        $request->validate([
            'name'=>'required',
            'description'=>'required',
            'images'=> 'nullable',
            'price'=>'required|numeric',
            'quantity'=>'required|numeric',
        ]);    
    $product = Product::findOrFail($id);
    $product->name=$request->name;
    $product->description=$request->description;
    $product->price=$request->price;
    $product->quantity=$request->quantity;   
    $product->update();
}

There is products table, images table and product_images table. It works fine while adding new product. But when I update the record, instead of updating data it creates new record.

CodePudding user response：

$product = Product::where('id', $id)->first();

if(is_null($product)) {
    $product = new Product();
}

$product->name = $request->input('name');
$product->description = $request->input('description');
$product->price = $request->input('price');
$product->quantity = $request->input('quantity');

$product->save();
