Edit and Updating Data in Laravel
提问by RodnovryJoshua
I am having some trouble editing data in Laravel. Here's the button to show Edit view:
我在 Laravel 中编辑数据时遇到了一些问题。这是显示编辑视图的按钮：
{{ Form::open(array('route' => array('edit_spk', 'id'=> $spk_data->id), 'method' => 'GET', 'style' => 'display:inline')) }}
<button class="btn btn-success btn-line btn-rect">
<i class="icon-pencil icon-white"></i> Edit
</button>
{{Form::close()}}
Here's the route:
这是路线：
Route::get('spk/edit/{id}', array('as'=>'edit_spk','uses'=>'SpkController@edit'));
Route::put('spk/update/{id}', array('as'=>'update_spk','uses'=>'SpkController@update'));
Here's the controller:
这是控制器：
public function edit($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');
}
}
And here's the View for update the data :
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>

This view doesn't work and it can't get the selected data from $idinto the form. It is returning this error:
此视图不起作用，它无法将所选数据从$id表单中获取。它正在返回此错误：
"Undefined property: Illuminate\Database\Eloquent\Collection::$id (View: C:\XAMPP\htdocs\ims2\app\views\modals\edit-spk.blade.php)"
“未定义的属性：Illuminate\Database\Eloquent\Collection::$id（视图：C:\XAMPP\htdocs\ims2\app\views\modals\edit-spk.blade.php）”

Can you dd($spk)after $spk = Spk::find($id);in the edit method and paste the output.
你可以在编辑方法dd($spk)后$spk = Spk::find($id);粘贴输出。
Edit:
编辑：
The button should look like this (no form)
该按钮应如下所示（无形式）
<a href="{{ route('edit_spk', ['id' => $spk_data->id]) }}" class="btn btn-success btn-line btn-rect">
<i class="icon-pencil icon-white"></i> Edit
</a>
The controller:
控制器：
public function edit($id){
$spk = Spk::find($id);
return View::make('modals.edit-spk', [
'spk' => $spk
]);
}
Try this and let me know if the error persists. If so, is it the same exact error? If not, please paste the new one.
试试这个，如果错误仍然存在，请告诉我。如果是这样，它是完全相同的错误吗？如果没有，请粘贴新的。

About the error:
关于错误：
In your view, you've got this piece of code
在你看来，你已经得到了这段代码
{{ Form::open(array('route' => array('edit_spk', 'id'=> $spk_data->id), 'method' => 'GET', 'style' => 'display:inline')) }}
the $spkvariable is an eloquent collection, that is returned on your controller. You're accessing $spk->id, which is incorrect, need to access the a single element in the collection in order to edit it
该$spk变量是一个雄辩的集合，它在您的控制器上返回。您正在访问 $spk->id，这是不正确的，需要访问集合中的单个元素才能对其进行编辑
Allow me to simplify your code in the meanwhile:
同时，请允许我简化您的代码：
In your route, you specify what method in the controller will handle the request. Write in your console:
在您的路由中，您指定控制器中将处理请求的方法。在您的控制台中写入：
php artisan make:request SpkContent
SpkController
控制器
use App\Http\Requests\SpkContent;
public function edit($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
SpkContent 表单请求
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;
}
}
At least, this way you can split validation from operation, much cleaner and maintainable code
至少，通过这种方式，您可以将验证与操作分开，代码更加简洁和可维护
