我在Laravel-5.8中有这段代码。有两种型号：
class HrLeaveType extends Model
{
protected $table = 'hr_leave_types';
protected $primaryKey = 'id';
protected $fillable = [
'leave_type_name',
'leave_type_code',
'description',
];
public function leavetypedetail()
{
return $this->hasMany('AppModelsHrHrLeaveTypeDetail');
}
}
class HrLeaveTypeDetail extends Model
{
protected $table = 'hr_leave_type_details';
protected $primaryKey = 'id';
protected $fillable = [
'id',
'leave_type_id',
'company_id',
'employee_type_id',
'no_of_days',
];
protected $casts = [
'data' => 'array',
];
public function leavetype()
{
return $this->belongsTo('AppModelsHrHrLeaveType', 'leave_type_id', 'id');
}
public function employeetype()
{
return $this->belongsTo('AppModelsHrHrEmployeeType', 'employee_type_id', 'id' );
}
}
请求规则
public function rules()
{
return [
'leave_type_name' => [
'required',
'string',
'min:3',
'max:80',
Rule::unique('hr_leave_types')->where(function ($query) {
return $query->where('leave_type_name', $this->leave_type_name)
->where('company_id', $this->company_id);
})
],
'leave_type_code' => [
'nullable',
'string',
'max:10',
Rule::unique('hr_leave_types')->where(function ($query) {
return $query->where('leave_type_code', $this->leave_type_code)
->where('company_id', $this->company_id);
})
],
'no_of_days' => 'required|array',
'no_of_days.*' => [
'required',
'numeric',
'max:120'
],
'employee_type_id' => 'required|array',
'employee_type_id.*' => [
'required',
],
];
}
}
控制器
public function create()
{
$userCompany = Auth::user()->company_id;
$employeetypes = HrEmployeeType::where('company_id', $userCompany)->get();
$leavetype = new HrLeaveType();
return view('leave.leave_types.create')
->with('leavetype', $leavetype)
->with('employeetypes', $employeetypes);
}
public function store(StoreLeaveTypeRequest $request)
{
$userCompany = Auth::user()->company_id;
$leavetype = new HrLeaveType();
$leavetype->leave_type_name = $request->leave_type_name;
$leavetype->leave_type_code = $request->leave_type_code;
$leavetype->description = $request->description;
$leavetype->save();
foreach ($request->employee_type_id as $key => $employee_type_id){
$insert_array = [
'no_of_days' => $request->no_of_days[$key],
'employee_type_id' => $request->employee_type_id[$key],
'leave_type_id' => $leavetype->id,
];
HrLeaveTypeDetail::create($insert_array );
}
Session::flash('success', 'Leave Type is created successfully');
return redirect()->route('leave.leave_types.index');
}
}
LeaveTypeDetail是动态创建的

一种休假类型有许多休假类型的详细信息。对于控制器和视图，我有动态表单输入。leave_type_details是数组。
当用户提交时，如果操作失败，则所有字段都应零售其值。这种情况只发生在leave_type中，但leave_type_details字段没有保留其值。它清除了。
我该如何做到这一点？
感谢
在刀片中：
@if(old('input_name'))
@foreach(old('input_name') as $key => $value)
<your_html>{{old("input_name.{$key}"}}</your_html>
@endforeach
@endif
