🚀 Quick Start

Creating Fields

The package provides multiple ways to create fields:

Method 1: Using Field::make() (Recommended)

use Litepie\Form\Field;

// Simple field
$field = Field::make('text', 'username');

// With fluent API
$field = Field::make('select', 'theme')
    ->label('Select Theme')
    ->options(['dark' => 'Dark Mode', 'light' => 'Light Mode'])
    ->required();

// With options array
$field = Field::make('email', 'contact', [
    'label' => 'Email Address',
    'required' => true,
    'placeholder' => 'you@example.com'
]);

Method 2: Using Form Builder add() method

use Litepie\Form\Facades\Form;

$form = Form::create()
    ->add('name', 'text', ['label' => 'Name', 'required' => true])
    ->add('email', 'email', ['label' => 'Email']);

Method 3: Using Specific Field Classes

use Litepie\Form\Fields\TextField;
use Litepie\Form\Fields\SelectField;

$textField = new TextField('username');
$selectField = new SelectField('country');

Basic Contact Form

use Litepie\Form\Facades\Form;
use Litepie\Form\Field;

$contactForm = Form::create()
    ->action('/contact')
    ->method('POST')
    ->add(Field::make('text', 'name')
        ->label('Full Name')
        ->required()
        ->placeholder('Enter your full name')
        ->rules('required|string|max:255')
    )
    ->add(Field::make('email', 'email')
        ->label('Email Address')
        ->required()
        ->rules('required|email')
    )
    ->add(Field::make('textarea', 'message')
        ->label('Message')
        ->required()
        ->setAttribute('rows', 5)
        ->rules('required|string|min:10')
    )
    ->add(Field::make('submit', 'submit')
        ->value('Send Message')
        ->addClass('btn btn-primary')
    );

// In your Blade template
{!! $contactForm->render() !!}

Registration Form with File Upload

$registrationForm = Form::create()
    ->action('/register')
    ->method('POST')
    ->files(true)
    ->add(Field::make('image', 'avatar')
        ->label('Profile Picture')
        ->setAttribute('accept', 'image/*')
        ->setAttribute('maxSize', 5) // 5MB
        ->setAttribute('crop', true)
        ->setAttribute('aspectRatio', '1:1')
    )
    ->add(Field::make('text', 'first_name')
        ->label('First Name')
        ->required()
    )
    ->add(Field::make('text', 'last_name')
        ->label('Last Name')
        ->required()
    ])
    ->add('email', 'email', [
        'label' => 'Email',
        'required' => true,
        'validation' => 'required|email|unique:users'
    ])
    ->add('password', 'password', [
        'label' => 'Password',
        'required' => true,
        'validation' => 'required|min:8|confirmed'
    ])
    ->add('password_confirmation', 'password', [
        'label' => 'Confirm Password',
        'required' => true
    ])
    ->add('birth_date', 'date', [
        'label' => 'Date of Birth',
        'validation' => 'required|date|before:today'
    ])
    ->add('terms', 'checkbox', [
        'label' => 'I agree to the Terms of Service',
        'required' => true,
        'validation' => 'required|accepted'
    ]);

Helper Functions

// Quick form creation
$quickForm = form_quick([
    'name' => 'text',
    'email' => ['type' => 'email', 'required' => true],
    'message' => 'textarea'
], [
    'action' => '/contact',
    'method' => 'POST'
]);

// Standalone field
$nameField = form_field('name', 'text', [
    'label' => 'Full Name',
    'required' => true
]);

Field Visibility & Permissions

Control field visibility based on user permissions and roles:

use Litepie\Form\Facades\Form;

$userForm = Form::create()
    ->action('/users')
    ->forUser(auth()->user())  // Set user for all operations
    
    // Basic fields - visible to everyone
    ->add(Form::text('name')->label('Name'))
    ->add(Form::email('email')->label('Email'))
    
    // Only visible with permission
    ->add(
        Form::number('salary')
            ->label('Salary')
            ->can('view-salary')
    )
    
    // Only visible to specific roles
    ->add(
        Form::select('department')
            ->label('Department')
            ->options(['sales' => 'Sales', 'engineering' => 'Engineering'])
            ->roles(['manager', 'admin'])
    )
    
    // Custom visibility logic
    ->add(
        Form::text('api_key')
            ->label('API Key')
            ->visibleWhen(fn($user) => $user && $user->isPremium())
    );

// Render only visible fields
echo $userForm->render();

// For client-side (Vue, React, etc.) - only visible fields included
return response()->json([
    'form' => $userForm->toArray()
]);

See VISIBILITY.md for complete visibility control documentation.

Performance: Caching Form Output

Enable caching for forms that don't change frequently:

use Litepie\Form\Facades\Form;

// Enable caching with default TTL (1 hour)
$form = Form::create()
    ->forUser(auth()->user())
    ->cache()  // Enable caching
    ->add(Form::text('name'))
    ->add(Form::email('email'))
    ->add(Form::number('salary')->can('view-salary'));

// First render - generates and caches output
$html = $form->render();  // Slow

// Subsequent renders - returns cached output
$html = $form->render();  // Fast (from cache)

// Custom cache TTL (30 minutes)
$form->cache(1800);

// Cache is automatically scoped per user
$adminForm = $form->render($adminUser);    // Cached for admin
$managerForm = $form->render($managerUser); // Cached for manager

// Clear cache when needed
$form->clearCache();

// Disable caching
$form->withoutCache();

Use caching for:

Forms with many fields and complex visibility logic
API endpoints serving the same form to many users
Admin panels with heavy permission checks

Grid Layout & Column Width

Control field widths for responsive grid layouts (works with Bootstrap, Tailwind, or any frontend):

use Litepie\Form\Facades\Form;

// Default: all fields are 6 columns (half width)
$form = Form::create()
    ->add(Form::text('first_name'))  // 6 columns (default)
    ->add(Form::text('last_name'));  // 6 columns (default)

// Custom column widths
$form = Form::create()
    ->add(Form::text('first_name')->col(6))   // 6/12 columns
    ->add(Form::text('last_name')->col(6))    // 6/12 columns
    ->add(Form::email('email')->col(12))      // Full width
    ->add(Form::text('city')->col(4))         // 4/12 columns
    ->add(Form::text('state')->col(4))        // 4/12 columns
    ->add(Form::text('zip')->col(4));         // 4/12 columns

// Group fields in rows (Recommended)
$form = Form::create()
    // Row 1: Two half-width fields (auto row ID: 'row1')
    ->row([
        Form::text('first_name')->col(6),
        Form::text('last_name')->col(6)
    ])
    
    // Row 2: Three equal fields (auto row ID: 'row2')
    ->row([
        Form::text('city')->col(4),
        Form::text('state')->col(4),
        Form::text('zip')->col(4)
    ])
    
    // Row 3: Custom split (auto row ID: 'row3')
    ->row([
        Form::text('field1')->col(3),
        Form::text('field2')->col(4),
        Form::text('field3')->col(5)
    ])
    
    // Row with custom ID
    ->row([
        Form::textarea('notes')->col(12)
    ], 'notes-row');

// Alternative: Manual row assignment
$form = Form::create()
    ->add(Form::text('first_name')->col(6)->row('contact'))
    ->add(Form::text('last_name')->col(6)->row('contact'))
    ->add(Form::text('city')->col(4)->row('address'))
    ->add(Form::text('state')->col(4)->row('address'))
    ->add(Form::text('zip')->col(4)->row('address'));

// Change default width for all fields
$form = Form::create()
    ->defaultWidth(4)  // All fields 4 columns by default
    ->row([
        Form::text('field1'),      // 4 columns (uses default)
        Form::text('field2'),      // 4 columns (uses default)
        Form::text('field3')       // 4 columns (uses default)
    ])
    ->row([
        Form::text('notes')->col(12)  // Override: full width
    ]);

// Output includes width and row for client-side rendering
$data = $form->toArray();
// Each field has: 'width' => 6, 'totalColumns' => 12, 'row' => 'row1'

Frontend Implementation:

// Group fields by row
const rows = {};
Object.values(fields).forEach(field => {
  const rowId = field.row || 'default';
  if (!rows[rowId]) rows[rowId] = [];
  rows[rowId].push(field);
});

// Render each row with Bootstrap
Object.entries(rows).forEach(([rowId, rowFields]) => {
  const html = `
    <div class="row" data-row="${rowId}">
      ${rowFields.map(field => `
        <div class="col-md-${field.width}">
          ${renderField(field)}
        </div>
      `).join('')}
    </div>
  `;
});

// Render each row with Tailwind
Object.entries(rows).forEach(([rowId, rowFields]) => {
  const html = `
    <div class="grid grid-cols-12 gap-4" data-row="${rowId}">
      ${rowFields.map(field => `
        <div class="col-span-${field.width}">
          ${renderField(field)}
        </div>
      `).join('')}
    </div>
  `;
});

Hierarchical Form Organization (Groups, Sections, Rows)

Organize complex forms with a hierarchical structure: Form → Groups → Sections → Rows → Fields

use Litepie\Form\Facades\Form;

$form = Form::create()
    ->action('/users')
    
    // Group 1: Basic Information
    ->group('basic_info', 'Basic Information', 'Enter your basic details')
        
        // Section 1.1: Personal Details
        ->section('personal', 'Personal Details')
            ->row([
                Form::text('first_name')->col(6)->label('First Name')->required(),
                Form::text('last_name')->col(6)->label('Last Name')->required()
            ])
            ->row([
                Form::email('email')->col(6)->label('Email'),
                Form::tel('phone')->col(6)->label('Phone')
            ])
        ->endSection()
        
        // Section 1.2: Address
        ->section('address', 'Address Information')
            ->row([
                Form::text('street')->col(12)->label('Street Address')
            ])
            ->row([
                Form::text('city')->col(4)->label('City'),
                Form::text('state')->col(4)->label('State'),
                Form::text('zip')->col(4)->label('ZIP Code')
            ])
        ->endSection()
        
    ->endGroup()
    
    // Visual separator with label
    ->divider('Additional Details')
    
    // Group 2: Account Settings
    ->group('account_settings', 'Account Settings')
        
        ->section('security', 'Security')
            ->row([
                Form::password('password')->col(6)->label('Password'),
                Form::password('password_confirmation')->col(6)->label('Confirm Password')
            ])
        ->endSection()
        
        ->section('preferences', 'Preferences')
            ->row([
                Form::checkbox('newsletter')->label('Subscribe to newsletter'),
                Form::checkbox('notifications')->label('Enable notifications')
            ])
        ->endSection()
        
    ->endGroup()
    
    // Divider without label (just a line)
    ->divider()
    
    // Fields without group/section (top-level)
    ->row([
        Form::submit('submit')->value('Save Changes')->class('btn btn-primary')
    ]);

Key Features:

Groups: Top-level organization with titles and descriptions
Sections: Sub-groups within groups (can have multiple sections per group)
Rows: Layout containers for fields with column widths
Dividers: Visual separators with optional labels
Auto-assignment: Fields added after group() or section() automatically inherit the group/section
Flexible nesting: Mix grouped and ungrouped fields in the same form

Alternative Syntax (without fluent methods):

$form = Form::create()
    ->group('info', 'Information')
    
    // Add fields - they automatically get group='info'
    ->add(Form::text('name')->col(6)->section('personal'))
    ->add(Form::email('email')->col(6)->section('personal'))
    
    ->add(Form::text('company')->col(6)->section('business'))
    ->add(Form::text('title')->col(6)->section('business'))
    
    ->endGroup();

Output Structure (toArray/toJson):

{
  "fields": {
    "first_name": {
      "name": "first_name",
      "type": "text",
      "label": "First Name",
      "width": 6,
      "row": "row1",
      "group": "basic_info",
      "section": "personal"
    },
    "email": {
      "name": "email",
      "type": "email",
      "width": 6,
      "row": "row2",
      "group": "basic_info",
      "section": "personal"
    }
  }
}

Frontend Rendering:

// Group fields by hierarchy
const structure = {};

Object.values(fields).forEach(field => {
  const groupId = field.group || 'default';
  const sectionId = field.section || 'default';
  const rowId = field.row || 'default';
  
  if (!structure[groupId]) {
    structure[groupId] = { sections: {} };
  }
  if (!structure[groupId].sections[sectionId]) {
    structure[groupId].sections[sectionId] = { rows: {} };
  }
  if (!structure[groupId].sections[sectionId].rows[rowId]) {
    structure[groupId].sections[sectionId].rows[rowId] = [];
  }
  
  structure[groupId].sections[sectionId].rows[rowId].push(field);
});

// Render with Bootstrap
Object.entries(structure).forEach(([groupId, group]) => {
  html += `<div class="form-group-container" data-group="${groupId}">`;
  
  Object.entries(group.sections).forEach(([sectionId, section]) => {
    html += `<div class="form-section" data-section="${sectionId}">`;
    
    Object.entries(section.rows).forEach(([rowId, fields]) => {
      html += `<div class="row" data-row="${rowId}">`;
      fields.forEach(field => {
        html += `<div class="col-md-${field.width}">${renderField(field)}</div>`;
      });
      html += `</div>`;
    });
    
    html += `</div>`;
  });
  
  html += `</div>`;
});

Divider Types:

// Divider with label
->divider('Section Title')

// Plain divider (just a line)
->divider()

// Divider in specific group/section
->divider('Advanced Options', 'settings_group', 'advanced_section')

📦 Form Container - Managing Multiple Forms

The Form Container allows you to manage multiple forms within a single interface, with support for tabbed, accordion, or stacked layouts.

Basic Container Usage

use Litepie\Form\Facades\Form;

// Create a container with multiple forms
$container = Form::container('user-settings')
    ->name('User Settings')
    ->description('Manage your account settings')
    ->tabbed(true); // Use tabbed interface

// Add forms to the container
$profileForm = $container->createForm('profile', [
    'title' => 'Profile Information',
    'description' => 'Update your personal details'
]);

$profileForm
    ->add('first_name', 'text', ['label' => 'First Name', 'required' => true])
    ->add('last_name', 'text', ['label' => 'Last Name', 'required' => true])
    ->add('email', 'email', ['label' => 'Email', 'required' => true]);

$securityForm = $container->createForm('security', [
    'title' => 'Security Settings',
    'description' => 'Manage your password and security options'
]);

$securityForm
    ->add('current_password', 'password', ['label' => 'Current Password'])
    ->add('new_password', 'password', ['label' => 'New Password'])
    ->add('confirm_password', 'password', ['label' => 'Confirm Password']);

// Render the container
{!! $container->render() !!}

Quick Container Creation

// Create multiple forms at once
$container = Form::quickContainer([
    'contact' => [
        'fields' => [
            'name' => 'text',
            'email' => ['type' => 'email', 'required' => true],
            'message' => ['type' => 'textarea', 'required' => true]
        ],
        'options' => ['action' => '/contact', 'method' => 'POST'],
        'containerOptions' => [
            'title' => 'Contact Information',
            'description' => 'Get in touch with us'
        ]
    ],
    'feedback' => [
        'fields' => [
            'rating' => ['type' => 'range', 'min' => 1, 'max' => 5],
            'suggestion' => 'textarea'
        ],
        'containerOptions' => [
            'title' => 'Feedback',
            'description' => 'Help us improve'
        ]
    ]
], [
    'name' => 'Contact & Feedback',
    'accordion' => true // Use accordion interface
]);

Container Display Modes

// Tabbed interface
$container->tabbed(true)->activeForm('step1');

// Accordion interface
$container->accordion(true);

// Stacked interface (default)
// Forms displayed one after another

Container Validation Modes

// Individual validation (default) - each form validated separately
$container->validationMode('individual');

// Combined validation - all forms must pass
$container->validationMode('combined');

// Sequential validation - stops at first failure
$container->validationMode('sequential');

Extended Container Classes

class RegistrationContainer extends \Litepie\Form\FormContainer
{
    public function __construct($app)
    {
        parent::__construct($app, 'registration');
        $this->setupRegistrationForms();
    }

    protected function setupRegistrationForms(): void
    {
        $this->name('User Registration')
             ->tabbed(true)
             ->validationMode('sequential');

        // Step 1: Personal Information
        $personal = $this->createForm('personal', [
            'title' => 'Personal Information',
            'icon' => 'user'
        ]);

        $personal
            ->add('first_name', 'text', ['required' => true])
            ->add('last_name', 'text', ['required' => true])
            ->add('email', 'email', ['required' => true]);

        // Step 2: Account Setup
        $account = $this->createForm('account', [
            'title' => 'Account Setup',
            'icon' => 'key'
        ]);

        $account
            ->add('password', 'password', ['required' => true])
            ->add('password_confirmation', 'password', ['required' => true]);
    }

    public function getProgress(): int
    {
        $totalSteps = $this->forms->count();
        $currentStep = array_search($this->getActiveForm(), $this->getFormKeys());
        return (int)(($currentStep + 1) / $totalSteps * 100);
    }
}

// Usage
$registrationContainer = new RegistrationContainer(app());
echo $registrationContainer->render();

🌐 Laravel Integration

Controller Example

class ContactController extends Controller
{
    public function create()
    {
        $form = Form::create()
            ->action(route('contact.store'))
            ->method('POST')
            ->add('name', 'text', ['required' => true])
            ->add('email', 'email', ['required' => true])
            ->add('submit', 'submit', ['value' => 'Send']);

        return view('contact.create', compact('form'));
    }

    public function store(Request $request)
    {
        // Form validation is automatic
        $validated = $request->validate([
            'name' => 'required|string|max:255',
            'email' => 'required|email'
        ]);

        // Process the form...
        
        return redirect()->back()->with('success', 'Message sent!');
    }
}

Blade Template Integration

@extends('layouts.app')

@section('content')
<div class="container">
    <h1>Contact Us</h1>
    
    @if(session('success'))
        <div class="alert alert-success">
            {{ session('success') }}
        </div>
    @endif

    {!! $form->render() !!}
</div>
@endsection

@push('styles')
    {!! form_include_assets(true, false) !!}
@endpush

@push('scripts')
    {!! form_include_assets(false, true) !!}
@endpush

🚀 Client-Side Framework Integration

Convert Forms to Arrays/JSON for Vue.js, React, Angular

// Convert existing form to array
$form = Form::create()
    ->add('name', 'text', ['required' => true])
    ->add('email', 'email', ['required' => true]);

$formArray = $form->toArray();
$formJson = $form->toJson();

// Or use helper functions
$formArray = form_array([
    'name' => ['type' => 'text', 'label' => 'Name', 'required' => true],
    'email' => ['type' => 'email', 'label' => 'Email', 'required' => true]
], [
    'action' => '/api/contact',
    'method' => 'POST'
]);

$formJson = form_json($fields, $options);

API Endpoint for Client-Side

// Return form schema as JSON for Vue/React/Angular
Route::get('/api/forms/contact', function() {
    return form_array([
        'name' => ['type' => 'text', 'label' => 'Name', 'required' => true],
        'email' => ['type' => 'email', 'label' => 'Email', 'required' => true],
        'message' => ['type' => 'textarea', 'label' => 'Message', 'required' => true]
    ], [
        'action' => '/api/contact',
        'method' => 'POST'
    ]);
});

Vue.js Example

<template>
  <form @submit.prevent="submitForm">
    <div v-for="(field, name) in formFields" :key="name">
      <label>{{ field.label }}</label>
      <input 
        v-if="field.type === 'text'"
        v-model="formData[name]"
        :type="field.type"
        :required="field.required"
      />
      <textarea 
        v-if="field.type === 'textarea'"
        v-model="formData[name]"
        :required="field.required"
      ></textarea>
    </div>
    <button type="submit">Submit</button>
  </form>
</template>

<script>
export default {
  data() {
    return {
      formFields: {},
      formData: {}
    }
  },
  async mounted() {
    const response = await fetch('/api/forms/contact')
    const schema = await response.json()
    this.formFields = schema.fields
    
    // Initialize form data
    Object.keys(this.formFields).forEach(field => {
      this.$set(this.formData, field, '')
    })
  }
}
</script>

⚡ Performance & Caching

Caching Support

Form containers support comprehensive caching to improve performance:

// Enable caching with custom TTL
$container = Form::container('user-settings')
    ->enableCache(3600) // 1 hour
    ->cacheTags(['user_forms', 'settings']);

// Configure cache settings
$container->cache([
    'enabled' => true,
    'ttl' => 1800, // 30 minutes
    'driver' => 'redis',
    'tags' => ['forms', 'containers'],
]);

// Cache is automatically applied to:
// - render() - Caches full HTML output
// - renderSingleForm() - Caches individual form HTML
// - toArray() - Caches array representation
// - getVisibleForms() - Caches filtered collections

// Manual cache management
$container->clearCache(); // Clear all cache for this container
$container->disableCache(); // Temporarily disable caching

Cache Configuration

Add to your config/form.php:

'cache' => [
    'enabled' => env('FORM_CACHE_ENABLED', true),
    'ttl' => env('FORM_CACHE_TTL', 3600),
    'driver' => env('FORM_CACHE_DRIVER', 'redis'),
    'prefix' => 'form_cache',
    'tags' => ['forms', 'containers'],
    'auto_clear_on_update' => true,
],

Cache Benefits

50-90% faster rendering for complex forms
Reduced server load with cached HTML output
Automatic invalidation when forms are modified
Tagged cache for efficient bulk clearing
Multiple drivers (file, redis, memcached)

For detailed caching documentation, see doc/caching.md.
