Class 'Form' not found clas Form not found

Form isn't included in laravel 5.0 as it was on 4.0, steps to include it:

Begin by installing this package through Composer. Edit your project's composer.json file to require laravelcollective/html

"require": {
    "laravelcollective/html": "~5.0"
}

Next, update composer from the Terminal:

composer update

Next, add your new provider to the providers array of config/app.php:

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

Finally, add two class aliases to the aliases array of config/app.php:

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

At this point, Form should be working

您还可以尝试在终端或命令中运行以下命令：
1. composer dump-auto或composer dump-auto -o 
2. php artisan cache:clear 
3。php artisan config:clear

以上为我工作

Laravel 5.2有一个更新。请注意，这是与上述不同的格式。

首先通过Composer安装这个包。编辑您的项目的composer.json文件以要求laravelcollective / html。

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

接下来，从终端更新Composer：

作曲家更新接下来，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，将两个类别别添加到config / app.php的别名数组中：

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

在进行此更新后，此代码对我的Laravel 5.2的新安装有效：

{!! Form::open(array('url' => 'foo/bar')) !!}
    //
{!! Form::close() !!}

我在这里获得了这些信息：https：//laravelcollective.com/docs/5.2/html

Form不使用form，资本化数量。

首先通过Composer安装这个包。从终端运行以下命令：

composer require "laravelcollective/html":"^5.3.0"

接下来，将您的新提供程序添加到config / app.php的providers数组中：

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

最后，将两个类别别添加到config / app.php的别名数组中：

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

在Laravel Version - 4中，HTML＆Form已存在，但现在不存在。

为什么

Only reason is they have collected some user requirements and they want it more lightweight and so they removed it as this sense that user can add it manually.

What to do to add HTML & Forms in Laravel 5.2 or 5.3:

For 5.2:

Go to the Laravel Collective site and installation processes have demonstrated their.

Like for 5.2: in command line run the command

composer require "laravelcollective/html":"^5.2.0"

Then, in provider array which is in config/app.php. Add this line at last using a comma(,)

Collective\Html\HtmlServiceProvider::class,

For use HTML and FORM text we need to aliases them in aliases array of config/app.php. Add the two line at the last

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

And for 5.3:

Just run the command

composer require "laravelcollective/html":"^5.3.0"

And rest of the procedure is like 5.2

Then you can use Laravel Form and other HTML links in your projects. For this follow this documentation:

5.2 : https://laravelcollective.com/docs/5.2/html

5.3: https://laravelcollective.com/docs/5.3/html

Demo Code : To open a form open and close tag :

{!! Form::open(['url' => 'foo/bar']) !!}

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

And for creating label and input text with a bootstrap form-control class and other use :

{!! Form::label('title', 'Post Title') !!}
{!! Form::text('title', null, array('class' => 'form-control')) !!}

And for more, use the documentation https://laravelcollective.com/

composer require "laravelcollective/html"

just type this command in terminal at project directory and installation is done according laravel version and don't forget to add this lines in app.php under config folder

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

],

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

],
