我无法在我的控制器中编辑我这样创建的项目：
public function newProject(Request $request)
{
$data = $request->all();
$attributes = [];
$attributes['title'] = $data['title'];
$attributes['start_date'] = date("Y-m-d h:i:s", strtotime($data['start_date']));
$attributes['end_date'] = date("Y-m-d h:i:s", strtotime($data['end_date']));
$attributes['created_by'] = Auth::user()->id;
$attributes['description'] = $data['description'];
$attributes['air'] = '10';
$attributes['water'] = '19';
$attributes['lat'] = $data['lat'];
$attributes['lng'] = $data['lng'];
// var_dump($attributes);
// return;
$project = Projects::create($attributes);
if($project)
return redirect('home')->with('success', 'Project added successfully');
var_dump($data);
return;
}
现在，我想编辑我使用上述功能创建的项目。我尝试了相同的程序只是改变路线：
Route::post('projects/new', [
'uses' => 'ProjectsController@newProject',
'as' => 'projects.new',
]);
注意：这是我创建项目的功能和路线。有什么提示如何编辑？

我建议采用简单方法
控制器功能
public function update($id, Request $request)
{
$data = $request->all();
$project = Projects::findOrFail($id);
$project->update($data);
return redirect(/home);
}
<强>路线
Route::patch('projects/{id}', [ // this is the project id
'uses' => 'ProjectsController@update',
'as' => 'projects.update',
]);
表格（假设您使用的是laravel集体表格）
{!! Form::model($project, [
'method' => 'PATCH',
'url' => ['/project', $project->id], // this is where you submit the id of the project
'class' => 'form-horizontal',
'files' => true
]) !!}
<div class="form-group {{ $errors->has('name') ? 'has-error' : ''}}">
{!! Form::label('name', 'Name', ['class' => 'col-sm-3 control-label']) !!}
<div class="col-sm-6">
{!! Form::text('name', null, ['class' => 'form-control']) !!}
{!! $errors->first('name', '<p class="help-block">:message</p>') !!}
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-3 col-sm-3">
{!! Form::submit('Update', ['class' => 'btn btn-primary form-control']) !!}
</div>
</div>
{!! Form::close() !!}
这是最好的方式！我不建议使用相同的功能，除非你确定你想要的。
<强>更新
<form class="form-horizontal" role="form" method="POST" action="{{ url('projects', $project->id) }}">
{{ csrf_field() }}
<input name="_method" type="hidden" value="PATCH"> // add this
// here you put the rest of the form
</form>
如果您没有此$project变量可用
请告诉我显示编辑页面的功能
因为我需要知道你将如何传递你想要更新的项目的ID（用户输入与否）
答案 1 :(得分：0)
您可以在一个功能中完成所有操作：
public function storeOrUpdate(Request $request) {
try{
DB::transaction(function() use($request) {
Projects::firstOrNew([
'id' => $request->has('id') ? $request->get('id') : null
'title' => $request->get('title'),
'start_date' => $request->has('start_date') ? Carbon\Carbon::parse($request->get('start_date')) ? null,
'end_date' => $request->has('end_date') ? Carbon\Carbon::parse($request->get('end_date')) ? null,
'created_by' => auth()->user()->id,
'description' => $request->get('description'),
'air' => 19,
'water' => 10,
'lat' => $request->get('lat'),
'lng' => $request->get('lng')
]);
});
DB::commit();
return redirect('home')->with('Success', 'Project added successfully');
} catch (\Exception $e){
DB::rollback();
return redirect()->back()->withErrors(collect($e->getMessage())->toArray);
}
});
