我在拉拉维尔中的html表单 5.如何以拉拉维尔形式显示和编辑数据。
{!! Form::open(array('url' => 'addstaff','class'=>'form-signin')) !!}
<div class="row" style="margin-top:-20px;">
<div class="col-md-12">
<h1 class="page-head-line"> Staff
<div class="col-sm-12" style="font-size:12px">
<div class="row" style="margin-top:20px;">
<div class="form-group col-sm-2 col-xs-6">
<label>Title </label>
{!! Form::select('title', array('1' => 'Select', 'Mr.' => 'Mr.', 'Mrs.' => 'Mrs.','Miss' => 'Miss'), null, ['class' => 'form-control']); !!}
</div>
<div class="form-group col-sm-5 col-xs-6">
<label>First Name </label>
{!! Form::text('fname','',array('class' => 'form-control' ,'id' => 'fname' , "placeholder" => 'First Name')) !!}
</div>
<div class="form-group col-sm-5 col-xs-6">

</div>
<div class="form-group col-sm-4 col-xs-6">
<label>Address 3</label>
{!! Form::text('Address3','',array('class' => 'form-control' ,'id' => 'Address3' , "placeholder" => 'Landmark')) !!}
</div>
<div class="form-group col-sm-3 col-xs-6">

</div>
<div class="form-group col-sm-3 col-xs-6">

<br clear="all">
@if(Session::has('successs'))
<div class="alert text-center alert-success" style="font-size:12px;">
{!!Session::get('successs')!!}
</div>
@endif
@if(Session::has('error'))
<div class="alert alert-danger">
{!!Session::get('error')!!}
</div>
@endif
</h1>
</div>
</div>
{!! Form::close() !!}
然后在编辑链接中，我已经编写了代码
<a href="<?php echo 'Editstaff/'.$row->staff_id; ?>" class="btn btn-xs btn-info" >Edit</a>
然后在路由文件中，我编写了这样的代码
Route::get('Editstaff/{id}', 'HomeController@Editstaff');
然后在控制器文件中，我编写了类似
public function Editstaff($id)
{
$editdata = DB::table('staff')->where('staff_id','=',$id)->first();
return View::make('staff',array('list' => $editdata));
}
我想更新数据首先显示从单击编辑链接开始..有人可以帮助我吗？
首先要做的是：你正在使用一个表单，以我的拙见，id应该放在表单的隐藏字段中......无论如何，您可以通过$request变量访问表单数据。更改方法的签名，如下所示：
public function Editstaff(Request $request, $id)
并记住在控制器的头部包含 Illuminate''Http''Request 类和 use 语句（显然在命名空间之后）。
使用给定的 ID 加载记录，如下所示：
$staff = Staff::find($id);
考虑使用 Staff：：findOrFail（$id），如果找不到给定 id 的记录，则（如方法名称所示）将失败。下一步包括在获取的模型上设置数据，就像插入一样：
$staff->myField = $request->input('myField');
然后调用模型的保存方法
$staff->save()
还有另一种方法可以达到相同的目标。在此处查看Laravel文档以获取有关保存和更新模型的更多信息。你也应该在这里查看响应章节
路线
Route::get('Editstaff/{id}', 'HomeController@Editstaff');
控制器
public function Editstaff(Request $request)
{
$editdata = array(
$title = $request->input('title');
);
DB::table('staff')->where('id', $id)->update($editdata );
Session::flash('message', 'Data update successfully');
return redirect('addstaff');
}
