如何在laravel中验证多个记录插入？

Question

我的应用程序有一个表单,我插入多个记录,每个记录是一个新的表单.我想验证每个表单中的每个字段我试图使用验证功能,但我很困惑如何为多个记录插入它？对于这个项目,我正在使用laravel 5.2.

多个插入的存储功能

public function store(Request $request)
    {
        $this->validate($request,[
            'name' => 'required|min:4',
            'fname' => 'required',
            'rollno' => 'required|unique:students'
        ]);
        $input = $request->all();
        $condition = $input['name'];
        foreach ($condition as $key => $condition) {
            $student = new Student;
            $student->name = $input['name'][$key];
            $student->fname = $input['fname'][$key];
            $student->rollno = $input['rollno'][$key];
            $student->obtainedmarks = $input['obtainedmarks'][$key];
            $student->totalmarks = $input['totalmarks'][$key];
            $student->percentage = $input['percentage'][$key];
            $student->save();
        }
        return Redirect::to('/allresults');

}

查看用于插入数据

<script type="text/javascript">

            var n = ($('.resultbody tr').length - 0) + 1;
            var tr = '<tr><td class="no">' + n + '</td>' +
                    '<td><input type="text" class="name form-control" name="name[]" value="{{ old('name') }}"></td>'+

        $('.resultbody').delegate('.delete', 'click', function () {

更新:在视图中你会注意到有一个按钮,当用户点击"添加新"它添加新行我想要验证所有行,每行包含一个记录.

我认为你可以这样做来验证你的数组输入.

'input_name.*' => 'rules'

https://laravel.com/docs/5.2/validation#validating-arrays

所以在你的情况下这个:

$this->validate($request,[
     'name.*'   => 'required|min:4',
     'fname.*'  => 'required',
     'rollno.*' => 'required|unique:students'
 ]);
