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">

Laravel 5 Class 'form' not found的可能重复
请展示这些“最大努力”，首先展示一些代码和预期结果
看看这个link
R. Manzarei 先生您好，此链接仅适用于 5.3 版本我目前使用的是 5.4.17 版本的 laravel
嗨@Shogunivar我已经添加了“require”：{“laravelcollective/html”：“^5.4”}，添加到composer.json并添加了'providers'=> [''Collective\Html\HtmlServiceProvider ',] & 添加到别名 'FORM' => 'Collective\Html\FormFacade', 'HTML' => 'Collective\Html\HtmlFacade'，在 app.php 中也可以在 cmd 中运行 composer update 命令

标签： forms laravel

【解决方案1】：

把它放在composer.json中

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

然后运行

composer update

事后指挥

或者

composer require laravelcollective/html

然后将其添加到您的 config/app.php 的 providers 部分数组中

Collective\Html\HtmlServiceProvider::class,

然后在别名数组的config/app.php中添加两个类别名

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

【讨论】：

【解决方案2】：

看起来您在 app.php 中将表单类的别名设置为“FORM”：

'FORM' => 'Collective\Html\FormFacade',

尝试将其更改为 Form，如下所示：

'Form' => 'Collective\Html\FormFacade',

那么它应该可以工作

【讨论】：

嗨@Shogunivar 感谢您给我正确的答案。是的，它工作正常。它的正确答案。再次感谢您的大力帮助。

【解决方案3】：

运行命令

 composer require laravelcollective/html

当作曲家更新 require html laravel 集合时然后将这两行添加到 config/app.php 的
'aliases' => [ ],

部分

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

然后将该行添加到 config/app.php
'providers' => [ ], 并保存文件

Collective\Html\HtmlServiceProvider::class,

【讨论】：

【解决方案4】：

运行命令

composer require laravelcollective/html

将这两行添加到 config/app.php 的部分 'aliases' => [ ],

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

将该行添加到 config/app.php 'providers' => [ ]，然后保存文件

Collective\Html\HtmlServiceProvider::class,

这也适用于 6.X

【讨论】：

【解决方案5】：

config/app.php 中的类别名

'Form' => 'Collective\Html\FormFacade',

这对我有用
