，并且在category_id的{{1}}表更改products方法中有一个products列，如下所示。

ProductController

在您的public function products(Request $request, Product $product) { $relatedProducts = Product::where('category_id', $product->category_id) ->where('id', '!=', $product->id) // ignore current product ->get(); return view('product.listing', compact('product', 'relatedProducts')); }产品中替换id。 Read More about route model binding.

route with

然后在您看来，您可以通过Route::get('/product/{product}','Admin\ProductController@products')->name('product.products');进行迭代

Answer 6

控制器：

  public function products(Request $request, Category $category)
  {
    $category->load('products');
    return view('product.listing', compact('category'));
  }

路线：

  Route::get('/product/{category}','Admin\ProductController@products')->name('product.products');

刀片文件：

   @foreach ($category->products as $product)
                    <div class="col-sm-12 col-md-6 col-lg-4 p-b-50">
                        <!-- Block2 -->
                        <div class="block2">
                            <div class="block2-img wrap-pic-w of-hidden pos-relative block2-labelnew">
                                <img src="{{ URL::to('/') }}/images/backend_images/product_images/{{ $product->product_image }}" class="img-thumbnail" style="width: 270px; height: 360px;" />


                            </div>


                        </div>
                    </div>
                @endforeach

按类别获取产品的相关产品
