Get related products for a product by category - laravel

Question

I'm trying to show products related to a category. But it is showing all products which are also related to other categories.
Blade:
<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>
Controller:
public function products(Request $request, Product $product)
{
$categories = Category::with('products')->distinct()->get();
return view('product.listing', compact('product', 'categories'));
}
Route:
Route::get('/product/{id}','Admin\ProductController#products')->name('product.products');

Answer 1

Edit your controller:
public function products(Request $request, Product $product)
{
$categories = $product->categories;
return view('product.listing', compact('product', 'categories'));
}
Also you should have the categories relationship method on Product Model.

Answer 2

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 3

Your route is
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.
Controller
//$id is from route.
public function products($id)
{
$products = Product::with('category')->where('category_id',$id)->get();
return view('product.listing', compact('products'));
}
In your blade file
#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 4

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 5

Assuming a product has one category and you have a category_id column in your products table change products method in your ProductController like below.
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'));
}
Replace id in your route withproduct`. Read More about route model binding.
Route::get('/product/{product}','Admin\ProductController#products')->name('product.products');
Then in your view your you can iterate through relatedProducts

controller:
public function products(Request $request, Category $category)
{
$category->load('products');
return view('product.listing', compact('category'));
}
route:
Route::get('/product/{category}','Admin\ProductController#products')->name('product.products');
blade file:
#foreach ($category->products as $product)
<div class="col-sm-12 col-md-6 col-lg-4 p-b-50">

<div class="block2">
<div class="block2-img wrap-pic-w of-hidden pos-relative block2-labelnew">
