这是我的Comp

{

我运行作曲家更新命令。

这是我的app.php

在formupload.blade.php中使用表单

@if(isset($success))
    <div class="alert alert-success"> {{$success}} </div>
@endif
    {!! Form::open(['action'=>'ImageController@store', 'files'=>true]) !!}

    <div class="form-group">
        {!! Form::label('title', 'Title:') !!}
        {!! Form::text('title', null, ['class'=>'form-control']) !!}
    </div>

    <div class="form-group">
        {!! Form::label('description', 'Description:') !!}
        {!! Form::textarea('description', null, ['class'=>'form-control', 'rows'=>5] ) !!}
    </div>

    <div class="form-group">
        {!! Form::label('image', 'Choose an image') !!}
        {!! Form::file('image') !!}
    </div>

    <div class="form-group">
        {!! Form::submit('Save', array( 'class'=>'btn btn-danger form-control' )) !!}
    </div>

    {!! Form::close() !!}
    <div class="alert-warning">
        @foreach( $errors->all() as $error )
           <br> {{ $error }}
        @endforeach
    </div>

</div>

Answer 1

运行命令

 composer require laravelcollective/html

当作曲家更新需要的html laravel集体，然后将这两行添加到配置/app.php到
别名的部分=

'Form' => Collective\Html\FormFacade::class,
'Html' => Collective\Html\HtmlFacade::class,

然后将该行添加到config/app.php
“providers”=

Collective\Html\HtmlServiceProvider::class,

Answer 2

看起来您在app.php中将表单类的别名设置为“表单”：

“表单”=

尝试将其更改为表单，如下所示：

'Form'=

那应该能行

Answer 3

把这个放进composer.json

"require": {
        "laravelcollective/html": "^5.4"
 },

然后跑

composer update 

事后指挥

或

composer require laravelcollective/html

然后将其添加到config/app.php的providers部分数组中

Collective\Html\HtmlServiceProvider::class,

之后添加两个类别名在配置/app.php在别名数组

'Form' => Collective\Html\FormFacade::class,
'Html' => Collective\Html\HtmlFacade::class,
