Quick Start

Create a Form:

use Assegai\Forms\Form;
use Assegai\Forms\Enumerations\HttpMethod;

$form = new Form(
    method: HttpMethod::POST,
    selector: '#contact-form'
);

Add Form Fields:

$form->set('name', '');
$form->set('email', '');
$form->set('message', '');

Process Form Submission:

if ($form->isSubmitted()) {
    // Validate the form
    $form->validate();
    if ($form->isValid()) {
        // Process the form data
        $data = $form->getData();
        // ...
    } else {
        $errors = $form->getErrors();
        // Handle validation errors
    }
}

Render the Form:
```
echo $form->render();
```

Advanced Usage

Adding Validation Rules

use Assegai\Forms\Form;
use Assegai\Forms\Enumerations\HttpMethod;
use Assegai\Forms\FormControls\TextField;

$form = new Form(method: HttpMethod::POST, selector: '#user-form');

// Create a field with validation rules
$nameField = new TextField('name', '', ['required', 'min:3']);
$form->addField($nameField);

// Or add fields and set validation rules later
$form->set('email', '');
$emailField = $form->getField('email');
$emailField->addValidationRules('required', 'email');

Getting Form Data

// Get data as an associative array
$data = $form->getData();

// Get data as a stdClass object
$dataObject = $form->getData(asObject: true);

Working with Individual Fields

// Check if a field exists
if ($form->has('name')) {
    // Get a specific field value
    $name = $form->getFieldValue('name');

    // Get the field object
    $nameField = $form->getField('name');

    // Remove a field
    $form->removeField('name');
}

Form HTTP Methods

The form supports multiple HTTP methods:

use Assegai\Forms\Enumerations\HttpMethod;

// POST forms
$postForm = new Form(method: HttpMethod::POST, selector: '#form');

// GET forms
$getForm = new Form(method: HttpMethod::GET, selector: '#search');

// PUT/PATCH forms for updates
$updateForm = new Form(method: HttpMethod::PUT, selector: '#update-form');
$patchForm = new Form(method: HttpMethod::PATCH, selector: '#patch-form');

Form Selector

The selector parameter can be used to set the form's ID, CSS class, or action URL:

// Set the form ID
$form = new Form(selector: '#my-form');

// Set the form CSS classes
$form = new Form(selector: '.form-class1.form-class2');

// Set the form action URL
$form = new Form(selector: '/submit-form');
