Question

试图将数据保存到db中，但是它仅返回下一页而不将数据保存到db中，是否有解决此问题的解决方案，

刀片文件：

  public function create(Request $request)
  {

    if ($request->isMethod('post')) {
    $data = $request->all();
    $categories = new Categories;
    $categories->name = $data['category_name'];
    $categories_description = $data['description'];
    $categories->save();

       return view('admin.categories.index');
    }

    return view('admin.categories.create');
  }

Answer 1

您在这里弄错了

$categories_description = $data['description'];

应该是

$categories->description = $data['description'];

希望这会有所帮助：）

Answer 2

存在问题

 $categories = new Categories;

我认为应该是

$categories = new Category;

或

$category = new Category; //preferred

模型是单数形式，按照laravel命名约定，表是复数形式。

此外，如果要批量分配值，请在可填充数组中添加列名。喜欢

protected $fillable = ['name', 'description'];

此外，请确保您的模型位于App文件夹中，并且尚未创建任何子目录，例如“ App \ Models”或其他内容。
