问题
I am upgrading from 4.2 directly to 5.1 and run into problems with the Html and Form classes.
I followed the upgrade notes, and did
- 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
But my views don't work. I get either Class HTML does not exist when using HTML::router or get Class html does not exist when using link_to_route
I also tried Illuminate\html instead of laravelcollective, I did a composer dump-autoload.
The complete errors:
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?
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.
回答1:
Add in composer.json
"illuminate/html": "5.*"
and run composer update
Open your config/app.php
add under 'providers'
Illuminate\Html\HtmlServiceProvider::class,
add under 'aliases'
'Form' => Illuminate\Html\FormFacade::class,
'Html' => Illuminate\Html\HtmlFacade::class,
and under your blade templates, use as such
{!! HTML::style('assets/css/flatten.css') !!}
回答2:
My solution in my case it was problem with CASE-Sensitive class name.
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:
{!! HTML::mailto('mailto:example@example.com', 'example@example.com'); !!}
and that was an error:
"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.
Hope this help for some people.
回答3:
Please change your blade file from this
{{ HTML::style('css/bootstrap.min.css') }}
to
{{ Html::style('css/bootstrap.min.css') }}
It's working.
回答4:
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.
回答5:
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).
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.
So, now everything is working, I simply renamed my new application and can continue.
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.
回答6:
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/
回答7:
I think I have found the solution.
In your app.php you have declared
'Form' => Illuminate\Html\FormFacade::class,
'Html' => Illuminate\Html\HtmlFacade::class,
While in your View you have called the same class as
{!! 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 HTML as the previous documentation ver 5.0.*.
It should be
'Form' => Illuminate\Html\FormFacade::class,
'HTML' => Illuminate\Html\HtmlFacade::class,
回答8:
Try it
php artisan cache:clear
php artisan clear-compiled
回答9:
edit config/app.php
add this into providers
Collective\Html\HtmlServiceProvider::class,
and this into aliases
'Form' => Collective\Html\FormFacade::class,
'Html' => Collective\Html\HtmlFacade::class,
