嘗試以下代碼


public function store(Request $request)

{

    //Validation the Data


    $validatedData = $request->validate([

        'designation_type' => ['required','max:255'],

        'status' => ['required'],

    ],

    [

        'designation_type.required' => 'Designation is required',

        'designation_type.max' => 'Designation should not be greater than 255 characters.',

    ]);



    if($validatedData->fails()) {

      return Redirect::back()->withErrors($validatedData);

    }



    //Data Insert into database

   $data =[

       'designation_type'=>$request->input('designation'),

       'status'=>$request->input('status')

   ];

   DB::table('designation')->insert($data);


   return redirect('/designation');

}





<form action="{{url('./designation/store')}}" method="POST">

      <div class="form-row">

        <div class="form-group col-md-7">

          <label for="inputDesignation">Designation</label>

          <input type="text" name="designation" class="form-control" id="inputDesignation">

          @if($errors->has('designation'))

            <div class="error">{{ $errors->first('designation') }}</div>

        @endif

        </div>

        <div class="form-group col-md-5">

          <label for="inputStatus_Designation">Status</label>

          <select name="status" id="inputStatus_Designation" class="form-control">

            <option selected>Select Status</option>

            <option >Active</option>

            <option >Inactive</option>

          </select>

          @if($errors->has('status'))

            <div class="error">{{ $errors->first('status') }}</div>

        @endif

        </div>

      </div>


      <button type="submit" class="btn btn-success" id="btn_add_designation">Add</button>

參考此https://laravel.com/docs/5.6/validation#named-error-bags后，我對代碼進行了一些更改，這有助于解決錯誤。


在designation.blade.php添加


 @if ($errors->any())

<div class="alert alert-danger">

    <ul>

        @foreach ($errors->all() as $error)

            <h6>{{ $error }}</h6>

        @endforeach

    </ul>

</div>

@endif

在DesignationController.php


用于狀態(tài)下拉驗證。


'status' => 'required|not_in:0',

用于數(shù)據(jù)插入數(shù)據(jù)庫部分


DB::table('designation')->insert($validatedData);

完整代碼


designation.blade.php


<div class="row">

  <div class="col-md-2"></div>

    <div class="col-md-8">

      @if ($errors->any())

        <div class="alert alert-danger">

        <ul>

        @foreach ($errors->all() as $error)

            <h6>{{ $error }}</h6>

        @endforeach

    </ul>

</div>

@endif

</div>

 <div class="col-md-2"></div>

 </div>

 <div class="row">

<div class="col-md-4"></div>

<div class="col-md-4">

  <form action="{{url('./designation/store')}}" method="POST">

      <div class="form-row">

        <div class="form-group col-md-7">

          <label for="inputDesignation">Designation</label>

          <input type="text" name="designation_type" class="form-control" id="inputDesignation">

        </div>

        <div class="form-group col-md-5">

          <label for="inputStatus_Designation">Status</label>

          <select name="status" id="inputStatus_Designation" class="form-control">

            <option selected value="">Select Status</option>

            <option value="Active">Active</option>

            <option value="Inactive">Inactive</option>

          </select>

        </div>

      </div>

      {{-- <button type="submit" class="btn btn-primary">Sign in</button> --}}

      <button type="submit" class="btn btn-success" id="btn_add_designation">Add</button>

      {{ csrf_field() }}



  </form>

</div>

 <div class="col-md-4"></div>

</div>

指定控制器.php


public function store(Request $request)

{

    $validatedData = $request->validate([

        'designation_type' => 'required|max:255',

        'status' => 'required|not_in:0',

    ],

    [

        'designation_type.required' => 'Designation is required !!',

        'designation_type.max' => 'Designation should not be greater than 255 characters.',

        'status.required' => 'Status is required !!'

    ]);


    DB::table('designation')->insert($validatedData);

    return redirect('/designation');

}

謝謝你們花費寶貴的時間來幫助我....!!!
