Add comprehensive developer documentation for choosing between lib/ (legacy) and src/V3 (modern) implementations of Horde_Form. Content includes: - Quick decision guide (when to use each) - Architecture comparison (lib/ vs V3) - Breaking changes list (validation signature, getInfo(), etc.) - Migration path (per-form, all-or-nothing) - Gotchas in lib/ with PHP 8.4+ (singleton, references, no type hints) - API compatibility matrix - Real-world examples (simple forms, custom types) - FAQ Key guidance: - Use lib/ for existing/production apps, forms needing Actions/Renderer - Use V3 for new apps when BaseForm is ready (currently incomplete) - Cannot mix lib/ and V3 in same form (incompatible interfaces) - lib/ maintained through H6, will be deprecated in H7+ once V3 stable Closes #17
Implement complete BaseForm class as modern replacement for lib/Horde_Form following V3 design principles from issue #19. ## Features **Multi-type input support:** - Accepts Horde_Variables (legacy compatibility) - Accepts PSR-7 ServerRequest (modern apps) - Accepts plain arrays (testing, simple apps) - Normalizes all inputs to array internally **Core form methods:** - addVariable() - Add form fields with factory pattern - insertVariableBefore() - Insert fields at specific positions - addHidden() - Add hidden fields - removeVariable() - Remove fields dynamically - getVariables() - Retrieve fields (flat or by section) - validate() - Validate all fields with error collection - getInfo() - Extract validated data - Section support for organizing fields **Modern PHP patterns:** - Named parameters throughout - Strict typing (PHP 8.2+) - Match expressions for type normalization - Clean factory method for Variable creation - No singleton pattern - Minimal reference passing **Form interface:** - Define minimal contract (6 core methods) - Allow implementation flexibility - Documented for V3 usage **Bug fixes:** - Fix BaseVariable::$_action typed property initialization - Fix BaseVariable::$form type (accept Form interface, not Horde_Form) - Add Horde class stub for testing ## Architecture V3 acts as bridge between lib/ (legacy) and V4 (pure PSR-7): - Constructor accepts multiple types (backward compatible) - Internal storage as array (modern, typed) - Variables wrapped in Horde_Variables for BaseVariable compatibility - Clear migration path: lib/ → V3 → V4 ## Testing Added integration test demonstrating: - All three input types (Horde_Variables, array, PSR-7) - Variable management (add, remove, get) - Validation with error handling - Data extraction (getInfo) - Sections and hidden fields - All tests pass ✓ Related: #19
Port action system from lib/ to V3 with modern PHP patterns.
## Actions System
**Base infrastructure:**
- Action interface - Contract for all actions
- BaseAction - Abstract base with common functionality
- Factory pattern for creating actions (no singleton)
**Actions implemented:**
1. ConditionalenableAction - Enable/disable fields conditionally
2. SumfieldsAction - Calculate sum of numeric fields
3. SubmitAction - Auto-submit form on field change
4. ReloadAction - Reload form with current values
5. (ConditionalSetValue, updatefield, setcursorpos - TODO Phase 2)
## V3 Improvements
**Modern patterns:**
- Strict typing (PHP 8.2+)
- Named parameters throughout
- No singleton pattern (use new or factory())
- Clean factory method (no PEAR errors)
- Interface-based design
**API changes:**
- BaseAction::factory() - Modern factory (throws exception)
- Removed singleton() method (antipattern)
- Removed PHP 4 constructor
- Action interface typed for Form, not Horde_Form
## BaseVariable Updates
**Breaking changes:**
- \$_action property now typed as Action (was Horde_Form_Action)
- Removed transitional lib/ imports (Horde_Form_Action, Horde_Form)
- Now uses V3 Action interface exclusively
**Migration:**
```php
// Old (lib/)
\$v->setAction(Horde_Form_Action::factory('submit'));
// New (V3)
\$v->setAction(BaseAction::factory('Submit'));
```
## Technical Details
Actions generate JavaScript for client-side form behavior:
- ConditionalEnable: checkEnabled() function
- SumFields: sumFields() function
- Submit: form.submit()
- Reload: Clear formname, submit
All actions extend BaseAction and implement Action interface.
## Testing
Actions integrated with BaseForm (tested manually).
Comprehensive unit tests TODO (Phase 2).

Create complete interface hierarchy for V3 renderer system. ## Renderer Architecture **Strategy pattern + separated concerns:** - Renderer (main interface) - Coordinates rendering - ControlRenderer - Renders form controls (input, select, etc.) - LayoutStrategy - Determines form structure (table, div, list) - ErrorRenderer - Handles error display - AssetManager - Manages JS/CSS assets ## Key Interfaces **1. Renderer** - Main interface - render() - Complete form - renderOpen/Close() - Form tags - renderHeader() - Title, description - renderVariable() - Single field - renderSection() - Group of fields - renderButtons() - Submit/reset - renderErrors() - Validation errors - renderHidden() - Hidden fields **2. ControlRenderer** - Form controls - renderControl() - Any variable type - renderLabel() - Field label - renderHelp() - Help text - getFieldId() - Unique ID generation **3. LayoutStrategy** - Form structure - wrapField() - Label + control + help + error - wrapSection() - Section container - wrapForm() - Complete form structure **4. ErrorRenderer** - Error display - renderFieldError() - Single field error - renderFormErrors() - Error summary **5. AssetManager** - Asset management - addScript() - JavaScript files - addStylesheet() - CSS files - addInlineScript/Style() - Inline code - render() - Output <script>/<link> tags ## Design Principles **Separation of concerns:** - Each interface has single responsibility - Clean dependencies (no circular refs) - Pluggable strategies (swap layout, errors, etc.) **Multiple rendering formats:** - HTML+JS (interactive) - JSON (APIs) - HTML-Print (printer-friendly) - HTML-Inactive (display-only) **Feature parity with lib/:** - All configuration options - All rendering modes - Section tabs - Help/required markers - Striped rows - Custom layouts ## Implementation Plan Phase 1: Core (done) ✓ Phase 2: HTML renderer (3-4h) Phase 3: All variable types (2-3h) Phase 4: Alternative renderers (2-3h) Phase 5: Polish (1-2h) Total: 8-12 hours Design doc: ~/horde-development/horde-form-v3-renderer-design.md Related: #19
Complete implementation of V3 HTML renderer with all components.
## Core Components
**BaseRenderer** (abstract base)
- Template method pattern
- Common rendering logic
- Configurable (showHeader, markers, striped rows)
- Component injection (control, layout, error, asset renderers)
**HtmlRenderer** (concrete implementation)
- HTML+JS output
- Active/inactive/print modes
- Form open/close tags
- Header, errors, buttons rendering
## Rendering Components
**HtmlControlRenderer** - Form controls
- Handles 15+ variable types (text, enum, boolean, email, number, etc.)
- Label + control + help rendering
- Readonly/disabled support
- Field ID generation
- HTML5 input types (email, number, date, time, etc.)
**TableLayout** - lib/ compatible layout
- 2-column table structure
- Label column (15% width)
- Control column
- Section support
- Striped rows
**InlineErrorRenderer** - Validation errors
- Field-level errors (inline)
- Form-level error summary
- HTML-safe escaping
**HtmlAssetManager** - JS/CSS management
- Script/stylesheet tracking
- Inline code support
- Renders <script>/<link> tags
## Features
**Multi-type support:**
- text, email, number, int
- enum (select), multienum (multi-select)
- boolean (checkbox), radio
- longtext (textarea)
- password
- file upload
- date, time, datetime
**Form structure:**
- Sections with titles/descriptions
- Hidden fields
- Required markers
- Help text
- Error display
- Striped rows (optional)
**Configuration:**
- showHeader (default: true)
- requiredMarker (default: *)
- helpMarker (default: ?)
- encodeTitle (default: true)
- stripedRows (default: false)
## Testing
Created test_renderer.php - all tests pass ✓
- Form creation with fields
- HTML rendering (1244 bytes)
- Error rendering works
- All components integrated
## Architecture
Strategy pattern:
- Renderer (main orchestrator)
- ControlRenderer (pluggable controls)
- LayoutStrategy (pluggable layout)
- ErrorRenderer (pluggable errors)
- AssetManager (pluggable assets)
Clean separation:
- BaseForm = logic
- Renderer = presentation
- No mixing of concerns
## Usage
```php
$form = new BaseForm($_POST, 'Contact Form');
$form->addVariable('Name', 'name', 'text', true);
$form->addVariable('Email', 'email', 'email', true);
$renderer = new HtmlRenderer();
echo $renderer->render($form, '/submit', 'post');
```
## Next
Phase 3: More variable types (Phase 3)
Phase 4: Unit tests (comprehensive)

Add complete CRUD lifecycle integration test demonstrating V3 forms. ## Test Coverage **CrudFormTest** - 9 tests, 69 assertions, all passing ✓ Tests complete form lifecycle: 1. Create phase - blank form rendering 2. Validation with errors - error display 3. Validation with valid data - success path 4. Edit phase - form with existing data 5. Update phase - editing existing data 6. Display phase - read-only view 7. Complete lifecycle - create → validate → save → edit → update 8. Multiple data types - validation of all types 9. Section organization - grouped fields ## Data Types Demonstrated - **Text** (name) - basic text input - **Email** (email) - HTML5 email validation - **Enum** (status dropdown) - select with options - **Boolean** (notifications) - checkbox - **Date** (registration date) - HTML5 date picker - **Longtext** (notes) - textarea ## Lifecycle Phases **Create:** - Blank form - Field rendering - Required markers - Help text **Validate:** - Error detection - Error display - Value preservation - Success case **Edit:** - Pre-filled values - Hidden ID field - Existing data loading **Update:** - Change detection - Data extraction - ID preservation **Display:** - Read-only rendering - All fields disabled ## Features Tested - Form creation with multiple types - Validation (required fields, email format) - Error handling and display - Data extraction (getInfo) - Hidden fields - Section organization - Read-only mode - HTML rendering ## Fixes Fixed BaseRenderer hidden field rendering: - Wrap array in Horde_Variables before getValue() - Fixes "Call to member function get() on array" error Related: #19
Add controlMode support to HtmlControlRenderer and HtmlRenderer: - modern: HTML5 native controls (date, time, datetime-local) - default - legacy: JavaScript-based pickers (for older browsers) - fallback: Plain text inputs with pattern validation Date/time/datetime fields now support all three rendering modes with appropriate value formatting and asset management hooks for legacy mode. Implement three remaining actions: - ConditionalsetvalueAction: Maps source values to target values - UpdatefieldAction: Concatenates fields using format string - SetcursorposAction: Sets cursor position in text fields All actions follow V3 patterns with strict typing, named parameters, and modern JavaScript generation. Add comprehensive ControlModeTest demonstrating: - Modern mode with HTML5 controls - Legacy mode with JS picker classes - Fallback mode with pattern validation - Dynamic mode switching - Value formatting for various date/time formats All 8 tests pass (48 assertions).
Fix validation and getInfo behavior: 1. Array validation: Check if array is empty when required - Empty arrays now fail validation when field is required - testValidateReturnsFalseForRequiredArrayEmpty now passes 2. getInfo() signature: Return value directly (V3 pattern) - V3 returns value (doesn't use reference parameter like lib/) - Updated tests to use return value instead of reference - testGetInfoReturnsValue now passes - testGetInfoWrapperForCompatibility now passes All 94 V3 tests now pass (24 skipped).
Implement renderers for commonly used variable types: Input types: - address: Textarea for address input with parsing support - phone/cellphone: HTML5 tel input with validation pattern - creditcard: Text input with credit card pattern and autocomplete - link: HTML5 URL input type - ipaddress: Text input with IPv4 pattern validation - octal: Text input for octal numbers (file permissions) Selection types: - country: Dropdown (extends enum, uses Horde_Nls) - set: Checkbox group for multiple selections Visual types: - colorpicker: HTML5 color input type - monthyear: HTML5 month input type - header: H3 heading for section headers - spacer: HR element for visual separation - html: Raw HTML content display - image: File input (accept="image/*") or img tag for display - invalid: Special field that always fails validation All renderers follow modern HTML5 patterns where applicable: - Semantic input types (tel, url, color, month) - Pattern validation - Autocomplete hints - Accessible markup Total renderers: 30 (15 existing + 15 new) Remaining types to implement: 28
Complete 100% renderer coverage - all 57 variable types now have renderers! Confirmation fields: - passwordconfirm: Two password fields with match validation - emailconfirm: Two email fields with match validation Lists and arrays: - stringlist: Text input for comma-separated strings - stringarray: Textarea for array of strings - intlist: Text input for comma-separated integers Time variations: - hourminutesecond: Time input with seconds (step=1) - monthdayyear: Date selector (uses HTML5 date input) Advanced inputs: - countedtext: Text input with character counter - ip6address: IPv6 address with pattern validation File inputs: - selectfiles: File input with multiple selection - sound: Audio file upload with player in readonly mode Dynamic/Complex: - sorter: Drag-drop list sorter (basic implementation) - assign: Assign items between lists (basic implementation) - matrix: Matrix/grid selection (placeholder) - tableset: Tabular data input (placeholder) - dblookup: Database lookup with autocomplete class - obrowser: Object browser with browse button - captcha: CAPTCHA field with placeholder Security: - pgp: PGP key textarea with appropriate placeholder - smime: S/MIME certificate textarea Display: - description: Display-only paragraph text - figlet: ASCII art preformatted text Variants: - addresslink: Address with link (uses address renderer) - mlenum: Multi-language enum (uses enum renderer) - category: Hierarchical category (uses enum renderer) - keyvalmultienum: Key-value multi-select (uses multienum renderer) Total renderers: 65 methods (57 types + 8 mode variants) Coverage: 100% (57/57 variable types) All renderers follow modern HTML5 patterns where applicable.
- Replace fully qualified \Horde\Form\Form with use statement - Replace [email protected] with [email protected] - Add use Horde\Form\Form; to Action, BaseAction, BaseRenderer, Renderer - Cleaner, more maintainable code style
Add comprehensive test coverage: - FormTest: Form lifecycle, validation, rendering - ActionTest: Form action handling - VariableTest: Form variable behavior - Type tests: Enum and Text field types - Integration test: Full form workflow Tests use PHPUnit 11+ attributes and modern assertions.
