在 laravel 5.2 中找不到类“表单”

Question

我已按照此处类似问题中的回答执行了这些步骤，但是我没有得到解决方案：

1. 编辑composer.json添加：

   "require": { "laravelcollective/html": "5.2.*" }

2. 从终端更新作曲家：

   composer update

3. 接下来，将您的新提供者添加到 config/app.php 的 providers 数组中：

'providers' => [ // ... Collective\Html\HtmlServiceProvider::class, // ... ],

最后在config/app.php的aliases数组中添加两个类别名：

  'aliases' => [
    // ...
      'Form' => Collective\Html\FormFacade::class,
      'Html' => Collective\Html\HtmlFacade::class,
    // ...
  ],

错误是：

94130ac18d8152bd785794934f1ccfb5f9a84201.php 中的致命错误异常 第 18 行：找不到类“表单”

查看文件为index.blade.php

@section('main')

<h1>All Users</h1>

<p><a href={{ url('users\create') }}>Add new user</a></p>

@if ($users->count())
    <table border="2">
<tr><td>s.n.</td><td>name</td><td>email</td><td>options</td>
            @foreach ($users as $user)
           <tr>
<td>{{ $user->id }}</td>
        <td>{{ $user->name }}</td>
    <td>{{ $user->email }}</td>
                    <td><a href={{ url('users\{id}\edit', $user->id)}}>Edit</a>

<td>
          {{ Form::open(array('method' => 'DELETE', 
        'route' => array('users.destroy', $user->id))) }}                       
                            {{ Form::submit('Delete', array('class' => 'btn btn-danger')) }}
                        {{ Form::close() }}
                    </td>                
</tr>
      @endforeach


    </table>
@else
    There are no users
@endif

@stop

Answer 1

使用这些命令：

composer dump-autoload -o
php artisan route:clear
php artisan cache:clear
php artisan config:cache
php artisan route:cache

另外，请尝试在任何地方使用{!! Form:: !!} 而不是{{ Form:: }}。

Answer 2

使用以下步骤对我有用。

步骤：

1) 打开 composer.json 文件并将以下行添加到 require.

"laravelcollective/html": "5.2.*",

所以它看起来像：

"require": {
    "php": ">=5.5.9",
    "laravel/framework": "5.2.*",
    "laravel/socialite": "^2.0",
    "illuminate/html": "5.*",
    "laravelcollective/html": "5.2.*",
    "intervention/image": "dev-master"
},

2) 现在运行 composer update 命令来获取包。

composer update

2) 打开 App/config/app.php 文件，将以下行添加到 providers 和 aliases 数组中。

到提供者数组：

Collective\Html\HtmlServiceProvider::class,

到别名数组：

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

Answer 3

从 Laravel 5 及更高版本中删除了 HTML 和 FORM 助手
但是，您仍然可以在最新的 Laravel 中使用它。

首先，使用命令提示符在项目文件夹中使用 composer 安装 laravelcollective/html：

composer require laravelcollective/html

在 config/app.php

中添加以下行

'providers' => [
    // ...
    Collective\Html\HtmlServiceProvider::class,
    // ...
],

和，

'aliases' => [
// ...
   'Form' => 'Collective\Html\FormFacade',
   'Html' => 'Collective\Html\HtmlFacade',
// ...
],
