Laravel Livewire form component with declarative Bootstrap 5 fields and buttons.

Requirements

• Bootstrap 5

Installation

composer require bastinald/laravel-livewire-forms

Usage

Make a new form:

php artisan make:form users.create-user-form

Declare fields:

public function fields()
{
    return [
        Input::make('name', 'Name'),
        Input::make('email', 'Email')->type('email'),
        Input::make('password', 'Password')->type('password'),
    ];
}

Declare buttons:

public function buttons()
{
    return [
        Button::make('Create User')->click('createUser'),
        Button::make('Cancel', 'secondary')->url('/'),
    ];
}

Declare rules:

public function rules()
{
    return [
        'name' => ['required', 'string', 'max:255'],
        'email' => ['required', 'string', 'email', 'max:255', 'unique:users'],
        'password' => ['required', 'string', 'min:8'],
    ];
}

Declare an action (notice the use of ->click('createUser') in the button example above:

public function createUser()
{
    $this->validate();

    User::create([
        'name' => $this->data('name'),
        'email' => $this->data('email'),
        'password' => Hash::make($this->data('password')),
    ]);

    return redirect('/');
}

Full Page Forms

Create a full page form by specifying a title, layout and route to use:

class Login extends FormComponent
{
    public $title = 'Login';
    public $layout = 'layouts.card';

    public function route()
    {
        return Route::get('/login', static::class)
            ->name('login')
            ->middleware('guest');
    }

The route method is made available by using my laravel-livewire-routes package.

Setting Initial Data

You can set the initial form data / defaults via the data array property in your component mount method:

class UpdateUserForm extends FormComponent
{
    public $title = 'Update User';
    
    public function route()
    {
        return Route::get('/users/update/{user}', static::class)
            ->name('users.update')
            ->middleware('auth');
    }
    
    public function mount(User $user)
    {
        $this->data = $user->toArray();
    }

Accessing Data

Use the data method in the component to access current form data (you can use dot notation for array values):

public function createUser()
{
    User::create([
        'name' => $this->data('name'),
        'email' => $this->data('email'),
        'likes_turtles' => $this->data('answers.likes_turtles'),
    ]);
}

Data Binding

Most fields allow you to change the way livewire binds data via helper methods that are chained to fields e.g.:

Input::make('name', 'Name'), // defaults to defer
Input::make('name', 'Name')->instant(), // bind on keyup 
Input::make('name', 'Name')->defer(), // bind on action 
Input::make('name', 'Name')->lazy(), // bind on change
Input::make('name', 'Name')->debounce(500), // bind after 500ms delay 

Sizing

Many fields also allow you to specify a size for the input e.g.:

Input::make('name', 'Name'), // defaults to normal sizing
Input::make('name', 'Name')->small(), // small sizing
Input::make('name', 'Name')->large(), // large sizing

Disabling

Some fields allow you to disable or set them to readonly, and even plaintext for inputs:

Input::make('name', 'Name')->disabled(),
Input::make('name', 'Name')->readonly(),
Input::make('name', 'Name')->plaintext(),

Helper Text

Specify helper text for a field by using the help method:

Input::make('name', 'Name')->help('Please tell us your name!'),

Available Fields

Alert ($message, $style = 'success')

An alert box.

Alert::make('It worked!'),
Alert::make('Something bad happened.', 'danger'),

The $style parameter accepts a bootstrap alert style e.g. success, danger, primary, etc. Use the dismissible method to make the alert dismissible.

Available methods: dismissible

Arrayable ($name, $label = null)
