FormNumber

The FormNumber view helper can be used to render a <input type="number"> HTML form input. It is meant to work with the Zend\Form\Element\Number element, which provides a default input specification for validating numerical values.

FormNumber extends from Zend\Form\View\Helper\FormInput.

Basic usage:

use Zend\Form\Element;

$element = new Element\Number('my-number');

// Within your view...
echo $this->formNumber($element);

Output:

<input type="number" name="my-number" value="">

Usage of min, max and step attributes:

use Zend\Form\Element;

$element = new Element\Number('my-number');
$element->setAttributes(
    array(
        'min'  => 5,
        'max'  => 20,
        'step' => 0.5,
    )
);
$element->setValue(12);

// Within your view...
echo $this->formNumber($element);

Output:

<input type="number" name="my-number" min="5" max="20" step="0.5" value="12">
