Laravel - Forms

In Laravel, working with forms is made easy with the help of the Blade templating engine and Laravel Collective's HTML and Form Builders. Here's a guide on working with forms in Laravel:

1. Creating Forms:

Forms can be created using the form method provided by Laravel Collective. Laravel Collective provides a set of HTML and Form helper methods that simplify the process of creating and working with HTML forms.

First, you need to install Laravel Collective:

composer require laravelcollective/html
 

After installation, you should add the service provider and facade in the config/app.php file:

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

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

2. Creating a Form:

In your Blade view, you can use the Form facade to create forms.

{!! Form::open(['url' => '/submit', 'method' => 'post']) !!}
    // Form fields and controls go here
{!! Form::close() !!}
 

3. Form Fields:

Laravel Collective provides methods for various form fields:

{!! Form::text('name', null, ['class' => 'form-control']) !!}
{!! Form::password('password', ['class' => 'form-control']) !!}
{!! Form::email('email', null, ['class' => 'form-control']) !!}
{!! Form::select('role', ['admin' => 'Admin', 'user' => 'User'], null, ['class' => 'form-control']) !!}
 

4. CSRF Protection:

Laravel automatically adds CSRF protection to your forms. Use the @csrf directive to include the CSRF token.

{!! Form::open(['url' => '/submit', 'method' => 'post']) !!}
    @csrf
    // Form fields and controls go here
{!! Form::close() !!}
 

5. Form Validation:

You can validate form data using Laravel's built-in validation features. The validate method can be called in your controller to validate the incoming request.

 public function store(Request $request)
{
    $request->validate([
        'name' => 'required|string|max:255',
        'email' => 'required|email|unique:users',
        'password' => 'required|min:8',
    ]);

    // Process the form data
}

6. Old Input:

After a form submission with validation errors, you can repopulate the form fields with old input using the old method.

{!! Form::text('name', old('name'), ['class' => 'form-control']) !!}

7. Form Actions:

Set the action attribute of the form to the URL where the form data should be submitted.

{!! Form::open(['url' => '/submit', 'method' => 'post']) !!}
    // Form fields and controls go here
    {!! Form::submit('Submit', ['class' => 'btn btn-primary']) !!}
{!! Form::close() !!}
