Question

我在Laravel中编辑数据时遇到了一些麻烦。这是显示编辑视图的按钮：

{{ Form::open(array('route' => array('edit_spk', 'id'=> $spk_data->id), 'method' => 'GET', 'style' => 'display:inline')) }}
<button class="btn btn-success btn-line btn-rect">
  <i class="icon-pencil icon-white"></i> Edit
</button>
{{Form::close()}}

这是路线：

Route::get('spk/edit/{id}', array('as'=>'edit_spk','uses'=>'SpkController@edit'));
Route::put('spk/update/{id}', array('as'=>'update_spk','uses'=>'SpkController@update'));

这是控制器：

public function edit($id){
  $spk = Spk::find($id);
  $spk->distribution_code=Input::get('distribution_code');
  $spk->destination=Input::get('destination');
  $spk->hlr=Input::get('hlr');
  $spk->first_iccid=Input::get('first_iccid');
  $spk->last_iccid=Input::get('last_iccid');
  $spk->quantity=Input::get('quantity');
  return View::make('modals.edit-spk', compact('spk'));
}

public function update($id) {
  $rules = array(
    'distribution_code' => 'required',
    'destination' => 'required',
    'hlr'=> 'required',
    'first_iccid' => 'required',
    'last_iccid' => 'required',
    'quantity' => 'required'
  );

  $validator = Validator::make(Input::all(), $rules);

  if ($validator->fails()) {
    return Redirect::to('modals.edit-spk')->withErrors($validator);
  } else {
    // store
    $update = Spk::find($id);
    $update->distribution_code=Input::get('distribution_code');
    $update->destination=Input::get('destination');
    $update->hlr=Input::get('hlr');
    $update->first_iccid=Input::get('first_iccid');
    $update->last_iccid=Input::get('last_iccid');
    $update->quantity=Input::get('quantity');
    $update->save();

    // redirect
    Session::flash('message', 'Successfully updated SPK !');
    return Redirect::to('spk_view');
  }
}

这是用于更新数据的视图：

@extends('dashboard.dashboard')
@section('content')
@if (Session::has('message'))
<div class="alert alert-info">{{ Session::get('message') }}</div>
@endif
<h4> {{link_to('dashboard','Home');}} > {{link_to('spk_view','SPK');}} > Update SPK</h4><hr></hr>
<div class="panel panel-default">
    <div class="panel-heading">
        Update SPK
    </div>
    <div class="panel-body">
        {{ Form::model($spk,array('method' => 'PUT', 'class'=>'form-horizontal','route'=>array('update_spk', $spk->id))) }}
        <div class="form-group">

此视图不起作用，无法将$id中的选定数据导入表单。它返回了这个错误：

“Undefined property：Illuminate \ Database \ Eloquent \ Collection :: $ id（查看：C：\ XAMPP \ htdocs \ ims2 \ app \ views \ modals \ edit-spk.blade.php）”

Answer 1

您可以在编辑方法dd($spk)之后$spk = Spk::find($id);粘贴输出。

编辑：

按钮应如下所示（无形式）

<a href="{{ route('edit_spk', ['id' => $spk_data->id]) }}" class="btn btn-success btn-line btn-rect">
    <i class="icon-pencil icon-white"></i> Edit
</a>

控制器：

public function edit($id){
    $spk = Spk::find($id);
    return View::make('modals.edit-spk', [
        'spk' => $spk
    ]);
}

试试这个，如果错误仍然存在，请告诉我。如果是这样，它是否是同样的错误？如果没有，请粘贴新的。

Answer 2

关于错误：

您认为您已经获得了这段代码

{{ Form::open(array('route' => array('edit_spk', 'id'=> $spk_data->id), 'method' => 'GET', 'style' => 'display:inline')) }}

$spk变量是一个雄辩的集合，它在控制器上返回。您正在访问$ spk-> id，这是错误的，需要访问集合中的单个元素才能对其进行编辑

同时让我简化您的代码：

在路由中，您指定控制器中的哪种方法将处理请求。在控制台中编写：

php artisan make:request SpkContent

SpkController

use App\Http\Requests\SpkContent;

public function edit($id, SpkContent $request){

  $spk = Spk::find($id);
  //Not sure what this is for really, but you can simplify the lines below with this one
  //$data = $request->validated();
  //$spk = array_merge($spk->toArray(), $data);
  $spk->distribution_code=Input::get('distribution_code');
  $spk->destination=Input::get('destination');
  $spk->hlr=Input::get('hlr');
  $spk->first_iccid=Input::get('first_iccid');
  $spk->last_iccid=Input::get('last_iccid');
  $spk->quantity=Input::get('quantity');
  return View::make('modals.edit-spk', compact('spk'));
}

public function update($id, SpkContent $request) {
    // store
    $data = $request->validated();
    Spk::findOrFail($id)->update($data);

    // redirect
    Session::flash('message', 'Successfully updated SPK !');
    return Redirect::to('spk_view');
}

SpkContent FormRequest

class SpkContent extends FormRequest
{
    public function authorize()
    {
        return true;
    }

    public function rules()
    {
        //Add whatever validations you need, as in: max size, integers, etc
        $content = [
         'distribution_code' => 'required',
         'destination' => 'required',
         'hlr'=> 'required',
         'first_iccid' => 'required',
         'last_iccid' => 'required',
         'quantity' => 'required'
        ];
        return $content;
    }
}

至少，通过这种方式，您可以将验证与操作，更简洁，可维护的代码分开
