Laravel 5.2数组到字符串转换误差表格

Question

我的工作项目简单表单，但我得到了错误：

350957EC60E1DD25A26F206394651974BB23E6B7.PHP线 40：到字符串转换的数组（查看： c： xampp htdocs laravelku resources views siswa siswa edit.blade.php）

这是我的代码：

@extends('template')
@section('main')
    <div id="siswa">
        <h2>Edit Siswa</h2>
        {!! Form::model($siswa,['method' => 'PATCH', 'action' => ['SiswaController@update', $siswa->id]]) !!}
        <div class="form-group">
            {!! Form::label('nisn', 'NISN:', ['class' => 'control-label']) !!}
            {!! Form::text('nisn', null,['class' => 'form-control']) !!}
        </div>
            <div class="form-group">
                {!! Form::label('nama_siswa','Nama:',['class' => 'control-label']) !!}
                {!! Form::text('nama_siswa',null,['class' => 'form-control']) !!}
            </div>
        <div class="form-group">
            {!! Form::label('tanggal_lahir','Tanggal Lahir:',['class' => 'control-label']) !!}
            {!! Form::date('tanggal_lahir',null,['class' => 'form-control','id' => 'tanggal_lahir']) !!}
        </div>
        <div class="form-group">
            {!! Form::label('jenis_kelamin','Jenis Kelamin:', ['class' => 'control-label']) !!}
            <div class="radio">
                <label>{!! Form::radio('jenis_kelamin', 'L') !!} Laki-laki</label>
            </div>
            <div class="radio">
                <label>{!! Form::radio('jenis_kelamin','P') !!} Perempuan</label>
            </div>
        </div>
        <div class="form-group">
            {!! Form::submit('Update Siswa'), ['class' => 'btn btn-primary form-control'] !!}
        </div>
        {!! Form::close() !!}
    </div>
    @stop
    @section('footer')
        @include('footer')
    @stop

Answer 1

Form::submit()语法是错误的。更改此：

{!! Form::submit('Update Siswa'), ['class' => 'btn btn-primary form-control'] !!}

：

{!! Form::submit('Update Siswa', ['class' => 'btn btn-primary form-control']) !!}
