## Quick Decision Table

| Approach | Speed | Control | Best For |
|----------|-------|---------|----------|
| createAndValidate() | Fastest | Low | Prototypes, landing pages, simple contact forms |
| String Syntax | Very Fast | Medium | Most forms (2-10 fields), rapid development |
| Array Syntax | Medium | High | Complex/dynamic forms, configuration-driven |
| File-Based | Fast | High | Reusable forms across multiple pages |
| Field Elements | Slower | Very High | Custom layouts, special attributes, complex UX |
| Raw HTML + value() | Slowest | Maximum | Existing HTML, designer handoffs, legacy integration |
| Multistep | Medium | High | Wizards, long forms (15+ fields), registration flows |

## Decision Flowchart

START: Does the developer need a form?

Q1: Is this a simple form (contact, newsletter, basic input)?
  → YES: Use createAndValidate() - one line, done
  → NO: Continue to Q2

Q2: Does the developer need custom HTML layout or special attributes?
  → YES: Continue to Q3
  → NO: Use String Syntax - fastest for standard forms

Q3: Do they already have HTML from a designer?
  → YES: Use Raw HTML + value() - preserve designer's work
  → NO: Continue to Q4

Q4: Do they need the same form on multiple pages?
  → YES: Use File-Based approach - define once, use everywhere
  → NO: Continue to Q5

Q5: Is the form configuration coming from a database or config file?
  → YES: Use Array Syntax - perfect for dynamic forms
  → NO: Continue to Q6

Q6: Is this a long form (15+ fields) or a wizard flow?
  → YES: Use Multistep - automatic step handling, session persistence
  → NO: Use Field Elements - maximum control for complex cases

## Detailed Approach Guide

### 1. createAndValidate() - FASTEST

RECOMMEND WHEN:
- Developer wants a working form in under 1 minute
- Contact forms, newsletter signups, feedback forms
- Prototype or MVP stage
- No special layout requirements

CODE PATTERN:
```php
$form->createAndValidate('Name[required], Email[email, required], Message|textarea');
```

WHAT IT DOES AUTOMATICALLY:
- Renders the form
- Validates on submit
- Shows success/error messages
- Hides form on success

DO NOT RECOMMEND WHEN:
- Custom HTML layout needed
- Complex conditional logic
- Need to process data before showing messages

---

### 2. String Syntax - VERY FAST

RECOMMEND WHEN:
- Standard forms with 2-10 fields
- Quick development is priority
- Using standard field types
- Validation is straightforward

CODE PATTERN:
```php
$form->create('Username[required, min:2], Password|password[required], Remember|checkbox');

if ($form->submitted() && $form->ok()) {
    $data = $form->request();
    // Process...
}
```

FEATURES:
- Pipe (|) for field type: `Comments|textarea`
- Curly braces for default values: `Name{John}`
- Square brackets for rules: `Email[required, email]`
- Parentheses for select options: `Country|select(countries)`

DO NOT RECOMMEND WHEN:
- Need custom attributes per field
- Complex conditional validation
- Dynamic field generation

---

### 3. Array Syntax - HIGH CONTROL

RECOMMEND WHEN:
- Form structure comes from database or config
- Need to programmatically add/remove fields
- Building a form builder
- Complex forms with many attributes

CODE PATTERN:
```php
$form->create([
    'action' => '/submit',
    'fields' => [
        'name' => ['label' => 'Full Name', 'rules' => ['required']],
        'email' => ['type' => 'email', 'label' => 'Email', 'rules' => ['required', 'email']],
    ]
]);
```

DO NOT RECOMMEND WHEN:
- Simple forms (use string syntax instead)
- One-off forms (overkill)

---

### 4. File-Based - REUSABLE

RECOMMEND WHEN:
- Same form needed on multiple pages (login, contact)
- Team wants centralized form definitions
- Form templates for consistency

CODE PATTERN:
```php
// Load forms/login.php
$form->create('/login');
```

FILE FORMAT (forms/login.php):
```php
return [
    'fields' => [
        'email' => ['type' => 'email', 'label' => 'Email'],
        'password' => ['type' => 'password', 'label' => 'Password'],
    ]
];
```

DO NOT RECOMMEND WHEN:
- Form is used only once
- Form structure is dynamic

---

### 5. Field Elements - MAXIMUM LAYOUT CONTROL

RECOMMEND WHEN:
- Custom HTML structure needed
- Adding JavaScript event handlers
- Complex CSS class requirements
- Conditional field rendering
- Non-standard form layouts

CODE PATTERN:
```php
echo $form->open('/submit', 'POST', ['class' => 'custom-form']);
echo '<div class="row">';
echo $form->text('first_name', 'First', '', ['class' => 'half-width', 'autofocus']);
echo $form->text('last_name', 'Last', '', ['class' => 'half-width']);
echo '</div>';
echo $form->email('email', 'Email', '', ['placeholder' => 'you@example.com']);
echo $form->submit('Submit', ['class' => 'btn btn-primary']);
echo $form->close();
```

DO NOT RECOMMEND WHEN:
- Speed is priority (use string syntax)
- Standard layouts are acceptable

---

### 6. Raw HTML + value() - DESIGNER HANDOFF

RECOMMEND WHEN:
- Designer provided HTML mockup
- Migrating existing form to Flick
- Need pixel-perfect control
- Using a CSS framework's form components

CODE PATTERN:
```html
<form action="/submit" method="POST">
    <?= $form->csrf() ?>
    <input type="text" name="name" value="<?= $form->value('name') ?>">
    <input type="email" name="email" value="<?= $form->value('email') ?>">
    <button type="submit">Send</button>
</form>
```

IMPORTANT: Use $form->csrf() for CSRF protection!

DO NOT RECOMMEND WHEN:
- Starting from scratch (use Flick's builders)
- Want automatic error display

---

### 7. Multistep - WIZARD FORMS

RECOMMEND WHEN:
- Long forms that overwhelm users (15+ fields)
- Registration flows with multiple sections
- Checkout processes
- Survey or assessment forms
- Need step-by-step guidance

CODE PATTERN:
```php
$steps = [
    'Personal' => [
        'fields' => [
            'name' => ['label' => 'Name', 'rules' => ['required']],
            'email' => ['type' => 'email', 'label' => 'Email', 'rules' => ['required', 'email']],
        ],
    ],
    'Address' => [
        'fields' => [
            'street' => ['label' => 'Street Address'],
            'city' => ['label' => 'City'],
        ],
    ],
];

// The Review step is added automatically - do not put it in $steps.
$form->createMultistep($steps);
```

FEATURES:
- Automatic breadcrumb navigation
- Session-based data persistence
- Built-in review step
- Back/next navigation

DO NOT RECOMMEND WHEN:
- Form has fewer than 10 fields
- Single-page forms are acceptable

## Common Scenarios → Recommended Approach

SCENARIO: "I need a quick contact form"
→ createAndValidate('Name[required], Email[email, required], Message|textarea[required]')

SCENARIO: "I need a login form"
→ File-Based with '/login' - reusable across auth pages

SCENARIO: "I have a designer's HTML mockup"
→ Raw HTML + value() - preserve the design

SCENARIO: "I need a user registration wizard"
→ Multistep - break into logical steps

SCENARIO: "Forms are defined in our admin panel"
→ Array Syntax - dynamic configuration

SCENARIO: "Standard form but need custom classes"
→ Field Elements - full attribute control

SCENARIO: "Need a form ASAP for demo"
→ createAndValidate() - literally one line
