What is Laravel Form Builder?
The package that is available in Laravel as a form builder is actually presented by Kristijan Husak and it also incorporates an API inside it that is like that of Symfony’s form builder. Symfony’s form builder has been an inspiration for the creation of Laravel form builder. This Form Builder can easily run as a standalone installation as it is self-contained with all the necessary requirements to run as a complete package. You don’t need to have builder codes to run the Laravel form builder as it operates easily without the need for coding. There are readily available templates that can be incorporated into the form that the user wishes to create for the application or the webpage in the Laravel PHP Framework. Similarly, to note is the fact that Laravel does not entertain applications that are created in other PHP frameworks and brought into Laravel for editing. The essential need is that the application needs to be created inside the framework of Laravel.

<div class="radio">
<label>
<input type="radio" name="role" value="{{ $role->id }}"
{{ old('role', $user->role_id) == $role->id ? 'checked' : '' }}
{{ is_null($user->role_id) && $role->id == 1 ? 'checked' : '' }}
>
{{ $role->name }}
</label>
</div>
@endforeachForm Builder:
@foreach($roles as $role)
<div class="radio">
<label>
{{ Form::radio('role', $role->id, 1) }}
{{ $role->name }}
</label>
</div>

How does Laravel Form Builder Work?
You can get started by creating the form builder the way you want it for your project. You can generate the type of forms that you would need to keep inside your project and start working on it. Various types of forms can be incorporated inside the Laravel design framework while wanting to formulate forms for the editing purpose.
This image is of a template for a form builder that can be used to create a typical form type according to the need. You can generate the code as per the need and it will help to create the form as you would insert the code.
Once the project is downloaded from GitHub or any other source for Laravel, you can clone it and install the dependencies as they will be required for the running. Install the package that you have with you with the help of the composer that is available in Laravel. After that, open the link for the form builder that you will be able to see on a browser page and start building form by putting the necessary codes as needed. Later on, the testing of the project can be done to confirm if the form is built properly without any errors in it.
Example
A simple form can be generated with the help of this code as follows:
<?php
namespace App\Forms;
use Kris\LaravelFormBuilder\Form;
classSongForm extends Form
{
public function buildForm()
{
$this
->add('name', 'text', [
'rules' => 'required|min:5'
])
->add('lyrics', 'textarea', [
'rules' => 'max:5000'
])
->add('publish', 'checkbox');
}
}Form objects can be then created inside the controller.
$form = $formBuilder->create(\App\Forms\SongForm::class, [
'method' => 'POST',
'url' => route('song.store')
]);The following is then used for rendering the form object:
{!! form($form) !!}Validation process:
$form = $formBuilder->create(\App\Forms\SongForm::class);
if (!$form->isValid()) {
return redirect()->back()->withErrors($form->getErrors())->withInput();
}
// ...Available artisan command for generating forms and fields:
php artisan make:form Forms/SongForm \
--fields="name:text, lyrics:textarea, publish:checkbox"We shall look at the code created for the following form Image:
