我无法将数据发送到我的数据库，没有错误

Question

 namespace App\Http\Controllers;
 use  App\Models\Product;
 use Illuminate\Http\Request;
 use Illuminate\Support\Facades\Validator;

 class ProductController extends Controller
 {

 public function store(Request $request) {

    $this->validate($request,[
        'productName' =>'required|max:255',
        'quantity' =>'required',
        'weight' =>'required',
        'boxes' =>'required',
        'MRP' =>'required',
        'costprice' =>'required',
        'image' =>'required|image|mimes:png,jpeg,jpg,gif,svg|max:2048',
        'productDescription' =>'required',
    ]);

    $imageName = time().'.'.$request->image->extension();

    Product::create([
        'productName' => $request->productName,
        'quantity' => $request->quantity,
        'weight' => $request->weight,
        'boxes' => $request->boxes,
        'MRP' => $request->MRP,
        'costprice' =>$request->costprice,
        'productDescription' =>$request->productDescription,
        'image' =>$request->image->move(public_path('images'),$imageName),
        'seller_id' => $request->user('seller')->id,
        'category_id' => $request->category
    ]);
    

    return back()->with('success','Product stocked Successfully...');  
  }
 
  }

无法使用此代码解决问题 这是我的刀片文件，每当我提交表单时，它没有在数据库中插入数据，这是一个问题，我检查了包括模型、迁移等在内的所有内容，但没有收到任何错误但仍然没有提交数据

我希望我的代码在我的数据库中插入数据，但它正在返回并且没有提供错误 或成功，如果我检查我的数据库没有数据请解决问题

Answer 1

你可以这样使用它：

$request->validate($rules);

或

$request->validate([
    'productName' => 'required|max:255'
]);

然后它返回错误。

$test = $productName->validate([
           'productName' => 'required|max:255'
        ]);

你需要检查是否没有错误，然后你可以做任何你想做的事情。

在您的情况下，您需要这样做：

$validator = Validator::make($request->all(), [
    'productName' => 'required|max:255'
]);

if ($validator->fails()) {
    return back()->with('failed','There is error'); 
} else {
    return back()->with('success','Product stocked Successfully...'); 
}
