Laravel7-表單

我有一個表格來編輯和更新學生的某些值，比如成績、獎學金、評論等。我有一個@foreach這樣我可以一個一個地更新每個學生，但我想改變它，我想最后發送所有學生的所有資料，而不是一一發送。根據我所擁有的，我可以這樣做嗎？

• 學生控制器

    public function enroll($id_student, request $request)
        {
            try {
                $idGroup = $request->get('idGroup');
                $student = Students::where('id_student', $id_student)->first();
                $student->groups()->attach([$idGroup => ['InvoiceNumber' => $request->get('InvoiceNumber'), 'Comments' => $request->get('Comments'), 'scolarship' => $request->get('scolarship') ? $request->get('scolarship') : 0]]);
                return back()->with('success', 'Student successfully enrolled');
            } catch (\Illuminate\Database\QueryException $e) {
                $message = $e->getMessage();
                if (strpos($message, "Duplicate entry")) {
                    return back()->with('err', 'This Student is already registered in this group');
                }
                if (strpos($message, "1366 Incorrect integer value: '' for column 'idGrupo'")) {
                    return back()->with('err', 'You must select a group to continue');
                }
                return back()->with('err', $message);
            }
        }
    
        public function enrollEdit($id_student, $idGroup, Request $request)
        {
            try {
                $student = Students::where('id_student', $id_student)->first();
                $group = $student->groups()->where('groups.idGroup', $idGroup)->first();
                $group->pivot->NumeroDeFactura = $request->get('NumeroDeFactura');
                $group->pivot->Comentarios = $request->get('Comentarios');
                $group->pivot->beca = $request->get('beca') ? $request->get('beca') : 0;
                $group->pivot->calificacion = $request->get('calificacion');
                $group->pivot->save();
                return back()->with('success', 'Enrollment edited successfully');
            } catch (\Throwable $th) {
                return back()->with('err', 'Error: ' . $th->getMessage());
                //throw $th;
            } catch (\Illuminate\Database\QueryException $e) {
                $mensaje = "There is already a student with that registered email";
                return back()->with('err', $mensaje);
            }
        }

• 看法

   
  @foreach ($group->students as $student)
     <tr>
        <td class="align-middle ">
            @if ($student->pivot->scolarship == 0 && $student->pivot->InvoiceNumber == '')<!--Validacion para imprimir icono de no pago-->
                <i class="material-icons text-danger">payment</i>
            @endif
            <i class="material-icons">{{$student->pivot->scolarship?'school':''}}</i>
            {{$student->Last_Name}} {{$student->Apellido_Materno}} {{$student->Names}}
        </td>
        <td class="align-middle text-center">
            <form method="post" action="{{url('Students/enroll/'.$student->id_student.'/'.$group->idGroup.'/edit')}}">  
                 {{csrf_field()}}
                 <input  {{$student->pivot->scolarship=='1'?'checked':''}} type="checkbox" name="scolarship" value="1"></td>
                 <td hljs-string">"><input name="InvoiceNumber" type="text" value="{{isset($student->pivot->InvoiceNumber)?$student->pivot->InvoiceNumber:''}}" hljs-string">" placeholder="Factura"></td>
                 <td hljs-string">"><input name="grade" type="text" value="{{isset($student->pivot->grade)?$student->pivot->grade:''}}" hljs-string">" placeholder="grade"></td>
                 <td hljs-string">"><textarea name="Comments" type="text"  hljs-string">" placeholder="Comments"  rows="1">{{isset($student->pivot->Comments)?$student->pivot->Comments:''}}</textarea></td>
                  <td hljs-string">">
                      <button type="submit"  hljs-string">"> @lang('show.Save')<i hljs-string">" style="font-size:20px">save</i></button>
                  </td>

                  <td hljs-string">">
                       <form method="post" action="{{url('Groups/Disenroll/'.$group->idGroup.'?idStudent='.$student->id_student)}}">
                             {{csrf_field()}}
                             <button type="submit"  hljs-string">"  > <i hljs-string">" style="font-size:10px">call_split</i></button>
             </form>
                 </td>
     </tr>
  @endforeach

一切正常，但視圖總是在保存其中一個學生的資料后重新加載，因此快速逐個學生保存以不洗掉其他學生的修改資訊有點繁瑣。

怎么可能修改？使表單發送所有資料而不一一保存。

您可以使用jquery ajax創建發布請求。那么你可以在不重繪 頁面的情況下更新資料庫

你必須使用：

<input  {{$student->pivot->scolarship=='1'?'checked':''}} type="checkbox" name="scolarship[]" value="1"></td>
