[php] Laravel 5 Class 'form' not found

I have added "illuminate/html": "5.*" to composer.json and ran "composer update".

  - Installing illuminate/html (v5.0.0)
    Loading from cache

I ran this command in the root of the website. I modified the composer.json file in /root/.composer... and in the root of the project and neither have made a difference.

This downloaded the class and it seemed to install. I have added the following to file config/app.php.

    'Illuminate\Html\HtmlServiceProvider',

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

I think I have an idea what is wrong, but I don’t know how to fix it. My install is in '/var/www/website'. I have checked the file path and the Html folder does not exist.

"/var/www/website/vendor/laravel/framework/src/Illuminate/Html"

I was able to find the class files, but in a different directory.

"/var/www/website/vendor/illuminate/html"

I manually copied the files over to the main Laravel illuminate/html folder, but this hasn't worked either.

You can also try running the following commands in Terminal or Command:

1. composer dump-auto or composer dump-auto -o
2. php artisan cache:clear
3. php artisan config:clear

The above worked for me.

In Laravel Version - 4, HTML and Form existed, but not now.

Why:

The only reason is they have collected some user requirements and they want it more lightweight and so they removed it as in the sense that a 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: on the command line, run the command

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

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

Collective\Html\HtmlServiceProvider::class,

For using HTML and FORM text we need to alias them in the aliases array of config/app.php. Add the two lines 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 the 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 a 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/.

Just type the following command in terminal at the project directory and installation is done according the Laravel version:

composer require "laravelcollective/html"

Then add these lines in config/app.php

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

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

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

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

"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

Update Laravel 5.8 (2019-04-05):

In Laravel 5.8, the providers in the config/app.php can be declared as:

Collective\Html\HtmlServiceProvider::class,

instead of:

'Collective\Html\HtmlServiceProvider',

This notation is the same for the aliases.

There is an update to this for Laravel 5.2. Notice this is a slightly different format from what is indicated above.

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

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

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::class,
    // ...
  ],

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

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

After making this update this code worked for me on a new installation of Laravel 5.2:

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

I got this information here: https://laravelcollective.com/docs/5.2/html

Use Form, not form. The capitalization counts.

I have tried everything, but only this helped:

php artisan route:clear
php artisan cache:clear

Begin by installing this package through Composer. Run the following from the terminal:

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

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

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

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

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