"How to fix 'class not found' error in Laravel" - laravel

Question

I need to create a form in Laravel. When I open the localhost it shows this error
"Class 'Collective\Html\FormFacade' not found (View: C:\xampp\htdocs\softwareProject\test\resources\views\studentForm.blade.php)"
How to fix this?

Answer 1

You need to edit composer.json file to require laravelcollective/html
By using composer in your terminal or command prompt type the following:
composer require "laravelcollective/html":"^5.4.0"
Second, add this provider to the providers array of config/app.php as below:
'providers' => [
// ...
Collective\Html\HtmlServiceProvider::class,
// ...
],
And finally add two class aliases to the aliases array of config/app.php:
'aliases' => [
// ...
'Form' => Collective\Html\FormFacade::class,
'Html' => Collective\Html\HtmlFacade::class,
// ...
],
For more details check docs
UPDATE:
If you're getting [UnexpectedValueException] Could not parse version constraint :5.4.0: Invalid version string ":5.4.0" error then you can insert this entry manually in composer.json. And after that then use composer update.
What you need now is just add "laravelcollective/html": "5.4.*", below the row with "laravel/framework":"5.4.*" as below:
"require": {
"php": ">=7.0.0",
"fideloper/proxy": "~3.3",
"laravel/framework": "5.4.*",
"laravelcollective/html": "5.4.*", // Add this entry and then run composer update
"laravel/tinker": "~1.0"
},
