Question

我不明白为什么它不起作用并让我犯错误

这是我的表格

{!! Form::open(['method' => 'PUT', 'route' => ['admin.project.edit', $project->slug, 'files' => 'true']]) !!}

                      <div class="form-group{{ $errors->has('title') ? ' has-error' : '' }}">
                    {!! Form::label('title', 'Title') !!}
                    {!! Form::text('title', $project->title, ['class' => 'form-control', 'required' => 'required']) !!}
                    <small class="text-danger">{{ $errors->first('title') }}</small>
                </div>
                <div class="form-group{{ $errors->has('content') ? ' has-error' : '' }}">
                    {!! Form::label('content', 'Content') !!}
                    {!! Form::textarea('content', $project->content, ['class' => 'form-control', 'required' => 'required']) !!}
                    <small class="text-danger">{{ $errors->first('content') }}</small>
                </div>

                @if($project->progress == 1)
                <div class="radio{{ $errors->has('progress') ? ' has-error' : '' }}">

                  {!! Form::close() !!}

我的管理员小组

public function projectedit($id, Request $request){

    $this->validate($request, [
        'title' => 'required|max:255',
        'content' => 'required|max:10000',
        'image' => 'mimes:jpeg,bmp,png,jpg',
    ]);

    $project = Project::where('slug', $id)->firstorfail();
    $project->title = $request->title;
    $project->slug = str_slug($project->title, '-');
    $project->content = $request->content;
    $project->progress = $request->progress;
    if($request->hasFile('image')) {
        $file = Input::file('image');
        //getting timestamp
        $timestamp = str_replace([' ', ':'], '-', Carbon::now()->toDateTimeString());
        $name = $timestamp. '-' .$file->getClientOriginalName();
        $file->move(public_path().'/images/project/', $name);
        $project->image = $name;
        $thumb = Image::make(public_path().'/images/project/' . $name)->resize(1200,500)->save(public_path().'/images/project/thumb/' . $name, 60);
    }
    $project->save();
    return Redirect::back()->with('status', 'Project Edit Success');

}

请告诉我我做错了什么一切正常但图像没有上传而不上传图片，否则一切正常。

Answer 1

你应该设置

'files' => 'false'

至

'files' => 'true'

在表格的第1行

Answer 2

更改以下行：

{!! Form::open(['method' => 'PUT', 'route' => ['admin.project.edit', $project->slug, 'files' => 'false']]) !!}

对此：

{!! Form::open(['method' => 'PUT', 'route' => ['admin.project.edit', $project->slug], 'files' => 'true']) !!}

而你上传图像的方式相当混乱，它在控制器中看起来如何使用Laravel Filesystem呢？

更改config / filesytems.php中的以下行：

'local' => [
     'driver' => 'local',
     'root' => storage_path('app'),
],

对此：

'local' => [
     'driver' => 'local',
     'root' => public_path(),
],

然后在控制器中你可以这样做：

public function projectedit($id, Request $request){
    $this->validate($request, [
        'title' => 'required|max:255',
        'content' => 'required|max:10000',
        'image' => 'mimes:jpeg,bmp,png,jpg',
    ]);

    $project = Project::where('slug', $id)->firstorfail();
    $project->title = $request->title;
    $project->slug = str_slug($project->title, '-');
    $project->content = $request->content;
    $project->progress = $request->progress;
    if($request->hasFile('image')) {
        $project->image = $request->file('image')->store('images/project');
    }
    $project->save();
    return Redirect::back()->with('status', 'Project Edit Success');
}

清洁吧？ :)

Answer 3

在您设置的表单创建代码中：

['files' => 'false']

这会限制文件上载，当您将其更改为true时，生成的表单将具有编码类型

enctype= multipart/form-data laravel

Answer 4

在表单中将'files'=>'false'设置为'files'=>'true'。

并检查你的php.ini文件中的file_upload = on;

Answer 5

请更改您的表单方法，如：

{!! Form::open(['method' => 'PUT', 'route' => ['admin.project.edit', $project->slug, 'files' => 'false']]) !!}

至

{!! Form::open(['method' => 'POST', 'route' => ['admin.project.edit', $project->slug, 'files' => 'true']]) !!}
