Laravel把产品通过传递ID

Question

我有产品ID的数组，我在我的控制器

public function productsCart(Request $request) 
{ 
    //dd($request->products); 

    foreach ($request->products as $key => $product) { 

     $product = Product::where('id', $product[0])->get(); 

    } 

    return Response::json($product); 
} 

我得到空读取所有属于该ID

{ 
    "products":[1,2,3,4,5,6] 
} 

产品数组作为响应

谢谢

Answer 1

试试这个

public function productsCart(Request $request) 
{ 
    $products = Product::whereIn('id', $request->products)->get(); 

    return Response::json($products); 
} 

Answer 2

使用whereIn

public function productsCart(Request $request) 
{ 
    $products = Product::whereIn('id', $request->products)->get(); 

    return Response::json($products); 
} 

，或者如果你想循环再

foreach ($request->products as $id) { 

     $product[] = Product::where('id', $id)->get(); 

    }
