Standalone Form for PHP

The minimal stuff you need to create and validate your form. If you want to use a powerful validation and filtering use something like [Aura.Filter][] or your favourite component that does it. You can see how you can do it in the example in master branch.

The composer.json file

{
    "require": {
        "aura/input": ">=1.0.0, <=2.0.0",
        "aura/html": "2.0.*"
    }
}

The page which you need to bring the form.

use Aura\Input\Builder;
use Aura\Input\Filter;
use Aura\Input\Form;
use Aura\Html\HelperLocatorFactory;

$loader = require dirname(__DIR__) . '/vendor/autoload.php';

Creating your Form class

To create your form extend the class with Aura\Input\Form . Here is an example of contact form with fields name, email, url and message in it.

class ContactForm extends Form
{
    public function init()
    {
        $this->setField('name')
            ->setAttribs([
                'id' => 'contact[name]',
                'name' => 'contact[name]',
                'size' => 20,
                'maxlength' => 20,
            ]);
        $this->setField('email')
            ->setAttribs([
                'id' => 'contact[email]',
                'name' => 'contact[email]',
                'size' => 20,
                'maxlength' => 20,
            ]);
        $this->setField('url')
            ->setAttribs([
                'id' => 'contact[url]',
                'name' => 'contact[url]',
                'size' => 20,
                'maxlength' => 20,
            ]);
        $this->setField('message', 'textarea')
            ->setAttribs([
                'id' => 'contact[message]',
                'name' => 'contact[message]',
                'cols' => 40,
                'rows' => 5,
            ]);
        $this->setField('submit', 'submit')
            ->setAttribs(['value' => 'send']);

        $filter = $this->getFilter();

        $filter->setRule(
            'name',
            'Name must be alphabetic only.',
            function ($value) {
                return ctype_alpha($value);
            }
        );

        $filter->setRule(
            'email', 
            'Enter a valid email address', 
            function ($value) {
                return filter_var($value, FILTER_VALIDATE_EMAIL);
            }
        );

        $filter->setRule(
            'url', 
            'Enter a valid url', 
            function ($value) {
                return filter_var($value, FILTER_VALIDATE_URL);
            }
        );

        $filter->setRule(
            'message', 
            'Message should be more than 7 characters', 
            function ($value) {
                if (strlen($value) > 7) {
                    return true;
                }
                return false;
            }
        );
    }
}

Now create the object of Form passing the Aura\Input\Builder object and object of type Aura\Input\FilterInterface. As we are using the base filter of Aura.Input pass Aura\Input\Filter.

$form = new ContactForm(new Builder(), new Filter());

if (isset($_POST['submit']) && $_POST['submit'] == 'send') {    
    $data = $_POST['contact'];
    $form->fill($data);
    if ($form->filter()) {
        echo "Yes successfully validated and filtered";
        var_dump($data);
        exit;
    }
}

$factory = new HelperLocatorFactory();
$helper = $factory->newInstance();

function showFieldErrors($form, $name) {
    $errors = $form->getMessages($name);
    $str = '';
    if ($errors) {
        $str .= '<ul>';
        foreach ($errors as $error) {
            $str .= '<li>' . $error . '</li>';
        }
        $str .= '</ul>';
    }
    return $str;
}
