Question

我有一个包含输入字段的表，我必须从中获取信息并保存它，但我还必须从表中的每一行获取信息。我有一个整个表的提交按钮。

我需要获取$student的ID和$subject的ID。我怎么能得到它们？

我发布了表格

 <table class="table table-responsive table-striped" id="admin-table">
    <thead>
    <tr>
        <th>Клас:</th>
        <th>N:</th>
        <th>Име:</th>
        <th>Предмет:</th>
        <th>Оценка:</th>
        <th>Тип на оценката:</th>

    </tr>
    </thead>
    <tbody>
    @foreach($students as $student)
        @foreach($class as $classes)
          @foreach($sub as $subject)
        <tr>
            <td>
                {{$classes->name}}
            </td>
            <td>
                {{$student->number_in_class}}

            </td>
            <td>
                {{$student->full_name}}
            </td>
            <td>
                {{$subject}}
            </td>
            {!! Form::open(['action' => 'Educator\AccountController@markStudent', 'class' => 'form-horizontal']) !!}
            <td>
                {!! Form::text('mark',null, ['class'=>'form-control col-md-2']) !!}
            </td>
            <td>
                {!! Form::select('markType', $markType, null, ['class'=>'form-control']) !!}
            </td>
        </tr>
            @endforeach
          @endforeach
        @endforeach
    </tbody>
</table>
    <div align="center">
        <a href="{{url('educator/class-subject')}}"><button type="button" class="btn btn-default">Назад</button></a>
        {!! Form::submit('Запиши', ['class' => 'btn btn-default']) !!}

    </div>
    {!! Form::close() !!}

控制器中的方法：

public function postIndex(Request $request)
{

    $user = Auth::user();

    ClassSubject::where([
        ['subject_id', $request->input('subject')],
        ['class_id', $request->input('class')]
    ])->get();

    return view('educator.account.input', [
        'user' => $user,
        'class'=> Clas::where('id', '=', $request->get('class'))
            ->get(),
        'students' => User::where('class_id', '=', $request->get('class'))
            ->orderBy('first_name', 'asc')
            ->get(),
        'markType' => MarkType::get()
            ->pluck('type', 'id'),
        'sub' => Subject::where('id', '=', $request->input('subject'))
            ->get()
            ->pluck('name','id')
    ]);

}

我保存所需数据的方法：

public function markStudent(Request $request)
{
    $validator = Validator::make($request->all(), [
        'mark' => 'numeric|required|min:2|max:6',
    ]);

    if ($validator->fails()) {
        return redirect()
            ->back()
            ->withErrors($validator)
            ->withInput();
    }

    StudentMark::create([
        'student_id' => the student id which i have to get from the table in the view,
        'subject_id' => $request->the subject id which i have to get from the table in the view,
        'mark_type_id' => $request->input('markType'),
        'mark' => $request->input('mark')]);

    $user = Auth::user();
    $subject = ClassSubject::where('teacher_id', $user->id)
        ->get()
        ->pluck('subject_id', 'id');


    return view('educator.account.marks', [
        'user' => Auth::user(),
        'marks' => StudentMark::whereIn('subject_id',$subject)
            ->orderBy('created_at', 'desc')
            ->get(),
    ]);

}

Answer 1

向上移动Form::open，在@foreach子句之后但在数据之前放置一些：

然后将布局更改为：

<td>
    {!! Form::label('classes_name', $classes->name) !!}
</td>
<td>
    {!! Form::label('student_number_in_class', $student->number_in_class) !!}
</td>
<td>
    {!! Form::label('student_full_name', $student->full_name) !!}
</td>
<td>
    {!! Form::label('subject', $subject) !!}
</td>

然后像往常一样访问此信息：

$request->input('student_number_in_class'),

我没有测试过，但这应该可行。如果label不适合您，请尝试使用其他表单类型。

Answer 2

只需在保存结果的控制器方法上添加此查询即可。

$studentid = Student::where('colname','=',colvalue)->select('id')->first();
$subjectid = Subject::where('colname','=',colvalue)->select('id')->first();

您在视图中传递给控制器的任何数据。使用该信息获取学生和主题的ID。我无法得到确切的解决方案，因为我不知道数据库中每个表的表或列名之间的关系。
