Question

This is the code where I need to set the value for the label :

{!! Form::label('unit',$value=$fileN) !!}

When I coded that it will display the following error.

ErrorException in UploadController.php line 51: Undefined index: unit

I changed that to {{ Form::label('unit', $fileN) }}. But above same error will display. Below is the output.

<label for="unit">rainforest.pdf</label>

Controller method look likes below.

public function edit1()
{

    $grade = $_POST['grade'];
    $subject = $_POST['subject'];
    $id = $_POST['id'];
    $title = $_POST['title'];
    $unit = $_POST['unit'];
    $uplds = Upldtbl::findOrFail($id);


    DB::table('upldtbls')
        ->where('id', $id)
        ->update(['title' => $title, 'subject' => $subject,'url' => $unit, 'grade' => $grade]);


    return redirect('/hgh');
}


{!! Form::open(array('url'=>'hgh1','method'=>'POST', 'files'=>true, 'class'=>'upldform')) !!}
                                    <table>

                                        {!! Form::close() !!}

Can anybody help me that out?

您的标签声明错误，而不是：

{!! Form::label('unit',$value=$fileN) !!}

应该是：

{{ Form::label('unit', $fileN) }}

您收到错误Undefined index: unit，因为您没有名称为unit的任何字段，而您正试图将其捕获：

 $unit = $_POST['unit'];

您可以使用隐藏字段发送单位值，如：

{!! Form::hidden('unit',$fileN) !!}

希望这有帮助。
