Laravel 5.1：类 html 不存在

Laravel 5.1: Class html does not exist

提问by Michiel van der Blonk

I am upgrading from 4.2 directly to 5.1 and run into problems with the Html and Form classes.

我正在从 4.2 直接升级到 5.1，但遇到了 Html 和 Form 类的问题。

I followed the upgrade notes, and did

我遵循了升级说明，并做到了

• add "laravelcollective/html": "~5.0" to composer.json
• composer update
• add Collective\Html\HtmlServiceProvider::class to providers in app.php
• add Form' => Collective\Html\FormFacade::class, Html' => Collective\Html\HtmlFacade::class to aliases in app.php

• 将 "laravelcollective/html": "~5.0" 添加到 composer.json
• 作曲家更新
• 将 Collective\Html\HtmlServiceProvider::class 添加到 app.php 中的提供者
• 添加 Form' => Collective\Html\FormFacade::class, Html' => Collective\Html\HtmlFacade::class 到 app.php 中的别名

But my views don't work. I get either Class HTML does not existwhen using HTML::router or get Class html does not existwhen using link_to_route

但我的观点行不通。我要么Class HTML does not exist在使用 HTML::router 时得到，要么Class html does not exist在使用 link_to_route 时得到

I also tried Illuminate\htmlinstead of laravelcollective, I did a composer dump-autoload.

我也尝试过，Illuminate\html而不是laravelcollective，我做了一个composer dump-autoload.

The complete errors:

完整的错误：

ErrorException in Container.php line 736: Class html does not exist (View: C:\Dev\www\admin\resources\views\clubs\index.blade.php)
ReflectionException in Container.php line 736: Class html does not exist

What am I missing?

我错过了什么？

I tried everyone's answers and none of them worked for me for some reason. Ultimately I created a completely new laravel application, copied my code and then it started working, So though solved the actual problem remains a mystery.

我尝试了每个人的答案，但出于某种原因，没有一个对我有用。最终我创建了一个全新的 Laravel 应用程序，复制了我的代码然后它开始工作，所以虽然解决了实际问题仍然是一个谜。

My problem is solved, but the actual cause is still unknown. I have created a completely new laravel install and copied my source (all of it). The new application worked right away (after installing illuminate/html).

我的问题已解决，但实际原因仍然未知。我已经创建了一个全新的 laravel 安装并复制了我的源代码（全部）。新应用程序立即运行（在安装illuminate/html 之后）。

So you think I did something wrong with packages? That's what I thought, and then I did a diff on the two directories, only to find out they were identical. So it's a real mystery.

所以你认为我在包裹上做错了什么？我就是这么想的，然后我对这两个目录进行了比较，结果发现它们是相同的。所以这是一个真正的谜。

So, now everything is working, I simply renamed my new application and can continue.

因此，现在一切正常，我只需重命名我的新应用程序即可继续。

I do know at some point I probably had both the collective and the illuminate versions of the HTML package installed. That's what most likely corrupted everything.

我确实知道在某些时候我可能同时安装了 HTML 包的集体版本和说明版本。这就是最有可能破坏一切的原因。

Add in composer.json

在 composer.json 中添加

 "illuminate/html": "5.*"

and run composer update

并运行作曲家更新

Open your config/app.php

打开你的 config/app.php

add under 'providers'

在“提供者”下添加

Illuminate\Html\HtmlServiceProvider::class,

add under 'aliases'

在“别名”下添加

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

and under your blade templates, use as such

并在您的刀片模板下，按原样使用

{!! HTML::style('assets/css/flatten.css') !!}

回答by Yurii Svystun

My solution in my case it was problem with CASE-Sensitive class name.

我的解决方案是 CASE-Sensitive 类名有问题。

In my config/app.php (in aliases)
'Form'      => Collective\Html\FormFacade::class,
'Html'      => Collective\Html\HtmlFacade::class,

I am tried to use in view this code:

我试图在查看此代码时使用：

{!! HTML::mailto('mailto:[email protected]', '[email protected]'); !!}

and that was an error:

这是一个错误：

"FatalErrorException in ccf70b1d0b9930d6c4e8f3859fff448f line 11: Class 'HTML' not found"

Name of class 'HTML' is CASE-Sensitive. You should use 'Html' as in your config (config/app.php) file.

“HTML”类的名称区分大小写。您应该在配置 (config/app.php) 文件中使用“Html”。

Hope this help for some people.

希望这对某些人有所帮助。

回答by shijinmon Pallikal

Please change your blade file from this

请从此更改您的刀片文件

{{ HTML::style('css/bootstrap.min.css') }}

to

到

{{ Html::style('css/bootstrap.min.css') }}

It's working.

它正在工作。

A simple restart after composer update worked perfectly for me. I was looking for the answer, and got stuck at the same position. I'd suggest, run config:cache and cache:clear and restart the IDE. It will work.

作曲家更新后的简单重启对我来说非常有效。我一直在寻找答案，却卡在了同一个位置。我建议，运行 config:cache 和 cache:clear 并重新启动 IDE。它会起作用。

I think I have found the solution.

我想我已经找到了解决办法。

In your app.phpyou have declared

在app.php你已经声明

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

While in your Viewyou have called the same class as

在你的时候，View你已经调用了相同的类

{!! HTML::style('css/bootstrap.min.css') !!}

There is nothing wrong with the packages as the marked answer above but rather difference in capitalization of the word HTMLas the previous documentation ver 5.0.*.

作为上述标记答案的包没有任何问题，但HTML与之前的文档版本 5.0.* 相比，单词的大小写有所不同。

It should be

它应该是

'Form'      => Illuminate\Html\FormFacade::class,
'HTML'      => Illuminate\Html\HtmlFacade::class,

回答by EricZ

edit config/app.php

编辑config/app.php

add this into providers

将此添加到提供程序中

Collective\Html\HtmlServiceProvider::class,

and this into aliases

并将其转换为别名

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

回答by channasmcs

this is right way If you try to use Form::open() or any of the Form methods in a fresh Laravel 5 install, you would get something like this: http://laraveldaily.com/class-form-not-found-in-laravel-5/

这是正确的方法如果您尝试在新的 Laravel 5 安装中使用 Form::open() 或任何 Form 方法，您会得到如下内容：http://laraveldaily.com/class-form-not-found -in-laravel-5/
