README

Driver-based form flow orchestration system with DirXML-style mapping for Laravel applications.

Features

Driver-Based Architecture: Define multi-step form flows using YAML configuration files
DirXML-Style Mapping: Transform and map data between steps using flexible mapping rules
Handler Plugin System: Extend functionality with custom form handlers
Built-in Handlers: FormHandler, SplashHandler, and MissingHandler included
Vue Components: Pre-built Inertia.js Vue components for rapid development
Configurable: Customize route prefixes, middleware, and behavior
Self-Contained: Automatic CSRF handling, route registration, and asset publishing

Requirements

PHP ^8.2
Laravel ^11.0 || ^12.0 || ^13.0
Inertia.js ^2.0 || ^3.0

Installation

Install via Composer:

composer require 3neti/form-flow:^1.8

Publish Assets

Publish the configuration file:

php artisan vendor:publish --tag=form-flow-config

Publish driver examples:

php artisan vendor:publish --tag=form-flow-drivers

Publish Vue components:

php artisan vendor:publish --tag=form-flow-views

Or publish everything at once:

php artisan vendor:publish --tag=form-flow-core

Configuration

The package configuration is located at config/form-flow.php:

return [
    'route_prefix' => env('FORM_FLOW_ROUTE_PREFIX', 'form-flow'),
    'middleware' => ['web'],
    'driver_directory' => config_path('form-flow-drivers'),
    'session_prefix' => 'form_flow',
    'handlers' => [
        // Plugin handlers register themselves via service providers
    ],
];

Usage

Creating a Form Flow

Define a flow driver in config/form-flow-drivers/my-flow.yaml:

name: my-flow
title: My Form Flow
steps:
  - handler: splash
    config:
      title: Welcome
      message: Let's get started
      
  - handler: form
    config:
      title: User Information
      fields:
        - name: full_name
          type: text
          label: Full Name
          validation: required|string|max:255

Starting a Flow

use Illuminate\Support\Facades\Http;

$response = Http::post('/form-flow/start', [
    'reference_id' => 'unique-transaction-id',
    'steps' => [
        ['handler' => 'splash', 'config' => [...]],
        ['handler' => 'form', 'config' => [...]],
    ],
    'callbacks' => [
        'on_complete' => 'https://your-app.com/api/flow-complete',
        'on_cancel' => 'https://your-app.com/api/flow-cancelled',
    ],
]);

$flowUrl = $response->json('flow_url');

Available Routes

The package automatically registers these routes:

POST /form-flow/start - Start a new flow
GET /form-flow/{flow_id} - Show current step
POST /form-flow/{flow_id}/step/{step} - Update step data
POST /form-flow/{flow_id}/complete - Complete flow
POST /form-flow/{flow_id}/cancel - Cancel flow
DELETE /form-flow/{flow_id} - Destroy flow state

Plugin Development

Create custom handlers by implementing FormHandlerInterface:

use LBHurtado\FormFlowManager\Contracts\FormHandlerInterface;

class MyCustomHandler implements FormHandlerInterface
{
    public function getName(): string
    {
        return 'my-custom';
    }
    
    public function handle(Request $request, FormFlowStepData $step, array $context = []): array
    {
        // Process step data
        return ['processed' => true];
    }
    
    public function render(FormFlowStepData $step, array $context = [])
    {
        return inertia('MyCustomView', [...]);
    }
    
    // ... other methods
}

public function boot(): void
{
    $handlers = config('form-flow.handlers', []);
    $handlers['my-custom'] = MyCustomHandler::class;
    config(['form-flow.handlers' => $handlers]);
}

Vue Components

The package includes ready-to-use Vue components:

GenericForm.vue - Generic form renderer
Splash.vue - Splash screen handler
Complete.vue - Flow completion page
MissingHandler.vue - Fallback for missing handlers

Testing

The current release matrix covers PHP 8.3 and 8.4 on Laravel 12 and 13. Laravel 11 remains supported by the package constraints.
