【问题描述】：
我有一个表单 payments 有 4 个字段 -> date_paying, type_sitting, number_seance, fk_student。
在我的表单 trainings 中，我有 3 个字段 -> date_sitting, fk_payment, fk_student。
我的问题是，当我想添加录音时，我在下拉列表中检索到相同值的 2 倍。
我真的只想保留一件物品
在我的 create.blade(trainings) 我有这个：
<div class="form-group {{ $errors->has('fk_payment') ? 'has-error' : '' }}">
<label for="company-content">Payment </label>
<select name="fk_payment" id="fk_payment" class="form-control" required="required" value="{{ old('fk_payment')}}"/>
<option value="">Choice Payment</option>
@foreach($payments as $payment)
<option value="{{$payment->id}}" {{ old('fk_payment') == $payment->id ? 'selected' : '' }} >
{{$payment->type_sitting}}
</option>
@endforeach
{!! $errors->first('fk_payment', '<span class="help-block">:message</span>') !!}
</select>
这是我的控制器培训
class TrainingController extends Controller
{
/**
* Display a listing of the resource.
*
* @return \Illuminate\Http\Response
*/
public function index()
{
$trainings = Training::oldest()->paginate(5);
return view('admin.trainings.index', compact('trainings'));
with('i', (request()->input('page', 1) -1) *5);
}
/**
* Show the form for creating a new resource.
*
* @return \Illuminate\Http\Response
*/
public function create()
{
$payments = Payment::all();
$students = Student::all();
return view('admin.trainings.create', compact('payments', 'students','trainings'));
}
/**
* Store a newly created resource in storage.
*
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
*/
public function store(Request $request)
{
$request->validate([
'date_sitting' => 'required',
'fk_payment' => 'required',
'fk_student' => 'required'
]);
$exists = Training::where('date_sitting', $request->get('date_sitting'))->where('fk_payment', $request->get('fk_payment'))->where('fk_student', $request->get('fk_student'))->count();
if (!$exists){
//$payment = Payment::where('fk_student', $request->get('fk_student'))->first();
$payment = Payment::where('fk_student', $request->get('fk_student'))
->take(1)
->get();
if(!isset($payment)){
return redirect()->route('trainings.index')
->with('error', 'No Payment, no training for you!');
}
else{
Training::create($request->all());
return redirect()->route('trainings.index')
->with('success', 'new data created successfully');
}
}
}

【问题讨论】：
-
你能在控制器中
dd($payements)并发布结果吗？
