这是我的控制器
public function show($id)
{
$products = Item::find($id)->products;
$categories = Item::all();
return view('category.index', compact(['categories', 'products']));
}
这是我的观点

我想在同一视图中传递我的类别列表和产品项目。但我无法将这两个变量从控制器传递给我的视图。它显示了这个错误。
未定义变量:产品(查看:/var/www/html/hzone_new/resources/views/category/index.blade.php)
答案 0 :(得分:1)
更新您的控制器功能,如:
$categories = Item::all();
$products = Item::find($id)->products;
return view('category.index', compact('categories', 'products'));
注意:您无法在函数中定义产品变量,请定义
@if(!empty($products))
@foreach($products as $key=>$product)
<div class="col-md-4 col-sm-6 portfolio-item" id="items">
<div class="card h-100">
<a href="#"><img class="card-img-top" src="/storage/{{ $product->image }}" alt="Product Image"></a>
<div class="card-body">
<h4 class="card-title">
<a href="#"><br />{{ $product->item_name}}</a>
</h4>
<p class="card-text" style="color: #A9A9A9;text-decoration: line-through;">LKR {{ $product->old_price}}</p>
<h4 style="text-align: center; color: #fff;"><a class="waves-effect waves-light btn btn-dark btn-block">LKR {{ $product->new_price}}</a></h4>
</div>
</div>
</div>
@endforeach
@endif
