Form Builder

Splade has an advanced Form Builder that enables you to build forms from your controllers instead of in your templates. Check out the Form Components section to learn more about Splade's form capabilities.

Basic example

You may use the SpladeForm class to configure the form.

<?php
 
namespace App\Http\Controllers;
 
use ProtoneMedia\Splade\FormBuilder\Input;
use ProtoneMedia\Splade\FormBuilder\Password;
use ProtoneMedia\Splade\FormBuilder\Submit;
use ProtoneMedia\Splade\SpladeForm;
 
class UsersController
{
    public function create()
    {
        $form = SpladeForm::make()
            ->action(route('users.store'))
            ->fields([
                Input::make('name')->label('User Name'),
                Password::make('password')->label('Password'),
                Submit::make()->label('Create'),
            ]);
 
        return view('users.create', [
            'form' => $form,
        ]);
    }
}

Then in the Blade template, you must pass the form to the for attribute. That's it!

<x-splade-form :for="$form" />

Besides the action() and fields() methods, there are additional methods to configure the form:

SpladeForm::make()
    ->id('create-user-form')
    ->class('space-y-4')
    ->method('POST');

To show a confirmation dialog before Splade submits the form, simply use the confirm() method. You may customize the confirmation dialog as well.

SpladeForm::make()->confirm();
 
SpladeForm::make()->confirm(
    confirm: 'Delete user',
    text: 'Are you sure you want to delete this user?',
    confirmButton: 'Delete',
    cancelButton: 'Cancel',
    danger: true,
    requirePassword: true,
);

Instead of requiring a password using the confirm() method, you may also use the dedicated requirePassword() method:

SpladeForm::make()->requirePassword();
 
SpladeForm::make()->requirePassword(
    requirePasswordOnce: false,
    heading: 'Please enter your password',
    text: 'Please confirm your password before continuing',
    confirmButton: 'Confirm',
    cancelButton: 'Cancel',
    danger: false
);

Passing default data

You may use the fill method to provide a set of default data to the form:

$project = Project::firstOrFail();
 
SpladeForm::make()
    ->fields([...])
    ->fill($project);

Note that the Eloquent attributes are passed to the frontend, so be careful with sensitive attributes. By default, it only passes the attributes to the frontend that you use in the fields. You may use a Transformer to help you safely pass data to the frontend. Also, check out the Model Binding Attributes section.

Form Class

Instead of using an inline SpladeForm in the controller, you may also use a dedicated class. There's an Artisan command to generate a Form class:

php artisan make:form CreateUserForm

You'll find the new Form class in the app/Forms folder. You may use this class in the controller instead of the inline instance:

use App\Forms\CreateUserForm;
 
return view('users.create', [
    'form' => $form,      
    'form' => CreateUserForm::class,      
]);

The generated CreateUserForm will have a configure() and fields() method:

<?php
 
namespace App\Forms;
 
use ProtoneMedia\Splade\AbstractForm;
use ProtoneMedia\Splade\FormBuilder\Input;
use ProtoneMedia\Splade\FormBuilder\Password;
use ProtoneMedia\Splade\FormBuilder\Submit;
use ProtoneMedia\Splade\SpladeForm;
 
class CreateUserForm extends AbstractForm
{
    public function configure(SpladeForm $form)
    {
        $form->action(route('users.store'));
    }
 
    public function fields(): array
    {
        return [
            Input::make('name')->label('User Name'),
            Password::make('password')->label('Password'),
            Submit::make()->label('Create'),
        ];
    }
}

Validation

You may pass validation rules to the fields using the rules() method:

Input::make('name')->rules('required', 'max:255');
 
// or:
 
Input::make('name')->rules(['required', 'max:255']);
 
// or:
 
Input::make('name')->rules('required|max:255');

There's a required() helper method that adds the required rule to the field:

Input::make('name')->required();

You may gather all rules using the static rules() method on the form class, which you can use in the controller to validate an incoming request:

public function store(Request $request)
{
    $data = $request->validate(CreateUserForm::rules());
}

Alternatively, you may call the validate() method on the form instance. This works great with a type-hinted form variable:

public function store(Request $request, CreateUserForm $form)
{
    $data = $form->validate($request);
}

Asterisk on required fields

Splade can automatically add an asterisk to required fields. You may enable this feature by setting the blade.asterisk_on_required_form_elements key in the splade.php configuration file to true.

Using Form Requests

Instead of validating the request in the controller, you may also use Laravel's Form Requests feature. To may use the form's validation rules in the Form Request, and to make it even more seamless, there's an Artisan command to generate a Form Request class:

php artisan make:form-request CreateUserFormRequest --form=CreateUserForm

Alternatively, you can generate both at once using -r or --request option on the make:form command:

php artisan make:form CreateUserForm --request

This will generate a Form Request with the rules() method already implemented:

<?php
 
namespace App\Http\Requests;
 
use App\Forms\CreateUserForm;
use Illuminate\Foundation\Http\FormRequest;
 
class CreateUserFormRequest extends FormRequest
{
    public function rules()
    {
        return CreateUserForm::rules();
    }
}

Extending Form classes

Instead of providing the class name, you may also use an instance of the form using the make() method. This allows you to add additional fields to the form:

return view('users.create', [
    'form' => CreateUserForm::make()->fields([
        Text::make('additional_field')->label('This is an additional field'),
    ]),
]);

Extending Form Fields

All Form Fields are macroable, allowing you to easily add new methods:

use ProtoneMedia\Splade\FormBuilder\Input;
 
Input::macro('autocomplete', function ($value) {
    return $this->attributes(['autocomplete' => $value]);
});
 
Input::make('password')->autocomplete('current-password');

Frontend behavior

In addition to configuring the form, fields, rules, and filled data, you may also configure its frontend behavior:

Prevent navigation on submit

You may instruct Splade to stay on the same page after a successful request:

SpladeForm::make()->stay();

In additional, you may specify to reset or restore the form on success:

SpladeForm::make()->stay(actionOnSuccess: 'reset');
SpladeForm::make()->stay(actionOnSuccess: 'restore');

Preserve Scroll

When you stay on the same page after a succesful request, you may prevent the page from scrolling to the top:

SpladeForm::make()->stay()->preserveScroll();

Submit on change

You may watch form values, and automatically submit the form on changes.

SpladeForm::make()->submitOnChange(watchFields: 'theme');
 
// or:
 
SpladeForm::make()->submitOnChange(watchFields: ['theme', 'scale']);

You may omit the fields to watch all fields, as well as customize the debounce value and performing the request in the background:

SpladeForm::make()->submitOnChange();
SpladeForm::make()->submitOnChange(background: true);
SpladeForm::make()->submitOnChange(debounce: 1000);

Warning The submitOnChange() method will not show a confirmation or password dialog.
