ErrorException 数组到 Controller 文件中的字符串转换

Question

大家好，我的 controller 出现此 laravel 错误，我需要帮助

这是我的 controller

        public function expectingpost(Request $request)
            {

                DB::table('expectings') ->insert([

                    $validatedData = $request->validate([
                        "time" => 'required|date_format:H:i',
                        "day" => 'required|date_format:Y-m-d',
                        "name" => 'required'
                    ]).

                    "time" => $request->time,
                    "day" => $request->date,
                   "name" => $request->name
                ]);

                return back() -> with('expecting', $request->input('name') . ' has been added as your guest');
            }
        }

请大家，我真的需要快速响应，因为这让我在甲板上待了很长时间。 谢谢

您不应该在插入中验证您的数据，这应该首先验证您的数据，然后使用它来创建您的 model。 另一个改进是使用 Eloquent 型号，如果您刚刚起步，没有理由不这样做。

public function expectingpost(Request $request)
{
    $validatedData = $request->validate([
        'time' => 'required|date_format:H:i',
        'day' => 'required|date_format:Y-m-d',
        'name' => 'required'
    ]).

    Expecting::create($validatedData);

    return back()->with('expecting', $validatedData['name'] . ' has been added as your guest');
}

您需要的 Eloquent Model。

use Illuminate\Database\Eloquent\Model;

class Expecting extends Model {
    protected $fillable = ['time', 'day', 'name'];
}
